(2024) CARVALHO, Carlos Roberto Ribeiro; LAMAS, Celina de Almeida; LUNA, Luis Augusto Visani de; CHATE, Rodrigo Caruso; SALGE, Joao Marcos; SAWAMURA, Marcio Valente Yamada; TOUFEN, Carlos; GARCIA, Michelle Louvaes; SCUDELLER, Paula Gobi; NOMURA, Cesar Higa; GUTIERREZ, Marco Antonio; BALDI, Bruno Guedes
Background COVID-19 lung sequelae can impact the course of patient lives. We investigated the evolution of pulmonary abnormalities in post-COVID-19 patients 18-24 months after hospital discharge. Methods A cohort of COVID-19 patients admitted to the Hospital das Cl & iacute;nicas da Faculdade de Medicina da USP in S & atilde;o Paulo, Brazil, between March and August of 2020, were followed-up 6-12 months after hospital discharge. A subset of patients with pulmonary involvement and chest computed tomography (CT) scans were eligible to participate in this second follow-up (18-24 months). Data was analyzed in an ambidirectional manner, including retrospective data from the hospitalization, and from the first follow-up (6-12 months after discharge), and compared with the prospective data collected in this new follow-up. Findings From 348 patients eligible, 237 (68%) participated in this follow-up. Among participants, 139 (58%) patients presented ground-glass opacities and reticulations, and 80 (33%) presented fibrotic-like lesions (traction bronchiectasis and architectural distortion). Five (2%) patients improved compared to the 6-12-month assessment, but 20 (25%) of 80 presented worsening of lung abnormalities. For those with relevant assessments on both occasions, comparing the CT findings between this follow-up with the previous assessment, there was an increase in patients with architectural distortion (43 [21%] of 204 vs 57 [28%] of 204, p = 0.0093), as well as in traction bronchiectasis (55 [27%] of 204 vs 69 [34%] of 204, p = 0.0043). Patients presented a persistent functional impairment with demonstrated restrictive pattern in both follow-ups (87 [42%] of 207 vs 91 [44%] of 207, p = 0.76), as well as for the reduced diffusion capacity (88 [42%] of 208 vs 87 [42%] of 208, p = 1.0). Length of hospitalization (OR 1.04 [1.01-1.07], p = 0.0040), invasive mechanical ventilation (OR 3.11 [1.3-7.5] p = 0.011), patient's age (OR 1.03 [1.01-1.06] p = 0.0074 were consistent predictors for development of fibrotic-like lung lesions in post-COVID-19 patients. Interpretation Post-COVID-19 lung sequelae can persist and progress after hospital discharge, suggesting airways involvement and formation of new fibrotic-like lesions, mainly in patients who were in intensive care unit (ICU).

Sternal cleft: new options for reconstruction
(2024) MACEDO, Joao Paulo Cassiano de; ARAUJO, Pedro Henrique Xavier Nabuco de; CAMPOS, Jose Ribas Milanez de; PEGO-FERNANDES, Paulo Manuel
Sternal cleft (SC) is a rare congenital affection caused by the absence of sternal bar union. Diagnosis is generally made after birth due to paradoxical midline movement, although it can be made prenatally by ultrasonography. A computerized tomography scan (CT scan) after birth is generally used to confirm the diagnosis, assess other intrathoracic conditions, classify the SC, and plan for surgery. SC can be classified as complete or incomplete. A complete SC has a full gap between sternal bars. An incomplete SC is subdivided into superior or inferior, related to the point of bone fusion between the sternal bars. The goal of surgical treatment is to protect mediastinal structures. Many authors advocate the repair in newborn patients, although it can be performed in older patients. The main argument in its favor is the chest's flexibility, with a reduced risk of compression of the mediastinal structures. There are several cases of series and distinct surgical techniques in the literature. Some authors have suggested the use of autologous tissue, prosthetic material such as mesh, or titanium plates and screws. Although difficulties are often encountered in surgical access, they have not been discussed. Therefore, we are promoting modifications to the technique in response to this. The purpose is to show innovations, and how to deal with adversity during the procedure.

Changing trends in clinical characteristics and in-hospital mortality of patients with infective endocarditis over four decades
(2024) SANTOS, Diego Augusto Medeiros; SICILIANO, Rinaldo Focaccia; BESEN, Bruno Adler Maccagnan Pinheiro; STRABELLI, Tania Mara Varejao; SAMBO, Caio Trevelin; MILCZWSKI, Vitor de Medeiros; GOLDEMBERG, Flora; TARASOUTCHI, Flavio; VIEIRA, Marcelo Luiz Campos; PAIXAO, Milena Ribeiro; GUALANDRO, Danielle Menosi; ACCORSI, Tarso Augusto Duenhas; POMERANTZEFF, Pablo Maria Alberto; MANSUR, Alfredo Jose
Background: Infective endocarditis continues to be a significant concern and may be undergoing an epidemiological transition. Methods: Were studied 1804 consecutive episodes of infective endocarditis between 1978 and 2022. The mean age was 48 ( +/- 19), and 1162 (64%) patients were male. Temporal trends in demographic data, comorbidities, predisposing conditions, microorganisms, complications and in-hospital death have been studied over the decades (1978-1988, 1989-1999, 2000-2010 and 2011-2022). The outcomes and clinical characteristics were modeled using nonlinear cubic spline functions. Findings: Valve surgery was performed in 50% of the patients and overall in-hospital mortality was 30%. From the first to the fourth decade studied, the average age of patients increased from 29 to 57 years (p < 0.001), with significant declines in the occurrence of rheumatic valvular heart disease (15% to 6%; p < 0.001) and streptococcal infections (46% to 33%; p < 0.001). Healthcare-associated infections have increased (9% to 21%; p < 0.001), as have prosthetic valve endocarditis (26% to 53%; p < 0.001), coagulasenegative staphylococcal infections (4% to 11%; p < 0.001), and related-complications (heart failure, embolic events, and perivalvular abscess; p < 0.001). These changes were associated with a decline in adjusted inhospital mortality from 34% to 25% (p = 0.019). Interpretation: In the 44 years studied, there was an increase in the mean age of patients, healthcarerelated, prosthetic valve, coagulase-negative staphylococci/MRSA infections, and related complications. Notably, these epidemiological changes were associated with a decline in the adjusted in-hospital mortality.

(2023) MANSUR, Antonio de Padua; PEREIRA-BARRETTO, Antonio Carlos; CARLO, Carlos Henrique del; AVAKIAN, Solange Desiree; NAKAGAWA, Naomi Kondo; CESAR, Luiz Antonio Machado; BOCCHI, Edimar Alcides
Background: Limited research has explored sex-specific differences in death predictors of HF patients with ischemic (iCMP) and nonischemic (niCMP) cardiomyopathy. This study assessed sex differences in niCMP and iCMP prognosis. Methods: We studied 7487 patients with HF between February 2017 and September 2020. Clinical features and echocardiographic findings were collected. We used Kaplan-Meier, Cox proportional hazard models, and chi-square scores of Cox regression to determine death predictors in women and men. Results: The mean age was 64.3 +/- 14.2 years, with 4417 (59%) males. Women with iCMP and niCMP exhibited a significantly higher mean age, higher mean left ventricular ejection fraction, and smaller left ventricular diastolic diameter than men. Over 2.26 years of follow-up, 325 (14.7%) women and 420 (15.7%) men, and 211 women (24.5%) and 519 men (29.8%) with niCMP (p = NS) and iCMP (p = 0.004), respectively, died. The cumulative incidence of death was higher in men with iCMP (log-rank p < 0.0001) but similar with niCMP. Cox regression showed chronic kidney disease, diabetes, stroke, atrial fibrillation, age, and myocardial infarction as the main predictors of death for iCMP in women and men. Conclusions: Women exhibited a better prognosis than men with iCMP, but similar for niCMP. Nevertheless, sex was not an independent predictor of death for both CMP.

17β-estradiol and methylprednisolone association as a therapeutic option to modulate lung inflammation in brain-dead female rats
(2024) VIDAL-DOS-SANTOS, Marina; ANUNCIACAO, Lucas F.; ARMSTRONG-JR, Roberto; RICARDO-DA-SILVA, Fernanda Y.; RAMOS, Isabella Yumi Taira; CORREIA, Cristiano J.; MOREIRA, Luiz F. P.; LEUVENINK, Henri G. D.; BREITHAUPT-FALOPPA, Ana C.
Introduction: Brain death (BD) is known to compromise graft quality by causing hemodynamic, metabolic, and hormonal changes. The abrupt reduction of female sex hormones after BD was associated with increased lung inflammation. The use of both corticoids and estradiol independently has presented positive results in modulating BD-induced inflammatory response. However, studies have shown that for females the presence of both estrogen and corticoids is necessary to ensure adequate immune response. In that sense, this study aims to investigate how the association of methylprednisolone (MP) and estradiol (E2) could modulate the lung inflammation triggered by BD in female rats. Methods: Female Wistar rats (8 weeks) were divided into four groups: sham (animals submitted to the surgical process, without induction of BD), BD (animals submitted to BD), MP/E2 (animals submitted to BD that received MP and E2 treatment 3h after BD induction) and MP (animals submitted to BD that received MP treatment 3h after BD induction). Results: Hemodynamics, systemic and local quantification of IL-6, IL-1 beta, VEGF, and TNF-alpha, leukocyte infiltration to the lung parenchyma and airways, and adhesion molecule expression were analyzed. After treatment, MP/E2 association was able to reinstate mean arterial pressure to levels close to Sham animals (p<0.05). BD increased leukocyte infiltration to the airways and MP/E2 was able to reduce the number of cells (p=0.0139). Also, the associated treatment modulated the vasculature by reducing the expression of VEGF (p=0.0616) and maintaining eNOS levels (p=0.004) in lung tissue. Discussion: Data presented in this study show that the association between corticoids and estradiol could represent a better treatment strategy for lung inflammation in the female BD donor by presenting a positive effect in the hemodynamic management of the donor, as well as by reducing infiltrated leukocyte to the airways and release of inflammatory markers in the short and long term.

Electrical Impedance Tomography Identifies Evolution of Regional Perfusion in a Porcine Model of Acute Respiratory Distress Syndrome
(2023) MARTIN, Kevin T.; XIN, Yi; GAULTON, Timothy G.; VICTOR, Marcus; SANTIAGO, Roberta R.; KIM, Taehwan; MORAIS, Caio C. A.; KAZIMI, Aubrey A.; CONNELL, Marc; GERARD, Sarah E.; HERRMANN, Jacob; MUELLER, Ariel L.; LENART, Austin; SHEN, Jiacheng; KHAN, Sherbano S.; PETROV, Mihail; REUTLINGER, Kristan; ROZENBERG, Karina; AMATO, Marcelo; BERRA, Lorenzo; CEREDA, Maurizio
Background: Bedside electrical impedance tomography could be useful to visualize evolving pulmonary perfusion distributions when acute respiratory distress syndrome worsens or in response to ventilatory and positional therapies. In experimental acute respiratory distress syndrome, this study evaluated the agreement of electrical impedance tomography and dynamic contrast-enhanced computed tomography perfusion distributions at two injury time points and in response to increased positive end-expiratory pressure (PEEP) and prone position.Methods: Eleven mechanically ventilated (VT 8 ml kg(-1)) Yorkshire pigs (five male, six female) received bronchial hydrochloric acid (3.5 ml kg(-1)) to invoke lung injury. Electrical impedance tomography and computed tomography perfusion images were obtained at 2 h (early injury) and 24 h (late injury) after injury in supine position with PEEP 5 and 10 cm H2O. In eight animals, electrical impedance tomography and computed tomography perfusion imaging were also conducted in the prone position. Electrical impedance tomography perfusion (Q(EIT)) and computed tomography perfusion (Q(CT)) values (as percentages of image total) were compared in eight vertical regions across injury stages, levels of PEEP, and body positions using mixed-effects linear regression. The primary outcome was agreement between Q(EIT) and Q(CT,) defined using limits of agreement and Pearson correlation coefficient.Results: Pao(2)/Fio(2 )decreased over the course of the experiment (healthy to early injury, -253 [95% CI, -317 to -189]; early to late injury, -88 [95% CI, -151 to -24]). The limits of agreement between Q(EIT) and Q(CT) were -4.66% and 4.73% for the middle 50% quantile of average regional perfusion, and the correlation coefficient was 0.88 (95% CI, 0.86 to 0.90]; P < 0.001). Electrical impedance tomography and computed tomography showed similar perfusion redistributions over injury stages and in response to increased PEEP. Q(EIT) redistributions after positional therapy underestimated Q(CT) in ventral regions and overestimated Q(CT) in dorsal regions.Conclusions: Electrical impedance tomography closely approximated computed tomography perfusion measures in experimental acute respiratory distress syndrome, in the supine position, over injury progression and with increased PEEP. Further validation is needed to determine the accuracy of electrical impedance tomography in measuring perfusion redistributions after positional changes.

Electrical Impedance Tomography to Monitor Hypoxemic Respiratory Failure
(2024) FRANCHINEAU, Guillaume; JONKMAN, Annemijn H.; PIQUILLOUD, Lise; YOSHIDA, Takeshi; COSTA, Eduardo; ROZE, Hadrien; CAMPOROTA, Luigi; PIRAINO, Thomas; SPINELLI, Elena; COMBES, Alain; ALCALA, Glasiele C.; AMATO, Marcelo; MAURI, Tommaso; FRERICHS, Inez; BROCHARD, Laurent J.; SCHMIDT, Matthieu
Hypoxemic respiratory failure is one of the leading causes of mortality in intensive care. Frequent assessment of individual physiological characteristics and delivery of personalized mechanical ventilation (MV) settings is a constant challenge for clinicians caring for these patients. Electrical impedance tomography (EIT) is a radiation-free bedside monitoring device that is able to assess regional lung ventilation and changes in aeration. With real-time tomographic functional images of the lungs obtained through a thoracic belt, clinicians can visualize and estimate the distribution of ventilation at different ventilation settings or following procedures such as prone positioning. Several studies have evaluated the performance of EIT to monitor the effects of different MV settings in patients with acute respiratory distress syndrome, allowing more personalized MV. For instance, EIT could help clinicians find the positive end-expiratory pressure that represents a compromise between recruitment and overdistension and assess the effect of prone positioning on ventilation distribution. The clinical impact of the personalization of MV remains to be explored. Despite inherent limitations such as limited spatial resolution, EIT also offers a unique noninvasive bedside assessment of regional ventilation changes in the ICU. This technology offers the possibility of a continuous, operator-free diagnosis and real-time detection of common problems during MV. This review provides an overview of the functioning of EIT, its main indices, and its performance in monitoring patients with acute respiratory failure. Future perspectives for use in intensive care are also addressed.

Coronary Artery Disease Assessment and Cardiovascular Events in Middle-Aged Patients on Hemodialysis
(2024) GOWDAK, Luis Henrique Wolff; LIMA, Jose Jayme Galvao De; ADAM, Eduardo Leal; MANTA, Isabela Cristina Kirnew Abud; REUSING, Jose Otto; DAVID-NETO, Elias; CESAR, Luiz Antonio Machado; BORTOLOTTO, Luiz Aparecido
Objective: To explore whether, in younger patients on dialysis with longer life expectancy, assessment of coronary artery disease (CAD) could identify individuals at higher risk of events and revascularization might improve outcomes in selected patients contrary to what had been observed in elderly patients. Methods: From August 1997 to January 2019, 2265 patients with stage 5 chronic kidney disease were prospectively referred for cardiovascular assessment. For this study, we selected 1374 asymptomatic patients aged between 18 and 64 years. After clinical risk stratification and cardiac scintigraphy by single -photon emission computed tomography, 866 patients underwent coronary angiography. The primary end point was the composite incidence of nonfatal/fatal major adverse cardiovascular events during a follow-up period of 0.1 to 189.7 months (median, 26 months). The secondary end point was all -cause mortality. Results: The primary end point occurred in 327 (23.8%) patients. Clinically stratified high -risk patients had a 3 -fold increased risk of the primary end point. The prevalence of abnormal findings on perfusion scans was 29.2% (n=375), and significant CAD was found in 449 (51.8%) of 866 patients who underwent coronary angiography. An abnormal finding on myocardial perfusion scan and the presence of CAD were significantly associated with a 74% and 22% increased risk of cardiovascular events, respectively. In patients undergoing percutaneous coronary intervention or coronary artery bypass grafting (n=99), there was an 18% reduction in the risk of all -cause death relative to patients receiving medical treatment (P=.03). Conclusion: In this cohort of middle-aged, asymptomatic patients on dialysis, assessment of CAD identified individuals at higher risk of events, and coronary intervention was associated with reducing the risk of death in selected patients.

Challenges of Congenital Heart Surgery in Brazil: It is Time to Designate Pediatric Congenital Heart Surgery Subspecialty
(2024) PINTO JUNIOR, Valdester Cavalcante Pinto; MIANA, Leonardo Augusto; NAVARRO, Fabio Binhara; ROCHA, Bruno da Costa; ASSAD, Renato Samy; OLIVEIRA, Marcos Aurelio Barboza de; CROTI, Ulisses Alexandre; SALUM, Fabio Said; FURLANETTO, Beatriz Helena Sanches; JATENE, Marcelo Biscegli; CANEO, Luiz Fernando; MONTEIRO, Andrey Jose de Oliveira; NETO, Fernando Ribeiro de Moraes; ANTONIALI, Fernando; SALERNO, Pedro Rafael; NINA, Vinicius Jose da Silva
Congenital heart disease (CHD) affects eight to ten out of every 1,000 births, resulting in approximately 23,057 new cases in Brazil in 2022. About one in four children with CHD requires surgery or other procedures in the first year of life, and it is expected that approximately 81% of these children with CHD will survive until at least 35 years of age. Professionals choosing to specialize in CHD surgery face numerous challenges, not only related to mastering surgical techniques and the complexity of the diseases but also to the lack of recognition by medical societies as a separate subspecialty. Furthermore, families face difficulties when access to services capable of providing treatment for these children. To address these challenges, it is essential to have specialized hospitals, qualified professionals, updated technologies, sustainable industry, appropriate financing, quality assessment systems, and knowledge generation. The path to excellence involves specialization across all involved parties. As we reflect on the importance of Pediatric Cardiovascular Surgery and Congenital Heart Diseases establishing themselves as a subspecialty of Cardiovascular Surgery, it is essential to look beyond our borders to countries like the United States of America and United Kingdom, where this evolution is already a reality. This autonomy has led to significant advancements in research, education, and patient care outcomes, establishing a care model. By following this path in Brazil, we not only align our practice with the highest international standards but also demonstrate our maturity and the ability to meet the specific needs of patients with CHD and those with acquired childhood heart disease.
