    (2021) SILVA, Michel V. Lemes da; NUNES FILHO, Antonio C. B.; ROSA, Vitor E. E.; CAIXETA, Adriano; LEMOS NETO, Pedro A.; RIBEIRO, Henrique B.; ALMEIDA, Breno O.; MARIANI JR., Jose; CAMPOS, Carlos M.; ABIZAID, Alexandre A.

    Background Chronic kidney disease is commonly found in patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) and has marked impact in their prognosis. It has been shown however that TAVR may improve renal function by alleviating the hemodynamic barrier imposed by AS. Nevertheless, the predictors of and clinical consequences of renal function improvement are not well established. Our aim was to assess the predictors of improvement of renal function after TAVR. Methods The present work is an analysis of the Brazilian Registry of TAVR, a national non-randomized prospective study with 22 Brazilian centers. Patients with baseline renal dysfunction (estimated glomerular filtration rate [eGFR] < 60mL/min/1.73m(2)) were stratified according to renal function after TAVR: increase >10% in eGFR were classified as TAVR induced renal function improvement (TIRFI); decrease > 10% in eGFR were classified as acute kidney injury (AKI) and stable renal function (neither criteria). Results A total of 819 consecutive patients with symptomatic severe AS were included. Of these, baseline renal dysfunction (estimated glomerular filtration rate [eGFR] < 60mL/min/1.73m(2)) was present in 577 (70%) patients. Considering variance in renal function between baseline and at discharge after TAVR procedure, TIRFI was seen in 197 (34.1%) patients, AKI in 203 (35.2%), and stable renal function in 177 (30.7%). The independent predictors of TIRFI were: absence of coronary artery disease (OR: 0.69; 95% CI 0.48-0.98; P = 0.039) and lower baseline eGFR (OR: 0.98; 95% CI 0.97-1.00; P = 0.039). There was no significant difference in 30-day and 1-year all-cause mortality between patients with stable renal function or TIRFI. Nonetheless, individuals that had AKI after TAVR presented higher mortality compared with TIRFI and stable renal function groups (29.3% vs. 15.4% vs. 9.5%, respectively; p < 0.001). Conclusions TIRFI was frequently found among baseline impaired renal function individuals but was not associated with improved 1-year outcomes.

    Longitudinal Shortening of the Left Ventricle by Cine-CMR for Assessment of Diastolic Function in Patients with Aortic Valve Disease
    (2020) RIBEIRO, Sergio Marrone; AZEVEDO FILHO, Clerio Francisco de; SAMPAIO, Roney; TARASOUTCHI, Flavio; GRINBERG, Max; KALIL-FILHO, Roberto; ROCHITTE, Carlos Eduardo
    Background: Diastolic dysfunction, commonly evaluated by echocardiography, is an important early finding in many cardiomyopathies. Cardiac magnetic resonance (CMR) often requires specialized sequences that extends the test time. Recently, feature-tracking imaging has been made available, but still requires expensive software and lacks clinical validation. Objective: To assess diastolic function in patients with aortic valve disease (AVD) and compare it with normal controls by evaluating left ventricular (LV) longitudinal displacement by CMR. Methods: We compared 26 AVD patients with 19 normal controls. Diastolic function was evaluated as LV longitudinal displacement in 4-chamber view cine-CMR images using steady state free precession (SSFP) sequence during the entire cardiac cycle with temporal resolution < 50 ms. The resulting plot of atrioventricular junction (AVJ) position versus time generated variables of AVJ motion. Significance level of p < 0.05 was used. Results: Maximum longitudinal displacement (0.12 vs. 0.17 cm), maximum velocity during early diastole (MVED, 0.6 vs. 1.4s(-1)), slope of the best-fit line of displacement in diastasis (VDS, 0.22 vs. 0.03s(-1)), and VDS/MVED ratio (0.35 vs. 0.02) were significantly reduced in AVD patients compared with controls, respectively. Aortic regurgitation showed significantly worse longitudinal LV shortening compared with aortic stenosis. Higher LV mass indicated worse diastolic dysfunction. Conclusions: A simple linear measurement detected significant differences on LV diastolic function between AVD patients and controls. LV mass was the only independent predictor of diastolic dysfunction in these patients. This method can help in the evaluation of diastolic dysfunction, improving cardiomyopathy detection by CMR, without prolonging exam time or depending on expensive software.

    Impact of Acute Kidney Injury on Short- and Long-term Outcomes After Transcatheter Aortic Valve Implantation
    (2019) NUNES FILHO, Antonio C. B.; KATZ, Marcelo; CAMPOS, Carlos M.; CARVALHO, Luiz A.; SIQUEIRA, Dimytri A.; TUMELERO, Rogerio T.; PORTELLA, Antenor L. F.; ESTEVES, Vinicius; PERIN, Marco A.; SARMENTO-LEITE, Rogerio; LEMOS NETO, Pedro A.; TARASOUTCHI, Flavio; BEZERRA, Hiram G.; BRITO JR., Fabio S. de
    Introduction and objectives: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI) and is associated with higher mortality. However, the impact of AKI on long-term outcomes remains controversial. Therefore, we sought to evaluate the impact of AKI on short- and long-term outcomes following TAVI using the Valve Academic Research Consortium 2 criteria. Methods: Consecutive patients (n = 794) with severe aortic stenosis who underwent TAVI were included in a multicenter Brazilian registry. Logistic regression analysis was used to identify predictors of AKI. Four-year outcomes were determined as Kaplan-Meier survival curves, and an adjusted landmark analysis was used to test the impact of AKI on mortality among survivors at 12 months. Results: The incidence of AKI after TAVI was 18%. Independent predictors of AKI were age, diabetes mellitus, major or life-threatening bleeding and valve malpositioning. Acute kidney injury was independently associated with higher risk of all-cause death (adjusted HR, 2.8; 95%CI, 2.0-3.9; P < .001) and cardiovascular mortality (adjusted HR, 2.9; 95%CI, 1.9-4.4; P < .001) over the entire follow-up period. However, when considering only survivors at 12 months, there was no difference in both clinical endpoints (adjusted HR, 1.2; 95%CI, 0.5-2.4; P = .71, and HR, 0.7; 95%CI, 0.2-2.1; P = .57, respectively). Conclusions: Acute kidney injury is a frequent complication after TAVI. Older age, diabetes, major or life-threatening bleeding, and valve malpositioning were independent predictors of AKI. Acute kidney injury is associated with worse short- and long-term outcomes. However, the major impact of AKI on mortality is limited to the first year after TAVI.

    Gender-Related Differences on Short- and Long-Term Outcomes of Patients Undergoing Transcatheter Aortic Valve Implantation
    (2017) KATZ, Marcelo; NUNES FILHO, Antonio Carlos Bacelar; CAIXETA, Adriano; CARVALHO, Luiz Antonio; SARMENTO-LEITE, Rogerio; LEMOS NETO, Pedro Alves; THIAGO, Luiz Eduardo Koenig Sao; OLIVEIRA, Adriano Dias Dourado; MARINO, Marcos Antonio; TUMELERO, Rogerio Tadeu; PERIN, Marco Antonio; ABIZAID, Alexandre; TARASOUTCHI, Flavio; BRITO JR., Fabio Sandoli de
    Objectives: This study aimed to compare gender-related differences in outcomes of patients undergoing TAVI over a long-term follow-up period. Background: Transcatheter aortic valve implantation (TAVI) has been considered the standard therapy for patients with inoperable or high-risk symptomatic aortic stenosis. The influence of gender-related differences in outcomes of patients undergoing TAVI is currently on debate. Methods: From January 2008 to January 2015, 819 patients (49% men) underwent TAVI and were included in a multicenter Brazilian registry. Patients were followed-up and clinical outcomes were evaluated according to the updated Valve Academic Research Consortium-2 criteria. Results: Mean follow-up was 4976478 days. Compared with women, men had a lower rate of major or life-threatening bleeding (12.0% vs. 20.6%; HR = 0.57 [95CI% 0.40-0.81]; P = 0.001), and major vascular complications (6% vs. 11.7%; HR = 0.50 [95CI% 0.31-0.82]; P = 0.004). At 30 days, all-cause mortality was lower in men than in women (6.5% vs. 11.5%; P = 0.013), however, cumulative all-cause mortality was similar between groups (25.9% vs. 29.7%, men and women, respectively, HR = 0.92 [95CI% 0.71-1.19]; P = 0.52) over the entire follow-up period. By adjusted Cox regression model, renal function, diabetes, peripheral artery disease, and chronic obstructive pulmonary disease (COPD) remained independently predictors of all-cause mortality. Conclusions: In this large-scale study evaluating patients undergoing TAVI, 30-day mortality was higher among women than men driven by significant higher rates of major or life-threatening bleeding and major vascular complications. However, all-cause mortality on long-term follow-up was similar between groups. (C) 2016 Wiley Periodicals, Inc.

    BACKGROUND Transfemoral aortic valve replacement (TAVR) is a guideline-recommended treatment option for patients with severe aortic valve stenosis. Women and men present with different baseline characteristics, which may influence procedural outcomes. OBJECTIVES This study sought to evaluate differences between women and men undergoing transfemoral TAVR across the globe during the last decade. METHODS The CENTER (Cerebrovascular EveNts in patients undergoing TranscathetER aortic valve implantation with balloon-expandable valves versus self-expandable valves)-collaboration was a global patient level dataset of patients undergoing transfemoral TAVR (N = 12,381) from 2007 to 2018. In this retrospective analysis, the study examined differences in baseline patient characteristics, 30-day stroke and mortality, and in-hospital outcomes between female and male patients. The study also assessed for temporal changes in outcomes and predictors for mortality per sex. RESULTS We included 58% (n = 7,120) female and 42% (n = 5,261) male patients. Women had higher prevalence of hypertension and glomerular filtration rate <30 ml/min/1.73 m(2) but lower prevalence of all other traditional cardiovascular comorbidities. Both sexes had similar rates of 30-day stroke (2.3% vs. 2.5%; p = 0.53) and mortality (5.9% vs. 5.5%; p = 0.17). In contrast, women had a 50% higher risk of life-threatening or major bleeding (6.7% vs. 4.4%; p < 0.01). Over the study period, mortality rates decreased to a greater extent in men than in women (60% vs. 50% reduction; both p < 0.001), with no reductions in stroke rates over time. CONCLUSIONS In this global collaboration, women and men had similar rates of 30-day mortality and stroke. However, women had higher rates of procedural life-threatening or major bleeding after TAVR. Between 2007 and 2018, mortality rates decreased to a greater extent in men than in women. (C) 2019 Published by Elsevier on behalf of the American College of Cardiology Foundation.

    Postoperative myocardial fibrosis assessment in aortic valvular heart diseases-a cardiovascular magnetic resonance study
    (2023) PIRES, Lucas T.; ROSA, Vitor E. E.; MORAIS, Thamara C.; BELLO, Juliana H. S. M.; FERNANDES, Joao R. C.; SANTIS, Antonio de; LOPES, Mariana P.; GUTIERREZ, Paulo S.; ROCHITTE, Carlos E.; NOMURA, Cesar H.; POMERANTZEFF, Pablo M. A.; SAMPAIO, Roney O.; TARASOUTCHI, Flavio
    Aims Left ventricular remodelling occurs during the chronic course of aortic regurgitation (AR) and aortic stenosis (AS), leading to myocardial hypertrophy and fibrosis. Several studies have shown that extracellular volume fraction (ECV) and indexed extracellular volume (iECV) are important surrogate markers of diffuse myocardial fibrosis (MF). Postoperative data on these cardiovascular magnetic resonance (CMR) extracellular expansion parameters for either AS or AR are scarce. This study aimed to demonstrate the postoperative changes that occur in diffuse MF, and the influence of preoperative MF on the reversal of LV remodelling, in patients with AR or AS. Methods and results Patients with severe AR or AS and indications for surgery were prospectively enrolled. Patients underwent pre- and postoperative CMR, and ECV and iECV were quantified. Data from 99 patients were analysed (32 with AR and 67 with AS). After surgery, the left ventricle mass index decreased in both groups (AR: 110 vs. 91 g/m(2); AS: 86 vs. 68 g/m(2), both P < 0.001). The late gadolinium enhancement fraction (AR: preoperative 1.9% vs. postoperative 1.7%, P = 0.575; AS: preoperative 2.4% vs. postoperative 2.4%, P = 0.615) and late gadolinium enhancement mass (AR: preoperative 3.8 g vs. postoperative 2.5 g, P = 0.635; AS: preoperative 3.4 g vs. postoperative 3.5 g, P = 0.575) remained stable in both groups. Preoperative iECV and ECV were greater in the AR group (iECV: 30 mL/m(2) vs. 22 mL/m(2), P = 0.001; ECV: 28.4% vs. 27.2%, P = 0.048). Indexed extracellular volume decreased after surgery in both groups (AR: 30-26.5 mL/m(2), AS: 22-18.2 mL/m(2), both P < 0.001); it was still greater in the AR group (AR: 26.5 mL/m(2) vs. AS: 18.2 mL/m(2), P < 0.001). Postoperative ECV remained stable in the AR group (preoperative 28.4% vs. postoperative 29.9%; P = 0.617) and increased in the AS group (preoperative 27.2% vs. postoperative 28.6%; P = 0.033). Conclusion Patients with both AR or AS presented reduction in iECV after surgery, unfolding the reversible nature of diffuse MF. In contrast to patients with AS, those with AR developed postoperative iECV regression with stable ECV, suggesting a balanced reduction in both intracellular and extracellular myocardial components.

    Heyde's Syndrome: Therapeutic Strategies and Long-Term Follow-Up
    (2021) ROSA, Vitor Emer Egypto; RIBEIRO, Henrique Barbosa; FERNANDES, Joao Ricardo Cordeiro; SANTIS, Antonio de; SPINA, Guilherme Sobreira; PAIXAO, Milena Ribeiro; PIRES, Lucas Jose Tachotti; BETTEGA, Marcelo; ACCORSI, Tarso Augusto Duenhas; SAMPAIO, Roney Orismar; TARASOUTCHI, Flavio
    Background: Heyde's syndrome is the association of severe aortic stenosis with episodes of gastrointestinal due to angiodysplastic lesion. Little is known about the factors associated with new episodes of bleeding and long-term outcomes. Furthermore, most data are restricted to case reports and small case series. Objective: To assess the clinical, laboratory and echocardiography profile of patients with Heyde's syndrome who underwent valve intervention or drug therapy. Methods: Prospective cohort of 24 consecutive patients from 2005 to 2018. Clinical, laboratory and echocardiography data were assessed, as well as those related to valve intervention and to outcomes after diagnosis. Statistical significance was set p < 0.05. Results: Half of the 24 patients (50%) presented with bleeding requiring blood transfusion on admission. Angiodysplasias were more frequently found in the ascending colon (62%). Valve intervention (surgical or transcatheter) was performed in 70.8% of the patients, and 29.2% remained on drug therapy. News episodes of bleeding occurred in 25% of the cases, and there was no difference between clinical and intervention groups (28.6 vs 23.5%, p = 1.00; respectively). Mortality at 2-year and 5-year follow-up was 16% and 25%, with no difference between the groups (log-rank p = 0.185 and 0.737, respectively). Conclusions: Patients with Heyde's syndrome had a high rate of bleeding requiring blood transfusion on admission, suggesting that is a severe disease with high mortality risk. No difference was found between the groups subjected to clinical treatment and to valve intervention with regard to rates of rebleeding and late mortality.

    Desempenho de Escores de Risco Cirúrgico para Prever Mortalidade após Implante Transcateter de Valva Aórtica
    (2015) SILVA, Leonardo Sinnott; CARAMORI, Paulo Ricardo Avancini; NUNES FILHO, Antonio Carlos Bacelar; KATZ, Marcelo; GUARAGNA, Joao Carlos Vieira da Costa; LEMOS, Pedro; LIMA, Valter; ABIZAID, Alexandre; TARASOUTCHI, Flavio; BRITO JR., Fabio S. de
    Background: Predicting mortality in patients undergoing transcatheter aortic valve implantation (TAVI) remains a challenge. Objectives: To evaluate the performance of 5 risk scores for cardiac surgery in predicting the 30-day mortality among patients of the Brazilian Registry of TAVI. Methods: The Brazilian Multicenter Registry prospectively enrolled 418 patients undergoing TAVI in 18 centers between 2008 and 2013. The 30-day mortality risk was calculated using the following surgical scores: the logistic EuroSCORE I (ESI), EuroSCORE II (ESII), Society of Thoracic Surgeons (STS) score, Ambler score (AS) and Guaragna score (GS). The performance of the risk scores was evaluated in terms of their calibration (Hosmer-Lemeshow test) and discrimination [area under the receiver-operating characteristic curve (AUC)]. Results: The mean age was 81.5 +/- 7.7 years. The CoreValve (Medtronic) was used in 86.1% of the cohort, and the transfemoral approach was used in 96.2%. The observed 30-day mortality was 9.1%. The 30-day mortality predicted by the scores was as follows: ESI, 20.2 +/- 13.8%; ESII, 6.5 +/- 13.8%; STS score, 14.7 +/- 4.4%; AS, 7.0 +/- 3.8%; GS, 17.3 +/- 10.8%. Using AUC, none of the tested scores could accurately predict the 30-day mortality. AUC for the scores was as follows: 0.58 [95% confidence interval (CI): 0.49 to 0.68, p = 0.09] for ESI; 0.54 (95% CI: 0.44 to 0.64, p = 0.42) for ESII; 0.57 (95% CI: 0.47 to 0.67, p = 0.16) for AS; 0.48 (95% IC: 0.38 to 0.57, p = 0.68) for STS score; and 0.52 (95% CI: 0.42 to 0.62, p = 0.64) for GS. The Hosmer-Lemeshow test indicated acceptable calibration for all scores (p > 0.05). Conclusions: In this real world Brazilian registry, the surgical risk scores were inaccurate in predicting mortality after TAVI. Risk models specifically developed for TAVI are required.
