    Comparison of Inhaled Nitric Oxide Versus Oxygen on Hemodynamics in Patients With Mitral Stenosis and Severe Pulmonary Hypertension After Mitral Valve Surgery
    (2011) FERNANDES, Juliano L.; SAMPAIO, Roney O.; BRANDAO, Carlos M.; ACCORSI, Tarso Augusto D.; CARDOSO, Luiz F.; SPINA, Guilherme S.; TARASOUTCHI, Flavio; POMERANTZEFF, Pablo; AULER JR., Jose O.; GRINBERG, Max
    Pulmonary hypertension represents an important cause of morbidity and mortality in patients with mitral stenosis who undergo cardiac surgery, especially in the postoperative period. The aim of this study was to test the hypothesis that inhaled nitric oxide (iNO) would improve the hemodynamic effects and short-term clinical outcomes of patients with mitral stenosis and severe pulmonary hypertension who undergo cardiac surgery in a randomized, controlled study. Twenty-nine patients (4 men, 25 women; mean age 46 2 years) were randomly allocated to receive iNO (n = 14) or oxygen (n = 15) for 48 hours immediately after surgery. Hemodynamic data, the use of vasoactive drugs, duration of stay, and short-term complications were assessed. No differences in baseline characteristics were observed between the groups. After 24 and 48 hours, patients receiving iNO had a significantly greater increase in cardiac index compared to patients receiving oxygen (p < 0.0001). Pulmonary vascular resistance was also more significantly reduced in patients receiving iNO versus oxygen (-117 dyne/s/cm(5), 95% confidence interval 34 to 200, vs 40 dyne/s/cm5, 95% confidence interval 34 to 100, p = 0.005) at 48 hours. Patients in the iNO group used fewer systemic vasoactive drugs.(mean 2.1 +/- 0.14 vs 2.6 +/- 0.16, p = 0.046) and had a shorter intensive care unit stay (median 2 days, interquartile range 0.25, vs median 3 days, interquartile range 7, p = 0.02). In conclusion, iNO immediately after surgery in patients with mitral stenosis and severe pulmonary hypertension improves hemodynamics and may have short-term clinical benefits.

    Myocardial Fibrosis in Classical Low-Flow, Low-Gradient Aortic Stenosis Insights From a Cardiovascular Magnetic Resonance Study
    (2019) ROSA, Vitor E. E.; RIBEIRO, Henrique B.; SAMPAIO, Roney O.; MORAIS, Thamara C.; ROSA, Marcela E. E.; PIRES, Lucas J. T.; VIEIRA, Marcelo L. C.; MATHIAS JR., Wilson; ROCHITTE, Carlos E.; SANTIS, Antonio S. A. L. de; FERNANDES, Joao Ricardo C.; ACCORSI, Tarso A. D.; POMERANTZEFF, Pablo M. A.; RODES-CABAU, Josep; PIBAROT, Philippe; TARASOUTCHI, Flavio
    Background: Few data exist on the degree of interstitial myocardial fibrosis in patients with classical low-flow, low-gradient aortic stenosis (LFLG-AS) and its association with left ventricular flow reserve (FR) on dobutamine stress echocardiography. This study sought to evaluate the diffuse interstitial fibrosis measured by T1 mapping cardiac magnetic resonance technique in LFLG-AS patients with and without FR. Methods: Prospective study including 65 consecutive patients (41 LFLG-AS [mean age, 67.1 +/- 8.4 years; 83% men] and 24 high-gradient aortic stenosis used as controls) undergoing dobutamine stress echocardiography to assess FR and cardiac magnetic resonance to determine the extracellular volume (ECV) fraction of the myocardium, indexed ECV (iECV) to body surface area and late gadolinium enhancement. Results: Interstitial myocardial fibrosis measured by iECV was higher in patients with LFLG-AS with and without FR as compared with high-gradient aortic stenosis (35.25 +/- 9.75 versus 32.93 +/- 11.00 versus 21.19 +/- 6.47 mL/m(2), respectively; P<0.001). However, both ECV and iECV levels were similar between LFLG-AS patients with and without FR (P=0.950 and P=0.701, respectively). Also, FR did not correlate significantly with ECV (r=-0.16, P=0.31) or iECV (r=0.11, P=0.51). Late gadolinium enhancement mass was also similar in patients with versus without FR but lower in high-gradient aortic stenosis (13.3 +/- 10.2 versus 10.5 +/- 7.5 versus 4.8 +/- 5.9 g, respectively; P=0.018). Conclusions: Patients with LFLG-AS have higher ECV, iECV, and late gadolinium enhancement mass compared with high-gradient aortic stenosis. Moreover, among patients with LFLG-AS, the degree of myocardial fibrosis was similar in patients with versus those without FR. These findings suggest that diffuse myocardial fibrosis may not be the main factor responsible for the absence of FR in LFLG-AS patients.

    Quality improvement program in Latin America decreases mortality after cardiac surgery: a before-after intervention study
    (2022) MEJIA, Omar Asdrubal Vilca; BORGOMONI, Gabrielle Barbosa; DALLAN, Luis Roberto Palma; MIOTO, Bruno Mahler; ACCORSI, Tarso Augusto Duenhas; LIMA, Eduardo Gomes; SOEIRO, Alexandre de Matos; LIMA, Felipe Gallego; BRANDAO, Carlos Manuel de Almeida; POMERANTZEFF, Pablo Maria Alberto; DALLAN, Luis Alberto Oliveira; LISBOA, Luiz Augusto Ferreira
    Background: The current challenge of cardiac surgery (CS) is to improve outcomes in adverse scenarios. The aim of this study was to assess the impact of a quality improvement program (QIP) on hospital mortality in the largest CS center in Latin America.Methods: Patients were divided into two groups: before (Jan 2013-Dec 2015, n = 3534) and after establishment of the QIP (Jan 2017-Dec 2019, n = 3544). The QIP consisted of the implementation of 10 central initiatives during 2016. The procedures evaluated were isolated coronary artery bypass grafting surgery (CABG), mitral valve surgery, aortic valve surgery, combined mitral and aortic valve surgery, and CABG associated with heart valve surgery. Propensity Score Matching (PSM) was used to adjust for inequality in patients' preoperative characteristics before and after the implementation of QIP. A multivariate logistic regression model was built to predict hospital mortality and validated using discrimination and calibration metrics.Results: The PMS paired two groups using 5 variables, obtaining 858 patients operated before (non-QIP) and 858 patients operated after the implementation of the QIP. When comparing the QIP versus Non-QIP group, there was a shorter length of stay in all phases of hospitalization. In addition, the patients evolved with less anemia (P = 0.001), use of intra-aortic balloon pump (P = 0.003), atrial fibrillation (P = 0.001), acute kidney injury (P < 0.001), cardiogenic shock (P = 0.011), sepsis (P = 0.046), and hospital mortality (P = 0.001). In the multiple model, among the predictors of hospital mortality, the lack of QIP increased the chances of mortality by 2.09 times.Conclusion: The implementation of a first CS QIP in Latin America was associated with a reduction in length of hospital stay, complications and mortality after the cardiac surgeries analyzed.
