RESUMO
OBJECTIVE: Owing to a lack of supportive data, tricuspid regurgitation (TR) is usually not addressed in patients undergoing coronary artery bypass grafting (CABG). Here we evaluated changes in TR degrees over time and its impact on survival in patients undergoing CABG. METHODS: We reviewed the data of 9726 patients who underwent isolated CABG between January 2000 and January 2021. According to preoperative TR severity, patients were stratified into nonsignificant (none to trivial, mild) and significant (moderate to severe) TR groups. We excluded patients who had undergone previous tricuspid valve surgery, pacemaker placement, and concomitant valve or ablative surgery. Propensity score matching and Cox proportional hazards models were used to identify associations between TR grade and the primary outcome of all-cause mortality. The secondary outcome was change in TR severity on the last echocardiogram. RESULTS: After propensity score matching, 380 patients in each group were identified. At baseline, 359 patients had moderate TR (94.5%) and 21 (5.5%) had severe TR. On the last follow-up echocardiogram, TR had improved in 40.5% of the patients in the significant TR group. Kaplan-Meier survival curves showed significantly lower survival in patients with significant preoperative TR compared to those with nonsignificant TR (P < .001). After adjusting for other confounders, survival was no worse in the patients with significant TR group (hazard ratio, 1.05; 95% confidence interval, 0.80-1.38; P = .70). CONCLUSIONS: Significant preoperative TR improved in 40.5% of patients after isolated CABG. After adjusting for other factors, significant TR did not affect long-term survival.
RESUMO
BACKGROUND: Aiming at fostering local development of cardiology and cardiovascular surgery centers in developing countries, the nonprofit organization Children's HeartLink (CHL) encourages centers to participate in the International Quality Improvement Collaborative Database for Congenital Heart Disease (IQIC). The definition of parameters and data to evaluate patient treatment provides an opportunity to improve quality of care, reducing morbidity and mortality. The objective of the study was to analyze the outcomes of the partnership between CHL and IQIC database with a single pediatric cardiology and cardiovascular surgery center for seven years providing continuous follow-up to guide actions aiming at morbidity and mortality reduction in patients with pediatric and congenital heart diseases. METHODS: Data were collected from January 2011 to December 2017 independently and with external audits and included preoperative information (demographic data, nutritional status, chromosomal abnormalities), Risk Adjustment for Congenital Heart Surgery (RACHS-1) score, and postoperative information such as infections or complications within the first 30 days or until hospital discharge and/or death. RESULTS: In the preoperative period, there was a trend toward an increase in the number of newborn patients. The postoperative period showed significant surgical procedure variations between groups for RACHS-1 risk category ( P = .003), prevalence of risk categories 2 and 3, and an increase in risk categories 4, 5, and 6, mainly in the last two years. Decreases in surgical site infection ( P = .03), bacterial sepsis, and other infections (both P < .001) were observed. At the 30-day postoperative follow-up, there was a decrease of in-hospital ( P = .16) and 30-day ( P = .14) mortality. CONCLUSION: The partnership between CHL and this seven-year analysis of IQIC database demonstrated structural and human flaws, whose resolution led to significant decrease in infection and reduction in mortality despite an increase in the complexity of our pediatric and congenital heart disease population.

Congenital mitral valve malformations are rare, but are well known and described entities. Mitral valve malformations involve mitral valve apparatuses (leaflets and annulus) and subvalvar apparatuses (chordae and papillary muscle). Case reports of accessory mitral leaflets were already described, but were usually an appendix of the normal valve. We describe here a case report and present the images of a trileaflet mitral valve sustained by three papillary muscles in a young girl with subaortic stenosis.
