Summary:In post-AMI VSD latter closure seems to be advantageous but an important bias exists. Overall, it seems that these patients benefit from being operated as late as their hemodynamic profile permits. ▪ We performed a collective analysis of a dedicated national post-myocardial infarction ventricular septal defect (VSD) registry to further elucidate controversial areas of this clinical entity's surgical treatment. A descriptive statistical analysis was carried out and cumulative survival using the Kaplan-Meier method and multivariate logistic regression of risk factors for 30-day mortality are presented. Median survival of the cohort (n=76) was 72 months (95% CI 4–144 months). Better cumulative survival was observed in patients who underwent VSD closure more than 10 days after myocardial infarction (log-rank p=0.036). Concomitant coronary artery bypass grafting (CABG), different closure techniques, location of the VSD, extracorporeal membrane oxygenation as bridge to closure, or intra-aortic balloon pump as bridge to closure showed no statistically significant differences at Kaplan-Meier analysis. Multivariate binary logistic regression for independent factors affecting status at 30 days showed a statistically significant effect of age (OR 1.08; 95% CI 1.01–1.15) and concomitant CABG (OR 0.23; 95% CI 0.06–0.90). Our results are comparable with previous reports regarding mortality, risk factors and concomitant procedures. Timing of surgery remains a controversial issue. Later closure seems to be advantageous, however, there is significant observational bias. Análise coletiva de um registo nacional dedicado a comunicação interventricular (CIV) pós-enfarte (EAM) de forma a elucidar áreas controversas do tratamento cirúrgico desta entidade clínica. Analise descritiva; sobrevida cumulativa utilizando o método de Kaplan-Meier; análise multivariada utilizando regressão logística para fatores de risco para mortalidade a 30 dias. A sobrevida mediana da coorte (n=76) foi de 72 meses (6 anos, 95% CI 4-144 meses). Melhor sobrevida cumulativa foi observada nos doentes submetidos a encerramento cirúrgico da CIV após 10 dias do EAM (log-rank p=0,036). CABG concomitante, diferentes técnicas cirúrgicas de encerramento, localização da CIV, ECMO como ponte para encerramento ou BIA como ponte para encerramento não relevaram diferença estatisticamente significativa na análise de Kaplan-Meier. Análise multivariada para fatores independentemente associados a mortalidade a 30 dias revelou uma diferença estatisticamente significativa da idade (OR 1,08; 95% CI 1-011-15) e CABG concomitante (OR 0,23; 95% CI 0-06-0,90). Os nossos resultados são comparáveis com os resultados previamente reportados por outros autores. O timing do encerramento cirúrgico em relação ao EAM permanece um assunto controverso. No entanto, um encerramento mais tardio parece ser vantajoso, apesar de existir um importante viés observacional.
