ABSTRACT

The authors describe the experience with surgical treatment of 42 patients with ventricular septal rupture (VSR) in post acute myocardial infarction (AMI). They showed increased mortality in patients with cardiogenic shock (66.6%) with respect to others (9.5%). Sudden descompensations in patients hemodinamically stable were indications to early surgeries, if possible when the diagnosis of ventricular septum rupture (VSR) was made. The compromise of multiple coronary arteries and advanced age were considered as aggravating factors in the prognosis of surgery. The same prognosis did not occur regarding pulmonary/systemic flow and shunt E-D. The technique of exposure in both ventricular cavity and reinforcement in the both sides of the ruptured septum with biological tissue offered good results in the correction of posterior VSR.

RESUMO

Os autores descrevem sua experiência com o tratamento cirúrgico de 42 pacientes portadores de comunicação interventricular (CIV) pós infarto agudo do miocárdio (IAM). Destacam a elevada mortalidade cirúrgica nos pacientes com choque cardiogênico instalado (66,6%) em relação aos demais (9,5%). A observação de descompensações súbitas em pacientes hemodinâmicamente estáveis tem levado à indicação cirúrgica precoce, se possível, assim que estabelecido o diagnóstico da rotura do septo interventricular (RSI). O comprometimento de múltiplas artérias coronárias e faixas etárias elevadas foram considerados fatores agravantes no prognóstico cirúrgico. O mesmo não ocorreu com a relação fluxo pulmonar/sistêmico e shunt E-D, que não guardaram relação com a mortalidade. A técnica de exposição de ambas as cavidades ventriculares e reforço das 2 faces do septo roto com tecido biológico tem fornecido resultados gratificantes na correção da RSI, especialmente de localização posterior.
