Insights
Prompt surgical repair of left ventricular free wall rupture after acute myocardial infarction can yield good long-term survival, despite high initial hospital mortality. Early diagnosis and assessment of infarct size are crucial for successful outcomes.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Myocardial Infarction Complications
Context:
- Left ventricular free wall rupture is a life-threatening complication of acute myocardial infarction.
- Prognosis is heavily influenced by diagnostic speed, infarct size, and surgical intervention timeliness.
Purpose:
- To evaluate the efficacy and long-term outcomes of emergency surgical repair for left ventricular free wall rupture.
- To analyze factors influencing survival rates in patients undergoing surgical treatment.
Summary:
- Twenty-one patients with left ventricular free wall rupture underwent emergency surgery between 1984 and an unspecified date.
- Surgical techniques involved myocardial resection and repair using reinforced sutures or patching materials, with associated cardiac procedures performed as needed.
- Hospital mortality was 33%, with prolonged postoperative courses requiring intensive care and support in several patients.
Impact:
- Despite high hospital mortality, surgical repair in emergency settings can achieve satisfactory long-term survival.
- Prompt diagnosis via echocardiography and accurate infarct size assessment are critical determinants of successful surgical outcomes and patient survival.
Abstract:
Left ventricular free wall rupture is a catastrophic complication of acute myocardial infarction and prognosis will depend on the prompt diagnosis by echocardiography, extension of infarct size and prompt surgical treatment. From november 1984, 21 patients (14 M, 7 F, mean age 68.4 +/- 6 years) underwent emergency operation at our Institution. Surgical technique included resection of necrotic or scarred myocardium and repair by Teflon strips-reinforced sutures, or by patching with Dacron or autologous pericardium. Associated procedures were LV aneurysmectomy, CABG, LV endoaneurysmorraphy and mitral valve replacement. Hospital mortality was 33% (7/17 pts). The postoperative course was prolonged in one patient, who needed hemodialysis and in 5 patients who needed IAPB counterpulsation. The mean length of stay in UCI was 3-10 days. Mean follow up is 70.4 +/- 41 months and 3 patients died of non cardiac related death. We conclude that despite high hospital mortality, satisfactory results may be obtained by surgical repairy under emergency condition, with good-long term survival, depending on prompt diagnosis and infarct size extension.
