Post-myocardial infarction ventricular septal defect: an angiographic study
Insights
Post infarction ventricular septal defect (PIVSD) often occurs within three days of a first myocardial infarct. Preoperative coronary angiography is crucial for selecting patients who may benefit from bypass grafting during septal repair.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Interventional Cardiology
Background:
- Post infarction ventricular septal defect (PIVSD) is a rare but serious complication of myocardial infarction.
- Early diagnosis and appropriate management are critical for improving patient outcomes.
Purpose of the Study:
- To report clinical and angiographic findings in patients with PIVSD.
- To determine the optimal diagnostic and therapeutic strategies for PIVSD.
Main Methods:
- A consecutive series of nineteen patients with PIVSD were studied.
- Clinical data, echocardiography, and coronary angiography were analyzed.
- Surgical repair with or without coronary artery bypass grafting was performed.
Main Results:
- PIVSD complicated a first myocardial infarct in all patients, with over 50% occurring within three days.
- The mean patient age was 65 years, and 63% had single vessel disease.
- Mean left ventricular ejection fraction was 27%; contrast left ventriculography localized the defect in all cases.
Conclusions:
- While cardiac ultrasound confirms PIVSD, preoperative coronary angiography is essential.
- Angiography helps select patients who may benefit from concomitant coronary artery bypass grafting during surgical septal repair.
Abstract:
Clinical and angiographic findings are reported in a consecutive series of nineteen patients with post infarction ventricular septal defect (PIVSD). In all patients PIVSD complicated a first myocardial infarct and none had a history of angina pectoris prior to presentation. In over 50% of the patients PIVSD occurred within three days of infarction. The mean patient age was 65 years. Single vessel disease was noted in 63% of the patients. The mean left ventricular ejection fraction was 27%. Contrast left ventriculography localised the defect in all patients. Although a comprehensive cardiac ultrasound examination will generally confirm the diagnosis of PIVSD, preoperative coronary angiography is essential for the selection of those patients most likely to benefit from concomitant coronary artery bypass grafting at the time of surgical repair of the interventricular septum.
