Post-myocardial infarction ventricular septal defect: an angiographic study
Irish Journal of Medical Science
|April 1, 1994
Summary
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.
