[Prolapse of the mitral valve in coronary heart disease (author's transl)]
Insights
Mitral valve prolapse occurs in 8.5% of patients with myocardial infarction or angina. Most cases lead to mitral insufficiency, impacting cardiac function.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Myocardial infarction and angina pectoris are significant cardiovascular conditions.
- Mitral valve prolapse is a potential complication affecting cardiac function.
Purpose of the Study:
- To investigate the prevalence of mitral valve prolapse in patients with myocardial infarction or angina.
- To determine the incidence of mitral insufficiency secondary to mitral valve prolapse in this patient cohort.
Main Methods:
- Analysis of 200 angio-cardiograms from patients diagnosed with myocardial infarction or angina pectoris.
- Exclusion of patients with rheumatic heart disease.
- Detailed examination of left ventricle and coronary vessels, including pressure measurements.
Main Results:
- Mitral valve prolapse was identified in 8.5% of the analyzed patient group.
- Two-thirds of patients with mitral valve prolapse subsequently developed mitral insufficiency.
Conclusions:
- Mitral valve prolapse is a notable finding in patients presenting with myocardial infarction or angina.
- A significant proportion of these patients develop mitral insufficiency, necessitating further clinical attention.
Abstract:
Two hundred angio-cardiograms of patients with confirmed myodardial infarcts or angina pectoris were analysed. Patients with rheumatic heart disease were not included. In each patient the left ventricule and coronary vessels had been demonstrated and pressure measurements taken. In 8.5% there was prolapse of a mitral valve leaflet. In two thirds of these produced mitral insufficiency.
