Summary
This study investigated mitral valve prolapse in patients with ischemic heart disease and normal coronary angiograms. A significant prevalence of mitral valve prolapse was found in these specific patient cases.
Area of Science:
- Cardiology
- Cardiac Imaging
- Valvular Heart Disease
Background:
- Ischemic cardiopathy with normal coronary arteries presents a diagnostic challenge.
- Mitral valve prolapse (MVP) can occur in various cardiac conditions.
- Understanding MVP prevalence in this specific group is crucial for diagnosis and management.
Purpose of the Study:
- To determine the prevalence of mitral valve prolapse in patients diagnosed with ischemic cardiopathy despite having normal coronary angiograms.
- To investigate the association between ischemic symptoms and MVP in this patient cohort.
Main Methods:
- Retrospective review of coronary-ventriculographic studies from the I.N.C. archives.
- Inclusion criteria: 47 patients with chest angina and/or electrocardiographic changes suggestive of myocardial ischemia, and normal coronary angiograms.
- Left cineventriculography in the right-front oblique position was used to assess for mitral prolapse.
Main Results:
- Out of 47 patients with ischemic cardiopathy and normal coronaries, 30 cases (63.8%) showed strong evidence of mitral valve prolapse.
- The diagnosis of MVP was based on findings from left cineventriculography.
Conclusions:
- Mitral valve prolapse is highly prevalent in patients presenting with ischemic heart disease features but normal coronary angiograms.
- These findings suggest MVP should be considered in the differential diagnosis for patients with unexplained ischemic symptoms and normal coronary arteries.
