[Angiographic mitral regurgitation in patients with chronic ischemic cardiopathy. Coronarioangiographic and ventriculographic correlations (author's transl)].
Mitral regurgitation in patients with chronic ischemic cardiopathy may occur following dysfunction of the papillary muscles and left ventricular impairment. A total of 291 patients with significant coronary lesions and absence of associated cardiopathies are reviewed. Patients were divided into three groups: Group A, formed by 241 cases without mitral regurgitation; group B, including 42 patients with slight mitral regurgitation, and group C, formed by eight patients with moderate or severe mitral regurgitation. Significant differences between groups A and B in relation to the number of affected coronary arteries, inferior or anterolateral akinesia-dyskinesia, and left ventricular enlargement were observed. There were no significant differences between groups B and C, though all patients of the last group had two or three affected coronary arteries. Angiographic mitral regurgitation following chronic ischemic cardiopathy is uncommon, especially moderate or severe degrees of regurgitation. Mitral regurgitation is related to the number of affected coronary arteries, presence of inferior or anterolateral akinesia-dyskinesia, and enlargement of the left ventricle. Clinical signs of significant mitral regurgitation may suggest the existence of coronary lesions, at least in two vessels.
