Abstract

To examine the relation between papillary muscle fractional shortening and heart shape, we performed quantitative echocardiography in 20 patients with prior myocardial infarction and 20 normal control subjects. Papillary muscle fractional shortening was markedly depressed in infarction patients and there was a high degree of correlation between papillary muscle fractional shortening and left ventricular shape, which was evident over a wide range of ejection fraction and shape.
