Intending to find out which is the prevalence of mitral valvular prolapse in cases of ischemic cardiopathy with "normal" coronariography, a review was made of the coronary-ventriculographic studies at the I.N.C. archives, which showed as clinical diagnosis that of ischemic cardiopathy with "normal" coronaries. In the present studies we record 47 cases showing chest angina and/or electrocardiographic changes in rest or effort tests, compatible with myocardic ischemia and coronariography undoubtedly normal. We found 30 cases (63.8%) showing strong evidence of mitral prolapse in the left cineventriculography taken in right-front oblique position.
