“…Only one previous group [24] reported persistent defects at rest, but these abnormal regions were randomly distributed. To the best of our knowledge, there have been no reports of a specific region of malperfusion, although resting abnormalities in wall motion using first pass radionuclide angiography have been recently reported [25], and abnormal wall motion on ventriculography in patients with mitral valve prolapse has been described in the past [6,. More recently, abnormal motion of the left ventricular posterior wall on M-mode echocardiography has been reported in patients with mitral valve prolapse [33], and cross-sectional echocardiography has also recently been reported to show abnormal posterolateral basal wall motion in these patients [34].…”

Twenty-four patients with mitral valve prolapse underwent cardiac catheterization, exercise testing, and exercise 201thallium scintigraphy. Of 10 patients with coronary artery disease, six had abnormal scintigrams. Two of these six had exercise-induced reversible defects, two had defects that persisted during redistribution, and two had both reversible and persistent defects. Of 14 patients with normal coronary arteries, five had negative scintigrams. Of the remaining nine patients, two had exercise-induced defects, and seven (50%) had defects involving the inferior or posterior wall that persisted during redistribution. Possible mechanisms for this latter finding are discussed. In contrast to previous reports, exercise 201thallium scintigraphy was not entirely successful in identifying patients with coronary artery disease in our patients with mitral valve prolapse.

“…Echocardiography was performed in the left lateral position using commerically available equipment with a 2. 25 MHz medium internally focused transducer. The study was performed from the standard interspace, and care was taken to avoid inferior angulation of the transducer.…”
