Single-photon emission computed tomographic myocardial perfusion imaging in patients with mitral valve prolapse

Am J Cardiol. 2000 Feb 15;85(4):516-8, A11. doi: 10.1016/s0002-9149(99)00786-9.

Abstract

The possibility of exercise-induced myocardial ischemia due to mitral valve prolapse (MVP) in the absence of coronary artery disease was evaluated with single-photon emission computed tomographic analysis using thallium-201 and technetium-99m sestamibi in 72 patients with MVP. Exercise electrocardiography was positive in 5 patients (8%), but single-photon emission computed tomography was found to be normal in all patients, and exercise-induced chest pain, electrocardiographic changes, and arrhythmias were found not to be related to myocardial ischemia in patients with MVP.
