Abstract
Pulsus alternans is typically found in patients with left ventricular systolic dysfunction. We describe a woman with biventricular systolic dysfunction and pulsus alternans in the right ventricle, pulmonary artery, and aorta. Coronary angiography revealed an intermediate stenosis in the proximal left anterior descending (LAD) coronary artery. Pulsus alternans was demonstrated in the mid LAD using a 0.014" guidewire-mounted pressure sensor. An abnormal fractional flow reserve was measured in the LAD. Cathet. Cardiovasc.
