Abstract:
An 89-year-old woman with paroxysmal atrial tachycardia (AT) was diagnosed with severe atrial functional mitral regurgitation. On transesophageal echocardiography, the mitral regurgitation jet appeared larger during sinus rhythm and smaller during AT. During transcatheter repair of the valve, chronotropic agents were given to induce AT, assisting with leaflet capture.
