Echocardiography‐Guided Pacemaker Programming Can Improve Cardiac Hemodynamics in Patients Undergoing Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement ( TAVR ) is an effective treatment option for patients with severe aortic stenosis who are at high surgical risk because of multiple comorbidities. Many of these patients have been treated with pacemakers for concomitant conduction disease. The combination of severe aortic stenosis, cardiomyopathy, and conduction abnormalities results in a state of low cardiac output. Here, we report 2 complex TAVR cases where Doppler echocardiography was used to guide adjustment of device settings, leading to improved cardiac hemodynamic profiles.
