Left Ventricular Outflow Tract Morphology as a Predictor of Conductance Disturbances Following Transcatheter Aortic Valve Replacement.

ABSTRACT:

Background

Conduction disturbances represent one of the most common complications following transcatheter aortic valve replacement (TAVR). We sought to investigate the role of left ventricular outflow tract (LVOT) morphology in the development of conduction disturbances following TAVR.

Methods and results

Consecutive patients who underwent TAVR in our center were included. The ratio between the LVOT area and the aortic annulus area was calculated. Patients were then divided into 2 groups on the basis of this ratio: group 1, which included patients with an LVOT area/aortic annulus area ratio <0.9; and group 2, which included patients with an LVOT area/aortic annulus area ratio ≥0.9. The primary end point was to assess the relationship between LVOT shape and the rate of perman
