Transcatheter aortic valve replacement planning with cardiac computed tomography in quadricuspid aortic valve stenosis: a case series.

ABSTRACT:

Background

The presence of severe aortic stenosis in quadricuspid aortic valve (QAV) is an extremely rare combination, and it is unknown whether transcatheter aortic valve replacement (TAVR) is a safe option due to the low incidence.

Case summary

We present two patients diagnosed with severe aortic stenosis with QAV morphology type 1 (Nakamura classification). All patients presented to our hospital for evaluation because of worsening functional class, dyspnoea, or syncope. During tomographic planning, the aortic annulus was measured at the level of the deepest sinus for the selection of the number of devices. Due to the presence of four cusps, the smallest cusp was excluded, and three sinuses were virtualized for placement of the pigtail catheter during the procedure. Withou
