Complex PVL After Self-Expanding TAVI by Dr. Andrew Ho

Описание: This 60-year-old patient previously underwent TAVI with a self-expanding valve for a congenitally bicuspid aortic valve with heavy calcification. He was referred with a paravalvular leak (PVL) for device-based closure.

👇👇👇

The challenge was a V-shaped calcium spur that prevented full valve expansion, leaving a narrow leak channel between the valve and the native annulus.

Key anatomical findings included:

✴ Good apposition along most of the valve perimeter
✴ A tunnel-like leak cavity on the posterior aspect
✴ Two possible entry points for occluder device access
✴ Difficulty appreciating the geometry on traditional 2D views

This 3D simulation explores:

✴ The relationship between calcification and valve expansion
✴ The leak pathway and potential occluder orientation
✴ The challenges of PVL device deployment in calcified anatomy
