Description
Alec G. Miller and colleagues report a 2026 case of a rare shunt after catheter aortic valve replacement, where blood leaked from the outflow tract into the right atrium. A 74-year-old man arrived with worsening heart failure after receiving a balloon-expandable Sapien valve. Catheter pressures showed left-to-right shunting, and gullet ultrasound traced the leak to a Gerbode defect.
The hole was closed through a catheter with an Amplatzer septal occluder, though the device later needed swapping for a leak around its edge. Heavy calcium patterns may predispose to such defects, though predictors remain undefined. Operators should watch for this shunt after valve replacement, since ultrasound diagnosis and catheter closure can spare high-risk patients open surgery.
