Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure. Transthoracic echocardiography revealed… CONTINUE READING
