Abstract:
Reoperative aortic valve replacement is associated with increased morbidity. Valve-in-valve transcatheter aortic valve replacement offers a less invasive alternative to traditional reoperation. However, cases of valve failure after valve-in-valve transcatheter aortic valve replacement represent a complex surgical challenge. We present a case requiring a complex reoperative aortic valve replacement due to structural valve deterioration after multiple previous valve-in-valve transcatheter aortic valve replacements. We performed removal of 3 previous valve-in-valve transcatheter aortic valves, bioprosthetic leaflet excision, and intentional bioprosthetic fracture under direct vision for annular enlargement. This facilitated direct insertion of a new transcatheter aortic valve for expedient and successful management of recurrent aortic stenosis in a very high-risk patient. Creative use of leaflet excision, intentional bioprosthetic fracture, and insertion of a new transcatheter aortic valve under direct vision, proved efficient and successful in a high-risk patient with few surgical options.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
