Landmark-based low implantation using a balloon-expandable valve to avoid sinus sequestration during redo transcatheter aortic valve implantation: a case report

Redo transcatheter aortic valve implantation (TAVI) is increasingly performed for structural valve deterioration of transcatheter heart valves. Sinus sequestration is a mechanism of coronary obstruction in which displaced leaflets of the index transcatheter valve isolate the coronary sinus from the aortic root af...
