Transcatheter aortic valve replacement for aortic regurgitation secondary to aortic sinus dilation with incidentally detected aortic chordae tendineae: case report

ACT presence does not preclude TAVR but requires meticulous intraoperative surveillance, TEE is critical for detecting these structures and guiding TAVR planning. Precise intraoperative positioning of valve graspers ensures avoidance of ACT-related complications, and rupture of ACT confirmed that it would not compromise prosthetic valve stability in the future. This case supports the feasibility of TAVR in complex aortic root anatomies with incidentally detected ACT.
