Key result
Transatrial transcatheter valve-in-valve implantation was successfully performed in 3 high-risk patients with bioprosthetic mitral valve dysfunction, with all patients discharged in satisfactory condition.
Case Report (n=3)
Transatrial transcatheter valve-in-valve implantation appears to be a feasible and successful approach for high surgical risk patients with bioprosthetic mitral valve dysfunction.
May support transatrial access in select high-risk mitral cases; leaves open durability, safety, and need for prospective trials.
We present three cases of successful transatrial transcatheter valve-in-valve implantation in patients with bioprosthetic mitral valve dysfunction. Patients with a high surgical risk, with severe heart failure due to bioprosthetic mitral valve dysfunction, were implanted with transcatheter prostheses using the transatrial approach. Transesophageal echocardiography and fluoroscopy-guided transcatheter mitral prosthetic valve positioning was performed. With a cardiac pacing at 180 bpm, a transcatheter valve was implanted. The transcatheter valves functioned properly after surgery. The patients were discharged in satisfactory condition.
