Complex TMVR surgery on 56-year-old patient performed successfully at NIMS in Hyderabad

According to NIMS hospital authorities, this was for the first time that in its history that the Cardiology team has managed to conduct a TMVR procedure on the patient, who was suffering from severe mitral stenosis due to Mitral Annular Calcification (MAC)

Hyderabad: The cardiology team of Nizam’s Institute of Medical Sciences (NIMS) on Friday announced that they have successfully performed Transcatheter Mitral Valve Replacement (TMVR) heart procedure on a 56-year-old patient.

According to NIMS hospital authorities, this was for the first time that in its history that the Cardiology team has managed to conduct a TMVR procedure on the patient, who was suffering from severe mitral stenosis due to Mitral Annular Calcification (MAC), which is the narrowing of the mitral valve, the heart valve that controls the blood flow.

The patient, who also suffers from hypertension, diabetes, and chronic kidney disease (CKD) requiring maintenance hemodialysis, was deemed high-risk for a conventional (open heart surgery) surgical mitral valve replacement. Faced with this challenge, the expert cardiology team at NIMS sought alternative, cutting-edge treatment options.

Dr. B. Srinivas, Professor and Head, Cardiology, NIMS led the team of surgeons including Dr. Manikrishna, Dr. Abhinay Reddy, and Dr. K. Anurag and conducted the TMVR procedure on November 19.

The team also employed an advanced technique (LAMPOON) designed to prevent obstruction to blood flow post-implantation by cutting a portion of the native valve.
TMVR is a state-of-the-art, minimally invasive procedure that replaces a diseased mitral valve without the need for open-heart surgery.

Instead, the new valve is implanted via a blood vessel in the leg, ensuring a faster and safer recovery. Performing TMVR in a patient with mitral annular calcification, where excess calcium deposits significantly complicate the process, is exceedingly rare and has only been successfully attempted a handful of times globally.
