Doctors in Apollo Hospitals, Chennai, saved three lives by successfully performing India’s first fourth generation (G4) transcatheter mitral valve repair recently using a technique that allows doctors to grasp flaps called leaflets that open and close once during each heartbeat, simultaneously or independently.

In a media release, the hospital informed that the repair was performed by the senior interventional cardiologist at Apollo Hospital Dr Sai Satish, who is considered a pioneer in heart valve replacement and mitral valve procedures on patients suffering from end-stage heart failure.

The therapy allows for edge-to-edge mitral valve repair and allows doctors to choose clip size based on a patient’s mitral valve anatomy, the statement added.

Speaking about this new technique, Dr Sai Satish said “These patients had sustained extensive damage to their hearts, and were in refractory heart failure in spite of being optimally treated with medication and all other currently available heart failure devices.”

Elaborating that two patients also had aortic valves procedures done previously which had further altered their mitral anatomies, Dr Satish, who has performed the highest number of Transcatheter mitral valve repairs in the country added, “The intractable heart failure coupled with these extreme anatomical challenges would have made it impossible to treat them with any conventional device available today. The ability to independently grasp each valve leaflet allows us to now get surgical-like repair results even in these select complex anatomies.”

Giving details about the patients, Dr Satish said that the first patient was a 69-year-old man with dilated cardiomyopathy and heart function of less than 20% who had a pacemaker installed in his heart in 2007. He was now referred to us for persisting symptoms of heart failure despite receiving treatment and severe mitral regurgitation.

“He had been turned down for any type of surgical intervention including a heart transplant because of multiple co-morbidities and could not have been treated by any of the earlier devices that are available in the market. He had an excellent procedural outcome with almost no residual mitral leak post-procedure and he was discharged with no failure symptoms,” Dr Satish added.

While the second patient was a 73-year-old female, who had a cardiac arrest with multiple histories of surgical interventions including neurosurgery for a brain tumour and received radiation therapy, the third patient, also a 76-year-old lady, was suffering from severe mitral regurgitation, a condition when the blood flows back to the heart as the mitral valve fails to close tightly, he informed.

All the patients have been discharged and remain free of complications after the intervention, Dr Satish further added.
