The Advanced Cardiac Centre at Post Graduate Institute of Medical Education and Research (PGIMER) had successfully performed the TAVI (Transcatheter Aortic Valve Implantation) procedure on two critically ill patients who were diagnosed with aortic stenosis in the last week.
Doctors said that the two patients were high risk candidates for the surgery due to their age. Theywere in their seventies. The procedure was carried out by the teams comprising head of the department Professor Yash Paul Sharma, Dr Parag Barwad, Dr Prashant Panda and Dr Himanshu Gupta from department of cardiology, professor G D Puriand, Dr Banashree Mandal from department of cardiac anaesthesia and professor Shyam KST and Dr Anand Mishra from department of CTVS along with a team of senior residents, nursing staff and technicians.
Aortic stenosis, a condition in which the normal aortic valve gets narrowed that leads to a shorter life expectancy for the patient. In this procedure, a catheter with a balloon at its tip is inserted into an artery either in the groin or under the collarbone. It is then passed into the heart and positioned within the opening of the aortic valve.
Dr Yash Paul Sharma said that surgery is the treatment of choice for this disease but many patients are not candidate for surgery due to high risks of mortality. In such patients TAVI is the treatment of choice as it is carried out through blood vessels without the need for surgery. These two patients were satisfactorily worked up before surgery and haemoglobin was maintained at around 15 gm per cent before the procedure for best results.
Doctorsstated while explaining the procedure, that there are two types of valves commercially available. One is the self-expanding type and the other is the balloon expanding valve type. Both these valves were implanted in these two patients.
Dr. Paul said that with this procedure PGIMER department of cardiology has become among the very few centres which can perform this highly demanding and skilled procedure. Their department of cardiology has the least mortality in patients with heart attack and with heart failure. The patients were discharged after two days of the procedure.Doctors said that the first implantation was performed in 2002 on April 16 by Dr Alain Cribier in France and has been commercially available for use in USA since 2011.
