The aortic valve usually opens when blood is pumped from the heart to the rest of the body. In aortic stenosis, the valve cannot open and close properly. This results in extra pressure on the heart and leads to breathlessness, swollen ankles, chest pain, dizziness and blackouts.
Aortic stenosis (AS) affects 2% of the adults over 65 years and 12.4% for those above the age of 75, the overall prevalence of aortic stenosis is known to increase with age. . 50% of AS patients presenting with heart failure and chest pain are found to live for 2 and 5 years respectively, if not treated with aortic valve replacement (AVR). 
“Transcatheter aortic valve replacement or TAVR is preferred when it comes to treating patients aged above 60 – 70years. TAVR procedure replaces a diseased aortic heart valve through a minimally invasive procedure, without open-heart surgery and without surgical removal of the diseased valve. The device is typically inserted via an artery in the leg and then guided through the arteries into the heart. Once in place, the device expands and takes over the original valve’s function to enable oxygen-rich blood to flow efficiently out of the heart”, said Prof. Dr. Ranjan Shetty, Senior Interventional Cardiologist, Manipal Hospitals, Bangalore and Former Head of Cardiology Department, Kasturba Medical College, Mangalore.
In the month of February 2017 a 79 year old gentleman with background history of diabetes, hypertension and with compromised kidney function was diagnosed with 70% aortic stenosis and had to be admitted to a hospital urgently. He was also suffering from heart failure and swelling in lungs leading to breathlessness. He was later shifted to Manipal Hospital on a ventilator support. “He was diagnosed with multiple blockages in heart vessels too. At this point considering severe aortic stenosis and multi vessel disease, we evaluated the option of bypass surgery with aortic valve replacement and discharged the patient. However he was readmitted within few days with complaints of severe breathlessness again. In view of his heart failure, kidney failure and Aortic Stenosis, open heart surgery would have involved very high risk. Then there was also his age factor that had to be considered along with medical history we started is treatment by first implanting a stent to treat the blocked arteries. This was important procedure to improve blood supply to heart vessels. Four days later, we performed the TAVR procedure. Procedure was successful with no obstruction in blood flow through aortic valve. Heart’s pumping ability also showed improvement. The end result was positive with improved symptoms and quality of life”, said Prof. Dr.Ranjan Shetty, Senior Interventional Cardiologist, Manipal Hospitals, Bangalore and Former Head of Cardiology Department, Kasturba Medical College, Mangalore.
“Patients who undergo a minimally invasive TAVR procedure may experience less down time, faster recovery and, often, a shorter hospital stay -3- to 5 days on an average compared to patients undergoing open heart surgery. TAVR is the first-line therapy for inoperable and high risk patients with severe aortic stenosis. We are happy to have access to the latest advancements in medical technology and are able to offer world class therapies to our patients,” said Prof. Dr. Ranjan Shetty, Senior Interventional Cardiologist, Manipal Hospitals, Bangalore and Former Head of Cardiology Department, Kasturba Medical College, Mangalore.
