What is a TAVR? (Also called TAVI)This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).Valve-within-valve — How does it work?Somewhat similar to a stent placed in an artery, the TAVR approach delivers a fully collapsible replacement valve to the valve site through a catheter.Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.How is TAVR or TAVI different from the standard valve replacement?This procedure is fairly new and is FDA approved for people with symptomatic aortic stenosis who are considered an intermediate or high risk patient for standard valve replacement surgery. The differences in the two procedures are significant. What is involved in a TAVR procedure?Usually valve replacement requires an open heart procedure with a “sternotomy.”, in which the chest is surgically separated (open) for the procedure. The TAVR or TAVI procedures can be done through very small openings that leave all the chest bones in place.A TAVR procedure is not without risks, but it provides beneficial treatment options to people who may not have been candidates for them a few years ago while also providing the added bonus of a faster recovery in most cases. A patient's experience with a TAVR procedure may be comparable to a balloon treatment or even an angiogram in terms of down time and recovery, and will likely require a shorter hospital stay (average 3-5 days).The TAVR procedure is performed using one of two different approaches, allowing the cardiologist or surgeon to choose which one provides the best and safest way to access the valve:Entering through the femoral artery (large artery in the groin), called the transfemoral approach, which does not require a surgical incision in the chestorUsing a minimally invasive surgical approach with a small incision in the chest and entering through a large artery in the chest or through the tip of the left ventricle (the apex), which is known as the transapical approach.Who is a good candidate for this type of valve surgery?At this time the procedure is reserved for those people for whom an open heart procedure poses intermediate risk. For that reason, most people who have this procedure are in their 70s or 80 and often have other medical conditions that make them a better candidate for this type of surgery.TAVR can be an effective option to improve quality of life in patients who otherwise have limited choices for repair of their aortic valve.Specialist for TAVI in Jaipur- Dr Rudradev Pandey

Avoiding winter heart attackAs temperatures start to fall, your risk of a heart attack begins to climb. "Cold weather sometimes creates a perfect storm of risk factors for cardiovascular problems, " says Dr. Rudradev Pandey, a cardiologist with C.K Biral Group of Hospitals JaipurMany of these risks stem from what Dr. Pandey calls a "mismatch between supply and demand." Cold weather can decrease the supply of oxygen-rich blood to your heart muscle. And it can put you in situations that force your heart to work harder; as a result, your heart demands more oxygen-rich blood. Such a mismatch-a smaller supply of oxygen to the heart coupled with a greater demand for oxygen by the heart-sets you up for a heart attack.Below, we summarize some of the many situations that can lead to heart attack during the colder months-and how to minimize them.Risk: OverexertionWinter sometimes causes us to overexert. We walk briskly against a strong wind, Exertion increases the heart's demand for oxygen. "If there's a blockage in a heart artery that reduces blood flow to the heart muscle, supply may not be sufficient to meet the demand, " says Dr Pandey Many of us have blockages we don't know about.Solution: "Be especially careful about exerting yourself outdoors in winter. . I encourage my patients to avoid doing Heavy Exercises, especially if they have risk factors for heart disease, " says Dr. Pandey. Risk factors include smoking, high blood pressure, high cholesterol, diabetes, family history, and obesity. Dr. Pandey urges you to have someone else help in doing Heavy WorkRisk: Cold exposureWhen your body is suddenly exposed to icy temperatures, your blood vessels clamp down.Solution: "Don't head out the door half-dressed. Put on your coat, hat, and gloves in advance, " says Dr. Pandey.Risk: OverheatingWhile it's important to dress warmly in cold weather, it's also important to avoid getting overheated—for example, from physical activity. If you get overheated, your body will need to release the heat. Too much warm clothing may prevent that, causing blood vessels to dilate, which can dramatically lower blood pressure. "When blood pressure drops, it can reduce the heart's blood supply, possibly leading to a heart attack, " says Dr. PandeySolution: Dress in layers. If you start to sweat, remove a layer until you cool down, then replace the layer. Better yet, go inside and take a break.Risk: InfluenzaA bout of seasonal flu can trigger a heart attack in people already at risk for heart disease. The flu causes a fever, which makes your heart beat faster (raising its demand for oxygen). The flu also can cause dehydration, which can reduce your blood pressure (lowering the heart's supply of oxygen). "Again, when demand exceeds supply, it may lead to a heart attack, " says Dr.Pandey.Solution: Try to avoid getting the flu by washing your hands often with soap and water and getting a flu shot. If you do get flu symptoms, such as fever, cough, or body aches, call your doctor and take antiviral medication if it's prescribed. Avoid dehydration by drinking plenty of fluids or eating water-rich foods such as fruit or soup.Wintertime can have a bad influence on your good health habits. The weather may prevent you from exercising regularly. Holiday parties may lead you to consume more calories, more "bad" fats, more salty food, and excessive alcohol.
