affects the upper chambers (atria) of the heart. In AF, the atrium quivers instead of beating normally. AF can also lead to rapid heart rhythm, where the heart can beat as much as 300 times a minute or more in the atria and up to 150 times a minute or more in the lower chambers (ventricles). Those with AF have a five-time greater risk of stroke and two times greater risk of heart failure than those with normal heart rhythms. About Cryo balloon Ablation Technology, Dr AM Karthigesan, a Senior Consultant Cardiologist & Electrophysiologist at the Apollo Main Hospitals, Chennai stated that "Cryo balloon Ablation” for AF is a new interventional procedure that is employed to control heart rhythms that are caused by abnormal electrical signals travelling from the pulmonary veins to the atria. An inflatable balloon that uses cold energy to remove heat from the tissue and disable unwanted electrical signals by creating a circle of scar tissue (also known as a lesion) around the pulmonary veins. A small incision in the groin area to insert the catheter to access the left atrium (upper chamber). The balloon is inflated and moved to the opening of the pulmonary vein, plugging the opening temporarily so the balloon is able to reach a cold enough temperature. The Cardiac Electrophysiologist then introduces cold energy (nitrous oxide) into the balloon. The cold energy freezes the tissue where the balloon touches the opening of the pulmonary vein. This scars the tissue, stopping the transmission of electrical signals that cause atrial fibrillation. Early ablation treatment with Cryo Balloon gives better quality of life and reduces the risk of heart failure and stroke in AF patients. According to Dr A.M.Karthigesan, Apollo Hospitals has been bringing new life-saving services and procedures to the people to improve their health and wellness. This new procedure is another reminder of that commitment.
