  • Implantable Cardioverter Defibrillator: This is a battery-powered device that is placed under the skin to keep the tracks of your heartbeat rate. Some thin wires that connect to the ICD are attached to your heart. If there is any abnormal heart rhythm that is detected through this device, then an electric shock is delivered to restore the normal heartbeat.

The best heart surgeons perform the following methods to find solutions: Using specialized wires that can make a pathway to pass through the blockage and then perform an Angioplasty to restore the blood flow in the artery. Cardiologists use a procedure called Rotablation to try and restore blood flow by inserting a wire that has a diamond tip drill at its tip. This allows us to compress the air and gradually widens the narrowing and follows is a pathway.
