Internal cardiac defibrillator (ICD) is a device that is inserted within the body. It is designed in a way to recognize certain types of abnormal heart rhythms also called as Arrhythmias and thus correct them. Defibrillators continuously monitor the heart rhythm in order to detect Arrhythmias such as Ventricular tachycardia that is the rapid regular beating of the ventricles and Ventricular fibrillation that is the rapid irregular beating of the ventricles.
Percutaneous Aortic Valve Replacement (PAVR) is a new technology used for treatment of aortic valve disease. There are cases where the heart’s aortic valve becomes narrowed thus preventing it from opening properly. This in turn blocks the blood flow from the left lower chamber of the heart to the aorta. In order to maintain the normal blood flow percutaneous aortic valve replacement is done. Percutaneous aortic valve replacement is a minimally invasive procedure that is performed to correct severe aortic stenosis.
Thallium or cardiolite scanning is a diagnostic technique that uses a radioactive isotope or a tracer to evaluate the amount of blood reaching different parts of heart. These are included in the category of nuclear medicine scans.
