For TAVR, you will be hospitalized and doctors will check on your health condition and go through your medical records before initiating the TAVR treatment. TAVI CT Scan is done to size the valve and also to size the groin vessels. Depending on the health condition of the patient, the concerned doctor will give a sleeping dose or mild anaesthesia to keep them awake without the experience of any pain. During TAVR, the heart beats regularly unlike the traditional surgery because of which the heart is kept at pause for sometime and an artificial machine is kept to function like the heart.
