###Human: Is there any risk in repeated open heart surgery? ###Assistant: Hello. I have thoroughly gone through your case and can well understand your genuine health concerns. Transthoracic aortic valve replacement (TAVR) is usually considered as a good choice for patients who are not a good candidate for open heart surgery. It is a good alternative for patients based on clinical evaluation and severity of the disease. Every procedure has its own risk factors and the same to TAVR and open heart surgery. It includes heart musculature rupture, valvular damages, some damage to the vessels coming out and going into the heart. Damage to the brain and other major organs due to clot or thrombus formation may also occur due to manipulation and surgery. But in modern day techniques, there are least complications and the benefits outweigh the risks for sure.
