What is the medical term meaning the surgical removal of a portion of the tissue surrounding the heart?

A pericardiectomy is the surgical removal of part of the pericardium, the membrane surrounding the heart. Inflammation of this membrane can occur, which is called pericarditis. When pericarditis occurs, the amount of fluid between the heart and pericardium may increase.

This can lead to pain, shortness of breath, and the increased pressure caused by the trapped fluid may disrupt the heart's pumping action. Surgical removal of part of the pericardium, called pericardiectomy, is necessary to release this fluid build up.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
