About this person
He is known for being the first to successfully perform a cardiac surgery - specifically, a procedure on the pericardium, the double-layered, fluid-filled sac that encloses the heart and the roots of the great vessels. The pericardium anchors the heart, protects it from infection and trauma, and reduces friction during its constant beating by providing lubrication.
