Document Summary
Hans had a strep throat two weeks before he was to start a new job. He had to complete some work before he could resign from his old position so he ignored the bacterial infection. In the first week of his new job he noticed he felt weak and short of breath. An ecg revealed an enlarged p (representing atrium) wave. Hans may well have mitral valve stenosis, based on this ecg finding. The physician may hear a heart murmur caused by the turbulence of the blood as it flows through the scarred bicuspid valve. A type of valvular stenosis which is a type of valvular insufficiency: failure of valve to prevent back flow of blood usually because the cusps are stiffened and the opening is constricted by scar issue. If opening is constricted, then the heart has to work harder to plush blood through openings and may become enlarged.
