Key Medical Attributions

Rouanet was the first person to state that the first and second heart sounds (S1 and S2) were as a result of the heart valves closing. He wrote in his 1832 MD thesis that first heart sound occurred when the atrioventricular (mitral and tricuspid) valves closed, and the second occurred when the semilunar (aortic and pulmonic) valves closed.
