Quizplus · Accepted Answer

A split S₁ with an abnormally wide split is pathological.The split is wider than usual during inspiration and is still heard on expiration.In mitral stenosis,the tricuspid valve can close before the mitral valve closes because of calcification of the diseased mitral valve.If the mitral valve closes before the tricuspid valve,it is caused by greater pressure in the left side of the heart.An abnormally split S₁ is not related to the sound of the mitral valve as it closes or opens.
