Eductional Objective: Due to an abrupt restriction in ventricular movement during passive ventricular filling in diastole, a third heart sound (S3) develops. An S3 in individuals older than 40 implies aberrant ventricular cavity expansion, such as that seen in dilated cardiomyopathy, chronic severe mitral regurgitation, or chronic aortic regurgitation.
