Ventricular septal rupture is a new opening in the septum between the two ventricles.It creates a harsh,holosystolic murmur that is loudest (by auscultation)along the left sternal border.Papillary muscle rupture is auscultation of a new,high-pitched,holosystolic,blowing murmur at the cardiac apex.Tricuspid stenosis is a quiet murmur that becomes louder with inspiration and is located in the epigastrium area.A pericardial friction rub is a sound that can occur within 2 to 7 days after a myocardial infarction.The friction rub results from pericardial inflammation (pericarditis).Classically,a pericardial friction rub is a grating or scratching sound that is both systolic and diastolic,corresponding to cardiac motion within the pericardial sac.
