- Science
This series from the Texas Heart Institute at St. Lukes Episcopal Hospital Robert J. Hall Heart Sounds Laboratory presents auscultation of various heart sounds as they relate to the anatomy, physiology, and diagnosis of cardiovascular disease. The podcasts are developed for physicians, medical residents, nurses, and other clinicians who wish to improve auscultation skills. More information that further demonstrates the physiology of the heart sounds is provided for some podcasts. Use headphones for best audio quality.

Ventricular Septal Defect (VSD) Congenital
This podcast examines auscultation of the murmur of congenital ventricular septal defect (VSD). The murmur of congenital ventricular septal defect (VSD) is frequently accompanied by a thrill, and along with the thrill, is best appreciated at the lower left sternal border at the fifth, fourth, and third intercostals spaces.

Hypertrophic Obstructive Cardiomyopathy (HOCM)
This podcast examines auscultation of murmurs associated with hypertrophic obstructive cardiomyopathy (HOCM) and LV outlet obstruction. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Tumor Plop (Left Atrial Myxoma)
A large left atrial myxoma produces a diastolic sound that is referred to as a tumor plop. This sound arises from obstruction to ventricular in-flow that occurs as the tumor comes to rest over the mitral annulus. It is the functional equivalent of mitral valve stenosis and may be associated with a low frequency diastolic murmur. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Pericardial Knock (Constrictive Pericarditis)
The early diastolic sound of pericardial constriction occurs slightly earlier than the average third heart sound. Its frequency is somewhat higher, allowing you to hear it throughout the precordium using the diaphragm and the bell. Common causes of pericardial constriction include prior cardiac surgery and uremic pericarditis. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Fixed Splitting of the Second Sound (ASD)
Auscultation of the fixed splitting of the second heart sound, a finding on physical examination very specific for atrial septal defect. Copyright 2010 by the Texas Heart Institute at St. Luke's Episcopal Hospital.

Wide Splitting of the Second Heart Sound (RBBB)
Auscultation of the wide splitting of the second heart sound, commonly caused by right bundle branch block (RBBB). Copyright 2010 by the Texas Heart Institute at St. Luke's Episcopal Hospital.
