Chronic Ovine Model of Right Ventricular Failure and Functional Tricuspid Regurgitation

Right ventricular failure and functional tricuspid regurgitation are associated with left-sided heart disease and pulmonary hypertension, which contribute significantly to morbidity and mortality in patients. Establishing a chronic ovine model to study right ventricular failure and functional tricuspid regurgitation will help in understanding their mechanisms, progression, and possible treatments.

Cardiac Exam III: Abnormal Heart Sounds

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center Having a fundamental understanding of normal heart sounds is the first step toward distinguishing the normal from the abnormal. Murmurs are sounds that represent turbulent and abnormal blood flow across a heart valve. They are caused either by stenosis (valve area too narrow) or regurgitation (backflow of blood across the valve) and are commonly heard as a "swishing" sound during auscultation.

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center Proficiency in the use of a stethoscope to listen to heart sounds and the ability to differentiate between normal and abnormal heart sounds are essential skills for any physician. Correct placement of the stethoscope on the chest corresponds to the sound of cardiac valves closing. The heart has two main sounds: S1 and S2. The first heart sound (S1) occurs as the mitral and tricuspid valves...

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
FAQs
Changes in intensity, timing, or character provide clues about altered cardiac sound production and hemodynamics. They may reflect differences in valve closure, blood flow, or turbulent flow near the right side of the heart. Because these findings are not interpreted in isolation, clinicians compare them with other auscultation observations during a focused cardiovascular assessment.
Sound vibrations reaching the chest wall can arise from tricuspid valve closure, moving blood, or turbulent flow. The stethoscope detects these vibrations at the lower left sternal border, where they can be assessed by their intensity, timing, and character. Evaluating these qualities helps connect an audible finding with possible changes in underlying hemodynamics.
This landmark provides access to sounds produced by the tricuspid valve and adjacent right-sided heart structures. Abnormal findings can therefore support evaluation of conditions involving right-sided circulation, including tricuspid regurgitation, tricuspid stenosis, and right-sided heart strain. The examination offers focused information about hemodynamics without replacing assessment of the other cardiac auscultation areas.
The clinician places the stethoscope at the lower left sternal border, using the fourth or fifth intercostal space as the examination location. Sounds are then assessed for their intensity, timing, and character rather than merely noted as present or absent. These observations are incorporated into the broader cardiovascular examination and compared with findings from other valve areas.
Focused auscultation can contribute to the clinical evaluation of tricuspid regurgitation and tricuspid stenosis, as well as right-sided heart strain. It may also support assessment of selected congenital or pulmonary conditions when these affect relevant cardiac findings. The landmark is therefore useful as one component of a targeted cardiovascular assessment rather than as a standalone diagnostic test.
Auscultation at this location samples sounds from the tricuspid valve and nearby right-sided structures, but cardiovascular assessment depends on integrating findings from multiple landmarks. Comparing sound qualities across valve areas helps place a change in intensity, timing, or character into a broader clinical pattern. This combined approach strengthens focused evaluation of abnormal hemodynamics and related conditions.
