The causes of TR are divided into hereditary and acquired; and also primary and secondary. Primary TR refers to a defect solely in the tricuspid valve, such as infective endocarditis ; secondary TR refers to a defect in the valve as a consequence of some other pathology, such as left ventricular failure or pulmonary hypertension .
The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an overload in chronic pressure.
This causes pulmonary edema and pleural effusions. [34] In the absence of pulmonary blood vessel narrowing, the increased back pressure is described as 'isolated post-capillary pulmonary hypertension' (older terms include 'passive' or 'proportionate' pulmonary hypertension or 'pulmonary venous hypertension').

Right atrial pressure (RAP) is the blood pressure in the right atrium of the heart. RAP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system.
It is also important to control heart disease risk factors including diabetes, high cholesterol, and high blood pressure. Exercise, pregnancy, and prior health conditions like ASD II can also promote cardiac remodeling, so routine primary care visits are important to distinguish between physiological and pathological atrial enlargement.
Pressure overload may affect any of the four chambers of the heart, though the term is most commonly applied to one of the two ventricles. Chronic pressure overload leads to concentric hypertrophy of the cardiac muscle, which can in turn lead to heart failure , myocardial ischaemia or, in extreme cases, outflow obstruction.
[medical citation needed] RVH is also associated with abdominal obesity, elevated fasting blood glucose, high systolic blood pressure, and fractional shortening of the left ventricular mid-wall. [medical citation needed] Other risk factors for RVH include smoking, sleep apnea, and strenuous activity. These increase the risk of heart and lung ...
