Tricuspid regurgitation (TR), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts .
Tricuspid regurgitation is usually secondary to right ventricular dilation [16] which may be due to left ventricular failure (the most common cause), right ventricular infarction, inferior myocardial infarction, [16] or cor pulmonale [16] Other causes of tricuspid regurgitation include carcinoid syndrome and myxomatous degeneration. [16]
Tricuspid regurgitation: the backflow of blood from the right ventricle into the right atrium, owing to imperfect functioning (insufficiency) of the tricuspid valve. Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve ...
Other recognised causes are: right ventricular failure, tricuspid regurgitation, and atrial septal defect. [1] Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias.
Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
Tricuspid valve stenosis itself usually does not require treatment. If stenosis is mild, monitoring the condition closely suffices. However, severe stenosis, or damage to other valves in the heart, may require surgical repair or replacement. The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty ...
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
