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: 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 ...
This is also known as an "echo" or ultrasound of the heart. [1] It shows the heart structures and blood flow through the heart. Further testing is usually done when symptoms that may be of concern are present. The need for treatment depends on the diagnosis and severity. [1] In some cases, the condition causing the heart murmur may prompt ...
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
Tricuspid regurgitation Intensifies upon inspiration. Can be best heard over the fourth left sternal border. The intensity can be accentuated following inspiration (Carvallo's sign) due to increased regurgitant flow in right ventricular volume. Tricuspid regurgitation is most often secondary to pulmonary hypertension.
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]
Aortic regurgitation, though obvious using echocardiography visualization, usually does not produce an audible murmur. [ citation needed ] Stenosis of the mitral valve, if severe, also rarely produces an audible, low frequency soft rumbling murmur, best recognized by a practiced ear using high quality, especially electronically amplified ...
Since the main causes of right ventricular hypertrophy is tricuspid regurgitation or pulmonary hypertension (discussed above), management involves treatment of these conditions. [3] Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [ 12 ]
