Tricuspid valve prolapse

Introduction

Introduction Tricuspid prolapse is due to lesions in the underlying valve or underlying petal that cause the atrioventricular valve (mitral and tricuspid) to detach into the atria during systole, or the semilunar valve (aortic and pulmonary valves) during diastole A clinical phenomenon of detachment into the ventricular outflow tract. It can be divided into two types: primary and secondary. The former is unknown, and the latter can be caused by multiple causes. The disease can occur in any valve, of which mitral valve prolapse is the most common, followed by aortic valve prolapse, and tricuspid and pulmonary valve prolapse is less common.

Cause

Cause

The causes of valvular heart disease are congenital and acquired.

Congenital: valvular lesions have been found at birth. For example, some patients have only two leaves of aortic valve, one leaf less than normal, and the aortic valve of the lesion is incomplete, affecting blood circulation.

Acquired: It is caused by infection, degeneration and other diseases.

A. Infection: Bacteria reach the inside of the heart through the blood and invade the valve. Drug users who use intravenous injections and those who have problems with the valve (thicker or calcified) are more likely to occur.

B. Degeneration: As the age progresses, the valve gradually degenerates, with the aortic valve being the most common.

C. Other: mainly refers to rheumatic heart disease. Due to streptococcal infection, an immune response is triggered to destroy the heart valve.

According to the typical murmur, the right ventricle enlargement of the right atrium and the symptoms and signs of systemic congestion are generally not difficult to make a diagnosis. Echocardiography and Doppler ultrasonography can confirm the diagnosis and help to diagnose the cause.

Ultrasound Doppler imaging is the application of ultrasonic Doppler effect, from the body to obtain information on the human body movements for processing and display. It is now widely used for examinations in blood flow, heart and obstetrics.

Diagnosis

Differential diagnosis

Most of them are a valve prolapse, and a few can also have more than 2 valve prolapses at the same time. Clinically, without or with valvular insufficiency, such as with valvular insufficiency, atrioventricular valve prolapse can hear systolic murmurs and non-ejection clicks in the corresponding auscultation area; prolapse of the semilunar valve can be A diastolic murmur is heard in the corresponding auscultation area. The significance of valve prolapse is that severe cases can cause progressive valvular regurgitation, spontaneous chordae rupture, infective endocarditis, sudden death, and transient ischemic attack.
