Double-Orifice Tricuspid Valve: A Case Report and Literature Review

Duplication of an atrioventricular valve is a rare congenital anomaly that usually involves the mitral rather than the tricuspid valve (TV). Isolated appearances of a double-orifice TV (DOTV) are extremely rare and in most cases are associated with other congenital anomalies. We report a rare case of an HIV-seropositive male with a DOTV, divided right atrium and Wolff-Parkinson-White syndrome admitted to our hospital with palpitations and dyspnea. After medical therapy, the patient's symptoms were alleviated. We summarized the characteristics of the DOTV and reviewed the literature.

Repairing the tricuspid valve in congenital heart diseases other than Ebstein's

The tricuspid valve is being increasingly recognised as an important safeguard to the heart with congenital heart disease. Both structural anomalies of the valve and functional burdens from other malformations of the right heart can lead to major haemodynamic consequences both upstream and downstream. The indications to surgically intervene on the tricuspid valve are evolving and vary depending on the malformation. The extant surgical techniques and their applications to corresponding frequent congenital anomalies of the tricuspid valve are reviewed.

A double-orifice tricuspid valve associated with a divided right atrium

Right atrioventricular valve duplication is a rare congenital anomaly with only isolated cases of a double-orifice tricuspid valve having been described. This article presents a case of the surgical repair of a double-orifice tricuspid valve associated with a divided right atrium, a ventricular septal defect, and Wolff-Parkinson-White syndrome.
