Double-chambered right ventricle (DCRV) is a rare congenital heart disease characterized by the presence of anomalous muscle bundles, which divide the right ventricle into two chambers: a high-pressure proximal chamber and a low-pressure distal chamber. Most DCRV patients are diagnosed and treated during childhood, and presentation in adulthood is not common. Many congenital heart diseases are often associated with other complications such as infective endocarditis (IE). Right-side endocarditis, which usually involves infection of the tricuspid valve, is uncommon, and endocarditis of the pulmonary valve is extremely rare. We report a 51-year-old woman with undiagnosed DCRV and ventricular septal defect associated with pulmonary valve endocarditis. The diagnostic evaluation and the surgical management are discussed.

Isolated absent pulmonary valve syndrome is a very rare entity. We report the case of a four-year-old boy who had congenital absent pulmonary valve with a thin and aneurysmal right ventricular infundibulum. The histological picture was suggestive of Uhl's anomaly. This association of partial right ventricular Uhl's anomaly with absent pulmonary valve syndrome has not been described before. We discuss the embryological and clinical significance of this association. (J Card Surg 2010;25:415-417) [ABSTRACT FROM AUTHOR]

Images related to the case of a 63-year-old male diagnosed with pulmonary artery aneurysm associated with a unicuspid pulmonary valve are presented.

Myxomatous degeneration generally involves the atrioventricular valves (mitral and tricuspid). Rarely, it may affect the aortic or pulmonary valve. We report a case of an acute severe aortic insufficiency due to a rupture of a commissure of the aortic valve in a patient who had previously undergone mitral valve surgery for myxomatous mitral valve prolapse. doi: 10.1111/jocs.12276 (J Card Surg 2014;29:497-498) [ABSTRACT FROM AUTHOR]

Cardiac papillary fibroelastomas (CPF) are benign endocardial papillomas commonly formed from valve endothelium. The majority of tumors are found on the left side of the heart, with only a few case reports of pulmonary valve fibroelastomas. We report here a case of pulmonary valve papillary fibroelastoma that was successfully managed with simple excision of the mass. [ABSTRACT FROM AUTHOR]
