Tricuspid stenosis

The tricuspid valve is a one-way valve located between the right atrium and the right ventricle of the heart. Blood flows from the right atrium into the right ventricle through the tricuspid valve. If the tricuspid valve cannot open completely, it is called tricuspid stenosis. Tricuspid stenosis is relatively rare, and congenital cases are even rarer. Acquired tricuspid stenosis is often a component of rheumatic heart valve disease, and isolated tricuspid stenosis is uncommon. It is often accompanied by varying degrees of tricuspid regurgitation, as well as mitral and/or aortic valve disease. Clinical symptoms of this disease mainly include fatigue, dyspnea, and ascites, along with jugular venous distension, significant hepatomegaly, and lower extremity edema.

Secundum atrial septal defect

Atrial septal defect (ASD) is a type of congenital heart disease, accounting for 30% of all congenital heart diseases. Secundum atrial septal defect is one type, accounting for approximately 80% of all ASDs. When the defect is located in the central part of the interatrial septum at the fossa ovalis, it is called a central type. In some patients, the defect is located lower, known as a low-lying defect. The progression of secundum atrial septal defect is relatively slow, with most patients developing symptoms in adulthood. Secundum atrial septal defect can occur independently or in conjunction with other intracardiac malformations, such as pulmonary valve stenosis, partial anomalous pulmonary venous drainage, and mitral stenosis.
