There are 4 main valves in the heart

1.)   Tricuspid Valve
2.)   Pulmonary Valve
3.)   Mitral Valve
4.)   Aortic Valve

Narrowing of the tricuspid valve is Tricuspid Stenosis

Almost always caused by Rheumatic fever

Other causes include carcinoid syndrome, from birth (congenital), endocarditis, and others

Can cause Atrial Fibrillation

Symptoms
   -    Atrial Fib
   -    Heart murmur [Diastolic]
   -    Ascites
   -    Hepatomegaly
   -    Edema
   -    Right sided heart failure

Echocardiography/Doppler is essential to confirm the diagnosis
Heart Catheterization
ECG – may be beneficial.

Treatment
·         Surgery to replace the valve
·         Balloon valvuloplasty in children or infants to stretch the valve
