Tricuspid Valve Obstruction Research Articles

Malfunction of tricuspid valve prosthesis shown by isotope angiocardiography

Isotope angiocardiography established prosthetic tricuspid valve obstruction in a patient 6 years after triple valve replacement. Thrombus formation is a common complication of prosthetic cardiac valves, particularly in the tricuspid position where engagement of cage with myocardium is an additional potentially obstructive hazard. Comparison is made between the information yield of the isotope investigation and cardiac catheterization with contrast cineangiography. It is suggested that the isotope technique can noninvasively provide valuable anatomic and functional data, particularly where the right side of the heart is to be examined.

Lymphosarcoma of the Right Atrium

A patient had metastatic lymphosarcoma involving the right atrium and tricuspid valve in which functional tricuspid valve obstruction was relieved by chemotherapy. Patients with disseminated or mediastinal lymphoma in whom cardiopulmonary symptoms occur should be considered for catheterization of the right side of the heart and angiography. These procedures may be useful for determining the presence, location, and nature of cardiac disease and may aid in deciding the proper course of therapy.

Tricuspid and pulmonary valve obstruction relieved by removal of a myxoma of the right ventricle

A 30 year old woman complained of progressive fatigue and was noted to have systolic and diastolic murmurs. At cardiac catheterization, pressure gradients were found across the tricuspid and pulmonary valves. Selective angiocardiography demonstrated a large, mobile right ventricular intracavitary filling defect. Three months after surgical removal of a right ventricular myxoma, no evidence of residual valve obstruction was noted on pressure pullback recordings or cineangiocardiograms, and the cardiac output had doubled. Clinical improvement was good.

Acute tricuspid valve obstruction following the use of tricuspid ball valve prosthesis.

A case is presented in which the mitral and tricuspid valves were replaced by a ball-valve prosthesis. The patient was admitted as an emergency 18 months later with the clinical picture of acute venous inflow obstruction to the heart due to tricuspid ball-valve prosthesis obstruction. Successful replacement under emergency open heart surgery, using assisted circulation, is described.
