Malfunction of tricuspid valve prosthesis shown by isotope angiocardiography
AD Malcolm, SP Ahuja and MJ Chamberlain
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.
