Cardiac tamponade secondary to ventricular wall perforation is one of the possible complications of right-sided as well as left-sided cardiac catheterization. Ventriculography was performed on a patient with obstructive cardiomyopathy using a nonionic contrast medium.
During the procedure, the right ventricle was accidentally perforated and the patient developed cardiac tamponade. Pericardiocentesis was unsuccessful and surgical drainage was needed after the patient developed progressive hemodynamic deterioration.
At surgery, pericardial thrombus was found.
We consider the reason for failure of pericardiocentesis was rapid coagulation of the extravasated blood in connection with nonionic contrast material.
