Abstract

Cardiac catheterization is a commonly performed procedure in the field of cardiology for diagnostic and therapeutic purposes. While it is generally considered safe, there can be rare instances of unexpected complications. Cardiac tamponade, a life-threatening condition characterized by fluid accumulation in the pericardial space, is one such complication. This article presents a case of an unusual cause of cardiac tamponade during a cardiac catheterization study. The case involves a rare congenital anomaly known as a sinus of Valsalva aneurysm, which led to tamponed following inadvertent catheter wire perforation. The prompt recognition and management of this rare complication were crucial in preventing further deterioration and adverse outcomes. This case serves as a reminder of the importance of vigilance and prompt action during cardiac catheterization procedures, highlighting the need for clinicians to be aware of potential rare causes of cardiac tamponed.
