Abstract:
Entrapment of coronary angioplasty hardware is a rare but serious complication of coronary interventions which may be managed percutaneously or surgically. We described a case of an entrapped coronary stent in a patient with a history of failed coronary intervention with no documents available. In transesophageal echocardiography, there was a linear echo density in the ascending aorta stuck in the right coronary artery resembling a dissection flap but based on the history of failed coronary intervention, this odd structure was supposed to be a retained angioplasty device. The patient underwent surgical removal of the entrapped device which was a fractured stent.
