title: Coronary sinus compression as a sign of cardiac tamponade.
abstract: Coronary perforation and resultant cardiac tamponade are well-known but rare complications of percutaneous coronary interventions. We present a case that demonstrates coronary sinus compression caused by increasing pericardial pressure as a new sign of impending cardiac tamponade. This previously unreported angiographic sign preceded hemodynamic, symptomatic, and echocardiographic evidence of tamponade.
