Recurrent cardiac tamponade following unusual micro leak after successful closure of the primary leak.

Although uncommon, coronary artery perforation is one of the most dreadful complications of percutaneous coronary intervention, which requires prompt, aggressive, and effective management. Perforations induced by coronary guidewires are usually located in the distal part of a coronary artery and commonly managed with embolization. This is an unusual case report of guidewire-induced coronary perforation with recurrent cardiac tamponade, which was managed successfully by coil embolization of both ipsilateral and contralateral coronary arteries via transradial approach.
