ABSTRACT
Percutaneous coronary intervention (PCI) is an essential modality for the treatment of coronary artery disease. However, rare complications, such as coronary artery perforation and equipment failure, pose significant challenges. This case report describes a unique case of PCI-related coronary artery perforation and a cascade of subsequent complications managed successfully by an unconventional approach. We present a case of an 86-year-old patient who underwent coronary angiography for unstable angina and was treated with implantation of two drug-eluting stents into his right coronary artery (RCA). Implantation of the second stent caused an Ellis grade III perforation. The attempt to seal the perforation with two covered stents failed, the leak persisted, and a balloon had to be reinflated in proximal RCA. However, the patient descending into obstructive shock abruptly flexed his upper extremities breaking off the inflated balloon in proximal RCA, effectively sealing the perforation. Successful pericardiocentesis with drainage of 250 ml of blood stabilized the patient's condition and he regained consciousness. Despite moderate-intensity chest pain and extensive consultation with members of the heart team, the patient refused cardiac surgery opting for a conservative approach. The patient was discharged on post-PCI day 7, eventually resumed a physically active lifestyle, and returned for frequent follow-up visits. This case highlights the challenges in managing rare PCI complications like coronary artery perforation and balloon shaft fracture. It emphasizes the importance of rapid recognition, discusses individual techniques for the management of these complications, and focuses on the value of shared decision-making.
