Key result
Perforation of a distal right coronary artery collateral during chronic total occlusion recanalization resulted in a left atrial intramural hematoma with circulatory collapse in 1 patient.
Case Report (n=1)
Highlights a rare, life-threatening complication of CTO recanalization and the critical role of prompt TEE and surgical intervention.
Raises awareness of rare catastrophic complication during CTO PCI; leaves open optimal prevention and management strategies.
We describe a rare complication of a complex chronic total occlusion recanalization procedure. Perforation of a distal right coronary artery collateral results in a left atrial intramural hematoma with consequent circulatory collapse. Access to prompt transoesophageal echocardiography and urgent surgical intervention were lifesaving and the case highlights possible implications on the planning of complex chronic total occlusion recanalization procedures.

Franks et al. (2014) conducted a case report in Chronic total occlusion (n=1). Chronic total occlusion recanalization was evaluated. Perforation of a distal right coronary artery collateral during chronic total occlusion recanalization resulted in a left atrial intramural hematoma with circulatory collapse in 1 patient.
