Abstract:
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.
