We report a case of acute closure of the left main coronary artery, a rare complication of diagnostic cardiac catheterization, treated by emergency stenting prior to aorto-coronary bypass surgery. We suggest encroachment of the Judkins catheter into a calcified left main ostium; with dissection and acute thrombosis of this segment, as the possible mechanism. Clinically, the patient's condition deteriorated to cardiogenic shock and loss of consciousness. Remarkably, there was no angiographic evidence of significant left main coronary artery disease, besides the presence of calcification in the proximal part of the left coronary system and ventricularization of coronary pressure at the time of engagement. We chose to slide quickly the angioplasty guidewire through the left main coronary artery, which allowed prompt mechanical recanalization and rapid restoration of coronary flow, with dramatic clinical and hemodynamic improvement. This relatively simple procedure allowed stenting the left main artery after brief predilation, and the patient came to by-pass surgery in excellent condition. The rationale for surgery in this case was the need for complete coronary revascularization because of significant 3-vessel coronary artery disease.
