Key result
Early diagnosis via emergent coronary angiography and treatment with intracoronary vasodilators and mechanical support successfully reversed life-threatening coronary artery spasm following off-pump coronary artery bypass surgery.

Post-CABG coronary spasm may cause sudden instability; hypothesis-generating from cases and requires prospective confirmation.
Coronary artery spasm after coronary artery bypass surgery may result in life-threatening arrhythmias, circulatory collapse, or death. We report two cases of coronary artery spasm after coronary artery bypass surgery, one of which developed ventricular fibrillation requiring extracorporeal membrane oxygenation support. Both patients were discharged in good condition and are currently followed as outpatients. Unexpected sudden hemodynamic compromise could be due to coronary vasospasm, and this should be considered as one of the possible differential diagnoses. We were able to prevent the lethal consequences seen with coronary artery spasm by early diagnosis and management.

Unai et al. (2014) conducted a case report in Coronary artery spasm following off-pump coronary artery bypass surgery (n=2). Intracoronary vasodilators and mechanical circulatory support was evaluated on Resolution of coronary artery spasm and hemodynamic recovery. Early diagnosis via emergent coronary angiography and treatment with intracoronary vasodilators and mechanical support successfully reversed life-threatening coronary artery spasm following off-pump coronary artery bypass surgery.
