Case report Angioplasty of the unprotected left main coronary artery stenosis with standby cardiopulmonary support – a case report

Abstract

Stenosis of the unprotected left main coronary artery (LMCA) is a classical indication for coronary artery bypass graft surgery (CABG). Percutaneous coronary intervention (PCI) of LMCA may be an alternative to surgical treatment if atherosclerosis of distal segments is very advanced. The periprocedural risk is high, especially if comorbidities are present. However, long-term results remain unclear. The ongoing Syntax trial will clarify whether angioplasty of LMCA with drug-eluting stents can be equivalent to CABG. We present a case of a patient with occluded right coronary artery, severe stenoses of the LMCA, left anterior descending artery and left circumflex artery, and poor left ventricular ejection fraction in whom PCI for stenosis of unprotected LMCA with standby cardiopulmonary support was performed.
