Simultaneous kissing stents for the treatment of left main stenosis in cardiogenic shock

ABSTRACT

Significant narrowing of the left main coronary artery puts the patient at high risk, since occlusion of this vessel, if unprotected by collateral flow or a patent bypass graft to either the left anterior descending or circumflex artery, compromises flow to approximately 75% of the left ventricle. Percutaneous coronary intervention of left main coronary artery may be the only life saving procedure. There are limited data on the general use of percutaneous intervention [PCI] in patients with acute myocardial infarction [MI] due to left main disease. Small series have noted in-hospital mortality rates of 30 to 35 percent following PCI with or without stenting. Moreover, cardiogenic shock secondary to acute MI, in patients with left main coronary artery disease, carries a very high mortality. Treatment options are limited especially when emergent coronary artery bypass surgery is not an option. We report a case of emergency angioplasty of left main coronary artery with simultaneous kissing stent technique in cardiogenic shock
