False lumen stenting: uncommon stent occlusion demonstrated by intravascular ultrasound

A 53-year-old man with hypertension and hyperlipidaemia was referred to our hospital for a third attempt to recanalise an occlusive in-stent restenosis (ISR) in the circumflex artery (LCX). In 2003, the patient had inferolateral myocardial infarction with a triple-vessel disease. Coronary bypass grafting was performed. In March 2006, stress scintigraphy for screening showed lateral ischaemia. Coronary angiography revealed an occlusion of the right internal mammary artery to a posterolateral branch. In another centre, coronary intervention was performed for subtotal occlusion in the LCX (Figure 1A). During the procedure a guidewire entered a false lumen (Figure 1B) and finally two bare metal stents ...
