Optical coherence tomography assessment of the spatial distribution of culprit ruptured plaques and thin-cap fibroatheromas in acute coronary syndrome
Aims: Plaque rupture and subsequent thrombosis is known to be the most important pathology leading to acute coronary syndrome (ACS). We investigated by optical coherence tomography (OCT) whether in ACS there is an association of the location of the culprit plaque in the coronary tree with plaque rupture and/or thin cap fibroatheroma (TCFA). Methods and results: We included 74 patients presenting with ACS that underwent OCT study of the culprit lesion. The distance of the culprit lesion from the ostium was measured angiographically, and the presence of rupture and/or TCFA was assessed by OCT. Sixty-seven patients were analysed ...
