Optical Coherence Tomography in Spontaneous Coronary Dissection and in the Complications Following Percutaneous Treatment
A 53-year-old man who had recently abandoned triple antihypertensive therapy was referred by his healthcare center following a first episode of angina at rest, which coincided with a significant increase in blood pressure (180/100 mmHg) and was accompanied by diffuse transitory ST-segment depression. Coronary angiography showed tapering of the proximal-middle segment of the median branch, which intracoronary nitroglyc-erin failed to modify ( Fig. 1A). As spontaneous coronary dissection (SCD) was suspected, optical coherence tomography (OCT) was used to study the vessel after unfractionated heparin (85 U/kg) was administered. The OCT confirmed focal intimal rupture (Fig. 1Aa) and revealed a ...
