Rev Esp Cardiol. 2009;62(5):576-88 587 of the distal circumflex artery, severe stenosis of the first marginal artery and slightly reduced left ventricular ejection fraction. A percutaneous coronary intervention was also performed during the procedure. After the deobstruction and first dilation with balloon of the distal circumflex, the patient began to feel chest pain and an angiograph showed a dissection image. After recovering good coronary flow, a study of the vessel with OCT was carried out using the technique described as proximal coaxial balloon occlusion and manual cleansing with saline serum of the lumen, automatic removal of the probe, at a speed of 1 mm/s. An intimal flap image was viewed in the dilated vessel (Figure 1). Subsequently, it was treated through the implantation of conventional stents in the distal circumflex artery and the second marginal artery, with an optimum angiographic result reevaluated through OCT (Figure 2). The acquisition of the images assumed a total delay of less than 10 minutes. This is the first documented case in which a high resolution image is obtained of a wide coronary dissection before treating it, prior documentation centred on the microdissections produced by the free edge of the stent after its implantation.4 Although the OCT did not influence the decision-making when dissecting, it did allow for an evaluation of the final result, as well as characterisation of the coronary dissection anatomy to perfection. It is therefore a very illustrative Coronary Artery Dissection Assessed by Optical Coherence Tomography

The Diagnosis of Spontaneous Coronary Artery Dissection by Optical Coherence Tomography
Spontaneous coronary artery dissection (SCAD) is rare, but it frequently presents as acute myocardial infarction. It is frequently fatal and most cases are diagnosed at autopsy. We herein present the case of a 65-year-old woman with ST-elevation and myocardial infarction due to SCAD. Optical coherence tomography (OCT) helped us to confirm the diagnosis. The information on the intravascular morp...

متن کاملCombined Assessment by Optical Coherence Tomography and Intravascular Ultrasound
The left internal thoracic artery (LITA) is considered the most reliable coronary artery bypass grafting conduit due to its high rate of long-term patency. LITA grafts are extremely durable and associated complications are infrequent. We present a case with spontaneous spiral dissection of a LITA graft to the left anterior descending artery, which was assessed by optical coherence tomography (O...

Optical Coherence tomography (OCT) is a light-based imaging modality which shows tremendous potential in the setting of coronary imaging. Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome (ACS). The diagnosis of SCAD is made mainly with invasive coronary angiography, although adjunctive imaging modalities such as computed tomography angiography, IVU...
