Differentiation of Acute Total Occlusion of Coronary Artery from Chronic Total Occlusion in Coronary Computed Tomography Angiography

Pitfalls of Noninvasive Discrimination Between Coronary Chronic Total Occlusion and Subtotal Occlusion by Coronary Computed Tomography Angiography.

We read with interest the paper by Choi et al. (1) regarding noninvasive discrimination of coronary chronic total occlusion (CTO) and subtotal occlusion (STO) by coronary computed tomography angiography (CTA). We recognize the potential clinical relevance of the noninvasive differentiation between these 2 entities because CTO usually involves a worse prognosis and more technical challenges in r...

Chronic total left main coronary artery occlusion.

A 65 year old man, smoker, presented with a history of exertional shortness of breath over the last 4 months. He denied any chest discomfort. On examination jugular venous distension was noted with bilateral basal crackles. He got symptomatic relief after treatment with diuretics and nitrates. His echocardiogramme revealed global hypokinesia of left ventricle with severe mitral regurgitation. H...

Coronary Computed Tomography Angiography Predicts Guidewire Crossing and Success of Percutaneous Intervention for Chronic Total Occlusion

Digital subtraction angiography in angioplasty of total coronary artery occlusion.

This report describes a digital subtraction angiographic technique used to simultaneously display the proximal and distal segments of three totally occluded coronary arteries in two patients undergoing percutaneous transluminal coronary angioplasty (PTCA). The advantage of this technique over routine cineangiography for PTCA of total occlusions is illustrated.

Usefulness of Intraprocedural Coronary Computed Tomographic Angiography During Intervention for Chronic Total Coronary Occlusion.

Although intraprocedural coronary computed tomographic angiography (CCTA) allows for scanning during intervention without relocation of the patient, studies have yet to report on its use during chronic total occlusion (CTO) intervention. Therefore, we investigated the role of CCTA during CTO intervention, particularly whether CCTA could be used to evaluate the location of guidewires. A total of...
