CORONARY COMPUTED TOMOGRAPHY ANGIOGRAPHY FOR THE DETECTION OF CHRONIC TOTAL OCCLUSION

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

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...

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...

Computed tomography coronary angiography.

Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...

Coronary Computed Tomography Angiography

Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...
