Noninvasive Discrimination of Coronary Chronic Total Occlusion and Subtotal Occlusion by 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...

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

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...

Editorial Chronic Coronary Total Occlusion

Chronic total occlusion (CTO) is quite frequent finding in coronary artery disease. Comprised of a combination of fibrocalcific and thrombotic elements, CTO has been reported in approximately onethird of patients undergoing diagnostic coronary angiography. This thematic issue goes in depth into “coronary CTO ” that still represents the last frontier in percutaneous coronary intervention (PCI). ...

Noninvasive coronary angiography with multislice computed tomography.

CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study conducted in a referral center setting in Germ...
