Artery Disease

Patients presenting with chronic and acute chest pain constitute a common and important diagnostic challenge. This has increased interest in using computerized tomography for non-invasive visualization of coronary artery disease in patients presenting with acute chest pain to the emergency department, particularly the subset of patients who are suspected of having an acute coronary syndrome, but without typical electrocardiographic changes and with normal troponin levels at presentation. As a result of rapid developments in coronary computerized tomography angiography technology, high diagnostic accuracies for excluding coronary artery disease can be obtained. It has been shown that these patients can be discharged safely. The accuracy for detecting a significant coronary artery stenosis is also high, but the presence of coronary artery atherosclerosis or stenosis does not imply necessarily that the cause of the chest pain is related to coronary artery disease. Moreover, non-invasive detection of coronary artery disease by computerized tomography has been shown to be related with an increased use of subsequent invasive coronary angiography and revascularization, and further studies are needed to define which patients benefit from invasive evaluation following coronary computerized tomography angiography. Conversely, implementation of coronary computerized tomography angiography can significantly reduce the length of hospital stay, with a significant cost reduction. Additionally, computerized tomography is an excellent modality in patients whose symptoms suggest other causes of acute chest pain such as aortic aneurysm, aortic dissection, or pulmonary embolism. Furthermore, acquisition of the coronary arteries, thoracic aorta, and pulmonary arteries in a single computerized tomography examination is feasible, allowing ‘triple rule-out’ (exclusion of aortic dissection, pulmonary embolism, and coronary artery disease). Finally, other applications, such as evaluation of coronary artery plaque composition, myocardial function and perfusion, and non-invasive assessment of fractional flow reserve from coronary computerized tomography angiography, are currently being developed and may also become valuable in the setting of chronic and acute chest pain in the future.

Objectives Optical coherence tomography chronic total occlusion catheter, the Ocelot (Avinger Inc., Redwood City, CA), has been utilized to cross Trans-Atlantic Inter-Society Consensus D lesions. This study evaluated the preoperative computerized tomography angiography of chronic total occlusions in the superficial femoral artery to predict clinical success. Methods We reviewed all patients who underwent lower extremity procedures with the Ocelot catheter from June 2014 to August 2016. Patients who had a preoperative computerized tomography angiography were evaluated. Final outcomes, plaque morphology, lesion length, calcium surface area, lesion location, and patient characteristics were analyzed. Results A total of 107 patients underwent lower extremity interventions with the Ocelot catheter. Seventy patients had a preoperative computerized tomography angiography scan prior to lower extremity intervention and 77% (54) had Trans-Atlantic Inter-Society Consensus D lesions that were crossed. Mean age was 62.8 years and 68.6% were male. Mean chronic total occlusion length was 182.7 mm (170.8 mm crossed vs. 222.6 mm uncrossed, p = 0.03). Calcium distribution differed significantly ( p<.01): circumferential (14.8 vs. 12.5%); eccentric (85 vs. 62.5%); and complete calcium occlusion (0 vs. 25%) for lesions that were crossed and uncrossed, respectively. Significant differences ( p<.0001) were found when calcium occlusion was less than 50% (87 vs. 31%), 51–75% (9.3 vs. 31.2%), and 76–100% (3.7 vs. 37.5%). Total calcium length in crossed lesion was 51.6 mm, and 92.8 mm in uncrossed lesions ( p = 0.10). No significant differences were noted for patient gender, occlusion location (proximal, middle, and distal superficial femoral artery), and kidney function. Conclusion The Ocelot catheter is an effective method to cross long Trans-Atlantic Inter-Society Consensus D lesions. Superficial femoral artery lesions longer than 17 cm and focal plaque morphology, specifically a total cross-sectional area of calcium and a calcium surface area greater than 50% were most predictive of failure to cross Trans-Atlantic Inter-Society Consensus D superficial femoral artery lesions. Computerized tomography angiography is an effective tool to predict success for crossing chronic total occlusions using optical coherence tomography technology and a critical consideration for patient selection.
