Reverse Controlled Antegrade and Retrograde Subintimal Tracking in Chronic Total Occlusion of Right Coronary Artery
نویسندگان
چکیده
Passage failure of guidewire is still remained most common reason for percutaneous coronary intervention (PCI) failure in chronic total occlusion (CTO). Intravascular ultrasound study (IVUS) and cardiac CT angiography can help identify features that most influence current success rates of PCI. We report our experience using the reverse controlled antegrade and retrograde subintimal tracking technique under the aid of IVUS, cardiac CT angiography for an ambiguous CTO of proximal right coronary artery.

Subintimal dissection/reentry strategies in coronary chronic total occlusion interventions.
Subintimal dissection/reentry techniques are increasingly being used for crossing coronary chronic total occlusions both antegradely (using a knucle wire or the Bridgepoint system) or retrogradely (using the controlled antegrade and retrograde tracking and dissection, and reverse controlled antegrade and retrograde tracking and dissection technique). Subintimal dissection/reentry techniques can...
متن کاملRetrograde approach to successfully treat antegrade failure due to subintimal hematoma of a right coronary artery chronic total occlusion
2015 Use of antegrade dissection re-entry techniques for crossing coronary chronic total occlusions may occasionally fail due to subintimal hematoma formation. We describe use of the retrograde approach to successfully complete a right coronary artery chronic total occlusion intervention, in which re-entry was not possible after subintimal guidewire crossing due to extensive subintimal hematoma...
متن کاملA Novel, Modified Reverse Controlled Antegrade and Retrograde Subintimal Tracking Technique for Bypassing the Calcified Proximal Cap of Coronary Total Occlusions
Antegrade crossing is the most common approach to chronic total occlusions (CTOs). However, it is sometimes difficult to penetrate the proximal hard cap with guidewires, especially in the case of CTOs of anomalous coronary arteries because of a lack of support. Herein, we describe a novel, modified reverse controlled antegrade and retrograde subintimal tracking (CART) technique in which the dis...
متن کاملA complex dissected chronic occlusion: targeted balloon dilatation of false lumen to access true lumen, combined localized subintimal tracking and re-entry, parallel wire, contralateral injection and a useful antegrade lumen re-entry technique
Chronic total occlusion (CTO) angioplasty is one of the most challenging procedures remaining for the interventional operator. Recanalizing CTOs can improve exercise capacity, symptoms, left ventricular function and possibly reduce mortality. Multiple strategies such as escalating wire, parallel wire, see-saw, contralateral injection, subintimal tracking and re-entry (STAR), retrograde wire tec...
متن کاملSuccessful endovascular treatment of chronic total occlusion of superficial femoral artery using retrograde approach from deep femoral artery.
An 82 years-old man with intermittent claudication was admitted to our hospital. Computed tomography angiography showed his right superficial femoral artery (SFA) was chronic total occlusion (CTO), and we performed endovascular treatment (EVT). We advanced a guide-wire by contralateral transfemoral approach, but guide-wires could not penetrate the occluded SFA lesion antegradely. Thus, we tried...
