http://dx.doi.org/10.1016/j.ijcha.2014.10.005 2352-9067/© 2014 The Authors. Published by Elsevier Ireland Ltd. This is an open access articl ventricle (LV) with normal LV function. The patient was scheduled for a coronary angiogram that showed a patent left coronary artery and a complete occlusion of ostial right coronary artery (RCA). The RCA is opacified through collaterals from left coronary artery reaching the ostial stump. Collateral circulation is poor through septal connections but, notably, there is large albeit tortuous atrial collateral form left circumflex (LCX) connecting with the proximal RCA (Fig. 1, panels A and B). An attempt to recanalize RCA from an antegrade route failed due to the inability to cross the occlusion and place the wire in the true lumen. Subsequently, the patient was scheduled for a new attempt for recanalization of RCA via retrograde approach through the atrial collateral. The collateral could be wired with a Fielder XT coronary wire (Asahi Intecc Co., LTD) but

A Case of Intra- and Extra-Mural Hematomas During Recanalization for Chronic Total Occlusion
An intramural hematoma is an accumulation of blood between the internal and external elastic membranes within the medial space, whereas an extramural hematoma is a dilution and/or dissemination of blood throughout the adventitia. Intra- and extra-hematomas are observed by intravascular ultrasound during percutaneous coronary intervention (PCI). The patient described herein presented with angina...
متن کاملAortic root and extensive coronary dissections complicating recanalization of chronic right coronary artery occlusion: refraining from stenting may have a favorable outcome!
Aortic root dissection is a rare, potentially life-threatening complication of revascularization procedures. We report a case of recanalization of chronic total occlusion of the right coronary artery. A huge coronary dissection with a false lumen was created using commercially available guidewires during attempts to establish a connection with the distal true vessel lumen. In addition, an aorti...
متن کاملSuccessful percutaneous coronary intervention for an in-stent chronic total occlusion in a patient with dextrocardia: a case report
BACKGROUND Percutaneous coronary interventions of chronic total occlusion represent one of the most challenging issues in interventional cardiology. A Caucasian patient with dextrocardia presented with an in-stent chronic total occluded right coronary artery, a constellation which has not been described previously in the literature. CASE PRESENTATION A 69-year-old man with pre-known situs inv...
متن کاملChanges in Coronary Perfusion after Occlusion of Coronary Arteries in Kawasaki Disease
PURPOSE Myocardial infarction in children with total occlusion of a coronary artery after Kawasaki disease is rare due to multiple collateral vessels. We aimed to investigate the changes in coronary perfusion associated with coronary artery occlusion after Kawasaki disease. MATERIALS AND METHODS Eleven patients with coronary artery occlusion after Kawasaki disease were investigated. Serial co...
متن کاملBalloon Occlusion of the Contralateral Iliac Artery to Assist Recanalization of the Ipsilateral Iliac Artery in Total Aortoiliac Occlusion: A Technical Note
Endovascular recanalization of chronic total aortoiliac occlusion is technically challenging. Inability to reenter the true aortic lumen, following retrograde iliac recanalization, is one of the most common causes of failure. We describe a case of a total aortoiliac occlusion where balloon occlusion of the right common iliac artery, following its recanalization from a brachial approach, was use...
