Abstract Background Chronic total occlusion revascularization remains a challenging problem because of its complexity. We present a case of a patient with chronic total occlusion who was successfully revascularized with the use of a new device called a real-time intravascular ultrasound double-lumen microcatheter. Case presentation A 58-year-old East Asians woman presented to our hospital with a complaint of recurrent chest pain of 5 months’ duration. Angiography revealed chronic total occlusion of the right coronary artery from the right coronary artery ostium to the ostia of the posterolateral and posterior descending branches. A guidewire was passed to the distal right coronary artery but went into the false lumens at the posterior descending and posterolateral ostia after use of the antegrade and retrograde approaches. Hence, we used the new device to pass through the subintimal right coronary artery space with reentry into the true lumen before the posterior descending and posterolateral ostia. A stent was successfully deployed at the posterior descending and posterolateral ostia, and the final result was excellent. Conclusions This device was useful for finding the entry point and for reentry into the true lumen of a chronic total occlusion. It may be a valuable tool for recanalization of complex chronic total occlusion lesions. |
