After being admitted, the patient underwent coronary angiography, which revealed a highly calcified subtotal occlusion in the middle right coronary artery (RCA) b, 30–40% stenosis in the proximal left anterior descending artery (LAD), 40% stenosis in the middle left circumflex artery (LCX) and 90% stenosis in the middle obtuse marginal artery (OM). One-year prior to her admission, the patient had undergone computed tomography angiography, which had revealed multi-vessel disease with severe calcification a. The first case was a 74-year-old female who was admitted to the hospital because of severe exertional chest pain. Here, we report four cases in which the stents failed to cross lesions using conventional percutaneous coronary intervention (PCI) techniques, but all target lesions were successfully stented using a new combined technique. However, there are still other lesions that cannot be crossed, even with the aforementioned techniques. With the application of parallel wire, anchor balloon, and “child-in-mother” catheter,, , some difficult lesions can be successfully stented. ,, However, interventional cardiologists still address difficult scenarios in everyday clinical practice, such as variant coronary artery origins and severely calcified and highly tortuous lesions. Over the last decade, a number of treatment strategies for complex coronary lesions have been utilized in varying clinical settings. Three authors contributed equally to this work Anchor balloons assisted deep intubation of 5F catheters for uncrossable lesions.

Keywords: Anchor balloon, child-in-mother catheter, percutaneous coronary intervention We report four cases in which the stents failed to cross lesions using the conventional percutaneous coronary intervention techniques, but all the target lesions were successfully stented finally using a new combined technique of anchor balloon assisted deep intubation of 5F “child-in-mother” catheter.
