Anchor balloons assisted deep intubation of 5F catheters for uncrossable lesions

Abstract

A number of treatment strategies for complex coronary lesions have been utilized in varying clinical settings over the last decade. However, cardiologists still encounter some difficult scenarios such as variant coronary artery origins, severely calcified and highly tortuous lesions. 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.
