Insights
Complex coronary lesions pose challenges for percutaneous coronary intervention. A novel anchor balloon technique with a "child-in-mother" catheter successfully treated four cases where conventional methods failed, enabling stent delivery.
Area of Science:
- Interventional Cardiology
- Vascular Medicine
- Medical Device Technology
Background:
- Complex coronary lesions, including variant origins, calcification, and tortuosity, present significant challenges in percutaneous coronary intervention (PCI).
- Conventional PCI techniques sometimes fail to cross these difficult lesions, leading to suboptimal outcomes.
- The development of new devices and techniques is crucial for improving PCI success rates in complex cases.
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.
