Crossing a Complex CTO Using BTG Crossing Devices

Haidar Yassin, MD

Dr. Yassin is board-certified in internal medicine, cardiovascular medicine and interventional cardiology. His practice covers the full spectrum of invasive and noninvasive cardiology with special interest in structural heart disease from aortic and pulmonary valve replacement, mitral valve repair, congenital defect repair (ASD/PFO) and septal ablation for hypertrophic cardiomyopathy. He also practices high-risk coronary intervention with hemodynamic LV support devices and also performs coronary and peripheral interventions as well as percutaneous management of deep vein thrombosis (DVT) and acute pulmonary embolism (acute PE). He attended medical school at the University of Baghdad-Iraq, completed his residency and cardiology fellowship at the State University of New York Downstate Medical Center and an interventional cardiology fellowship at Winthrop University in New York.

Dr. Yassin is an Associate Cardiologist at the Arizona Cardiology Group and is Director of Cardiac Imaging and Noninvasive Cardiology at the Banner Estrella Medical Center in Phoenix, Arizona and is an investigator in a multitude of clinical trials in the structural heart field.


This case highlights the use of the BTG CenterCross™ and BTG MicroCross™ to cross a complex mid-LAD CTO. The patient has a complex history of CAD in the target artery, visible by the proximal LAD stenting. After crossing the CTO utilizing the BTG CenterCross™, Dr. Yassin uses intravascular ultrasound to properly size the vessel for angioplasty and expansion of existing under-deployed stents.
