Abstract
We report the case of a 73-year-old male with a history of recurrent coronary interventions who presented with progressive angina and was diagnosed with a chronic total occlusion (CTO) of a heavily calcified and tortuous right coronary artery (RCA). Standard antegrade and retrograde techniques were attempted but failed due to the complexity of the lesion. A novel "Drag-Drill" technique was employed, utilizing a retrogradely externalized RG3 guidewire as a rotational atherectomy wire, enabling successful rotational atherectomy and percutaneous coronary intervention (PCI). The technique involved protecting the distal tip of the guidewire with a retrograde microcatheter to maintain stability and prevent vascular injury. At the 3-month follow-up, the patient remained angina-free. This case highlights the "Drag-Drill" strategy as an innovative and effective approach for the treatment of severely calcified and tortuous CTO lesions, underscoring the importance of tailored techniques in complex cases.
期刊介绍：
Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
