Catheter kinking during coronary angiography can be challenging. A novel Raptor grasping device successfully retrieved a kinked catheter in a patient with difficult anatomy when traditional methods failed.

Area of Science:

Interventional Cardiology
Vascular Surgery

Background:

Catheter kinking is a frequent complication during coronary angiography, especially in patients with tortuous vasculature.
Conventional retrieval techniques may prove ineffective in these complex cases.

Keywords:

catheter kinking coronary angiography mitral regurgitation papillary muscle rupture raptor grasping device tortuous aorta
