Does the antegrade dissection and re-entry (ADR) technique successfully manage an entrapped microcatheter tip during complex PCI?
Advanced interventional strategies like the ADR technique can successfully resolve complex coronary complications such as an entrapped microcatheter tip during PCI.
This case report describes the successful management of a complex percutaneous coronary intervention (PCI) in a 78-year-old man with a history of coronary artery bypass grafts. The patient presented with refractory angina symptoms and underwent PCI to the obtuse marginal (OM) vessel. The lesion proved to be balloon and microcatheter uncrossable and subsequent entrapment of a dislodged microcatheter tip, completely occluding vessel flow. Conventional retrieval methods failed, necessitating the use of the antegrade dissection and re-entry (ADR) technique with a Stingray balloon. This approach successfully recanalized the vessel, bypassing both the original lesion and the entrapped microcatheter tip. The case highlights the importance of advanced interventional strategies, typically associated with chronic total occlusion (CTO) interventions, in resolving complex coronary complications. It emphasizes the need for interventional cardiologists to be proficient in diverse techniques to address rare but potentially serious complications during PCI.
Abdeldayem et al. (Thu,) conducted a case report in Refractory angina and complex percutaneous coronary intervention complication (n=1). Antegrade dissection and re-entry (ADR) technique with a Stingray balloon was evaluated on Successful recanalization of the vessel. The antegrade dissection and re-entry technique using a Stingray balloon successfully recanalized the vessel and bypassed an entrapped microcatheter tip during a complex PCI.
