When the Right Coronary Artery is Tortuous and Too Big for Standard Coronary Stents: “The Child-in Mother Carotid Stent Technique”

Routine implementation of guide extension catheters in percutaneous coronary intervention (PCI) has significantly increased success rates in challenging anatomies, such as in tortuous and severe calcified vessels. Recently, the “Child-In-Mother technique” has been tested successfully in carotid artery stenting (CAS) in patients with severe tortuosity of the common or internal carotid artery (ICA). In the present report, we propose to use the “Child-in-Mother technique” to facilitate the delivery of a carotid stent in an ectatic, thrombotic and tortuous right coronary artery (RCA) in a patient presenting with acute coronary syndrome (ACS).
