Right atrial thrombus removal with use of the ŌNŌ retrieval device

Catheter Cardiovasc Interv. 2023 Nov;102(6):1105-1108. doi: 10.1002/ccd.30877. Epub 2023 Oct 19.


Intracardiac masses and specifically right atrial thrombi can be difficult to manage and carry a high mortality rate. Typically, surgical removal or mechanical thrombectomy can be performed though may not be suitable for all patients. We present a unique case of a sickle cell patient with a large pedunculated right atrial thrombus that was successfully extracted using the novel ŌNŌ Retrieval Device.
