Abstract :
Percutaneous coronary intervention (PCI) involving the anomalous coronary artery is challenging with respect to difficulty in
achieving stable catheterization. Rotational atherectomy (RA) can facilitate severely calcified lesions to improve stent delivery and
stent expansion; however, its utility in tortuous and angulated coronary arteries is limited with difficulty in delivery of the RA burr.
-e mother-and-child technique is effective for complex PCIs with increased backup force for device delivery in such complicated
cases. We report a case of successful rotational atherectomy using the “mother-and-child” technique with a Dio thrombus
aspiration catheter for an angulated calcified lesion in an anomalous origin of the right coronary artery
