It was reported that a shaft break occurred.The 90% stenosed target lesion was located in a non-tortuous and severely calcified coronary artery.A 2.50mm x 15mm emerge balloon catheter was advanced in an attempt to trap a wire with the balloon.However, when the balloon was inflated and the microcatheter pulled back, the balloon shaft broke and became lodged in the circumflex artery.A failed attempt was made to snare the detached piece for removal, leading to the need for a sternotomy surgical intervention.The patient was admitted to the hospital beyond standard of care.No further information was provided.
