Introduction: Cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes.
Case presentation: We describe a case where the tumor originated on the mitral valve and extended through the left ventricular outflow tract and aortic valve and into the left main artery obstructing it. Due to the hemodynamic instability of the patient, we proceeded for cardiac catheterization with the intention to aspirate the mass but were forced to do percutaneous intervention to stabilize the patient and bridge him to surgery.
Conclusions: The patient underwent surgery several days later with complete resection of the tumor and coronary stent retrieval but his left ventricular ejection fraction remained poor after several months and he was referred for cardiac transplantation.
