Introduction: A rare complication of mitral valve surgery is the injury of the circumflex artery due to their close anatomical proximity resulting in a perioperative myocardial infarction and subsequent fibrosis with increased risk of developing ventricular arrhythmias. Case presentation: We hereby describe the case of a 74-year-old male patient who underwent minimally invasive mitral valve replacement surgery for severe mitral regurgitation two weeks prior to presenting to the emergency department with dyspnea, palpitations and slight thoracic discomfort. He was diagnosed with recurrent sustained monomorphic ventricular tachycardia due to inferior wall myocardial infarction. Angioplasty of the culprit lesion was attempted, but the procedure failed due to the elastic recoil of the vessel. Our patient received antiarrhythmic therapy and an implantable cardioverter-defibrillator for secondary prevention of sudden cardiac death, with no further recorded episodes of ventricular tachycardia. Conclusion: Although injury of the circumflex coronary artery during mitral valve surgery is described as rare, we strongly believe that increasing awareness of the potential risks involved can further prevent fatal complications.
