Massive Air Embolism During MitraClip Insertion
This case describes massive air embolism occurring a MitraClip procedure. This most likely occurred when the guide catheter was against the left atrial wall, resulting in external air entrainment. There was air embolism to the right coronary artery causing acute myocardial ischemia and ventricular fibrillation. The patient was successfully rescued and recovered. She underwent a successful MitraClip procedure subsequently.
