Abstract
A 56-year-old patient with no relevant medical history was admitted to our hospital due to ST elevation myocardial infarction. Echocardiography showed severe left ventricular dysfunction due to extensive anterior hypokinesia. Coronary angiography revealed acute proximal occlusion of the anterior descending artery with total chronic occlusion of the right coronary artery and the circumflex artery. Due to haemodynamic instability, it was decided to implant a stent in the anterior descending artery under Impella CP support. As the patient’s condition worsened, additional support was required. It was decided to perform a transaxillary Impella 5.5 implantation. A 10 mm Dacron graft was anastomosed to the right axillary artery and extracted by counterincision through the adjacent skin. Using a 23Fr introducer, a curved Teflon-coated guidewire was progressed through the aortic valve to the left ventricle. The curved guidewire was then replaced with a rigid 0.018 guidewire that was used to advance the Impella 5.5 under fluoroscopy and echocardiography guidance. Once the correct position was assessed, the therapy was started. As days went by under Impella 5.5 support, inotropes were gradually tapered off and the ventricular assist device could be explanted a week later. Significant improvement of the left ventricular ejection fraction was observed before discharge from the hospital.
