We report a patient that was successfully treated using a novel minimally invasive approach via the apex of the left ventricle. Case Report A 72-year-old man with hypertension, hyperlipidaemia, diabetes and renal impairment presented with recurrent heart failure from a severely leaking mitral bioprosthesis.
