Functional mitral regurgitation in patients with heart failure and reduced ejection fraction is associated with high morbidity and mortality, especially when other serious conditions are present. Here we present a 69-year-old patient with advanced heart failure with reduced ejection fraction (HFrEF), severe secondary mitral regurgitation, stage 5 chronic kidney disease on haemodialysis, complete atrioventricular (AV) block with a permanent pacemaker, and a history of haemorrhagic stroke. Due to the extremely high surgical risk, transcatheter edge-to-edge repair with MitraClip was performed, resulting in a reduction of mitral regurgitation from grade IV to grade I+ without signifi cant mitral stenosis. Five months later, follow-up showed the result was lasting and the device remained stable in place. This case shows that transcatheter edge-to-edge repair (TEER) can be an effective option for high-risk patients with multiple comorbidities.
