Percutaneous edge-to-edge mitral valve repair for mitral regurgitation improves heart failure symptoms in heart failure with preserved ejection fraction patients.

ABSTRACT:

Aims

Therapeutic options for patients with heart failure with preserved ejection fraction (HFpEF) are sparse. Mitral regurgitation (MR) is a common feature of HFpEF and worsens heart failure symptoms and prognosis. Our study examines the outcome of patients with preserved left ventricular ejection fraction (LVEF) and elevated left atrial (LAP) or left ventricular filling pressures (LVEDP), indicative of HFpEF, after undergoing percutaneous edge-to-edge mitral valve repair (pMVR) for moderate-severe MR.

Methods and results

Two hundred eleven patients with preserved LVEF (>50%), who underwent pMVR, were dichotomized by LAP (< / ≥15 mmHg) and LVEDP (< / ≥16 mmHg). Forty-nine per cent of patients showed elevated LAP, and LVEDP was elevated in 55%, both indicating HFpEF. Patients
