Pulmonary Vein Systolic Flow Reversal and Outcomes in Patients From the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation (COAPT) Trial
Background
The implications of pulmonary vein (PV) flow patterns in patients with heart failure (HF) and mitral regurgitation (MR) are uncertain. We examined PV flow patterns in the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation (COAPT) trial (NCT01626079), in which patients with HF and moderate-to-severe or severe functional MR were randomized to transcatheter edge-to-edge repair (TEER) with the MitraClip device plus guideline-directed medical therapy (GDMT) vs. GDMT alone. We sought to evaluate the prognostic utility of baseline PV systolic flow reversal (PVSFR) in HF patients with severe MR and to determine whether the presence of PVSFR can discriminate patients most likely to benefit from TEER in COAPT trial patients.
Methods
Patients were categorized by the echocardiographic core laboratory-assessed baseline presence of PVSFR. Two-year outcomes were examined according to PVSFR and treatment.
Results
Baseline PV flow patterns were evaluable in 526/614(85.7%) patients, 48.9% of whom had PVSFR. Patients with PVSFR had more severe MR, reduced stroke volume and cardiac output, greater right ventricular dysfunction, and worse hemodynamics. By multivariable analysis, PVSFR was not an independent predictor of 2-year all-cause death, or heart failure hospitalization (HFH). The reductions in the 2-year rates of all-cause death and HFH with TEER compared with GDMT alone were similar in patients with and without PVSFR (Pinteraction = 0.40 and 0.12, respectively). The effect of TEER on improving Kansas City Cardiomyopathy Questionnaire scores and 6-minute walk distance were also independent of PVSFR.
Conclusions
In the COAPT trial, PVSFR identified HF patients with severe MR and more advanced heart disease. Patients with and without PVSFR had consistent reductions in mortality, HFH, and improved quality-of-life and functional capacity after TEER.
