Left Atrial Pressure-Guided Heart Failure Optimization During Atrial Fibrillation Ablation (LAP AF-HF)
Sponsor: Medical College of Wisconsin
Summary
This study examines whether measuring blood pressure inside the left upper chamber of the heart during a procedure to treat an irregular heartbeat called atrial fibrillation can help identify patients who would benefit from heart failure medications. During atrial fibrillation ablation, a catheter crosses into the left atrium, allowing direct measurement of left atrial pressure. When the pressure is elevated (15 mmHg or higher), it may indicate that the heart is under strain from unrecognized or undertreated heart failure. Patients with elevated left atrial pressure during ablation are referred for heart failure evaluation and medication optimization within 24 hours of the procedure. The study compares outcomes in these patients to a group of patients who had the same elevated pressures but received standard care without a structured heart failure evaluation. The study measures whether the heart failure treatment pathway leads to greater use of recommended heart failure medications, improvements in heart pumping function and heart chamber size, and reduction in irregular heartbeat episodes over the following year

Interventions
LAP-Triggered Heart Failure Optimization Pathway
Structured heart failure consultation within 24 hours of atrial fibrillation ablation triggered by intraprocedural mean left atrial pressure of 15 mmHg or greater. Consultation includes review of cardiac history, volume status assessment, echocardiographic review, and individualized guideline-directed medical therapy recommendations based on left ventricular ejection fraction phenotype. Final prescribing decisions rest with the treating clinical team
