LAP-Triggered Pathway
Patients undergoing atrial fibrillation ablation with intraprocedural mean left atrial pressure of 15 mmHg or greater enrolled prospectively (2024-onwards).
Referred for heart failure consultation within 24 hours of ablation with structured guideline-directed medical therapy optimization targeting phenotype-appropriate therapy.
|
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
|
|
Standard of Care Controls
Historical cohort (2022-2023) of consecutive patients who underwent atrial fibrillation ablation with intraprocedural mean left atrial pressure of 15 mmHg or greater.
Received standard post-ablation care without protocolized heart failure consultation or left atrial pressure-triggered medication optimization.

Tidsramme |
|---|---|---|
|
Guideline Adherence Index
Tidsramme: Up to 36 months.
|
Number of heart failure medication classes prescribed divided by the number of classes for which the patient has a guideline-supported indication and no documented contraindication.
Ranges from 0 to 1 with higher values indicating greater adherence.
|
Up to 36 months.
|
|
Guideline Adherence Index Area Under the Curve
Tidsramme: Up to 36 months.
|
Time-weighted cumulative guideline adherence calculated from serial medication assessments at baseline, discharge, and scheduled follow-up intervals.
Higher values indicate greater sustained guideline-directed medical therapy implementation over time.
|
Up to 36 months.
|
|
Change in Left Ventricular Ejection Fraction From Baseline
Tidsramme: Up to 36 months.
|
Left ventricular ejection fraction measured by biplane Simpson method on transthoracic echocardiography per American Society of Echocardiography recommendations.
Reported as absolute change in percentage points from baseline.
|
Up to 36 months.
|
|
Change in Left Atrial Volume Index From Baseline
Tidsramme: Up to 36 months.
|
Left atrial volume indexed to body surface area measured by biplane area-length method on transthoracic echocardiography per American Society of Echocardiography recommendations.
Reported as absolute change in mL/m2 from baseline.
|
Up to 36 months.
|
|
Right Ventricular Function and Right Ventricular-Pulmonary Artery Coupling.
Tidsramme: Up to 36 months.
|
Composite right ventricular assessment including tricuspid annular plane systolic excursion in centimeters, tricuspid annular systolic velocity in centimeters per second, tricuspid regurgitation peak velocity in meters per second, and the ratio of tricuspid annular plane systolic excursion to tricuspid regurgitation peak pressure gradient.
Each parameter reported as change from baseline.
|
Up to 36 months.
|
|
Atrial Fibrillation Recurrence and Burden After Blanking Period
Tidsramme: Up to 12 month.
|
Atrial fibrillation recurrence defined as any episode of atrial fibrillation, atrial flutter, or atrial tachycardia lasting more than 30 seconds documented beyond a 90-day blanking period.
Atrial fibrillation burden defined as percentage of time spent in atrial fibrillation ascertained from cardiac implantable electronic device, implantable loop recorder, or ambulatory monitoring.
Both reported as post-blanking outcomes.
|
Up to 12 month.
