Abstract
Left ventricular assist devices (LVADs) are increasingly used in patients with end-stage heart failure (HF). There is a significant risk of HF admissions and hemocompatibility-related adverse events that can be minimized by optimizing the LVAD support. Invasive hemodynamic assessment, which is currently underutilized, allows personalization of care for patients with LVAD, and may decrease the need for recurrent hospitalizations. It also aids in triaging patients with persistent low-flow alarms, evaluating reversal of pulmonary vasculature remodeling, and assessing right ventricular function. In addition, it can assist in determining the precipitant for residual HF symptoms and physical limitation during exercise and is the cornerstone of the assessment of myocardial recovery. This review provides a comprehensive approach to the use of invasive hemodynamic assessments in patients supported with LVADs.

Prevalence of Heart Failure With Preserved Ejection Fraction in Patients Undergoing Atrial Fibrillation Ablation Based on Resting and Post-Tachycardia Pacing Left Atrial Pressure.

Abstract
Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are frequent co-morbid conditions. In patients with symptomatic AF and preserved left ventricular ejection fraction the clinical diagnosis of HFpEF may be difficult, as history, examination, and echocardiography are not sensitive or specific. This study sought to assess the prevalence of HFpEF in patients undergoing AF ablation utilizing resting and post-tachycardia pacing left atrial pressure (LAP) measurements. This retrospective cohort study consisted of consecutive patients with symptomatic AF and preserved left ventricular ejection fraction who had invasive hemodynamic assessment (IHA) of LAP under resting and post-tachycardia pacing conditions while undergoing AF ablation from 2020 to 2022 at a tertiary care academic medical center. Elevated LAP was defined as ≥15 mm Hg at rest and ≥15 mm Hg post-tachycardia pacing. Patients were stratified into 3 groups: (1) normal resting and post-tachycardia pacing LAP (control group), (2) elevated resting LAP (apparent HFpEF), (3) normal resting but elevated post-tachycardia pacing LAP (occult HFpEF). A total of 78 patients were included with age 64.6 ± 9.1 years, 28 (36%) female, body mass index 33.3 ± 6.5 kg/m2, 5 (6%) paroxysmal and 73 (94%) persistent AF, and CHA2DS2-VASc 3.0 ± 1.5. IHA categorized 31 (40%), 32 (41%), and 15 patients (19%) into groups 1, 2, and 3 respectively. Notably, while only 9 patients (12%) were diagnosed with HFpEF based on clinical evaluation, 47 patients (60%) were diagnosed by IHA. IHA in patients undergoing AF ablation suggests a high prevalence of clinically undiagnosed HFpEF through a novel methodology measuring resting and post-tachycardia pacing LAP.
