Impact of Catheter Ablation on Jugular Venous Pulse Descent Pattern in Atrial Fibrillation: Insights into Heart Failure Prognosis
Le résumé fourni par la source
Background: A dominant Y descent in the jugular venous pulse (JVP) is a marker of less right ventricular (RV) distensibility and poor prognosis in heart failure (HF), and is frequently observed in atrial fibrillation (AF). Whether catheter ablation (CA) can reverse this abnormal waveform remains unknown. Methods: We conducted a single-center observational study of 166 patients who had undergone CA for AF. JVP waveforms were assessed at baseline, within 48 h after CA, and during follow-up. Results: Among 65 patients in AF at baseline, 64 (98 %) exhibited a dominant Y descent in JVP. Following CA, 47 (73 %) normalized immediately, with additional patients improving during follow-up. Persistence of dominant Y descent in JVP was associated with longer AF duration and previous open-heart surgery. In 101 patients in sinus rhythm at baseline, no significant waveform changes were observed. Conclusions: AF-related impairment of RV distensibility is largely reversible with CA. This reversal may represent an important physiological mechanism underlying CA-related improvement in HF outcomes. Further studies are warranted to determine the prognostic value of JVP normalization.
