Initial experience with a virtual atrial fibrillation clinic after pulmonary vein isolation (2024)

Introduction

To detect recurrent atrial fibrillation (AF), a variety of methods are used, ranging from incidental electrocardiogram to rhythm monitoring with implantable loop recorders (ILRs). In clinical practice, routine use of ILRs is not feasible due to cost. Repeated (week)-Holters cause a considerable burden, both on patients and hospitals, and moreover are inadequate for detecting recurrent AF.

Purpose

To investigate whether remote monitoring (RM) is feasible in patients with AF after pulmonary vein isolation.

Methods

We set up a virtual AF clinic. Patients were equipped with a photopletysmography (PPG) application and asked to perform a recording when symptomatic. Recordings uploaded to the Hospital Electronic Patient Dossier and monitored by dedicated eNurses. The number of hospital contacts, hospital visits, electrocardiograms and Holter recordings were noted. Patient satisfaction and quality of life was measured by (validated) questionnaires. Comparisons were made with a historic control group from Jan-March 2019 with a traditional follow up of outpatient visits, electrocardiograms and Holters.

Results

157 patients were studied, 78 in the RM group and 79 in the control group. Mean age was 63 ± 10 years, 64% male. AF was paroxysmal in 68% of patients. Follow-up was 1 year and completed in all patients. In the RM group, patients performed 16±29 recordings/year. AF was detected in 37 (47%) patients on RM. While more planned remote contacts were performed in the RM group, significantly less planned and unplanned outpatient clinic visits, AF-related hospital admissions, and Holters took place. Patients report a high satisfaction with this form of remote monitoring.
