Background
The diagnostic work-up for atrial fibrillation (AF) catheter ablation is often complex and expensive. Improving the organization of this work-up may help to streamline patient journeys and to reduce administrative burden and costs. Additionally, reorganizing the existing work-up provides the opportunity to integrate (translational) research into routine clinical care, hereby contributing to improved patient selection and improved care for future patients.
Purpose
The aim of this project was to optimize a care pathway for patients considered for AF ablation, with the goals to improve the patient journey and simultaneously integrate research into the clinical process.
Methods
The Lean Six Sigma approach was used to map the pre-existing process, identify constraints in the process and formulate countermeasures. The impact of this pathway optimization was evaluated using four outcome measures: (1) efficient use of medical resources, defined as the percentage of patients receiving the pre-ablation work-up and eventually undergoing AF ablation, (2) number of hospital visits and consultations with a cardiologist, (3) pathway compliance, defined as the percentage of patients that completed the work-up with a maximum of 2 outpatient hospital visits, a maximum of 1 cardiologist consultation, laboratory results available, and a complete echocardiogram available, and (4) completeness of scientific data, defined as the availability of a predefined set of relevant variables (clinical indicators, medication, laboratory results and echocardiography derived data).
Results
Five root causes for constraints in the pre-existing work-up were identified and corresponding countermeasures were formulated (Figure 1). The impact of the countermeasures was studied for 33 patients before and 26 patients after pathway optimization. After optimization, efficient use of resources increased from 44% to 95% (p<0.01). The project resulted in fewer hospital visits per patient (3.2 ±1.2 versus 2.3 ±0.8, p=0.01) and fewer cardiologist consultations (1.8 ±0.7 versus 1.0 ±0.3, p<0.01). Pathway compliance increased significantly (3% versus 73%, p<0.01), an increase that was reflected in all separate components of overall pathway compliance (Figure 2, panel A). The percentage of available data for scientific research increased from 80% to 94% (p<0.01), resulting in a complete dataset in 73% of patients after, compared to only 15% of patients prior to the optimization project (p<0.01, Figure 2, panel B).
Conclusions
This optimization project resulted in a more efficient care pathway for patients considered for AF ablation. The structural integration of research into the care pathway may lay the foundations for further improvements of AF care in the future.

Background
In patients with persistent atrial fibrillation (AF) it is difficult to determine the association between patient self-reported symptoms and the underlying heart rhythm (symptom-rhythm correlation [SRC]). No standardized strategy to assess SRC in AF patients is available.
Purpose
We assessed for the first time SRC in persistent AF patients using a mobile health approach of simultaneous photoplethysmography (PPG)-based rhythm monitoring and active interrogation of patient-reported symptoms, which provides a novel approach to systematically assess SRC in persistent AF.
Methods
Consecutive persistent AF patients planned for electrical cardioversion (ECV) used a mobile app to record a 60-second PPG and report symptoms once daily and in case of symptoms for four weeks prior and three weeks after ECV. Within each patient, SRC was quantified by the SRC-index defined as the sum of symptomatic AF recordings and asymptomatic non-AF recordings divided by the sum of all recordings.
Results
Of 88 patients (33% female, age 68±9 years) included, 78% reported any symptoms during recordings. The overall SRC-index was 0.61 (0.44-0.79). The study population was divided into SRC-index tertiles: low (<0.47), medium (0.47-0.73) and high (≥0.73). Patients within the low (vs high) SRC-index tertile had more often heart failure and diabetes mellitus (both 24.1% vs 6.9%). Extrasystoles occurred in 19% of all symptomatic non-AF PPG recordings. Within each patient, PPG recordings with the highest (vs lowest) tertile of pulse rates conferred an increased risk for symptomatic AF recordings (odds ratio [OR] 1.26, 95% coincidence interval [CI] 1.04-1.52) and symptomatic non-AF recordings (OR 2.93, 95% CI 2.16-3.97). Pulse variability was not associated with reported symptoms.
Conclusion
In persistent AF patients, simultaneous mobile app-based symptom and rhythm monitoring revealed a relatively low overall SRC, suggesting that the majority of patients experienced symptoms irrespective of AF. Extrasystoles can explain a minority of symptomatic non-AF PPG recordings. Pulse rate, but not pulse variability, is the main determinant of reported symptoms during AF and non-AF PPG recordings. Further studies are required to test whether mobile app-based SRC assessment can be implemented in current workflows and integrated into a personalized symptom and rhythm control AF management approach.

Background. Nowadays frequently deployed invasive catheter ablation therapy in patients with symptomatic atrial fibrillation (AF) is unfortunately associated with distress such as preoperative anxiety. Improving preoperative patient information may lower anxiety towards AF ablation procedures.
Purpose. To evaluate whether a lifelike 360˚ virtual reality (VR) patient information video decreases anxiety levels and improves patient preparation towards AF ablation as compared to standard preoperative patient information.
Methods. Consecutive patients planned for AF ablation were recruited from the outpatient AF clinic and were randomized into two groups: the control group and the intervention group (VR group). The control group received standard preoperative information through oral counselling and information leaflets, the VR group received the standard information as well as a short dedicated 360˚ VR video (via in-hospital VR headset and disposable cardboard VR glasses for home use). Online questionnaires (aimed at information provision, anxiety and procedural experience) were administered both pre- and post-ablation.
Results. A total of 103 patients (39.8% female, age 64 [58-71] years) were included in the analysis. The VR group (n = 58) reported to be clearly better informed about catheterization laboratory environment (78% vs. 73%) and the course of the procedure (82% vs. 78%), indicated fewer concerns about the procedure (47% vs. 55%) and were eager to learn even more (82% vs. 74%) as compared to controls (n = 45). However, there was no significant difference in the anxiety scores between the VR group and controls (10 [8-12] vs. 10 [8-14], p = 0.548). Home use of the video was satisfactory and resulted in discussion with relatives. Patient overall satisfaction was higher in VR group as compared to controls (84% vs. 81%).
Conclusions. This study shows that a dedicated 360˚ VR video reduces concerns but does not reduce anxiety scores. Though, it easily improves procedural knowledge, patient information and patient satisfaction. Especially in times of remote patient care, this new way of informing patients may be of added value.
