Application-Based Integrated Care in Patients After Pulse Field Ablation

Summary

"Atrial fibrillation (AF) is known as the most common sustained arrhythmia observed in clinical situation. Pulse Field Ablation (PFA) is a recently introduced, effective atrial fibrillation (AF) ablation modality. PFA is safe for treating patients with AF. The "MANIFEST-17K" international study showed important safety outcomes in 17,642 AF patients undergoing post-approval PFA, including no significant risk of esophageal damage, with PFA. PFA provides an appealing alternative to cryoablation and radiofrequency ablation, which often cause damage to non-targeted tissues, particularly the esophagus and phrenic nerve. An integrated care approach including risk factor management might be of benefit to the clinical outcomes of patients with AF. A mobile application-based integrated care approach is also relatively new and can reduce the burden of physicians and nurses. Recent studies showed that an integrated care approach to holistic AF care can improve the outcome of population-based studies. However, the effect of the mobile application-based integrated care approach has not been evaluated in ablation patients. Dementia, a decline in memory and other cognitive functions leading to disability in daily function is a common and feared geriatric condition. Although catheter ablation is one of the main treatments for AF, whether it can improve cognitive function in patients with AF remains unclear. Multiple observational trials have shown that catheter ablation is also associated with a lower risk of cognitive decline, dementia, and improved cognitive testing that can be explained through a variety of pathways. FARAPULSE™ PFA is becoming a widely used ablation technique in AF patients, and knowing the effect of an application-based integrated care approach after AF PFA ablation, and the change in cognitive function is novel. The hypothesis of the study is that AF freedom will be improved by using an application-based integrated care approach in AF patients after the FARAPULSE™ PFA. Another hypothesis is that because of the short procedure time of PFA, the cognitive function will be improved after PFA, and further improved using an application-based integrated care approach.

Eligibility

Inclusion Criteria:

1. patients who were treated with the FARAPULSE™ PFA for AF as a de novo procedure
2. Subjects who are willing and capable of providing informed consent
3. Subjects who are willing and capable of participating in App-base integrated care Subjects whose age is 18 years or above, or who are of legal age to give informed consent specific to state and national law

Exclusion Criteria:

1. Subjects with a current interatrial baffle or patch
2. Subjects with a known or suspected atrial myxoma
3. Subjects with myocardial infarction within 14 days prior to enrollment
4. Subjects with a recent (within 30 days prior to enrollment) Cerebral Vascular Accident (CVA)
5. Subjects who do not tolerate anticoagulation therapy
6. Subjects with an active systemic infection \*
7. Subjects with a presence of atrial known thrombus \*
8. Subjects with a known inability to obtain vascular access
9. Subjects who are pregnant or planning to be pregnant
10. Subjects with atrial fibrillation that is secondary to electrolyte imbalance, thyroid disease, alcohol, or other reversible / non-cardiac causes
11. Subjects with any prosthetic heart valve, ring, or repair including balloon aortic valvuloplasty
12. Subjects with a contraindication to an invasive electrophysiology procedure where insertion or manipulation of a catheter in the cardiac chambers is deemed unsafe per physician's medical judgment, such as, but not limited to, a recent previous cardiac surgery (e.g., ventriculotomy or atriotomy, CABG, PTCA/PCI/coronary stent procedure/unstable angina) and/or in patients with congenital heart disease where the underlying abnormality increases the risk of the ablation (e.g., severe rotational anomalies of the heart or great vessels)
13. Subjects with a life expectancy of ≤ 1 year per investigator's opinion
14. Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments. Each instance must be brought to the attention of the sponsor to determine eligibility.
