What this trial studies

POL-CA is a multicenter observational registry combining retrospective and prospective data on adults who have undergone or will undergo procedures that modify cardiac autonomic innervation, such as cardioneuroablation, sinoatrial-node-sparing hybrid ablation, and cardiac sympathetic denervation. The registry aims to enroll at least 1,000 participants across three age groups and to standardize data collection with a common POL-CA questionnaire and methodology. Data collected include clinical history, procedural details, perioperative and long-term complications, and patient-reported outcomes using EQ-5D, SF-36, VASIS, and MALMO scales. The goal is to provide a multicenter summary of patient characteristics, treatment patterns, and real-world outcomes for a spectrum of autonomic cardiac disorders.

Who should consider this trial

Good fit: Adults (≥18 years) with diagnoses such as vasovagal syncope, POTS, inappropriate sinus tachycardia, cardioinhibitory carotid sinus syndrome, symptomatic sinus bradycardia or functional AV block, or orthostatic hypotension who have undergone or are planned for cardioneuroablation, SN-sparing ablation, cardiac sympathetic denervation, or similar neuromodulation procedures are eligible.

Not a fit: Patients with structural heart disease requiring surgical intervention, those with a preexisting permanent pacemaker or ICD, individuals unable to complete follow-up or questionnaires, and those with severe psychiatric comorbidities are unlikely to benefit from participation in this registry.

Why it matters

Potential benefit: If successful, the registry could help doctors identify which patients benefit most from nerve-targeting heart procedures and improve treatment decisions and follow-up care.

How similar studies have performed: Smaller observational series and case reports have shown promising symptom improvements after cardioneuroablation and neuromodulation, but randomized controlled evidence is still limited.
