Systematic Ambulatory ECG Monitoring Following TAVI (RECORDII)

Systematic Ambulatory ECG Monitoring Following TAVI: A Prospective Randomized Trial.

This multicenter, prospective, randomized superiority trial will evaluate whether systematic 14-day ambulatory ECG monitoring following hospital discharge after transcatheter aortic valve implantation (TAVI) reduces the risk of sudden death, symptomatic arrhythmic events, or stroke within 1 year compared with standard post-discharge care. Patients undergoing successful TAVI without permanent pacemaker implantation and presenting with at least one ECG conduction abnormality at hospital discharge will be randomized to receive either ambulatory ECG monitoring or standard follow-up. All participants will undergo routine clinical follow-up at 30 days and 1 year after TAVI.

Detaljerad beskrivning

Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis. Despite advances in transcatheter heart valve technology and procedural techniques, conduction disturbances remain among the most frequent complications following TAVI. High-grade atrioventricular block, complete heart block, and new-onset bundle branch block may occur after the procedure and can lead to delayed permanent pacemaker implantation or life-threatening arrhythmic events. The increasing adoption of minimalist TAVI pathways with hospital discharge within 24-72 hours raises concerns that clinically significant arrhythmias may develop after discharge and remain undetected.

Ambulatory electrocardiographic (ECG) monitoring provides continuous rhythm surveillance during daily activities and enables the early detection of both symptomatic and asymptomatic bradyarrhythmias and tachyarrhythmias. Previous observational studies have demonstrated that clinically significant bradyarrhythmias occur in approximately 5-10% of patients during the first weeks after TAVI, particularly among those with baseline or new-onset conduction abnormalities. Ambulatory ECG monitoring has also identified previously unrecognized atrial fibrillation, allowing timely initiation of anticoagulation therapy in patients at high risk of thromboembolic events.

Although several prospective studies have evaluated ambulatory ECG monitoring after TAVI, most have been observational and were designed primarily to describe the incidence of post-procedural arrhythmias rather than to assess their impact on clinical outcomes. Preliminary evidence from the RECORD pilot study suggested that systematic ambulatory ECG monitoring after hospital discharge was associated with earlier identification and treatment of clinically significant arrhythmias and a reduction in the composite of sudden death, symptomatic arrhythmic events, and stroke during 1-year follow-up, with the greatest benefit observed among patients with conduction abnormalities at hospital discharge.

This randomized trial has been designed to provide definitive evidence regarding the clinical value of systematic ambulatory ECG monitoring after TAVI in patients at increased risk of post-procedural conduction disturbances. The study will evaluate whether early detection and management of clinically significant arrhythmias can improve clinical outcomes during the year following the procedure.

Intervention / Behandling
Experimentell: Ambulatory ECG monitoring
Participants will undergo ambulatory ECG monitoring at hospital discharge following TAVI. Continuous ECG monitoring will be performed for 14 days using an ambulatory ECG monitoring device. Clinically significant bradyarrhythmias or tachyarrhythmias detected during monitoring will be reviewed and managed according to clinical practice, including appropriate therapeutic interventions when indicated.
Participants randomized to the intervention arm will undergo systematic ambulatory ECG monitoring at hospital discharge following the TAVI procedure. A wearable ambulatory ECG monitoring device will be applied for continuous rhythm monitoring during a 14-day period. The device will allow detection of clinically significant bradyarrhythmias and tachyarrhythmias. Detected arrhythmic events will be reviewed by the study team, and appropriate clinical management, including further evaluation or therapeutic intervention, will be performed according to the nature of the detected abnormality and standard clinical practice.
Inget ingripande: Standard care (no ambulatory ECG monitoring device).
Participants will receive standard post-TAVI care without systematic ambulatory ECG monitoring at hospital discharge. Clinical follow-up will be performed according to routine practice.
