Permanent Pacemaker Implantation or Cardioneuroablation in Sinus Node Dysfunction

Sinus Node Dysfunction

This is a noncommercial, physician-initiated, monitored, multicenter, prospective randomized clinical trial, a proof-of-concept study, investigating a treatment strategy only. The study will use medical products applied for invasive and nonivasive procedures performed at the participating centers.

Cardioneuroablation Versus Pacemaker Implantation for the Treatment of Symptomatic Sinus Node Dysfunction...

Sinus Node DysfunctionSick Sinus Syndrome

Endocardial ganglion plexus ablation (cardioneuroablation) represents a promising therapeutic technique for the treatment of vasovagal syncope (VV), functional atrioventricular block (AVB) and sinus node dysfunction (SND) with a component of vagal hypertonia. Nevertheless, there is currently a paucity of literature about the results according to the type of presentation (VV, AVB or SND). The investigators aim to assess the safety and efficacy of cardioneuroablation for the treatment of symptomatic SND.

Pulmonary Artery Pressure and Right Heart Evaluation for Patients Requiring Physiological Pacing...

Heart Failure With Reduced Ejection FractionAtrial Fibrillation3 more

With the aging of society, the use of cardiac pacing in patients with irreversible bradycardia is increasingly widespread. As early as the 1950s, right ventricular pacing (RVP) began to be used in patients with atrioventricular block or sick sinus syndrome, but in fact such pacing could cause ventricular asynchrony, which could lead to long-term myocardial perfusion injury, valvular regurgitation, heart failure, and increased risk of ventricular tachycardia and ventricular fibrillation. The latest guideline recommended reducing the proportion of right ventricular pacing. Additionally, in patients with heart failure with reduced ejection fraction (EF ≤ 35%) and complete left bundle branch block, cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) has been recommended to improve cardiac function, but only about 30% of patients benefit from it, which may be related to poor left ventricular pacing site and myocardial scarring. In theory, His bundle pacing (HBP) compared with RVP can reduce the risk of functional tricuspid regurgitation when the lead position lies on the atrial side of the tricuspid valve, which may improve the right heart function and pulmonary artery pressure. In 2021, Domenico Grieco et al. explored the effect of HBP on right heart function. After 6 months of follow-up, it was found that HBP improved right heart function and pulmonary artery pressure compared with RVP. At present, there are few discussions on the effect of physiological pacing on right ventricular hemodynamics, and the sample size is small. Internationally, the discussion of the assessment of hemodynamics is limited to non-invasive evaluation (such as echocardiography, ECG, SPECT) The gold standard for right heart hemodynamics evaluation is the measurement of invasive right heart catheterization, and there has been no relevant research so far, so the investigators further designed a study of the effect of physiological pacing on hemodynamics.

The Fluoroless-CSP Trial Using Electroanatomic Mapping

Sinus Node DysfunctionHeart Block AV3 more

The goal of this study is to assess the feasibility, accuracy and safety of performing fluoroless (or low fluoro) conduction system pacing utilizing electro-anatomic mapping (EAM) with the CARTO 3 mapping system (Biosense Webster Inc, Irvine, CA) in comparison to a group of patients undergoing conventional conduction system pacing (CSP) Implants.

Sinus Node DiseaseAtrioventricular; Block1 more

A multicenter, prospective, randomized study in a 1:1 ratio, single-blind with double-blind evaluation to evaluate the superiority of physiological ventricular pacing (proposed modality) vs. managed ventricular pacing (control) for prevention of persistent AF (PeAF) occurrence in patients with prolonged atrioventricular interval (PR≥180 ms) and indication for pacing: sinus node disease and/or paroxysmal type 1 or 2-second degree AV block.

Suture Closure AFtEr VEIN Access for Cardiac Procedures (SAFE-VEIN) Trial

Atrial FibrillationAtrial Flutter6 more

Primary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.

Clinical Benefits of the Closed Loop Stimulation in Sinus Node Disease

Sinus Node Disease

The study is designed as a multi-center, international, prospective, parallel, randomized, single blinded trial comparing the time to first primary endpoint event (Sustained Paroxysmal AF/Persistent AF or stroke/TIA) occurrence in a follow up period of 3 years, between Closed Loop Stimulation (CLS) ON versus OFF, on top of a DDD pacing in patients with pacemaker or ICD indication who require dual-chamber pacing due to sinus node disease (SND), with or without atrioventricular (AV) block.

Allometric-Pace Study

Sinus Node Dysfunction

The goal of this observational study is to improve quality of life in sinus node dysfunction patients by utilizing allometric lower rate pacing (or called personalized lower rate, PLR) in standard commercially available dual-chamber pacemakers. The primary objective is to achieve a significant improvement in patients' quality of life with use of PLR pacing in comparison with the control group with nominal lower rate in patients with implanted dual-chamber pacemaker. The secondary objectives are to assess cardiac functional changes in echocardiography of ventricular mechanical performance with a PLR pacing in comparison with the control group with nominal lower rate, and to assess the viability of using elevated blood pressure as a marker for undetected bradycardia and providing allometric rate to correct bradycardia-related increase in arterial systolic blood pressure.
