Robotic-enhanced hybrid ablation for inappropriate sinus tachycardia: a world-first approach.

We describe a world-first robotic ablation for inappropriate sinus tachycardia. A 26-year-old woman with refractory inappropriate sinus tachycardia underwent robotic-enhanced hybrid ablation, combining electrophysiological mapping with superior visualization and access compared to video-assisted thoracoscopic surgery (VATS) approaches. Ablations normalized the heart rate from 120 to 70 bpm.

Revolutionizing Atrial Fibrillation Treatment: The Robotic Convergent Plus Procedure.

Atrial fibrillation (AF) is widely accepted to be the most common sustained arrhythmia, with an increasing incidence over time. This is thought to be due to the aging population across the world. AF occurs when abnormal electrical foci result in disorganization of atrial depolarization, though the exact pathophysiology leading to these abnormal foci is not well understood.

Sinus node sparing novel hybrid approach for treatment of inappropriate sinus tachycardia/postural sinus tachycardia: multicenter experience.

Background: The ideal treatment of inappropriate sinus tachycardia (IST) and postural orthostatic tachycardia syndrome (POTS) still needs to be defined. Medical treatments yield suboptimal results. Endocardial catheter ablation of the sinus node (SN) may risk phrenic nerve damage and open-heart surgery may be accompanied by unjustified invasive risks.

Safety and efficacy of leadless pacemaker for cardioinhibitory vasovagal syncope.

Background: Single-chamber leadless pacemakers (LPs) have been shown to be an effective alternative to conventional transvenous pacemakers (CTPs), but their benefit in the context of cardioinhibitory vasovagal syncope (CI-VVS) is unknown.

Objective: The purpose of this study was to evaluate the safety and efficacy of LP compared with dual-chamber CTP for CI-VVS.

Methods: We conducted a multicenter, retrospective study comparing patients who received LP or dual-chamber CTP for drug-refractory CI-VVS.

Utility of serial measurement of biomarkers of cardiovascular stress and inflammation in systolic dysfunction.

Aims: Evidence links markers of systemic inflammation and heart failure (HF) with ventricular arrhythmias (VA) and/or death. Biomarker levels, and the risk they indicate, may vary over time. We evaluated the utility of serial laboratory measurements of inflammatory biomarkers and HF, using time-dependent analysis.

Unrecognized venous injuries after cardiac implantable electronic device transvenous lead extraction.

Background: The major complication rate of transvenous lead extraction (TLE) is estimated to be 1%-2%. Laceration of the central veins can be fatal.

Objectives: To define the incidence and extent of venous injuries on a microscopic level after TLE and compare these data with those of clinically documented events of venous laceration.
