We report the placement of a permanent transvenous nonselective His bundle pacing lead in conjunction with a transvenous pacemaker/ICD in an adult with Levo-Transposition of the Great Arteries (L-TGA) and a stenotic coronary sinus (CS) ostium (os), which would not accommodate a transvenous LV pacing lead. Nonselective His bundle pacing provided a nearly identical ventricular activation pattern in this previously unpaced patient. Many L-TGA patients will have an eventual need for permanent pacing and, given the challenges of CS cannulation, His bundle pacing may represent a preferred modality rather than pure morphologic LV pacing or surgical systemic ventricular lead placement to achieve optimal electrical synchrony...

Aims: His bundle pacing has shown to prevent detrimental effects from right ventricular apical pacing (RVA) and proved to resynchronize many conduction disturbances cases. However, the extent of His bundle pacing resynchronization is limited. An optimized stimulation waveform could expand this limit when implemented in His bundle pacing sets. In this work, we temporarily implemented RVA and Non-selective His bundle pacing with a biphasic anodal-first waveform (AF-nHB) and compared their effects against sinus rhythm (SR)...

Aims: Shortening of the atrial-His bundle (AH) interval during the sinus rhythm is occasionally observed after slow pathway ablation for atrioventricular nodal re-entrant tachycardia (AVNRT). In addition, high-rate atrial pacing is useful for avoiding atrioventricular block. We hypothesized that shortening of the AH interval during slow pathway ablation under high-rate atrial pacing would lead to successful ablation of typical AVNRT. Methods and results: This retrospective study included 37 patients in whom successful ablation of typical AVNRT was performed under atrial pacing...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

There have been many milestones in the evolution of cardiac implantable electronic devices (CIEDs) over the past few decades. Along with advancements in the field, new challenges have arisen. The ability to pace the right ventricular was the original breakthrough in the late 1950s, however adverse structural and clinical effects of long-term pacing induced dyssynchrony have recently become evident. Biventricular pacing has provided a viable option to help mitigate dyssynchrony, but has only proved to be beneficial for selective patients (primarily left bundle branch block and QRS duration ≥ 150 ms with depressed left ventricular (LV) function)...

This review will focus on the feasibility of long term His bundle pacing and its effects on left ventricle (LV) hemodynamics. Compared with right ventricular pacing, His bundle pacing results in a more physiological electro-mechanical activation that contributes to preserve LV function. Moreover some studies showed a similar effect to biventricular pacing in patients with heart failure and left bundle branch block. Recent observations indicate that His bundle pacing should be considered as an optimal site to pace right ventricle in patients who are candidates for cardiac resynchronization therapy...

Long-term right ventricular (RV) apical pacing has been associated with an increased risk of death, heart failure, and atrial fibrillation (AF). Alternative sites for RV pacing have not proven to be superior to RV apical pacing. Cardiac resynchronization therapy (CRT) using a biventricular (BiV) lead system is indicated for patients with a low left ventricular ejection fraction and QRS prolongation, but there remains about a 25-30% nonresponse rate. CRT has been less effective for nonleft bundle branch block conduction delay and with normal/low normal left ventricular function...

Biventricular pacing has occasionally been associated with ventricular proarrhythmia, which at times can be refractory to conventional antiarrhythmic drug therapy and ablative intervention. Recently, permanent His-bundle pacing has emerged as a reasonable alternative to right ventricular and biventricular pacing. In addition, by maintaining the physiologic pattern of ventricular electrical activation, it is less likely to be arrhythmogenic. We report the use of permanent His-bundle pacing to manage ventricular proarrhythmia that developed after initiation of biventricular pacing and was unresponsive to antiarrhythmic and ablative therapy...

Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alternative to BiVP. We present a patient with PICM who responded dramatically to permanent HBP.

Cardiac resynchronization therapy (CRT) has an established role in the device-based therapy for patients with systolic dysfunction and intraventricular conduction delay, particularly left bundle branch block (LBBB). Recently, His bundle pacing (HBP) has emerged as a viable alternative for resynchronization which can successfully narrow surface QRS and improve mechanical dyssynchrony. The role of selective (i.e., an isoelectric His-paced to QRS interval similar to native HV interval) versus non-selective capture (i...

Synchronized left ventricular pacing (sLVP) via adaptive cardiac resynchronization therapy (aCRT) algorithm might enhance the efficacy of CRT. A 71-year-old female was admitted with the diagnosis of heart failure. Electrocardiograms revealed left bundle branch block with QRS width of 144 ms, and frequent premature ventricular complexes (PVCs). A CRT device was implanted, and sLVP via a CRT algorithm was provided. Frequent PVCs arising from the His-bundle suppressed effective sLVP percentage. Radiofrequency application at the His-bundle successfully eliminated the PVCs, but induced complete atrioventricular (AV) block, leading to loss of sLVP...

This study evaluated hemodynamic feasibility and reproducibility of a new method for in vivo simulation of human atrial fibrillation (AF). The method was tested during sinus rhythm in 10 patients undergoing catheter ablation for AF. A simple electronic device was assembled that allowed triggering a cardiac stimulator by predefined series of RR intervals. Irregular RR interval sequences with a mean heart rate of 90/min and 130/min were obtained from ECG recordings of another patients with AF. Simultaneous atrioventricular pacing was delivered by catheters placed inside the coronary sinus and at the His bundle region...

Chronic right ventricular (RV) pacing has been shown over the years to exert detrimental physiological changes including increased risk for heart failure and atrial fibrillation. His bundle pacing offers the promise of physiological activation of the ventricular tissue, with the potential for reducing the detrimental effects of RV pacing. We describe His bundle pacing in a historical context and briefly highlight several clinical trials that have helped shape the landscape of permanent His bundle pacing.

Direct His bundle pacing provides the most physiologic means of artificial pacing of the ventricles with a preserved His-Purkinje system and may play a role in patients with a diseased intrinsic conduction system. We describe our initial motivations and experience with permanent direct His bundle pacing and important lessons learned since that time.

Adverse hemodynamics of right ventricular (RV) pacing is a well-known fact. It was believed to be the result of atrio-ventricular (AV) dyssynchrony and sequential pacing of the atrium and ventricle may solve these problems. However, despite maintenance of AV synchrony, the dual chamber pacemakers in different trials have failed to show its superiority over single chamber RV apical pacing in terms of death, progression of heart failure, and atrial fibrillation (AF). As a consequence, investigators searched for alternate pacing sites with a more physiological activation pattern and better hemodynamics...
