BACKGROUND: Right ventricular pacing (RVP) is associated with an increased incidence of heart failure and may impair cardiac function. Permanent His bundle pacing (HBP) has the potential to physiologically preserve and prevent cardiac dysfunction. This study was to evaluate the feasibility and intermediate follow-up results of upgrade to HBP implantation in patients referred for pulse generator change with long term RVP. METHODS: Twelve of 14 pacing dependent patients who were referred for pulse generator exchange underwent upgrade into HBP successfully in our center...

From 1993 to 2009, nearly 2.9 million pacemakers were implanted in the United States; the majority of which were dual chamber pacemakers. One of the major physiologic advantages of dual chamber pacing over single chamber ventricular pacing is atrioventricular synchrony, which prevents the pacemaker syndrome. However, patients who are pacemaker dependent or use right ventricle (RV) apical pacing more than 40% of the time are at a risk of developing heart failure from electromechanical dyssynchrony. Studies have also shown that RV pacing results in non-physiological activation of the left ventricle, leading to adverse clinical outcomes...

BACKGROUND Lown-Ganong-Levine syndrome, includes a short PR interval, normal QRS complex, and paroxysmal tachycardia. The pathophysiology of this syndrome includes an accessory pathway connecting the atria and the atrioventricular (AV) node (James fiber), or between the atria and the His bundle (Brechenmacher fiber). Similar features are seen in enhanced atrioventricular nodal conduction (EAVNC), with the underlying pathophysiology due to a fast pathway to the AV node, and with the diagnosis requiring specific electrophysiologic criteria...

BACKGROUND: Right ventricular pacing (RVP) is associated with heart failure and increased mortality. His bundle pacing (HBP) is a physiological alternative to RVP. OBJECTIVE: The aim of the study is to evaluate clinical outcomes of HBP compared to RVP. METHODS: All patients requiring initial pacemaker implantation between Oct 1st , 2013 and December 31st , 2016 were included in the study. Permanent HBP was attempted in consecutive patients at one hospital and RVP at a sister hospital...

CRT is a therapeutic option for patients with heart failure, sinus rhythm, prolonged QRS complex duration and reduced ejection fraction. We present a case of 71-year-old woman with dilated cardiomyopathy, NYHA functional class III and AF. We implanted CRT combined with direct His-bundle pacing. The indication for such a therapy was a left bundle branch block with a QRS complex of 178ms and a left ventricular EF of 15%, left ventricular end-diastolic diameter (LVEDD) of 75mm. After 8months of follow-up the LVEDD was 60mm with EF 35-40%...

Cardiac resynchronization therapy (CRT) is an important therapeutic tool in the management of patients with heart failure and electrical dyssynchrony. In appropriately selected patients, landmark randomized controlled trials have demonstrated morbidity and mortality benefit beyond standard goal-directed medical therapy. Current guidelines emphasize the greatest clinical efficacy of CRT in patients with symptomatic heart failure, left bundle branch block, and wide QRS duration (> 150 ms). Other relevant considerations include the presence of atrial fibrillation, the presence of AV block, the etiology of cardiomyopathy, the presence of masked left-sided conduction delay, and the impact of comorbidities that might predict poor clinical response...

His bundle pacing (HBP) has been shown to be a feasible, beneficial, and safe way to achieve cardiac resynchronization therapy (CRT) with recruitment of the heart's physiological conduction system. HBP should be considered for those with unfavorable coronary sinus (CS) anatomy, and nonresponders to biventricular (BiV) pacing. HBP CRT may also help patients with the nonleft bundle branch block form of conduction delay and heart failure (HF). HBP CRT should be considered strongly in preventing right ventricular (RV) pacing-induced cardiomyopathy, especially after atrioventricular nodal ablation given the discrete nature of the block and the low likelihood of distal block...

Cardiac resynchronization therapy (CRT) is a well-established treatment for symptomatic heart failure patients with reduced left ventricular ejection fraction, prolonged QRS duration, and abnormal QRS morphology. The ultimate goals of modern CRT are to improve the proportion of patients responding to CRT and to maximize the response to CRT in patients who do respond. While the rate of CRT nonresponders has moderately but progressively decreased over the last 20 years, mostly in patients with left bundle branch block, in patients without left bundle branch block the response rate is almost unchanged...

A 35-year old lady was referred for evaluation of recurrent palpitation. During one of the episodes of palpitation a wide QRS tachycardia with left bundle branch block (LBBB) morphology was recorded and it was terminated with intravenous adenosine. The surface electrocardiogram during sinus rhythm did not show any pre-excitation. Echocardiogram was normal. Patient underwent an electrophysiology study after informed consent. During catheter placement a wide QRS tachycardia with LBBB morphology and left axis deviation (LAD) similar to the clinical tachycardia got induced (Fig:1)...

Long-term right ventricular apical pacing has been associated with detrimental effects, including an increased risk for heart failure, atrial fibrillation, and death. Most of these adverse effects result from ventricular dyssynchrony related to perturbed ventricular depolarization. In addition, biventricular pacing has limited benefits in patients with non-left bundle branch block and severely reduced ejection fraction. Consequently, alternative pacing strategies that mimic natural physiology are desired. Recently, permanent His bundle pacing has emerged as a true physiologic form of ventricular pacing that has been shown to be safe and feasible in clinical practice...

Subclavian obstruction is common after lead implantation and the need to add or replace a lead is increasing. Subclavian venoplasty (SV) is a safe and effective option for venous occlusion. Peripheral venography overestimates the severity of the obstruction. A wire can usually be advanced into the central circulation for SV. Compared with dilators, SV improves the quality of venous access, providing unrestricted catheter manipulation for His bundle pacing and left ventricular lead implantation. SV preserves venous access and reduces lead burden...

A man with non-ischemic cardiomyopathy, EF 22%, permanent AF and ICD was admitted for elective device replacement. The need for the optimization of the ventricular rate and avoidance of right ventricular pacing made it necessary to up-grade the existing pacing system using direct His bundle pacing and dual chamber ICD. This enabled the regularization of ventricular rate, avoiding the RV pacing and optimize the beta-blocker dose. The one month follow-up already showed reduction in left ventricle diameter, improvement in ejection fraction, NYHA class decrease to II...

Aims: Atrioventricular node ablation (AVNA) and right ventricular pacing (RVP) are effective therapies for patients with atrial fibrillation (AF) and rapid ventricular rates. His bundle pacing (HBP) is a physiologic alternative to RVP. The aim of our study is to assess the feasibility and safety of HBP in patients undergoing AVNA and its effect on left ventricular (LV) function. Methods and results: Permanent HBP is the preferred form of ventricular pacing at our institute...

This report demonstrates the feasibility of pacing the left bundle branch (LBB) immediately beyond the conduction block to functionally restore the impaired His-Purkinje conduction system in a patient with heart failure and left bundle branch block (LBBB). The pacing required only a low pacing output (0.5 volts/0.5 ms) to correct the LBBB with accompanying right BBB on the electrocardiogram. Over 1-year of follow-up, the patient had a significant improvement in clinical outcome and echocardiographic measurements...
