Hyper-response to cardiac resynchronization with permanent His bundle pacing: Is parahisian pacing sufficient?
نویسندگان
چکیده
The feasibility of resynchronizing ventricular activation by permanent pacing of the His bundle region has been previously described, and has clinical advantages over traditional right ventricular (RV) apical pacing.1–4 The physiologic benefit of permanent His bundle pacing (HBP) is the ability to stimulate the ventricles through the intrinsic His-Purkinje system, which results in synchronous electrical and mechanical activation. It also has theoretical advantages over cardiac resynchronization therapy (CRT) using a coronary sinus lead, which is associated with limited coronary venous anatomy and complications that include coronary sinus dissection, venous perforation, and the potential for proarrhythmia.

Permanent Parahisian Pacing
Right Ventricular Apical permanent pacing could have negative hemodynamic effects. A physiologic pacing modality should preserve a correct atrio-ventricular and interventricular synchronization. This can be obtained through biventricular pacing, left ventricular pacing, or from alternative right ventricular pacing sites. Direct His Bundle Pacing (DHBP) was documented as reliable and effective f...

There has been a recent upsurge of interest in permanent His bundle pacing, given increased understanding and appreciation of the role dyssynchronous ventricular activation plays in congestive heart failure and atrial fibrillation. Permanent His bundle pacing gives implanters the ability to avoid causing ventricular dyssynchrony in patients dependent on ventricular pacing, and can provide an al...

Heart failure (HF) is one of the biggest epidemics of modern cardiovascular medicine. Cardiac resynchronization therapy (CRT) with biventricular (BiV) pacing has proven to have an integral role in the management of patients with reduced left ventricular (LV) function and left bundle branch blocks (LBBB). However, CRT with BiV pacing is not always feasible and even when it is, the percentage of ...

Introduction Cardiac resynchronization therapy (CRT) has shown a significant clinical benefit over right ventricular pacing in patients with left ventricular dysfunction and a high ventricular pacing requirement. Traditionally, CRT has relied on coronary sinus (CS) lead placement through the use of fluoroscopy and venography. Three-dimensional (3D) electroanatomic mapping has been used as an al...
متن کاملSimultaneous His Bundle and Left Ventricular Pacing for Optimal Cardiac Resynchronization Therapy Delivery
The beneficial effects of cardiac resynchronization therapy (CRT) have been evaluated in several trials, and different degrees of response to CRT have been reported; indeed, the optimization of pacing sites and stimulation timing seems to be a major determinant of the hemodynamic response. For standard CRT delivery, the atrioventricular pacing interval is shortened to ensure consistent left ven...
