The current standard of care, known as biventricular pacing, uses two pacing impulses in both lower chambers, whereas the newer approach, called 'His bundle' pacing, attempts to work toward engaging and restoring the heart's natural physiology.
Successful implantation of a biventricular pacing and defibrillator device via a persistent left superior vena cava.
In the Wireless Stimulation Endocardially for CRT (WiSE-CRT) study, preliminary results showed the system improved left ventricular function at 6 months; however, the study was terminated prematurely due to safety concerns including inability to successfully implant the device, pericardial effusions due to device delivery technique, loss of biventricular pacing, and depletion of the battery (22).
Biventricular pacing / cardiac resynchronization therapy (CRT) may improve clinically significant and progressive morbidity associated with concomitant congestive heart failure.2 Left Ventricular (LV) dyssynchrony is an important mechanism which plays a pivotal part in progression of heart failure and ventricular remodeling.
Effects of biventricular pacing on interstitial remodelling, tumor necrosis factor-alpha expression, and apoptotic death in failing human myocardium.
ICD right ventricular (RV) pacing was upgraded to biventricular pacing with a cardiac resynchronization therapy defibrillator (CRTD) (Viva[TM] XT; Medtronic, NJ, USA) (height 72 cm, weight 8.5 kg).
In refractory congestive heart failure (CHF) accompanied by left bundle branch block (LBBB), cardiac resynchronization therapy (CRT) with biventricular pacing has been shown to be associated with better outcomes and has been established as an adjunctive heart failure treatment (13).
Although other lead-less pacemakers have been developed, their form factors limit them to a single heart chamber, and they are unable to provide dual-chamber or biventricular pacing. In contrast, battery-less, lead-less, and wirelessly powered microchips can be implanted directly to pace multiple points inside or outside the heart.
In these patients upgrading to biventricular pacing should be considered in patients requiring permanent or frequent right ventricular pacing for bradycardia, who have symptomatic heart failure and low left ventricular ejection fraction [12].
standard biventricular pacing. Patients treated with AdaptivCRT experienced a 35 percent reduction in the subsequent development of AF compared to patients treated with standard biventricular pacing.
Although an implantable cardioverter defibrillator (CRTD, Cardiac Resynchronization Therapy-Defibrillation), with biventricular pacing function, was replaced with PM for severe left ventricular functional decline, on day 12 of admission, an intra-aortic balloon pump (IABP) was also inserted because of multiple organ failure.
