Permanent Left Bundle Branch Area DF-4 Defibrillator Lead Implantation-Feasibility, Procedural Caveats, Safety, and Follow-Up.

Introduction: Permanent implantation of a DF-4 implantable cardiac defibrillator (ICD) lead in the left bundle branch area (LBBA-ICD) is the next paradigm in amalgamating cardiac resynchronization therapy (CRT) and defibrillation. We systematically investigated feasibility/success rate, procedural caveats, and complications associated with a permanent DF-4 LBBA ICD implant and pertinent data at short-term follow-up.
Methods: We prospectively attempted implantation of 7 Fr Durata (Abbott, Chicago, IL, USA) single coil DF-4 ICD lead at the LBBA using a fixed-curve non-deflectable CPS locator delivery sheath.
Gated myocardial perfusion SPECT for evaluating left ventricular dyssynchrony in cardiac resynchronization therapy candidates: a systematic review.

Objectives: Cardiac resynchronization therapy (CRT) is an intervention for heart failure patients with reduced ejection fraction who exhibit specific electrocardiographic indicators of electrical dyssynchrony. However, electrical dyssynchrony does not universally correspond to left ventricular mechanical dyssynchrony (LVMD). Gated single-photon emission computed tomography (SPECT) myocardial perfusion allows for the assessment of LVMD, yet its role in the CRT selection process remains debated.

More than 1 million permanent pacemakers are implanted worldwide each year, half of which are in patients with high-grade atrioventricular block. Pacemakers provide adequate frequency support in the initial stage, but traditional right ventricular (RV) pacing may lead to or aggravate left ventricular dysfunction and arrhythmia. Several potential risk factors for heart failure and arrhythmias after pacemaker surgery have been identified, but their occurrence remains difficult to predict clinically.

The integrative physiology of the left ventricle and systemic circulation is fundamental to our understanding of advanced heart failure and cardiogenic shock. In simplest terms, any increase in aortic stiffness increases the vascular afterload presented to the failing left ventricle. The net effect is increased myocardial oxygen demand and reduced coronary perfusion pressure, thereby further deteriorating contractile function.

Objective: To evaluate systematically the feasibility and effectiveness of His Bundle Pacing (HBP) for cardiac resynchronization therapy.
Methods: A comprehensive search was conducted in PubMed, EMbase, WOS, Cochrane Library, Medline, and SinoMed for studies published between December 2003 and December 2023. Primary clinical outcomes included implantation success, QRS wave duration, pacing threshold, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), New York Heart Association (NYHA) cardiac function class, and complications.
