Long-term prognosis and prognostic factors after primary prophylactic implantable cardioverter-defibrillator therapy
CONCLUSIONS: Prior NSVT before ICD implantation was not an independent predictor of future MACE in patients with HFrEF with primary prophylactic ICD. In contrast, atrial fibrillation was associated with worse prognosis. To predict the prognosis of patients with primary prophylactic ICD, these factors should be assessed as comprehensive risk stratification factors for MACE.PMID:38382578 | DOI:10.1016/j.jjcc.2024.02.006 (Source: Journal of Cardiology)

Role of speckle tracking echocardiography beyond current guidelines in cardiac resynchronization therapy
Cardiac resynchronization therapy (CRT) is a device-based treatment applied to patients with a specific profile of heart failure. According to current guidelines, indication for CRT is given on the basis of QRS morphology and duration, and traditional transthoracic echocardiography is mainly used to estimate left ventricular (LV) ejection fraction. However, the identification of patients who may benefit from CRT remains challenging, since the application of the above-mentioned guidelines is still associated with a high rate of non-responders.

A step forward towards conduction system pacing –based cardiac resynchronization therapy, albeit a small one.
Starting from the very first clinical reports of the deep septal pacing technique by Mafi-Rad et al. and Huang et al., it became clear that the activation of the left ventricle (LV) during pacing near the left conduction system (the method known as left bundle branch area pacing – LBBAP) results in paced QRS that, in contrast to the conventional right ventricular pacing technique, has none of the features of left bundle branch block.1;2 On the contrary, the reported LBBAP paced QRS complexes showed rapid activation over the LV and demonstrates right bundle branch block pa ttern.

Efficacy of Left Bundle Branch Area Pacing Versus Biventricular Pacing in Cardiac Resynchronization Therapy Patients: Select Site - Cohort Study
Cardiac resynchronization therapy (CRT) is typically attempted with biventricular pacing. One-third of patients are non-responders. Left bundle branch area pacing (LBBAP) has been evaluated as an alternative means. (Source: Heart Rhythm)

Clinical Utility of QRS Duration Normalized to Left Ventricular Volume for Predicting Cardiac Resynchronization Therapy Efficacy in Patients with "Mid-Range" QRS Duration
Cardiac resynchronization therapy (CRT) is effective for patients with heart failure with a QRS duration (QRSd)> 150 milliseconds (ms). However, its beneficial effect appears to be limited for those with a "mid-range" QRSd (120 –149 ms). Recent studies have demonstrated that modifying the QRSd to left ventricular end-diastolic volume (LVEDV), modified QRSd, improves the prediction of clinical outcomes of CRT. (Source: Heart Rhythm)

Challenges and pitfalls during CRT implantation in patients with persistent left superior vena cava
ConclusionsThis case series shows that although challenging, conventional endovascular CRT implantation is feasible in PLSVC patients. Specialized tools for visualization and fixation may help. Our experiences highlight the importance of preprocedural evaluation of the anatomy and precise intervention planning.Graphical Abstract (Source: Journal of Interventional Cardiac Electrophysiology)
