NCT ID: NCT06138873 Not yet recruiting - Clinical trials for Ventricular Tachycardia

Ablation-Index Guided Scar-Mediated Ventricular Tachycardia Ablation in Patients With Ischemic Cardiomyopathy

AIM-VT
Start date: July 1, 2024
Phase: N/A
Study type: Interventional

Over the last decade, radiofrequency catheter ablation (RFCA) has become an established treatment for ventricular arrhythmias (VA). Due to the challenging nature of visualizing lesion formation in real time and ensuring an effective transmural lesion, different surrogate measures of lesion quality have been used. The Ablation Index (AI) is a variable incorporating power delivery in its formula and combining it with CF and time in a weighted equation which aims at allowing for a more precise estimation of lesion depth and quality when ablating VAs. AI guidance has previously been shown to improve outcomes in atrial and ventricular ablation in patients with premature ventricular complexes (PVC). However research on outcomes following AI-guidance for VT ablation specifically in patients with structural disease and prior myocardial infarction remains sparse. The investigators aim at conducting the first randomized controlled trial testing for the superiority of an AI-guided approach regarding procedural duration.

NCT ID: NCT05760924 Not yet recruiting - Heart Failure Clinical Trials

Left Bundle Branch Pacing on Outcomes and Ventricular Remodeling in Biventricular CRT Nonresponders

RESCUE
Start date: May 1, 2024
Phase: N/A
Study type: Interventional

Heart failure (HF) is the most common nosology encountered in clinical practice. Its incidence and prevalence increase exponentially with increasing age and it is associated with the increased mortality, more frequent hospitalization and decreased quality of life. An initial approach to the treatment of HF patients with reduced left ventricular (LV) systolic function and left bundle branch block (LBBB) was implantation of device for cardiac resynchronization therapy using biventricular pacing. This has resulted in long-term clinical benefits such as improved quality of life, increased functional capacity, reduced HF hospitalizations and overall mortality. However, conventional cardiac resynchronization therapy (CRT) is effective in only 70% of patients. And the remaining 30% of patients are non-responders to conventional CRT. Cardiac conduction system pacing is currently a promising technique for these patients. Particularly, His bundle pacing (HBP) has been developed to achieve the same results. According to other studies HBP has shown greater improvement in hemodynamic parameters comparing with conventional biventricular CRT. But, nevertheless, there are significant clinical troubles with HBP, especially high pacing threshold. In this regard, in 2017, the left bundle branch pacing (LBBP) was developed, which demonstrated clinical advantages compared to conventional biventricular CRT. Also, since 2019, left bundle branch pacing-optimized CRT (LBBPO CRT) has been used in clinical practice. These methods have become an alternative to HBP due to the stimulation of LBB outside the blocking site, a stable pacing threshold and a narrow QRS complex duration on electrocardiogram. A series of case reports and observational studies have demonstrated the efficacy and safety of LBBP and LBBPO CRT in patients with CRT indications. However, it is not enough data about impact of CRT with LBBP and combined CRT with LBBP and LV pacing on myocardial remodeling, reducing mortality and complications. According to our hypothesis, CRT with LBBP and combined CRT with LBBP and LV pacing compared with conventional biventricular pacing will significantly improve the clinical outcomes and reverse myocardial remodeling in patients who are non-responders to biventricular CRT with HF, reduced LV ejection fraction and with indications to CRT devices with defibrillator function (CRT-D) or one of the CRT-D leads replacement.

European Sleep Apnea and Sudden CArdiac Death ProjEct

ESCAPE-SCD
Start date: January 2016
Phase: N/A
Study type: Interventional

The objective of ESCAPE-SCD Study is assessment of the effect of sleep apnea on sudden cardiac death risk and cardiovascular outcomes in patients with ischemic cardiomyopathy. The ESCAPE - SCD Study will address following specific study questions: - Is obstructive sleep apnea (OSA) and/or central sleep apnea (CSA) an independent risk factor of sudden cardiac death (SCD) in patients with ischemic cardiomyopathy (ICM) indicated for ICD/CRT-D implant based on current European Society of Cardiology (ESC) Guidelines for primary prevention of sudden cardiac death? - Can treatment of predominant (>50%) obstructive sleep apnea by appropriate Positive Airway Pressure (PAP) therapy decrease risk of sudden cardiac arrhythmic death in ICM patients? - Can treatment of predominant (>50%) obstructive sleep apnea by appropriate PAP therapy improve cardiovascular outcomes in ICM patients indicated for ICD/CRT-D implant? - Does obstructive sleep apnea represent a novel factor that may improve risk stratification of sudden cardiac death and advance identification of those patients that will benefit from ICD/CRT-D therapy?
