Premature Ventricular Contractions clinical trials at University of California Health
2 in progress, 0 open to eligible people
Sorry, accepting new patients by invitation only
This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.

Premature ventricular contractions (PVCs) coexist in patients with heart failure (HF) and LV dysfunction. Frequent PVCs have shown to induce a reversible cardiomyopathy (PVC-CM). This clinical pilot study will enroll 36 patients with frequent PVCs (burden >10%) and CM (LVEF <45%) and randomize them to either: 1) RFA or 2) AADs. Prior to treatment, patients will undergo a baseline cardiac MR if clinically indicated followed by 3-month observation period (optimal HF medical therapy). Changes in LV function/scar, PVC burden/arrhythmias and clinical/functional status (QOL, HF symptoms and admissions, NYHA class) and adverse events will be assessed throughout the observation period and compare with PVC suppression strategies (RFA or AAD). Similar comparison will be made between RFA and AAD treatment groups during a 12-month follow up using a Prospective Randomized Open, Blinded End-point (PROBE) study design. The treatment regimens will be compared in an intention-to-treat analysis. In addition, a total of 20,000 consecutive ambulatory ECG Holter monitors from all participating centers will be screened to identify all patients with probable diagnosis of PVC-CM. This pilot study is intended to estimate the prevalence of this clinical entity and pave the way for a large full scale randomized trial to identify best treatment strategy for patients with PVC-CM. Treating and reversing this underestimated PVC-CM may improve patient's health and subsequently decrease HF healthcare spending.
