Presentation at European Society of Cardiology demonstrates VIVO accuracy in complex ventricular tachycardia patients – Catheter Precision Inc

Catheter Precision, Inc. announced that at the recently held European Society of Cardiology (ESC) Symposium, interim results demonstrating the use of VIVO in localizing the site of origin of ventricular tachycardia (VT) for patients with scar related re-entrant VT were presented. Additionally, the presentation showed the relationship to the relevant myocardial scar on cross-sectional imaging from the CT scan.

The study, ongoing at the Warwick Medical School at the University Hospitals of Coventry and Warwickshire is ongoing with lead investigator Professor Tarv Dhanjal. The presentation was entitled “Accuracy of a non-invasive mapping system for the localization of re-entrant VT site of origin and its relationship to myocardial scar on cross-sectional imaging”.

The interim results were presented on twenty patients with structural heart disease and a mean ejection fraction of 35.5 and included patients with ischemic cardiomyopathy, dilated cardiomyopathy, and hypertrophic cardiomyopathy. The results showed a VIVO accuracy of 90% as compared to invasive mapping, performed with the Abbott Advisor HD Grid multipolar catheter. VIVO non-invasive mapping showed a significant match especially in the area of myocardial scar in these patients. At a mean follow up of seven months, procedural success has been noted in 90% of the patients.

David Jenkins, CEO of Catheter Precision, commented, “These are significant results shown in very sick post heart attack patients with scarred heart muscle and structural heart disease. We look forward to the enrollment of additional patients and the conclusion of the study. We are hopeful that the results and continued research will bring about additional indications for use here in the US. As well, we are hopeful that the VIVO technology will be seen as a very useful tool in treating this expanded group of patients in need of state-of-the-art medical care.”
