SVR Clinical Research

Surgical Ventricular Restoration (SVR) Clinical Research

Brief Summary of Current SVR Research

A five-year international trial of 1,198 SVR patients1 provides compelling evidence that SVR is a safe and effective treatment for certain types of congestive heart failure.

In the study, overall five-year freedom from readmission to the hospital with heart failure was 78 percent.

By comparison, the annual hospital admission rate for Class III and IV heart failure patients is more than 40 percent and 24 percent are admitted two or more times each year.2

In addition, post-operative ejection fraction increased from 30 to 40 percent and left ventricular end systolic volume index decreased from 80 to 57 ml/m2.

This shows the value of reducing ventricular volume intraoperatively by changing ventricular geometry of patients with heart failure. These results were achieved with patch-related closure in most cases, and with direct closure without a patch in some instances.
