There was no significant difference between ventricular pressure, LV dP/dt or heart rate between groups. There was a significantly higher transvalvular pressure loss within both groups with the force transducers in situ corresponding to a mild stenosis. However, there was no significant difference in transvalvular pressure with the force transducers implanted between the 2 groups. The double-ring procedure itself caused a significant increase in transvalvular pressure loss compared with a single ring (double ring: 33 ± 17 mmHg; single ring: 21 ± 7 mmHg, P = 0.04). All pigs had no or trivial aortic insufficiency at any time during the procedure.","tracks":[]}
