Figure 1. Techniques used in ex vivo (A–E) and in vivo (F, G) studies (sheep)
After patch insertion, surgical views from the left atrium (A) or ventricle (B) and from the atrium after injection of pressurized water with prolapse (C). Echographic apical two-chamber views of the closed mitral valve before and after insertion (D) with AML billowing (*). Measurements of LV pressures and chordal tensions (sensor in yellow), while changes in pressure originate from aortic (AO) injections (arrow) (E). Echographic parasternal long-axis view in systole (F) showing AML billowing (*) after insertion. The sensors (in yellow) are sutured onto the strut chordae of the AML (G).
