Augmenting Mitral Valve Repair Evaluation with Intraoperative Left Ventricle Pressure Measurements

Surgical mitral valve repair is the gold standard treatment for mitral regurgitation due to degenerative disease. Repair is performed on the arrested heart, meaning that assessments of success can only be made after removal of cardiopulmonary bypass. The saline test remains an integral part of repair, however, its hemodynamics have not been evaluated. The authors present a simple technique to quantify the saline test. The authors note that the saline test may be less informative in cases where the maximum left ventricle diastolic pressure is low.
