Mitral Valve Holes Angioplasty Experimental And Clinical Studies

Objective: To observe the change of hydrodynamics on test table after double-orifice in swines; Compare the change of hemodynamics underthrough double orifice to the change of hemodynamics underthrough mitral replacement and to the change of hemodynamics underthrough other mitral repair operation. To investigate the feasibility of double orifice operation in mitral incompetence.Methods: Experiment part: select 15 fresh swine hearts and incise the hearts between the right coronary aortic valve and noncoronary valve. Cut the anterolateral papillary muscle(ALPM) and posteromedial papillary muscle (PMPM) after mitral exposed , dissect the...
