Abstract:
Objective To investigate the perioperative hemodynamic features of mitral replacement of patients with small left ventricle.Methods Patients with left ventricle end-diastolic dimension (LVEDD) less than 40mm received mitral replacement sur- gery were divided into big size M-2 group and small size M-1 group.The perioperative echo results were analyzed with SPSS software. Results The big size M-2 group has lower trans mitral gradient [ (5.9?1.6) mm Hg vs.(10.7?3.2) mm Hg],larger in vivo va- lular acre[ (2.9?0.2) cm~2 vs.(2.6?0.2) cm~2],and high mitral match index [(1.92?0.23) cm~2/m~2 vs.(1.73?0.18) cm~2/m~2 ].Conclusion With the meticulous perioperative treatment and myocardial protection,the patients with small left ventricle should also receive a mitral replacement as big as possible to achieve the ideal hemodynamics results.
