Comparison of Complications After Valve Replacement in Patients With Enlarged or Small Left Ventricles / 中国循环杂志

ABSTRACT

Objective:To summarize the experience of surgical treatment of valvular heart disease with enlarged or small left ventricles. Methods:Valvular operations were performed in 473 patients,including 38 with enlarged left ventricles(group Ⅰ)and 40 with small left ventricles(group Ⅱ),from April 1998 to June 2005.Postoperative complications between two groups were com- pared and analyzed statistically. Results:The postoperative eomplications were ventricular arrhythmia,low output syndrome,lung infection,renal failure and brain embolism.Low output syndrome tended to occur in group Ⅱ(20%),whereas there was a higher incidence of ventricular ar- rhythmia in group Ⅰ(65.79%).The difference between groups was significant(P＜0.05). Conclusion:To improve the successful operative rate in patients with enlarged or small left ventricles,we should take effec- tive measures to manage the post-procedural complications,such as ventricular arrhythmia(mainly in group Ⅰ)and low output syndrome(mainly in group Ⅱ).
