To improve the prognosis of mitral valve replacement surgery, analysis and evaluation of pre and intra operative risk factors will be very much valuable. Author studied 205 cases of mitral valve replacement from Feb 1982 to June 1989 for the risk factors of hospital death. 90 patients were male and 115 were female, and age was from 16 to 59 years, Mitral stenosis dominant lesions were 91 cases and regurgitation 114. Suspected risk factors were NYHA functional class, cardiothoracic ratio, implanted valve type and size, operation time, age and sex, thrombus in left atrium, atrial fibrillation, aortic cross clamping time, left ventricular end diastolic and systolic dimension, nephropathy, hepatopathy and respiratory insufficiency. Statistic analysis was performed by X2 test between survivors and death group. Statistical significances as pre and intraoperative risk factors of hospital death after mitral valve replacement were confirmed in those presence of AF on the EKG, NYHA functional class[>IV], cardiothoracic ratio[>70%], and implanted valve size[>33mm]

Between Feb. 1982 and July 1990, 173 patients [male: 89, female: 84] Who underwent heart valve replacement for acquired valvular heart disease on the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Pusan National University, were reviewed for return to work after heart valve replacement. The replaced valve were mitral [128, 74.0%], aortic[10, 5.8%], mitral & aortic[35, 20.2%]. Two tricuspid valve replacement were excluded. Several important factors influencing the return to work were age, the employment status before surgery, the number of replaced valve, the pre - op NYHA functional class and cardiac function [ejection fraction]. These factors were closely related to the optimal time of heart valve replacement. It can be concluded that the rate of return to work and the quality of life would be improved if valve replacement were performed at an earlier stage of valvular heart disease.

Purpose: The purpose of this study was to investigate the effects of education and practice of the maternal role and becoming a mother using the concepts of self-confidence in caring, maternal attachment, and maternal identity. Methods: A non-equivalent control group non-synchronized design was used. Data was collected with the use of self-administered questionnaires from November 2007 to April, 2008. A total of 54 women at a Sanhujoriwon (postpartum care center) participated in the study. The experimental group consisted of 26 women (Nov-Dec), whereas the control group had 28 women (Feb-Apr). Education and practice on the maternal role was given individually and consisted of explanations, demonstrations and practice on breast feeding (day1 to 3), maternal attachment (day 8 to 9), bathing (day 10 to 11) and infant healthcare (day 13 to 14). The experimental group received education and practice on the maternal role while the control group received routine education only. Results: Data collection was done using pre and post questionnaires at admission and fourteen days later. The experimental group showed significant increases in self-confidence in caring (t=-3.31, p=.002) and maternal identity (t=-2.16, p=.036) compared to the control group. Conclusion: Education and practice on the maternal role and being a mother was an effective intervention in increasing self-confidence in caring and maternal identity.
