Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

This study aims to survey patients who underwent a heart valve so as to define their self-care Agency and quality of life, as well as the effect of their self-care Agency on their quality of life. One hundred ten outpatients in two university hospitals in the City of D were surveyed using a structured questionnaire. The findings of this study revealed that for the life quality of patients with a surgery of heart valve, out of a total of 4.0 points, self-care Agency was an average 2.71 points, while life quality was an average 2.96 points, showing not so high scores. Also, it was also found that the higher the physical skills of patients with a surgery of heart valve (${\beta}$=.625, p<.001) were, the higher the quality of their life was. In conclusion, self-care Agency was confirmed as a determinant of the life quality of patients with a surgery of heart valve, and it was found that the higher the self-care Agency of patients with a surgery of heart valve, the higher their life quality was. Thus, in order to enhance the self-care Agency of patients with a surgery of heart valve, nursing assessment of their physical, psychological and mental areas, as well as corresponding appropriate nursing interventions need to be developed.

Background: Heart transplantation is considerated for a selected certain group of complicated congenital heart disease in neonates because corrective surgery is very difficult and has high mortality. Precise planning of transplantation is necessary to adequately fit the donor heart to the recipient. Material and Method: We have performed 4 neonatal pig heart transplantations to test the technical feasibility. Experiment 1: The transplantation was performed using the same technique as the adult heart transplantation. Experiment 2: The transplantation for hypoplastic left heart syndrome was simulated as we reconstructed the whole aortic arch with donor aorta. Experiment 3: The heart transplantation was done with radical pulmonary artery reconstruction. Experiment 4: The experiment was performed for a long term survival. Result: Preoperative planning was very important for adequate fitting. All animals could be weaned from cardiopulmonary bypass, however, two animals died due to bleeding at pulmonary artery and left atrium. Conclusion: We concluded that the neonatal heart transplantation can be applied in some complicated Further using animal model is mandatory.

Background: The interest in robotic cardiac surgery has recently grown but there has not been much clinical research reported on this. The aim of this study is to examine our initial experience, since August 2007, with robotic cardiac surgery using the da $Vince^{TM}$ surgical system and to evaluate the feasibility and safety of it. Material and Method: Between August and December 2007, a total of 20 patients underwent robotic cardiac surgery using the da Vinci surgical system. For mitral valve repair (n=11), tricuspid valve repair (n=1), and ASD repair (n=1), cannulation, antegrade cardioplegia and transthoracic aortic cross-clamping were conducted for the right femoral vessels and the right internal jugular vein. For minimally invasive direct CABG (MIDCAB) (n=7), the internal thoracic artery (ITA) was harvested with the da Vinci surgical system. Result: The mean age of the patients was 50.1 (range: $26{\sim}78$) years. Three concomitant Maze procedures and one tricuspid annuloplasty were combined with mitral valve repair. The mean cardiopulmonary bypass time was $208.0{\pm}61.3$ minutes and the aortic cross clamp time was $158.8{\pm}40.6$ minutes. No patients showed more than mild mitral regurgitation after repair and the median hospital stay was 4 days. The robotic-harvested ITA was used for either left ITA (n=6) or bilateral ITA (n=1). The mean harvest time was $43.2{\pm}12.0$ minutes. The harvested ITA showed good flow and it was anastomosed under direct vision after left anterolateral thoracotomy. The patency of all the grafts was 100% (18/18) in MIDCAB. Conclusion: Robotic cardiac surgery using the da Vinci surgical system was variously adapted to areas such as mitral and tricuspid valve repair, ASD repair and ITA harvest for MIDCAB. The early results of the robotic cardiac surgery showed its safety and feasibility. With this primary report, we anticipate that clinical applications and further studies on robotic cardiac surgery using the da Vinci surgical system will be actively conducted in Korea.

Systemic lupus erythemotosus (SLE) is an autoimmune disorder with dermal, renal, and cardiac manifestations. It frequently has cardiovascular complications such as pericarditis, myocarditis, and valvular heart diseases. Valvular heart diseases in SLE comes mainly in the form of mitral or aortic insufficiencies. Report of aortic stenosis is extremely rare. Surgical treatments of valvular heart disease in SLE are not done frequently because of complications in other organs. Aortic stenosis developed in a 59 year-old woman with SLE, and aortic valve replacement was done successfully.
