OBJECTIVE: The aims of this study were to compare opening and closing angles of normally functioning mechanical aortic valves measured on dual-source computed tomography (CT) with the manufacturers' values and to compare CT-measured opening angles according to valve function. MATERIALS AND METHODS: A total of 140 patients with 10 different types of mechanical aortic valves, who underwent dual-source cardiac CT, were included. Opening and closing angles were measured on CT images. Agreement between angles in normally functioning valves and the manufacturer values was assessed using the interclass coefficient and the Bland-Altman method. CT-measured opening angles were compared between normal functioning valves and suspected dysfunctioning valves. RESULTS: The CT-measured opening angles of normally functioning valves and manufacturers' values showed excellent agreement for seven valve types (intraclass coefficient [ICC], 0.977; 95% confidence interval [CI], 0.962-0.987). The mean differences in opening angles between the CT measurements and the manufacturers' values were 1.2degrees in seven types of valves, 11.0degrees in On-X valves, and 15.5degrees in ATS valves. The manufacturers' closing angles and those measured by CT showed excellent agreement for all valve types (ICC, 0.953; 95% CI, 0.920-0.972). Among valves with suspected dysfunction, those with limitation of motion (LOM) and an increased pressure gradient (PG) had smaller opening angles than those with LOM only (p < 0.05). CONCLUSION: Dual-source cardiac CT accurately measures opening and closing angles in most types of mechanical aortic valves, compared with the manufacturers' values. Opening angles on CT differ according to the type of valve dysfunction and a decreased opening angle may suggest an elevated PG.

OBJECTIVES: To assess the clinical features, pathologic findings, postoperative results and the effects of immunosuppressive therapy in patients with Beh et's disease (BD). METHODS: We reviewed the postoperative course of the 9 BD patients who underwent a total of 17 aortic valve replacement procedures with prosthetic valves. RESULTS: Histological examination of the aortic valve commonly revealed diffuse myxoid degeneration (75 percent). Of 17 valve replacement surgeries, 13 surgeries resulted in complications, such as detachment of the prosthetic valve with perivalvular leakage and dehiscence of the sternotomy wound, within an average of 5 months (range from 1 month to 14 months). The rate of prosthetic valve detachment was 76 percent (13 of 17 surgeries). Four of the 9 patients (44 percent) who underwent aortic valve replacement procedures died of heart failure or infection associated with the detachment of the prosthetic valve, and perivalvular leakage within an average of 9 months. Aortic insufficiency associated with dehiscence of the prosthetic valve developed in 11 of 12 surgical cases (92 percent) with a mechanical valve and 2 of 5 surgical cases (40 percent) with tissue valves. Thirteen of 15 surgeries (87 percent) which were not given postoperative immunosuppressive therapy developed complications, while none of 2 surgeries that used postoperative immunosuppressive therapy with prednisolone (1 mg/kg/day) and azathioprine (100 mg/day) had these complications. CONCLUSION: The rates of prosthetic valve detachment in BD involving aortic valve were higher than those of other diseases. Aortic valve involvement was also one of the poor prognostic factors in BD. Intensive postoperative immunosuppressive therapy and surgical methods may be important factors for postoperative results.

Rosai-Dorfman disease (RDD) is a rare and benign self-limited disorder with pathologic feature of the lymph node sinuses expanded by a proliferation of distinctive histiocytes. The most often involving site is bilateral cervical lymphadenopathy, followed by the skin and soft tissue. Treatment options, including steroid, chemotherapy, radiotherapy and debulking surgery depend on the symptoms or the extent and localization of the lesions. We encountered a very rare case of RDD at the skin lesions, particularly combined with aortic vasculitis, arrhythmia, and valvular heart disease.

OBJECTIVETo evaluate the effect and possibility of surgical ablation of the pulmonary vein orifices under direct vision with transballoon ultrasound ablation catheter for patients with permanent atrial fibrillation and rheumatic valve disease.
METHODS21 consecutive patients with rheumatic valve disease and permanent atrial fibrillation undergoing mitral valve replacement surgery were enrolled for this study from December 2002 to September 2003. All the cases were divided into 2 groups by whether or not receiving an additive pulmonary vein ablation procedure. The test group [6 male, 5 female, aged (51.55 +/- 7.83) years, atrial fibrillation duration (5.50 +/- 5.40) years, left atrial diameter (7.27 +/- 1.39) cm, LVEF (53.95 +/- 4.54)% and NYHA class II - IV] undertook a surgical isolation of the pulmonary vein orifices by using a transballoon ultrasound ablation catheter addition to routine mitral valve replacement. The control group [3 male, 7 female, aged (53.30 +/- 7.86) years, atrial fibrillation duration (4.50 +/- 3.47) years, left atrial diameter (6.74 +/- 0.62) cm, LVEF (56.91 +/- 3.78)% and NYHA class II - IV] received the valve replacement surgery alone.
RESULTSThere were not any complications in both groups. With an electrical cardioversion 3 months after the surgery, 73% patients in the ultrasound ablation group were free from AF over 1 year while only 10% patients in control group (P=0.003). During an average follow-up duration of (45.92 +/- 4.61) months, 63.6% were in sinus rhythm in ultrasound ablation group while none in the control group. Left atrial volume decreased significantly at 1 year after surgery compared to that at 3 months after surgery in the test group [(97.83 +/- 32.39) cm(3) vs. (150.78 +/- 52.32) cm(3), P<0.05], and the end systolic diameter (LAESD) and end diastolic diameter (LAEDD) also decreased [(4.12 +/- 0.39) cm vs. (5.09 +/- 0.98) cm, P<0.05, respectively], while there were no apparently changes in the control group.
CONCLUSIONSAblation of the orifices of the pulmonary veins under direct vision with transballoon ultrasound ablation catheter during mitral valve surgery seems effective to maintain sinus rhythm after electrical cardioversion and could be performed safely. The function of left atrial and cardiac output improved during long term follow-up of 46 months.

Cream formula has been mostly used to treat deficiency syndrome. Currently,it has been used to recuperate the body,promote health against aging,and prevent and treat chronic disease. In modern medicine,there are only treatment concepts and methods of diseases,but lack of concepts of " deficiency syndrome" and " restoring deficiency". The concepts of " deficiency syndrome" and " restoring deficiency" could effectively supplement and improve the diagnosis and treatment scheme of some modern diseases. Refractory heart failure,dilated cardiomyopathy,ischemic cardiomyopathy,and valvular heart disease belong to the traditional category of " consumptive disease". The cream formula with the efficacy of restoring deficiency can not only alleviate symptoms and improve the quality of life,but also improve the structure and function of the heart,reduce the dosage of diuretics and the number of hospitalizations,and achieve the purpose of secondary prevention in the treatment of severe heart failure,dilated cardiomyopathy,ischemic cardiomyopathy and valvular heart disease. The cream formula for treating chronic heart failure include Shenqi Pills,Zhenwu Decoction,Yougui Pills,Wuling Powder,Linggui Zhugan Decoction,Danggui Shaoyao Powder,Lizhong Decoction,Buzhong Yiqi Decoction,Guipi Decoction,Yupingfeng Powder,Guizhi Decoction. Long-term administration of cream formula could not only resist aging,but also play an irreplaceable role in the secondary prevention of acute and critical diseases.
