From Feb. 1985 to Aug. 1996, 450 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. In 450 cases of open heart surgery, 222 cases(49.3%) were congenital heart diseases and 228 cases(50.7%) were acquired heart diseases. In 222 cases of congenital heart diseases, there were 201 cases of acyanotic heart disease and 21 cases of cyanotic heart diseases. Among the 228 cases of acquired heart diseases, most cases were valvular heart diseases in which 206 valves were implanted. There were 32 cases of ischemic heart disease and the average graft anastomoses were 2.37 sites per operation. The operative mortality of congenital and acquired disease was 9.0% and 10.1% respectively and then overall mortality rate was 9.6%.

BACKGROUNDAortic valve replacement (AVR) is a safe and effective method in the treatment of aortic valve diseases. This study aimed to increase the understanding on re-treatment of aortic diseases after aortic valve surgery through a retrospective analysis of 47 related cases.
METHODSForty-seven patients (38 males and 9 females) with previous aortic valve surgery have received reoperation on aorta from January 2003 to June 2012, and the mean interval time of re-intervention to aortic disease was 6 years ((6.0 ± 3.8) years). The secondary aortic surgery included aortic root replacement (14 cases), ascending aorta replacement (10 cases), aortic root/ascending aorta plus total arch replacement with stented elephant trunk implantation (21 cases), and total thoracoabdominal aorta replacement (2 cases). All these patients have received outpatient re-exams or follow-up by phone calls.
RESULTSAfter the initial aortic valve replacement, patients suffered from aortic dissection (25 cases, 53%), ascending aortic aneurysm (12 cases, 26%) or aortic root aneurysm (10 cases, 21%). Diameter in ascending aorta increased (5.2 ± 7.1) mm per year and aortic sinus (3.3 ± 3.1) mm per year. The annual growth value of diameter in ascending aorta was higher in patients with rheumatic heart disease than that in Marfan syndrome (P < 0.05). All 47 patients have received reoperation on aorta. One patient died in operating room because aortic dissection seriously involved right coronary artery. Seven patients had renal insufficiency after operation; neurological complications occurred in 14 patients including 7 patients with stroke and the others with transient brain dysfunction. All patients were followed up, the mean survival time was (97.25 ± 17.63) months, 95% confidence interval was 55.24-73.33 months. Eight cases were died during follow-up and five-year survival rate was 83%.
CONCLUSIONTo reduce the aortic adverse events after first aortic valve surgery, it is necessary to actively treat and strictly follow-up patients with previous aortic operation especially patients with Marfan syndrome and rheumatic heart disease.

OBJECTIVETo define the determinants of perioperative death and complications after cardiac valve replacement in 702 patients.
METHODSClinical data of the patients after cardiac valve replacement were analyzed retrospectively.
RESULTSPerioperative mortality and morbidity correlated significantly with some of the perioperative variables, such as higher NYHA functional class (III or IV), large left ventricular end-diastolic diameter (>/= 70 mm), C/T >/= 0.70, prolonged aortic cross-clamping time and cardiopulmonary bypass time, unsatisfactory myocardial protection.
CONCLUSIONSPerioperative mortality and morbidity correlate significantly with some of perioperative variables, such as higher NYHA functional class, unsatisfactory myocardial protection, inappropriate surgical procedure, improper therapy of some complications after cardiac valve replacement. To avoid the occurrence of these independent predictors or to correct them timely might effectively decrease the perioperative mortality and morbidity after cardiac valve replacement.

BACKGROUNDReconstructive surgery is the primary goal in pediatric patients with valve disease. However, in cases with irreparable valve lesions, valve replacement is the only option. This study aimed to retrospectively analyze the clinical experience of heart valve prosthesis replacement in children.
METHODSBetween January 1990 and July 2009, 35 pediatric patients (16 boys, 19 girls) underwent mechanical valve replacement in Shandong University Qilu Hospital. The ages ranged from 2.5 to 14 years (mean, (8.8 ± 3.8) years) and body weight varied from 11 to 37 kg (mean, (22.1 ± 5.2) kg). Mechanical valve replacement was performed because of congenital heart disease in 23 patients, rheumatic disease in ten patients and infective endocarditis in two patients. St. Jude bileaflet mechanical valves were implanted in all the 35 patients including mitral valve replacement (MVR) in 18, aortic valve replacement (AVR) in 12, tricuspid valve replacement (TVR) in two, AVR and MVR in two and MVR and TVR in one. The size of the prostheses ranged between 19 and 27 mm. All patients received long-term anticoagulation treatment with sodium warfarin, aiming to maintain an international normalized ratio between 1.5 to 2.0. Follow-up was performed in all the patients with a total follow-up of 119.4 patient-years.
RESULTSThe operative mortality was 8.57% (3/35). One patient, who underwent cardiac debridement and AVR, died 2 hours after being admitted to the intensive care unit because of severe low cardiac output syndrome and ventricular fibrillation. Two patients died of cardiogenic shock and renal failure during initial hospitalization after the operation. One patient who received replacement of a tricuspid valve developed complete heart block requiring temporary pacing and recovered sinus rhythm 4 days later. Thirty-two patients survived and their cardiac function was in New York Heart Association (NYHA) class I to class II when discharged. Late events included hemorrhage and endocarditis. Two patients required reoperation. No late deaths occurred during the follow-up.
CONCLUSIONSMechanical valve replacement remains an acceptable treatment option in children when the valve reparation is impossible or unsuccessful. The operative mortality and incidence of any valve-related events such as endocarditis, reoperation, thromboembolism or anticoagulation-related bleeding are acceptable.

BACKGROUND: The purpose of writing this article is to get better clinical results and further clinical improvement based on subject to 110 cases of cardiac surgery which were performed and clinically analyzed. MATERIAL AND METHOD: Since January 1995, the patent ductus arteriosus surgery had started in our hospital. In February 1999, an open heart surgery had started and up to September 2000, total of 110 cases were performed as of double ligation of patent ductus arteriosus(10 cases) and open heart surgery(100 cases). RESULT: Among the patients, Korean-Chines was 74(67.3%) and Han-Chinese was 35(31.8%). Congenital heart disease was 95 cases and acquired valvular heart disease was 15 cases. 83 cases of acyanotic congenital heart disease consisted of ventricular septal defect(VSD) with associated anomaly(45 cases), atrial septal defect(ASD) with associated anomaly(20 cases), patent ductus arteriosus(PDA) with associated anomaly(11 cases), congenital aortic stenosis(5 cases), double chamber right ventricle(1 case) and Ebstein's anomaly(1 case). Among the 12 cases of cyanotic congenital heart disease, 11 cases of tetralogy of Fallot underwent total correction. Among the 15 cases of acquired valvular heart disease, valvular replacement(7 cases), double valve replacement(3 cases), mitral valve replacement(3 cases) and aortic valve replacement(1 case) were performed. And 8 cases of valvuloplasty were performed by using of commissurotomy, chordal plasty, plasty of papillary muscle, ring type annuloplasty, repair of leaflet. CONCLUSION: On congenital heart disease, short term results of surgery for acyanotic congenital heart disease was good. Among the cyanotic congenital heart disease, tetralogy of Fallot showed a little difference of recovery according to the surgery method so that further follow up observation was needed for long term result. On acquired valvular heart disease, especially. in terms of short term result of valvuloplasty, was relatively good, but further follow up observation was also needed for long term result. There wasn't any operative mortality.

OBJECTIVETo retrospectively review the experience of reoperation after closed mitral commissurotomy, valvuloplasty, perivalvular leakage and dysfunction of bioprosthetic valve in 221 cases.
METHODSTwo hundred and twenty-one patients underwent heart valve reoperation from January 1998 to August 2005. Among them, 8 cases was emergency operation. The reasons of reoperation included 105 cases suffered from mitral valve restenosis after closed mitral commisurotomy, 37 cases suffered from valve lesion after mitral or aortic valvuloplasty, 29 cases suffered from perivalvular leakage after valve replacement. Eighteen cases suffered from bioprosthetic valve decline, 9 cases suffered from dysfunction of machine valve, 7 cases suffered from tricuspid insufficiency of Ebstein, 5 cases suffered from prosthetic valve endocarditis and 11 cases suffered from other valve disease. The re-operations were mitral valve replacement, mitral and aortic valve replacement, aortic valve replacement and tricuspid valve replacement. The interval from first operation to next operation was 1 - 21 years.
RESULTSThe early-stage postoperative mortality was 8.6% (19/221). And the reasons were low cardiac output syndrome, arrhythmia, multiple organ dysfunction failure (MODF) and renal failure. Among these the emergency operative mortality was 3/8. And the mortality was 14.5% (9/62) in class IV of cardiac function (NYHA).
CONCLUSIONSThe risk factors of reoperation about heart valve disease include emergency operation, low preoperative cardiac function, MODF, long time of cardiopulmonary bypass and aortic blocking. Therefore it is emphasized that mastering and treating the risk factors promptly, which could decrease the mortality and incidence of complication.

OBJECTIVETo summarize the experience in tricuspid valve replacement (TVR).
METHODSFrom March 1997 to June 2004, 42 patients underwent isolated or combined TVR. Of the cases, 20 cases had prior cardiac operation (tricuspid valve had been repaired in 8). Indication of TVR: (1) irreparable and/or progressive tricuspid lesions; (2) intolerable tricuspid dysfunction after tricuspid repair. Instead of tricuspid repair, TVR was preferred when one of the following co-existed: moderate to severe increase of pulmonary vascular resistance; residual left heart dysfunction; previously repaired tricuspid. Simultaneous replacement after unsuccessful tricuspid repair had to be done in 14 cases. Valve replacement combinations were isolated TVR in 30 cases, tricuspid and aortic and mitral in 8, tricuspid and mitral in 3, tricuspid and aortic in 1. Fourteen tissue and 28 bi-leaflet mechanical valve prostheses were used in the tricuspid position. Other simultaneous procedures included corrections of congenital anomalies in 10 patients, repair of peri-prosthetic leakage, resection of myxoma and coronary artery bypass grafting in 1 case each.
RESULTSThe operative mortality was 17%, and mortality 31%. Four patients died of low cardiac output. Massive cerebral thromboembolism, renal failure and dyscrasia was the cause of death in 1 case each. Post-operative heart function NYHA classification: 21 cases in I, 10 in II, 1 in III and 1 in IV. Late death occurred in 2 cases.
CONCLUSIONSTVR is preferable for a severely damaged or deformed tricuspid valve if the possibility of successful repairing is small, especially when accompanied pulmonary vascular disease and uncorrected lesions and/or dysfunction of the left heart co-exists.

OBJECTIVETo summarize the clinical characteristics, surgical management and postoperative complications in patients with congenital bicuspid aortic valve (CBAV) over 50 years of age.
METHODSFrom January 2009 to September 2011, 73 CBAV patients aged 51-76 years (mean 61.8∓0.73 years) were treated in our center. Except for 1 patient who underwent Bentall surgery and another having Wheat surgery, all the patients received aortic valve replacement (AVR), including 7 with double (mitral and aortic) valve replacement (DVR), 6 with mitral valvular plasty, 11 with tricuspid valvular plasty, 8 with coronary artery bypass graft implantation, 1 with aortic-left ventricular tunnel repair, 1 with atrial maze ablation, and 1 with left atrial thrombosis removal.
RESULTSTwo patients died after the surgery, with a perioperative mortality rate of 2.7%. The cardiopulmonary bypass time was 78-217 min (mean 131.9 ∓6.0 min) with an aortic blocking time of 56-158 min (mean 88.2 ∓4.8 min) and total postoperative ICU time of 23.0-647.4 h (mean 97.9∓10.5 h). The postoperative complications included low heart output syndrome in 5 cases, bleeding in 4 cases, wound debridement in 4 cases, and hemodialysis due to acute renal failure in 1 case. The left ventricular end diastolic diameter reduced significantly after the surgery (52.6∓1.7 vs 43.2∓1.0, P=0.001). No significant changes were detected in the left ventricular ejection fraction (62.3∓2.5 vs 65.5∓1.3, P=0.257).
CONCLUSIONThorough preoperative examination, preoperative risk factor assessment, timely perioperative interventions, careful evaluation of patients' tolerance of surgery, and prevention of surgical complications are essential to decrease the perioperative mortality in elderly patients with CBAV.
