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.

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.

OBJECTIVETo summarize the clinical features, pathology and surgical treatment experiences in the patients with aortic paravalvular abscess by infective endocarditis.
METHODSThe study consisted of a retrospective analysis of 29 cases with aortic paravalvular abscess by infective endocarditis underwent surgical treatment between January 2001 and June 2013. Among the 29 patients, 22 were male and 7 were female, and the mean age was (37 ± 16) years (range from 11 to 63 years). The primary cardiac disease was congenital aortic valve malformation in 16 patients. There were 15 patients with a history of severe heart failure. Of 29 cases, 8 abscess cavities, 13 pseudoaneurysms and 6 fistulas were found, and complete aortoventricular discontinuity was present in 5 patients with serious infections. Of them, the abscess was above the annulus in 14 patients and below the annulus in 10 patients, and simultaneously involved the annulus above and below in 5 patients. 19 patients were culture positive either positive preoperative blood cultures or positive cultures of surgical specimens, including 9 patients with Staphylococcus infection. The paravalvular defect was repaired by patch in 19 cases, and by local closure in 10 cases. The valvular annulus was reconstructed simultaneously in 16 patients. Aortic valve replacement was performed in 26 patients, and Bentall procedure in 2 patients, including 23 with prosthetic mechanical valve and 5 with biological valve.
RESULTSOf the total 29 patients, 28 patients were recovered, and 1 patient was died of sepsis. During 3 months to 13 years postoperative follow-up (average 4.5 years), one was died of non-cardiac cause, and no patient had recurrent endocarditis and paravalvular leakage.
CONCLUSIONSAortic paravalvular abscess by infective endocarditis is not uncommon, prone to heart failure. According to the different pathological manifestations, the appropriate surgical approach and strategy can achieve satisfactory outcomes.

OBJECTIVETo evaluate the effect of reduction aortoplasty for dilatation of the ascending aorta in patients with aortic valve disease.
METHODSBetween February 1998 and May 2004, 23 patients with aortic valve disease and dilatation of the ascending aorta underwent reduction aortoplasty in combination with aortic valve replacement. The diameter of the ascending aorta was measured before and early after surgery and then later between 4 and 78 months [mean (36 +/- 25) months] postoperatively using echocardiography.
RESULTSThe reduction aortoplasty decreased the diameter of the aorta from (4.8 +/- 0.5) cm preoperatively to (3.6 +/- 0.4) cm early after surgery (P < 0.01). During follow-up, the diameter of aorta increased from (3.6 +/- 0.4) cm early after surgery to (3.7 +/- 0.4) cm after a mean follow-up of (36 +/- 25) months (P < 0.05).
CONCLUSIONReduction aortoplasty shows good mid-term results in patients with aortic valve disease and dilatation of the ascending aorta. Long-term results need to be followed up.

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.

OBJECTIVETo investigate the result of surgical treatment of active infective endocarditis in patients with recent cerebrovascular events, and to evaluate the optimal indication and timing of surgical intervention.
METHODSThe clinical data of 26 patients with cerebrovascular complications before surgery Between December 2007 and December 2013 were analyzed retrospectively. There were 17 male and 9 female patients, aged (42±14) years. Types of disease included single aortic valvular disease (n=8), single mitral valvular disease (n=12), multiple valvular disease (n=5), and aortic valvular disease with ventricular septal defect (n=1). Type of cerebrovascular complication included cerebral infarction (n=25) and cerebral hemorrhage (n=1). Thirty-one valves were involved in 26 patients, mechanical prosthetic valve replacement (n=25), bioprosthetic valve replacement (n=4), and mitral valve repair (n=2).
RESULTSThe interval between onset of cerebrovascular event and surgical intervention was less than 14 days (n=3), 14 to 21 days (n=13), over 21 days (n=10), and the mean was (20±4) days. There were 33 vegetations found intraoperatively. The mean size of vegetations was (10±4) mm and 19 were found in mitral valve. Two patients died in hospital. One case relapsed after 1 year and underwent reoperation for prosthetic valve endocarditis. The remaining patients recovered with cardiac function of New York Heart Association class I to II after the period of 3 months to 5 years follow-up.
CONCLUSIONSAppropriate surgery may effectively improve the outcome of IE patients with cerebrovascular complications. The surgical indications and risks of further neurologic deterioration after cardiac surgery should be assessed comprehensively before surgical intervention.

OBJECTIVETo analyze the early and long-term results after mitral-aortic valve replacement for rheumatic valvular disease and the determinant factors involved and subsequent therapies.
METHODS1 154 patients receiving combined mitral-aortic valve replacement for rheumatic valvular disease from May 1981 to May 2001 were reviewed. The mean age of the patients was 41.48 +/- 10.00 years. Concomitant valve plasty was performed for associated tricuspid organic or significant functional lesions. Lateral tilting disc or bileaflet valve prostheses were used for replacement. New York Heart Association functional status showed Class III or IV in 91.77% of the patients. Moderate to severe pulmonary hypertension occurred in 29.38% of the patients. The duration of follow-up varied from 8 months to 20 years.
RESULTSThe hospital mortality was decreased from 6.50% to 4.45%. The 5-, 10- and l5-year survival rates were 89.46% +/- 1.35%, 86.50% +/- l.91% and 67.86% +/- 6.16%, respectively. The 5-, 10- and l5-year thromboembolic event free rates were 97.80% +/- 0.74%, 88.31% +/- 2.20% and 94.08% +/- 2.29%, respectively. the 5-, 10- and l5-year anticoagulant related bleeding free rates were 94.80% +/- 1.09%, 89.32% +/- 2.10% and 83.12% +/- 3.57% respectively. Cardiac functional status returned to Class II in 98% patients and to Class III in 2% during follow-up.
CONCLUSIONSBoth left and right ventricular functions may be impaired as a result of rheumatic valvular disease. Tricuspid valve should be explored during surgery and any significant tricuspid annular enlargement and regurgitation showed be corrected in concomitance. Long-acting penicillin regimen is needed for 3 - 5 years for the prevention of rheumatic fever relapse. A low intensity anticoagulant regimen after valve replacement with prothrombin time targeting at 1.5 - 2.0 times is advisable in lessening anticoagulant related bleeding yet optimizing sufficient prevention against thromboembolic complications.

Triple valve surgery is usually complex and carries a reported operative mortality of 13% and 10-yr survival of 61%. We examined surgical results based on our hospital's experience. A total of 160 consecutive patients underwent triple valve surgery from 1990 to 2006. The most common aortic and mitral valve disease was rheumatic disease (82%). The most common tricuspid valve disease was functional regurgitation (80%). Seventy-four percent of the patients were in New York Heart Association (NYHA) class III and IV. Univariate and multivariable analyses were performed to identify predictors of early and late survival. Operative mortality was 6.9% (n=11). Univariate factors associated with mortality included old age, preoperative renal failure, postoperative renal failure, pulmonary complications, and stroke. Of them, postoperative renal failure and stroke were associated with mortality on multivariable analysis. Otherwise, neither tricuspid valve replacement nor reoperation were statistically associated with late mortality. Survival at 5 and 10 yr was 87% and 84%, respectively. Ninety-two percent of the patients were in NYHA class I and II at their most recent follow-up. Ten-year freedom from prosthetic valve endocarditis was 97%; from anticoagulation-related hemorrhage, 82%; from thromboembolism, 89%; and from reoperation, 84%. Postoperative renal failure and stroke were significantly related with operative mortality. Triple valve surgery, regardless of reoperation and tricuspid valve replacement, results in acceptable long-term survival.

OBJECTIVETo introduce the experience in coronary artery bypass grafting (CABG) combined with concomitant valve operation.
METHODSFrom 1998 to 2002, forty-five patients (38 men and 7 women) with coronary artery lesion and valve diseases underwent myocardial revascularization combined with concomitant valve operation. The mean age of the patients was 59 years (42 to 75 years). Heart function was Class II (NYHA) in 7 patients, Class III in 30, Class IV in 8. The value of ejection fraction was 0.32 to 0.50. Thirty patients had mitral valve lesion, 7 aortic lesion, and 8 both lesions. Seventeen patients had single-vessel diseases, 20 double-vessel diseases, 8 triple -vessel diseases, and 8 left main artery lesion. After cardiac arrest by cold blood cardioplegia under moderate cardiopulmonary bypass (CPB), distal anastomosis of the saphenous vein (SV) to the target vessels were firstly performed and followed by valve replacement (32 patients) or plasty (2). The left internal mammary artery (LIMA) was grafted to the left anterior descending artery (LAD) before aortic unclamping. Proximal anastomosis of the SV to the aorta was finally finished on beating heart. The mean bypass time was 173.5 min and the mean duration of aortic cross-clamping time was 112.6 min.
RESULTSNo mortality occurred during hospitalization and all patients were discharged 9.2 days after operation. Cardiac function of all patients was improved to Class I-II and no patient died during follow-up.
CONCLUSIONSCABG combined with valve surgery can be safely performed with good results.

OBJECTIVETo study the changes in pathogenic causes and the prognosis of aortic valve replacement (AVR).
METHODSThe clinical data of 1026 patients undergoing AVR from December 1980 to December 2006 were analyzed retrospectively. The mortality, morbidity, changes in pathogenic causes and risk factors were analyzed.
RESULTSThe postoperative mortality and complication morbidity were 4.3% and 10.6% respectively within 30 days followed operation. Main causes of operative death were heart failure, multi organ failure and endocarditis. The major risk factors for operative death were left ventricle ejection fraction less than 0.4, endocarditis, valve regurgitation and emergency operation before AVR. Late mortality was 0.54% patient-year (3.4%), most of whom died of heart failure, endocarditis and arrhythmias. Patients underwent reoperation 0.22% patient-year (1.4%), with the causes of endocarditis and perivalvular fistula.
CONCLUSIONSMorbidity of rheumatic damage in aortic valve has decreased, while valve degeneration has increased gradually in the recent years. Avoiding prosthesis-patient mismatch, good postoperatively guide and prevention of endocarditis can improve the prognosis of AVR.
