ObjectiveTo study the relationship between the timing of surgery and one-year outcome in patients with infective endocarditis.
MethodsWe retrospectively analyzed the clinical data of 97 patients suffered from leftside native valve infective endocarditis with neoplasm, admitted in Shanghai First People's Hospital between January 2000 and December 2011. There were 65 males and 32 females with mean age of 55.2±16.3 years (ranged 29 to 75 years). They were divided into two groups according to whether the surgery was performed within a week after diagnosis. The in-hospital mortality and one-year mortality, embolism and re-infection were calculated and compared between the two groups.
ResultsThere was no significant difference in the in-hospital mortality between the early surgery group and the conventional surgery group (1.9% versus 6.7%, P=0.241). While there was a significant difference in the rate of inhospital embolism related complications (1.9% versus 13.3%, P=0.030) between the two groups. There was no significant difference in one-year mortality between the two groups (1.9% versus 8.9%, P=0.122). The incidence rate of embolism related complication was 5.8% in the early surgery group and 20.0% in the conventional surgery group with a statistical difference (P=0.034). There was one patient with recurrent cerebral infarction among the 11 patients of cerebral infarction in the early surgery group,while 6 recurrent patients in the 9 patients with cerebral infarction in the conventional surgery group (9.1% versus 66.7%, P<0.005).
ConclusionsEarly surgery in patients with left-side native valve infective endocarditis can't reduce the in-hospital mortality and one-year mortality but does decrease embolic events significantly. Early surgery is feasible in the patients with cerebral infarction.
Abstract: Objective To summarize the experience of combined coronary artery bypass grafting(CABG) and valve replacement. Methods From May 1997 to March 2006, the results of 80 consecutive patients undergone valve replacement (MVR) and CABG were analyzed. CABG were performed withtotal grafts in 159 grafts (mean 1.99 grafts), with mitral valve replacement (MVR) in 49 patients, with aortic valve replacement (AVR) in 18 patients, with MVR+AVR in 13 patients(mechanical valve replacement in 68 and biological valve replacement in 12). Results The hospital time after operation was 19.2±13.4d. The hospital mortality rate was 12.5% (10/80). The primary cause of death included low cardiac output yndrome, acute renal failure, nervous system complications ,ventricular fibrillation and cardiac arrest. Multivariate testing of preoperative and operative description identified that preoperative myocardial infarction, worse cardiac function, radiographic cardiac enlargement and low ejection fraction were associated with an increase of hospital mortality (P＜0.05). There were postoperative complications including bleeding, severe ventricular arrhythmia, nervous system complications and incision infection. Followup of 58 patients (82.86%, range 6 to 60 months) showed the symptoms of angina pectoris and heart failure were significantly relieved. There were 2 longterm deaths (cerebral infarction and lung infection). Conclusion Combined CABG and valve replacement is an effective way for treatment of coronary artery and valvular heart disease. Improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for success operation.
Objective To summarize the essential of perioperative therapy and improve the prognosis of coronary artery bypass grafting （CABG） and transmyocardial laser revascularization （TMLR） through analyzing 1405 patients with coronary atherosclerotic heart disease. Methods From May 1997 to January 2006, 1 405 patients were treated in our hospital. On-pump CABG were performed in 825 patients, single CABG were performed in 666 patients, CABG with cardiac valvular operation in 98 patients, CABG with cardiac ventricular aneurysm resection in 55 patients, CABG with ventricular septal defect repairment in 2 patients; CABG with left atrium gelatinous tumor resection in 2 patients, CABG with ascending aorta repairment in 1 patient, and mediastinal septum tumor resection in 1 patient. Off-pump coronary artery bypass grafting （OPCAB） were performed in 500 patients; single TMLR were performed in 30 patients, CABG＋TMLR were performed in 50 patients. Results The number of bridge vessel was 2.9±1.0. Forty-two patients（3.0%） died of bleeding, myocardial infarction, low cardiac output syndrome, renal failure, multiple organ failure（MOF） and so on. Various complications were occurred in 70 patients（5.0%）, including bleeding, low cardiac output syndrome, myocardial infarction, renal failure and so on. All of them were recovered after treatment. There were 1 177 patients of angina in grade Ⅲ-Ⅳ （CCS） before operation, 1 154 of them （98.0%） changed in grade 0-Ⅰ （CCS） postoperatively. There were 857 patients （62.9%） in follow-up for 8.3±2.9 months postoperatively. There was no angina in 788 patients（91.9%） 6 months after surgery. The ultrasonic graphic showed that left ventricular ejection fraction was 0.66±0.10 and raised 7.9% than that before operation. The quality of life was better than before. Conclusion CABG has become the most potent routine operation in the therapy of coronary artery disease. It can extend the applications of CABG and improve the operative prognosis, if the indications are correctly mastered and the perioperative management are enhanced.
Objective
To compare the effect of monopolar and bipolar radiofrequency ablation in patients with atrial fibrillation and concomitant rheumatic heart disease.
Methods
The clinical data of 261 patients who underwent valve replacement and radiofrequency Maze Ⅲ procedure in Shanghai First People's Hospital from 2010 to 2015 were retrospectively analyzed. According to the radiofrequency ablation system, patients were assigned to a monopolar radiofrequency ablation group (n=209, 129 males, 80 females, aged 59.6±9.7 years) and a bipolar radiofrequency ablation group (n=52, 36 males, 16 females, aged 58.6±11.2 years). After procedures, clinical factors such as patients' basic information, perioperative complication and mortality, the elimination rate of atrial fibrillation were measured.
Results
There was no statistic difference in perioperative morbidity and mortality between two groups. The ablation time of the monopolar radiofrequency ablation group was longer than that of the bipolar group (29.7±3.3 minvs. 22.3±7.8 min,P=0.035). Postoperative diameter of left atrium was reduced in both groups. Compared with the monopolar radiofrequency ablation group, bipolar group had a better elimination rate of atrial fibrillation at three months and one year follow-up (82.0%vs. 66.3%,P=0.037; 80.0%vs. 59.6%,P=0.008).
Conclusion
Valve replacement combined with radiofrequency Maze Ⅲ procedure is safe and efficient. Compared with monopolar radiofrequency ablation, bipolar radiofrequency ablation has advantage on elimination rate of atrial fibrillation, ablation time and cardiopulmonary bypass time.
