Objective To investigate the effect of applying intraoperative epicardial echocardiography (IEE) on preoperative monitoring and evaluating the clinical result of cardiac surgery.
Methods We retrospectively analyzed the clinical data of 248 patients treated in the Affiliated 105 Hospital of People’s Liberation Army and the First Affiliated Hospital of Anhui Medical University from June 2008 to May 2015. There were 108 males and 140 females. The age ranged from 7 months to 71 years. There were 113 patients diagnosed with the congenital heart disease (CHD) at the mean age of 11.89±14.74 years. There were 135 patients diagnosed with valvular heart disease at the mean age of 47.20±14.57 years. All patients underwent IEE during operation.
Results In 113 patients with CHD, we found new deformities and corrected preoperative diagnosis before cardiopulmonary bypass (CPB) and we identified surgical complications after CPB by IEE. Other deformities and left atrial thrombus were found in 135 patients with valvular heart disease by IEE before CPB. After CPB, paravalvular leak and mitral regurgitation were found, therefore we took action immediately.
Conclusions IEE can improve the preoperative diagnosis and reduce perioperative complications, which has value of application during cardiac surgery.
Objective To evaluate the effectiveness and prospect of nontransplantation surgical cardiac remodeling for endstage cardiac valve disease by performing the remodeling operation (including anatomical and functional remodeling) after strict perioperative adjustment for endstage cardiac valve disease. Methods We retrospectively analyzed the clinical data of 31 patients, including 14 males and 17 females, with endstage cardiac valve disease who were treated with surgical cardiac remodeling operation from December 2005 to July 2009 in the 2nd Hospital of Anhui Medical University . Their age ranged from 27 to 74 years with an average age of 40.4 years. Continuous renal replacement therapy (CRRT) was carried out 3 days before surgery in all patients and intraaortic balloon pumping (IABP) was performed 1-3 days before operation in 9 patients. Among the patients, there were 13 patients of mitral valve replacement (MVR), 7 patients of aortic valve replacement (AVR), 4 patients of tricuspid valve replacement (TVR), and 7 patients of double valve replacement (DVR). At the same time, all patients underwent ventricular or atrial volume reduction operation, including 19 patients of left atrial partial excision or plication, 7 patients of partial left ventricular excision, 5 patients of left atrial and left ventricular volume reduction operation, 21 patients of partial right atrial excision, and 3 patients of partial right ventricular excision. Besides, there were 5 patients of De Vega plasty, 14 patients of annuloplasty and3 patients of coronary artery bypass grafting (CABG). The echocardiogram was used to observe the change of heart function, atrium and ventricular in patients on postoperative and follow -up period. Results After surgery, one patient died of low cardiac output syndrome, and one other patient gave -up because of incision and mediastinum infection after reoperation for hemorrhage. Twentynine patients were followed -up for 3 to 12 months with 1 case lost. During the follow- -up, 3 patients died, of whom 2 died of deterioration of heart function and 1 died of sudden stroke. In the 12th month during the follow -up, heart function of all other 25 patients showed obvious improvements with 12 classⅠ, 7 classⅡ, 3 classⅢ and 3 classⅣ heart function according to NYHA classification. At the end of the follow -up, ejection fraction (5400%±800% vs. 2500%±300%) and cardiac index [3.30±0.50 L/(min·m2) vs. 1.10±0.30 L/(min·m2)] were significantly higher than those before operation (P<0.05), whereas left ventricular end diastolic diameter (5200±1000 mm vs. 9500±1200 mm) and left atrial diameter (3900±800 mm vs. 7000±1200 mm) both decreased significantly than those before operation (P<0.05). Conclusion Cardiac remodeling operation for endstage cardiac valve disease after active adjustment and preparation can achieve similar results to operation for severe valve diseases, providing a new choice for endstage heart disease.
目的 總結風濕性心瓣膜病三尖瓣關閉不全( TI)手術治療的臨床經驗,以提高對該類患者的治療效果。 方法 1999年1月至2009年1月安徽醫科大學第一附屬醫院對167例風濕性心瓣膜病累及三尖瓣患者行手術治療,其中男76例,女91例;年齡16.0~75.0歲(40.7±10.4歲);病程2.0~35.0年(13.2±3.8年)。112例輕度至中度三尖瓣反流采用改良或節段性De Vega成形術,40例中度或中度至重度三尖瓣反流采用Kay或改良Kay成形術;12例因瓣環擴張明顯、反流量大,行人工瓣環成形術,三尖瓣置換術3例。術后觀察三尖瓣反流情況,隨訪超聲心動圖結果。 結果 術后早期死亡6例,其中死于心搏驟停1例,腎功能衰竭2例,腦血管意外1例,心室破裂1例,縱隔感染致敗血癥1例。1例術中因低心排血量使用主動脈內球囊反搏(IABP)治療,治愈出院。隨訪159例,隨訪時間3~123個月,失訪2例。隨訪期間心功能分級(NYHA)Ⅰ級115例,Ⅱ級32例,Ⅲ級12例。三尖瓣輕度反流15例,中度反流5例,重度反流2例。隨訪期間三尖瓣隔瓣與前瓣瓣環間直徑(2.1±0.3 cm vs. 3.5±0.4 cm, P=0.000)、三尖瓣瞬時反流量(1.8±0.6 ml vs. 7.8±3.5 ml, P=0.001)和右心房容積(54.2±18.4 ml vs. 67.8±22.5 ml, P=0.012)較術前明顯減少或縮小; 射血分數(56.1%±7.2% vs. 54.3%±6.5%,P=0.313)較術前有所提高。 結論 心臟瓣膜病中TI需引起重視,應選擇適宜的方法積極治療。
