Clinical evaluation of percutaneous atrial septal defect closer guided by transthoracic echocardiography and/or transesophageal echocardiography / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the safety and efficacy of percutaneous closure of the single secundum atrial septal defects (ASD) guided by transthoracic echocardiography (TTE) and/or transesophageal echocardiography (TEE).
@*METHODS@#From January, 2014 to December, 2014, thirty-two patients with single secundum ASD from Department of Cardiovascular Surgery, Union Hospital, Fujian Medical University, were treated with percutaneous closure of ASD guided by TTE or TEE.
@*RESULTS@#Thirty-two patients underwent ASD closure successfully, except one patient showed trivial residual shunts, which disappeared one month later. The remaining 31 patients were subjected to TTE. At once or at the 1st or 3rd month after the procedure, no ASD migration or residual shunts were observed.
@*CONCLUSION@#Percutaneous closure of ASD guided by TTE or TEE is a safe and effective surgery method with minimal invasion and can avoid the chest incision and radioscopy.

Ebselen can attenuate the ischemia-reperfusion injury of the rat lungs from non-heart -beating donors / 中华器官移植杂志

Objective To evaluate the effect of Ebselen on the ischemia-reperfusion injury (IRI) in rat lungs from non-heart-beating donors (NHBD).Methods Forty Sprague-Dawley rats were paired randomly divided into two groups:group Ⅰ,NHBD with 30 min of warm ischemia time (WIT); group Ⅱ,NHBD with 30 min of WIT and administration of Ebselen.The donor lungs remained ventilated at the room temperature for 30 min after asystolia and then flushed with LPD solution.The recipient rats underwent left lung transplantation.The recipients of group Ⅱ were administered with Ebselen (500 mg/kg body weight) one h before transplantation.Results All the recipients survived during the observation period.In the group Ⅱ,the MDA of the pulmonary tissue was 0.631 ± 0.23 nrmol/mg protein,and the polymorphonuclear neutrophils and the total protein of the bronchoalveolar lavage fluid were (78.4 ± 35.2) × 107/L and (0.41 ± 0.12) mg/ml respectively.The MPO was (25.09 ± 1.19) ％ and W/D was 0.359 ± 0.017.There was significant difference between group Ⅱ and group Ⅰ (all P＜ 0.05).Conclusion The administration of ebselen is an effective treatment to attenuate the acute injury resulted from the ischermia-reperfusion in the rat lungs from non-heart-beating donors.

The analysis of the death cases in orthotopic heart transplantation: 14 cases report / 中华器官移植杂志

Objective To explore the related causes and management of the death cases (following) orthotopic heart transplantation (OHT). Methods The data of the death cases (14 cases) were studied retrospectively.Results Fourteen cases died among the total 54 cases of OHT from Aug. 1995 to Dec. 2004 in our hospital. Eight cases died within 1 month and 1 case subject to combined heart-kidney transplantation died on the 38th day, and the other 5 cases died during the period from 17 weeks to 4 years. The death cases died of acute right ventricular failure (4 cases), lung infection (5 cases, including 3 cases associated with fungus infection), acute rejection (4 cases), acute renal failure (4 cases), arrhythmia (4 cases), adult respiratory distress syndrome (2 cases) and diabetes (2 (cases)). The death of 8 cases was related with several causes.Conclusion Various causes should be (responsible) for the results. In order to decrease the mortality rate, the recipients should be selected with low pulmonary vascular resistance and less preoperative complications. It is very important to discover and manage complications in time perioperatively.

Prevention and treatment of right graft-heart dysfunction at early stage post transplantation-report of 28 cases / 中华器官移植杂志

25?cm H 2O). Three of 6 d ead cases died of right heart failure after transplantation, whose PVR were more than 5 woods preoperatively. Twenty-two patients survived for 18 months with g ood quality of life.ConclusionAccurate selection for donor and recipient, suitable surgical procedure, excelle nt myocardial preservation, effective protection of recipient's renal function, early prevention and management of right graft-heart dysfunction can significa ntly decline incidence of right heart failure at postoperative early stage.

Long-term outcomes of orthotopic heart transplantation: a clinical analysis of 40 cases / 中华胸心血管外科杂志

Objective To explore the experience of long-term outcomes of orthotopic heart transplantation. Methods From Aug. 1995 to Dec. 2004, 40 patients with end-stage dilatation cardiomyopathy, 36 males and 4 females, aged 13～60 years underwent orthotopic heart transplantation (OHT) , 39 standard styles and 1 total style. Results 40 cases were all successful treated. The survival time is from 8 to 112 months with heart function of 0-I degree. All cases are in good quality of live and enjoy normal entertainments and work. Pulmonary infection and cardiac arrhythmia are the most common complications but they did not degrade the result after proper treatments. Conclusion Heart transplantation is an effective treatment for patients with end-stage heart diseases. Appropriate selections of recipients with low pulmonary vascular resistance, satisfactory myocardial preservation are the key points to success. The precautions and prompt treatments to the postoperative complications are guarantee for the ultimate results of heart transplantations.
