Effect of Levosimendan on the prognosis in severe coronary disease patients undergoing coronary artery bypass grafting / 中华老年医学杂志

Objective To evaluate the effect of Levosimendan on the prognosis in patients with severe coronary heart disease after operation.Methods A total of 485 severe coronary disease patients undergoing coronary artery bypass grafting from Teda International Cardiovascular Hospital and the Cardiac Surgery Department of the First Affiliated Hospital of China Medical University from May 2014 to June 2016 were enrolled.Of them,45 cases receiving Levosimendan postoperatively were assigned to the Levosimendan group,and according to propensity score matching,another 45 cases were selected as the control group in this study.Clinical data before treatment had no difference between the groups (P ＞ 0.1).Postoperative prognosis was compared between the two groups.Results There were significant differences in heart rate,mean arterial pressure,central venous pressure,cardiac output and other hemodynamic parameters between the two groups 48h after operation.The heart ultrasound results showed that the left ventricular ejection fraction(IVEF) was increased [(0.53±0.12) ％vs.(0.46±0.09)％,t =2.594,P=0.002],the postoperative ventilation time was reduced [(46.8±11.3) h vs.(58.5±16.3) h,t=-2.031,P=0.045]and the onset of bowel sounds became early [(16.5±5.9) h vs.(18.7±10.1) h,t =1.592,P=0.039]in the levosimendan group than in the control group 48h after operation.The incidences of new-onset acute kidney injury(20 ％ and 40 ％,x2 =6.702,P =0.018),new-onset postoperative atrial fibrillation (15.6％ and 44.4％,x2 =6.156,P =0.023) and perioperative myocardial infarction(11.1 ％ and 33.3％,x2 =6.429,P =0.021) had significant differences between the two groups(P＜0.05),but there was no difference in ICU retention time,1-month mortality after operation,malignant arrhythmia incidence and auxiliary equipment use (P ＞ 0.05).Conclusions Levosimendan can improve the early prognosis of severe coronary disease patients undergoing coronary artery bypass grafting and reduce the occurrence of postoperative organ dysfunction.

Application of vacuum-assisted venous drainage technology in minimally invasive cardiac surgery / 中国医疗器械杂志

<p><b>OBJECTIVE</b>To summarize the method and experience of cardiopulmonary bypass (CPB) with vacuum-assisted venous drainage technology (VAVD) in the minimally invasive cardiac surgery (MICS).</p><p><b>METHODS</b>35 cases of patients undergoing MICS were achieved femoral arterial cannula and femoral venous cannula. During the course of the CPB, we used the VAVD technology. At the same time, we selected 35 cases as control group.The time of the CPB, mechanical ventilation and ICU, and the amount of the urine, blood products, and chest drainage were recorded.</p><p><b>RESULTS</b>The time of mechanical ventilation and ICU staying, the volume of the blood products and the volume drainage within 48 h postoperatively in the MICS group were significantly shorter and less than that in control group (P < 0.05).</p><p><b>CONCLUSION</b>The use of VAVD in the MICS can increase the vena cava drainage effectively, and ensure the surgery safe and successful.</p>

The diagnosis and surgical treatment for primary cardiac malignant tumors / 中华胸心血管外科杂志

Objective To investigate the diagnosis and therapy of primary maligmant tumors of the heart. Methods Clinical data of 21 patients with malignant cardiac tumors admitted to our department from June 1980 to May 2008 was analyzed and the references were reviewed. Results All patients received operations. Pathological classification of the tumors was made by histological examinations. Radical resections for 10 eases and partial resections for 5 eases were performed. The other 6 patients received only thoracotomy and cardiac exploration. Three eases were lost during follow up. Three survivors received radical resections are still alive now 2-15 months after the surgery, while all the other patients died within 4 years after the operation due to malignant tumor recurrence and (or) metastasis. Conclusion Echocardiography, CT, 3D-CT, MRI, coronary CT and angiocardiography are helpful for the diagnosis of the malignant cardiac tumors and the selection of operations. Histological examination is necessary for the final diagnosis. Early diagnosis, radical resection and post-operative radiotherapy and chemo therapy may provide a better result.
