  • Choice of Conduit Size and Material for Palliative Right Ventricle-to-Pulmonary Artery Shunt

    Objective To assess clinical results of three different conduit materials (Gore-Tex synthetic graft,bovinejugular vein and autologous pericardium)for palliative right ventricle-to-pulmonary artery (RV-PA) shunt,and explore the correlation between suitable conduit size and patients’ body weight and McGoon ratio. Methods We retrospectively analyzed clinical data of 24 patients with congenital heart diseases who underwent palliative RV-PA shunt in Department of Pediatric Cardiovascular Surgery of Fu Wai Cardiovascular Hospital from July 2010 to July 2012. There were 11 males and 13 females with their age ranging from 60 days to 6 years and body weight of 10.22±7.41 kg. There were 22 patients with pulmonary atresia and ventricular septal defect (PAVSD),1 patient with tetralogy of Fallot (TOF) and 1 patient with doubleoutlet right ventricle (DORV). Among different conduit materials,autologous pericardium was used for 17 patients,Gore-Texsynthetic graft was used for 5 patients,and bovine jugular vein was used for 2 patients. Conduit size and children’s body weight were analyzed with linear regression,then the equation was corrected with McGoon ratio. Results There was no perioperative death. Postoperative percutaneous saturation (SpO2)of the 24 children was 20.37%±28.33% higher than preoperative SpO2 . Electrocardiogram showed sinus rhythm in all the patients. Twenty-three patients were NYHA classⅡ,and 1 patient was NYHA classⅢ. Postoperative mechanical ventilation time of patients with autologous pericardium were significantly shorter than those of patients with other 2 materials (P=0.017). Sixteen patients were followed up from 10 months to 2 years after discharge,including 12 patients with autologous pericardium,3 patients with Gore-Tex synthetic graft and 1 patient with bovine jugular vein. During follow-up,McGoon ratio of patients with autologous pericardium,Gore-Tex synthetic graft and bovine jugular vein were 1.98±0.46,1.83±0.33 and 1.68 respectively,all of which weresignificantly higher than preoperative McGoon ratio (P<0.05). Six patients underwent radical corrective surgery,including5 patients with autologous pericardium and 1 patient with Gore-Tex synthetic graft. There was no complication directly related to surgery during follow-up. Linear regression was performed to form an equation between suitable conduit size and patients’ body weight:conduit diameter (mm)=0.327×body weight (kg)+4.599. McGoon ratio,conduit size and equationresult were compared to find a practical choice of conduit size. If McGoon ratio<0.8,the first integer greater than the equation result could be chosen. If McGoon ratio>1.2,the first integer less than the equation result could be chosen. If 1.2>McGoon ratio>0.8,the first integer either less or greater than the equation result could be chosen. Group analysis showed that patients who recovered better postoperatively were those whose conduit sizes were closer to equation results as well as equation results corrected with McGoon ratio. Conclusion All the 3 materials can be conventionally chosen for RV-PA shunt. Appropriate conduit size can be decided upon patients’ body weight and McGoon ratio for RV-PA shunt.

  • Coronary Artery Bypass Grafting: A Report of 253 Patients

    Abstract: Objective To summarize the 17-year clinical experience of coronary artery bypass grafting (CABG). Methods From April 1987 to May 2004, total 253 patients with coronary artery disease underwent CABG. The operation were performed in 217 patients under cardiopulmonary bypass (CPB) with moderate hypothermia, because of calcified ascending aorta, partial replacement of ascending aorta wall with apiece of Gore-Tex graft for the proximal anastomosis were done in 10 patients. Off-pump coronary artery bypass grafting (OPCAB) were performed in 30 patients. The operation under CPB with heart beating were performed in 6 patients. Cardiac valvular operations were performed in 15patients. Left atrium myxoma operation was performed in 1 patient. Left ventricular aneurysm plasty operation were performed in 10 patients. Results Total mortality rate was 7.9% (20/253). There was significant difference between the mortality rate of the first 10 years (16.0%,8/50) and that of the last 7 years (5.9%,12/203; χ2=5.62,Plt;0.05). The causes of death were: 3 patients died on table because of low cardiac output after valvular replacement though emergent CABG were conducted, 2 patients died of multiple organ failure after valvular replacement and emergent CABG had undergone, 3 patients died of ventricular fibrillation during closing the sternum, 6 patients died of multiple organ failure caused of severe lung infection, 2 patients died of ventricular fibrillation after operation, and 4 patients died of acute renal failure. One hundred and fiftyseven patients (67.4%, 157/233) were followed up, follow-up time was 6 months to 15 years. Three of them died of unknown causes, most of them have improved life quality. There were 87 patients in New York Heart Association (NYHA) class Ⅰ, 49 patients in NYHA class Ⅱ, 16 patients in NYHA classⅢ, and 2 patients in NYHA classⅣ. Conclusion When the experience of surgery and postoperative care is matured, CABG is a safe method for treatment of coronary artery disease. Partial replacement of ascending aorta wall with GoreTex graft for proximal anastomosis of the graft is acandidate method for the treatment of patients with calcified ascending aorta.

  • Application of Gore-Tex Patch in Chest Wall Reconstruction

    Abstract: Objective To summarize the application experience of Gore-Tex patch in clinical chest wall reconstruction. Methods A retrospective analysis was performed in 33 patients who underwent chest wall reconstruction using Gore-Tex patch from January 2001 to December 2010 in Shanghai Changhai Hospital, Second Military Medical University. There were 19 men and 14 women, ranging in age from 20 to 73 years with a median age of 45.7 years. The surgical strategies included choosing different incisions according to tumor location and size, and preserving normal chest wall soft tissue as much as possible during surgery. Gore-Tex patch was used to reconstruct the huge chest wall defect, and covered by transferred muscle flaps. Results All the 33 patients underwent surgical reconstruction successfully and there was no perioperative death. Complete tumor resection was performed in all the patients, including 25 patients with malignant tumor and 8 patients with benign tumor. The diameter of the resected tumors ranged from 8 to 20 cm. All the patients were followed up from 5 to 60 months, except that 3 patients (9.09%) were lost during follow-up. There was no rejection response, abnormal breathing and foreign body sensation during follow-up. The infection incidence was 3%(1/33). Conclusion Gore-Tex patch is a safe and effective material for chest wall reconstruction due to its excellent biocompatibility. Appropriate selection of muscle flap for covering Gore-Tex patch can reduce postoperative complications.

  • Outcome of Short and Middle Term of Right Ventricular Outlet Tract Reconstruction with Gore-Tex Monocusp Valve

    Abstract: Objective To evaluate the outcome of reconstruction of right ventricular outlet tract (RVOT) with 0.1 mm Gore-Tex monocusp valve for short and middle term. Methods Between June 2002 to July 2006, 48 patients underwent reconstruction of RVOT with Gore-Tex monocusp valve to correct cardiac anomalies, including 33 patients with tetralogy of Fallot (TOF) and pulmonary stenosis, 8 patients with TOF and pulmonary atresia, 3 patients with TOF and absent pulmonary valve, 2 patients with double outlet of right ventricle and pulmonary stenosis, 1 patient with truncus arterious and 1 patient with complete transposition of great artery, ventricular septal defect and pulmonary stenosis. Results There was no operative death. The postoperative blood oxygen saturation was up to 1.00. The ratioes of right ventricular systolic pressure and left ventricular systolic pressure were between 0.22 to 0.65.The gradient between right ventricle and left or right pulmonary artery was less than 10 mmHg. All patients were followed up including echocardiography ranged from 3 to 48 months. There were no late death and complication. Trivial and mild pulmonary insufficiency was detected in 18 patients and valvular motion remained competent in 40 patients. Conclusion The results suggest that the reconstruction of RVOT with Gore-Tex monocusp valve can achieve excellent outcome for short and middle term.
