Objective To summarize the research progress of the adenocarcinoma of esophago-gastric junction (AEG) in recent years, in order to improve the further understanding of this disease. Method The literatures about application and research progress of AEG were researched and reviewed. Results Siewert classification was a widely recognized classification for AEG, according to this classification, AEG was divided into typeⅠ, Ⅱ, and Ⅲ. Gastroesophageal reflux, Barrett’ sesophagus, and the infection of Helicobacter pylori may be the important pathogenic factors. For SiewertⅠAEG, thoracic approach was preferred commonly, and for SiewertⅡand Ⅲ AEG, total gastrectomy through abdominal approach and distal partial resection of esophagus through diaphragmatic hiatus approach were recommended. Endoscopic submucosal resection, neoadjuvant therapy, targeted therapy, and multidisciplinary team were becoming more and more important in the treatment of AEG. Conclusions The choice of surgical method and resection range should according to the types of AEG. Comprehensive assessment and comprehensive treatment would be performed, so that effect of treatment may be improved.
ObjectiveTo explore clinical features and surgical strategies for patients with aortic dissection (AD) manifesting as pure aortic regurgitation (AR), avoid preoperative misdiagnosis, and provide reference for clinical diagnosis and treatment. MethodsClinical data of 5 AD patients who were preoperatively diagnosed as pure AR in Beijing Fu Wai Hospital from January 2005 to May 2012 were retrospectively analyzed. There were 4 male and 1 female patients with their median age of 41 (34-53) years. All the 5 patients were diagnosed as AD during the operation. One patient received aortic valvuloplasty, 1 patient received Wheat procedure, and 3 patients received Bentall procedure. Clinical manifestations, accessory examinations, intraoperative findings, surgical strategies and follow-up results were summarized. ResultsNo postoperative death or complication occurred in this study. Echocardiogram of patient 1 before discharge showed that transverse diameters of the ascending aorta and aortic sinus decreased with satisfactory closure of aortic valves but no AR. Echocardiogram and CT all showed normal function in mechanical valves and patent blood vessel prosthesis in the other 4 patients. All the 5 patients were followed up for 4 (1-5) years and were alive during follow-up. Echocardiogram showed normal function in mechanical valves and patent blood vessel prosthesis without paravalvular leak in 4 patients and mild AR in 1 patient. ConclusionAD manifesting as pure AR is rare and easily misdiagnosed preoperatively. Careful analysis of medical history and accessory examinations can reduce the risk of misdiagnosis. Appropriate surgical strategies should be chosen according to intraoperative findings of intimal tears and aortic sinus damage of AD.
ObjectiveTo investigate clinical outcomes of mitral valvuloplasty (MVP)for the treatment of infective endocarditis (IE)and mitral regurgitation (MR). MethodsFrom March 2002 to January 2012, 33 patients with IE and MR underwent MVP in Fu Wai Hospital. There were 23 male and 10 female patients with their age of 10-67 (35.7±17.8)years. Thirteen patients had previous cardiac anomalies. Preoperatively, there were 5 patients with mild MR, 15 patients with moderate MR and 13 patients with severe MR. There were 5 patients in New York Heart Association (NYHA)functional classⅠ, 23 patients in classⅡ, 4 patients in classⅢ and 1 patient in classⅣ. All the patients received MVP including 14 patients received MVP in active phase of IE. Concomitantly, 6 patients received aortic valve replacement, 5 patients received tricuspid valvuloplasty, 1 patient received coronary artery bypass grafting, 1 patient received resection of left atrial myxoma and 1 patient received repair of aortic sinus aneurysm. Surgical procedures included pericardial patch closure of leaflet perforation in 5 patients, leaflet excision and suturing in 17 patients, double-orifice method in 3 patients, chordae transfer and artificial chordae implantation in 5 patients, and annuloplastic ring implantation in 15 patients. ResultsOne patient died of acute myocardial infarction 7 days after the operation. All other 32 patients were successfully discharged. Echocardiography before discharge showed left ventricular end-diastolic diameter (LVEDD, 48.9±7.6 mm)and left atrial diameter (LAD, 31.7±7.4 mm)were significantly smaller than preoperative values (P=0.000). Thirty-two patients were followed up for 6-125 (73.0±38.6)months. There was no death, IE recurrence, bleeding or thromboembolism during follow-up. One patient received mitral valve replacement for mitral stenosis 3 years after discharge. There were 25 patients in NYHA func-tional classⅠ, 5 patients in classⅡand 2 patients in classⅢ. There were 4 patients with mild MR, 1 patient with moderate MR, and 26 patients had no MR. One patient had faster mitral inflow at diastolic phase (1.7 m/s). One patient had moderate aortic regurgitation. LVEDD and LAD during follow-up were not statistically different from those before discharge. Left ventricular ejection fraction during follow-up was significantly higher than that before discharge (60.9%±6.6% vs. 57.5%±6.7%, P=0.043). ConclusionMVP is a reliable surgical procedure for patients with IE and MR, and can significantly reduce left atrial and left ventricular diameter and improve cardiac function postoperatively.
Objective To compare the in-hospital and midterm outcomes after simultaneous hybrid coronary revascularization (HCR) with off-pump coronary artery bypass grafting (OPCAB) in diabetic patients with multivessel coronary artery disease. Methods One hundred thirty-two diabetic patients with multivessel coronary artery disease underwent one-stop HCR at Fuwai Hospital from January 2010 to January 2015. These patients were 1∶2 matched with those who underwent OPCAB using propensity score matching. Results Simultaneous HCR had less chest tube drainage (618 (420, 811) ml vs. 969 (711, 1 213)ml, P<0.001), lower transfusion rate (19.7%vs. 34.1%, P=0.026), shorter mechanical ventilation time (11.6 (8.2, 14.8) h vs. 16.0 (12.1, 18.7) h, P<0.001), and shorter stay in intensive care unit (21.5 (18.8, 42.0) hvs. 44.6 (23.7, 70.1) h, P<0.001) than OPCAB. During over median 40 months follow-up, simultaneous HCR offered similar major adverse cardiac or cerebrovascular events (MACCE) rate (6.8%vs 9.0%, P=0.826), but lower stroke rate (0% vs 3.0%, P=0.029), compared with OPCAB. Conclusion For selected patients with diabetes, simultaneous HCR provides a safe and effective revascularization alternative. It decreases perioperative invasiveness and incurred similar and favorable midterm outcomes with OPCAB.
ObjectiveTo investigate the early clinical results of MitraClip system in domestic patients. Methods We retrospectively analyzed the clinical data of 36 patients who underwent transcatheter edge-to-edge repair procedure using MitraClip system in Beijing Fuwai Hospital, Shenzhen Fuwai Hospital and Fuwai Yunnan Cardiovascular Hospital between January and June 2021. There were 24 males and 12 females, with a median age of 70 (47-86) years. Ten (27.8%) patients had 3+ mitral regurgitation (MR) and 26 (72.2%) patients had 4+ MR preoperatively. ResultsAll procedures were successfully performed. The reduction in MR was 2+ at least immediately after surgery, and 91.7% of patients had MR≤2+ at 3 days postoperatively. There was no statistical difference in left ventricular ejection fraction change postoperatively. Forward velocity and peak gradient of mitral valve were increased after the procedure. Mean gradient of mitral valve were increased at 3 days postoperatively than immediately after surgery (P<0.001). Two patients had acute pericardial effusion intraoperatively, and received pericardial puncture and drainage immediately. ConclusionMitraClip system has been applied well in domestic patients and can significantly improve MR. This sutdy has a good consistency with foreign studies, and the early results are satisfactory.
