ObjectiveSurgical radiofrequency (RF) ablation has recently been one of the most effective means to treat chronic atrial fibrillation(AF).However,about 20％ to 30％ patients have shown recurrence of AF during the follow-up period.This study retrospectively analyzed AF recurrence rate in those patients who underwent valve replacement procedures combined with RF ablation to treat AF in our department during the last three years.We compared the information and clinical date in the sinus rhythm(SR) group with in the AF recurrence group to analyze the relationship between various preoperative risk factors and operation failure.The aim of this study is to provide evidences to select patients who can benefit most from this type of surgery and to reduce their surgical risk and hospital charges.MethodsFrom June 2006 to June 2009,52 patients with rheumatic heart disease (RHD) and chronic AF underwent RF ablation concomitant with valve replacement in our department by a same surgeon with the same method.Preoperative and intraoperative data was retrospectively collected and all patients were followed up longer than six months to determine the type of heart rhythm.Operation failure was defined as showing any rhythm except normal sinus rhythm by electrocardiogram.We divided all patients to the SR grope and AF grope.Univariate and multivariate statistical analysis was used to compare the data between the two groups in pre-,intra- and postoperative period.Results There was only one case in-hospital mortality ( 1.9％ ).None mortality,re-exploration for bleeding and pacemaker implantation for malignant arrhythmia was shown during the mean follow-up period of 14 months (9-35 months).At the last follow-up,sinus rhythm was shown in 71.2％ (37/52) patients.In univariaye analysis,the left atrial diameter,AF duration,left ventricular end diastolic volume and aortic cross-clamp were predictors of recurrence of AF.Age,left ventricular ejection factor,cardiopulmonary bypass time showed no significant difference between the two gropes.Multivariate analysis showed that AF duration was the independent risk factor of recurrence of AF after the bipolar radiofrequency ablation procedure.ConclusionRF ablation concomitant with valve replacement is an effective way to treat AF for those patients who need open heart surgery at the same time.Patients with normal SR may gain a better life quality.Preoperative duration of AF was the independent risk factor of AF recurrence.The longer the duration of AF is,the worse the efficacy of this procedure to restore normal SR is.

Objective: To summarize the clinical experience of artificial vascular sleeve-like inverted suture in proximal part of ascending aorta, and to explore the effectiveness of the method. Methods: A retrospective study was performed. From August 2017 to April 2018, 10 patients with Stanford type A aortic dissection with surgical indications for ascending aortic replacement were treated with artificial vascular sleeve-like inverted suture for proximal part of ascending aorta, 9 cases of emergency operation, 8 cases of males and 2 females, aged 43-69 years, mean(51±6) years old. The specific method for operation is to invert the artificial blood vessel 2 cm outward and then insert it into the ascending aorta, suture the inverted part of the artificial blood vessel and the ascending aorta continuously. If there is obvious bleeding, stitch strips made of artificial blood vessel or pericardium with theanastomosis ring. The drainage in 24 hours after operation and early postoperative outcome were observed. Results: There was no intraoperative death in the whole group, and there was no second thoracotomy for hemostasis. The drainage volume was 150-880 ml, average(260±55) ml in 24 hours after surgery. One patient developed gastrointestinal hemorrhage after operation, and healed after two times of hemostasis by bedside gastroscopy. Two patients had transient neurological dysfunction(TND). All of the 10 patients were cured and discharged after treatment. All patients were followed up for 1-6 months. All patients underwent transthoracic echocardiography. Eight of them underwent CT angiography, no new aortic regurgitation, and no obvious sinus widening. Conclusion The artificial blood vessel sleeve-like inverted suture is a simple and reliable operation in reinforcement for proximal part of ascending aorta. The anastomosis circle and the suture pinprick are not directly in contact with the blood flow, reducing the chance of bleeding. Even if there is tinybleeding, it will be easy to find and repair. In conclusion, this method is convenient and effective, and it is worthy of clinical promotion.

Objective: To evaluate the mid- and long-term efficacy of Hybrid coronary revascularization (HCR) in the treatment of multi-vessel coronary artery disease for 5 years after operation, and to compare the operative effect with those of off-pump coronary artery bypass grafting (OPCABG) for the same period. Methods: From March 2010 to June 2013, 37 patients underwent selective staging HCR surgery (HCR group) due to multi-vessel coronary artery disease in our hospital. All patients were treated by PCI and MIDCAB subsequently. 148 patients with OPCABG completed by the same group of doctors at the same time were served as control group (OPCABG group), and the follow-up period was up to June 2018. The end point of the study was the incidence of major adverse cardiac or cerebrovascular events (MACCE) events in both groups, including cardiac death, new myocardial infarction, secondary coronary revascularization and cerebrovascular accident. Results: The clinical baseline data of the two groups were basically matched. 37 patients in HCR group were successfully operated on, and each patient was completed with LIMA-LAD bypass, 72 drug-eluting stents were implanted. 504 stents were bridged in 148 patients in OPCABG group, each patient was completed with LIMA-LAD bypass, the other target vessels were performed by sequential anastomosis with great saphenous vein as graft. The average follow-up time was 6.3 years (5.1-8.2 years). In HCR group, 33 patients(89%)completed the follow-up, of which 6 (18%) had MACCE events. In OPCABG group, 130 patients(88%)successfully completed the follow-up, of which 19 (15%) had MACCE events. There was no significant difference in MACCE-free survival rate between the two groups (HCR 81.8% vs. OPCABG 73.8%, P>0.05). Conclusion The mid- and long-term effect of HCR is similar to that of OPCABG in the treatment of multi-vessel coronary artery disease, but it has the advantages of less traumatic, faster recovery and less use of blood products. It can be widely used in patients with selective multi-vessel coronary artery disease.

BACKGROUND: Pulmonary thrombosis embolism (PTE) is one of the most severe complications of perioperative radical mastectomy. Massive PTE is often accompanied by shock and hypotension which is characterized by rapid progression and high mortality. There is no standard for the treatment of these patients, which is thoracic surgery, and it is a critical issue in the thoracic surgeons. This article summarizes and analyzes the treatment of two patients with high-risk PTE at the early stage of postoperative lung cancer in our hospital. In addition, we discusses the diagnosis and treatment strategies of these cases to provide a reference for the thoracic surgeons. METHODS: We presented two patients with high-risk PTE at the early stage after thoracic surgery for radical surgery in our hospital back in 2017. One case was treated with intravenous venous interventional thrombolysis, and the other was treated with thrombolysis alone. The treatment effect of two patients and the complications during the treatment has been recorded to detail and summarized. RESULTS: Both patients were female who aged 66 and 61 years old. The time point of pulmonary embolism was 48 h and 45 h after operation, and the time of interventional thrombolysis was 70 minutes and 50 minutes after onset respectively. After 120 minutes and 100 minutes, the drainage after interventional thrombolysis was 4,690 mL and 520 mL respectively. The hospitalization time after thrombolysis was 21 days and 14 days respectively. There was no obvious complication through a follow-up of 6 months. CONCLUSIONS Early postoperative acute massive pulmonary embolism in lung cancer should be treated with pulmonary interventional thrombolysis as soon as possible. Compared with intravenous thrombolysis, pulmonary interventional thrombolysis shows accuracy, easy controlling of dosage, fast curative effect and low bleeding risk.
