Objective: To analyze the feasibility and safety of bridge therapy with active fixed electrodes connected to external permanent pacemakers (AFLEP) for patients with infective endocarditis after lead removal and before permanent pacemaker implantation. Methods: A total of 44 pacemaker-dependent patients, who underwent lead removal due to infective endocarditis in our center from January 2015 to January 2020, were included. According to AFLEP or temporary pacemaker option during the transition period, patients were divided into AFLEP group or temporary pacemaker group. Information including age, sex, comorbidities, indications and types of cardial implantable electionic device (CIED) implantation, lead age, duration of temporary pacemaker or AFLEP use, and perioperative complications were collected through Haitai Medical Record System. The incidence of pacemaker perception, abnormal pacing function, lead perforation, lead dislocation, lead vegetation, cardiac tamponade, pulmonary embolism, death and newly infection of implanted pacemaker were compared between the two groups. Pneumothorax, hematoma and the incidence of deep vein thrombosis were also analyzed. Results: Among the 44 patients, 24 were in the AFLEP group and 20 in the temporary pacemaker group. Age was younger in the AFLEP group than in the temporary pacemaker group (57.5(45.5, 66.0) years vs. 67.0(57.3, 71.8) years, P=0.023). Male, prevalence of hypertension, diabetes mellitus, chronic renal dysfunction and old myocardial infarction were similar between the two groups (all P>0.05). Lead duration was 11.0(8.0,13.0) years in the AFLEP group and 8.5(7.0,13.0) years in the temporary pacemaker group(P=0.292). Lead vegetation diameter was (8.2±2.4)mm in the AFLEP group and (9.1±3.0)mm in the temporary pacemaker group. Lead removal was successful in all patients. The follow-up time in the AFLEP group was 23.0(20.5, 25.5) months, and the temporary pacemaker group was 17.0(14.5, 18.5) months. In the temporary pacemaker group, there were 2 cases (10.0%) of lead dislocation, 2 cases (10.0%) of sensory dysfunction, 2 cases (10.0%) of pacing dysfunction, and 2 cases (10.0%) of death. In the AFLEP group, there were 2 cases of abnormal pacing function, which improved after adjusting the output voltage of the pacemaker, there was no lead dislocation, abnormal perception and death. Femoral vein access was used in 8 patients (40.0%) in the temporary pacemaker group, and 4 patients developed lower extremity deep venous thrombosis. There was no deep venous thrombosis in the AFLEP group. The transition treatment time was significantly longer in the AFLEP group than in the temporary pacemaker group (19.5(16.0, 25.8) days vs. 14.0(12.0, 16.8) days, P=0.001). During the follow-up period, there were no reinfections with newly implanted pacemakers in the AFLEP group, and reinfection occurred in 2 patients (10.0%) in the temporary pacemaker group. Conclusions: Bridge therapy with AFLEP for patients with infective endocarditis after lead removal and before permanent pacemaker implantation is feasible and safe. Compared with temporary pacemaker, AFLEP is safer in the implantation process and more stable with lower lead dislocation rate, less sensory and pacing dysfunction.

In this study, two school-aged children had an acute onset in spring and had the manifestations of fever, headache, vomiting, disturbance of consciousness, purpura and ecchymosis, and positive meningeal irritation sign. There were increases in peripheral white blood cells and neutrophils, but reductions in the hemoglobin level and platelet count in the two children. They had a significant increase in C-reactive protein. There were hundreds or thousands of white blood cells in the cerebrospinal fluid, mainly neutrophils. Increased protein contents but normal levels of glucose and chloride in the cerebrospinal fluid were found. Head CT scan showed multiple hematomas in the right cerebellum and both hemispheres in one child. Bone marrow cytology indicated infection in the bone marrow, and both blood culture and bone marrow culture showed methicillin-resistant Staphylococcus aureus (MRSA). Both patients had cardiac murmurs and progressive reductions in the hemoglobin level and platelet count during treatment, and echocardiography showed the formation of vegetation in the aortic valve. Therefore, the patients were diagnosed with infectious endocarditis (IE). Vancomycin was used as the anti-infective therapy based on the results of drug sensitivity test. One child was cured after 6 weeks, and the other child was withdrawn from the treatment and then died. Dynamic monitoring of cardiac murmurs should be performed for children with unexplained fever, and echocardiography should be performed in time to exclude IE. IE should also be considered for children with purulent meningitis and skin and mucosal bleeding which cannot be explained by the reduction in platelet count.

4.Emphasize the diagnosis and treatment of infective endocarditis in patients with severe burn.
Chinese Journal of Burns 2016;32(2):74-76
The incidence and mortality of infective endocarditis (IE) in patients with severe burn remain high, which are attributed to invasive procedures, bacteremia, and wound infection after burns. Clinical clues for IE in burns are usually masked by burn-related manifestations, so the diagnosis of IE may be delayed or missed. For burned patients with persistent bacteremia of unknown source, especially Staphylococcus aureus-induced bacteremia, the diagnosis of IE should be considered according to the Duke criteria, and early echocardiography performance is particularly important. Antibiotic therapy is the mainstay initial management, and early surgical intervention is strongly recommended once IE is clearly diagnosed in patients with burns. In order to lower the incidence and mortality of IE in burns, it is very important to take prophylactic procedures along with the whole course of burn management.

5.A case of left atria subendocardial thrombus with sick sinus syndrome.
Journal of Central South University(Medical Sciences) 2016;41(9):1005-1008
The clinical data for a patient with sick sinus syndrome was retrospectively analyzed. The patient was treated because of his heart palpitations and the increased chest pain. The patient admitted to the hospital under consideration for the left atrial tumor dependent on the echocardiography findings. After the CT scan and the dynamic ECG examination, the patient successfully underwent the left atrial tumor resection, atrial septal repair and cardiac pacing lead installation. The postoperative pathological diagnosis showed that the infective endocarditis and left atrial thrombus in left atrium was cured. The patient was discharged after postoperative anti-inflammatory therapy. By analyzing the reasons for misdignosis before or during surgery, the possible mechanisms for left atrial subendocardial thrombus have been found. This study suggests that it is necessary to combine imaging diagnosis and clinical observations to distinguish tumor from excrescence.

OBJECTIVETo investigate the result of surgical treatment of active infective endocarditis in patients with recent cerebrovascular events, and to evaluate the optimal indication and timing of surgical intervention.
METHODSThe clinical data of 26 patients with cerebrovascular complications before surgery Between December 2007 and December 2013 were analyzed retrospectively. There were 17 male and 9 female patients, aged (42±14) years. Types of disease included single aortic valvular disease (n=8), single mitral valvular disease (n=12), multiple valvular disease (n=5), and aortic valvular disease with ventricular septal defect (n=1). Type of cerebrovascular complication included cerebral infarction (n=25) and cerebral hemorrhage (n=1). Thirty-one valves were involved in 26 patients, mechanical prosthetic valve replacement (n=25), bioprosthetic valve replacement (n=4), and mitral valve repair (n=2).
RESULTSThe interval between onset of cerebrovascular event and surgical intervention was less than 14 days (n=3), 14 to 21 days (n=13), over 21 days (n=10), and the mean was (20±4) days. There were 33 vegetations found intraoperatively. The mean size of vegetations was (10±4) mm and 19 were found in mitral valve. Two patients died in hospital. One case relapsed after 1 year and underwent reoperation for prosthetic valve endocarditis. The remaining patients recovered with cardiac function of New York Heart Association class I to II after the period of 3 months to 5 years follow-up.
CONCLUSIONSAppropriate surgery may effectively improve the outcome of IE patients with cerebrovascular complications. The surgical indications and risks of further neurologic deterioration after cardiac surgery should be assessed comprehensively before surgical intervention.

We received a patient who repeated unconsciousness due to excrescence locking bicuspid aortic valve. He experienced unconsciousness and treatments with anti infection, surgical operation, valve replacement and recovery. It was a rare case, which made us realize that the heart color Doppler ultrasound should be regularly performed in patients with aortic valve abnormalities. Once patients were found to have infective endocarditis combined with the valve vegetations, they should be formally treated as soon as possible.
