  • Research progress of mast cells in the mechanism of intestinal injury caused by deep hypothermic circulatory arrest

    Deep hypothermic circulatory arrest (DHCA) is an important assistant technique for complex cardiac surgery, which creates convenient operating conditions for surgery, and is also one of the measures to protect the brain during operation. However, the complications caused by this technique cannot be ignored, and it should be noticed that the occurrence of intestinal injury is relatively insidious, but brings great pain to patients and significantly reduces the quality of life after operation. Studies have shown that intestinal ischemia-reperfusion injury is induced by DHCA. It causes mast cells to activate and release many inflammatory mediators that destroy the intestinal mucosal epithelium barrier, and eventually lead to intestinal injury. This article reviewed the research progress of mast cells in the mechanism of DHCA-induced intestinal injury.

  • Result of surgical treatment of hypertrophic obstructive cardiomyopathy with coronary heart disease

    ObjectiveTo summarize the perioperative management strategies and early results of modified Morrow expanded operation and coronary artery bypass grafting (CABG) in patients with hypertrophic obstructive cardiomyopathy (HOCM) and coronary atherosclerotic heart disease.MethodsBetween January 2012 and December 2017, in the Second Inpatient Department of Fuwai Hospital, 32 patients (20 females and 12 males) underwent modified expanded Morrow operation and CABG. The median age was 53.7±8.7 years (interquartile range 37 to 67 years). Preoperative chest distress symptom was found in 24 patients, chest pain symptom was found in 14 patients, history of syncope in 6 patients. Cardiac echocardiography, electrocardiogram, chest X-ray, magnectic resonance imaging (MRI) were performed routinely after operation and follow-up to analyze structure and function of heart and mitral valve.ResultsAll patients underwent modified and expanded Morrow combined with CABG. The preoperative left ventricular outflow tract peak pressure difference (LVOTG) was 40 to 152 (79.6±28.7) mm Hg. Four patients underwent myocardial bridge releasing in the same period, mitral valve replacement in 2 patients, mitral valve angioplasty in 3 patients, Maze operation in 2 patients and tricuspid valveoplasty in 3 patients. There was no hospital mortality. CABG surgery in patients with branches included anterior descending artery in 26 patients, diagonal branch in 16 patients, left circumflex in 8 patients, right coronary artery in 11 patients. There were 15 patients with one coronary artery (CA) bypass graft, 5 patients with two CA bypass grafts, and 12 patients with 3 CA bypass grafts. The average of CA bypass grafts was 1.9±0.6. The postoperative ICU time ranged from 1–13 (4.1±2.8) days and postoperative hospital stay ranged from 7 to 30 (12.6±5.5) days. No severe postoperative complications were found and 1 patient had postoperative incision healing. The postoperative new arrhythmia included left bundle branch block in 6 patients. Compared with the preoperative values, postoperative left ventricular outflow tract peak pressure (79.6±28.7 mm Hg vs. 10.8±5.9 mm Hg, P<0.001), interventricular septum thickness (1.9±0.4 cm vs. 1.3±0.5 cm, P<0.001) were decreased obviously. Mitral valve closure is good or only mild reflux, mitral valve forward movement (SAM sign) disappeared. The patients were followed up for 6-68 months, with an average of 38.8±20.6 months. All patients were followed up with symptoms disappeared or only mild symptoms. NYHA classification decreased Ⅰ to Ⅱ grade after surgery, without long-term mortality, complications or reoperation.ConclusionFor patients with hypertrophic obstructive cardiomyopathy with coronary atherosclerotic heart disease, the application of improved expand morrow operation at the same time undergoing coronary artery bypass grafting is safe. It can significantly improve patients' survival and reduce symptoms, play a synergistic effect, and do not increase the patient's surgical complications.

  • Advances in antithrombotic therapy in patients with valvular heart disease after transcatheter intervention

    As technology advances, current evidence supports the use of devices for valvular heart disease interventions, including transcatheter aortic valve implantation, transcatheter mitral or tricuspid valve repair, and transcatheter mitral valve implantation. These procedures require antithrombotic therapy to prevent thromboembolic events during the perioperative period, and these therapies are associated with an increased risk of bleeding complications. To date, there are challenges and controversies regarding how to balance the risk of thrombosis and bleeding in these patients, and therefore the optimal antithrombotic regimen remains unclear. In this review, we summarize the current evidence for antithrombotic therapy after transcatheter intervention in patients with valvular heart disease and highlight the importance of an individualized approach in targeting these patients.

  • Meta-analysis of non-vitamin K antagonist oral anticoagulant vs. vitamin K antagonist treatment in patients after transcatheter aortic valve implantation with high-risk atrial fibrillation: Systematic review and meta analysis

    ObjectiveTo systematically evaluate the effects of non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA) on postoperative anticoagulation in patients undergoing transcatheter aortic valve implantation (TAVI) with combined high-risk atrial fibrillation (AF). MethodsAll clinical research literature on NOAC and VKA in TAVI patients with high-risk AF was collected using computer searches of PubMed, EMbase, The Cochrane Library, CNKI, VIP, and SinoMed. The retrieval schedule was from inception to January 2023. The Newcastle-Ottawa Scale (NOS) was utilized to provide an assessment of the quality of the included literature. Meta-analysis was performed by applying RevMan 5.4 software to the studies that met the quality criteria. ResultsA total of 24 592 patients were incorporated in 7 eligible papers for meta-analysis. Patients with NOAC had a significantly lower risk of all-cause mortality compared with TAVI patients with combined high-risk AF who had VKA [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. During the first year of follow-up, no apparent difference in all-cause mortality was observed between the two groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]. After a year of following up on patients treated with VKA, all-cause mortality was higher in the group treated with NOAC, and the difference was statistically meaningful [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. Patients in both groups had early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], follow-up stroke [RR=1.04, 95%CI (0.88, 1.22), P=0.64] and bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], severe or life-threatening hemorrhage [RR= 0.80, 95%CI (0.49, 1.31), P=0.38], and acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24] were all non-statistically significant differences. ConclusionCompared with the application of VKA, postoperative anticoagulation with NOAC in TAVI patients with combined high-risk AF may reduces all-cause mortality in patients and may yield additional benefit especially in long-term anticoagulation.

  • Risk Stratification Management of Pediatric Patients with Prolonged Postoperative Recovery after Total Cavopulmonary Connection

    Objective To investigate clinical features and risk factors of prolonged postoperative recovery of pediatric patients in ICU after total cavopulmonary connection(TCPC),provide evidence for risk stratification management strategy, and enhance their postoperative recovery. Methods We conducted a retrospective analysis of clinical data of 81 patients undergoing TCPC in Fu Wai Hospital from January 2010 to July 2012. Three patients who died postoperatively were excluded from analysis. Prolonged postoperative recovery was defined as patients whose postoperative mechanical ventilation time was longer than that of 75% of all the patients. A total of 78 patients were divided into normal recovery group and prolonged recovery group. There were 59 patients in the normal recovery group including 34 male and 25 female patients with their age of 62.5±20.7 months,and 19 patients in the prolonged recovery group including 11 male and 8 female patients with their age of 64.8±29.8 months. Perioperative variables were compared between the two groups. Results The average cardiopulmonary bypass time of all the 81 patients was 107.6±54.1 (33-350) minutes. The average aortic cross-clamping time of 17 patients was 46.4±31.5 (22-143) minutes. Three patients (3.7%) died postoperatively because of severe low cardiac output syndrome and thrombosis in the extracardiac conduit. The mechanical ventilation time and ICU stay were 7.5 hours and 1.6 days respectively in the normal recovery group,which were both significantly prolonged in the prolonged recovery group. Preoperative high hemoglobin level,coexistence of intracardiac anomalies,longer cardiopulmonary bypass time,and non-fenestrated procedure were the main risk factors of prolonged postoperative recovery. Conclusion Early extubation and fast track recovery can be achieved in most of TCPC patients. Risk stratification management strategies may contribute to successful postoperative recovery of critical patients after TCPC.

  • The distribution and drug-resistance of pseudomonas aeruginosa in Fuwai Hospital of Chinese Academy of Medical Sciences from 2013 to 2016

    Objectives To retrospectively analyze the isolation rate and drug-resistance of pseudomonas aeruginosa in Fuwai Hospital of Chinese Academy of Medical Sciences from 2013 to 2016. Methods The specimens were collected and cultured. If the isolated bacteria were from the same part of the same patient, the first isolated strains were only counted. The isolated pathogens were identified and the drug-resistance were analyzed. Results A total of 1 404 pseudomonas aeruginosa were isolated. The majority of them were from postoperative recovery room of surgery department (62.1%) and ICU of internal medicine (22.3%). The specimen source were mainly from respiratory tract (75.7%), followed by blood (10.0%) and venous catheter (5.5%). The resistance rate of piperacillin and piperacillin/sulbactam to pseudomonas aeruginosa was 0.6% to 10.4%. The resistance rate of ceftazidime and cefepime was 0.3% to 11.7%. The resistance rate of imipenem and meropenem was 7.6% to 20.1%. The resistance rate of amikacin, gentamicin, and tobramycin was 0.3% to 3.2%. The resistance rate of ciprofloxacin and levofloxacin was 0.6% to 5.2%. Conclusions The isolates of pseudomonas aeruginosa are mainly from postoperative recovery room of surgery department and ICU of internal medicine . Imipenem and meropenem are not the best choices for pseudomonas aeruginosa infection. It has great value to combine piperacillin, piperacillin/sulbactam, ceftazidime and cefepime with aminoglycoside or quinolone antibiotics for the treatment of pseudomonas aeruginosa infection which will reduce drug resistance.

  • Risk factors of prolonged ventilation in adults after atrioventricular septal defect operation

    Objective To investigate the risk factors of prolonged postoperative mechanical ventilation for adult patients with atrioventricular septal defect (AVSD). Methods We retrospectively analyzed the clinical data of 76 patients with AVSD aged more than 18 years in our hospital from January 1, 2011 to December 31, 2017. The patients ventilated longer than 24 hours were described as a prolonged ventilation group (n=27) and the others as a normal group (n=49). There were 9 males and 18 females aged 32.22±9.64 years in the prolonged ventilation group, and 16 males and 33 females aged 35.98±11.34 years in the normal group. Perioperative variables between the two groups were compared and selected, and then analyzed by logistic regression analysis. Results The result of univariate analysis showed that there was a statistical difference in weight, preoperative pulmonary artery systolic pressure, duration of cardiopulmonary bypass, the level of postoperative platelet, hemoglobin, blood glucose, lactic acid and serum creatinine, postoperative maximum heart rate and postoperative infection rate between the prolonged ventilated group and the normal group. Multivarable logistic regression showed that preoperative pulmonary artery hypertension (OR=1.056, 95%CI 1.005 to 1.110, P=0.030), prolonged duration of cardiopulmonary bypass (OR=1.036, 95%CI 1.007 to 1.066, P=0.016) and the low postoperative hemoglobin level (OR=0.874, 95%CI 0.786 to 0.973, P=0.014) were the risk factors of prolonged postoperative mechanical ventilation. Conclusion Preoperative pulmonary artery hypertension, long duration of cardiopulmonary bypass and postoperative anaemia are the risk factors associated with prolonged postoperative mechanical ventilation.
