Objective To formulate an individualized evidence-based treatment for a first-diagnosed patient with coronary artery-pulmonary artery fistula. Methods Aiming at the issue of whether interventional operation was necessary for first-diagnosed coronary artery-pulmonary artery fistula or not, the computer retrieval was conducted in the US National Guideline Clearinghouse, The Cochrane Library, PubMed and MEDLINE from 1990 to 2011, to collect and assess the best evidence of relevant systematic reviews, randomized controlled trials, controlled clinical trials and treatment guidelines, in order to be applied in clinical treatment. Results There were 1 clinical guideline for treating coronary artery fistula and 3 different high-quality evidence studies were retrieved. The results showed percutaneous coronary intervention was the best treatment currently. According to the obtained evidence and patient’s willingness, the relevant examinations were taken, and the preoperative preparation for percutaneous coronary intervention was done actively after the patient was admitted. Three days after hospitalization, the selective coronary angiography showed right coronary artery-pulmonary artery fistula and left coronary circumflexus artery-left atrial multiple fistulae, then the percutaneous coronary intervention spring coil embolization was successfully conducted for right coronary artery-pulmonary artery fistula. After operation, bayasprin enteric-coated tablets 0.1 g/d was taken for anti-platelet aggregation and preventing thrombotic diseases. The observation during operation and postoperative 5-day hospitalization showed no relevant complications. Conclusion Percutaneous coronary intervention is safe and effective for the symptomatic patients with coronary artery-pulmonary artery fistula.
Objective To compare the effectiveness, complications, and follow-up results between endovascular recanalization (EVR) and open surgical revascularization (OSR) in the treatment of peripheral pseudoaneurysm, so as to provide a reference for choosing a appropriate surgical procedure. Methods Clinical data of 62 cases of peripheral pseudoaneurysm between January 2001 and January 2012 were analyzed retrospectively. EVR was performed in 28 patients (EVR group) and OSR in 34 patients (OSR group). There was no significant difference in gender, age, cause of injury, tumor location, and diameter of tumor between 2 groups (P gt; 0.05). Results The operation time, blood loss, ICU monitoring time, and hospitalization time in EVR group were significantly shorter than those in OSR group (P lt; 0.05). In OSR group, 12 cases (35.29%) had early postoperative complications, including 2 deaths due to acute respiratory distress syndrome, 5 cases of pulmonary infection, 3 cases of wound infection, and 2 cases of deep vein thrombosis; in EVR group, 2 cases (7.14%) had early postoperative complications, including 1 case of hematoma at puncture site and 1 case of thrombosis in stent. There was significant difference in early postoperative complication incidence between 2 groups (χ2=6.691, P=0.008). The patients were followed up 12-39 months (mean, 26 months). In OSR and EVR groups after operation, the patency rates of the reconstructed vessels were 96.88% (31/32) and 92.86% (26/28) respectively at 12 months, showing no significant difference (χ2=0.014, P=0.905); the patency rates were 89.29% (25/28) and 84.00% (21/25) respectively at 24 months, showing no significant difference (χ2=0.322, P=0.570). Conclusion Compared with OSR, EVR is a minimally invasive, safe, and effective therapy for peripheral pseudoaneurysm with the advantages of less bleeding, shorter hospitalization time, and less complications. Long-term effectiveness still needs further observation, and patients have to take antiplatelet drugs for long time after EVR.
Objective To assess the effectiveness and safety of different dual antiplatelet therapies in patients undergoing percutaneous coronary intervention. Methods Such databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched to collect the randomized controlled trials (RCTs) and observational studies on the effectiveness and safety of dual antiplatelet therapies both short-duration (≤6 months) and long-duration (gt;6 months) after percutaneous coronary intervention. The literature was screened according to the inclusive and exclusive criteria by two reviewers independently, the quality was evaluated, the data were extracted, and meta-analyses were performed by using RevMan 5.1 software. Results Eight trials were included, of which 3 were RCTs involving 7 475 patients, and 5 were observational studies involving 12 744 patients. Meta-analyses on RCTs showed that the incidence of death or myocardial infarction in the long-duration treatment group was lower than that of the short-duration treatment group (OR=0.74, 95%CI 0.56 to 0.98, Plt;0.000 1), while meta-analyses on observation studies showed the similar result (OR=0.7, 95%CI 0.45 to 1.08, P=0.11). With the variables of published year and follow-up time, the heterogeneity of cohort studies was discussed through meta-regression (Z=3.61, P=0.000) which indicated that both published year and follow-up time might be the source of heterogeneity due to their contribution. For RCTs, the incidence of severe bleeding events in the short-duration treatment group was lower than that in the long-duration treatment group (OR=1.29, 95%CI 0.99 to 1.69, P=0.06). For observational studies, the incidence of late stent thrombosis in the long-duration treatment group was lower than that in the short-duration treatment group (OR=0.40, 95%CI 0.15 to 1.07, P=0.07). Conclusion The long duration (gt;6months) of dual antiplatelet therapy in patients undergoing percutaneous coronary intervention can reduce the incidence of death or myocardial infarction and decrease the tendency of late stent thrombosis, but cannot obviously increase the incidence rate of severe bleeding events. The current evidence shows no marked superiority in longer duration (gt;12months) of dual antiplatelet therapy.
Objective To evaluate the efficacy of statins pretreatment in patients before percutaneous coronary intervention (PCI). Methods Published literature on relevant randomized controlled trials (RCTs) were retrieved via electronic and handsearch in databases CNKI, CBM, MEDLINE and The Cochrane Library from January 1990 to May 2011. The references of these articles were also retrieved. Two reviewers independently identified articles according to the inclusion and exclusion criteria, extracted the data, assess the quality of the included studies, and then conducted meta-analysis using RevMan 5.0 software. Results A total of 10 trials involving 3 012 patients were included. The results of meta-analyses showed that: during the periprocedural period, the trial group had a lower incidence than the control group (98 of 1 514 cases, incidence 6.5%) in periprocedural myocardial infarction with a significant difference (OR=0.43, 95% CI 0.34 to 0.56, Plt;0.000 01). The composite of death, myocardial infarction, or target vessel revascularization in one month, essentially driven by periprocedural myocardial infarction, was reported 6.8% in the trial group and 15.1% in the control group (OR=0.41, 95% CI 0.32 to 0.53, Plt;0.000 01). Conclusion Current evidence supports the effectiveness of statin pretreatment used to reducing the rate of periprocedural myocardial infarction in patients before receiving PCI.

Methods Eight pregnant goats with two fetal in each goat were included. With the same anesthesia condition, one of the twin fetus was chose to perform the intrauterine cardiac intervention surgery. The fetal heart beating rate was monitored, and blood samples of the fetus were taken to do the blood gas analysis and to detect the concentration of inflammatory cytokines (IL1, IL6, IL8, and TNFα). Results Two of the eight fetal lambs which was died in the operation because of pericardial tapenade. In the other six survived fetus, the PH was lower than after the surgery, and the concentrations of lactic acid, IL1, IL6, and IL8 are higher than after the surgery. There was no significant difference of PCO2,PO2 and TNFα between before and after the surgery. Conclusion The intrauterine cardiac intervention surgery can make the PH of fetal plasma lower and the concentrations of lactic acid and IL1, IL6, IL8 higher.
