The treatment of chronic total occlusions is complex and associated with several risks and problems. Among therapeutic options including bypass surgery and medical therapy PCI represents an important strategy. PCI with stents, however, has limitations in such lesions due to characteristics like lesion length, unknown reference diameter and delayed stent coverage. Drug coated balloons have shown promising properties to overcome some of those limitations: They promote positive vessel remodeling and have a minimal thrombosis rate. In a first multicenter study it has been shown that drug coated balloons in proper indications and applied with appropriate technique might become a new treatment option for patients with chronic total occlusions.
慢性全闭塞的治疗是复杂的,与几个风险和问题有关。在包括搭桥手术和药物治疗在内的治疗选择中,PCI是一种重要的策略。然而,由于病变长度、参考直径未知和支架覆盖延迟等特点,PCI在此类病变中存在局限性。药物涂层气球已经显示出克服这些限制的前景:它们促进血管重构,并且具有最小的血栓率。第一项多中心研究表明,药物包被球囊在适当的适应症和应用适当的技术可能成为慢性全闭塞患者的一种新的治疗选择。

Cerebrovascular disease (CVD) accounts for the major cause of morbidity and mortality in industrialized countries. However, effects of high-dose simvastatin therapy on patients with acute cerebral infarction still unclear. In this study, the clinical efficacy of high-dose simvastatin on patients with cerebral infarction was investigated. A total of 180 patients with acute cerebral infarction were randomized divided into control group (n=60), high-dose simvastatin (HDS) group (n=60) and low-dose simvastatin (LDS) group (n=60). Control group, HDS group and LDS group received conventional treatment, conventional treatment together with simvastatin 80 mg/d and conventional treatment as well as simvastatin 40 mg/d respectively for 3 months. Biochemical indices, neurological deficit and plaque thickness and volume were assessed and recorded after treatment. After simvastatin treatment, the plasma levels of Triglyceride, Total cholesterol, Low-density lipoprotein were significantly decreased in HDS group and LDS group, and HDS were significantly increased in HDS group and LDS group. Also, simvastatin decreased levels of IL-6 and TNF-α, two major inflammatory factors in plasma. Furthermore, improved neurological deficit were found in simvastatin treatment groups. In addition, simvastatin treatment also improved plaque states include plaque thickness and volume in HDS group and LDS group. Therefore, simvastatin could improve acute cerebral infarction and high-dose of simvastatin treatment was better than low -dose of simvastatin treatment.
脑血管病(CVD)是工业化国家发病率和死亡率的主要原因。然而,大剂量辛伐他汀治疗急性脑梗死的效果尚不清楚。本研究探讨大剂量辛伐他汀治疗脑梗死患者的临床疗效。180例急性脑梗死患者随机分为对照组(n=60)、高剂量辛伐他汀组(n=60)和低剂量辛伐他汀组(n=60)。对照组、HDS组、LDS组分别给予常规治疗、常规治疗联合辛伐他汀80 mg/d、常规治疗联合辛伐他汀40 mg/d,疗程3个月。治疗后观察生化指标、神经功能缺损、斑块厚度和体积。辛伐他汀治疗后,HDS组和LDS组血浆甘油三酯、总胆固醇、低密度脂蛋白水平均显著降低,HDS组和LDS组血浆HDS水平均显著升高。此外,辛伐他汀降低血浆中两种主要炎症因子IL-6和TNF-α的水平。此外,辛伐他汀治疗组的神经功能缺损得到改善。此外,辛伐他汀治疗还改善了HDS组和LDS组的斑块状态,包括斑块厚度和体积。因此,辛伐他汀可改善急性脑梗死,且高剂量辛伐他汀治疗优于低剂量辛伐他汀治疗。

Significant unprotected left main coronary artery (ULMCA) disease occurs in 5-7% of patients undergoing coronary angiography [1,2] and patients with ULMCA disease treated medically have a three years mortality rate of 50% [3,4]. Advances in percutaneous intervention techniques and stent technology have allowed evolution of the role of percutaneous coronary intervention (PCI) for left main disease. Left main angioplasty is usually preferred through femoral route because of the larger diameter of the vessel and ease of maneuverability. In recent studies radial route has also been used consistently with better results. Left main coronary angioplasty through ulnar artery route is unheard off. In this case report ulnar access has been used to opine that it is also an alternative, safe, feasible and an additive access to femoral route. Case
在接受冠状动脉造影的患者中,有5-7%的患者出现明显的无保护的左主干冠状动脉(ULMCA)病变[1,2],经医学治疗的ULMCA病变患者3年死亡率为50%[3,4]。经皮介入技术和支架技术的进步使得经皮冠状动脉介入治疗(PCI)在左主干疾病中的作用得以演变。由于左主干血管成形术的血管直径较大且易于操作,因此通常首选经股动脉行左主干血管成形术。在最近的研究中,径向路径也一直使用,效果较好。通过尺动脉的左主干冠状动脉成形术闻所未闻。在本病例中,尺骨入路被认为是一种安全、可行的替代股骨入路。情况下

Catheter-directed angiography remains the gold standard both for diagnosis and treatment of a coronary artery anomaly (CAA). CAA intervention continues to remains a complicated task even in the hands of experienced operators. The greatest challenges faced in the management of CAAs are delays in identification and difficulty engaging the anomalous coronary artery. Operator experience in promptly identifying the anomaly and selection of the appropriate catheter is critical for successful CAA intervention. We discuss a series of cases where CAAs were encountered during angiography and review the diverse technical difficulties faced by operators during interventions of these congenital anomalies.
导管引导血管造影仍然是诊断和治疗冠状动脉异常(CAA)的金标准。即使在经验丰富的作业者手中,CAA干预仍然是一项复杂的任务。CAAs治疗面临的最大挑战是识别延迟和难以处理异常冠状动脉。操作人员在及时识别异常和选择合适导管方面的经验对于成功的CAA介入至关重要。我们讨论了一系列在血管造影中遇到CAAs的病例,并回顾了手术人员在干预这些先天性异常时面临的各种技术困难。

We report a case of primary coronary angioplasty of left coronary artery through right upper ulnar access with acute lusoria angle due to aberrant right subclavian artery. Although it is very tedious and challenging job to deploy stent in left coronary artery by upper arm access in Arteria lusoria. Hence we propose that PCI is feasible in a case of arteria lusoria by upper right arm access if done with great experience and skill.
我们报告一例因右锁骨下动脉异常而经右上尺路行左冠状动脉血管成形术的病例。尽管在左冠状动脉内通过上臂通道置入支架是一项非常繁琐和具有挑战性的工作。因此,我们认为,如果经验丰富,技术熟练,在右臂上侧入路的彩色动脉行PCI是可行的。

Cardiovascular disease is a major health risk since past decade. Surgical treatment for major heart diseases has been one of the major challenges since years. Cardiac valves are synthetic or bio prosthetic ones. Mechanical valves are long durable but highly thrombogenic and undergo calcification at higher rates demanding permanent anticoagulation, which increases the risk of bleeding. Biomaterial scaffolds are used in surgical replacements but only after decellularization and processing. Decellularization makes tissue less antigenic; reduce inflammatory response and less tissue degeneration. In this work two decellularization protocols are tried on bovine pericardium (BP) to find out the effect of each of them on the scaffold's integrity. BP undergone protocol 1(0.25% Trypsin-EDTA, TritonX-100, Deoxycholic acid, Peracetic acid/Ethanol) treatment was seen to have highly distorted and damaged collagen matrix. Decellularization with protocol 2 (Deoxycholic acid, DNase, RNase, Ethanol) resulted in a completely decellularised bovine pericardium. The extracellular matrix was intact as native one with collagen bundles. This will help cell attachment to the decellularised matrix.
近十年来,心血管疾病是一个主要的健康风险。多年来,主要心脏病的手术治疗一直是主要挑战之一。心脏瓣膜是人工合成或生物假体。机械瓣膜经久耐用,但极易形成血栓,并且需要永久性抗凝治疗,这增加了出血的风险。生物材料支架用于外科手术置换,但必须经过脱细胞和处理。脱细胞使组织抗原性降低;减少炎症反应,减少组织变性。本文在牛心包(BP)上试验了两种脱细胞方案,以了解每种脱细胞方案对支架完整性的影响。BP经过方案1(0.25%胰蛋白酶- edta, TritonX-100,脱氧胆酸,过氧乙酸/乙醇)治疗,胶原基质高度扭曲和受损。方案2(脱氧胆酸,脱氧核糖核酸酶,核糖核酸酶,乙醇)脱细胞导致牛心包完全脱细胞。细胞外基质与天然基质一样完整,有胶原束。这将有助于细胞附着到去细胞化的基质上。

Ventricular septal rupture is still a rare but often fatal complication of acute myocardial infarction. Emergent surgical closure of postinfarction ventricular septal rupture irrespective of the clinical status has been the standard treatment so far. A percutaneous approach using an occluder device is a less invasive option and allows immediate complete closure after initial hemodynamic stabilization. Furthermore immediate reduction of the left-to-right shunt, even if the ventricular septal rupture is not completely closed, may stabilize the patient enough to function as a bridge to surgery. We present two similar cases of patients which highlight the multiple features of acute myocardial infarction- related ventricular septal rupture treated with two alternative techniques.
室间隔破裂仍然是一种罕见但往往致命的急性心肌梗死并发症。急性脑梗死后室间隔破裂,不论临床情况如何,急诊手术缝合是目前的标准治疗方法。使用闭塞装置的经皮入路是一种侵入性较小的选择,并且可以在初始血流动力学稳定后立即完全关闭。此外,即使室间隔破裂未完全关闭,立即减少左向右分流也可以使患者足够稳定,作为手术的桥梁。我们提出了两个类似的病例,突出了急性心肌梗死相关室间隔破裂的多重特征,采用两种替代技术治疗。

Purpose: The present study looked at gender difference in oxygen delivery-extraction at maximal oxygen uptake in healthy adolescents. Methods: 36 adolescent males (14.9 ± 1.1 years) and 33 adolescent females (15.0 ± 1.1 years) underwent a maximal oxygen uptake test and a two dimensional direct m-mode echocardiography performed on a bicycle ergometry. Arteriovenous oxygen difference was defined by utilizing the Fick equation. Results: At rest, males compared to females had significantly (p<0.05) higher oxygen extraction (38.8 ± 1.4 and 31.8 ± 1.2 mL.kg-1 .min-1 respectively), systolic blood pressure, and mean arterial blood pressure. At peak exercise test, males compared to females demonstrated significant (P<0.05) higher values for cardiac output (16.6 ± 0.7 and 15.4 ± 0.6 L∙min-1 respectively), stroke volume (83.9 ± 5.1 and 78.5 ± 4.6 mL respectively), oxygen uptake (47.3 ± 3.7 and 39.6 ± 1.1 mL∙kg-1∙min-1, respectivel y), while oxygen extraction was significantly higher in females compared to males (123.6 ± 7.6 and 115.5 ± 5.4 mL∙L-1 respectively). Conclusions: This study suggests that normal adolescents; male and females respond to the maximal oxygen uptake test by increased their left ventricular systolic function, however, it was less augmented in the females due to gender and energy metabolism differences. Consequently, females increased their oxygen extraction more than the males as a compensation for the lower cardiac output and hence, lower oxygen delivery.
目的:本研究观察健康青少年最大摄氧量时的氧输送-提取的性别差异。方法:36例青少年男性(14.9±1.1岁)和33例青少年女性(15.0±1.1岁)在自行车上进行最大摄氧量试验和二维直接m型超声心动图。动静脉氧差用菲克方程定义。结果:静息时,男性吸氧量(38.8±1.4 mL.kg-1 .min-1)、收缩压、平均动脉压显著高于女性(p<0.05)。在运动峰值试验中,男性的心输出量(分别为16.6±0.7和15.4±0.6 L∙min-1)、搏气量(分别为83.9±5.1和78.5±4.6 mL)、摄氧量(分别为47.3±3.7和39.6±1.1 mL∙kg-1∙min-1)显著高于女性(分别为123.6±7.6和115.5±5.4 mL∙L-1),而吸氧量(分别为123.6±7.6和115.5±5.4 mL)显著高于男性(P<0.05)。结论:本研究提示正常青少年;男性和女性对最大摄氧量试验的反应是增加左心室收缩功能,但由于性别和能量代谢的差异,女性左心室收缩功能的增强程度较低。因此,雌性比雄性更多地增加吸氧量,以补偿较低的心输出量,从而减少氧气输送。

Consequently, females increased their oxygen extraction more than the \u0000 males as a compensation for the lower cardiac output and hence, lower oxygen delivery.","PeriodicalId":15504,"journal":{"name":"Journal of Clinical and Experimental Cardiology","volume":"9 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87960704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Since its introduction, percutaneous aspiration embolectomy (PAE) has become a well-known, widely accepted and frequently applied technique for the treatment of acute arterial embolic infrainguinal vascular occlusion in lower limb ischemia.Purpose: To evaluate the technical and clinical success of sole percutaneous aspiration embolectomy (PAE) for the treatment of acute arterial embolic infrainguinal vascular occlusion.Material and Methods: During a period of 7 years, 50 patients (24 fermale, 48%) with a mean age of 73 (range 53–95) years were identified in whom 54 cases of PAE were performed for the treatment of arterial embolic infrainguinal vascular occlusion. Primary technical success was defined as residual stenosis of <50% in diameter after sole PAE, secondary technical success was defined as residual stenosis of <50% in diameter after PAE and additional percutaneous transluminal angioplasty (PTA) and/or stenting. Clinical outcome parameters (e.g. need for further intervention and/or amputation) were evaluated for the 30-day postinterventional period.Results: The primary technical success rate was 85% (46 of 54 cases). The secondary technical success rate was 96% (52 of 54 cases). Clinical outcome data were achievable in 50 of the 54 cases (93%). In 43 of the 50 patients (86%) there was no need for further intervention within the 30-day postinterventional period. In summary, during this 30-day postinterventional period after PAE amputation was carried out or death occurred in 5 of 50 patients (10%).Conclusion: Minimally invasive PAE is an effective and safe technique for the treatment of acute arterial embolic infrainguinal vascular occlusion.
背景:经皮穿刺栓子切除术(percutaneous穿刺栓子切除术,PAE)自问世以来,已成为治疗下肢缺血急性动脉栓塞性腹股沟下血管闭塞的一种众所周知、被广泛接受和经常应用的技术。目的:评价单纯经皮穿刺栓子切除术(PAE)治疗急性动脉栓塞性腹股沟下血管闭塞的技术和临床效果。材料与方法:在7年的时间里,我们发现50例患者(女性24例,48%),平均年龄73岁(53-95岁),其中54例采用PAE治疗动脉栓塞性腹股沟下血管闭塞。初级技术成功被定义为单独PAE后残余狭窄直径小于50%,二级技术成功被定义为PAE和额外的经皮腔内血管成形术(PTA)和/或支架置入术后残余狭窄直径小于50%。临床结果参数(例如,是否需要进一步干预和/或截肢)在干预后30天进行评估。结果:54例患者中46例首次手术成功率85%。二次技术成功率为96%(54例中52例)。54例患者中有50例(93%)获得临床结果数据。50例患者中有43例(86%)在干预后30天内无需进一步干预。总之,在介入后的30天内,50例患者中有5例(10%)发生了PAE截肢或死亡。结论:微创PAE是治疗急性动脉栓塞性腹股沟下血管闭塞的一种安全有效的技术。

In 1908, McMurrich described the presence of strictures in the common iliac vein that were believed to be responsible for the increased incidence of left leg deep-vein thrombosis (DVT). This syndrome would eventually become known as iliac vein compression syndrome or May-Thurner Syndrome (MTS). Left iliac vein compression from the contralateral right common iliac artery, against the posterior fifth lumbar vertebral body, is estimated to comprise 49% to 62% of cases of left lower extremity disease.
1908年,McMurrich描述了髂总静脉狭窄的存在,这被认为是左腿深静脉血栓(DVT)发生率增加的原因。这种综合征最终被称为髂静脉压迫综合征或May-Thurner综合征(MTS)。对侧右侧髂总动脉压迫左侧髂静脉,压迫第五腰椎后椎体,估计占左下肢疾病病例的49%至62%。
