Acute myocardial infarction can culminate in sudden cardiac death due to cardiogenic shock and ventricular fibrillation, and also rarely due to cardiac rupture. We present a case of post-infarction myocardial rupture after thrombolytic therapy diagnosed with transthoracic echocardiography and treated with direct closure and coronary artery bypass grafting.
急性心肌梗死可因心源性休克和心室颤动而导致心源性猝死,也很少因心脏破裂而导致。我们报告一例经胸超声心动图诊断为心肌梗死后溶栓治疗后心肌破裂,并直接关闭和冠状动脉旁路移植术治疗。

Background: Coronary artery disease (CAD) is prevalent but very difficult to diagnose in hemodialysis (HD) patients compared with nonuremic individuals. Objectives: The aim of this study was to detect undiagnosed ischemic heart disease (IHD) using dipyridamole myocardial perfusion imaging (MPI) in HD patients. Patients and Methods: In this cross-sectional descriptive study, HD patients who met the inclusion criteria were selected. Demographic, clinical, and paraclinical data were obtained via interviews and medical records. Bedside electrocardiography, resting echocardiography, and nuclear MPI with dipyridamole were done. The data were analyzed using descriptive statistical methods for detecting the prevalence of undiagnosed IHD in the HD patients. The chi-square test and the independent t-test were used to identify the high-risk HD patients. Results: Sixty-nine HD patients were studied using dipyridamole MPI with Tc 99 m sestamibi. The mean age, body mass index, and mean duration of HD were 52.1 ± 13.8 years, 21.23 ± 4.79 kg/m2, and 48.2 ± 34.9 months, respectively. The patients were divided into two groups based on MPI: IHD-positive group (21.7%) and IHD-negative group (78.3%). IHD was more prevalent in the patients with diabetes mellitus, hypertension, positive family history of CAD, low HD adequacy index (Kt/V < 1.2), left ventricular hypertrophy, high intact parathyroid hormone levels, electrocardiographic abnormalities, and low ferritin levels. A statistically significant correlation was also detected between IHD and aging (P < 0.05). Conclusions: The prevalence of undiagnosed IHD in the HD patients was considerable. We, therefore, suggest that IHD be assessed in HD patients, especially those at high risk due to positive family history of CAD, hypertension, left ventricular hypertrophy, diabetes mellitus, Kt/V < 1.2, low ferritin levels, and high levels of intact parathyroid hormone.
背景:与非尿毒症患者相比,冠状动脉疾病(CAD)在血液透析(HD)患者中很普遍,但很难诊断。目的:本研究的目的是利用双嘧达莫心肌灌注显像(MPI)检测HD患者未确诊的缺血性心脏病(IHD)。患者和方法:在这项横断面描述性研究中,选择符合纳入标准的HD患者。通过访谈和医疗记录获得人口统计学、临床和临床旁数据。行床边心电图、静息超声心动图和核MPI双嘧达莫。使用描述性统计方法对数据进行分析,以检测HD患者中未确诊的IHD患病率。采用卡方检验和独立t检验鉴定高危HD患者。结果:69例HD患者采用双嘧达莫MPI联合Tc 99m sestamibi进行研究。平均年龄52.1±13.8年,体重指数21.23±4.79 kg/m2,平均病程48.2±34.9个月。根据MPI水平将患者分为ihd阳性组(21.7%)和ihd阴性组(78.3%)。糖尿病、高血压、冠心病家族史阳性、HD充分性指数低(Kt/V < 1.2)、左室肥厚、完整甲状旁腺激素水平高、心电图异常、铁蛋白水平低的患者易发生IHD。IHD与年龄也有统计学意义(P < 0.05)。结论:HD患者中未确诊的IHD患病率相当高。因此,我们建议对HD患者进行IHD评估,特别是那些有CAD阳性家族史、高血压、左心室肥厚、糖尿病、Kt/V < 1.2、低铁蛋白水平和高水平完整甲状旁腺激素的高危患者。

Background: β-thalassemia is an inherited disorder of β-globin biosynthesis. Dysfunction in hemoglobin chain production, ineffective erythropoiesis, and hemolysis occur in β-thalassemia. Pulmonary arterial hypertension (PAH) is increasingly detected in patients with β-thalassemia, and splenectomy which decreases the need for blood transfusion increases the pulmonary artery pressure (PAP). Objectives: This study aimed to assess the PAP in patients with β-thalassemia (male or female and major or intermedia) who had undergone splenectomy. Methods: A total of 137 patients suffering from β-thalassemia were evaluated during the study. All subjects were referred for cardiac evaluation. Clinical history, presence of cardiac symptoms, and previous splenectomy were noted. Standard M-mode, 2D, and Doppler echocardiographic examinations were performed for all subjects. Patients with a tricuspid regurgitant jet velocity (TRV) ≥2.5 m/s were considered at risk for PAH. Results: Average age of the patients was 21.15±6.68 years. No significant difference was observed in the PAP between the 2 groups of thalassemia major and intermedia and also the 2 sex groups. Indeed, 6.6% of the patients had an increased PAP. The significant finding of the study was that the patients who had had splenectomy were significantly at an increased risk of PAH (P = 0.046). Conclusions: The etiology of PAH in thalassemia is multifactorial such as inflammatory mediators. Also, the absence of the spleen plays an important role in developing a high TRV and PAH.
背景:β-地中海贫血是一种遗传性β-珠蛋白生物合成障碍。β-地中海贫血发生血红蛋白链生成功能障碍、红细胞生成功能低下和溶血。肺动脉高压(PAH)在β-地中海贫血患者中越来越多地被发现,脾切除术减少了输血需求,增加了肺动脉压(PAP)。目的:本研究旨在评估PAP在接受脾切除术的β-地中海贫血(男性或女性,重度或中度)患者中的应用。方法:对137例β-地中海贫血患者进行评估。所有受试者均接受心脏评估。记录了临床病史、心脏症状和既往脾切除术。对所有受试者进行标准m型、2D和多普勒超声心动图检查。三尖瓣反流射流速度(TRV)≥2.5 m/s的患者被认为有PAH的危险。结果:患者平均年龄21.15±6.68岁。重度、中度地中海贫血两组间、性别间PAP无显著性差异。事实上,6.6%的患者PAP增加。该研究的重要发现是脾切除术患者PAH的风险显著增加(P = 0.046)。结论:地中海贫血多环芳烃的病因是多因素的,如炎症介质。此外,脾脏的缺失在高TRV和PAH的发生中起着重要作用。

Background: Vibratory innocent murmur is the most common precordial innocent murmur in children. The mechanism of vibratory innocent murmur is still unclear. Objectives: The aim of this study is to learn the mechanism of the vibratory innocent murmur. Patients and Methods: The prospective cross-sectional study was conducted using 32 children who had the vibratory innocent murmur (cases) in Chiang Mai University Hospital and 27 normal healthy children (controls). Two-dimension, Doppler, and tissue Doppler echocardiography were performed on each subject to examine the difference between cases and controls. Results: The left ventricular false tendon was present in 84% of cases and 22% of controls (P < 0.001). Left ventricular outflow tract velocity was significantly higher in cases than in controls (P < 0.001). Early diastolic myocardial velocity at the base of the interventricular septum was lower in cases with false tendon than those without false tendon (P = 0.048). No significant difference was found regarding ascending aorta diameter, cardiac output and ejection fraction between the two groups. Left ventricular diastolic function was normal in all cases and controls. Conclusions: The vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. The presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. Normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory innocent murmur.
背景:振动性无害杂音是儿童最常见的心前无害杂音。振动性无害杂音的发生机制尚不清楚。目的:本研究的目的是了解振动性无害杂音的发生机制。患者和方法:采用前瞻性横断面研究,选取清迈大学医院的32例无性振动性杂音患儿(病例)和27例正常健康儿童(对照)。对每个受试者进行二维、多普勒和组织多普勒超声心动图检查,以检查病例与对照组之间的差异。结果:84%的病例和22%的对照组存在左心室假肌腱(P < 0.001)。病例左心室流出道流速显著高于对照组(P < 0.001)。有假肌腱组较无假肌腱组舒张早期室间隔基底部心肌流速低(P = 0.048)。两组升主动脉直径、心排血量、射血分数无显著差异。所有病例和对照组左室舒张功能正常。结论:单纯的振动性杂音与左心室假腱的存在和左心室流出道流速增高有关。左心室假肌腱的存在与早期舒张期心肌速度降低有一定的相关性。正常的左心室收缩和舒张功能可作为一种保证,以振动无害杂音。

Background: Tissue Doppler is a promising method that allows the measurement of time of systolic and diastolic tissue velocities. Ventricular dyssynchrony was assessed in patients with heart failure. In sub-Saharan Africa, very few studies have focused on ventricular dyssynchrony in healthy subjects. Objectives: The purpose of this study was to measure time-to-peak of systolic and diastolic velocities of different segments of left ventricle and apply ventricular dyssynchrony markers to healthy black African subjects. Patients and Methods: Fifty healthy black African were enrolled consecutively over a period of 3 months. Time-to-peak systolic velocities (TS) and Time-to-peak early diastolic velocities (TE) were measured at the four basal segments of left ventricle. Five dyssynchrony markers were assessed: difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity, time between septal time-to-peak systolic velocity and lateral time-to peak systolic velocity, standard deviation of time-to-peak systolic velocity of the four basal segments, difference between maximal time-to-peak early diastolic velocity and minimal time-to-peak early diastolic velocity, and standard deviation of time-to-peak early diastolic velocity of the four basal segments. Results: The frequency of some dyssynchrony markers was similar to that of other studies. The difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity was correlated with age and was higher among women. The prevalence of diastolic dyssynchrony was higher in black African subjects. Conclusions: Large-scale studies on the healthy black African population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences.
背景:组织多普勒是一种很有前途的方法,可以测量组织收缩和舒张速度的时间。在心力衰竭患者中评估心室非同步化运动。在撒哈拉以南非洲,很少有研究关注健康人的心室非同步化。目的:本研究的目的是测量左心室不同节段的收缩和舒张速度的峰值时间,并将心室非同步化标志物应用于健康的非洲黑人受试者。患者和方法:50名健康的非洲黑人连续入组3个月。测定左心室基底节段收缩期至峰值速度(TS)和早期舒张期至峰值速度(TE)。评估了五种非同步性指标:最大收缩期至峰值速度与最小收缩期至峰值速度之差、室间隔收缩期至峰值速度与侧侧收缩期至峰值速度之差、四个基底节段收缩期至峰值速度的标准差、最大舒张期至峰值速度与最小舒张期至峰值速度之差、四个基底节段舒张期至峰值速度的标准差。结果:部分非同步运动标志物出现频率与其他研究相似。最大收缩期至峰值速度和最小收缩期至峰值速度之间的差异与年龄相关,女性的差异更大。舒张不同步的患病率在非洲黑人受试者中较高。结论:对健康非洲黑人人群的大规模研究可以评估舒张非同步化与种族差异相关的心肌功能变化之间的关系。

Introduction: The term hydropneumopericardium describes the simultaneous accumulation of fluid and gas in the pericardial sac. This condition is mostly caused by primary infiltrative lesions from the adjacent organs, pericardial infections, or trauma and is a very rare situation, usually with favorable outcomes. Case Presentation: We describe a female patient with Lutembacher's syndrome complicated by cardiac tamponade. After surgical treatment, she developed iatrogenic hydropneumopericardium, which was treated conservatively. Conclusions: Iatrogenic hydropneumopericardium can be managed conservatively with supportive measures, and most of these cases resolve spontaneously if they are not large and destabilizing.
心包积液一词描述的是心包囊内同时积聚液体和气体。这种情况主要由邻近器官的原发性浸润性病变、心包感染或创伤引起,是一种非常罕见的情况,通常有良好的结果。病例介绍:我们描述了一个女性患者与卢滕巴赫综合征合并心脏填塞。手术治疗后,患者出现医源性心包积液,经保守治疗。结论:医源性心包积液可通过支持措施保守治疗,如果积液不大且不稳定,大多数病例可自行消退。

Introduction: Coronary angiography can be complicated by some major complications such as stroke. Case Presentation: We describe a patient who presented with hemiparesia. He had undergone coronary angiography on his right and left coronary arteries as well as his left ventricle (LV) via the radial artery access 10 days earlier using a 6-French Tiger catheter. Transthoracic echocardiography showed a large (36 × 25 mm) inhomogeneous mobile mass attached to the apicoseptal LV segment. His serum protein S was low (60% [normal = 77 - 140%]), while his protein C was normal and lupus anticoagulant was negative. During hospitalization, he developed severe abdominal pain, for which mesenteric ischemia was diagnosed. First, he underwent surgery for the resection of the infarcted intestinal segments. Then cardiac surgery was done to remove the mass. The mass was diagnosed as a thrombus. After the surgery, the general condition of the patient deteriorated and blood culture showed acinetobacter septicemia. Finally, he died due to sepsis. A review of his coronary angiography revealed that after the contrast media had left the LV, there was still dye at the contact point between the tip of the catheter and the LV, which was compatible with the location of thrombus formation. Conclusions: Trauma induced by the tip of the catheter at the contact location with the LV wall in a patient with mild hypercoagulable state accounted for intracardiac thrombosis formation and its embolization to the brain and intestines.
导言:冠状动脉造影可并发一些主要并发症,如中风。病例介绍:我们描述了一个病人谁提出偏瘫。患者于10天前使用6-French Tiger导管经桡动脉通道行左、右冠状动脉及左心室冠状动脉造影。经胸超声心动图显示一个大的(36 × 25 mm)不均匀的可移动肿块附着在鼻中隔左段。血清蛋白S低(60%[正常= 77 - 140%]),蛋白C正常,狼疮抗凝血阴性。住院期间出现严重腹痛,诊断为肠系膜缺血。首先,他接受了切除梗死肠段的手术。然后进行心脏手术切除肿块。肿块被诊断为血栓。术后患者一般情况恶化,血培养显示不动杆菌败血症。最后,他死于败血症。复查其冠状动脉造影发现,造影剂离开左室后,导管尖端与左室接触处仍有染色,与血栓形成位置相符。结论:轻度高凝患者心内血栓形成及脑、肠栓塞的原因是导管尖端与左室壁接触部位的创伤。

Background: Velocity vector imaging (VVI) is a new echocardiography method to assess myocardial deformation in two dimensions. Objectives: In this study, we used VVI to evaluate left ventricular (LV) main torsional parameters in non-ischemic dilated cardiomyopathy (DCM) patients in compared with normal subjects. Patients and Methods: Twenty-six DCM patients and Twenty-four normal subjects were assessed. Echocardiographic images of the short axis apical and basal views of LV were processed by VVI software to measure peak rotation degrees and also peak rotation rates in systole. LV twist was well-defined as the net difference between apical and basal rotation values and also LV torsion was considered as LV twist divided by left ventricular diastolic longitudinal length. In addition, peak untwisting value and untwisting rate were measured in diastole too. Results: LV twist value (5.54 ± 1.94° in DCM VS. 11.5 ± 2.45° in control group) and also LV torsion (0.71 ± 0.28°/cm in DCM VS. 1.53 ± 0.42°/cm in control group) were significantly decreased in DCM patients compared with normal group (P < 0.001 for both); also, the twisting rate was notably lower in DCM vs. control (38.68 ± 14.43°/s in DCM vs. 75.88 ± 17.25°/s in control; P < 0.001) and also untwisting rate (36.28 ± 13.48°/s in DCM vs. -73.79 ± 24.45°/s in control; P < 0.001), However normalization of these times for systolic duration or LV length creates different values. Conclusions: LV twist, torsion and untwist and also rate of them are significantly impaired in DCM and this impairment is well-related to LV global systolic and diastolic dysfunction. VVI is a new noninvasive technique that can be used to evaluate LV torsional parameters.
背景:速度矢量成像(Velocity vector imaging, VVI)是一种新的二维超声心动图方法。目的:在本研究中,我们用VVI评价非缺血性扩张型心肌病(DCM)患者左心室(LV)的主要扭转参数,并与正常人进行比较。患者和方法:对26例DCM患者和24例正常人进行评估。利用VVI软件对左室短轴尖、基位超声心动图图像进行处理,测量左室收缩期的旋转尖峰度和旋转尖峰速率。左室扭转被定义为左室顶端和基底旋转值的净差,左室扭转被认为是左室扭转除以左室舒张纵向长度。此外,还测定了舒张期的最大解扭值和解扭速率。结果:DCM患者左室扭转值(DCM组为5.54±1.94°,对照组为11.5±2.45°)和左室扭转值(DCM组为0.71±0.28°/cm,对照组为1.53±0.42°/cm)均显著低于正常组(P < 0.001);DCM组扭转速度明显低于对照组(38.68±14.43°/s), DCM组扭转速度低于对照组(75.88±17.25°/s);P < 0.001)和解扭速率(DCM组为36.28±13.48°/s,对照组为-73.79±24.45°/s;P < 0.001),然而,这些时间的收缩期或左室长度的正常化产生不同的值。结论:DCM患者左室扭转、扭转、解扭及扭转率明显受损,且与左室整体收缩舒张功能障碍密切相关。VVI是一种新的无创技术,可用于评估左室扭转参数。

Background: In patients with advanced heart failure, significant improvement in pharmacological and non-pharmacological treatment strategies has conferred better survival rates and quality of life. Objectives: This is a report on echocardiographic findings in heart transplantation (HTx) patients in their first 5 postoperative months. Patients and Methods: Twenty patients undergoing HTx between September 2009 and July 2010 whose clinical and echocardiographic findings had been registered monthly for 5 months after HTx were enrolled. Results: Eleven males and five females at a mean age of 33 years [range = 17-58 years] were enrolled in the study. The mean of the left ventricular ejection fraction (LVEF) was 52 ± 8.2 % and 58 ± 2.5 % on the first day and at 5 months after HTx, respectively. There was no LV enlargement at 5 months' follow-up. The right ventricle (RV) was mildly enlarged, but the reduced baseline RV function showed improvement at the 5th postoperative month (mean TAPSE was 11.7 ± 3.3 mm on the first post-HTx day versus 17.2 ± 6.3 mm after 5 months; P < 0.005). The pulmonary arterial pressure was slightly elevated at baseline, and it showed no significant decrease 5 months after HTx. More than 90% of the cases showed only mild tricuspid regurgitation at 5 months' follow-up. The tissue Doppler imaging-derived velocities of the medial and lateral mitral annuli and the tricuspid annulus demonstrated a gradual increment during the follow-up and reached their highest value at 5 months' follow-up. Conclusions: The cardiac grafts at 5 months' post-HTx follow-up were characterized by normal LV dimensions and EF. Also, RV dysfunction and tricuspid regurgitation were frequent findings, but they were not associated with the clinical signs of congestive heart failure, morbidity, and mortality in the majority of our patients.
背景:在晚期心力衰竭患者中,药物和非药物治疗策略的显著改善赋予了更好的生存率和生活质量。目的:报告心脏移植(HTx)患者术后5个月的超声心动图表现。患者与方法:入选2009年9月至2010年7月期间接受HTx治疗的20例患者,这些患者在HTx治疗后5个月内每月登记一次临床和超声心动图表现。结果:11名男性和5名女性被纳入研究,平均年龄33岁[范围= 17-58岁]。HTx术后第1天和5个月左室射血分数(LVEF)平均值分别为52±8.2%和58±2.5%。随访5个月未见左室扩大。右心室(RV)轻度增大,但减少的基线RV功能在术后第5个月有所改善(htx术后第一天的平均TAPSE为11.7±3.3 mm, 5个月后为17.2±6.3 mm;P < 0.005)。肺动脉压在基线时略有升高,HTx后5个月无明显下降。超过90%的病例在随访5个月时仅出现轻度三尖瓣反流。二尖瓣内、外侧环和三尖瓣环的组织多普勒成像速度在随访期间逐渐增加,并在随访5个月时达到最高值。结论:经htx术后5个月随访,心脏移植物左室尺寸和心功能正常。此外,右心室功能障碍和三尖瓣反流是常见的发现,但在我们的大多数患者中,它们与充血性心力衰竭的临床症状、发病率和死亡率无关。
