Abstract

:In this paper, 64-slice spiral computed tomography (CT) retrospective electrocardiographic (ECG) gating technology was used to perform coronary CT angiography scans. The aorta and aortic pulmonary artery diameter were measured quantitatively in healthy people and patients with hypertension and cerebrovascular disease. Corresponding aortic pulmonary artery ratios were obtained through calculation, and the changes of aortic diameter, aortic pulmonary artery ratio, and aortic diameter difference between different cardiac phases, ages, sexes, and levels of hypertension were discussed. Through research, it can be concluded that 64-row spiral CT scan combined with ECG gating technology can accurately measure the dynamic changes of the aortic diameter with the cardiac cycle. At the same time, the aortic diameter measured by multidetector CT scan combined with ECG gating technology and the phase difference between different phases can objectively reflect the degree of arterial damage in patients with hypertension; therefore, early screening of aortic diseases in patients with hypertension can be performed. Diagnosis to detect abnormalities as early as possible and start treatment as early as possible to prevent the disease from progressing and even affecting other tissues and organs can also be obtained.

摘要

: 本文采用64层螺旋ct回顾性心电门控技术进行冠状动脉CT血管成像扫描。对健康人和高血压、脑血管病患者的主动脉和主动脉肺动脉直径进行定量测量。通过计算得到相应的主动脉肺动脉比率,并探讨不同心相、年龄、性别、高血压程度之间主动脉直径、主动脉肺动脉比率、主动脉直径差异的变化。通过研究可以得出结论: 64排螺旋ct扫描结合心电门控技术可以准确测量主动脉内径随心动周期的动态变化。同时,多排螺旋ct扫描结合心电门控技术测得的主动脉直径及不同时相间的相位差,可客观反映高血压患者动脉损害程度; 因此,可对高血压患者进行主动脉疾病的早期筛查。诊断,以尽早发现异常,尽早开始治疗,防止病情进展,甚至影响其他组织器官,也可获得

METHODS::We present the case of a 61-year-old woman with a large tumoral infiltration extending from the pelvis throughout the inferior vena cava inferior to the right atrium, protruding into the right ventricle and right ventricular outflow tract. She had been treated 10 years before for low-grade endometrial stromal sarcoma by hysterectomy and adnexectomy followed by hormone- and radio-therapy. Due to cancer recurrence, she underwent peritonectomy, appendectomy, and resection of terminal ileum.

METHODS:AIMS:Significant platelet activation after long stented coronary segments has been associated with periprocedural microvascular impairment and myonecrosis. In long lesions treated either with an everolimus-eluting bioresorbable vascular scaffold (BVS) or an everolimus-eluting stent (EES), we aimed to investigate (a) procedure-related microvascular impairment, and (b) the relationship of platelet activation with microvascular function and related myonecrosis. METHODS AND RESULTS:Patients (n=66) undergoing elective percutaneous coronary intervention (PCI) in long lesions were randomised 1:1 to either BVS or EES. The primary endpoint was the difference between groups in changes of pressure-derived corrected index of microvascular resistance (cIMR) after PCI. Periprocedural myonecrosis was assessed by high-sensitivity cardiac troponin T (hs-cTnT), platelet reactivity by high-sensitivity adenosine diphosphate (hs-ADP)-induced platelet reactivity with the Multiplate Analyzer. Post-dilatation was more frequent in the BVS group, with consequent longer procedure time. A significant difference was observed between the two groups in the primary endpoint of ΔcIMR (p=0.04). hs-ADP was not different between the groups at different time points. hs-cTnT significantly increased after PCI, without difference between the groups. CONCLUSIONS:In long lesions, BVS implantation is associated with significant acute reduction in IMR as compared with EES, with no significant interaction with platelet reactivity or periprocedural myonecrosis.

METHODS:BACKGROUND:Aortopulmonary window is an uncommon congenital heart disease, with untreated cases not surviving beyond childhood. However, very rarely it can present in adult patients with features of pulmonary hypertension. Clinically these patients cannot be differentiated from other more common conditions with left to right shunt. Transthoracic echocardiography if performed meticulously, can depict the defect in aortopulmonary septum. RESULTS:We report a case of large unrepaired aortopulmonary window in a 23 years old patient, diagnosed on transthoracic echocardiography.
