Abstract

OBJECTIVE:We aim to evaluate the midterm effect of chronic apical right ventricular (RV) pacing on right and left ventricular (LV) function using different modalities of echocardiography including conventional echocardiography, tissue Doppler imaging and two-dimension speckle tracking echocardiography. METHODS:This case-control study enrolled 49 patients divided into two groups: a paced group and a nonpaced group. The paced group included 23 patients that underwent tetralogy of Fallot (TOF) repair and required permanent pacemaker insertion for postoperative complete heart block. The nonpaced group included 26 patients that had TOF repair at the same period. RESULTS:The median age for the paced and nonpaced groups was 6 and 8 years, respectively (P = .169). The follow-up duration after TOF surgical repair was 4 years for the paced patients and 5 years for nonpaced patients (P = .411). In the nonpaced group, the QRS duration increased and LV global longitudinal strain (GLS) decreased significantly with increasing duration after TOF repair, P value was .006 and .042, respectively. In the paced group, tricuspid annular systolic plane excursion (TAPSE) was significantly correlated with age (r = .578; P = .004) and duration following TOF correction (r = .724; P < .001). CONCLUSION:Chronic RV apical pacing in children after TOF repair was associated with better clinical status, preservation of RV systolic function, and prevention of progressive QRS prolongation. RV pacing was not associated with progressive deterioration of LV systolic function with increasing the time interval following TOF repair. Therefore, RV pacing can be beneficial in corrected TOF patients presenting with RV failure.

摘要

目的: 应用常规超声心动图、组织多普勒成像和二维斑点追踪技术评价慢性心尖右室起搏对右室功能的中期影响。 方法: 本病例对照研究纳入49例患者,分为两组: 起搏组和非起搏组。起搏组包括23例接受法洛四联症 (TOF) 修复术并因术后完全性心脏传导阻滞需要永久起搏器置入的患者。非起搏组包括同期进行TOF修复的26例患者。 结果: 起搏组和非起搏组的中位年龄分别为6岁和8岁 (p =.169)。TOF手术修复后的随访时间对于有节奏的患者为4年,对于无节奏的患者为5年 (p   =  .411)。在非起搏组中,随着TOF修复后持续时间的增加,QRS时限增加,LV整体纵向应变 (GLS) 显著降低,p值分别为.006和.042。在起搏组中,三尖瓣环收缩平面偏移 (TAPSE) 与年龄 (r   =  .578; P   =  .004) 和TOF校正后的持续时间 (r   =  .724; P  < .001) 显著相关。 结论: TOF修复后的儿童慢性RV心尖部起搏与更好的临床状态、保持RV收缩功能和预防进行性QRS延长有关。随着TOF修复后时间间隔的增加,RV起搏与LV收缩功能的进行性恶化无关。因此,RV起搏在呈现RV失败的校正的TOF患者中可能是有益的。

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.
