Late free atrial wall rupture after percutaneous atrial septal defect closure and transvenous pacemaker implantation

We report a remarkable case of right atrial rupture, 3 years after transcatheter closure of a secundum atrial septal defect, and 7 months after permanent transvenous two‐chamber pacemaker implantation. The etiology of the rupture remains unclear, but the presence of the two intracardiac devices is probably not coincidental. © 2008 Wiley‐Liss, Inc.     

Cardiac perforation and tamponade 3 months after transcatheter PFO closure by STARFlex device: A case report

Percutaneous Patent Foramen Ovale (PFO) closure after paradoxical embolism has become established as a safe, effective and validated procedure. The use of dedicated devices by experienced operators allows for low complication rates and good clinical results in the prevention of paradoxical embolism recurrence. This has led to a widespread use of the technique. However, late complications have been reported after the implantation of different types of devices. We report the first case of cardiac tamponade due to atrial wall erosion, which occurred three months after the implantation of a STARflex device (Nitinol Medical Technologies, Boston, Massachusetts, USA) in a 57 year‐old‐patient Transoesophageal echocardiographic images and surgical views of the perforation related to the device are presented. This report describes treatment of a late complication that arose following implantation of a STARflex device. © 2008 Wiley‐Liss, Inc.     

Age is not a predictor of patent foramen ovale with right-to-left shunt in patients with cerebral ischemic events

BACKGROUND: Patent foramen ovale (PFO) with or without atrial septal aneurysm (ASA) is highly associated with cerebral ischemic events in young patients. The prevalence of PFO and ASA in elderly patients with cerebral ischemic events is not well described. OBJECTIVE: Our study is to evaluate the frequencies of PFO with right-to-left shunt (RLS) and ASA in elderly patients and to determine whether age is a predictor of flow-reversed PFO with RLS in cerebral ischemic events. METHODS: A prospective registry for all consecutive patients with cerebral ischemic events who were evaluated by transesophageal echocardiography (TEE) for the detection of possible cardiac source of embolization was established and maintained in a university hospital. Patients' demographics including age, gender, ethnic origin, cerebrovascular risk factors, and all positive TEE data were collected from July 2000 to August 2001 for statistical analysis. A univariate and multivariate stepwise logistic regression analysis was performed. RESULTS: In older patients the prevalence of PFO with RLS, PFO, and ASA was 25/118 (20%), 28/118 (24%), and 38/118 (32%), respectively, as opposed to younger patients, in whom it was 35/119 (30%), 39/119 (33%), and 38/119 (32%), respectively. Older patients had higher frequencies of hypertension (59; 69%), CAD (25; 21%), and prior history of stroke (23; 20%) as opposed to younger patients. Younger age (<60 years), gender, smoking history, hypertension, hyperlipidemia, CAD, and prior history of stroke were not associated with higher prevalence of PFO with RLS. Patent foramen ovale was associated with ASA (P < 0.001) and LVH (P < 0.019) in patients with TIA and stroke. In multivariate analysis only ASA (P < 0.001) remained significant with PFO, with RLS controlling for age, gender, and LVH. CONCLUSIONS: PFO with RLS and ASA are frequently present in elderly stroke and/or TIA patients and age is not a predictor for PFO. Transesophageal echocardiography should be considered for all stroke and/or TIA patients irrespective of their age.     

超声心动图在卵圆孔通道血流受限合并心功能异常产前诊断中的应用价值

目的探讨超声心动图在单纯卵圆孔通道血流受限（FOCR）合并心功能异常胎儿产前诊断及预后评估中的应用价值。 方法回顾性选取2018年10月至2020年5月在河北生殖妇产医院检查,产前超声心动图诊断为单纯FOCR且心血管整体评分（CVPS）提示心功能异常的胎儿16例,分析其初诊、分娩前及出生后的超声心动图特征、CVPS及心功能变化,并随访其妊娠结局和预后。 结果14例表现为卵圆孔内径或卵圆孔通道有效分流口内径＜3 mm,2例表现为卵圆孔内径/房间隔总长度＜0.33。16例胎儿分娩前均表现为右心房与左心房横径比（RA/LA）、右心室与左心室横径比（RV/LV）、主肺动脉与升主动脉内径比（MPA/AAO）比值增大,且随孕龄增大而增大,卵圆孔通道分流流速（V-FO）＞40 cm/s。16例胎儿中,14例初诊FOCR时CVPS为8~9分,2例初诊未发现心功能异常,CVPS为10分。16例胎儿分娩前,11例表现为轻度心力衰竭,CVPS为8~9分;5例表现为中度心力衰竭,CVPS为6~7分。9例分娩前CVPS较初诊FOCR时减低。16例胎儿出生后,1例于新生儿期死亡;余15例均存活。存活患儿中13例复查超声心动图,心脏结构正常;1例分娩前CVPS为6分,出生后复查可疑心肌病;1例分娩前CVPS为8分,出生后复查不除外原发性肺动脉高压。 结论超声心动图在FOCR诊断及评估中具有重要价值;应用超声心动图进行CVPS评分可动态观测并评估胎儿心功能变化,对评估胎儿宫内情况及指导分娩时机具有重要意义。     

Orthodeoxia-platypnea due to intracardiac shunting relief with transcatheter double umbrella closure

The safety and efficacy of transcatheter clamshell occlusion of patent foramen ovale for relief of severe arterial desaturation and dyspnea in the upright position due to intracardiac shunting were examined in eight patients with excessive risk of surgical patent foramen ovale closure. All patients had successful reduction of intracardiac shunting with an immediate rise in oxygen saturation ?95% by implantation of a clamshell device on the atrial septum. Despite two early incidents of device embolization, retrieval and immediate re-implantation, and one patient with nonsustained atrial and ventricular arrhythmias, there were no adverse clinical sequelae. In follow-up evaluation transcatheter clamshell closure of patent foramen ovale has provided persistent relief from shuntrelated arterial desaturation and symptomatology in all living patients. © 1995 Wiley-Liss, Inc.     

Refractory hypoxemia in inferior myocardial infarction from right-to-left shunting through a patent foramen ovale: A case report and review of the literature

Right ventricular (RV) infarction is a well-recognized complication of some acute inferior myocardial infarctions. Recently, there have been numerous case reports of RV infarctions complicated by severe refractory hypoxemia secondary to right-to-left shunting through a patent foramen ovale. An additional case missed by transthoracic echocardiography and cardiac catheterization is reported and the English literature on the subject is reviewed.
