BACKGROUND AND OBJECTIVES Initial experience with transcatheter closure of patent ductus arteriosus (PDA) using detachable coils and Amplatzer duct occluder devices is reported. We evaluated the outcome, complications, and influence of the learning curve, and also assessed the need of surgical backup for such interventional procedures. METHODS From(More)
We have previously shown that pentoxifylline (PTX) protects from vascular complications associated with insulin resistance (IR). Here, we investigated the protective effect of PTX against cardiac ischemia and dysfunction following experimental angina in IR. IR, along with its accompanying cardiac dysfunction, was induced in rats by a high-fructose (10% in(More)
The aim of the present study is to investigate the effect and potential mechanism of action of 6-gingerol on alterations of vascular reactivity in the isolated aorta from diabetic rats. Male Wistar rats were divided into two experimental groups, control and diabetics. Diabetes was induced by a single intraperitoneal injection of streptozotocin (50 mg(More)
The aim of the current study was to evaluate the possible protective effect of allopurinol (Allo) on experimentally induced insulin resistance (IR) and vascular complications. Rats were divided into four groups: control, IR, allopurinol-treated IR (IR-Allo), and allopurinol-treated control (Allo). IR was induced by adding fructose and high fat, high salt(More)
Mycotic aneurysm is an established condition first identified in 1885 by Sir William Osler. It is linked to malignant endocarditis. With prevalence of 0.7-2.6% of all cases of aortic aneurysms, it is associated with a significant rate of mortality and morbidity. Physicians should be highly cautious, as diagnosis and effective treatment for this condition(More)
OBJECTIVES To assess the impact of congenital heart diseases (CHDs) on bio-psychosocial aspects of the quality of life (QOL) of patients and their families. METHODS A cross-sectional study was carried out between May 2014 and August 2015, including children aged less than 16 years, and followed-up at King Abdulaziz University Hospital, Jeddah, Kingdom of(More)
OBJECTIVES To assess the safety and effectiveness of transthoracic echocardiography (TTE) in monitoring transcatheter closure of atrial septal defect (ASD), in comparison with conventional technique using transesophageal echocardiography (TEE).  Methods: A retrospective review of all cases of transcatheter closure of isolated ostium secundum ASDs operated(More)
CONTEXT Idiopathic dilated cardiomyopathy (IDCM) is a severe illness with high mortality in the pediatric population. AIMS To highlight our experience about clinical course and outcome of IDCM. SETTINGS AND DESIGN Patients' files were reviewed retrospectively for diagnosed cases of IDCM in the pediatric cardiology unit of King Abdul Aziz University(More)
This paper argues that medical residents who do most of the hard work in big hospitals and medical colleges are overworked. A hierarchical organizational structure, staffing patterns, and fear of failure in examinations leads to overwork among residents going unreported. This can lead to poor academic performance and research work. Gaps in communication(More)
