Spontaneous Spinal Epidural Hematoma in an Adult Patient with Complex Congenital Heart Disease
We report the case of a 27-year-old man who developed sudden upper back pain with no specific precipitant. Five days later, he visited our emergency department complaining of weakness in both lower limbs and dysuria. He had a history of intracardiac repair and a Blalock-Park procedure for an interrupted aortic arch and ventricular septal defect in infancy. Additionally, he had undergone an aortic root dilatation and aortic valve replacement at the age of 10 because of progression of aortic and supra-aortic stenosis and had received chronic anticoagulation and antiplatelet therapy with warfarin and aspirin, respectively. An...

Clinical Use of the Amplatzer Device in the Management of Intracardiac Defects: A Single-Center Experience
Int J Angiol DOI: 10.1055/s-0038-1626718Device therapy is a viable alternative to open heart surgery in the management of intracardiac defects. The Amplatzer septal occluder (ASO) is one such device that has been adapted to close a wide variety of cardiac defects with few complications and a high success rate. This is a retrospective review of all the patients who received the ASO between 2012 and 2016 at the University of Kentucky. In total, 169 patients underwent percutaneous closure of a septal defect with Amplatzer during the timeframe studied, and of those, 91% received the device for an atrial septal defect or patent...

Noninvasive quantification of left-to-right shunt by phase contrast magnetic resonance imaging in secundum atrial septal defect: the effects of breath holding and comparison with invasive oximetry
AbstractTo investigate the effect of breath-holding on left-to-right shunts in patients with a secundum atrial septal defect (ASD). Thirty-five consecutive patients with secundum ASDs underwent right heart catheterization and invasive oximetry. Phase-contrast magnetic resonance imaging (MRI) was performed for the main pulmonary artery and ascending aorta. All measurements were obtained during free breathing (FB) (quiet breathing; no breath-hold), expiratory breath-hold (EBH), and inspiratory breath-hold (IBH). Pulmonary circulation flow (Qp) and systemic circulation flow (Qs) were calculated by multiplying the heart rate b...

One-stop shop assessment for atrial septal defect closure using 256-slice coronary CT angiography
Conclusions256-slice CCTA allows measuring Qp/Qs and size of defects and rims in patients with secundum ASDs, accomplishing pretreatment evaluation non-invasively and comprehensively.Key Points• Quantification of left-to-right shunting can be performed reliably and accurately by CT.• The sizes of defects and rims can be measured accurately using 256-slice CT.• 256-slice CT permits pretreatment evaluation of ASD non-invasively and comprehensively.

HeartStitch touts new PFO closure method
Structural heart focused HeartStitch said today its NobleStitch EL device was used to repair 3 patients with patent forman ovale heart defects in Astana, Kazakhstan. A patent foramen ovale is a congenital heart disease in which hole in the heart that normally seals at birth remains open, and can lead to severe migraines, visual auras and stroke, the company said. The procedures were performed by Dr. Michael Mullen and guided by Anthony Nobles at the National Research Cardiac Surgery Center in Astana, according to the company. “We are gratified that our colleagues from abroad have brought this technology to Kazakhstan...

Amplatzer left atrial appendage occlusion: Single center 10‐year experience
ConclusionLAA closure may be a good alternative to oral anticoagulation. This hypothesis needs to be tested in a randomized clinical trial to ensure that all potential biases of this observational study are accounted for. © 2013 Wiley Periodicals, Inc.
