Impact on clinical outcomes from transcatheter closure of the Fontan fenestration: A systematic review and meta-analysis.

Background: Meta-analysis of the impact on clinical outcome from transcatheter closure of Fontan fenestration.

Methods: Cochrane, Embase, MEDLINE, and Open-Gray were searched. Parameters such as changes in oxygen saturation, cavo-pulmonary pressure, maximum heart rate during exercise, exercise duration, and oxygen saturation after fenestration closure were pooled and statistical analysis performed.

Systematic review of imaging tests to predict the development of rheumatoid arthritis in people with unclassified arthritis.

Objective: To estimate and compare the diagnostic accuracy of magnetic resonance imaging (MRI) and ultrasound, for the prediction of rheumatoid arthritis (RA) in unclassified arthritis (UA).

Methods: MEDLINE, Embase and BIOSIS were searched from 1987 to May 2019. Studies evaluating any imaging test in participants with UA were eligible.

Transposition With Unobstructed Right Aortic Arch and Bicuspid Aortic Valve.

In patients with transposition, a right aortic arch has rarely been reported among the associated malformations. When present, the arch has been obstructed because of the presence of aortic coarctation and/or arch hypoplasia. A bicuspid aortic valve is also very rare in the presence of transposition.

Tetralogy of Fallot With Right Aortic Arch and Retro-Aortic Innominate Vein.

Right aortic arch (RAA) and retro-aortic innominate vein are rare vascular anomalies. Diagnosis of these anatomical variations can be achieved using fetal echocardiography, post-natal echocardiography, and computed tomography scan. RAA can form a vascular ring when associated with other vascular anomalies which may compress the trachea and/or esophagus.
