Predicting the Need for Neoaortic Arch Intervention in Infants with Hypoplastic Left Heart Syndrome Through the Glenn Procedure.

Neoaortic recoarctation is present in up to over one-third of patients having undergone the Norwood procedure for hypoplastic left heart syndrome. Some of these patients will require reintervention by catheterization or surgery through the time of the Glenn procedure. Echocardiography and catheterization are often utilized in this period to assess hemodynamics although no specific criteria have been identified to predict whether and when neoaortic arch reintervention will be needed.

Comparison of Contrast Volume, Radiation Dose, Fluoroscopy Time, and Procedure Time in Previously Published Studies of Rotational Versus Conventional Coronary Angiography.

Conventional coronary angiography (CA) with static imaging is limited by the ability to properly select the optimal acquisition angle, vessel foreshortening, and significant radiation exposure. Rotational coronary angiography (RA) acquires coronary images in a multitude of viewing angles during a single injection by means of a moving gantry that rapidly completes a predefined arc. This study compares procedural characteristics of CA and RA.

Reversible brainstem edema due to hypertensive encephalopathy in an 8-year-old girl.

The authors report an 8-year-old girl with refractory status epilepticus due to hypertensive encephalopathy, secondary to end-stage renal disease. Brain magnetic resonance imaging (MRI) in the acute phase showed striking hyperintensities in the brain stem and medial thalamus along with subtle cortical lesions. After successful control of hypertensive crisis and status epilepticus, the patient recovered to her baseline.
