Long-term follow-up and sex differences in adults operated for tetralogy of Fallot.

Objective: Adults operated for tetralogy of Fallot (TOF) have high risk of ventricular arrhythmias (VA). QRS duration >180 ms is an established risk factor for VA. We aimed to investigate heart function, prevalence of arrhythmias and sex differences in patients with TOF at long-term follow-up.

Is experienced pregnancy in women with repaired tetralogy of Fallot related to diffuse myocardial fibrosis?

Objectives: To assess the impact of pregnancy on cardiac function and fibrosis by cardiovascular magnetic resonance (CMR) in patients with repaired Tetralogy of Fallot (rToF).

Background: CMR T1 mapping can assess diffuse myocardial fibrosis which is associated to adverse clinical outcomes. Right ventricular (RV) accelerated remodeling is reported in rToF women with experienced pregnancy.

Impact of pregnancy and risk factors for ventricular arrhythmias in women with tetralogy of Fallot.

Objective: Patients with tetralogy of Fallot (TOF) have high survival rates 30 years after surgical repair. Many patients experience pregnancy; however, the effects of pregnancy on the long-term cardiovascular outcome are not well known. We investigated the association of pregnancy and cardiac function with occurrence of ventricular arrhythmia (VA) in women with TOF.

An 8-year population description from a national treatment centre on lymphatic malformations.

Introduction: Lymphatic malformations are rare developmental non-malignant abnormalities that present as masses consisting of abnormal growth of fluid filled channels or spaces in the skin or deep tissue that result in abnormalities of lymphatic flow. They may cause symptoms like pain, recurrent lymphorrea, abnormal bone growth, and disturbance of bodily functions. They may also be a cosmetic problem.

Pulmonary valve replacement with a bovine pericardial valve: a five year follow-up study.

Objectives: From a population of 90 patients after pulmonary valve replacement with a biological valve (Carpentier-Edwards Perimount valve), 56 of 80 available patients were examined five years after surgery.

Background: Pulmonary valve replacement is needed in many patients with congenital heart disease. Homografts have limited availability and predictable degeneration, and mechanical valves require anticoagulation.

Right ventricular volumes assessed by echocardiographic three-dimensional knowledge-based reconstruction compared with magnetic resonance imaging in a clinical setting.

Objectives: A technique that uses two-dimensional images to create a knowledge-based, three-dimensional model was tested and compared to magnetic resonance imaging.

Background: Measurement of right ventricular volumes and function is important in the follow-up of patients after pulmonary valve replacement. Magnetic resonance imaging is the gold standard for volumetric assessment.

Radiographic follow-up of community-acquired pneumonia in children.

Aim: To evaluate the value of radiographic follow-up of community-acquired pneumonia in children who are previously healthy.

Methods: Patient records for the years 2003 and 2004 at the Ullevål University Hospital in Oslo were reviewed, and a total of 245 children were selected for the study. Radiographs were evaluated by two paediatric radiologists independently.

A prospective randomized comparison between two MRI studies of the small bowel in Crohn's disease, the oral contrast method and MR enteroclysis.

The aim was to compare bowel distension and diagnostic properties of magnetic resonance imaging of the small bowel with oral contrast (MRI per OS) with magnetic resonance enteroclysis (MRE). Forty patients with suspected Crohn's disease (CD) were examined with both MRI methods. MRI per OS was performed with a 6% mannitol solution and MRE with nasojejunal intubation and a polyethylenglycol solution.
