A new case of Myhre syndrome.

Myhre Syndrome is a rare condition associated with mental retardation, short stature, generalized muscle hypertrophy, cardiac defects and a distinct facial appearance. There have only been five reported cases and we now present a sixth, together with a review of the clinical features of this syndrome.

Assessment of the quality of neonatal echocardiographic images transmitted by ISDN telephone lines.

Objective: To assess the quality of echocardiographic images from neonates transmitted over Integrated Service Digital Network 2 (ISDN2) channels.

Design: Echocardiographic images were viewed live in real time either by a direct video link or by transmission over the commercial network, using one, two, or three ISDN2 channels. The order of the viewing formats was random and four observers marked each view for potential for provision of complete diagnostic information and quality.

Reduced heart rate variability following repair of tetralogy of Fallot.

Objective: To examine autonomic function as assessed by heart rate variability in patients 10 or more years after repair of tetralogy of Fallot, and to relate this to cardiac structure, function, and electrocardiographic indices.

Methods: Heart rate variability was measured by standard time domain techniques on a 24 hour Holter ECG in 28 patients, aged 12 to 34 years (mean 19.5), who had undergone repair of tetralogy of Fallot at least 10 years previously.

Outcomes of transposition of the great arteries in the ear of atrial inflow correction.

Objective: To examine long term morbidity and mortality following atrial inflow corrective procedures for transposition of the great arteries (TGA) and to investigate factors that influence morbidity and mortality.

Design: Retrospective cohort study from a single centre.

Setting: Cardiology and cardiothoracic surgical unit in a large tertiary referral centre.
