Boomerang-shaped heart in isolated dextroversion.

The syndrome of dextroversion of the heart.

On the basis of 3 personal cases and 119 additional cases collected from the literature the difference between dextroversion and mirror-image dextrocardia is outlined. It is concluded that dextroversion is a part of an exceedingly primitive arrest in development that frequently includes other thoracic and abdominal organs as well as intracardiac structures. The defect is altogether different in...

Boomerang shaped aggregates from a histidine surfactant

Is it dextrocardia or dextroversion?

1 of 2 DESCRIPTION A 69-year-old male, chronic smoker, presented with dyspnoea on exertion of 6 months duration. His clinical examination was unremarkable and his chest x-ray ( fi gure 1 ) showed cardiac silhouette to be predominantly on the right side of thoracic cavity, mimicking dextrocardia. As it is an apicolardotic posteroanterior view with rotation to right, the cardiac silhouette appear...

Unusual fan shaped ossification in a female fetus with radiological features of boomerang dysplasia.

We report on a female fetus of 24 weeks whose clinical and radiological findings were compatible with boomerang dysplasia (BD). However, histopathology was unusual with a lateral fan shaped diaphyseal ossification. This has never been described either in typical atelosteogenesis I (AT-I) or in BD. The purpose of this report is to find out if this condition is a separate lethal bone dysplasia or...

Negative P Waves in Lead I in Dextroversion: Differential Diagnosis from Mirror-Inage Dextrocardia

IN CONGENITAL dextrocardia the problem is frequently whether dextroversion or a mirror-image dextrocardia is present. In the former the atria preserve their usual relationship in the frontal plane but the left ventricle lies anterior to the right. In mirror-image dextrocardia there is atrial inversion and the right ventricle lies anterior to the left. The electrocardiographic findings are gener...
