Dextrocardia, Situs Inversus, and Twinning

Situs inversus, asymmetry, and twinning.

THE relation of situs inversus to twinning has attracted much attention from experimental embryologists. Thus, Spemann and Ruud (1922) produced situs inversus by division of the amphibian egg, the twin derived from the right half frequently showing situs inversus. Komai (1938) observed situs inversus in the salmon, particularly in one partner of conjoined twins and relatively frequently in the ...

Dextrocardia and isolated laevocardia. II. Situs inversus and isolated dextrocardia.

Recently, we have reported 20 cases of isolated 1lvocardia (Campbell and Deuchar, 1965), and here we are describing 33 cases of dextrocardia with malformations of the heart. These are nearly always present when the heart is on the right side without inversion of the abdominal viscera (isolated dextrocardia), as they are with isolated levocardia: generally they produce a right-to-left shunt and ...

Dextrocardia and Situs inversus in a dog

Aim: The aim of this study was to report a case of dextrocardia with Situs inversus totalis. Case History and Observation: A nine-year-old male Cocker Spaniels dog was referred for cardiologic evaluation due to non-productive cough. Thoracic radiography and ultrasound examination showed the reversed position not only of the heart but also of the abdominal organs such as liver and gallbladder, s...

Coronary arteriography in situs inversus dextrocardia.

Sekctive coronary artedography by the Judkins' technique cao he readily accomplished in dextrocprdin. CinersdialCrspbs should be obtained in tbe mirror image obliquities for each coronary vessel and card&c cbamher. To avoid any potentid error of identitication and interpretation of the coronary vessels, films could he reviewed in revenre fashion, which would project the cardiac stnretwesasiftbe...
