Pitx2 confers left morphological, molecular, and functional identity to the sinus venosus myocardium
In the first trimester the ductus venosus can be easily identified with color Doppler and a ductus venosus waveform can be obtained by pulsed Doppler. At 11-13 weeks the prevalence of abnormal a-wave in the ductus venosus is inversely related to fetal crown-rump length and maternal serum pregnancy-associated plasma protein-A (PAPP-A), increases with fetal nuchal translucency (NT) thickness and ...
PAES DE CARVALHO, ANTONIO, WALMOR CARLOS DE MELLO AND BRIAN F. HOFFMAN. Electrophysiological evidence for specialized Jiber types in rabbit atrium. Am. J. Physiol. I g6(3):483-488 I g59.-Intracellular microelectrodes have been used to study the site of origin and direction of spread of activity in the rabbit atrium. In this study a number of fiber groups have been found which possess specialize...
We acknowledge the letter from Murakami and colleagues about our article, “Bilateral Superior Venae Cavae With Crisscross Atrial Drainage.” In that article, we documented a rare thoracic systemic venous drainage anomaly in which a persistent left superior vena cava was seen draining into the right atrium (RA) via the coronary sinus and the right superior vena cava (RSVC) draining into the left ...
Pitx2 confers left morphological, molecular, and functional identity to the sinus venosus myocardium
AIMS The sinus venous myocardium, comprising the sinoatrial node (SAN) and sinus horns (SH), is a region subject to congenital malformations and cardiac arrhythmias. It differentiates from symmetric bilateral mesenchymal precursors, but morphological, molecular, and functional left/right differences are progressively established through development. The role of the laterality gene Pitx2 in this...
