Development of the pulmonary veins; with reference to the embryology of anomalies of pulmonary venous return.
TLDR
The examination of serial sections of human embryos between 24 and 34 days and the use of plastic reconstructions showed that the common pulmonary vein develops as an outgrowth from the medial superior wall of the left auricle and unites with the angioblastic plexus of the developing lung bud.Abstract:
The examination of serial sections of human embryos between 24 and 34 days (3 to 11 mm) and the use of plastic reconstructions, showed that the common pulmonary vein develops as an outgrowth from the medial superior wall of the left auricle and unites with the angioblastic plexus of the developing lung bud. No evidence was found that the vein connects directly with the sinus venosus in the early stages, and later shifts in position as the atrial septum grows. Anomalous pulmonary venous drainage is classified in four main types, and theories of development are briefly discussed.read more

TL;DR: A classification of the newly named pulmonary malinosculation spectrum is presented, which includes all congenital lung anomalies where there is abnormal connection of one or more of the four major components of lung tissue--namely, tracheobronchial airway, lung parenchyma, arterial supply, and venous drainage.

Cor triatriatum: Pathologic anatomy and a consideration of morphogenesis based on 13 postmortem cases and a study of normal development of the pulmonary vein and atrial septum in 83 human embryos
TL;DR: The pathologic and embryologic findings strongly suggest that cor triatriatum results from entrapment of the left atrial ostium of the common pulmonary vein by tissue of the right horn of the sinus venosus from which septum primum develops, leading to failure of incorporation of theCommon pulmonary vein into theleft atrium during the fifth embryonic week.
