prominent II and III cardiac arches Explanation: It seems that the cardiac arches are a reference to the cardiac silhouette. I suspect "prominence" may be a better term than "rounding". Not sure though, hence the low confidence. The fact that these "arches" are solely used to refer to the left-hand border of the silhouette suggests to me that "left" can be omitted. "Chest X-ray of aortic stenosis shows rounded profile of left ventricle (left third cardiac arch, white arrows), with slight enlargement of ascending ..." https://bit.ly/2ZiiCOX "Il BORDO SINISTRO della silouette cardiaca presenta tre archi distinti e precisamente da due convessità e una concavità. Il primo arco, superiore, piccolo e convesso è formato dall’arco aortico. Il secondo o arco medio, è rappresentato dalla concavità che corrisponde al tronco della polmonare ed alla prima porzione del suo ramo sinistro. Il terzo o arco inferiore, il maggiore dei tre, è un'altra convessità corrisponde alla parete anteriore e laterale (o libera) del Ventricolo Sinistro (VS). Una accentuazione di questo arco esprime alterazioni del ventricolo sinistro. All'unione del II con il III arco si trova l'auricola dell'Atrio Sinistro (AS) che normalmente appare indistinguibile." https://www.cuorevivo.it/radiografia del torace.htm "Chest X-ray showed prominent II and III cardiac arches and a lucent area between the aorta and pulmonary artery (Fig. 1)." https://www.researchgate.net/figure/Chest-X-ray-showing-the-... -------------------------------------------------- Note added at 13 hrs (2019-06-08 09:00:33 GMT) -------------------------------------------------- On second thoughts, you would need to include "left". -------------------------------------------------- Note added at 15 hrs (2019-06-08 10:49:34 GMT) -------------------------------------------------- Perhaps "left second and third arches show rounded profile" or something along those lines? |

2nd and 3rd branches of the left aortic arch with rounded contours Explanation: I don't think this is referring to the aortic arches. The aortic arches "are a series of six paired embryological vascular structures which give rise to the great arteries of the neck and head" See reference below. When googling '2nd and 3rd segments of left aortic arch' I was redirected to the branches of the aortic arch and I think this is the case here. Therefore, I would translate the sentence as follows: The longitudinal diameter of the cardiac silhouette is enlarged showing prominence of the 2nd and 3rd branches of the left aortic arch with rounded contours. I think the following link explains well the case here: left ventricular or "Shmoo" configuration describes lengthening and rounding of the left heart border with a downward extension of the apex resulting from left ventricular enlargement https://radiopaedia.org/articles/cardiac-silhouette?lang=gb Left aortic arch with ARSA or innominate artery: the aortic arch is properly located between the pulmonary artery and the trachea. https://www.sciencedirect.com/topics/neuroscience/aortic-arc... Round heart abnormally smooth arcuate contours of the heart on imaging due either to disease of the ventricles or to a falsecardiac appearance produced by excessive pericardial fluid. https://medical-dictionary.thefreedictionary.com/round heart Double aortic arch Occasionally, the right or left arch (or a segment) can be atretic. This is more common on the left side, and it is worth remembering that these atretic segments cannot be visualized by any current imaging modality https://www.sciencedirect.com/topics/medicine-and-dentistry/... On a frontal chest radiograph the mediastinal shadow of the left trachea above the level of the aortic arch is typically a low-density arcuate opacity (concave laterally) extending from the aortic arch to a point at or just above the medial end of the clavicle. https://books.google.co.uk/books?id=ByVqDwAAQBAJ&pg=PA15&lpg... Come si può notare che, in proiezione standard Postero-Anteriore della radiografia del torace, il Ventricolo Destro (VD) non interviene a delineare alcun profilo dell’ombra cardiaca. Pertanto le alterazioni del Ventricolo Destro si manifestano sul profilo radiografico del cuore solo in maniera indiretta sia attraverso l’arrotondamento del profilo superiore dell’arco medio di sinistra (che rappresenta l’aumento dell’arteria polmonare) sia per l’innalzamento della punta del cuore (apice cardiaco) che rappresenta indirettamente l’aumento del ventricolo destro. https://www.cuorevivo.it/radiografia del torace.htm |

| Reference: Anatomy of the Heart - Aortic arch Reference information: Anatomy of the Heart The aorta has a deep-seated origin and only becomes part of the cardiac silhouette as it arches upwards and backwards, forming a spiral with the pulmonary trunk. The ascending aorta arises in right posterior position relative to the pulmonary trunk (Figure 1, upper panel). It ascends superiorly, obliquely to the right and slightly anterior toward the sternum. On the right is the medial wall of the right atrium. Anteriorly are the right atrial appendage, the right ventricular outflow tract and the pulmonary trunk. The transverse pericardial sinus separates the back of the aorta from the left atrium and right pulmonary artery. The arch of the aorta begins just above the cuff of pericardial reflection, proximal to the origin of the brachiocephalic artery. The arch passes superiorly for a short distance before passing posteriorly to the left and finally terminating on the lateral aspect of the vertebral column. In its course, the arch gives origin to the neck and arm arteries https://www.textbookofcardiology.org/wiki/Anatomy_of_the_Hea... Che cos’è l’arco aortico? L'arco aortico, o arco dell'aorta, è quella porzione ricurva di aorta, che, in ogni rappresentazione del cuore umano, si nota portarsi dietro l'organo cardiaco. L'arco aortico comincia 5-6 centimetri dopo l'aorta ascendente (che è il primissimo tratto dell'aorta), si estende per una lunghezza circa uguale al tratto che la precede e termina dove comincia l'aorta discendente. Sulla sua faccia superiore – in genere nella parte centrale della curvatura – dà origine a tre ramificazioni arteriose di fondamentale importanza, le quali provvedono a rifornire di sangue gli arti superiori e la testa. Queste ramificazioni sono chiamate arteria succlavia sinistra, arteria carotide comune di sinistra e arteria anonima. https://www.my-personaltrainer.it/Foto/Aorta/arco_aortico.ht... Aortic Arch The aortic arch has three branches. The first, and largest, branch of the arch of the aorta is the brachiocephalic trunk, which is to the right and slightly anterior to the other two branches and originates behind the manubrium of the sternum. Next, the left common carotid artery originates from the aortic arch to the left of the brachiocephalic trunk, then ascends along the left side of the trachea and through the superior mediastinum. Finally, the left subclavian artery comes off of the aortic arch to the left of the left common carotid artery and ascends, with the left common carotid, through the superior mediastinum and along the left side of the trachea https://en.wikipedia.org/wiki/Aortic_arch Aortic arches The aortic arches or pharyngeal arch arteries (previously referred to as branchial arches in human embryos) are a series of six paired embryological vascular structures which give rise to the great arteries of the neck and head. They are ventral to the dorsal aorta and arise from the aortic sac. Arches 1 and 2 Note that the external carotid buds from the horns of the aortic sac left behind by the regression of the first two arches. Arch 3 The third aortic arch constitutes the commencement of the internal carotid artery, and is therefore named the carotid arch. It contributes to the common carotid artery and the proximal portion of the internal carotid artery https://en.wikipedia.org/wiki/Aortic_arches |
