Dec 1, 2018 · Of the complicated cases with an interarterial/intramural artery (1LCx*,R), 1 is found in the most common position seen in TGA, being right anterior, and 2 cases (1LCx*,R and 2RL*Cx) were seen in side-by-side great artery positions, mostly encountered in DORV.

Thus, the most common anatomy in TGA will be 1LCx-2R, where 1 and 2 denote the sinuses, L is left anterior descending artery, Cx is the circumflex artery, and R stands for the right coronary artery.

May 4, 2021 · Usual coronary artery anatomy (1LCx-2R) was present in 4 patients (50%). Era-specific impact on reoperation rate and common reoperation types could not be detected, except for aortic arch repair due to recoarctation ( Supplementary Material, Figs S1–S3 ).

Of these, 305 children (71%) had the CA anatomy “normal for transposition” (1LCx,2R (L—left anterior descending, Cx—left circumflex; R—right coronary artery)), 71 (16.7%) had 1L-2RCx pattern, and smaller percentages of cases had more complex and rarer forms of coronary anatomy as shown in Table 1.

Jun 23, 2023 · We sought to describe a single surgeon’s experience with aortic root translocation for complex TGA/VSD/LVOTO. We present a series of 12 patients with complex anatomy who underwent the Nikaidoh operation over the last 13 years.

Jun 25, 2021 · Patients were divided according to their coronary artery patterns using the Leiden convention 15 into groups with a usual pattern (1LCx‐2R), circumflex artery from the right coronary artery (1L‐2CxR), inverted origin (1R‐2LCx), partially inverted origin (1RL‐2Cx), double origin from sinus 1 (1R,LCx); double origin from sinus 2 (2LCx,R ...

Annotation of the normal anatomical pattern is 1R-2LCx, corresponding to the ‘surgical’ coding system. The ‘imaging’ coding system was made applicable for Computed Tomography (CT), Magnetic Resonance Imaging (MRI), echocardiography, and coronary angiography, thus facilitating interdisciplinary use.

A usual coronary artery pattern was defined as left anterior descending artery (LAD) and circumflex coronary artery (LCx) arising from sinus 1 and right coronary artery (RCA) from sinus 2...

Dec 1, 2023 · The postoperative 1R-2LCx variant in which the right coronary artery (RCA) originates from ‘sinus 1’ as defined by Gittenberger-de Groot et al. and the left coronary artery (LCA) from ‘sinus 2’ post ASO, was classified as ‘common coronary anatomy’ (pre-operative coronary anatomy was in these cases 1LCx-2R) and all other variants ...

Sep 10, 2013 · A usual coronary artery arrangement, with the left anterior descending and circumflex coronaries arising from sinus 1 and the right coronary arising from sinus 2 (classified as 1LCx-2R by the Leiden convention) was noted in 17 patients (40%), whereas the majority had various atypical branching patterns.
