Sequential diagnosis of coronary arterial anatomy in congenitally corrected transposition of the great arteries

Coronary artery anatomy in anatomically corrected malposition of the great arteries and their surgical implications

“…1). These findings were concordant with our previous reports [9,10,11,13] that the CA pattern is mainly influenced by the APR.…”

“…Because there are three major CAs and usually they penetrate the two aortic sinuses facing the pulmonary trunk, there would be only six (3 Â 2) possibilities for the basic arrangement of CA (designating three major CAs into a single facing sinus as their variant subtypes). Our previous studies [9,10,11,13] have confirmed the relationship between the six major coronary patterns and APR. In patients with ventriculoarterial 'discordance' (TGA, CCTGA), it is the 'geographic' relationship of the aortic root and the pulmonary annulus, but not the 'discordant' ventriculoarterial connection that resulted in coronary anomalies.…”

“…Previously, we reported that the CA pattern is related to the aortopulmonary rotation (APR) in complete transposition of the great arteries (TGA) [9,10], Fallot's tetralogy [11], persistent truncus arteriosus [12], and congenitally corrected transposition of great arteries (CCTGA) [13] (Fig. 1).…”

Congenitally corrected transposition of the great arteries: MDCT angiography findings and interpretation of complex coronary anatomy

“…The result is functional correction, in that oxygenated blood comes into LA, goes to morphologically RV, and than flows out to the aorta. Adult patients with CCTGA do not have a benign condition and rarely survive to old age [8]. The patients with this anomaly survive past 50 years of age because of associated congenital intracardiac anomalies such as pulmonary stenosis and ventricular septal defect, or systemic AV valve (anatomical tricuspid) abnormality [1].…”

Restoration of Transposed Great Arteries With or Without Subpulmonary Obstruction to Nature

“…In short, for JOCA near the facing commissure, a superiorly based trapdoor (single-button technique) or lateral funnel (two-button technique), and near the nonfacing commissure, a medially based trapdoor, are vital for coronary redirection. The categorization of CA based on the aortopulmonary rotation can be applied to all congenital heart defects and normal hearts (Chiu et al, 2000a;Chiu et al, 2002a;Chiu et al, 2003;Huang et al, 2011;.…”
