Crossed pulmonary arteries (CPAs) represent an uncommon anatomic variant, usually associated with some specific syndromes and conotruncal defects. This finding has been described in 22q11.2 Deletion Syndrome (22q11.2DS). We evaluated the correlation between CPAs and genetic diseases, in order to better define the characteristics of this variant, considered a rare anatomic pattern. An in-depth analysis of CPAs genotype-phenotype correlations was performed via a literature review. We detected 74 CPAs patients through echocardiography. Of these 74 patients, 35.1% of patients showed additional intracardiac malformations, while 29.7% showed extracardiac vascular anomalies, of which 16.2% were associated with intracardiac defects and 13.5% were not. In all, 62.2% of patients were diagnosed with genetic diseases and 52.2% of them were 22q11.2DS patients. In conclusions, CPAs represent a cardiovascular variant, which is detectable in nonsyndromic individuals, but especially in various genetic syndromes and in particular in 22q11.2DS patients. Data on the real prevalence of this morphology is lacking in literature. Knowledge of this anatomic variant is useful to interpret the unusual course of the pulmonary branches and is helpful information before cardiovascular surgical correction. Moreover, due to the strong association of CPAs with some genetic syndromes, the identification of this anatomic pattern can indicate the utility of a genetic assessment of these patients.

“…The concomitant pulmonary artery abnormalities such as crossed pulmonary artery and pulmonary artery stenosis are essential in performing the surgery [6,14]. In addition, during PTA surgical procedure, detachment of the pulmonary arteries from the arterial trunk was necessary to form a right ventricle to pulmonary artery conduit.…”

“…It has been widely applied to cardiovascular examinations in recent years [8][9][10][11][12][13]. To the best of our knowledge, original researches with a certain number of patients focusing on the preoperative evaluation on DSCT were rare [14][15][16]. Therefore, the purpose of this study is to comprehensively assess the morphological features of PTA on lowdose DSCT and compare its diagnostic accuracy for associated cardiovascular anomalies with that of TTE.…”

BackgroundTo assess the morphological features of persistent truncus arteriosus (PTA) on low-dose dual-source computed tomography (DSCT) and compare its diagnostic value for associated cardiovascular anomalies with that of transthoracic echocardiography (TTE).Methods:Twenty-four PTA patients were enrolled in this retrospective study. The types of PTA, diameters of the truncus artery (TA), main pulmonary artery (MPA), right pulmonary artery (RPA), left pulmonary artery (LPA), and ventricular septal defect (VSD) on DSCT were recorded. Besides, all associated cardiovascular abnormalities were assessed. The diagnostic performance of DSCT and TTE for associated anomalies were compared. The effective doses of DSCT were calculated.Results:Four types were found: type A1(n=13/24, 54.17%), type A2(n=7/24, 29.16%), type A3（n=3/24, 12.50%）and type A4(n=1/24,4.17%). The mean diameter of VSD, TA, MPA, RPA, and LPA was 1.47±0.56cm, 3.92±1.56cm, 2.27±1.65cm, 1.48±0.74cm and 1.38±0.66cm, respectively. 78 associated cardiovascular anomalies were confirmed. The most common associated abnormalities were VSD (100%), right-sided aortic arch (33.33%) and aortopulmonary collateral vessels (29.17%). Although TTE was better at diagnosing intracardiac anomalies (accuracy:99.17% vs. 95%; sensitivity: 97.06% vs. 88.24%; specificity: 100% vs. 97.67%), DSCT had an advantage in diagnosing the associated cardiovascular abnormalities (accuracy: 98.61% vs. 96.07%; sensitivity: 94.87% vs. 82.05%; specificity: 99.44% vs. 99.15%). The estimated mean effective doses was 0.98±0.37mSv (＜1mSv). Conclusions:Low-dose DSCT could accurately confirm the morphological features of PTA. Compared to TTE, low-dose DSCT is a better diagnostic tool for associated cardiovascular abnormalities. Combining with TTE will be beneficial to provide more accurate information for clinical interventions.
