“…One hypothesis for the relationship between LV hypertrophy and mortality relates to abnormal coronary artery perfusion 20. Donnelly and coworkers studied regional blood flow in HLHS using position emission topography and demonstrated that coronary perfusion to the right ventricle in HLHS was decreased compared with controls, with a disproportionate amount diverted towards the hypoplastic left ventricle.…”

“…In addition, the steal phenomenon of epicardial coronary flow by fistula is further considered an intrinsic coronary abnormality, particularly if it is associated with myocardial hypertrophy, as observed in the subgroup with mitral stenosis, which compromises myocardial perfusion [13]. These coronary fistulas usually arise from the left coronary artery branches [14].…”

Introduction: Although hypoplastic left heart syndrome (HLHS) is extensively studied this disease still has a high mortality rate compared to other diseases treated as univentricular physiology. In this context, morphological differences between phenotypes within the spectrum of HLHS may be recognized as risk factors, and their identification can assist in choosing treatment between subgroups.Objective: To identify the most prevalent form of coronary artery dominance in HLHS in subgroups with atresia and mitral stenosis.Methods: Analysis of the coronary anatomy according to the distribution of epicardial branches and the dominance patterns classified as right, left, or balanced (co-dominant). Control group was composed of nine specimens of morphologically normal hearts; the HLHS group consisted of nine specimens with MA and 24 specimens with MS. We applied Chi-square test for statistical analysis.Results: There were significant differences between the two groups in relation to coronary artery dominance (÷2 = 9.298; P = 0.01). Left dominance was present in 75% of MS cases and the balanced (co-dominant) dominance was observed only in MS. In the control group, right dominance was observed in all cases (P <0.01).Conclusions: Left dominance is more common in HLHS than in the control group of normal hearts and in HLHS. The left coronary dominance is more frequent in the subgroup with mitral stenosis.Descriptors: Heart/anatomy & histology. Coronary vessels. Hypoplastic left heart syndrome. Heart defects, congenital.

“…The exact incidence of the association of these lesions with anomalous coronary arteries is unknown. The majority of reports involves case series or single case studies 1–16 . The most common coronary anomalies associated with left‐sided lesions consist of ventriculocoronary fistulas or coronary tortuosity; 14 anomalies of coronary origin are less common.…”

Anomalies of Left Coronary Artery Origin Affecting Surgical Repair of Hypoplastic Left Heart Syndrome and Shone Complex

There has traditionally been less concern regarding coronary anomalies with left-sided congenital heart lesions such as hypoplastic left heart syndrome (HLHS)or Shone complex than with other lesions. However, coronary anomalies in this setting can profoundly affect surgical intervention, particularly when surgical repair involves the ascending aorta. We describe four patients with congenital left-sided heart lesions in which left coronary artery (LCA) anomalies substantially affected intervention and outcome. In the first two cases, the coronary anomalies were not identified prospectively and resulted in surgical injury directly to the coronary or to its surrounding region. In the latter two cases, successful identification of the coronary anomaly preoperatively allowed for modification of surgical technique and/or intervention. We conclude that detailed coronary artery assessment should be part of the routine echocardiographic evaluation of congenital left-sided heart lesions that require surgery.
