Anomalous aortic origin of the left main coronary artery associated with arterial compression-Case report.

BACKGROUND: Anomalous aortic origin of coronary artery is a rare finding, with varied presentation and symptomatology. Increasingly recognized by cardiac imaging, when found it raises questions about the appropriate approach and management. CASE PRESENTATION: We present a case of an 11-year-old female who presented with episodes of shortness of breath, angina, and syncope during exercise. Further investigation demonstrated episodes of nonsustained ventricular tachycardia on Holter and coronary angiotomography revealed that the left coronary artery had an anomalous origin from the right cusp with initial short intramural segment and significant external compression in its initial course between the aorta and the pulmonary artery. The patient was submitted to surgical correction with dissection of left coronary artery posterior to the pulmonary artery, coronary arteriotomy, roof ampliation with the autologous pericardium, and creation of neo-ostium in aorta. The patient had a satisfactory postoperative recovery, was discharged on the fifth-day post-op, and remains asymptomatic after 14 months of follow-up. Herein we present surgical video and postoperative echo and computed tomography scan.

Prognostic value of the preoperative neutrophil-lymphocyte ratio in patients undergoing the bidirectional Glenn procedure.

INTRODUCTION: The neutrophil-lymphocyte ratio (NLR) has been associated with worse outcomes in patients undergoing coronary artery bypass graft surgery. Little is known about this association in the pediatric population who require surgery for congenital heart defects, especially in patients with a single ventricle (SV). OBJECTIVE: To analyze the association of the preoperative NLR with outcomes in patients undergoing the bidirectional Glenn procedure. METHODS: This study involved a retrospective cohort analysis of 141 consecutive patients with SV undergoing the bidirectional Glenn procedure between January 2011 and December 2017 in two centers. The preoperative NLR was included in the last hemogram test before surgery. According to the NLR level, the patients were divided into group I (NLR < 1), group II (NLR between 1 and 2), and group III (NLR > 2). The primary endpoint was total hospital length of stay (LOS), and secondary endpoints were mechanical ventilation (MV) time, intensive care unit (ICU) LOS, ventricular dysfunction, complications, and middle-term mortality. RESULTS: The average follow-up duration was 48 months. There were 61, 47, and 33 patients in groups I, II, and III, respectively. Patients in group III exhibited an increased risk of prolonged total hospital LOS (P = .00). An increase in MV time (P = .03) and ICU LOS (P = .02) was also observed in this group, and these patients experienced greater mortality in 24 months following the surgery (P = .03). There was no association between the NLR and ventricular dysfunction (P = .26) and complications (P = .46). CONCLUSION: A high preoperative NLR was associated with worse outcomes in patients with SV physiology undergoing the bidirectional Glenn procedure.
