Cardiac disease in young children can be unrecognized until symptoms are unmasked by a precipitating event, such as an infection. We present a case of anomalous left coronary artery from the pulmonary artery causing clinically significant disease in a four-month-old male with concomitant mitral regurgitation and pulmonary coccidioidomycosis who required modification of his surgical management due to the infection. This case highlights how timely diagnosis and perioperative management and recovery can be affected by concurrent infections in patients with congenital heart disease.

A patient with known pulmonary atresia and intact ventricular septum and ductal stent presented with low cardiac output and arrythmia. Intraoperatively, the patient was found to have an anomalous left coronary artery arising from the pulmonary artery. After reimplantation of the left coronary artery to the aortic root and placement of a central shunt, the patient progressed well and was discharged home.

Background: An anomalous left vertebral artery (aLVA) can complicate aortic arch surgery. We examined the safety of various aLVA revascularization strategies during open total arch replacement.

Methods: We retrospectively evaluated 92 patients undergoing total arch replacement from January 2018 to May 2023 and identified 11 patients with aLVA.

Incidentally Discovered Anomalous Mitral Chordae at the Time of Mitral Valve Repair.

Ann Thorac Surg Short Rep

September 2024

Department of Cardiovascular Surgery, Mayo Clinic, Rochester, Minnesota.

Anomalous supravalvular mitral chordae tendineae that originate from the mitral leaflet(s) and attach to the interatrial septum or dome of the left atrium are a rare congenital anomaly. These supravalvular chordae are often associated with severe mitral regurgitation and surgical experience has included resection of the anomalous chord as part of the repair. We describe an unusual presentation of an incidentally discovered anomalous supravalvular chord at the time of mitral valve repair for degenerative mitral regurgitation related to a flail posterior leaflet.

Undetected coronary anomalies at Norwood procedure are associated with poor prognosis due to inadequate myocardial protection. We report a case of anomalous origin of the right coronary artery from the main pulmonary artery trunk with hypoplastic left heart syndrome and aortic atresia. Although, during bilateral pulmonary artery banding as initial palliation, the proximity between the right coronary artery origin and the aortic root made a visual diagnosis difficult, it was diagnosed using computed tomography before the Norwood procedure.
