Presentation
Dyspnea and tachypnea have been diagnosed as symptoms of high-output cardiac failure.
Patient Data
Ectatic ascending aorta measuring about 4.5 cm.
Aortic valve replacement is noted.
No obvious pathology is noted in the visualized part of the lung.
Sternotomy wire is noted.
There is systemic arterial supply to a normal lung (right lower lung lobe) arising just to the left side of the celiac artery origin, but with no accompanying bronchial sequestration seen, suggesting anomalous systemic arterial supply to normal lung (Pryce type 1 sequestration).
Case Discussion
Anomalous systemic arterial supply to a normal lung is a rare condition in which functioning lung tissue, typically the basal lung segments, mainly of the left lower lobe, is supplied by an anomalous systemic artery.
Pryce (1) classifies it as a type 1 intralobar sequestration, where there is systemic arterial supply to a normal lung.
Patients may be asymptomatic or may present with hemoptysis, a heart murmur, or congestive heart failure, as observed in our patient.
