CTICasesSeparate Origins of the Left Pulmonary Artery with Endocardial Cushion Defect and Repaired Tracheoesophageal Fistula
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Complex congenital heart disease including an endocardial cushion defect with abnormal mitral and tricuspid apparatus and an abnormal atrium. The main pulmonary trunk gives rise to one branch for the left pulmonary artery, but then a separate distal main branch also originates, supplying the lingula and left upper lobe, indicating separate origins of the left pulmonary artery. A history of repaired tracheoesophageal fistula is also noted.
Key takeaways
Complex congenital anomalies can involve unusual pulmonary artery origins, such as separate origins for different segments of the left pulmonary artery, often coexisting with other severe cardiac defects like endocardial cushion defects and other systemic malformations like tracheoesophageal fistula.
