ABSTRACT
|
|
Introduction Morphological variations involving co-existence of left atria appendage (LAA) and patent ductus arteriosus (PDA) are extremely rare congenital anomaly. Case Report: This manuscript presents a case of a massive chicken-wing left atria appendage associated with a patent ductus arteriosus observed during a routine dissection of a 41-year-old embalmed male cadaver. The massive LAA overlaid the left cardiac artery and associated branches and great cardiac vein. Conclusion: Cardiac and vascular dysgenesis may arise due to activation or inactivation of embryonic transcription factors by any atypical factor. The resulting anomalies may present with clinical symptoms or could be asymptomatic. Knowledge on the co-existence and developmental variations of these two anatomical structures (LAA and PDA) is of importance in clinical presentation. Keywords: Left atrial appendage, Persistence ductusarteriosus, Variation |
