A Case of Congenitally Corrected Transposition of Great Arteries: An Infrequent Happenstance.

Congenitally corrected transposition of the great arteries (CCTGA) is rare form of congenital heart diseases. It may be present with or without associated anomalies. Patients with CCTGA are usually diagnosed at early stages of life due to associated anomalies, but they may even remain asymptomatic till later decades of their life. We report a case of a 42-year-old man who presented at neurosurgery department with dizziness, seizures, and loss of consciousness, in whom isolated CCTGA was discovered incidentally. Further investigation depicted right ventricular hypertrophy, mild valvular regurgitation, mildly dilated pulmonary artery, low heart rate with AV dissociation, and third-degree heart block. These indicated for implantation of permanent pacemaker into the patient. The implantation of VVI mode pacemaker was uneventful and the patient is being followed up in the past eight months in favorable condition.

Surgical exclusion of postsurgical pseudoaneurysm of the ascending aorta.

Pseudoaneurysm of ascending aorta after cardiac surgery is rare in children. We report a case of successful surgical exclusion of ascending aortic pseudoaneurysm in a 15-year-old boy. The neck of the aneurysm was in close proximity to the right coronary artery (RCA).

Zidovudine-induced reversible pure red cell aplasia.

Hematological abnormalities are frequent among human immunodeficiency virus (HIV)-infected patients and may be directly attributable to the virus or may be caused by opportunistic infections, neoplasms or drugs that cause bone marrow suppression or hemolysis. Pure red cell aplasia (PRCA) is an uncommon hematological disorder that causes anemia. We report a 37-year-old male with HIV infection who developed PRCA 6 weeks after commencing Zidovudine and recovered following cessation of the drug. This is the first case of Zidovudine-induced PRCA reported from the Indian subcontinent.
