Neonatal central cyanosis is always a sign of serious pathological processes and may involve diverse organs and impose a significant diagnostic and therapeutic challenge. Here, we report an unusual presentation of Ebstein's anomaly, a rare congenital heart malformation, as the cause of central cyanosis in a one-week-old full-term infant. Initiation of PEG(1) therapy in neonates with Ebstein's a...

A 24-year-old man presented with a history of palpitation and haemoptysis. He had short stature, cardiac anomalies physical deformities, including polydactyly, clubbing, cataracts cyanosis. Echocardiography was performed, revealing both atrial ventricular septal defects, along severe pulmonary hypertension Eisenmenger syndrome.

Atrial septal aneurysm (ASA) is a localised "saccular" deformity which protrudes to the right or the left atrium or on both sides. It is a rare, but well recognised cardiac abnormality. It is usually an incidental finding or may presents as atrial arrhythmias or arterial embolism. Though it is an acyanotic congenital heart disease but it may result in significant right to left shunt and cyanosi...

Methemoglobinemia, one of the rare causes of cyanosis and hypoxemia, may occur in congenital and acquired forms. Coexistence of cyanosis and hypoxemia suggests an etiology associated with an underlying cardiac disease firstly, but if any cardiac pathology exists pulmonary diseases are investigated generally. Considering bronchial asthma in a young patient with shortness of breath is usual. On t...

Differential cyanosis may occur in Eisenmenger physiology in the presence of a patent ductus arteriosus (PDA). We present a unique case of a 22-year-old male manifesting as cyanosis of the left upper extremity and both lower extremities, but with preservation of the right upper extremity. Work-up revealed multiple congenital defects, reminiscent of the Shone's complex. Survival into adulthood i...

This report describes a 52-year-old black male with the isolated finding of an anomalous superior vena cava draining into the left atrium. The patient presented with dizziness, mild cyanosis, polycythemia and normal cardiac and pulmonary findings. The first major diagnostic clue in this confusing clinical presentation was an unsuccessful lung perfusion scan in which intravenous tracer consisten...
