A 33-year-old male patient with uncorrected tetralogy of Fallot was hospitalised for multiple peripheral arterial emboli. Bilateral above-knee amputation had been done after unsuccessful femoral embolectomy. A large thrombus was detected in the apical portion of the left ventricle which was the source of the embolus.The patient complained of mild frontal headache and progressive right-sided weakness shortly after an echocardiographic examination. A computed tomography (CT) scan revealed a left middle cerebral artery territory infarct. Patients with grown-up cyanotic congenital heart disease are at increased risk of thromboembolic cerebrovascular events. This report highlights the necessity for physicians to be alert for uncommon causes of acute stroke.

Objective: To determine the validity of a screening algorithm based on combination of clinical examination and pulse oximetry, for early detection of congenital heart disease (CHD) in term newborns. CHD is the most frequent major congenital anomaly, with prevalence of 6-12 per 1000 live births. Clinical examination alone may fail to detect CHD in more than 50% of affected newborns.

Prenatal sonographic diagnosis of congenital heart disease (CHD) can lead to improved morbidity and mortality. However, the diagnostic accuracy of ultrasound, the sole prenatal screening tool, remains limited. Failed prenatal or early newborn detection of cyanotic CHD (CCHD) can have disastrous consequences.

Background: Dextro-transposition of the great arteries (dTGA) stands out as a prevalent cyanotic congenital heart defect (CHD), characterized by an intricate reversal in the arrangement of the major arteries. In the past, several surgical procedures have been used to treat dTGA, including the atrial switch. Although the method is no longer used, survivors of the procedure still living among us.

Background: A high percentage of patients with congenital heart diseases (CHD) reach adulthood and, over time, require heart transplantation (HTx) or combined heart-lung transplantation (HLTx). Among CHD, there are subgroups associated with a higher risk.
Methods: Retrospective analysis of HTx and HLTx in CHD patients.
