Abstract

Minor potential cardioembolic sources of stroke such as atrial septal aneurysms (ASA) or patent foramen ovale (PFO) are important risk factors for cryptogenic stroke. We aim to determine the prevalence of these abnormalities through an exhaustive etiological workup including transesophageal echocardiography and cervical arteries assessment in stroke patients younger than 60 years of age who had no evidence of a significant source of embolism. We classified 118 stroke patients into four groups according to transesophageal echocardiography (TEE) and cervical arteries assessment findings. Group A, consisted of 30 (25.4%) patients who had an arteriopathy likely related to stroke without any cardiac abnormality; Group B, 49 (41%) patients who had only a potential cardiac source; Group C, 9 (7.6%) patients who had an obvious arterial source of stroke and incidental cardiac abnormalities, and Group D, 30 (25.4%) patients who had neither cardiac nor arterial source. Data were analysed with X2 test for the comparison of risk factors between groups. Variance analysis was used to compare age between groups. Significance was assessed as p < 0.05. ASA represented 56.8% of the cardiac abnormalities and was diagnosed in 35.4% of the 79 patien...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
