Distribution of Valvular Heart Disease in Un-explained Stroke/Transischemic Attacks Patients

Abstract

Background: Today cerebrovascular events are increased. Most of the phenomenon can not be explained. Substantial proportion of cases charged in cardiovascular events such as hypertension, atrial fibrillation and coronary artery disease. Especially related complications such cardiac events are accused thromboemboli and hemorrhagic. Objective: cerebrovascular events studies and surveys point out the distribution of cause. Our small size survey try to find distribution of valvular heart disease in cerebrovascular events. Methods: During the 2006 to 2014 period total 311 TIA and stroke patients were evaluated in 3 different centers. TIA and stroke definition were defined according to AHA/ASA (1). Patient ECG, echocardiography, comorbitidies, past history and medication were collected. In our study atrial fibrillation, stenotic or ulcerative carotide and aortic arch pathology, existence of any degree of mitral stenosis were excluded (n = 36). According to these criteria 219 of 311 patients were accepted (101 TIA and 118 stroke, 81 male mean age 71 ± 4). Valvular disease was classified ACC / AHA criteria (2). Results: In our study find out 11.9 % mitral regurgitation, 17.8 % aortic regurgitation, 5.5 % mitral and aortic regurgitation were found. 33.8 % patients had isolated mitral stenosis (16.4%) or with regurgitation (17.4 %), 14.2 % has aortic regurgitation with stenosis. Aortic regurgitation was the most frequent valvular disease. Table 1 and 2 were shows the detail. Discussion and conclusion: We found that increase in mitral stenosis in stroke. But another finding of our study was isolated aortic regurgitation also increased in stroke and TIA. These findings may be explained by the increase of age, another hypothesis was; aortic leak can slow left atrial outflow (3).
