The Relationship Between Maximal Atrial Septal Excurtion and Left Atrial Appendix Flow In Cryptogenic Stroke Patients Without Patent Foramen Ovale

Abstract

OBJECTIVE: to examine whether a correlation exists between LAA systolic flow velocity and maximal atrial septal excurtion(MASE)In Cryptogenic stroke patients without Patent foramen ovale METHODS:This study includes 30 patients aged between 18-65 years, with cyrptogenıc stroke diagnosis .Followed a medical history and a physical examination,each patient underwent Electrocardıografic (ECG) and Transtorasic Echocardiographic (TTE) examination.Two dimensional TTE ,M-mode and Doppler studies were performed using standart techniques.In the Subkostal imaging;Atrial septal excurtion(MASE) was measured by putting M-mode cursor on midseptum.After TTE,patients underwent Transesophageal Ecocardiography (TEE). Left atrial appendix (LAA) systolic flow velocity was measured by putting pulse wave doppler cursor on LAA outflow.Associations between LAA systolic flow velocıty and MASE were determined by using spearman correlation coefficient. RESULTS: A negative correlation was observed between LAA systolic flow velocity and MASE .When relations among ecocardiographic parametres (LADD, LVEDD, E,A,E',A', Des Time) were examined one by one, no other significant correlatıon was observed. CONCLUSIONS: Accordıng to our study's results;we thınk that the increase of MASE may be an indicator for the decrease of LAA systolic flow velocıty. Thıs result would keep lıght to the other future compherensive studıes which contaıns other parametres whıch may affect and may reflect LAA functıon .
