Knowledge of normal range of Left Atrial size is important for physicians and cardiologist to diagnose and manage cardiac diseases with dilated left atrium like Mitral Valve Diseases, dilated cardiomyopathies.
In present work TTE (Trans Thoracic echocardiography) was chosen to measure Left atrial size as it is commonly used diagnostic modality of present time to reveal in vivo anatomy and function of heart. Left Atrial Antero posterior dimension is commonly measured on Trans Thoracic echocardiography (TTE) to assess Left atrial size. The purpose of present study was to find standard range of commonly measured Left Atrial Antero posterior dimension with transthoracic echocardiography in patients with normal left and right ventricular function.
With the permission of ethical committee and consent of patient; total 104 patients (42 male and 62 female) were included in this study. The mean age of present study population was 44.64 years. The range of Left Atrial AP dimension by 2D guided M mode for total study population was (18 to 40)mm with mean ±S.D was 30.64mm ± 4.10mm.
Indians have different physical characteristics than western population; the study parameter was evaluated for its relation with height, weight and Body Surface Area. Statistical findings showed significant correlation between study dimension and these physical parameters. The study concludes that these physical parameters should be taken into account while considering normal ranges of LA AP dimension for respective population.
Keywords: Left Atrial Antero Posterior dimension, M mode echocardiography.
