| Abstract | ||
| Introduction: Large uncomplicated atrial septal defect (ASD) alters the pulmonary venous flow (PVF) pattern. The left atrial appendage (LAA) flow characteristics in ostium secundum (ASD) have not been previously studied in detail. Objective: We aimed to study the alteration in PVF flow pattern in relation with LAA in patients with large uncomplicated ASD. Patients & Methods: The correlation between LAA flow pattern and PVF pattern were assessed in (29) subjects, with ASD. The mean age of the study group was (36 ± 12.142 years). All subjects in sinus rhythm, which were examined with transthoracic (TTE) and transesophageal echocardiography (TEE). Results: LAA flow pattern and PVF pattern were adequately recorded in 29 subjects with ASD. Maximum diameter (1.4cm) to (3.90 cm). The mean age of the study group was (mean ± SD: 36 ± 12.142) years. All patients with sinus rhythm. Continuous antegrade wave (CAW) of PVF pattern (mean ±SD:52.52 ±10.683 cm/sec) replaced normally occurring S and D wave in all ASD patients. The atrial reversal wave was reduced (mean ± SD: 23.629 ± 6.29 cm/sec). There is strong correlation between peak LAA contraction velocity and peak CAW velocity of PVF (r = -0.5269 P< 0.001). Conclusions: Transesophageal Doppler echocardiography of LAA flow and PVF patterns in patients with ASD can help to estimate ASD hemodynamics. And may add as a new diagnostic way for the defect.
