“…Those echocardiographic markers were persistently reduced at the end of test period (D30). Similar finding have also been reported in dogs [8,19]. Interestingly, the iLVIS and ESVI indicating LV myocardial contractibility were not significantly changed after ductal closure.…”

“…Earliest favorable echocardiographic signs for successful ductal closure in dogs with PDA are the reduction in LVID/ Ao, iLVID and EDVI, which indicates LV volume reductions at diastole [8]. In this study, significant reductions in the LVID/Ao, iLVID and EDVI were observed from D1 after ductal closure.…”

“…Although successful closure of PDA can be determined by loss of heart murmur by auscultation or echocardiographic evaluation on the shunt flow at pulmonary artery (PA), long-term outcome after the ductal closure can be more accurately assessed by echocardiography and cardiac biomarker assay [7,8,[17][18][19].…”

“…The echocardiography is the best tool for characterizing and assessing PDA in human and small animals [4,7,8,18,19]. Several echocardiographic markers have evaluated for the surgical and interventional outcome after ductal closure in dogs [8,19].…”

“…Several echocardiographic markers have evaluated for the surgical and interventional outcome after ductal closure in dogs [8,19]. Known echocardiographic features indicating poor prognosis of PDA include increased left atrial to aortic root ratio (LA/Ao), left ventricular end-diastolic dimension to aortic root ratio (LVID/Ao), indexed left ventricular end-diastolic (iLVID) and end-systolic dimensions (iLVIS), end-diastolic (EDVI) and end systolic volume index (ESVI), and the presence of mitral regurgitation [8].…”

This study evaluated several known echocardiographic markers related to the assessment of severity in dogs with patent ductus arteriosus (PDA) after the closure of ductus arteriosus (DA). Forty-two dogs with patent ductus arteriosus were enrolled in this study. Evaluated echocardiographic markers were left atrial to aortic root ratio, left ventricular end-diastolic dimension to aortic root ratio, indexed left ventricular end-diastolic and end-systolic dimensions, end-diastolic and end systolic volume index, pulmonic flow to systemic flow (Qp/Qs) ratio, velocities of pulmonary regurgitant and systolic jets, pulmonary flow profiles and the presence of mitral regurgitation. Those markers were evaluated before, 1 day, and 30 days after the closure of DA. Statistically significant changes in some echocardiographic markers (i.e., Qp/Qs) were observed. Although several studies in human and dogs have evaluated the clinical outcome of PDA occlusion using several echocardiographic markers, this study has firstly evaluated all echocardiographic markers known to be useful for assessing the clinical outcome of PDA occlusion in human, and has demonstrated that those markers including the Qp/Qs and pulmonary flow profiles were useful in evaluating of clinical outcome of PDA in dogs and the reduction of LA and LV preload after ductal closure could dramatically reduce after successful ductal occlusion of PDA in dogs.
