Introduction: Patent ductus arteriosus (PDA) is often recognized and treated with percutaneous closure in adults. However, the impact on cardiac reverse remodeling following PDA closure in adults is not clear. We performed a meta-analysis to characterize the extent of cardiac remodeling following percutaneous PDA closure in adults. Methods: MEDLINE and EMBASE were systematically searched for original studies that reported echocardiographic variables at baseline, immediately post-procedure (within 24 hours), and at follow-up (>1 month) in adults undergoing percutaneous PDA closure. Additionally, we included echocardiographic data from a cohort of patients >18 years of age that underwent percutaneous PDA closure between 01/2015 and 12/2019 at our centre. For parameters with sufficient data for pooling, weighted averages were calculated, and pooled differences were presented as weighted mean differences. Heterogeneity was assessed using the I 2 statistic. Results: After screening 278 abstracts, 5 studies were identified. When combined with our own cohort of 13 patients, our meta-analysis encompassed 244 patients. The weighted mean age of all patients was 33 years with all studies predominantly comprised of female patients and the median follow-up was 12 months (ranging from 1 month- 5 years across the studies). When compared to baseline, left ventricular ejection fraction (LVEF) decreased significantly immediately post-procedure and all parameters significantly decreased at follow-up (Table 1). Conclusions: As demonstrated by the decreases in the left ventricular and left atrial sizes, reverse remodeling was observed in adults who underwent percutaneous PDA closure. The significantly lower LVEF immediately post-procedure could reflect withdrawal of chronic volume overload or increased afterload. The clinical significance of the statistically significant lower LVEF on follow-up testing is unclear and requires further evaluation.

The present study aimed to propose the pulmonary hypertension for predicting left ventricular dysfunction in adults after patent ductus arteriosus closure. A total of 183 patients (age ≥18 years) after patent ductus arteriosus occlusion were retrospectively collected in this study. In brief, pre-, post-procedure and short-term follow-up transthoracic echocardiography were performed. Simpson’s method was used to measure the left ventricular ejection fraction (LVEF), and LVEF less than 50% after procedure was utilized as a criterion to identify left ventricular dysfunction. As a result, 36 (19.67%) patients developed newly identified left ventricular dysfunction. The rate of newly identified left ventricular dysfunction was significantly higher in moderate or severe pulmonary hypertension groups compared to the groups of mean pulmonary artery pressure (mPAP) <25 mmHg (P < .001). Logistic regression analysis showed that elevated mPAP ( ≥25 mmHg) was an independent predictive value for newly identified left ventricular dysfunction (OR = 3.584, 95%CI: 1.186–10.832, P = .024) after adjusting confounders. The ROC curve revealed a good discrimination power for predicting newly identified left ventricular dysfunction (AUC = 0.924, 95%CI: 0.885–0.963, P < .001). Taken together, newly identified left ventricular dysfunction after patent ductus arteriosus closure was prevalent in patients with elevated mPAP. The pre-procedure elevated mPAP is an independent risk factor for the prediction of the newly identified left ventricular dysfunction in adult patients undergoing percutaneous patent ductus arteriosus closure. It is feasible to propose a risk model for predicting post-procedure left ventricular dysfunction and a heart function monitoring in pulmonary hypertension patients.

Abstract Background Patent ductus arteriosus poses diagnostic and therapeutic dilemma for clinicians, diagnosis of persistent PDA, and determination of its clinical and hemodynamic significance are challenging. The aim of this study is to determine the prevalence of PDA in preterm infants admitted to our NICU, to report cardiac and respiratory complications of PDA, and to study the management strategies and their subsequent outcomes. Result Echocardiography was done for 152 preterm babies admitted to neonatal intensive care unit (NICU) on day 3 of life. Eighty-seven (57.2%) preterms had PDA; 54 (62.1%) non-hemodynamically significant PDA (non-hsPDA), and 33 (37.9%) hemodynamically significant PDA. Hemodynamically significant PDA received medical treatment (paracetamol 15 mg/kg/6 h IV for 3 days). Follow-up echocadiography was done on day 7 of life. Four babies died before echo was done on day 7. Twenty babies (68.9%) achieved closure after 1st paracetamol course. Nine babies received 2nd course paracetamol. Follow-up echo done on day 11 of life showed 4 (13.7%) babies achieved successful medical closure after 2nd paracetamol course; 5 babies failed closure and were assigned for surgical ligation. The group of non-hsPDA showed spontaneous closure after conservative treatment. Pulmonary hemorrhage was significantly higher in hsPDA group. Mortality was higher in hsPDA group than non-hsPDA group. Conclusion Echocardiographic evaluation should be done for all preterms suspected clinically of having PDA. We should not expose vulnerable population of preterm infants to medication with known side effects unnecessarily; we should limit medical closure of PDA to hsPDA. Paracetamol offers several important therapeutic advantages options being well tolerated and having more favorable side effects profile.

M-mode echocardiographic features suggesting a patent ductus arteriosus are based on two groups of indirect criteria: dilation of the left cardiac cavities and changes of systolic time intervals. The reliability of the first group of criteria has been questioned in fluidlimited, mechanically ventilated preterm infants. The sensitivity of the systolic time intervals in the same circumstances is investigated. Twenty-three patients with a large patent ductus arteriosus were selected. Review of their echocardiograms shows that the sensitivity of the various criteria (expressed as percentage of positivity) was as follows: inversion of the ratio of left ventricular preejection period to right ventricular preejection period, 91.3%; left ventricular preejection period to left ventricular ejection time over right ventricular preejection period to right ventricular ejection time &lt; 1, 83%; left atrium dilation, 74%; shortening of left ventricular preejection period, 70%; dilation of left ventricular internal dimensions in diastole, 65%; increase in left atrium/aorta, 52%; and decrease of left ventricular preejection period to left ventricular ejection time, 48%. Three criteria involving time intervals (left ventricular preejection period to right ventricular preejection period, left ventricular preejection period, and left ventricular preejection period to left ventricular ejection time) had 100% specificity. The lowest specificity was found with criteria involving the left atrium (left atrial to aortic root ratio 75% and left atrium 63%). It is concluded that study of systolic time intervals is a reliable means of detecting preterm infants with hemodynamically significant left-to-right shunt through a patent ductus arteriosus even if the infants are mechanically ventilated and fluid restricted.

Preterm infants commonly present with a hemodynamically significant patent ductus arteriosus (hsPDA). The authors describe the case of a preterm infant with posthemorrhagic ventricular dilation, which resolved in a temporally coincident fashion to repair of hsPDA. The presence of a PDA with left-to-right shunting was confirmed at birth on echocardiogram and was unresponsive to repeated medical intervention. Initial cranial ultrasound revealed periventricular-intraventricular hemorrhage. Follow-up serial ultrasound showed resolving intraventricular hemorrhage and progressive bilateral hydrocephalus. At 5 weeks, the ductus was ligated with the goal of improving hemodynamic stability prior to CSF diversion. However, neurosurgical intervention was not required due to improvement of ventriculomegaly occurring immediately after PDA ligation. No further ventricular dilation was observed at the 6-month follow-up.Systemic venous flow disruption and abnormal patterns of cerebral blood circulation have been previously associated with hsPDA. Systemic hemodynamic change has been reported to follow hsPDA ligation, although association with ventricular normalization has not. This case suggests that the unstable hemodynamic environment due to left-to-right shunting may also impede CSF outflow and contribute to ventriculomegaly. The authors review the literature surrounding pressure transmission between a PDA and the cerebral vessels and present a mechanism by which PDA may contribute to posthemorrhagic ventricular dilation.
