Aim: To determine the prevalence of pulmonary hypertension (PH) and its associated factors among end-stage renal disease (ESRD) patients who underwent maintenance dialysis.Methods: A total of 491 patients received echocardiography examinations and underwent pulmonary artery systolic pressure (PASP) assessments. A subgroup of 283 patients were subjected to plasma creatinine (Cr) and blood urea nitrogen concentration (BUN) tests, routine blood examinations and electrolyte analysis. First, we compared the differences in echocardiographic, Cr and BUN, blood routine and electrolyte parameters between PH and non-PH groups. The correlations between PASP and the parameters mentioned above were also analyzed. Furthermore, univariate and adjusted logistic regression analyses were performed to identify the independent associated factors.Results: The incidence of PH among ESRD patients who were treated with maintenance dialysis was 34.6%. Most of the echocardiographic parameters, including end-diastolic internal diameters of the left atrium, left ventricle, right atrium, and pulmonary artery, as well as interventricular septum mobility, left ventricular posterior wall mobility, fractional shortening, stroke volume and left ventricle ejection fraction (LVEF), were associated with PH. Furthermore, Mg2+ (p = 0.037) and Cl− (p = 0.043) were significantly associated with PASP. However, after adjustments were made in the regression analysis, only internal diameters of the left atrium, right atrium, and LVEF were independently associated with PH.Conclusion: PH is prevalent, with a relatively high incidence among ESRD patients who undergo maintenance dialysis. The sizes of the left and right atria as well as LVEF were independently associated with PH, but further cohort and basic mechanistic studies are needed to confirm this finding.

<strong>Background:</strong> Acute changes in left ventricular diastolic function shortly after ASD closure in elderly patients have not been well known. We aimed to investigate acute changes in left ventricular end diastolic pressure (LVEDP) in elderly patients following transcatheter closure of atrial septal defect (ASD). <br /><strong>Methods:</strong> All 19 adults with ASDs who underwent transcatheter closure between June 2013 and December 2014 were enrolled. LVEDP was measured prior to device closure and compared with that immediately following device closure and 15 minutes after device closure. <br /><strong>Results:</strong> The median age of the patients was 48 years old. The baseline E/e’ and LVEDP values were 8.3 ± 2.8 and 13 ± 3 mmHg. The LVEDP value immediately following closure was 19 ± 4 mmHg, and 15 minutes after closure was 16 ± 4 mmHg. The median increase in the LVEDP value immediately following closure was 6 mmHg, which significantly differed from that prior to closure. The LVEDP 15 minutes after closure decreased but remained significantly higher than the value observed immediately after closure. No significant changes were observed with regard to E/e’ at either 1 day or 3 months following closure. The LVEDP value <br />15 minutes after device closure was significantly correlated with those observed before closure and immediately following closure; however, no significant correlations were observed with regard to patient age, Qp/Qs, E/e’ before closure, or E/e’ 3 months after device closure.<br /><strong>Conclusion:</strong> LVEDP in adults with ASDs significantly increases following device closure. LVEDP before closure predicts LVEDP following device closure.

Abstract Abernethy malformation is a rare entity. We report a 5-year-old boy presenting with severe pulmonary hypertension in whom Abernethy malformation and inferior caval vein interruption were diagnosed by CT angiography. In addition, the iliac veins were thrombosed with multiple venous collateral drainage. This abnormal venous anatomy caused difficulty in device closure of the Abernethy malformation, which was successfully closed using a vascular plug.

Abstract Introduction Sleep disordered breathing (SDB) is a group of ventilatory disorders during sleep which includes obstructive sleep apnea (OSA), central sleep apnea (CSA), and sleep related hypoventilation. In patients with SDB, the prevalence of pulmonary hypertension (PH) ranges from 17% to 52%. While SDB is prevalent in the general population with recent estimates of 20% to 30%, in those with cardiovascular disease, particularly left ventricular failure, there is a higher reported prevalence of 47%. Aims The aims of this study were to determine the prevalence and prognostic relevance of sleep apnea in a cohort of patients with newly diagnosed pulmonary arterial hypertension (ESC/WHO Group 1 pulmonary hypertension). Methods We evaluated prospectively 76 patients with the pulmonary arterial hypertension (mean age 54±16 years; 45% male). All patients underwent right heart catheterisation, clinical assessments, sleep study, standard laboratory testing and evaluation of subjective sleepiness by the Epworth Sleepiness Scale. Sleep test was provided with an ApneaLink Plus, consisting of nasal pressure sensor, respiratory effort band, and pulse oximeter worn on the finger. Subjects previously treated for or diagnosed with SDB were excluded from the study. Results Sleep apnea (SA) – defined as apnea-hypopnea index (AHI) ≥5/h – was found in 59 (77.6%) of the pulmonary arterial hypertension (PAH) patients. Mean AHI in the cohort of PAH patients with SA was 26.1±16.6/h. Mean follow-up was 24 months, during which 15 (19.7%) patients died. Characteristics of parameters related to SA in groups of survivors and deceased are in table 1. From the sleep apnea-related parameters, only time with O2Sat &lt;90% – T90 was significantly associated with mortality (AUC 0.856; 95% CI 0.693 – 1.019; p&lt;0.001). Conclusions The presence of sleep apnea in pulmonary arterial hypertension patients is high. The prevalence of sleep apnea is higher in PAH patients than in the general population. The presence of sleep apnea in patients with PAH was not associated with worse prognosis, but noctural hypoxemia (time with O2Sat &lt;90%) was related to poor prognosis. Sleep apnea in patients with PAH should be screened for systematically. Funding Acknowledgement Type of funding source: None
