PP-145 The Effect of Percutaneous Closure of Atrial Septal Defects on the P Wave Dispersion
MARCH 26e29, 2015 Results: The study population consisted of heart failure patients(64.012.7 years). We found statistically significant correlation between LVM, LVMI, RWT and EPSS(p<0.001 for all)(Table). Conclusions: Both EPSS and LVMI may reflect outcomes of patient. We detected interestingly relation between these two parameters. We are needed to run clinical studies on larger patient groups for these relations to confirm the results.

Objective: The aim of this study is to assess the P-wave dispersion (Pd) in patients who underwent percutaneous ASD closure devices, to determine the effects of structural innovations on atrial electrical inhomogeneity. Methods: We prospectively examined 22 consecutive patients who underwent percutaneous transcatheter closure of secundum ASD from June 2013 to December 2014. P wave maximum, P wave minimum, and P wave dispersion were measured with 12-lead surface electrocardiography, before the procedure and soon after procedure.SPSS 12 was used for statistical analysis. Results: A total of 22 patients were prospectively evaluated; 5 male and 17 females. The mean age of the patients was 36.3 9.2 years. The mean diameter of the occlusive devices was 18.3 7.2 mm. Pmax, Pmin and Pd were significantly increased immediate after procedure (p<0.05). Before percutaneous ASD closure; Pmax: 79.84.1 ms, Pmin: 42.33.7 ms, Pd: 37.22.7 ms. Immediate after percutaneous ASD closure; Pmax: 95.34.3 ms, Pmin: 48.73.9 ms, Pd: 48.33.6 ms (p<0.05). Conclusions: Pmax, P min and Pd were significantly increased soon after atrial septal defect closure procedure in percutaneous closure of secundum ASD. Key words: Transcatheter closure, arrhythmia, atrial septal defect.

Assesment of Left Ventricular Myocardial Performance Index in Patients Who Underwent Percutaneous ASD Closure Devices. Onder Ozturk1, Unal Ozturk2. 1 Department of Cardiology, Diyarbakir Gazi Yasargil Education and Research Hospital, Diyarbakır, Turkey; 2 Department of Neurology, Dicle University Medicine Faculty, Diyarbakir, Turkey. Objective: Echocardiographic measurement of left ventricular function in patients with atrial septal defect (ASD) is challenging. The Doppler myocardial performance index (MPI) may provide a method of assessing function in these patients. The aim of this study was to evaluate left ventricular (LV) function and its changes after transcatheter closure in patients with ASD using MPI by tissue Doppler imaging (TDI). Methods: We prospectively examined 22 consecutive patients who underwent percutaneous transcatheter closure of secundum ASD from June 2013 to December 2014. MPI defined as the sum of isovolumic relaxation and isovolumic contraction time divided by ejection time, was measured by tissue Doppler imaging Measurement of time intervals and MPI with TDI were performed in 22 patients with ASD before closure, and 1 month after closure. SPSS 12 was used for statistical analysis. Results: A total of 22 patients were prospectively evaluated; 5 male and 17 females. The mean age of the patients was 36.3 9.2 years. The mean diameter of the occlusive devices was 18.3 7.2 mm.The LV MPI obtained by TDI decreased markedly after percutaneous closure of secundum ASD than before percutaneous closure of secundum ASD (TDI: 0.36 0.09 vs. 0.32 0.07, p > 0.05). Conclusions: There was no significant difference of LV MPI before and after percutaneous closure of secundum ASD.

Objectives: Heart rate variability (HRV) measures are altered in various cardiac and non-cardiac situations. Aim of this study was to assess HRV parameters in patients with a percutaneous atrial septal defect (ASD) closure.
Variables
Methods: A total of 22 patients who had undergone percutaneous closure of secundum ASD. Twenty-four-hour ambulatory electrocardiographic recordings were obtained before and 1 month after percutaneous closure of secundum ASD. The five time-domain (SDNN, SDANN, rMSSD, PNN50, and mean RR) indices of HRV were analyzed. Results: A significant decrease in calculated HRV variables was observed before percutaneous closure of secundum ASD than after percutaneous closure of secundum ASD (Table 1). Conclusions: Our results indicate that percutaneous closure of secundum ASD improve HRV parameters.

Pediatric Atrial Septal Defect Closure Under General Anesthesia.

Aims: Atrial septal defects (ASD) are present in about 1 in 1,500 children at birth and account for 30% to 40% of congenital heart disease in adults. ASD closure is usually performed for the prevention of stroke or right ventricular volume overload and pulmonary hypertension. Current American Heart Association guidelines recommend closure of ASDs for right atrial or right ventricular enlargement, paradoxic embolism, documented orthodeoxiaplatypnea and pulmonary hypertension. ASD closure results in symptomatic improvement and reductions in right ventricular size and pulmonary arterial pressures at any age.
