“…The ASD closure technique did not affect the P wave in a comparison of different percutaneous techniques, or surgical repair and percutaneous techniques in previous studies 3,11. Javadzadegan et al3 suggested that in both percutaneous ASD closure and surgical treatment, the P-wave duration was decreased at six months’ follow up and this decrease was not related to the defect size.…”

“…By contrast, Thilen et al11 declared that increased P-wave duration did not decrease with surgical repair in older patients and it was not related to atrial dilatation. In haemodynamically significant ASD, the increase in P-wave duration may depend on regional damage of the atrial conduction pathways rather than atrial enlargement 12,13…”

“…The age of the patient at ASD closure may be a risk factor for the development of arrhythmia in the follow-up period 11,14. ASD repair in childhood prevents permanent changes in the atrial myocardium and regresses P max and P d , thus decreasing the risk for atrial fibrillation in older patients 2,15.…”

SummaryIntroduction:In this study we compared the effects of two different surgical procedures for closure of adult atrial septal defect (ASD) on postoperative P-wave changes.Methods:Patients who underwent cardiac surgery for secundum type ASD closure were evaluated retrospectively. Seventy-two patients with primary repair of ASD and 29 patients with pericardial patch plasty repair were compared according to Pmax, Pmin and P-wave dispersions (Pd).Results:In each group, the increases in postoperative maximum P-wave duration (Pmax) and minimum P-wave duration (Pmin) were statistically significant. There was no statistically significant difference between post- and pre-operative Pd values. In the comparison between group 1 and group 2 in terms of postoperative P-wave changes (Pmax, Pmin, Pd) there was no statistically significant difference.Conclusion:Comparing patch plasty and primary repair for the surgical closure of ASD in the early to mid-postoperative period, no difference was found and both surgical procedures can be performed in adult ASDs.

“…Many papers have focused on this issue from different aspects. These aspects included the hemodynamic status 15 as well as electrocardiographic, 16,17 functional, [18][19][20][21][22] and volumetric reverse remodeling [23][24][25][26] ; none of which have correlated remodeling to MVP status.…”

Introduction: Mitral valve prolapse (MVP) is the most common anomaly of the mitral valve. Several studies have shown prevalence of MVP in atrial septal defect (ASD) especially secundum types (II). The aims of this study is to show the potential role of 3D echocardiography in improving the diagnosis of MVP and to depict the relationship between reverse remodeling of the right and left ventricles (RV, LV) and MVP after transcatheter closure of ASD II. Methods: Sixty patients underwent transcatheter closure of ASD II and completed follow up by 2D and 3D echocardiography in Cairo University Children Hospital before the procedure and at 24 hours, 1 and 6 months after the procedure. Results: 3D echocardiography was more accurate than 2D echocardiography in detecting MVP frequency in ASD II patients (75% vs. 50%). Maximum statistically significant remodeling was detected by 3D echocardiography 1 month after the procedure (RV: LV ratio by 3D echocardiography 1.9±0.03 24 hours after the procedure vs. 1.6±0.03 1 months after the procedure, P < 0.01) while 2D echocardiography was delayed in detecting biventricular reverse remodeling. 3D derived RV: LV ratio was accurate in detecting MVP status with a sensitivity of 88%.

“…A prolonged SAECG P-wave duration was also mentioned in septal atrial defect, especially in patients who experienced AF, not corrected after atrial septal defect closure, and it was demonstrated that atrial conduction disturbances occur early, requiring an early intervention to prevent the development of late AF ( Table 2) [47].…”

Signal-averaged ECG (SAECG) is a high-resolution, noninvasive electrocardiographic method enabling detection of late ventricular potentials (LVP), which are low-amplitude and high-frequency signals, predicting reentry ventricular arrhythmias, and sudden cardiac death (SCD). Three criteria are used to detect late ventricular potentials as follows: signal-average ECG QRS duration (SAECG-QRS), the duration of the terminal part of the QRS complex with an amplitude below 40 μV (LAS40) and the root mean square (RSM) signal amplitude of the last 40 ms of the signal < 20 μV (RMS40). Late ventricular potentials can be detected not only at the end of a QRS complex but also as intra-QRS (IQRS) potentials. Signal-averaged ECG was modiied to enable the analysis of the P-wave and to detect atrial late potentials (ALPs), low-amplitude potentials at the terminal part of the iltered P-wave, and predictors of atrial ibrillation (AF). Late atrial and ventricular potentials originate from areas of delayed, fragmented, and heterogenous conduction within atrial or ventricular myocardium. This chapter reviews the most important mechanisms explaining the occurrence of late ventricular, intra-QRS, and atrial potentials; their predictive value for arrhythmia, focusing on recent clinical data, long-term follow-up, and outcome; and analysis of SAECG variables in cardiac and noncardiac diseases.
