Introduction: A scheduled catheter ablation for atrial fibrillation (AF) can be postponed due to preexisting thrombi in the left atrial appendage (LAA) identified by trans-esophageal echocardiography (TEE). We aimed to elucidate the predictive factor for thrombi formation. Methods: A total of 372 AF ablation candidates (male, 312; age, 59.8±10.4 years; CHA2DS2-VASc, 1.3±1.3; paroxysmal, 219) were evaluated. Warfarin was administered in 226 patients and dabigatran in 146 patients. A pre-procedural TEE identified thrombi in 24 patients (6.5%: postponed group). The patient background, pre-procedural blood sample data, transthoracic echocardiography (TTE), and TEE were compared between the performed and postponed groups. Results: Thu number of patients with hypertension (P=0.040), vascular disease (P<0.001), sleep apnea syndrome (P<0.001), and a TEE performed during AF (P=0.001) were significantly higher in the postponed group. The type of AF (paroxysmal, 11) and anticoagulants (warfarin, 16) did not differ between the groups. The age (P=0.007), CHA2DS2-VASc score (P=0.015), average flow velocity of the LAA measured using TEE (P<0.001), left ventricular ejection fraction (LVEF; P=0.006), size of the left atrium (LA; P=0.001) measured using TTE, and serum brain natriuretic peptide level (BNP; 82.4±81.4 pg/ml vs. 236.7±141.9; P<0.001) were significantly higher in the postponed group. The prothrombin time (P=0.087) and activated clotting time (P=0.178) did not differ. A multivariate analysis adjusted for the confounding factors such as the age, CHA2DS2-VASc score, LAA flow velocity, LA size and LVEF revealed that a serum BNP level of >135 pg/ml was the independent predictive factor for LAA thrombi (odds ratio, 14.178; 95% confidence interval [CI], 2.907 to 69.149; P=0.001). The area under the receiver operating characteristic (ROC) curve (AUC) for predicting a thrombus with the serum BNP level was 0.860 (95% CI: 0.775 to 0.944). The sensitivity and specificity for predicting a thrombus with a BNP value of >135 pg/ml were 81.8% and 83.6%, respectively. Conclusions: A serum BNP level of >135 pg/ml might be a noninvasive predictive factor for LAA thrombi in AF patients under anticoagulation therapy with warfarin and dabigatran.

Background: Brain natriuretic peptide is a cardiac hormone secreted from the left ventricular myocardium due to ventricular expansion and volume overload. A recent study shows that small VSD will have risk of ventricular dysfunction in adulthood. Another complications such as endocarditis, congestive heart failure, aortic regurgitation, arrhythmia also we should be aware. Evaluations of the plasma B-type natriuretic peptide level (NT pro BNP) are currently being considered as methods to identify the possible presence of ventricular dilation in small VSD. Objective: To evaluate the change in plasma B-type natriuretic peptide after transcatheter closure of VSD. Methods: A pretest-posttest design was conducted on VSD patients before and after transcatheter closure. Plasma B-type natriuretic peptide level were measured before and 30 days after the transcatheter closure of VSD. Result: A total of 32 peri membranous VSD patients were included in this study with 62.5 % female patients (n=20) and 37.5 % male patients (n=12). A significant decrease was observed in the median NT pro BNP level when the level before closure of 1.08 (0.74 – 3.47) ng/ml was compared to the level after closure of 0.91 (0.68 – 2.07) ng/ml (p<0.05). Conclusion: Significant decreases in NT pro BNP level are seen in small VSD patients 30 days after transcatheter closure. Patients with small peri membranous VSD are generally considered to need occlusion for their childhood defect.

Background Many studies in adult patients with systemic lupus erythematosus (SLE) have demonstrated that myocardial dysfunction was significantly associated with enhanced disease activity. However, similar studies in paediatric patients with SLE are limited. The aim of this study was to evaluate the role of speckle tracking echocardiography (STE) to detect left ventricular dysfunction in children with active and inactive SLE. Methods This prospective case–control study was carried out on 50 children with SLE. Thirty healthy age- and sex-matched children comprised the control group. The patients were further subdivided into two subgroups: active SLE and inactive SLE. Laboratory investigations undertaken included complete blood count, renal function, C3, C4, ANA, anti-dsDNA and serum N-terminal pro-B type natriuretic peptide. Echocardiographic examinations were performed on all children and included conventional echocardiography, tissue Doppler imaging (TDI) and two- and three-dimensional STE. Results There was no statistically significant difference in N-terminal pro B natriuretic peptide between the studied groups. The myocardial performance index by TDI was statistically significantly higher in SLE patients compared to controls. STE parameters were statistically significantly lower in SLE patients compared to controls. There was no correlation between STE parameters and disease activity. Conclusions STE could be a promising technique in the early detection of subclinical left ventricular dysfunction in children with SLE.
