The Impact

Abstract Background Limited information has been reported regarding the impact of percutaneous mitral valve repair (PMVR) on ventricular arrhythmic (VA) burden. The aim of this study was to address the incidence of VA and appropriate antitachycardia implantable cardiac defibrillator (ICD) therapies before and after PMVR. Methods We retrospectively analyzed all consecutive patients with heart failure with reduce left ventricular ejection fraction, functional mitral regurgitation grade 3+ or 4+ and an active ICD or cardiac resynchronizer who underwent PMVR in any of the eleven recruiting centers. Only patients with complete available device VA monitoring from one-year before to one year after PMVR were included. Baseline clinical and echocardiographic characteristics were collected before PMVR and at 12-months follow-up. Results 93 patients (68.2±10.9 years old, male 88.2%) were enrolled. PMVR was successfully performed in all patients and device success at discharge was 91.4%. At 12-months follow-up, we observed a significant reduction in mitral regurgitation severity, NT-proBNP and prevalence of severe pulmonary hypertension and severe kidney disease. Patients also referred a significant improvement in NYHA functional class and showed a non-significant trend to reserve left ventricular remodeling. After PMVR a significant decrease in the incidence of non-sustained ventricular tachycardia (VT) (5.0–17.8 vs 2.7–13.5, p=0.002), sustained VT or ventricular fibrillation (0.9–2.5 vs 0.5–2.9, p=0.012) and ICD antitachycardia therapies (2.5–12.0 vs 0.9–5.0, p=0.033) were observed. Conclusion PMVR was related to a reduction in arrhythmic burden and ICD therapies in our cohort. Proportion of patients who presented ven Funding Acknowledgement Type of funding source: None

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.

Purpose: This study examined the clinical significance of N-terminal pro brain natriuretic peptide level as a cardiac marker in Japanese hemodialysis patients. Methods: This was a multicenter cross-sectional study involving 1428 Japanese hemodialysis patients. Ultrasonic cardiography data at post-hemodialysis were obtained from 395 patients. We examined whether serum N-terminal pro brain natriuretic peptide levels were associated with cardiac parameters and assessed cut-off values and investigated factors associated with a reduced ratio of N-terminal pro brain natriuretic peptide levels pre- and post-hemodialysis. Results: Multivariate logistic regression analysis showed that pre- and post-hemodialysis N-terminal pro brain natriuretic peptide levels were associated with left ventricular hypertrophy on electrocardiogram (odds ratio: 3.10; p < 0.001 at pre-hemodialysis and odds ratio: 2.70; p < 0.001 at post-hemodialysis) and left ventricular hypertrophy on ultrasonic cardiography (odds ratio: 3.06; p < 0.001 at pre-hemodialysis and odds ratio: 3.15; p < 0.001 at post-hemodialysis). Post-N-terminal pro brain natriuretic peptide levels were also significantly associated with ejection fraction on urine chorionic gonadotrophin (ultrasonic cardiography; odds ratio: 35.83; p < 0.001). Receiver operating characteristic curves for predicting the presence of left ventricular hypertrophy on electrocardiogram and ultrasonic cardiography showed similar sensitivity (57.7%, 57.3% at pre-hemodialysis and 63.9%, 48.2% at post-hemodialysis) and specificity (66.5%, 72.9% at pre-hemodialysis and 59.2%, 81.9% at post-hemodialysis). Decreased ejection fraction on ultrasonic cardiography showed better sensitivity (78.6%) and specificity (88.7%). The N-terminal pro brain natriuretic peptide reduction ratio during a hemodialysis session correlated with Kt/V, membrane area, membrane type, modality, body weight gain ratio, treatment time, and ultrafiltration rate with multiple linear regression ( R: 0.53; p < 0.001 except for ultrafiltration rate ( p = 0.003)). Conclusion: Both pre- and post-hemodialysis N-terminal pro brain natriuretic peptide are associated with the presence of left ventricular hypertrophy in this population. The post-hemodialysis N-terminal pro brain natriuretic peptide level is a useful marker for systolic dysfunction.
