Association between cumulative blood pressure in early adulthood and right ventricular structure and function in middle age: The CARDIA study.

Objective: Cumulative blood pressure (BP) exposure is a known risk factor for cardiovascular disease. This study sought to investigate the association between cumulative BP from early adulthood to middle age and right ventricular (RV) structure and function in middle age.

Methods: We included 2844 participants from the CARDIA study (Coronary Artery Risk Development in Young Adults).

Automated Facial Recognition for Noonan Syndrome Using Novel Deep Convolutional Neural Network With Additive Angular Margin Loss.

Background: Noonan syndrome (NS), a genetically heterogeneous disorder, presents with hypertelorism, ptosis, dysplastic pulmonary valve stenosis, hypertrophic cardiomyopathy, and small stature. Early detection and assessment of NS are crucial to formulating an individualized treatment protocol. However, the diagnostic rate of pediatricians and pediatric cardiologists is limited.

Catheter Ablation of Ventricular Arrhythmias Originating From the Pulmonary Sinus Cusp in Pediatric Patients: A Single-Center Retrospective Study.

There are few reports of ventricular arrhythmias (VAs) originating from the pulmonary sinus cusp (PSC) in pediatric patients. Thus, we investigated the ablation of PSC-VAs in pediatric patients. Clinical, echocardiographic, and ablation data were reviewed in 10 consecutive symptomatic children who underwent successful ablation of VAs of PSC origin at our center between March 2014 and June 2018.

Experimental, Pathologic, and Clinical Findings of Radiofrequency Catheter Ablation of Para-Hisian Region From the Right Ventricle in Dogs and Humans.

Background: Ablation of para-Hisian accessory pathway (AP) poses high risks of atrioventricular block. We developed a pacing technique to differentiate the near-field (NF) from far-field His activations to avoid the complication.

Methods And Results: Three-dimensional mapping of the right ventricle was performed in 15 mongrel dogs and 23 patients with para-Hisian AP.

Electrophysiological and electrocardiographic predictors of ventricular arrhythmias originating from the left ventricular outflow tract within and below the coronary sinus cusps.

Aims: Ventricular arrhythmias (VAs) from the left ventricular outflow tract (LVOT) can originate from within or below the aortic sinus of valsalva (ASV). Mapping and ablation below the ASV is challenging and there are limited data predicting VA origins using electrocardiographic and electrophysiological features.

Methods: Thirty-four patients (56.

[Short-and mid-term outcomes of transcatheter intervention for critical pulmonary stenosis and pulmonary atresia with intact ventricular septum in neonates].

Objective: To assess the safety and efficacy of transcatheter intervention for critical pulmonary stenosis (CPS) and pulmonary atresia with intact ventricular septum (PA/IVS) in neonates.

Method: From June 2006 to September 2011, 27 neonates including CPS in 19 patients and PA/IVS in 8 patients underwent transcatheter intervention. All patients had membranous stenosis or atresia without severe Ebstein's anomaly and severe right ventricle and pulmonary valve hypoplasia, without right ventricle-dependent coronary circulation in PA/IVS.
