Abstract There are minimal data regarding chronic management of single‐ventricle ventricular assist device (VAD) patients. This study aims to describe our center's multidisciplinary team patients supported long term with the Berlin Heart EXCOR Pediatric VAD. Patient #1 was a 4‐year‐old double‐outlet right ventricle aortic atresia, L‐looped ventricles, and heart block who developed failure 1 year after Fontan. She initially required extracorporeal membrane oxygenation support transitioned...

Objectives The objective was to review the use of Impella devices (Abiomed Inc, Danvers, MA) for temporary circulatory support in pediatric and adolescent patients (age ≤ 21 yrs). Background Options minimally invasive children are limited, published data confined case reports small series. Methods This a retrospective, multicenter implants from 2009‐15, using standardized collection INTERMACS definitions. Results A total 39 were performed 38 16 centers. Median age weight yrs (4–21 yrs) 62 kg...

Abstract The objective of this study was to evaluate a new technique sizing atrial septal defects (ASDs) for transcatheter device closure. ASD closure using the Amplatzer occluder (ASO) is commonly performed. Complications, including arrhythmias, pericardial effusions, and perforations, may be related oversizing ASDs choosing larger devices. Two methods were used size compliant balloon. In some patients, balloon inflated until waist visible [(+)waist]; in others, only no shunting...

Background There are limited mechanical circulatory support options for patients with single ventricle (SV) anatomy. This is a multicenter, retrospective study of the Impella pump to systemic in cohort SV Fontan circulation. Methods Patients anatomy supported an device from 2012 2015 were included. Demographic information, indication support, adverse events and short‐term outcome data collected. Results Ten The median age weight at implant was 26 years (4‐38 years) 64 kg (15–102 kg)....

Percutaneous circulatory support is widely available for use in adult patients. Options remain limited the pediatric population due to limitations of vessel and patient size, resulting more invasive means support. We present a case series patients whom Impella 2.5 axial flow pump was able be placed utilizing hybrid approach that allowed adequate distal perfusion while providing successful short‐term hemodynamic © 2013 Wiley Periodicals, Inc.

Objective Acute kidney injury (AKI) is a common complication resulting from cardiopulmonary bypass in infants. Urinary neutrophil gelatinase-associated lipocalin (NGAL) sensitive and specific marker of such injury. In this study, we compared the performance serum cystatin C (Cys C) creatinine (Cr) as early markers renal dysfunction infants undergoing cardiac surgery under bypass.

Abstract Novel commercially available software has enabled registration of both CT and MRI images to rapidly fuse with X-ray fluoroscopic imaging. We describe our initial experience performing cardiac catheterisations the guidance 3D imaging overlay using VesselNavigator system (Philips Healthcare, Best, NL). A total 33 patients CHD were included in study. Demographic, advanced imaging, catheterisation data collected between 1 December, 2016 31 January, 2019. report successful use this...

To determine whether contrast administration was a risk factor for development of acute kidney injury (AKI) in cyanotic congenital heart disease (CHD) patients undergoing cardiopulmonary bypass (CPB).AKI following CPB or is well described. In previous studies, prior to has been shown increase the AKI. Chronic cyanosis leads glomerular damage and dysfunction, thus potentially placing this population at increased developing AKI CPB.One hundred twenty-two with CHD preoperative cardiac...
