The Patient Selection Criteria For Veno-Arterial Extracorporeal Mechanical Oxygenation, Sandeep Banga, Abhiram Challa, Avani R. Patel, Shantanu Singh, Vamsi K. Emani

Faculty & Staff Scholarship

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) plays a crucial role in the management of patients with refractory cardiac and pulmonary dysfunction by providing temporary mechanical hemodynamic and respiratory support. However, the paucity of guidelines on indications for administering it and the failure to timely initiate VA-ECMO often result in a high in-hospital mortality rate and poor six-month outcomes after VA-ECMO deployment. Due to ethical issues, randomized controlled studies with VA-ECMO have not been conducted so that no recommended evidence-based guidelines exist for VA-ECMO patientselection criteria. Therefore, the indication for administering the device depends solely on expert opinion after reviewing the literature. …

Conduction Abnormalities After Transcatheter Aortic Valve Replacement, S. Kanjanauthai, K. Bhasin, L. Pirelli, C. A. Kliger

Journal Articles

© RADCLIFFE CARDIOLOGY 2019 Transcatheter aortic valve replacement (TAVR) has been established as a therapeutic option for patients with severe symptomatic aortic stenosis who are of intermediate or higher surgical risk. Several periprocedural complications are reduced with newer transcatheter heart valve generations; however, conduction abnormalities and the need for permanent pacemaker implantation have remained unchanged and are the most frequent TAVR complications. The close relationship of the atrioventricular node and left bundle branch to the subaortic region explains these potential conduction abnormalities. This article highlights conduction abnormalities after TAVR with a focus on basic conduction system anatomy in relation to …

Aims There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after 'recalibration', a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied. Methods and results Using individual-participant data on 360 737 participants without CVD at baseline in 86 prospective studies from 22 countries, we compared the Framingham risk score (FRS), Systematic COronary Risk Evaluation (SCORE), …

Implementing A Discharge Navigator Reducing 30-Day Readmissions For Heart Failure And Sepsis Populations, Karen Weeks

Doctor of Nursing Practice (DNP) Final Clinical Projects, 2016-2019

A national focus for healthcare reform is preventing hospital readmissions. Thirty-day unplanned hospital readmissions impact patient outcomes and are costly to the healthcare system. This project explored the impact between the discharge navigator and 30-day unplanned readmissions for heart failure and sepsis populations in a 238-bed community hospital located in central Virginia. The primary aim of this discharge navigator project was to reduce 30-day readmissions for the heart failure and sepsis populations to meet the goals of the top quartile for like hospitals and the evaluation of cost avoidance for these readmissions. Heart failure and sepsis populations are high risks …

Methods: We identified 573 CORAL subjects with complete baseline data and the presence or absence of a composite endpoint for the study. These data were subjected to several models including a generalized linear (logistic-linear) model, support vector machine, decision tree, feed-forward neural network, and random forest, in an effort to attempt to predict the composite endpoint. The subjects were arbitrarily divided into training and testing subsets according …

Choosing Catheter Sheath Introducers In Infants-Information You Are Not Provided But Should Have!, Christopher Mathis, Ryan Romans, Abhay Divekar

Posters

Background: The advertised catheter sheath introducer (CSI) size, the internal diameter (ID), defines the maximum size of medical devices that can pass through it. However, the outer diameter (OD) determines the risk of vascular injury, varies considerably between manufacturers, and is not advertised. The highest risk of vascular injury is in infants less than one year of age and 3 - 6Fr CSIs are typically used.

Methods: The OD of 3, 3.3, 4, 5, and 6F CSIs (5 of each size) from different manufacturers were measured using a Mitutoyo Digital Micrometer. CSIs were measured with the dilator in place. Three …
