Prediction of in-hospital death following aortic valve replacement: a new accurate model.
OBJECTIVES Aortic valve replacement (AVR) is accepted as the standard treatment for severe symptomatic aortic valve stenosis and regurgitation. As novel treatments are introduced for patients at high risk for conventional surgery, it is important to have models that accurately predict procedural risk. The aim of this study was to develop and validate a risk-stratification model to predict in-ho...
متن کاملTranscatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملA multi-centre additive and logistic risk model for in-hospital mortality following aortic valve replacement.
OBJECTIVE To develop a multivariate prediction model for in-hospital mortality following aortic valve replacement. METHODS Retrospective analysis of prospectively collected data on 4550 consecutive patients undergoing aortic valve replacement between 1 April 1997 and 31 March 2004 at four hospitals. A multivariate logistic regression analysis was undertaken, using the forward stepwise techniq...
متن کاملAn Australian risk prediction model for determining early mortality following aortic valve replacement.
OBJECTIVE To develop a multivariable logistic risk model for predicting early mortality following aortic valve replacement (AVR) in adults, and to compare its performance against existing AVR-dedicated models. METHODS Prospectively collected data from the Australasian Society of Cardiac and Thoracic Surgeons (ASCTS) database project were used. Thirty-five preoperative variables from AVR liter...
متن کاملCoronary artery spasm following aortic valve replacement.
The authors present a clinical case of coronary artery spasm in a 62-year-old woman undergoing elective aortic valve replacement surgery for aortic regurgitation. On admission at ICU, the patient developed marked hemodynamic and electrical instability. Emergent coronary angiography demonstrated a pronounced spasm of the distal portion of the right coronary artery, apparently related to compress...
