Background—Several models have been developed to predict prolonged stay in the
intensive care unit (ICU) after cardiac surgery. However, no extensive quantitative validation …

A wide variety of risk stratification systems have been developed to quantify the risk of
cardiac surgery. Generally, the focus has been on mortality; however, more recently models …

Aims To compare 19 risk score algorithms with regard to their validity to predict 30-day and 1-
year mortality after cardiac surgery. Methods and results Risk factors for patients undergoing …

Aims Risk scores provide an important contribution to clinical decision-making, but their
validity has been questioned in patients with valvular heart disease (VHD), since current …

Objectives Two objectives were set for this study. The first was to identify factors influencing
prolonged postoperative length of stay (LOS) following cardiac surgery. The second was to …

2 Methods The ASCTS database project has prospectively collected data on patients
undergoing cardiac surgery at all six publicly funded cardiac surgical units in the state of …

BACKGROUND: Percutaneous aortic valve replacement (PAVR) trials are ongoing in
patients with an elevated European System for Cardiac Operative Risk Evaluation …

Purpose To study the feasibility of predicting fluid responsiveness (FR) by passive leg
raising (PLR) using a Bioreactance-based noninvasive cardiac output monitoring device …

Background Frailty is a risk factor for mortality, morbidity, and prolonged length of stay after
cardiac surgery, all of which are major drivers of hospitalization costs. The incremental …

Background Radical cystectomy is a standard treatment for muscle-invasive bladder cancer
but frequently entails postoperative pulmonary complications (PPCs). Nutrition is closely …
