United Kingdom standards for non-invasive cardiac imaging: recommendations from the Imaging Council of the British Cardiovascular Society.

Heart and circulatory diseases affect more than seven million people in the UK. Non-invasive cardiac imaging is a critical element of contemporary cardiology practice. Progressive improvements in technology over the last 20 years have increased diagnostic accuracy in all modalities and led to the incorporation of non-invasive imaging into many standard cardiac clinical care pathways.

Cardiac surgery and congenital heart disease: reflections on a modern revolution.

The success of cardiac surgery has transformed the prospects of children with congenital heart disease with over 90% now surviving to adulthood. The early pioneering surgeons took on significant risk, whilst current surgical practice emphasises safety and consistency. In this article we review important British contributions to the field and consider challenges for the future, specifically how to better manage and reduce the adverse sequelae of congenital cardiac surgery by continuing to innovate safely.

The NHS Five Year Forward View: implications for clinicians.

The Five Year Forward View is a look at what the NHS could achieve, given the range of resources that may be available. It sets out how the health service needs to change, arguing for a more engaged relationship with patients, carers, and citizens to promote wellbeing and prevent ill health. Here, we outline how the Forward View supports clinicians to provide better, higher quality and more integrated care.

The European Association for Cardio-Thoracic Surgery (EACTS) database: an introduction.

Objectives: Continuous monitoring of surgical outcomes through benchmarking and the identification of best practices has become increasingly important. A structured approach to data collection, coupled with validation, analysis and reporting, is a powerful tool in these endeavours. However, inconsistencies in standards and practices have made comparisons within and between European countries cumbersome.

The development of a postoperative morbidity score to assess total morbidity burden after cardiac surgery.

Objective: To develop a tool for identifying and quantifying morbidity following cardiac surgery (cardiac postoperative morbidity score [C-POMS]).

Study Design And Setting: Morbidity was prospectively assessed in 450 cardiac surgery patients on postoperative days 1, 3, 5, 8, and 15 using POMS criteria (nine postoperative morbidity domains in general surgical patients) and cardiac-specific variables (from expert panel). Other morbidities were noted as free text and included if prevalence was more than 5%, missingness less than 5%, and mean expert-rated severity-importance index score more than 8.

Tissue oxygen saturation and outcome after cardiac surgery.

Background: Cardiopulmonary bypass during cardiac surgery can result in a shortfall in oxygen delivery relative to demand, marked by a decrease in muscle tissue oxygen saturation as blood flow is redistributed to vital organs. Such "tissue shock" might impair postoperative recovery.

Objectives: To determine the association of changes in tissue oxygen saturation with postoperative outcome in cardiac surgery patients.

Patient-prosthesis mismatch in patients with aortic stenosis undergoing isolated aortic valve replacement does not affect survival.

Background: Data suggest that patient-prosthesis mismatch (PPM) adversely effects late survival after aortic valve replacement (AVR). This study examined the incidence and implications of PPM in patients undergoing isolated AVR.

Methods: Prospectively collected data on patients undergoing isolated AVR for aortic stenosis between January 1, 1997 and December 31, 2007 were analyzed.

Assessing the cost effectiveness of using prognostic biomarkers with decision models: case study in prioritising patients waiting for coronary artery surgery.

Objective: To determine the effectiveness and cost effectiveness of using information from circulating biomarkers to inform the prioritisation process of patients with stable angina awaiting coronary artery bypass graft surgery.

Design: Decision analytical model comparing four prioritisation strategies without biomarkers (no formal prioritisation, two urgency scores, and a risk score) and three strategies based on a risk score using biomarkers: a routinely assessed biomarker (estimated glomerular filtration rate), a novel biomarker (C reactive protein), or both. The order in which to perform coronary artery bypass grafting in a cohort of patients was determined by each prioritisation strategy, and mean lifetime costs and quality adjusted life years (QALYs) were compared.
