Multicenter StudyDiagnostic role of coronary calcium scoring in the rapid access chest pain clinic: prospective evaluation of NICE guidance.
Coronary artery calcium (CAC) imaging by unenhanced computed X-ray tomography (CT) is recommended as an initial diagnostic test for patients with stable chest pain symptoms but a low likelihood (10-29%) of underlying obstructive coronary artery disease (CAD) after clinical assessment. The recommendation has not previously been tested prospectively in a rapid access chest pain clinic (RACPC). ⋯ Patients with stable chest pain symptoms but a low likelihood of CAD can safely be diagnosed as not having obstructive CAD in the absence of detectable coronary calcification by unenhanced CT. Patients with CAC >400 Au have a high prevalence of obstructive CAD and further investigation with ICA or functional imaging may be warranted rather than CTCA. These findings support NICE guidance for the investigation of stable chest pain. ClinicalTrials gov identifier: NCT01464203.

ReviewThe year 2013 in the European Heart Journal--Cardiovascular Imaging: Part II.
The new multi-modality cardiovascular imaging journal, European Heart Journal - Cardiovascular Imaging, was created in 2012. Here we summarize the most important studies from the journal's second year in two articles. Part I of the review has summarized studies in myocardial function, myocardial ischaemia, and emerging techniques in cardiovascular imaging. Part II is focussed on valvular heart diseases, heart failure, cardiomyopathies, and congenital heart diseases.

Rescue transoesophageal echocardiography for refractory haemodynamic instability during transvenous lead extraction.
The rising number of cardiovascular implantable electronic devices has led to a steep increase in transvenous lead extractions (TLEs). Procedure-related, haemodynamically significant adverse events are uncommon during TLE yet remain an inevitable risk. While the use of transoesophageal echocardiography (TEE) as a guide to clinical decision-making during refractory circulatory instability has been well established, the specific utility of rescue TEE during TLE has not been comprehensively studied. ⋯ While TLE is a relatively safe procedure, life-threatening cardiovascular injuries remain a rare risk. In this study, the use of rescue TEE ruled out significant cardiovascular injuries in the majority of patients. Furthermore, rescue TEE had a substantial impact on the efficiency of determining the aetiology of refractory haemodynamic instability during TLE and thereby facilitated the timely initiation of definitive intervention.
