A novel cardiovascular magnetic resonance risk score for predicting mortality following surgical aortic valve replacement.

The increasing prevalence of patients with aortic stenosis worldwide highlights a clinical need for improved and accurate prediction of clinical outcomes following surgery. We investigated patient demographic and cardiovascular magnetic resonance (CMR) characteristics to formulate a dedicated risk score estimating long-term survival following surgery. We recruited consecutive patients undergoing CMR with gadolinium administration prior to surgical aortic valve replacement from 2003 to 2016 in two UK centres.

Diagnostic performance of image navigated coronary CMR angiography in patients with coronary artery disease.

Background: The use of coronary MR angiography (CMRA) in patients with coronary artery disease (CAD) remains limited due to the long scan times, unpredictable and often non-diagnostic image quality secondary to respiratory motion artifacts. The purpose of this study was to evaluate CMRA with image-based respiratory navigation (iNAV CMRA) and compare it to gold standard invasive x-ray coronary angiography in patients with CAD.

Methods: Consecutive patients referred for CMR assessment were included to undergo iNAV CMRA on a 1.

Whole-heart coronary MR angiography using image-based navigation for the detection of coronary anomalies in adult patients with congenital heart disease.

Background: The purpose of this study was to evaluate a recently developed two-dimensional (2D) image-based navigation approach (iNAVG+C ) combined with respiratory bellows gating for CMRA in patients with congenital heart disease.

Methods: Nine healthy volunteers (mean age 32 ± 6 years [standard deviation]) and 29 patients (28 ± 9 years) were scanned on a 1.5 Tesla clinical scanner using iNAV(G+C) motion compensated T2prepared CMRA, and the conventional 1D NAV approach.

Triple, simultaneous, very late coronary stent thrombosis.

Coronary artery stent thrombosis is an uncommon but potentially catastrophic complication. The risk of very late stent thrombosis (VLST) raises important safety issues regarding the first generation of drug-eluting stents (DES). Although several complex mechanisms for VLST have been suggested and various predictors have been described, its pathophysiology is not completely understood and it is not known whether longer-term dual antiplatelet therapy reduces the risk.

The importance of multimodality cardiac imaging: Echocardiography and cardiovascular magnetic resonance imaging contributions to the diagnosis and management of a right ventricular mass.

Cardiac metastases from testicular tumors are rare. We report a case of a 42-year-old man with a cardiac mass incidentally found in a computed tomography-scan included in the workup for lumbago and a suspicious neoformation in the right testicle. Transthoracic echocardiography showed a large multilobular ill-defined mass infiltrating the right ventricle free wall, protruding to, and partially obstructing the right ventricular outflow tract resulting in considerable outflow obstruction.

Complex ventricular septal rupture with dissection of the right ventricular wall in ischemic context.

A 72-year-old man was admitted to the local hospital with non-ST elevation myocardial infarction. In the first 24 hours, a new onset apical murmur was heard. Transthoracic and transesophageal echocardiography showed interventricular septal (IVS) rupture and dissection of the right ventricle (RV) wall forming an echolucent pseudocavity that partially occupied the RV and communicated with the true RV cavity.
