OBJECTIVES There remains a paucity of mechanistic data on the effect of transcatheter aortic valve implantation (TAVI) on early left and right ventricular function and quantitative aortic valve regurgitation. We sought to assess and compare the early effects on myocardial function and aortic valve hemodynamics of TAVI and aortic valve replacement (AVR)… (More)
Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement is a known complication associated with poorer outcomes. This article discusses the current techniques for assessing the severity of PVR, including angiography, hemodynamics, MRI, and echocardiography. The strengths and pitfalls of each modality are reviewed.
PURPOSE Right ventricular (RV) systolic function as measured by right ventricular ejection fraction (RVEF) has long been recognized as an important predictor of outcome in heart failure patients. The echocardiographic measurement of RV volumes and RVEF is challenging, however, owing to the unique geometry of the right ventricle. Several nonvolumetric… (More)
AIMS The aims of this study were (1) to evaluate the relationship between novel two-dimensional transthoracic indices of left atrial (LA) mechanical function (speckle-tracking- and tissue Doppler-derived parameters), conventional indices (A-wave peak velocity and velocity-time integral, and A' velocity), and transoesophageal echocardiographic parameters (LA… (More)
This prospective study is designed to identify novel imaging (utilizing cardiovascular magnetic resonance and advance echocardiography) and biochemical markers to detect early, sub-clinical cardiotoxicity following chemotherapy.
We are reporting a case of 66 year-old man who presented to a regional hospital with sudden onset of inter-scapular pain, radiating to anterior chest. Initial assessment was unremarkable except for high blood pressure and computed tomography (CT) of chest showing an intramural haematoma in the thoracic descending aorta. He was transferred to our institution… (More)
