The prevalence of atrial fibrillation (AF) is increasing in parallel with an ageing population leading to increased morbidity and mortality. The most feared complication of AF is stroke, with the arrhythmia being responsible for up to 20% of all ischemic strokes. An important contributor to this increased risk of stroke is the left atrial appendage (LAA). A(More)
We report a series of 4 cases of transcatheter aortic valve replacement infective endocarditis from our institution. Atypical diagnostic features were noted echocardiographically. Infection with enterococcal species was prevalent and a coexisting mitral valve vegetation was found in 2 patients. All 4 patients had excellent responses to intravenous(More)
BACKGROUND Trans-catheter aortic valve implantation (TAVI) is now a well recognised procedure for the high risk surgical patient with native or bioprosthetic aortic valve stenosis. Transfemoral and transapical implantation techniques are well described. With increasing referral of more marginal transapical patients, we describe our experience of a(More)
BACKGROUND There is little data regarding the demographic profile of young (<45 years) Australian acute coronary syndrome patients. The aim of this study was to compare baseline characteristics, risk factor profile and outcomes of young patients compared with their older counterparts referred to two metropolitan Queensland hospitals. METHODS Over a(More)
AIMS The clinical value of optimising implant angles during transcatheter aortic valve replacements (TAVR) remains undefined. The Aortic Valve Guide (AVG) is a proprietary software that provides structured analysis of three-dimensional images from rotational angiography (DynaCT). This study compares AVG with preprocedural multislice computed tomography(More)
BACKGROUND Transcatheter aortic valve replacement (TAVR) patients are at a high risk of acute kidney injury (AKI). This study aimed to investigate AKI and the relationship with iodinated contrast media (ICM), whether there are significant pre- or peri- procedural variables predicting AKI, and whether AKI impacts on hospital length of stay and mortality.

One of the most troublesome complications of percutaneous coronary intervention (PCI) or angiography is retrograde dissection of the artery into the aortic root. We report a case involving the right coronary artery (RCA) which was treated with prompt deployment of stents. Recurrent chest pain and ST segment elevation in V(2-4) mimicked the ECG appearance of(More)
INTRODUCTION Profiling the Aortic root perpendicular to the fluoroscopic image plane will achieve a more successful implant position for trans-catheter aortic valve replacement (TAVR). This study aimed to investigate whether the divergent nature of the X-ray beam from the C-arm altered the appearance of the TAVR device. METHODS Under bench-top testing, a(More)
