BACKGROUND Amphetamine-associated cardiomyopathy (AAC) is becoming an increasingly recognised entity. The characteristics and outcomes of these patients are poorly understood. METHODS Thirty patients admitted with heart failure and echocardiographic evidence of cardiomyopathy between 2005 and 2014 and who had a documented history of amphetamine abuse that(More)
Echocardiography is the principal non-invasive tool for initial evaluation and longitudinal monitoring of patients with significant valvular heart disease. However echocardiography can be limited by poor acoustic windows, and is dependent on the skill and experience of the sonographer. Cardiovascular magnetic resonance (CMR) can provide a comprehensive(More)
BACKGROUND Few data exist on the relation of the 3-dimensional morphology of mitral valve and degree of mitral regurgitation (MR) in mitral valve prolapse. METHODS AND RESULTS Real-time 3-dimensional transesophageal echocardiography of the mitral valve was acquired in 112 subjects, including 36 patients with mitral valve prolapse and significant MR (≥3+;(More)
An 85-year-old man with history of hypertension presented with fever, cough and abdominal pain. Unfortunately fever and leukocytosis persisted despite treatment. Blood cultures obtained on admission grew Salmonella enteritidis. Subsequently he developed increasing back pain and transoesophageal echocardiography (TOE) was performed, demonstrating a complex(More)
BACKGROUND Apical ballooning syndrome (ABS) mimics myocardial infarction but is characterised by transient left ventricular (LV) dysfunction without significant coronary artery obstruction. METHODS We prospectively identified 100 consecutive patients presenting in the Auckland region between March 2004 and July 2010 and obtained clinical, laboratory,(More)
INTRODUCTION In functional mitral regurgitation (FMR), effective regurgitant orifice area (EROA) displays a dynamic pattern. The impact of dynamic changes of annulus dysfunction and leaflets tenting on phasic EROA was explored with real-time three-dimensional transesophageal echocardiography (RT3D-TEE). METHODS RT3D-TEE was performed in 52 FMR patients(More)
Coronary artery septic embolisation resulting in cardioembolic myocardial infarction (MI) is a rare complication of bacterial infective endocarditis (IE), representing <1% of complications related to IE. Diagnosis requires a combination of high clinical suspicion, coronary angiography, echocardiography and cultures of peripheral blood and/or embolic(More)
