This report of an ESC Study Group reviews current knowledge on myocardial hibernation and relevant imaging techniques, and provides an algorithm for investigation and management when a patient presents with ischaemic left ventricular dysfunction. It covers the definitions of myocardial viability, stunning and hibernation, it reviews the morphological(More)
Assessment of right heart function remains difficult despite rapid technological echocardiographic developments. This review addresses the anatomical and physiological basis for assessment of right ventricular function. It also addresses advantages and limitations of individual echocardiographic techniques currently used in clinical and academic practice.(More)
AIMS The purpose of this study was to compare the noninvasive assessment of severity of pulmonary regurgitation with Doppler echocardiography versus cardiovascular magnetic resonance imaging (CMR) in adult patients with repaired tetralogy of Fallot (rTOF). METHODS We studied 52 (22 females) consecutive patients (aged 32 +/- 2 years, 23 +/- 5 years after(More)
BACKGROUND In a small but significant group of elderly patients who present with breathlessness, dynamic left-ventricular outflow tract obstruction (DLVOTO) may be responsible for symptom generation. The aim of our study was to investigate the effect of beta-blockade on ventricular physiology and symptoms in patients with DLVOTO. METHODS We performed a(More)
AIMS Long-standing aortic stenosis (AS) causes various degrees of left ventricular (LV) dysfunction, which may improve after valve replacement. The aim of this study was to assess the nature of LV subendocardial abnormalities in AS and their response to valve replacement (AVR). METHODS AND RESULTS We studied 41 consecutive symptomatic patients (age 64 +/-(More)
BACKGROUND Aortic valve replacement (AVR) is the established treatment for severe aortic stenosis. In response to the long-term results of aortic homografts, stentless porcine valves were introduced as an alternative low-resistance valve. We conducted a randomized trial comparing a stentless with a stented porcine valve in adults with severe aortic(More)
BACKGROUND Pulsed Wave Tissue Doppler (PWTD) recording of myocardial velocities has been widely used for assessing ventricular function but the output trace has finite thickness that leads to potential ambiguity in determining velocity and timing. OBJECTIVE To determine optimal method of measurement of PWTD traces by comparing them with those obtained(More)
UNLABELLED Current echocardiographic assessment of fetal ventricular function uses relatively crude measures and this has led to inconsistencies in assessment of diastolic function. Long axis parameters may be more insightful. OBJECTIVE To describe fetal long axis cardiac function and construct reference ranges. DESIGN 159 normal fetuses were studied(More)
We report a case of a right coronary artery (RCA) originating from the mid-left anterior descending artery (LAD) coursing around and in front of the pulmonary artery. The anomaly was discovered incidentally during cardiac catheterization. It is only the second case of such an anomaly ever described.
AIMS Cardiac resynchronization therapy (CRT) reduces inter- and intraventricular dyssynchrony and shortens total isovolumic time (t-IVT). We compared the extent to which the values of ventricular dyssynchrony and t-IVT predict clinical benefits of CRT. METHODS AND RESULTS Ventricular dyssynchrony was assessed in 39 patients with heart failure before and 6(More)
