Abnormal pulmonary flow is associated with impaired right ventricular coupling in patients with COPD
AbstractCor Pulmonale or right ventricular (RV) dysfunction due to pulmonary disease is an expected complication of COPD resulting primarily from increased afterload mediated by chronic alveolar hypoxemia and resulting hypoxic pulmonary vasoconstriction. Early detection of elevated RV afterload has been previously demonstrated by visualization of abnormal flow patterns in the proximal pulmonary arteries. Prior analysis of helicity in the pulmonary arteries in pulmonary hypertension patients has demonstrated a strong association between helicity and increased RV afterload. However, these flow hemodynamics have yet to be ful...

Assessment of tricuspid annulus: anatomic and echocardiographic correlation
AbstractTricuspid regurgitation is associated with a poor outcome and its quantification remains a challenge. Tricuspid annulus dilatation is one of the parameters that influences clinical decision-making. The aim of this study was to compare the use of 2D transoesophageal echocardiography with surgical assessment for the measurement of the tricuspid annulus. Sixty-one cardiac patients (median age 64  years) were included in the study. Echocardiographic tricuspid annulus measurements were obtained from four chamber and transgastric short axis views and compared with the surgical measurements of this valve. The study w...

Predicting the need of aortic valve surgery in patients with chronic aortic regurgitation: a comparison between cardiovascular magnetic resonance imaging and transthoracic echocardiography
AbstractTo compare the ability of cardiac magnetic resonance tomography (CMR) and transthoracic echocardiography (TTE) to predict the need for valve surgery in patients with chronic aortic regurgitation on a mid-term basis. 66 individuals underwent assessment of aortic regurgitation (AR) both in CMR and TTE between August 2012 and April 2017. The follow-up rate was 76% with a median of 5.1  years. Cox proportional hazards method was used to assess the association of the time-to-aortic-valve-surgery, including valve replacement and reconstruction, and imaging parameters. A direct comparison of most predictive CMR and e...

Multi-plane echocardiographic assessment of right ventricular function in adults with repaired Tetralogy of Fallot
AbstractIn patients with repaired Tetralogy of Fallot (ToF), detailed assessment of right ventricular (RV) function is important for management and timing of possible pulmonary valve re-intervention.

Statistical shape analysis of the left atrial appendage predicts stroke in atrial fibrillation
AbstractThe shape of the left atrium (LA) and left atrial appendage (LAA) have been shown to predict stroke in patients with atrial fibrillation (AF). Prior studies rely on qualitative assessment of shape, which limits reproducibility and clinical utility. Statistical shape analysis (SSA) allows for quantitative assessment of shape. We use this method to assess the shape of the LA and LAA and predict stroke in patients with AF. From a database of AF patients who had previously undergone MRI of the LA, we identified 43 patients with AF who subsequently had an ischemic stroke. We also identified a cohort of 201 controls with...
