Relationship between right ventricular volumes measured by cardiac magnetic resonance imaging and prognosis in patients with chronic heart failure.
Christos V. Bourantas,Huan P. Loh,Thanjavur Bragadeesh,Alan S. Rigby,Elena I. Lukaschuk,Scot Garg,Ann C. Tweddel,Farqad Alamgir,Nikolay P. Nikitin,Andrew L. Clark,John G.F. Cleland +10 more
TL;DR: The aim of this study was to investigate the prognostic impact of right ventricular (RV) size in patients with chronic heart failure.

Simon Thackray,Justin Ghosh,Graham A Wright,Klaus K. Witte,Nikolay P. Nikitin,Gerald C. Kaye,Andrew L. Clark,Ann C. Tweddel,John G.F. Cleland +8 more
TL;DR: In this paper, a randomized, double-blind, parallel group study comparing chronic higher-rate with lower-rate (60 pulses per minute) pacing in pacemaker-dependent patients with symptomatic left ventricular (LV) systolic dysfunction, receiving β-blockers was conducted.

Prevalence of scarred and dysfunctional myocardium in patients with heart failure of ischaemic origin: A cardiovascular magnetic resonance study
Christos V. Bourantas,Nikolay P. Nikitin,Huan P. Loh,Elena I. Lukaschuk,Nassar Sherwi,Ramesh de Silva,Ann C. Tweddel,Mohamed F. Alamgir,Kenneth Wong,Sanjay Gupta,Andrew L. Clark,John G.F. Cleland +11 more
TL;DR: In this cohort of patients with left ventricular systolic dysfunction and ischaemic heart disease, about half of all segments had contractile dysfunction but only one third of these had > 50% of the wall thickness affected by scar, suggesting that most dysfunctional segments could improve in response to an appropriate intervention.
Comparison of quantitative coronary angiography with intracoronary ultrasound. Can quantitative coronary angiography accurately estimate the severity of a luminal stenosis
Christos V. Bourantas,Christos V. Bourantas,Ann C. Tweddel,Michail I. Papafaklis,Petros Karvelis,Dimitrios I. Fotiadis,Christos S. Katsouras,Lampros K. Michalis +7 more
TL;DR: Results provide evidence that orthogonal biplane angiography is more reliable and should be preferred to assess luminal dimensions and by increasing the angle between the biplane projections, the correlation between intracoronary ultrasound and mean estimations improves.
