Journal ArticleDOI
Prognostic value of right ventricular mass, volume, and function in idiopathic pulmonary arterial hypertension.
Serge A. van Wolferen,J.T. Marcus,Anco Boonstra,Koen M. Marques,Jean G.F. Bronzwaer,Marieke D. Spreeuwenberg,Pieter E. Postmus,Anton Vonk-Noordegraaf +7 more
TL;DR: The RV contains prognostic information in IPAH and a large RV volume, low SV, and a reduced LV volume are strong independent predictors of mortality and treatment failure.
Journal ArticleDOI
Timing of cardiac contraction in humans mapped by high-temporal-resolution MRI tagging: early onset and late peak of shortening in lateral wall
Jaco J.M. Zwanenburg,M.J.W. Gotte,Joost P.A. Kuijer,Robert M. Heethaar,A.C. van Rossum,J.T. Marcus +5 more
TL;DR: Maps of the timing of contraction in normal subjects may serve as a reference in detecting mechanical asynchrony due to intraventricular conduction defects or ischemia in healthy persons.
Journal ArticleDOI
Sildenafil treatment in COPD does not affect stroke volume or exercise capacity.
Heleen Rietema,S. Holverda,Herman J Bogaard,J.T. Marcus,Henk Smit,Nico Westerhof,P E Postmus,Anco Boonstra,Anton Vonk-Noordegraaf +8 more
TL;DR: A reduced stroke volume was found at rest and during exercise and neither stroke volume nor exercise capacity were improved by 3 months of sildenafil therapy.
Journal ArticleDOI
Accurate assessment of load-independent right ventricular systolic function in patients with pulmonary hypertension
Pia Trip,Taco Kind,Mariëlle C. van de Veerdonk,J.T. Marcus,Frances S. de Man,Nico Westerhof,Anton Vonk-Noordegraaf +6 more
TL;DR: Findings show that V(0) is dependent on RV dilation, and the assumption that E(es) is negligible in PAH is incorrect, and for an accurate assessment of load-independent RV systolic function, RV volumes and pressure curves are required.
Journal ArticleDOI
RC time constant of single lung equals that of both lungs together: a study in chronic thromboembolic pulmonary hypertension
Nabil Saouti,Nico Westerhof,Frank Helderman,J.T. Marcus,Nikolaos Stergiopulos,Berend E. Westerhof,Anco Boonstra,P E Postmus,Anton Vonk-Noordegraaf +8 more
TL;DR: R and C in individual lungs in chronic thromboembolic pulmonary hypertension patients where resistances differ between both lungs are determined, and the contribution of the proximal pulmonary arteries (PA) to total lung compliance was assessed.
