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
Progressive right ventricular dysfunction in patients with pulmonary arterial hypertension responding to therapy.
Mariëlle C. van de Veerdonk,Taco Kind,J. Tim Marcus,Gert-Jan Mauritz,Martijn W. Heymans,Harm-Jan Bogaard,Harm-Jan Bogaard,Anco Boonstra,Koen M. Marques,Nico Westerhof,Anton Vonk-Noordegraaf +10 more
TL;DR: After PAH-targeted therapy, RV function can deteriorate despite a reduced PVR, and loss of RV function is associated with a poor outcome, irrespective of any changes in PVR.
Journal ArticleDOI
Percutaneous Intervention for Concurrent Chronic Total Occlusions in Patients With STEMI: The EXPLORE Trial
José P.S. Henriques,Loes P. Hoebers,Truls Råmunddal,Peep Laanmets,Erlend Eriksen,Matthijs Bax,Dan Ioanes,Maarten J. Suttorp,Bradley H. Strauss,Emanuele Barbato,Robin Nijveldt,Albert C. van Rossum,Koen M. Marques,Joëlle Elias,Ivo M. van Dongen,Bimmer E. Claessen,Jan G.P. Tijssen,René J. van der Schaaf +17 more
TL;DR: The finding that early CTO PCI in the left anterior descending coronary artery subgroup was beneficial warrants further investigation, and the overall benefit for CTOPCI in terms of LVEF or LVEDV was not found in patients with STEMI and concurrent CTO.
Journal ArticleDOI
Quantification of right ventricular afterload in patients with and without pulmonary hypertension.
Jan-Willem Lankhaar,Nicolaas Westerhof,Theo J.C. Faes,Koen M. Marques,J. Tim Marcus,P E Postmus,Anton Vonk-Noordegraaf +6 more
TL;DR: The results show that differences in RV afterload among groups with different forms of PH can be quantified with a windkessel model and suggest that the RC time and the elastic properties of the large pulmonary arteries remain unchanged in PH.
Journal ArticleDOI
Impaired left ventricular filling due to right-to-left ventricular interaction in patients with pulmonary arterial hypertension.
C. Tji-Joong Gan,Jan-Willem Lankhaar,J. Tim Marcus,Nico Westerhof,Koen M. Marques,Jean G.F. Bronzwaer,Anco Boonstra,Pieter E. Postmus,Anton Vonk-Noordegraaf +8 more
TL;DR: In PAH patients, ventricular interaction mediated by the interventricular septum impairs left ventricular filling, contributing to decreased stroke volume.
