The American journal of cardiology, Volume 115, Issue 2, 29 5 2014, Pages 234-242 Value of the "TAVI2-SCORe" versus surgical risk scores for prediction of one year mortality in 511 patients who underwent transcatheter aortic valve implantation. Debonnaire P, Fusini L, Wolterbeek R, Kamperidis V, van Rosendael P, van der Kley F, Katsanos S, Joyce E, Tamborini G, Muratori M, Gripari P, Bax JJ, Marsan NA, Pepi M, Delgado V
A bedside-available transcatheter aortic valve implantation (TAVI)-dedicated prognostic risk score is an unmet clinical need. We aimed to develop such a risk score predicting 1-year mortality post-TAVI and to compare it with the performance of the logistic EuroSCORE (LES) I and LES-II and the Society of Thoracic Surgeons' (STS) score. Baseline variables of 511 consecutive patients who underwent TAVI that were independently associated with 1-year mortality post-TAVI were included in the &quo... Abstract

The international journal of cardiovascular imaging, Volume 31, Issue 1, 17 3 2014, Pages 37-43 Pericardial effusion following transcatheter aortic valve implantation: echocardiography and multi-detector row computed tomography evaluation. Katsanos S, van Rosendael P, Kamperidis V, van der Kley F, Regeer M, Al-Amri I, Karalis I, Palmen M, de Weger A, Marsan NA, Bax JJ, Delgado V
Although pericardial effusion (PE) early after transcatheter aortic valve implantation (TAVI) has been reported in few registries, late PE at follow-up remains unexplored. Particularly, after transapical TAVI, diagnosis of PE with transthoracic echocardiography (TTE) may be challenging. The present evaluation assessed the incidence of PE early after TAVI and at 1 month follow-up using TTE and multi-detector computed tomography (MDCT). The agreement between TTE and MDCT to diagnose the presence a... Abstract

Clinical and experimental rheumatology, Volume 32, Issue 6 Suppl 86, 17 3 2014, Pages S-60-7 Detection of pulmonary vasculopathy by novel analysis of oxygen uptake in patients with systemic sclerosis: association with pulmonary arterial pressures. Ninaber MK, Hamersma WB, Schouffoer AA, Kovacs G, Olschewski H, Holman ER, Ajmone Marsan N, Stolk J
Objectives: During cardiopulmonary exercise testing (CPET) compromised pulmonary vasculature in patients with systemic sclerosis (SSc) may lead to increases in pulmonary arterial pressures (PAP) and decreased oxygen uptake. We hypothesised that this may lead into a disproportional heart rate (HR) increase with a corresponding V'O₂/HR breakpoint and relates to systolic PAP at rest. Methods: In a prospective design we evaluated V'O₂/HR slopes for breakpoints. To understand its physiologi... Abstract
