The American journal of cardiology, Volume 179, 15 3 2022, Pages 64-69 Effects of Left Bundle Branch Block and Pacemaker Implantation on Left Ventricular Systolic Function After Transcatheter Aortic Valve Implantation. Dolci G, Singh GK, Wang X, van der Kley F, de Weger A, Bootsma M, Ajmone Marsan N, Bax JJ, Delgado V
Permanent pacemaker implantation (PPI) and left bundle branch block (LBBB) frequency after transcatheter aortic valve implantation (TAVI) and their effect on left ventricular ejection fraction (LVEF) remain controversial. We evaluated the incidence of PPI and new-onset LBBB after TAVI and their impact on LVEF at 6-month follow-up. Moreover, the impact of right ventricular (RV) pacing burden on changes in LVEF after TAVI was analyzed. The electrocardiograms of 377 patients (age 80 ± 7 years, 52%... Abstract

The American journal of cardiology, Volume 177, 9 2 2022, Pages 90-99 Prognostic Implications of Change in Left Ventricular Ejection Fraction After Transcatheter Aortic Valve Implantation. Kuneman JH, Butcher SC, Singh GK, Wang X, Hirasawa K, van der Kley F, Leon MB, Knuuti J, Pibarot P, Ajmone Marsan N, Delgado V, Bax JJ
Reduced left ventricular (LV) systolic function is associated with worse prognosis in patients with severe aortic stenosis (AS) treated with transcatheter aortic valve implantation (TAVI). We aimed to examine the changes in left ventricular ejection fraction (LVEF) after TAVI among patients with varying baseline LVEF. Moreover, variables associated with lack of LVEF improvement were identified and the association with long-term outcomes was investigated. A total of 560 patients (age 80 ± 7 years... Abstract

The international journal of cardiovascular imaging, Volume 38, Issue 9, 21 3 2022, Pages 1973-1985 Interaction between sex and left ventricular reverse remodeling and its association with outcomes after transcatheter aortic valve implantation. Kuneman JH, Butcher SC, Stassen J, Singh GK, Pio SM, van der Kley F, Ajmone Marsan N, Knuuti J, Bax JJ, Delgado V
Women with severe aortic stenosis (AS) have better long-term prognosis after transcatheter aortic valve implantation (TAVI) compared to men. Whether this is caused by sex-related differences in left ventricular (LV) reverse remodeling after TAVI is unknown. Patients with severe AS who underwent transfemoral TAVI between 2007 and 2018 were selected. LV dimensions, volumes, and ejection fraction (LVEF) were assessed by transthoracic echocardiography before TAVI and at 6 and 12 months follow-up aft... Abstract
The Journal of invasive cardiology, Volume 33, Issue 12, 1 1 2021, Pages E1004 Delayed Iatrogenic Left Ventricular Apex Perforation Sealed With an Amplatzer Septal Occluder Device Under Transthoracic Echocardiography Guidance. Montero-Cabezas JM, Delgado V, van der Kley F
High rates of spontaneous rupture and death have been described when the pseudoaneurysm is left untreated. Percutaneous closure has emerged as an alternative to surgery in patients with unacceptable surgical risk. In this case, transthoracic echocardiography allowed optimal characterization of the defect and successful procedure guidance, avoiding risks derived from more invasive intraprocedural imaging techniques.
