Aims: Multidetector row computed tomography (MDCT) may help to understand the underlying mechanisms of functional tricuspid regurgitation (TR), a highly prevalent valve disease with novel transcatheter therapies under development. The purpose of the present study was to assess the geometrical changes of the tricuspid valve in patients with functional TR using MDCT and to correlate these changes with the TR grade assessed with echocardiography. Methods and results: In 114 patients undergoing tran... Abstract

European heart journal, Volume 36, Issue 31, 1 1 2015, Pages 2087-2096 Low gradient severe aortic stenosis with preserved ejection fraction: reclassification of severity by fusion of Doppler and computed tomographic data. Kamperidis V, van Rosendael PJ, Katsanos S, van der Kley F, Regeer M, Al Amri I, Sianos G, Marsan NA, Delgado V, Bax JJ
Aims: Low gradient severe aortic stenosis (AS) with preserved left ventricular ejection fraction (LVEF) may be attributed to aortic valve area index (AVAi) underestimation due to the assumption of a circular shape of the left ventricular outflow tract (LVOT) with 2-dimensional echocardiography. The current study evaluated whether fusing Doppler and multidetector computed tomography (MDCT) data to calculate AVAi results in significant reclassification of inconsistently graded severe AS. Methods a... Abstract

JACC. Cardiovascular interventions, Volume 8, Issue 5, 1 1 2015, Pages 670-677 Surgical sutureless and transcatheter aortic valves: hemodynamic performance and clinical outcomes in propensity score-matched high-risk populations with severe aortic stenosis.

The American journal of cardiology, Volume 115, Issue 12, 24 4 2015, Pages 1726-1732 Timing of staged percutaneous coronary intervention before transcatheter aortic valve implantation. van Rosendael PJ, van der Kley F, Kamperidis V, Katsanos S, Al Amri I, Regeer M, Schalij MJ, Ajmone Marsan N, Bax JJ, Delgado V
Significant coronary artery disease is highly prevalent in patients who underwent transcatheter aortic valve implantation (TAVI). Timing of staged percutaneous coronary intervention (PCI) in TAVI candidates remains debated. The present study assessed the impact of timing of the staged PCI on TAVI outcomes. Ninety-six patients (age 81 ± 5 years, 57% men) who had undergone staged PCI within 1 year before TAVI were included. The population was dichotomized according to the median time elapsed betwe...

Mitral regurgitation is one of the most prevalent valvular heart diseases and its prevalence is related to population aging. Elderly patients with age-associated co-morbidities have an increased risk for conventional mitral valve surgery. Transcatheter mitral valve repair has emerged as a feasible and safe alternative in patients with contraindications for surgery or high operative risk. Several transcatheter mitral repair technologies have been developed during the last decade. While the develo... Abstract

Background: Atheroembolic renal disease, due to dislodgement of cholesterol crystals during maneuvering of a large catheter across the aorta and deployment of the transcatheter prosthesis within a calcified aortic valve, may be one of the pathophysiological mechanisms of acute kidney injury (AKI) complicating transcatheter aortic valve implantation (TAVI). Objective: To investigate the association between the atherosclerotic burden and plaque characteristics of the aortic valve and thoracic aort... Abstract

Ewe SH, Muratori M, van der Kley F, Pepi M, Delgado V, Tamborini G, Fusini L, de Weger A, Gripari P, Bartorelli A, Bax JJ, Marsan NA
The prognosis of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and the changes in AR grade over time remain unclear. This study evaluated the midterm survival associated with AR after TAVI and examined the evolution of AR over time and its effect on cardiac performance. Successful TAVI was performed in 314 patients (age 81 ± 7 years, 36% men). Serial transthoracic echocardiography and clinical assessment were available in 175 patients who survived >12 months....

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

Kamperidis V, van Rosendael PJ, Ng AC, Katsanos S, van der Kley F, Debonnaire P, Joyce E, Sianos G, Marsan NA, Bax JJ, Delgado V
The prognostic implications of flow, assessed by stroke volume index (SVi), and left ventricular (LV) global longitudinal strain on survival of patients with low-gradient severe aortic stenosis (AS) and preserved LV ejection fraction are debated. The aim of this study was to evaluate the impact of flow and LV global longitudinal strain on survival in these patients treated with aortic valve replacement (AVR).

The American journal of cardiology, Volume 114, Issue 10, 27 4 2014, Pages 1556-1561 Insights into new-onset rhythm conduction disorders detected by multi-detector row computed tomography after transcatheter aortic valve implantation. Katsanos S, van Rosendael P, Kamperidis V, van der Kley F, Joyce E, Debonnaire P, Karalis I, Bax JJ, Marsan NA, Delgado V
New-onset rhythm conduction disorders are frequent after transcatheter aortic valve implantation (TAVI). Multidetector row computed tomography may shed light on the pathophysiology of rhythm conduction disorders in patients who undergo TAVI with the Edwards SAPIEN valve. A total of 94 patients (mean age 81 ± 7 years, 48% men) treated with TAVI with the Edwards SAPIEN valve who underwent pre- and post-TAVI multidetector row computed tomography were included. Patients with preexisting right bundle... 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

Kamperidis V, Joyce E, Debonnaire P, Katsanos S, van Rosendael PJ, van der Kley F, Sianos G, Bax JJ, Ajmone Marsan N, Delgado V
Background: Speckle-tracking-derived global longitudinal strain (GLS) is a more sensitive method of detecting left ventricular (LV) functional recovery after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis. However, it remains unknown whether LV function improves in patients with low-flow, low-gradient severe aortic stenosis (LFLGSAS) after TAVI. The aim of the present was to evaluate LV functional recovery and remodeling after TAVI in patients with LFLGSAS... Abstract

Objectives: Osteogenesis imperfecta is associated with increased prevalence of significant mitral valve regurgitation. Surgical mitral valve repair and replacement are feasible but are associated with increased risk of bleeding and dehiscence of implanted valves may occur more frequently. The present case report describes the outcomes of transcatheter mitral valve repair in a patient with osteogenesis imperfecta. Patients/methods: A 60 year-old patient with osteogenesis imperfecta and associated... Abstract
