European heart journal. Cardiovascular Imaging, Volume 23, Issue 5, 1 1 2022, Pages 699-707 Prognostic implications of left ventricular myocardial work index in patients with ST-segment elevation myocardial infarction and reduced left ventricular ejection fraction. Butcher SC, Lustosa RP, Abou R, Marsan NA, Bax JJ, Delgado V
Aims: This study aimed to determine whether lower values of left ventricular (LV) global work index (GWI) at baseline were associated with a reduction in LV functional recovery and poorer long-term prognosis in patients with reduced LV ejection fraction (LVEF ≤40%) following ST-segment elevation myocardial infarction (STEMI). Methods and results: A total of 197 individuals (62 ± 12 years, 75% male) with STEMI treated with primary percutaneous coronary intervention and reduced LVEF were evaluated... Abstract

The American journal of cardiology, Volume 173, 1 1 2022, Pages 120-127 Prognostic Implications of Right Ventricular Systolic Dysfunction in Cardiac Amyloidosis. Tjahjadi C, Fortuni F, Stassen J, Debonnaire P, Lustosa RP, Marsan NA, Delgado V, Bax JJ
Left ventricular (LV) systolic dysfunction in cardiac amyloidosis (CA) is associated with poor prognosis. This study aimed to investigate the prognostic implications of right ventricular (RV) systolic dysfunction in CA. A total of 93 patients diagnosed with CA who underwent standard and speckle-tracking echocardiography were included. During a median follow-up of 17 (5 to 38) months, 42 patients (45%) died. Nonsurvivors were more likely to present with immunoglobulin light-chain amyloidosis and... Abstract

Min JK, Chang HJ, Andreini D, Pontone G, Guglielmo M, Bax JJ, Knaapen P, Raman SV, Chazal RA, Freeman AM, Crabtree T, Earls JP
Background: Atherosclerotic plaque characterization by coronary computed tomography angiography (CCTA) enables quantification of coronary artery disease (CAD) burden and type, which has been demonstrated as the strongest discriminant of future risk of major adverse cardiac events (MACE). To date, there are no clinically useful thresholds to assist with understanding a patient's disease burden and guide diagnosis and management, as there exists with coronary artery calcium (CAC) scoring. The... Abstract

The distribution of epicardial adipose tissue (EAT) across the spectrum of heart failure (HF) has yet to be fully elucidated. The present study investigated the distribution of EAT in an HF spectrum and its association with clinical and echocardiographic parameters. A total of 326 patients who underwent contrast-enhanced computed tomography before transcatheter atrial fibrillation ablation with and without HF symptoms, and a wide range of left ventricular (LV) ejection fractions (LVEF) were incl...

Frontiers in cardiovascular medicine, Volume 9, 17 3 2022, Pages 845359 The Prognostic Value of Right Atrial and Right Ventricular Functional Parameters in Systemic Sclerosis. Vos JL, Butcher SC, Fortuni F, Galloo X, Rodwell L, Vonk MC, Bax JJ, van Leuven SI, de Vries-Bouwstra JK, Snoeren M, El Messaoudi S, Marsan NA, Nijveldt R
Introduction: Right ventricular (RV) function is of particular importance in systemic sclerosis (SSc), since common SSc complications, such as interstitial lung disease and pulmonary hypertension may affect RV afterload. Cardiovascular magnetic resonance (CMR) is the gold standard for measuring RV function. CMR-derived RV and right atrial (RA) strain is a promising tool to detect subtle changes in RV function, and might have incremental value, however, prognostic data is lacking. Therefore, the...

Stassen J, Pio SM, Ewe SH, Singh GK, Hirasawa K, Butcher SC, Cohen DJ, Généreux P, Leon MB, Marsan NA, Delgado V, Bax JJ
Moderate aortic stenosis (AS) is associated with an increased risk for adverse events. Although reduced left ventricular (LV) global longitudinal strain (GLS) is associated with worse outcomes in patients with severe AS, its prognostic value in patients with moderate AS is unknown. The aim of this study was to investigate the prognostic implications of LV GLS in patients with moderate AS. Methods: LV GLS was evaluated using speckle-tracking echocardiography in patients with moderate AS (aortic v... Abstract

Cardiovascular Imaging, Volume 23, Issue 4, 1 1 2022, Pages 578-585 Prognostic implications of cardiac damage classification based on computed tomography in severe aortic stenosis. Hirasawa K, vanRosendael PJ, Fortuni F, Singh GK, Kuneman JH, Vollema EM, Ajmone Marsan N, Knuuti J, Bax JJ, Delgado V
Aims: An echocardiographic staging system of severe aortic stenosis (AS) based on additional extra-valvular cardiac damage has been associated with prognosis after transcatheter aortic valve implantation (TAVI). Multidetector row computed tomography (MDCT) is key in the evaluation of AS patients undergoing TAVI and can potentially detect extra-valvular cardiac damage.

Importance: Distinct plaque locations and vessel geometric features predispose to altered coronary flow hemodynamics. The association between these lesion-level characteristics assessed by coronary computed tomographic angiography (CCTA) and risk of future acute coronary syndrome (ACS) is unknown. Objective: To examine whether CCTA-derived adverse geometric characteristics (AGCs) of coronary lesions describing location and vessel geometry add to plaque morphology and burden for identifying culpr...

The American journal of cardiology, Volume 170, 21 3 2022, Pages 1-9 Prognostic Relevance of Right Ventricular Remodeling after ST-Segment Elevation Myocardial Infarction in Patients Treated With Primary Percutaneous Coronary Intervention. Chimed S, van der Bijl P, Lustosa RP, Hirasawa K, Yedidya I, Fortuni F, van der Velde E, Montero-Cabezas JM, Marsan NA, Gersh BJ, Delgado V, Bax JJ
ST-segment elevation myocardial infarction (STEMI) often leads to changes in right ventricular (RV) function and size over time. The prognostic implications of RV remodeling after STEMI, however, are unknown. RV remodeling in patients who underwent STEMI with primary percutaneous coronary intervention (PCI) was defined by RV end-systolic area (RV ESA) change at 6 months after STEMI compared with baseline. The optimal threshold of RV ESA change (≥40%) to define RV remodeling was derived from spli... Abstract

Background: Cardiac resynchronization therapy (CRT) candidates often present with significant mitral and tricuspid regurgitation, pulmonary hypertension and right ventricular dysfunction when referred for device implantation. This study investigated the prognostic value of a novel cardiac staging system, based on the extent of cardiac remodeling prior to implantation.

Objective: The purpose of this study was to evaluate the impact of baseline LV volumes on LV reverse remodeling after CRT and whether this is associated with improved survival. Methods: Patients were stratified into quintiles according to baseline LV end-diastolic volume indexed for body surface area (LVEDVi). LV reverse remodeling was defined as ≥15% reduction in LV end-sy... Abstract

Background: Diabetes mellitus is a major risk factor for coronary artery disease (CAD) and may provoke structural and functional changes in coronary vasculature. The coronary volume to left ventricular mass (V/M) ratio is a new anatomical parameter capable of revealing a potential physiological imbalance between coronary vasculature and myocardial mass. The aim of this study was to examine the V/M derived from coronary computed tomography angiography (CCTA) in patients with diabetes. Methods: Pa... Abstract
