International journal of cardiology. Heart & vasculature, Volume 52, 2 1 2024, Pages 101418 Coronary calcifications as assessed on routine non-gated chest CT; a gatekeeper to tailor downstream additional imaging in patients with stable chest pain. Groen RA, van Dijkman PRM, Jukema JW, Bax JJ, Lamb HJ, de Graaf MA
Background and aims: Currently applied methods for risk-assessment in coronary artery disease (CAD) often overestimate patients' risk for obstructive CAD. To enhance risk estimation, assessment of coronary artery calcium (CAC) can be applied. In 10 % of patients presenting with stable chest pain a previous non-gated computed tomography (CT) has been performed, suitable for CAC-assessment. This study is the first to investigate the clinical utility of CAC-assessment on non-gated CT for risk-... Abstract

JACC. Cardiovascular imaging, 18 3 2024, Pages S1936-878X(24)00119-0 Mitral Annular Disjunction in the Context of Mitral Valve Prolapse: Identifying the At-Risk Patient. Van der Bijl P, Stassen J, Haugaa KH, Essayagh B, Basso C, Thiene G, Faletra FF, Edvardsen T, Enriquez-Sarano M, Nihoyannopoulos P, Ajmone Marsan N, Chandrashekhar YS, Bax JJ
Mitral annular disjunction (MAD), a separation between the left atrium/mitral valve annulus and the left ventricular myocardium, is frequently seen in patients with arrhythmic mitral valve prolapse. Although an association exists between MAD and ventricular arrhythmias, little is known regarding the identification of individuals at high risk. Multimodality imaging including echocardiography, computed tomography, cardiac magnetic resonance, and positron emission tomography can play an important r... Abstract

Atrial secondary tricuspid regurgitation (A-STR) is a distinct phenotype of secondary tricuspid regurgitation with predominant dilation of the right atrium and normal right and left ventricular function. Atrial secondary tricuspid regurgitation occurs most commonly in elderly women with atrial fibrillation and in heart failure with preserved ejection fraction in sinus rhythm. In A-STR, the main mechanism of leaflet malcoaptation is related to the presence of a significant dilation of the tricusp... Abstract
Heart (British Cardiac Society), Volume 110, Issue 6, 23 4 2024, Pages 448-456 Association of right atrial strain and long-term outcome in severe secondary tricuspid regurgitation. Galloo X, Fortuni F, Meucci MC, Butcher SC, Dietz MF, Prihadi EA, Cosyns B, Delgado V, Bax JJ, Ajmone Marsan N
Objective: Severe secondary tricuspid regurgitation (STR) causes significant right atrial (RA) volume overload, resulting in structural and functional RA-remodelling. This study evaluated whether patients with severe STR and reduced RA function, as assessed by RA-reservoir-strain (RASr), show lower long-term prognosis. Methods: Consecutive patients, from a single centre, with first diagnosis of severe STR and RASr measure available, were included. Extensive echocardiographic analysis comprised m... Abstract
