As a consequence of improved technology, there is growing clinical interest in the use of multi-detector row computed tomography (MDCT) for non-invasive coronary angiography. Indeed, the accuracy of MDCT to detect or exclude coronary artery stenoses has been high in many published studies. This report of a Writing Group deployed by the Working Group Nuclear Cardiology and Cardiac CT (WG 5) of the European Society of Cardiology and the European Council of Nuclear Cardiology summarizes the present...

Journal of the American College of Cardiology, Volume 50, Issue 21, 7 1 2007, Pages 2071-2077 Acute effects of initiation and withdrawal of cardiac resynchronization therapy on papillary muscle dyssynchrony and mitral regurgitation. Ypenburg C, Lancellotti P, Tops LF, Bleeker GB, Holman ER, Piérard LA, Schalij MJ, Bax JJ
Objectives: The purpose of this study was to evaluate the relationship between dyssynchrony involving the mitral valve apparatus and the acute improvement in mitral regurgitation (MR) after cardiac resynchronization therapy (CRT). The effect of interruption of CRT at 6 months' follow-up on dyssynchrony and MR was also evaluated. Background: Mitral regurgitation may improve acutely after CRT, but the precise mechanism is not fully understood. Methods: Out of 63 consecutive patients with base... Abstract

Heart (British Cardiac Society), Volume 93, Issue 11, 1 1 2007, Pages 1461-1470 Multi-modality imaging to assess left atrial size, anatomy and function. Tops LF, van der Wall EE, Schalij MJ, Bax JJ
The left atrium (LA) anterior-posterior diameter was one of the first standardised echocardiographic parameters. However, the clinical importance of LA size assessment has been neglected for some time. Recent population-based studies have demonstrated the prognostic value of LA size for long-term outcome. Furthermore, with new dedicated techniques such as tissue Doppler imaging, it has become feasible to assess (regional) LA function. In addition, the introduction of catheter ablation procedures...

Journal of the American College of Cardiology, Volume 50, Issue 15, 24 4 2007, Pages 1476-1483 Combined longitudinal and radial dyssynchrony predicts ventricular response after resynchronization therapy. Gorcsan J, Tanabe M, Bleeker GB, Suffoletto MS, Thomas NC, Saba S, Tops LF, Schalij MJ, Bax JJ
Objectives: The purpose of this study was to test the hypothesis that a combined echocardiographic assessment of longitudinal dyssynchrony by tissue Doppler imaging (TDI) and radial dyssynchrony by speckle-tracking strain may predict left ventricular (LV) functional response to cardiac resynchronization therapy (CRT). Background: Mechanical LV dyssynchrony is associated with response to CRT; however, complex patterns may exist. Methods: We studied 190 heart failure patients (ejection fraction [E... Abstract

Journal of the American College of Cardiology, Volume 50, Issue 12, 4 1 2007, Pages 1180-1188 Speckle-tracking radial strain reveals left ventricular dyssynchrony in patients with permanent right ventricular pacing. Tops LF, Suffoletto MS, Bleeker GB, Boersma E, van der Wall EE, Gorcsan J, Schalij MJ, Bax JJ
Objectives: Speckle-tracking strain analysis was used to assess the effects of permanent right ventricular (RV) pacing on the heterogeneity in timing of regional wall strain and left ventricular (LV) dyssynchrony. Background: Recent studies have shown detrimental effects of RV pacing, possibly related to the induction of LV dyssynchrony. Methods: Fifty-eight patients treated with His bundle ablation and pacemaker implantation were studied. To assess the effect of RV pacing on time-to-peak radial... Abstract

Circulation, Volume 115, Issue 11, 12 2 2007, Pages 1426-1432 Noninvasive evaluation of coronary sinus anatomy and its relation to the mitral valve annulus: implications for percutaneous mitral annuloplasty. Tops LF, Van de Veire NR, Schuijf JD, de Roos A, van der Wall EE, Schalij MJ, Bax JJ
Background: Percutaneous mitral annuloplasty has been proposed as an alternative to surgical annuloplasty. In this respect, evaluation of the coronary sinus (CS) and its relation with the mitral valve annulus (MVA) and the coronary arteries is relevant. The feasibility of evaluating these issues noninvasively with multislice computed tomography was determined. Methods and results: In 105 patients (72 men, age 59+/-11 years), 64-slice multislice computed tomography was performed for noninvasive e... Abstract

Objectives: This study was designed to assess the effects of long-term right ventricular (RV) pacing on left ventricular (LV) dyssynchrony, LV function, and heart failure symptoms. Background: Atrioventricular (AV) node ablation and subsequent long-term RV pacing is a well-established treatment option in patients with atrial fibrillation (AF). Methods: In 55 patients with drug-refractory AF, AV node ablation and implantation of a pacemaker was performed. At baseline and after a mean of 3.8 +/- 1... Abstract

Introduction: Ablation of atrial tachycardia (AT) occurring late after cardiac surgery for congenital heart disease can be challenging due to the complexity of the arrhythmogenic substrate. Methods and results: We performed an ablation procedure in a Fontan patient with an AT using a new approach combining 3D electroanatomical mapping with multislice computed tomography (MSCT). This technique visualizes the position of the catheter in relation to the endocardium, thereby improving delineation of... Abstract

Left atrial (LA) remodeling is associated with atrial fibrillation (AF). Radiofrequency catheter ablation offers a good treatment option for AF, with reasonable long-term results. The purpose of the present study was to assess whether LA reverse remodeling occurs after successful catheter ablation. Fifty-seven consecutive patients (45 men; age 53 +/- 8 years) with symptomatic drug-refractory AF were treated with radiofrequency catheter ablation. The patients were divided into 2 groups on the bas... Abstract
