OBJECTIVES The aim of this study was to determine the acute and long-term outcome of radiofrequency catheter ablation (RFCA) for intra-atrial re-entrant tachycardia (IART) in adults with congenital heart disease (CHD), and predictors of these outcomes. BACKGROUND Atrial myopathy can be progressive in CHD and contributes to the substrate for IART. Although(More)
AIMS To investigate outcome and complications of implantable cardioverter defibrillators (ICDs) in adults with congenital heart disease (CHD) and to identify predictors of (in-) appropriate shocks. METHODS AND RESULTS Sixty-four CHD patients >/= 18 years at first ICD implantation [63% tetralogy of Fallot (TOF) and age at implantation 37 +/- 13 years] were(More)
OBJECTIVE We aimed to compare velocity-encoded cine cardiac magnetic resonance (CMR) with an established echocardiographic method for noninvasive measurement of aortic valve area (AVA) using the continuity equation. METHODS AND RESULTS Twenty consecutive young adults with stenotic bicuspid aortic valves were examined with CMR and transthoracic(More)
INTRODUCTION The prevalence of intra-atrial reentrant tachycardia (IART) increases with age in Fontan patients. This study aimed to characterize the atrial electroanatomic substrate for IART late after Fontan surgery. METHODS AND RESULTS Detailed electroanatomic mapping of the right atrium (RA) was performed in 11 consecutive patients (33 ± 9 years) with(More)
Aortic stenosis at young adult age is usually the result of a stenotic bicuspid aortic valve, which is the most common cardiac congenital anomaly. In clinical practice, exercise and pregnancy are important topics. Furthermore, the timing of intervention is under debate, as little information is available on the natural history and outcome after aortic valve(More)
BACKGROUND Patients with severe aortic stenosis (AS) require valve replacement before development of irreversible left ventricular (LV) dysfunction. It has been postulated that Doppler tissue imaging (DTI) parameters are more sensitive to detect subtle LV dysfunction compared with conventional echocardiographic parameters. OBJECTIVE We sought to assess(More)
AIMS Longevity of implantable cardioverter defibrillators (ICDs) is crucial for patients and healthcare systems as replacements impact on infection rates and cost-effectiveness. Aim was to determine longevity using very large databases of two teaching hospitals with a high number of replacements and a rather homogeneous distribution among manufacturers. (More)
BACKGROUND Poor catheter-to-myocardial contact can lead to ineffective ablation lesions and suboptimal outcome. Contact force (CF) sensing catheters in ventricular tachyarrhythmia (VT) ablations have not been studied for their long-term efficacy. PURPOSE The aim of this study was to compare CF ablation to manual ablation (MAN) and remote magnetic(More)
A 37-year-old man was admitted after experiencing an out-of-hospital cardiac arrest due to ventricular fibrillation. He was successfully resuscitated and had good neurologic recovery. During admission, he was diagnosed with Brugada syndrome and received a subcutaneous implantable cardioverter-defibrillator (S-ICD; Boston Scientific, Marlborough, MA) using a(More)
There is an essential importance of non-invasive imaging methods for evaluation of cardiac patients. Theoretically, the heart can be examined exactly, if due to its nature assessed in three dimensions (3D) concerning the heart cycle. In recent studies it has been confirmed that the second-generation real-time three-dimensional echocardiography offers(More)
