BACKGROUND To facilitate the optimal timing of pulmonary valve replacement, we analyzed preoperative thresholds of right ventricular (RV) volumes above which no decrease or normalization of RV size takes place after surgery. METHODS AND RESULTS Between 1993 and 2006, 71 adult patients with corrected tetralogy of Fallot underwent pulmonary valve(More)
OBJECTIVES Multidetector CT (MDCT) has shown potential for prosthetic heart valve (PHV) assessment. We assessed the image quality of different PHV types to determine which valves are suitable for MDCT evaluation. METHODS All ECG-gated CTs performed in our institutions since 2003 were reviewed for the presence of PHVs. After reconstruction in 3 specific(More)
Magnetic resonance imaging (MRI) is increasingly applied in the evaluation of uterine fibroids. However, little is known about the reproducibility of MRI in the assessment of uterine fibroids. This study evaluates the inter- and intraobserver variation in the assessment of the uterine fibroids and concomitant adenomyosis in women scheduled for uterine(More)
AIM Patients with Marfan syndrome have an increased risk of life-threatening aortic complications, mostly preceded by aortic dilatation. Treatment with losartan, an angiotensin-II receptor-1 blocker, may reduce aortic dilatation rate in Marfan patients. METHODS AND RESULTS In this multicentre, open-label, randomized controlled trial with blinded(More)
OBJECTIVE To study the accuracy of magnetic resonance imaging (MRI) in lymph node detection in patients with vulva carcinoma. METHODS Sixty patients with diagnosed vulva carcinoma underwent MRI examination for preoperative evaluation of lymph nodes. MRI images were read independently and retrospectively by two radiologists, both unaware of physical(More)
BACKGROUND Kawasaki disease (KD) is the most common cause of acquired coronary artery disease in childhood. In KD, the American Heart Association recommends echocardiography for routine coronary artery surveillance and nuclear perfusion scans and conventional coronary angiography in select patients. Cardiac MRI (CMRI) may be a noninvasive and radiation-free(More)
PURPOSE To retrospectively compare histopathological findings of surgically resected bowel segments with magnetic resonance imaging (MRI) findings on Crohn's disease activity. MATERIALS AND METHODS Patients who underwent a MR enterography or enteroclysis before surgery were included after informed consent. MRI features (T1-enhancement, T1 and T2(More)
The aim of this study was to analyze the effect of pressure and/or volume overload on right ventricular (RV) function and brain natriuretic peptide (BNP) levels in patients with surgically corrected congenital heart disease. Forty-two consecutive patients aged 17 to 57 years (median 30) with congenital heart disease (32 with tetralogy of Fallot and 10 with(More)
BACKGROUND Although histopathologic studies suggest persistent myocardial abnormalities after Kawasaki disease (KD), the long-term effects on cardiac function remain to be revealed. We investigated biventricular volumes, function, and the presence of myocardial fibrosis by cardiac magnetic resonance imaging during long-term follow-up of KD. METHODS AND(More)
OBJECTIVES In patients with pulmonary atresia with intact ventricular septum (PAIVS), biventricular repair is considered to be the optimal treatment option in the absence of significant right ventricular (RV) hypoplasia. However, long-term clinical outcome studies are limited. We evaluated exercise capacity and cardiac function during pharmacological stress(More)
