Heart and vessels, Volume 31, Issue 5, 1 1 2015, Pages 795-806 Histopathology of aortic complications in bicuspid aortic valve versus Marfan syndrome: relevance for therapy? Grewal N, Franken R, Mulder BJ, Goumans MJ, Lindeman JH, Jongbloed MR, DeRuiter MC, Klautz RJ, Bogers AJ, Poelmann RE, Groot AC
Patients with bicuspid aortic valve (BAV) and patients with Marfan syndrome (MFS) are more prone to develop aortic dilation and dissection compared to persons with a tricuspid aortic valve (TAV). To elucidate potential common and distinct pathways of clinical relevance, we compared the histopathological substrates of aortopathy. Ascending aortic wall biopsies were divided in five groups: BAV (n = 36) and TAV (n = 23) without and with dilation and non-dilated MFS (n = 8). General histologic featu... Abstract

Annals of medicine, Volume 46, Issue 8, 13 2 2014, Pages 640-652 Morphogenesis and molecular considerations on congenital cardiac septal defects. Gittenberger-de Groot AC, Calkoen EE, Poelmann RE, Bartelings MM, Jongbloed MR
The primary unseptated heart tube undergoes extensive remodeling including septation at the atrial, atrioventricular, ventricular, and ventriculo-arterial level. Alignment and fusion of the septal components is required to ensure full septation of the heart. Deficiencies lead to septal defects at various levels. Addition of myocardium and mesenchymal tissues from the second heart field (SHF) to the primary heart tube, as well as a population of neural crest cells, provides the necessary cellular... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 22, Issue 9, 1 1 2014, Pages 363-369 Normal and abnormal development of the aortic wall and valve: correlation with clinical entities. Grewal N, DeRuiter MC, Jongbloed MR, Goumans MJ, Klautz RJ, Poelmann RE, Gittenberger-de Groot AC
Dilation of the wall of the thoracic aorta can be found in patients with a tricuspid (TAV) as well as a bicuspid aortic valve (BAV) with and without a syndromic component. BAV is the most common congenital cardiovascular malformation, with a population prevalence of 0.5-2 %. The clinical course is often characterised by aneurysm formation and in some cases dissection. The non-dilated aortic wall is less well differentiated in all BAV as compared with TAV, thereby conferring inherent developmenta... Abstract

Cardiology in the young, Volume 24 Suppl 2, 27 4 2014, Pages 3-12 Imaging the first trimester heart: ultrasound correlation with morphology. Jansen FA, Calkoen EE, Jongbloed MR, Bartelings MM, Haak MC
First trimester sonography is a widely used technique to examine the foetus early in pregnancy. The desire to recognise complex anatomy already in early developmental stages stresses the need for a thorough knowledge of basic developmental processes as well as recognition of cardiac compartments based on their morphology. In this paper, we describe the possibilities and limitations of sonographic assessment of the foetal heart between 10 and 14 weeks of gestation and correlate this to morphology... Abstract

Grewal N, Gittenberger-de Groot AC, DeRuiter MC, Klautz RJ, Poelmann RE, Duim S, Lindeman JH, Koenraadt WM, Jongbloed MR, Mohamed SA, Sievers HH, Bogers AJ, Goumans MJ
Objectives: The clinical course of many patients with a bicuspid aortic valve (BAV) is complicated by ascending aortic dilatation. Currently, the indication for aortic surgery is solely based on the aortic diameter and subsequently only a small proportion of BAV patients undergoing valve surgery require concomitant ascending aortic replacement based on these recommendations. Unfortunately, a substantial number of BAV patients still develop aortic dilatation in the future and would potentially be... Abstract
