The Annals of thoracic surgery, Volume 79, Issue 6, 1 1 2005, Pages 2147-2149 Double bioprosthetic valve replacement in right-sided carcinoid heart disease. Voigt PG, Braun J, Teng OY, Koolbergen DR, Holman E, Bax JJ, Smit VT, Dion RA
A patient with tricuspid and pulmonary regurgitation due to carcinoid syndrome successfully underwent double bioprosthetic valve replacement. This technique avoids anticoagulation treatment in a patient with hepatic dysfunction and facilitates future hepatic de-arterialization as a treatment option in carcinoid disease. Advances in treatment of carcinoid syndrome may have reduced the risk of early bioprosthetic degeneration. Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 27, Issue 5, 1 1 2005, Pages 847-853 Preoperative left ventricular dimensions predict reverse remodeling following restrictive mitral annuloplasty in ischemic mitral regurgitation. Braun J, Bax JJ, Versteegh MI, Voigt PG, Holman ER, Klautz RJ, Boersma E, Dion RA
Objective: Ischemic mitral regurgitation can be treated with a restrictive mitral annuloplasty, with or without coronary revascularization. In this study, the extent of reverse remodeling of the left ventricle following this strategy is assessed, as well as the factors that influence it. Methods: Eighty-seven consecutive patients with ischemic mitral regurgitation and a mean ejection fraction of 32+/-10% underwent restrictive mitral annuloplasty (downsizing by two ring sizes, median ring size 26...

Circulation, Volume 110, Issue 11 Suppl 1, 1 1 2004, Pages II103-8 Restrictive annuloplasty and coronary revascularization in ischemic mitral regurgitation results in reverse left ventricular remodeling. Bax JJ, Braun J, Somer ST, Klautz R, Holman ER, Versteegh MI, Boersma E, Schalij MJ, van der Wall EE, Dion RA
Background: Data on combined coronary artery bypass grafting (CABG) and restrictive annuloplasty in patients with ischemic cardiomyopathy are scarce, and the effect on reverse left ventricular (LV) remodeling is unknown. Methods and results: 51 patients with ischemic LV dysfunction (LV ejection fraction 31+/-8%) and severe mitral regurgitation (grade 3 to 4+) underwent CABG and restrictive annuloplasty with stringent downsizing of the mitral annulus (by 2 sizes, Physio-ring, mean size 28+/-2).

The Annals of thoracic surgery, Volume 77, Issue 3, 1 1 2004, Pages 794-9; discussion 799 Long-term follow-up of coronary artery bypass grafting in three-vessel disease using exclusively pedicled bilateral internal thoracic and right gastroepiploic arteries. Tavilla G, Kappetein AP, Braun J, Gopie J, Tjien AT, Dion RA
Background: Considerable data now exist that show that coronary artery bypass grafting with bilateral internal thoracic artery (ITA) grafts produce better outcomes than the use of a single ITA graft. The benefit of a third arterial graft has been less well established. Therefore this article describes the survival and cardiac-related event-free survival in patients having bilateral ITA and gastroepiploic artery (GEA) grafting for 3-vessel disease. Methods: From November 1992 to May 2002, 201 pat... Abstract

International journal of cardiac imaging, Volume 16, Issue 5, 1 1 2000, Pages 359-364 Stentless bioprostheses have ideal haemodynamics, even in the small aortic root. Baur LH, Houdas Y, Peels KH, Braun J, van Straten B, Prat A, Kappetein AP, Wolters-Geldoff M, van der Wall EE, Bruschke AV, Huysmans HA
Objective: To determine normal Doppler and 2D gradients and flow characteristics of the Freestyle stentless aortic bioprosthesis related to valve size. Background: The Freestyle stentless aortic bioprosthesis is one of the newer aortic xenografts. Only limited data are available of the echocardiographic flow characteristics during a mid-term follow-up period of this valve. Therefore valve performance related to valve size was measured during a follow-up period of two years. Methods: 175 consecut... Abstract
Echocardiography (Mount Kisco, N.Y.), Volume 17, Issue 7, 1 1 2000, Pages 625-629 Echocardiographic imaging of stentless aortic valve prostheses. Baur LH, Peels K, Braun J, Kappetein AP, Bootsma M, Van Der Ploeg A, Sieders A, Hazekamp M, Van Der Wall EE, Huysmans HA
Unlabelled: Homografts and stentless xenografts are increasingly used in aortic valve surgery. Echocardiography technicians and cardiologists have to know what they will find when performing an echo-Doppler examination in patients who received a stentless valve. We therefore evaluated echocardiographic images of 74 patients who received a Freestyle stentless bioprosthesis with three techniques and a follow-up of 2 years in two high-volume hospitals. Of the patients studied, 81% were operated usi... Abstract

The objective of this study was to determine normal Doppler and 2-dimensional characteristics of the Freestyle stentless aortic bioprosthesis. The Freestyle aortic bioprosthesis is a new type of aortic xenograft, and experience is limited. We therefore determined the normal range of echocardiographic and Doppler examinations of this valve. Three hundred thirty-nine consecutive patients with a Freestyle aortic bioprosthesis underwent an echocardiographic and Doppler examination according to a com... Abstract

In the early nineties, the stentless porcine aortic bioprosthesis has been reintroduced successfully. Because of the limited experience, knowledge of clinical complications is limited. Therefore, we describe an unusual complication of dynamic obstruction after aortic valve replacement with a stentless porcine valve in a 70 year old man 18 months after implantation. We discuss the complications of stentless aortic prostheses known so far, describe operative techniques used and their characteristi... Abstract

Background and aims of the study: Aortic valve disease in the pediatric population poses special problems to surgeons and cardiologists. The pulmonary autograft has proven to be a good alternative for aortic valve replacement and left ventricular outflow tract (LVOT) reconstruction in this special group. Methods: Forty-one children (mean age 10.0 +/- 4.8 (SD) years; range: 35 days to 18.8 years) underwent aortic root replacement with a pulmonary autograft between February 1994 and April 1998. Tw...

The Journal of pathology, Volume 183, Issue 1, 1 1 1997, Pages 99-104 Identification of host and donor cells in porcine homograft heart valve explants by fluorescence in situ hybridization. Braun J, Hazekamp MG, Koolbergen DR, Sugihara H, Goffin YA, Huysmans HA, Cornelisse CJ
The pathogenesis of the primary tissue degeneration that limits the life-span of aortic and pulmonary homografts has still not been revealed. Histopathological studies on homograft explants have not given definitive insight into the eventual fate of donor cells, nor have they demonstrated the assumed importance of host cell ingrowth into the graft tissue. In this experimental study, fluorescence in situ hybridization (FISH) is introduced as a new approach to examine the distribution of host and... Abstract

In a 38-year-old woman who was hospitalized because of hypertension and hypokalaemic alkalosis, the intake of liquorice (200 g per day) was proven to be the cause. A liquorice provocation test produced all the expected clinical and biochemical abnormalities. Some kinds of liquorice contain glycyrrhetic acid which inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase (e.g. in the kidney) leading to decreased transformation of cortisol into cortisone. The mineralocorticoid action of cortisol ca... Abstract

The Journal of thoracic and cardiovascular surgery, Volume 110, Issue 1, 1 1 1995, Pages 248-257 In situ hybridization: a new technique to determine the origin of fibroblasts in cryopreserved aortic homograft valve explants. Hazekamp MG, Koolbergen DR, Braun J, Sugihara H, Cornelisse CJ, Goffin YA, Huysmans HA
Tissue degeneration reduces the durability of cryopreserved homografts. Earlier studies indicated that the presence of fibroblasts in homograft leaflets may contribute to increased valve longevity. These fibroblasts may be of recipient origin or represent surviving donor cells. We developed a method, based on in situ hybridization, to determine the origin of fibroblasts in homograft explants. In young pigs we performed aortic valve replacement with a cryopreserved porcine aortic homograft. A mal... Abstract
