The New England journal of medicine, Volume 358, Issue 19, 1 1 2008, Pages 2024-2029 Left cardiac sympathetic denervation for catecholaminergic polymorphic ventricular tachycardia. Wilde AA, Bhuiyan ZA, Crotti L, Facchini M, De Ferrari GM, Paul T, Ferrandi C, Koolbergen DR, Odero A, Schwartz PJ
Catecholaminergic polymorphic ventricular tachycardia is a potentially lethal disease characterized by adrenergically mediated ventricular arrhythmias manifested especially in children and teenagers. Beta-blockers are the cornerstone of therapy, but some patients do not have a complete response to this therapy and receive an implantable cardioverter-defibrillator (ICD). Given the nature of catecholaminergic polymorphic ventricular tachycardia, ICD shocks may trigger new arrhythmias, leading to t... Abstract

Journal of the American Society of Echocardiography : official publication of the American Society of Echocardiography, Volume 21, Issue 5, 1 1 2007, Pages 512.e5-7 Iatrogenic perforation of the posterior mitral valve leaflet: a rare complication of pacemaker lead placement. Konings TC, Koolbergen DR, Bouma BJ, Groenink M, Mulder BJ
An inadvertently placed pacing lead in the left ventricle (LV) is a rare and often underdiagnosed complication of pacemaker implantation. We present a case of a 73-year-old woman who was evaluated for dyspnea, 10 years after transvenous pacemaker implantation. Transthoracic and transesophageal echocardiography revealed a secundum atrial septal defect through which the ventricular pacing lead was placed into the LV. Whereas percutaneous extraction of the lead seemed too full of risk, the patient... Abstract

The Annals of thoracic surgery, Volume 84, Issue 2, 1 1 2007, Pages 599-605 Right ventricular outflow tract reconstruction with the bovine jugular vein graft: 5 years' experience with 133 patients. Sekarski N, van Meir H, Rijlaarsdam ME, Schoof PH, Koolbergen DR, Hruda J, von Segesser LK, Meijboom EJ, Hazekamp MG
Background: We analyzed the results in two centers of using bovine jugular vein graft for right ventricular outflow tract reconstruction. Methods: From April 1999 to July 2005, 133 children with a median age of 30.9 months (range, 4 days to 19 years) underwent graft implantation. Echocardiography was performed during follow-up and retrospectively reviewed. Results: Nongraft-related early mortality occurred in 8 patients. Late mortality occurred in 11 patients, 2 late deaths were graft related (e... Abstract

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 22, Issue 5, 1 1 2002, Pages 802-807 Structural degeneration of pulmonary homografts used as aortic valve substitute underlines early graft failure. Koolbergen DR, Hazekamp MG, de Heer E, van Hoorn F, Huysmans HA, Bruijn JA, Dion RA
Objectives: The limited availability of donor valves and experimental evidence that pulmonary valves can withstand systemic pressure made us use cryopreserved pulmonary homografts as aortic valve substitutes. We observed a high incidence of early reoperation because of severe graft insufficiency due to cuspal tears. The mid-term results are evaluated in this study and histological analysis of explanted homografts is performed to investigate the cause of graft failure. Methods: From December 1991... Abstract

The Journal of thoracic and cardiovascular surgery, Volume 124, Issue 4, 1 1 2002, Pages 689-697 The pathology of fresh and cryopreserved homograft heart valves: an analysis of forty explanted homograft valves. Koolbergen DR, Hazekamp MG, de Heer E, Bruggemans EF, Huysmans HA, Dion RA, Bruijn JA
Objective: Tissue degeneration reduces the durability of aortic and pulmonary homograft heart valves. Homograft valves can evoke cellular and humoral immune responses that might be detrimental to the valve tissue. Analyzing explanted homograft valves helps in understanding the different factors that eventually lead to tissue degeneration. Methods: A total of 40 homografts was acquired from patients whose grafts had been explanted because of stenosis (n = 22), insufficiency (n = 8), paravalvular... Abstract

The Annals of thoracic surgery, Volume 66, Issue 6 Suppl, 1 1 1998, Pages S225-32 Tissue chimerism in human cryopreserved homograft valve explants demonstrated by in situ hybridization. Koolbergen DR, Hazekamp MG, Kurvers M, de Heer E, Cornelisse CJ, Huysmans HA, Bruijn JA
Background: The presence of viable cells may contribute to increased homograft valve durability. These cells may be of infiltrating recipient or persisting donor origin. In this study, in situ hybridization was used to assess the origin of cells in cryopreserved homograft valve explants. Methods: A total of 10 homografts with a donor-recipient gender mismatch were acquired from patients whose graft had been explanted at reoperation or at autopsy. The period of implantation varied from 14 days to... Abstract

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

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
