CardioCel® for repair of congenital heart defects: nationwide results of over 1000 implants. Eur J Cardiothorac Surg 2023; 64:ezad343. [PMID: 37846036 DOI: 10.1093/ejcts/ezad343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 09/09/2023] [Accepted: 10/13/2023] [Indexed: 10/18/2023] Open
Abstract
OBJECTIVES To assess the mid-term performance of CardioCel for the repair of congenital heart defects. METHODS Data were retrospectively collected from databases and hospital records in 3 congenital cardiac surgery centres in Australia. Kaplan-Meier curves and log-rank tests were used to test for associations between patient age, gender, patch type and site of implantation. Multivariable Cox regression was used to test whether any specific implantation site was associated with reintervention risk, after adjusting for age group, gender and patch type. RESULTS A total of 1184 CardioCel patches were implanted in 752 patients under the age of 18 years. Median age at implant was 12 months [interquartile range (IQR) 3.6-84]. Median follow-up was 2.1 years (IQR 0.6-4.6). Probability of freedom from CardioCel-related reintervention was 93% [95% confidence interval (CI) 91-95] at 1 year, 91% (95% CI 88-93) at 3 years and 88% (95% CI 85-91) at 5 years, respectively. On multivariable regression analysis, aortic valve repair had a higher incidence of reintervention [hazard ratio (HR) = 7.15, P = 0.008] compared to other sites. The probability of reintervention was higher in neonates (HR = 6.71, P = 0.0007), especially when used for augmentation of the pulmonary arteries (HR = 14.38, P = 0.029), as compared to other age groups. CONCLUSIONS CardioCel can be used for the repair of a variety of congenital heart defects. In our study, in patients receiving a CardioCel implant, reinterventions were higher when CardioCel was used to augment the pulmonary arteries in neonates and for aortic valve repair as compared to other sites.

Abstract
A systematic review was performed for evaluation of the performance of CardioCel® in cardiac surgery. The review included all studies published from January 2013 to December 2020. We conclude that CardioCel is a strong, flexible tissue substitute with good handling characteristics and a low incidence of thrombosis, aneurysm formation, infection, or structural degeneration. It can be used for a variety of intracardiac and extracardiac repairs of congenital heart defects in all age groups with good durability at mid-term follow-up. However, the use of CardioCel in certain positions requires caution. Information on the long-term performance of CardioCel is lacking.

ADAPT-treated pericardium for aortic valve reconstruction in congenital heart disease: histological analysis of a series of human explants. Eur J Cardiothorac Surg 2019; 56:1170-1177. [DOI: 10.1093/ejcts/ezz228] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 06/26/2019] [Accepted: 07/15/2019] [Indexed: 12/22/2022] Open
Abstract
Abstract
OBJECTIVES
Different types of patch materials are used for aortic valve repair in children with congenital aortic valve disease to avoid early valve replacement. CardioCel© (Admedus, Toowong, QLD, Australia) consists of bovine pericardium treated with the ADAPT method (Admedus’ proprietary tissue engineering process).
METHODS
Our goal was to describe tissue reactions in 12 explanted aortic valve leaflet specimens (augmented or replaced with CardioCel patch material) (11 explanted surgically, 1 autopsy). Explantation was performed during reoperation after aortic valve repair, necessitated by aortic valve stenosis in 5, aortic valve insufficiency in 2, combined aortic valve lesions in 3 patients and endocarditis in 1 patient. One patient died of sudden left heart failure 28 months after aortic valve repair. At the last documented follow-up of this patient at 22 months, he showed mild aortic valve stenosis and insufficiency. Implantation time (time between implantation and explantation) of CardioCel patches was a median of 25 (range 11–47) months. Explants were examined using a uniform protocol with methylmethacrylate and/or paraffin embedding after fixation in formalin. Besides standard histological staining, von Kossa (for identification of calcifications) and immunohistochemical stains were applied with antibodies specific for muscular, inflammatory and connective tissue component antigens. Findings regarding the extent of appositional growth on top of the patch consisting of fibroblasts and extracellular matrix components, calcification, and inflammation were rated using a 4-grade scale (G0 no/G1 few/G2 moderate/G3 massive).
RESULTS
Superficial endothelialization was demonstrated in all patients by immunohistochemical analysis. Nine specimens showed mild inflammatory cell infiltration (G1) (G2: n = 3). Significant appositional growth on top of the patch due to addition of fibroblasts and extracellular matrix components, was seen in all specimens (G1: n = 1; G2: n = 7; G3: n = 4). Ten of 12 samples with implant times of 23 months or longer revealed calcifications (G1: n = 6; G2: n = 3; G3: n = 1). Two specimens with the shortest implant times (11 and 20 months) showed no calcifications (G0). Thrombus apposition with granulocyte infiltration was demonstrated in the specimen of the patient with endocarditis.
CONCLUSIONS
In our cohort, all CardioCel patches used for aortic valve repair in patients with congenital heart disease demonstrated appositional growth of fibroblasts and extracellular matrix components, and calcification after an implant time of at least 23 months.
