The authors report the case of a suicide attempt. A 59-year-old man with self-inflicted penetrating chest trauma underwent emergency cardiothoracic surgery. Pre-operative computed tomography scan showed critical proximity between the blade and the right ventricle. Intraoperative findings showed a pericardial laceration and a huge diaphragmatic lesion with heart and abdominal organs integrity. The diaphragm muscle was repaired with a CorMatrix® patch, an acceptable alternative to the traditional synthetic mesh avoiding infection and repeated herniation...

BACKGROUND: The incidence of cardiac implantable electronic device (CIED) infections has risen significantly over the past years. Although several devices are currently available to decrease the incidence of infection, most are made from non-viable synthetic material and are more prone to infection than vascularized tissue. OBJECTIVE: This study was undertaken to assess the resistance to infection of the CorMatrix CanGaroo, a CIED envelope made of decellularised extracellular matrix (ECM) hydrated in different antibiotic solutions...

Coronary sinus injury is a very rare complication of cardiac surgery and is usually related to coronary sinus perfusion catheter placement for retrograde cardioplegia infusion. It can be either a catheter-related perforation or high-perfusion pressure-related injury to the coronary sinus. Primary repair of the coronary sinus or over-sewing are two possible options to resolve this complication. Decellularized extracellular matrix from porcine intestinal submucosa is widely used as an approved material for repairing cardiac structures...

Surgery for congenital valve anomalies in children is a challenging topic. We aim to assess early and late functional outcomes of CorMatrix scaffold after repair of aortic and pulmonary valves (PV) in congenital heart disease in a prospective nonrandomized clinical study on children with congenital aortic (Group 1) or PV (Group 2) disease. Primary endpoints were reoperation or reintervention on semilunar valves and echocardiographic evidence of regurgitation or stenosis greater than mild. Results of PV repair in tetralogy of Fallot were compared with a control group of patients who underwent PV repair with polytetrafluoroethylene...

BACKGROUND: The CorMatrix (CorMatrix Cardiovascular, Roswell, Ga) biologic extracellular patch derived from porcine small intestinal mucosa provides a biologic scaffold for cellular ingrowth and eventual tissue regeneration. It has been used in a variety of applications, including cardiac and vascular repair procedures. METHODS: CorMatrix was used as a patch arterioplasty for femoral artery repair in conjunction with endarterectomy for seven separate procedures in six patients (one patient underwent staged, bilateral femoral procedures)...

OBJECTIVES: Porcine small intestinal submucosa extracellular matrix (CorMatrix; CorMatrix Cardiovascular, Rosewell, GA) is a relatively novel tissue substitute used in cardiovascular applications. We investigated the biological reaction and remodelling of CorMatrix as a tri-leaflet valved conduit in a pig model. We hypothesized that CorMatrix maintains a durable architecture as a valved conduit and remodels to resemble surrounding tissues. METHODS: We fashioned the valved conduit using a 7 × 10 cm 4-ply CorMatrix sheet and placed it in the thoracic aorta of seven landrace pigs for 3, 4, 5 and 6 months...

BACKGROUND: This study reported on the treatment of Carpentier type IIIa and type IIIb mitral regurgitation (MR) with a large patch anterior mitral valve leaflet augmentation technique using CorMatrix (CorMatrix Cardiovascular Inc, Alpharetta, GA) extracellular matrix (ECM). METHODS: A single-site chart review was conducted on patients who underwent anterior leaflet augmentation performed with the Da Vinci surgical robot (Intuitive Surgical, Sunnyvale, CA) or through a median sternotomy...

Background We tested the feasibility of using porcine small intestinal submucosal extracellular matrix (CorMatrix) for aortic valve (AV) repair in porcine model examining its resorption and remodeling potential. Methods The non-coronary cusp was replaced with CorMatrix in four animals for 120 days. Valve function was assessed by echocardiography. Explants were examined by histology, immunohistochemistry, and collagen assessment. Results CorMatrix was almost totally replaced with tissue resembling the native cusp with a partial two-layer architecture...

BACKGROUND: Animal data demonstrate that intracardiac patches of decellularized porcine small intestine submucosa (CorMatrix; CorMatrix Cardiovascular, Inc, Atlanta, GA) become repopulated with native cells, suggesting the possibility of a substrate for regenerative tissue in humans. We report the only prospective series to date of explanted CorMatrix patches placed in infants with congenital heart disease. METHODS: CorMatrix patches were implanted as the hemi-Fontan baffle in patients during their second stage of palliation...

BACKGROUND: Infarcted myocardium can remodel after successful reperfusion, resulting in left ventricular dilation and heart failure. Epicardial infarct repair (EIR) using a bioinductive extracellular matrix (ECM) biomaterial is a novel surgical approach to promote endogenous myocardial repair and functional recovery after myocardial infarction. Using a pre-clinical porcine model of coronary ischemia-reperfusion, we assessed the effects of EIR on regional functional recovery, safety, and possible mechanisms of benefit...

Extracellular matrix (ECM) derived from small intestinal submucosa (SIS) is widely used in clinical applications as a scaffold for tissue repair. Recently, CorMatrix® porcine SIS-ECM (CorMatrix Cardiovascular, Inc., Roswell, GA, USA) has gained popularity for 'next-generation' cardiovascular tissue engineering due to its ease of use, remodelling properties, lack of immunogenicity, absorbability and potential to promote native tissue growth. Here, we provide an overview of the biology of porcine SIS-ECM and systematically review the preclinical and clinical literature on its use in cardiovascular surgery...

A number of materials have been used for the repair of congenital heart disease. However, an ideal material is yet to be discovered. Decellularized extracellular matrix from porcine small intestinal submucosa (CorMatrix) has been developed and commercialized as a biological tissue substitute. This has been used for valvuloplasty, sepal defect repair, or angioplasty as a patch. In this study, we demonstrate our preliminary experience using CorMatrix as a tube graft. A retrospective review of 13 patients who underwent cardiac surgery using CorMatrix as an interposition graft was performed (10 patients for central pulmonary artery reconstruction in comprehensive stage II surgery for hypoplastic left-sided heart syndrome and 3 patients for aortic arch reconstruction in interrupted aortic arch)...

Type IV laryngotracheo-esophageal cleft (LTEC) extending to the level of the carina presents unique challenges to operative repair, particularly with respect to soft tissue durability. This is the first report of CorMatrix(®) extra-cellular matrix (ECM) material use as an interposition graft in a four-layered LTEC repair. At day seven post-operatively, there was epithelialization along the surface of the trachea. At 3 months, she was stable for tracheotomy. At 6 months, the posterior wall resembled completely native tissue...

OBJECTIVE: The treatment of segmental arteriovenous fistula aneurysms (AVFAs) remains a challenge in dialysis access preservation. We examined our experience with the use of tubularized extracellular matrix (ECM; CorMatrix, Roswell, Ga) for AVFA repair. METHODS: Between October 2013 and January 2015, we conducted a prospective study of CorMatrix ECM for AVFA repair. All patients underwent intraoperative fistulography. Patients with central venous stenosis or occlusion had simultaneous angioplasty and stenting as indicated...

BACKGROUND: CorMatrix is a decellularized porcine small intestinal submucosa extracellular matrix that has gained attention as a promising alternative to current materials used in cardiac repair. While animal models demonstrate integration of CorMatrix material with host tissue, the histologic characteristics of CorMatrix used in humans are less well-characterized. In this retrospective study, we report our experience with CorMatrix material used in pediatric congenital heart surgery and describe the histology of CorMatrix material and of surrounding native tissue in explanted specimens...
