A 31-year-old male patient underwent a heart transplantation due to dilated cardiomyopathy. He experienced accelerated acute antibody-mediated rejection despite being negative for human leukocyte antigen antibodies (0% panel-reactive antibodies prior to surgery). Further assessment revealed a common antigen between a homograft implanted 17 years earlier during the Ross procedure and the heart donor. The homograft likely induced specific antibody formation. Interestingly, panel-reactive antibody levels measured 7 years prior to transplantation were 7%...

OBJECTIVE: Our institution uses a valved polytetrafluoroethylene conduit as an alternative to homografts. The objective of this study was to investigate the performance of bicuspid valved polytetrafluoroethylene conduits used for right ventricular outflow tract reconstruction in children aged less than 2 years and to evaluate risk factors for earlier conduit explant. METHODS: We performed an Institutional Review Board-approved retrospective chart review of all patients aged less than 2 years who underwent surgical right ventricular outflow tract reconstruction with a bicuspid valved polytetrafluoroethylene conduit or homograft conduit from July 2004 to December 2014...

BACKGROUND: We analysed outcomes of IAA repair using a standardised technique in order to interpret the role of the arch repair on late outcomes in this complex and heterogeneous group. METHODS: Single institution study from 1988-2015. 120 cases of IAA were divided into four groups: IAA with VSD (iVSD, n=38), IAA with Norwood/DKS (iNor, n=41), IAA with Truncus (iTruncus, n=24) and miscellaneous group (iMisc, n=17). Arch repair performed using a standard technique of direct anastomosis with homograft patch augmentation...

Pseudoaneurysm (PSA) is a known but rare complication of the right ventricle to pulmonary artery (RV-PA) conduits. The patient's clinical presentation can be variable ranging from asymptomatic to potential rupture. We describe an unusual case of a massive PSA in an infant who underwent RV-PA pulmonary homograft placement after relief of right ventricular outflow tract obstruction.

Patients with double-inlet left ventricle usually have a small ascending aorta. In the Norwood procedure, which involves a staged operation, a neoaorta is constructed with a homograft, and the pulmonary artery plays a role in the systemic circulation. Dilatation or aneurysmal changes can occur over time due to the exposure of the neoaorta to systemic pressure, which may induce adverse effects on adjacent structures. We report a rare case of surgical repair for neoaortic root dilataiton with aortic regurgitation, compressing the left pulmohary artery, in a patient who underwent the Norwood procedure...

OBJECTIVE: Repair of truncus arteriosus often requires early right ventricular outflow tract (RVOT) re-operation. Using a modified repair the branch pulmonary arteries are left in-situ, which may avoid earlier RVOT reoperation. We hypothesized that our modified repair for Type I and II truncus arteriosus would extend the time to RVOT re-operation. METHODS: Infants with truncus arteriosus were divided into two groups: A) Traditional technique where the branch pulmonary arteries are excised from the truncal root, or B) Modified repair where the branch pulmonary arteries are left in-situ and septated from the truncal root...

OBJECTIVE: Single-length saphenous vein continues to be the conduit of choice in infected-field critical limb ischemia (CLI). However, half of these individuals have inadequate vein secondary to previous use or chronic venous disease. We reviewed our outcomes of infected-field infrainguinal bypasses performed with cryopreserved homografts (CH), a widely-accepted alternative to autogenous vein in this setting. METHODS: This is a retrospective, institutional descriptive analysis of infected-field infrainguinal revascularizations between 2012-2015...

BACKGROUND: Patients who undergo the Ross procedure are at increased risk of pulmonary valve (PV) homograft dysfunction. For those who require reintervention on the homograft, transcatheter PV replacement (tPVR) provides a less invasive therapeutic option than surgical PVR (sPVR). We examined the outcomes following tPVR versus sPVR in a cohort of patients who underwent the Ross procedure. METHODS: We performed a retrospective analysis of Ross patients age ≥14 years who underwent tPVR (n = 47) or sPVR (n = 41) at our institution...

Livers removed during transplant hepatectomies could represent a useful anatomic ex vivo resource for surgical training, since they are intact and not altered by post-mortem changes yet. The aim of this study is to investigate the effectiveness of such kind of surgical training applied on some hepatic surgery techniques. In the present paper, we focused on split liver operation and middle hepatic vein (MHV) bipartition/reconstruction, since these procedures have a quite long learning curve. Seven native livers were submitted to split liver procedure by a senior resident assisted by a fully trained hepatic surgeon...

Intestinal transplantation in children has evolved with more isolated small intestine transplants being performed compared to combined liver-intestine transplants. Consequently, surgical techniques have changed, frequently requiring the use of vascular homografts of small caliber to revascularize the isolated small intestine, the impact of which on outcomes is unknown. Among 106 pediatric intestine and multivisceral transplants performed at our center since 2003, 33 recipients of an isolated small intestine graft were included in this study...

BACKGROUND: Repair of congenital heart defects involving the right ventricular outflow tract may require the implantation of a right ventricle to pulmonary artery conduit. This conduit is likely to be replaced during childhood. This study compares the operative outcomes of the replacement procedure of Contegra® and homografts in pulmonary position. METHODS: From 1999 to 2016, 82 children underwent 87 right ventricle to pulmonary artery conduit replacements (60 Contegra® and 27 homografts)...

The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (ContegraR ) graft (31 patients)...

A right aortic arch with an isolated left innominate artery from the left patent ductus arteriosus is a rare arch anomaly, and establishing continuity between the innominate artery and aorta can be challenging. We describe repair of this lesion in a three-week-old male using an autologous pedicle flap of ascending aorta as well as a homograft patch as the roof to recreate continuity between the aorta and left innominate artery.

We describe three patients with severe aortic regurgitation after aortic root replacement using the Medtronic Freestyle® bioprosthesis. In two cases, the indication was endocarditis. The third case showed rupture of the right coronary cusp. To achieve fewer complications, lower operative risk and save operative and cross-clamp times, implantation of a sutureless bioprosthesis in a valve-in-valve manner was performed. In two cases, a Perceval bioprosthesis and in the other case, a 3f-Enable bioprosthesis were used...

Patients with connective tissue disorder present a particular clinical challenge in the treatment of aortic graft infections. Specific complexities arise in patients with connective tissue disorders when reoperation for aortic graft infection is required. Herein we describe current management of infected aortic grafts in patients with connective tissue disorders using homograft and rifampin-coated graft replacements using in situ replacement therapy, which is associated with improved outcome compared to graft excision and extra-anatomic bypass...

Background: Mycotic aortic aneurysms are rare and life-threatening. Unfortunately, no established guidelines exist for the treatment of patients with mycotic aortic aneurysms. The purpose of this study was to evaluate the midterm outcomes of the open repair of mycotic thoracic and thoracoabdominal aneurysms and suggest a therapeutic strategy. Methods: From 2006 to 2016, 19 patients underwent open repair for an aortic aneurysm. All infected tissue was extensively debrided and covered with soft tissue...

OBJECTIVE: Palliation of hypoplastic left heart syndrome with a standard nonvalved right ventricle to pulmonary artery conduit results in an inefficient circulation in part due to diastolic regurgitation. A composite right ventricle pulmonary artery conduit with a homograft valve has a hypothetical advantage of reducing regurgitation, but may differ in the propensity for stenosis because of valve remodeling. METHODS: This retrospective cohort study included 130 patients with hypoplastic left heart syndrome who underwent a modified stage 1 procedure with a right ventricle to pulmonary artery conduit from 2002 to 2015...

Outcomes of ACR after pediatric HTx have been well described, but less has been reported on outcomes of AMR. We compared the clinical characteristics and cardiovascular outcomes (composite end-point of death, retransplantation, or allograft vasculopathy) of pediatric HTx recipients with AMR, ACR, and no rejection in a retrospective single-center study of 104 recipients. Twenty were treated for AMR; 15 were treated for ACR. Recipients with AMR had an increased frequency of congenital heart disease (90% vs ACR 67% vs no rejection 59%, P = ...
