Aortic valve endocarditis may be destructive and cause an acquired Gerbode-type defect. The use of biological material in the closure of the Gerbode defect and reconstruction of the aortic valve is essential for both early and long-term survival. Herein, we present a 62-year-old male patient whose Gerbode defect was repaired with bovine pericardium. Additionally, the aortic valve was reconstructed by using bovine pericardium with Ozaki neocuspidization technique.

CONCLUSIONS: ARE during surgical AVR can be safely performed without an increase in complications with excellent early and intermediate-term survival.

Cryopreserved vein allografts are used as alternative conduits for infrainguinal bypass but are prone to aneurysmal degeneration. A 60-year-old man presented with a pulsatile, tender right groin mass 2 years after thrombosis of a cryopreserved vein jump graft emanating from a prosthetic axillary to profunda bypass. Intraoperatively, the aneurysm was consistent with isolated dilatation of the hood of the thrombosed cryopreserved vein graft. This was excised and repaired with bovine pericardial...

Leiomyosarcoma of the pulmonary artery is a rare but potentially fatal disease. Due to its rarity, the treatment algorithm is not well-established. While there may be a role for both chemotherapy and radiotherapy, surgical management is the most definitive method. Unfortunately, when the disease process is advanced, surgery may not be curative. However, it may still be a palliative treatment option. In this case report, we present a patient who suffered from respiratory symptoms that were...

CONCLUSION: We are of the opinion that the PAC method is effective and safe for carotid artery closure in patients undergoing CEA.

CONCLUSION: None of the analyzed tissues resembled the exact structure of the autologous pericardial explant. Degeneration of pericardium starts during industrial processing, suggesting a potential harm on graft longevity in children. A careful surgical approach prior to the implantation of xenografts is therefore needed.

CONCLUSION: Decellularized bovine pericardial patches loaded with adipose-derived and cultured mesenchymal stromal cells enhanced healing in terms of both histology and mechanical strength at 8 weeks following rotator cuff repair in a rat model.

CONCLUSIONS: Although no children had high levels of antibodies to TKO RBCs, 13/14 demonstrated antibodies to TKO PBMCs, in 6 of these showed mild cytotoxicity. As no adults had cytotoxic antibodies to TKO PBMCs, the higher incidence in children may possibly be associated with their exposure to previous cardiac surgery and biological products. However, the numbers were too small to determine the influence of such past exposures. Before considering pig heart xenotransplantation for children with...

CONCLUSIONS: The TTM-AMLE is a safe and effective surgical approach for selected patients with HOCM. In our series, it provides excellent relief of left ventricular outflow tract obstruction, while significantly eliminating mitral regurgitation. The early outcomes of TTM-AMLE are satisfactory, but further studies and longer follow-ups are awaited.

Percutaneous closure of atrial septal defect (ASD) has emerged as a feasible alternative strategy to surgical repair in many cardiac centers worldwide. Occluder recanalization due to device failure is a rare and severe complication that often occurs within weeks to years after ASD closure. We reported a rare ultra-long-term complication of occluder recanalization due to delayed spontaneous perforation of polyvinyl alcohol (PVA) membrane of ASD occluder after 18 years of ASD closure. Surgical...
