Conduction Disorders And Their Clinical Impact After Sutureless/Rapid Deploymen...
Ferreira, Ricardo; Figueiral, Marta; Sena, André; Pereira, Filipe; Junqueira, Nádia; Velho, Tiago; Almeida, Ana; Nobre, Angelo; Pinto, FaustoIntroduction: Aortic stenosis remains the number one heart valve pathology. The drive to improve the surgical outcomes brought to focus rapid deployment valves (RDV), which reduce aortic cross-clamping and cardio-pulmonary bypass (CPB) times. However, some centers have reported a higher rate of conduction abnormalities and permanent pacemaker (PPM) implantation. The aim of this study was to investigate the inci...
Sutureless bioprosthesis for aortic valve replacement: surgical and clinical ou...
Ferreira, Ricardo; Rua, Nuno; Sena, André; Velho, Tiago R.; Goncalves, Joao; Junqueira, Nádia; Almeida, Ana G.; Nobre, Angelo; Pinto, Fausto J.Background: Aortic valve stenosis is the most common adult valve disease in industrialized countries. The aging population and the increase in comorbidities urge the development of safer alternatives to the current surgical treatment. Sutureless bioprosthesis has shown promising results, especially in complex procedures and in patients requiring concomitant surgeries. Objectives: Assess the clinical and hemodyn...
Role of omega-6 fatty acid metabolism in cardiac surgery postoperative bleeding...
Velho, Tiago R.; Ferreira, Ricardo; Willmann, Katharina; Pedroso, Dora; Paixão, Tiago; Pereira, Rafael Maniés; Junqueira, Nádia; Carvalho Guerra, NunoCardiac surgery is frequently associated with significant postoperative bleeding. Platelet-dysfunction is the main cardiopulmonary bypass (CPB)-induced hemostatic defect. Not only the number of platelets decreases, but also the remaining are functionally impaired. Although lipid metabolism is crucial for platelet function, little is known regarding platelet metabolic changes associated with CPB-dysfunction. Our...
GIANT PLEURAL TUMOR AND SEVERE HYPOGLYCEMIA: DOEGE-POTTER SYNDROME IN A PREVIOU...
Junqueira, Nádia; Caldeira, João; Ferreira, Ricardo; Costa, Filipe; Silva, Joana; Monteiro, Teresa; Nobre, ÂngeloIntroduction: Doege–Potter’s syndrome is a rare paraneoplastic syndrome, consisting in hypoglycemia and solitary fibrous tumor of the pleura. These tumors represent <5% of all pleural tumours and can only be cured by surgery. In this article, we report a case of a patient presenting with severe hypoglycemia, as the only symptom, and a mass occupying the entire left hemithorax. Case presentation: A54 year old...
COMBINED PERICARDIECTOMY AND BEATING HEART CORONARY ARTERY BYPASS GRAFTING
Junqueira, Nádia; Ferreira, Ricardo; Bernardo, Ricardo; Nobre, Ângelo50-years-old male with three vessels coronary lesions. Intraoperatively thickened constrictive pericardium with multi-loculated hematic effusion. Ante-phrenic pericardiectomy was performed and the heart released posteriorly, allowing mobilization. Off-pump LITA to LAD and SVG to PD anastomosis were performed. Post-operative uneventful. Histology confirmed chronic, idiopathic inflammation. A rare and challenging...
INFECTIVE ENDOCARDITIS AFTER TRANSCATHETER AORTIC VALVE IMPLANTATION
Junqueira, Nádia; Ferreira, Ricardo; Gonçalves, João; Nobre, Ângelo; Ricardo, InêsIntroduction: Transcatheter aortic valve implantation has emerged as an effective alternative to the traditional method of surgical aortic valve replacement in high risk or inoperable patients. Infective endocarditis after transcatheter aortic valve implantation is a post-operative complication with a high rate of mortality, and thus far, very few cases of successful surgery have been reported. Case presentatio...
Platelet count drop after rapid deployment aortic valve implantation
Sena, André; Ferreira, Ricardo; Nobre, Mariana; Ferreira, Hugo; Junqueira, Nádia; Velho, Tiago; Silva, Joana; Gonçalves, João; Guerra, NunoBackground: A transient postoperative drop in platelet count is an expected finding after aortic valve replacement using extracorporeal circulation. The implantation of the Perceval valve has been associated with a more intense drop of platelet count compared to other bio-prostheses. This study analyses and compares the platelets progression associated with the Perceval and Intuity valves. Methods: The data was...

Aortic dissection repair using the STABILISE technique associated with arch pro...
Lopes, Alice; Melo, Ryan; Gomes, Miguel L.; Garrido, Pedro; Junqueira, Nádia; Sobrinho, Gonçalo; Fernandes E Fernandes, Ruy; Leitão, João; Nobre, ÂngeloIntroduction: The stent assisted balloon induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique is being increasingly used for the treatment of complicated aortic dissections. However, as it is a fairly recent technique, the scientific information is limited. Report: In this paper we report two cases of the STABILISE technique associated with procedures in the ascending ao...
