Predicting the burden for surgical aortic valve replacement in a tertiary centr...
Pereira, Rafael Maniés; Carvalho Guerra, Nuno; Moreira Gonçalves, João; Ferreira, Ricardo; Nobre, Angelo; Brito, Dulce; Rodrigues, Teresa FerreiraBackground/Objectives: The incidence of aortic stenosis (AS) is predicted to rise with the aging population, emerging as a growing public health challenge in developed countries, leading to an increased demand for intervention. Our aim is to predict the evolution of proposed cases for SAVR in the geographic referral area of our tertiary hospital until 2041. Methods: We used data from the Portuguese Census for 2...
Growth differentiation factor 15 as a biomarker for risk stratification in the ...
Ferreira, Ricardo; Velho, Tiago R.; Pereira, Rafael Maniés; Pedroso, Dora; Draiblate, Beatriz; Santos, Susana Constantino Rosa; Nobre, AngeloGrowth Differentiation Factor 15 (GDF15) is an emerging biomarker that significantly increases during acute stress responses, such as infections, and is moderately elevated in chronic and inflammation-driven conditions. While evidence suggests that high levels of GDF15 in cardiac surgery are associated with worse outcomes, its utility as an evaluator of early postoperative complications remains unclear. This st...
Post-cardiotomy bronchopericardial fistula
Ângelo, Eurdice; Ferreira, Ricardo; Velho, Tiago R.; Nobre, AngeloWe report a case of a 65 years-old woman submitted to an aortic and mitral valve replacement with mechanical prosthesis (St Jude 19mm and St Jude 21mm, respectively), who developed a postoperative cardiogenic shock, with necessity of mechanical support with extracorporeal membrane oxygenation and intra-aortic pump balloon.
Surgical aortic valve replacement in octogenarians: single-center perioperative...
Velho, Tiago R.; Goncalves, Joao; Pereira, Rafael Maniés; Ferreira, Ricardo; Sena, André; Junqueira, Nádia Viviana; Ângelo, EurídiceIntroduction and objectives: Aortic stenosis is the most common valvular heart disease. The number of octogenarians proposed for intervention is growing due to increased lifespan. In this manuscript we aim to evaluate perioperative outcome and long-term survival after surgical aortic valve replacement (SAVR) in octogenarians, comparing patients with low surgical risk (EuroscoreII <4%) with intermediate-high ris...
The evolution of management of type B aortic dissection in a series of 100 cons...
Lopes, Alice; Pedro, Luís M; Melo, Ryan; Moutinho, Mariana; Sobrinho, Gonçalo; Amorim, Pedro; Silvestre, Luís; Fernandes E Fernandes, RuyIntroduction and objectives: Management of aortic dissection is rapidly evolving. The present study aims to assess paradigm shifts in type B aortic dissection (TBAD) treatment modalities and their outcomes according to clinical presentation and type of treatment. We also aim to assess the impact of endovascular technology in TBAD management in order to define organizational strategies to provide an integrated c...
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...
A common finding with an atypical (rare) presentation
Rigueira, Joana; Cunha, N.; Ferreira, R.; Rodrigues, M.; Silva, J.; Junqueira, N.; Nobre, Angelo; Pinto, Fausto J.; Almeida, Antonio Bugalho deHypereosinophilic syndrome (HES) is characterized by persistent eosinophilia and eosinophil-mediated organ damage. Cardiac thrombosis and thromboembolic complications are common causes of morbidity and mortality in these patients. The echocardiogram is the first method of image in the assessment of cardiac involvement by HES.
