Journal ArticleDOI
Low-dose acetyl salicylic acid versus oral anticoagulation after bioprosthetic aortic valve replacement. Final report of the ACTION registry
TL;DR: Compared with ASA, treatment with VKA was associated with higher morbidity within 6 months after bioprosthetic AVR, suggesting that, particularly after concomitant CABG surgery, recipients of biop Frostian aortic valve replacement should receive prophylactic ASA instead of VKA.
Proceedings Article
ROBUST CHARACTERISTIC POINTS FOR ICG - Definition and Comparative Analysis
TL;DR: A computationally simple algorithm, based on high order derivatives, is proposed that enables the identification of the main characteristic points, B and X, with significantly smaller errors and much higher correlations compared to current state of the art methods and existing alternative characteristic point definitions.
Proceedings ArticleDOI
Assessing PEP and LVET from heart sounds: Algorithms and evaluation
Rui Pedro Paiva,Paulo Carvalho,Xavier L. Aubert,Jens Muehlsteff,Jorge Henriques,Manuel J. Antunes +5 more
TL;DR: Estimation of systolic time intervals, namely the pre-ejection period (PEP) and the left ventricular ejection time (LVET), using heart sound supports the assumption that heart sounds can be applied to detect the onset of the aortic valve movement processes.
Journal ArticleDOI
Challenges in rheumatic valvular disease: Surgical strategies for mitral valve preservation.
TL;DR: It is becoming increasingly clear that, although, the results may not compare to those obtained with degenerative pathology, repair of rheumatic valves, when feasible, is the procedure of choice, especially in these underprivileged populations.
Journal ArticleDOI
Diagnostic value of surgical lung biopsy: comparison with clinical and radiological diagnosis.
Gonçalo F. Coutinho,Rita Pancas,Eunice Magalhães,João Bernardo,Luís Eugénio,Manuel J. Antunes +5 more
TL;DR: Despite a high sensitivity and specificity of the clinical and imagiological diagnosis, the positive predictive value was low, particularly in the malignancy group, and surgical lung biopsy should be performed in pulmonary infiltrates of unknown aetiology.
