Short and long-term clinical impact of transcatheter aortic valve implantation ...
Guerreiro, Cláudio; Ferreira, Pedro Carrilho; Teles, Rui Campante; Braga, Pedro; Canas da Silva, Pedro; Patrício, Lino; Silva, João CarlosIntroduction: The Portuguese National Registry of Transcatheter Aortic Valve Implantation records prospectively the characteristics and outcomes of transcatheter aortic valve implantation (TAVI) procedures in Portugal. Objectives: To assess the 30-day and one-year outcomes of TAVI procedures in Portugal. Methods: We compared TAVI results according to the principal access used (transfemoral (TF) vs. non-transfem...
The CTo-aBCDE score : a new predictor of success in chronic total occlusions
Rigueira, Joana; Aguiar-Ricardo, Inês; Menezes, Miguel Nobre; Santos, Rafael; Rodrigues, Tiago; Cunha, Nelson; Francisco, Ana RitaIntroduction: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score. Methods: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded. Li...
Transradial left ventricular endomyocardial biopsy feasibility, safety and clin...
Menezes, Miguel Nobre; Oliveira, Eduardo Infante de; Silva, Artur Costa e; Brito, Dulce; Coutinho, Maria Conceição Azevedo; Canas da Silva, PedroIntroduction and objectives: Over the last decade, several studies have suggested that left ventricular endomyocardial biopsy is safer and has a higher diagnostic yield than transvenous right ventricular biopsy. In addition, recent publications indicate that the transradial approach is a feasible and safe alternative to the transfemoral approach for sampling the left ventricle. We report our initial experience ...
One stent versus two stents for distal LM PCI: insights from the experience of ...
Santos, R.; Menezes, Miguel Nobre; Carrilho-Ferreira, Pedro; Calhaz-Jorge, Carlos; Francisco, A. R.; Oliveira, Eduardo Infante de; Duarte, J.Distal left main (LM) PCIremains a challenge. One of the most debated issues is whether to use a single vs 2 stent provisional strategy. While most studies and guidelines favour a single stent strategy, the recent DK-CRUSH V trial has shown better results with a 2 stent strategy.
Adjuvant antithrombotic therapy in ST-elevation myocardial infarction : contemp...
Caldeira, Daniel; Pereira, Hélder; Marques, Ana; Alegria, Sofia; Calisto, João; Canas da Silva, Pedro; Ribeiro, Vasco Gama; Silva, João CarlosIntroduction: The standard of care for acute ST-elevation myocardial infarction (STEMI) includes the activation of a STEMI care network, the administration of adjuvant medical therapy, and reperfusion through primary percutaneous coronary intervention (PCI). While primary PCI is nowadays the first option for the treatment of patients with STEMI, antithrombotic therapy, including antiplatelet and anticoagulant a...
Epidemiological characterization of a population with MINOCA
Santos, R. P.; Gonçalves, I. Santos; Agostinho, João R.; Nunes-Ferreira, Afonso; Cunha, N.; Rodrigues, T.; Rigueira, Joana; Aguiar-Ricardo, InêsIntroduction: Myocardial infarction with non-obstructive coronary arteries (MINOCA) accounts for 1–14% of all infarctions and represents an entity clinically defined by the presence of universal criteria for acute coronary syndrome, absence of obstructive coronary artery disease (OCD) (≥50% stenosis), with no other obvious cause for the clinical presentation. The clinical characteristics and prognosis of these ...
iFR diagnostic accuracy using FFR as gold standard : insights from a 5-year exp...
Francisco, Ana Rita; Menezes, Miguel; Lima da Silva, G.; Gonçalves, Inês; Rigueira, Joana; Carrilho-Ferreira, Pedro; Jorge, C.Background: Functional coronary lesion assessment by fractional flow reserve (FFR) is commonly employed worldwide. Recently, several studies have focused on a new parameter, the instantaneous wave free ratio (iFR), as an alternative or complementary method to FFR which does not require the use of adenosine. The use of iFR, however, is not consensual: its ideal cut-off and interpretation are still not completely...
