1. Evaluation of Polymorphisms in IL8 and IL16 Genes in Patients with Acute Coronary Syndrome
Abstract Background: Acute coronary syndrome (ACS) is a cardiovascular disease caused by obstruction of coronary arteries by atheromatous plaque. Susceptibility to this disease may be related to genetic variations, such as single nucleotide polymorphisms (SNPs). Objective: In this study, we evaluated the relationship between SNPs in IL8 (rs4073; -251 A/T)

2. Hemodynamic and Imaging Assessment of Transcatheter Aortic Valve Replacement with the Inovare® Proseal using Multislice Computed Tomography
Abstract Objective: To evaluate the hemodynamic performance (i.e., gradients and paravalvular leakage [PVL]) of the new and experimental Braile Inovare® Proseal. Additionally, we aimed to assess pre and postoperatively the aortic annulus and the transcatheter prosthesis using multislice computed tomography (MSCT). Methods: Patients were selected by a mult

3. Emergent Percutaneous Rotational Atherectomy to Bailout Surgical Transapical Aortic Valve Implantation: A Successful Case of Heart Team Turnaround
Resumo O implante valvar aórtico transcateter (TAVI) é um tratamento estabelecido para estenose aórtica grave (EA) em pacientes com risco cirúrgico elevado. Doença arterial coronariana concomitante afeta 55-70% dos pacientes com EA grave. A intervenção coronária percutânea em pacientes com TAVI pode ser um desafio. Relatamos um caso de obstrução c

4. Spontaneous Exercise-Related Coronary Artery Dissection among Young Patients Without Risk Factors or Atherosclerotic Disease
Resumo A dissecção espontânea da artéria coronária (DEAC) é considerada uma síndrome coronariana aguda frequentemente subdiagnosticada e com poucos casos descritos na literatura. A sua associação ao exercício físico em pacientes jovens e sem fatores de risco ou doença aterosclerótica coronariana (DAC) é ainda mais rara. Por esse motivo, foi rea

5. Coronary Involvement in Behçet's Disease: what are its Risks and Prognosis? (Rare Cases and Literature Review)
Abstract Objective: In our clinic, we aimed to investigate the effect of preoperative risk factors and postoperative complications on reoperation and mortality in cases with Behçet's disease which presents very rare coronary artery involvement. Methods: Thirteen patients with Behçet's Disease who had undergone coronary artery bypass grafting in our cen

6. Impact of Periodontal Disease on Late Morbimortality (10 Years) of Pacientes with Acute Coronary Syndrome
Abstract Background: It is known that predisposing factors for periodontal disease (PD) and cardiovascular diseases are similar, just as dissemination of oral flora pathogens can induce the development of cardiovascular diseases, which play a direct role on the morbimortality of patients. Objective: To assess the impact of periodontal disease in the presen

8. Circulating levels of adiponectin and extent of coronary artery disease in patients undergoing elective coronary angiography
Adiponectin (APN), an adipose tissue-released adipokine with demonstrated anti-inflammatory and anti-atherogenic properties, is encoded by a gene whose polymorphisms are associated with presence of coronary artery disease (CAD). Serum APN levels are inversely related with presence and complexity of CAD. Within this context, we sought to compare levels of tot

9. Obstrucao Coronaria apos Implante por Cateter de Protese Valvar Aortica
Fundamentos: O implante por cateter de bioprótese valvar aórtica (TAVI) consolidou-se como alternativa para o tratamento de pacientes com estenose aórtica importante de alto risco cirúrgico. Contudo, há poucos dados na literatura com respeito à obstrução coronária que, apesar de rara, trata-se de grave complicação do TAVI. Objetivo: Avaliar,

10. Avaliação tardia dos stents liberadores de Biolimus A9® pela tomografia de coerência óptica: análise da cobertura tecidual e da aposição das hastes / Long-term follow-up Biolimus A9TM stents with optical coherence tomography: strut apposition and tissue coverage analysis
Introduction: First generation drug-eluting stents (DES) have emerged as a strategy to prevent in-stent restenosis and the need of target-vessel revascularization when compared to bare metal stents (BMS); but at the expense of a higher risk of very late stent thrombosis (ST). Uncovered and malapposed struts may be associated with both late and very late ST.

11. Análise do grau de lesão obstrutiva coronária e sua correspondente parede miocárdica como fatores preditivos de perviedade e remodelamento da artéria radial na revascularização do miocárdio / Analysis of coronary obstruction and irrigated myocardial wall as predictive factors for patency and remodeling of radial artery grafts in coronary artery bypass surgery
A artéria radial (AR) constitui valiosa opção de enxerto na revascularização do miocárdio (RM), desde a retomada de seu uso, nos anos 1990. O objetivo deste estudo foi avaliar perviedade e remodelamento dos enxertos de AR e sua relação com lesão obstrutiva pré-operatória e parede miocárdica revascularizada, observando-se também os enxertos de ar

12. Frequencia de aterosclerose nas arterias radiais de 29 cadaveres / Frequency of atherosclerosis in radial arteries of 29 cadavers
The use of radial artery as a coronary artery bypass graft increased since 1992. It is justified that arterial grafts theoretically would last more than venous grafts. But radial arteries could have atherosclerotic obstructions before cardiac bypass grafting surgery. The objective of this study is to verify the incidence of atherosclerotic obstructions and m
