1. Oral Use of Phenytoin to Reduce Calcification in Bovine Pericardium and Porcine Aortic Leaflets Implants in Rats
Abstract Introduction: This study aims to test the effect of phenytoin as an inhibitor of the process of dystrophic calcification in bovine pericardium and porcine leaflets implanted in the subcutaneous tissue of rats. Methods: Isolated segments of biomaterials were implanted subcutaneously in young rats. The study groups received 500 mg phenytoin per kilo

2. The Anaortic Technique with Bilateral Internal Thoracic Artery Grafting - Filling the Gap in Coronary Artery Bypass Surgery
Abstract Coronary artery bypass grafting (CABG) has consolidated its role as the most effective procedure for treating patients with advanced atherosclerotic coronary artery disease, reducing the long-term risk of myocardial infarction and death compared to other therapies and relieving angina. Despite the recognized benefits afforded by surgical myocardial

3. The rs10455872-G allele of the LPA gene is associated with high lipoprotein(a) levels and increased aortic valve calcium in a Mexican adult population
Abstract Polymorphisms in the LPA gene have been associated with aortic valve calcification (AVC). There are wide differences in the allelic frequencies, Lp(a) levels, and the association with AVC among ethnic groups. The aim of this study was to determine the association of the LPA gene polymorphisms with Lp(a) levels and risk of developing AVC, in Mexican-

4. Aortic Arch Calcification on Routine Chest Radiography is Strongly and Independently Associated with Non-Dipper Blood Pressure Pattern
Resumo Fundamento: A pressão arterial não-dipper é uma das causas mais importantes de lesão de órgão-alvo da hipertensão e de eventos cardiovasculares futuros. Atualmente, não há uma ferramenta prática para prever o padrão não-dipper de pressão arterial. Objetivos: O objetivo deste estudo foi investigar a relação entre a calcificação no ar

5. Totally Percutaneous Access Using Perclose Proglide for Endovascular Treatment of Aortic Diseases
Abstract Objective: To evaluate our experience following the introduction of a percutaneous program for endovascular treatment of aortic diseases using Perclose Proglide® assessing efficacy, complications and identification of potential risk factors that could predict failure or major access site complications. Methods: A retrospective cohort study during

6. Lipoic acid, but not tempol, preserves vascular compliance and decreases medial calcification in a model of elastocalcinosis
Vascular calcification decreases compliance and increases morbidity. Mechanisms of this process are unclear. The role of oxidative stress and effects of antioxidants have been poorly explored. We investigated effects of the antioxidants lipoic acid (LA) and tempol in a model of atherosclerosis associated with elastocalcinosis. Male New Zealand white rabbits

7. Relação entre doenças periodontais e aterosclerose subclínica em indivíduos com hipercolesterolemia familiar / Association between periodontitis and subclinical atherosclerosis in familial hypercholesterolemia individuals
Introduction: Periodontitis is an inflammatory disease with consequent destruction of teeth supporting tissues. It has multifactorial etiology, and its main cause is accumulation of periodontal pathogens on the dental surface. Periodontitis has been associated with the advance of atherosclerosis. Familial hypercholesterolemia patients display premature devel

8. Fatores de risco para acidente vascular cerebral no pós-operatório de cirurgia de revascularização do miocárdio
Introdução: A indicação de endarterectomia carotídea (EAC) profilática em conjunto com revascularização miocárdica (CRM) permanece assunto indefinido. A cirurgia conjunta é amplamente difundida, mas seus resultados vêm sendo questionados. Método: Coorte retrospectiva de 691 pacientes submetidos à CRM, escolhidos aleatoriamente. Avaliação reali

9. Idiopathic aortitis with calcification of ascending aorta, and aortic and mitral valves.
A young woman with unexplained radiographic calcification of the ascending aorta was found at necropsy to have healed idiopathic aorititis. Calcification also involved the aortic valve which was stenosed and the mitral valve. Death was the result of infective endocarditis of these valves with aortic ring abscess, rupture of aortic root, and cardiac tamponade

10. Comparison of cinefluoroscopy and M mode echocardiography for detecting aortic valve calcification. Correlation with severity of stenosis of non-rheumatic aetiology.
The density of aortic valve calcification was estimated using cinefluoroscopy and M mode echocardiography in 86 patients with pure aortic stenosis. The results were compared with the degree of outflow obstruction measured haemodynamically. Cinefluoroscopic estimates of aortic valve calcification correlated well with the measured aortic valve gradient whereas

11. Long-term degenerative changes in aortic segment homografts, with particular reference to calcification
The object of this article is to present observations derived from a long-term follow-up (over a period of 8-17 years) of a personal series of aortic segment homografts from which certain important information arises. It will be shown that in those grafts prepared and preserved in a `fresh' state, calcification has not occurred or has been trivial, whereas i
