The modified Cox maze procedure and surgical pulmonary vein isolation were similarly effective in restoring sinus or regular rhythm in permanent atrial fibrillation associated with mitral valve disease. These results favor the adoption of surgical isolation as a preferable technique, simpler and equally effective in controlling atrial fibrillation. The results also can bring further information for understanding the mechanisms involved in origins and treatment of chronic permanent atrial fibrillation.
Fatores de risco para mortalidade hospitalar no implante de prótese valvar mecânicaRisk factors for hospital mortality in valve replacement with mechanical prosthesis Rev Bras Cir Cardiovasc 2009; 24(3): 334-340 requiring long time of anticoagulation and for those who wishes to minimize the need for reoperation. The aim of this prospective study, with retrospective data acquisition, is to review the number of patients who underwent implantation of mechanical heart valve prosthesis, St Jude Medical model, in order to identify risk factors that can influence hospital mortality.
METHODS
Study CharacteristicsProspective study with retrospective data acquisition.
PopulationThe study included 335 patients who underwent at least one mechanical prosthesis of St. Jude Medical model, from December 1994 to September 2005, at Institute of Cardiology of Rio Grande do Sul/University Foundation of Cardiology. Of these, 181 (54%) were male and 154 (46%) were females, aged between 16 and 78 years, mean 46.8 ±
Objective: To evaluate the safety, feasibility and initial and clinical effects on myocardial perfusion, intramyocardial, transthoracic administration of plasmid VEGF 165 in patients with advanced coronary artery disease and refractory angina, which are not qualified for percutaneous revascularization and surgery.Methods: A cohort study phase I. Thirteen patients with ischemic heart disease refractory angina despite maximum medical treatment for at least six months, not qualifying for surgical or catheter underwent intramyocardial injection of VEGF 165 plasmid 2000ìg. Patients were evaluated by myocardial scintigraphy, exercise testing, quality of life questionnaire (Minnesota) and determining the classes of heart failure (NYHA) and angina (CCS).Results: There were no deaths or recurrences. During the period of maximum medical treatment, there was no difference in myocardial scintigraphy, exercise stress tests and questionnaires on quality of life also found a trend towards worsening of NYHA class (P = 0.05) and CCS (P = 0.05) . Three months after intervention we observed improvements in scintigraphic SSS scores (18.38 ± 7.51 vs. 15.31 ± 7.29, P = 0.003) and SRS (11.92 ± 7.49 vs. 8.53 ± 6.68, P = 0.002) but not in proportion to the areal extent of ischemic Rev Bras Cir Cardiovasc 2010; 25(3): 311-321 of administration of VEGF. Clinical trials bring controversial results, many showing evidence of clinical improvement and angiogenesis [8][9][10][11][12][13][14][15][16][17][18][19] and others showing no differences in myocardial perfusion when compared to their controls [7,20]. Thus, although promising, remain still not completely clear the clinical effects on the myocardium vascularization of the therapy with VEGF in its various forms and ways of administration, justifying further studies.
KALIL, RAK ET AL -VEGF gene therapy for angiogenesis in refractory angina: clinical trial phase I/IIThis clinical assay aims to evaluate the safety, feasibility and initial clinical effects (featuring a clinical assay phase I / II), under myocardial perfusion, intramyocardial, transthoracic administration of plasmid VEGF 165 in patients with advanced CAD and refractory angina, which are not qualified for surgery and percutaneous revascularization. We emphasize that we used for the first time, a plasmid entirely produced in Brazil.
Intramyocardial transplantation of BMMC in dilated cardiomyopathy cases is feasible and safe. There were early improvements in symptoms and LV performance. Medium-term evaluation revealed regression of LV function, although maintaining improved functional class.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
