The prevalence of aortic valve stenosis (AS) is growing in developed countries because its prevalence increases with age. A growing number of elderly patients are currently referred to specialized centres to be evaluated for potential therapeutic strategies. Indeed, two techniques are nowadays able to treat high-risk AS patients: TAVI and surgical replacement (AVR). It is the purpose of the present review to summarize current knowledge on safety and efficacy of AVR and TAVI in high-risk patients; to focus on some aspects of recently published guidelines; to emphasize the growing importance of pre-operative individual risk assessment, which is considered the real crucial point for patient selection and trial's comparisons...

Surgeons are now facing the challenge of redo valve surgery because of the increasing number of elderly individuals in Japan. The incidence of bioprosthesis dysfunction has increased among the various surgical indications of redo valve surgery due to the preference of patients and a paradigm shift in prostheses from mechanical valves to bioprostheses. Previous studies reported that the clinical outcomes of reoperative valvular surgery have markedly improved due to the maneuver of myocardial protection, cardiopulmonary bypass strategies, and appropriate safer surgical approach...

BACKGROUND: Valvar heart disease is an important public health problem, more common in developing countries, especially in younger. OBJECTIVE: To evaluate the epidemiological features of patients and its influence on the prosthesis type choice used on patients who underwent valve surgery. METHODS: Cross-sectional. Data such as age, sex, provenance, surgery procedure and prosthesis type were retrospectively analyzed. We reviewed 366 charts of all patients submitted to heart valve surgery during three years in a public health cardiovascular treatment center...

BACKGROUND: The working group "Aortic Surgery and Interventional Vascular Surgery" of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) set up the German registry for acute aortic dissection type A (GERAADA) in July 2006. This web-based database was developed to record data of patients who had undergone surgery for aortic dissection type A (AADA). The aim of GERAADA is to learn from analyzing the data of AADA patients how to improve the perioperative management and surgical treatment of patients with AADA and to identify possible parameters affecting patient risk and outcome...

During the past few decades, percutaneous valvular procedures have been used in mitral and aortic stenosis. Percutaneous mitral commissurotomy, which has virtually replaced surgical commissurotomy in the treatment of mitral stenosis, has been performed since the mid-1980s and has provided good results in thousands of patients worldwide. Percutaneous balloon aortic valvuloplasty has largely been abandoned due to its limited efficacy and the risks involved. New percutaneous procedures are currently being developed in mitral regurgitation and aortic stenosis, which represent the two most frequent valve diseases in industrialized countries...

Calcific aortic valve disease (CAVD) is the most common acquired valvular disorder in developed countries. CAVD ranges from mild thickening of the valve, known as aortic valve sclerosis (AVSc), to severe impairment of the valve motion, which is termed aortic valve stenosis (AVS). The prevalence of CAVD is nearing epidemic status: its preceding stage, in which there is aortic sclerosis without obstruction of the left ventricular outflow, is present in almost 30% of adults aged over 65 years. As there is no existing medical therapy to treat or slow the progression of CAVD, surgery for advanced disease represents the only available treatment...

Rheumatic heart disease is the most serious sequelae of rheumatic fever occurring in approximately 30% of rheumatic fever patients. Patients with acute rheumatic fever may develop varying degrees of pancarditis with associated valve disease, heart failure, and pericarditis. Worldwide, rheumatic heart disease remains a major health problem although its prevalence in the developed countries is much reduced. Involvement of the mitral valve results in mitral regurgitation and/or stenosis. Where surgery is indicated, mitral valve replacement is usually necessary although in some cases, mitral valve repair is possible...

COMPARATIVE STUDY

BACKGROUND: Knowledge is limited on how surgical outcomes compare between different geographical and health organisation settings. OBJECTIVE: To compare demographic features, surgery rates and in-hospital outcomes for 14 major types of surgery in older patients between the state of Victoria in Australia and the United States. METHODS: We obtained US Medicare data and data from the Department of Human Services Victorian Admitted Episodes Database for patients older than 65 years who underwent one of six major cardiovascular procedures or eight major cancer resections in a 5-year period (1994-1999 and 1998- 2003, respectively)...

Infective endocarditis (IE) is one of the most severe complications of parenteral drug abuse. The incidence of IE in intravenous drug abusers (IVDAs) is 2% to 5% per year, being responsible for 5% to 10% of the overall death rate. The prevalence of HIV infection among IVDAs with IE ranges between 30% and 70% in developed countries and HIV-infection by itself increases the risk of IE in IVDAs. The incidence of IE in IVDAs is currently decreasing in some areas, probably due to changes in drug administration habits by addicts to avoid HIV transmission...
