reater advances in the use of percutaneous techniques for he treatment of coronary artery disease and cardiac nonoronary interventions have occurred during the last few ears. Among them, percutaneous techniques for the treatent of stenotic valvular lesions were developed, and their enefits were demonstrated in the treatment of most paients with pulmonary stenosis, rheumatic mitral stenosis, nd ...

Aortic Stenosis (AS) is present in approximately 2% of people and is most commonly caused by degenerative calcification of the aortic valve. Without aortic valve intervention, aortic stenosis is associated with substantial morbidity and mortality in patients, particularly in those presenting with angina, syncope, or heart failure. The current gold standard for treatment of Aortic Stenosis is su...

BACKGROUND Studies on stroke risk following cardiac procedures addressed only perioperative and long-term risk following limited higher-risk procedures, were poorly generalizable, and often failed to stratify by stroke type. We calculated stroke risk in the intermediate risk period following cardiac procedures compared with common noncardiac surgeries and medical admissions. METHODS AND RESUL...

bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. sinus of valsalva aneurysm is an uncommon complicatio...

BACKGROUND Aortic valve replacement with cardiopulmonary bypass is currently the treatment of choice for symptomatic aortic stenosis but carries a significant risk of morbidity and mortality, particularly in patients with comorbidities. Recently, percutaneous transfemoral aortic valve implantation has been proposed as a viable alternative in selected patients. We describe our experience with a ...

INTRODUCTION transcatheter aortic valve implantation (TAVI) is an emerging technique for the treatment of aortic stenosis. With the advent of percutaneous suture devices for the access point and prosthesis delivery systems of smaller diameter, TAVI has become a truly percutaneous procedure: percutaneous aortic valve replacement (PAVR). Thus, PAVR may be conducted without general anaesthesia (GA...

Valve replacement is the most common therapy for diseased aortic valves. Percutaneous approaches are becoming increasingly popular, due to reduced procedural complications and lower follow-up rates. Still there is a lack of efficient tools for valve quantification and preoperative simulation of replacement and repair procedures. Thus the success of the intervention relies to a large portion on ...

BACKGROUND Aortic stenosis is of concern in the elderly. Although aortic valve replacement provides good long-term survival with functional improvement, many elderly patients are still not referred for surgery because of their age. Percutaneous aortic valve implantation offers an alternative to open-heart surgery. Concerns about the management of aortic valve stenosis in the elderly will be rev...

BACKGROUND Percutaneous aortic valve replacement represents an endovascular alternative to conventional open heart surgery without the need for sternotomy, aortotomy, or cardiopulmonary bypass. METHODS AND RESULTS Transcatheter implantation of a balloon-expandable stent valve using a femoral arterial approach was attempted in 50 symptomatic patients with severe aortic stenosis in whom there w...

Recently, percutaneous aortic valve replacement has emerged as a therapeutic option for patients with severe symptomatic aortic stenosis and a high surgical risk. We report our initial experience in four patients with percutaneous implantation of a CoreValve aortic prosthesis to treat aortic bioprosthesis dysfunction involving aortic stenosis or regurgitation. In-hospital and medium-term outcom...
