INTRODUCTION AND OBJECTIVES Percutaneous aortic valve implantation for patients with severe symptomatic aortic stenosis and a high surgical risk is currently well established. We report our experience in terms of safety and effectiveness of transcatheter aortic valve implantation in other clinical context like the degenerated aortic homografts. METHODS We report our initial experience in four...

Results PAVR was performed in 137 consecutive patients. All but 1 patient underwent planned arteriotomy closure using a percutaneous pre-closure technique. Smaller sheaths, rigorous angiographic and computed tomographic screening and patient selection, and percutaneous vascular repair techniques were increasingly used over this period. From 2009 to 2010, major vascular complications decreased f...

Background EuroSCORE has been proposed to identify patients at high risk for surgical aortic valve replacement and estimate for them the risk-benefit of percutaneous implantation. However, it has been clearly demonstrated that this system overestimates mortality, particularly in the elderly population undergoing surgery for aortic valve replacement. An actualized model called EuroSCORE II has b...

Aortic valve replacement can produce dramatic benefit in the setting of aortic stenosis. The potential for morbidity and mortality associated with thoracotomy, cardiopulmonary bypass, and aortotomy has fostered a search for alternatives. Early experience with transcatheter endovascular aortic valve implantation demonstrated feasibility and durability, but the procedure was difficult to reproduc...

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...

CASE A 26-year-old woman who had congenital aortic valve stenosis presented with exertional dyspnea. She had undergone percutaneous balloon aortic valvuloplasty 12 years previously at the age of 14. When she was 20 years old, she delivered a neonate by elective cesarean section at the 31st week of gestation because the mean pressure between the left ventricle and the ascending aorta was 52 mmHg...

Surgical aortic valve replacement (AVR) is the standard of care for patients with symptomatic severe aortic stenosis (AS), providing relief of symptoms and prolonging survival. However, many patients are either denied or not offered surgery due to high surgical risk or non-operability for open AVR. The technology of percutaneous aortic valve implantation emerged in 2002, and has since evolved r...

  Introduction: Aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. Recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. The purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients ho...

Reintervention of a mitral degenerated bioprosthesis has high surgical risk, especially in elderly patients with multiple comorbidities. We report 74 years old female two previous cardiac procedures and new structural deterioration severe regurgitation. Considering her high-surgical fully percutaneous treatment was performed balloon-expandable aortic valve position (valve-in-valve) through tran...

BACKGROUND Percutaneous aortic valve replacement is a new emerging technology for interventional treatment of severe aortic valve stenosis in surgical high-risk patients. This study was intended to provide a summary of the development and current safety and efficacy status of the self-expanding CoreValve Revalving prosthesis. METHOD AND RESULTS Between 2005 and 2008, we have enrolled 136 cons...
