Microemboli in aortic valve replacement
Expert Review of Cardiovascular Therapy, 2006Microembolic signals (MES) can be detected in many recipients of mechanical aortic valve prostheses by transcranial Doppler ultrasound. The nature and etiology of these MES have remained unclear for a long time. The solid and gaseous nature of MES are discussed, as well as whether or not MES may reflect artifacts.

HETEROGRAFT AORTIC VALVE REPLACEMENT
Medical Journal of Australia, 1968Heterograft aortic valves from calves and pigs were used as valve replacements in 23 patients at St. Vincent's Hospital, Melbourne, from February, 1966, to November, 1966. The results point to some advantages in this method of valve replacement, but long-term follow-up of function must be carried out before it can be applied to patients with less ...

Aortic Valve Replacement in Octogenarians
Heart, Lung and Circulation, 2014With improved life expectancy more octogenarians now present with aortic valve disease. Cardiac surgery in this group of patients has previously been considered high risk due to co-morbidities and challenges of rehabilitation. This study seeks to challenge the concept of octogenarian cardiac surgery "unsuitability" by analysing operative outcomes and ...

Aortic valve replacement is a procedure unique in its ability to resolve significant and worsening aortic valve disease of any aetiology. The valve substitute can be a mechanical valve (usually a bileaflet valve), bioprosthesis (stented, stentless, sutureless, or transcathetral), allograft, or autograft.

Emergency aortic valve replacement
The American Journal of Surgery, 1976The aortic valve was replaced as an emergency in twenty-seven patients between July 1970 and December 1974. Twenty-two patients had critical aortic stenosis and five had acute aortic insufficiency. The indications for emergency surgery were cardiac arrest in five patients, low cardiac output in four patients, and medically intractable pulmonary edema ...

HETEROGRAFT AORTIC-VALVE REPLACEMENT
The Lancet, 1967Abstract Heterograft aortic valves from calves and pigs were used as valve replacements in 23 patients at St. Vincent's Hospital, Melbourne, from February, 1966, to November, 1966. The results point to some advantages in this method of valve replacement, but long-term follow-up of function must be carried out before it can be applied to patients with ...

Aortic Valve Replacement in the Young
Journal of Cardiac Surgery, 1994The attractiveness of the aortic allograft in any form, whether it be free style or root, is the high 10-year freedom from thromboembolism, absence of requirement for anticoagulants, use in active infections, excellent hemodynamics, and freedom from reoperation. The 10-year freedom from all valve related complications has been reported to be around 92%

Transcatheter aortic valve replacement
2017After more than ten years of development, A. Cribier accomplished in 2002 the first percutaneous aortic valve replacement (AVR), which is a curative procedure for severe aortic stenosis and an alternative to surgery for high risk patients. With material improvements over time, the procedure has evolved to become a purely percutaneous intervention in ...

Transcatheter Aortic Valve Replacement
Anesthesiology Clinics, 2008Aortic stenosis is one of the most common valve pathologies found in adults. Aortic valve replacement via a sternotomy and cardiopulmonary bypass is the treatment of choice for patients with symptomatic aortic stenosis with very acceptable risk. However, patients with advanced age and multiple comorbidities carry significant operative risk; operative ...

Percutaneous aortic valve replacement
Current Cardiology Reports, 2008Aortic 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 ...
