HETEROGRAFT AORTIC VALVE REPLACEMENT

Medical Journal of Australia, 1968
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 less ...

Aortic Valve Replacement

2018
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.

Aortic Valve Replacement in the Young

Journal of Cardiac Surgery, 1994
The 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

Anesthesiology Clinics, 2008
Aortic 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 ...

Transcatheter aortic valve replacement

2017
After 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 ...

HETEROGRAFT AORTIC-VALVE REPLACEMENT

The Lancet, 1967
Abstract 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 ...

Emergency aortic valve replacement

The American Journal of Surgery, 1976
The 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 ...

Transcatheter Aortic Valve Replacement

Anesthesiology Clinics, 2013
The percutaneous transcatheter aortic valve replacement (TAVR) procedure, introduced in 2002, has emerged as a successful and comparable treatment option for many patients with aortic stenosis. Balanced general anesthesia or monitored anesthesia care in addition to local anesthesia have been used during transfemoral and transapical approaches.

Percutaneous aortic valve replacement

Current Cardiology Reports, 2008
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 ...

Transcatheter Aortic Valve Therapy Is Not Aortic Valve Replacement [PDF]

The Annals of Thoracic Surgery, 2009
I read with interest the increasing number of scientific articles involving transcatheter aortic valve replacement. The meaning of the term “replacement” is to substitute something with something else. Yet, at present, the only way to substitute a stenotic aortic valve is to take away the calcific or fibrotic tissue and put in a new prosthetic valve,
