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 the Elderly
Journal of the American Geriatrics Society, 1983In order to determine the risk of aortic valve replacement in the elderly, 77 patients over the age of 60 who had undergone this procedure were reviewed. Hypothermic‐hyperkalemic cardioplegia was used in all patients. In 55 patients with isolated aortic valve replacement there were three deaths (5.5 per cent).

Transcatheter Aortic Valve Therapy Is Not Aortic Valve Replacement
The Annals of Thoracic Surgery, 2009I 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,

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 ...

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 ...

Transcatheter Aortic Valve Replacement
Dimensions of Critical Care Nursing, 2012Symptomatic severe aortic stenosis is a serious life-threatening condition that requires surgical intervention. Until recently, the only available treatment options were through an open-heart surgery technique. A transcatheter aortic valve replacement is a minimally invasive aortic valve replacement procedure that is available for symptomatic patients ...

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.
