The Annals of Thoracic Surgery, 1978
Despite continued refinement of heart valve prostheses, valve replacement carries risks of thromboembolic, mechanical, and infectious complications, and long-term success is further limited by the eventual wear of prosthetic parts. In many patients with congenital or acquired valve diseases, valve function may be improved, if not restored, by ...

Current Opinion in Cardiology, 1993
Progress in valve repair and replacement continued over the past year. Aortic valve repair for aortic insufficiency appears promising, and aortic decalcification may still be a useful alternative in certain cases of aortic stenosis. Mitral valve repair, well accepted for myxomatous valves, presents a challenge in ischemic disease.

Minimally Invasive Valve Surgery
Seminars in Thoracic and Cardiovascular Surgery, 2007As alternatives to standard sternotomy, surgeons have developed innovative, minimally invasive approaches to conducting valve surgery. Through very small skin incisions and partial upper sternal division for aortic valve surgery and right minithoracotomy for mitral surgery, surgeons have become adept at performing complex valve procedures.

Minimally invasive valve surgery
Current Opinion in Cardiology, 1998Minimally invasive surgical techniques have proliferated at a staggering rate in the last decade. Cardiac surgery has been a late entrant in this process but is currently experiencing a surge of interest in and techniques for minimally invasive approaches.

Facial Plastic Surgery, 2011
Nasal obstruction can be due to internal and external valve problems that can be seen before and after rhinoplasty. The main scope of this article is to concentrate on surgical solutions to these problems. To overcome nasal obstruction at the internal valve, spreader grafts, spreader flaps, upper lateral splay graft, butterfly graft, flaring suture, M ...

Seminars in Thoracic and Cardiovascular Surgery, 2003
A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have ...

Minimally Invasive Valve Surgery
Journal of Cardiac Surgery, 2001Cardiac surgery has been the last area of clinical surgery to adopt and embrace minimally invasive surgical techniques. Since the onset of arterial embolectomy in 1965, arthroscopic knee surgery performed in 1975 and laparoscopic cholecystectomy in 1985, huge advances in videoscopic, thorascopic and small incision surgery has taken place in all ...

Patents and Heart Valve Surgery - I: Mechanical Valves
Recent Patents on Cardiovascular Drug Discovery, 2013Valvular heart disease, inherited or acquired, affects more than 5 million Americans yearly. Whereas medical treatment is beneficial in the initial stages of valvular heart disease, surgical correction provides symptomatic relief and long-term survival benefits.

Surgery (Oxford), 2004
Abstract Heart valve surgery constitutes 30% of all adult cardiac surgery procedures. The most frequent valvular abnormality requiring surgery is acquired aortic stenosis. The aetiology of aortic stenosis varies considerably with age. Isolated congenital aortic stenosis presenting below 2 years of age can be often treated with open valvotomy.
