What is Paravalvular abscess?
Methods: Paravalvular abscess was defined as infective necrosis of the valve annulus that required patch reconstruction before implanting a new valve.
What causes aortic root abscess?
Epidemiology. Aortic root abscess occurs as a complication of infective endocarditis in 10-37% 9. Abscess formation in post-surgical patients (aortic root repair and/or aortic valve replacement) is most commonly encountered in the first 5 years following surgery, most of which occur in the first 2 years.
What is an aortic abscess?
Aortic root abscess (ARA) is a catastrophic complication of aortic root endocarditis, involving both native and prosthetic valves, which often warrants surgical intervention. Currently, aortic valve replacement (AVR) and aortic root replacement (ARR) are the most widely employed techniques.
What is myocardial abscess?
A myocardial abscess is a life-threatening disorder of the endocardium, and early recognition and initiation of treatment are necessary for patient survival. In the majority of cases, a myocardial abscess is a complication of endocarditis that either involves native or prosthetic valves.
What causes heart abscess?
Excerpt. A cardiac abscess is a suppurative infection of the myocardium, endocardium, native or prosthetic valve tissue. Similar to other abscesses, it develops either by dissemination from a distant source such as bacteremia or sepsis or by direct extension of a pre-existing cardiac infective focus.
What is an annular abscess?
Annular abscesses (AA) are serious complications of. infectious valvular endocarditis. It is well known that aortic valve endocarditis is much more frequently complicated by ring abscesses than mitral or tricuspid endocarditis [1, 2].
How long can u live with endocarditis?
Conclusions: Long term survival following infective endocarditis is 50% after 10 years and is predicted by early surgical treatment, age < 55 years, lack of congestive heart failure, and the initial presence of more symptoms of endocarditis.
What are the risks of surgery for paravalvular abscess?
Conclusions: Surgery for active endocarditis with paravalvular abscess was associated with high operative mortality, particularly in patients in shock and abscess of both mitral and aortic annuluses. Long-term survival was adversely affected by age and recurrent bouts of endocarditis.
What kind of abscess is the aortic valve?
Aortic root abscess, a severe form of infective endocarditis (IE) of the aortic valve and adjacent tissues, continues to challenge cardiovascular surgeons.
What is the mortality rate for aortic root abscess?
The operative mortality rate for the surgical treatment of aortic root abscess varies from 3.9% to 25%. Early intervention for IE with extended sequelae is known to have better outcomes and for this reason leads surgeons to early operation if life-threatening sequelae do not develop.
When to use a pericardial patch for aortic root abscess?
When a circular abscess was larger than one aortic cusp without aortoventricular dehiscence, the defect on the aortic anulus was reconstructed with use of a pericardial patch, and pledgeted sutures were placed on this patch during AVR (n=11; 40.8%).
