Vitamin K2 and D in Patients With Aortic Valve Calcification: A ...
2022年4月25日 · Menaquinone-7 (MK-7), also known as vitamin K2, is a cofactor for the carboxylation of proteins involved in the inhibition of arterial calcification and has been suggested to reduce the progression rate of aortic valve calcification (AVC) in patients with aortic stenosis.
Aortic valve decalcification - The Journal of Thoracic and ...
Adequate decalcification with restoration of leaflet mobility was achieved in all patients, including seven with bicuspid aortic valves. Leaflet perforation occurred and was successfully repaired in five patients.
Aortic valve decalcification - PubMed
Ultrasonic decalcification is effective in relieving aortic stenosis, but subsequent restenosis and insufficiency may limit its application. Ultrasonic decalcification of the aortic valve was performed in 22 elderly patients with critical aortic stenosis (aortic valve areas less than 0.8 cm2) as an alternative to prosthetic valve replacement.
From 1978 through 1984, decalcification of the aortic valve was performed in 8 patients who were undergoing coronary artery revascularization. Preoperative gradients of be- tween 30 and 80 mm Hg (mean, 50 mm Hg) were abolished after operation.
Ultrasonic decalcification of the aortic valve was perfonned in 22 elderly patients with critical aortic stenosis (aortic valve areas < 0.8 cm2) as an alternative to prosthetic valve replacement. AU of the patients had symptoms. The mean New York Heart Association class was 3.3 ± 0.9.
Why and How to Measure Aortic Valve Calcification in Patients …
Aortic valve calcification as measured by CT is an accurate, reproducible, and well-validated marker of stenosis severity, progression of disease, and a powerful predictor of adverse events. Measurement of CT-AVC requires a gated, noncontrast CT scan and some training in correctly identifying the aortic valve calcification on axial CT slices.
Decalcification of the aortic valve does not prevent early ...
Aortic valve decalcification can effectively remove calcifications, but leaves a fibrillar structure that tends rapidly to accumulate calcium. Even normal-appearing tissue from diseased valves has a higher potential for calcification than normal valvular tissue. These data support the observation of …
A new ultrasonic process for a renewal of aortic valve decalcification ...
2006年1月5日 · Aortic valve decalcification by ultrasound was given up. We evaluated a new ultrasound microhandpiece (Dissectron Penstyle®) to rehabilitate this alternative treatment. We used under magnifying lenses the ultrasound microhandpiece to decalcify 30 …
Mechanical Decalcification of the Aortic Valve - ScienceDirect
1986年9月1日 · From 1978 through 1984, decalcification of the aortic valve was performed in 8 patients who were undergoing coronary artery revascularization. Preoperative gradients of between 30 and 80 mm Hg (mean, 50 mm Hg) were abolished after operation.
Aortic valve decalcification - ScienceDirect
1990年7月1日 · We concentrated our efforts of decalcification on degenerative or senile aortic stenosis and excluded bicuspid and rheumatic aortic valve disease, because of previously published data from our own institution and other series of mechanical debridement.
