A comparison of the diagnostic capabilities of the ratio of acceleration time to total left ventricular ejection time (AT/ET) in determining the severity of aortic stenosis in patients with bicuspid and tricuspid aortic valve: retrospective comparative study [PDF]

КардиоСоматика, 2023
Objective. We aimed to compare the diagnostic capabilities of the ratio of acceleration time to total left ventricular ejection time (AT/ET) in determining the severity of aortic stenosis (AS) in patients with bicuspid and tricuspid aortic valves (AV).

Age, Sex, and Valve Phenotype Differences in Fibro‐Calcific Remodeling of Calcified Aortic Valve

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background In calcific aortic valve disease on tricuspid aortic valves (TAVs), men have higher aortic valve calcification and less fibrosis than women. However, little is known in bicuspid aortic valves (BAV).

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

Abnormal wave reflections and left ventricular hypertrophy late after coarctation of the aorta repair [PDF]

, 2017
Patients with repaired coarctation of the aorta are thought to have increased afterload due to abnormalities in vessel structure and function. We have developed a novel cardiovascular magnetic resonance protocol that allows assessment of central ...

Space closure and incisor alignment in the mandibular arch following first premolar extraction without appliance therapy

Australasian Orthodontic Journal, 1989
Changes in the mandibular arch were evaluated in 32 cases of lower first premolar extraction without appliance therapy. There was a mean reduction in the irregularity index and extraction space of 52 percent and 45 percent respectively.
