Background: Aortic valve disease has become one of the important factors affecting human health. Aortic valve disease is a progressive disease, if not actively treated, the prognosis is poor. Aortic valve replacement (AVR) surgery is an important treatment for aortic valve disease. At present, the AVR surgery using biological valve accounts for abo...

Background The objectives of the present study were (1) to evaluate the echocardiographic prognostic factors associated with improved left ventricular (LV) systolic function after aortic valve replacement, and (2) to compare the long-term outcomes after aortic valve replacement in chronic aortic regurgitation (AR) patients with or without LV dysfun...

Cryptococcal endocarditis has rarely been reported. Most patients with this condition are associated with risk factors, such as structural heart disease/valve replacement, immunodeficiency/immunosuppression or drug abuse. We report a case of cryptococcal endocarditis of the native valves without any risk factors. A 50-year-old Chinese man was admit...

The patient with severe asymptomatic aortic stenosis presenting for elective noncardiac surgery poses a unique challenge. These patients are not traditionally offered surgical aortic valve replacement or transcatheter aortic valve replacement given their lack of symptoms; however, they are at increased risk for postsurgical complications given the ...

Aortic valve replacement for aortic stenosis represents one of the most frequent surgical procedures on heart valves. These patients often have concomitant mitral regurgitation. To reveal whether the moderate mitral regurgitation will improve after aortic valve replacement alone, we performed a systematic review and meta-analysis. We identified 27 ...

The safety and efficacy of aortic root enlargement (ARE) at the time of aortic valve replacement (AVR) remains unknown. The objective of this multicenter study was to compare AVR with ARE to AVR for early and late mortality and secondary safety outcomes. Clinical and administrative databases in Ontario, Canada, were linked to obtain patients underg...

The Carpentier-Edwards Perimount valves have a proven track record in aortic valve replacement: good durability, hemodynamic performance, rates of survival, and low rates of valve-related complications and prosthesis-patient mismatch. The St. Jude Medical Trifecta is a newer valve that has shown comparable early and midterm outcomes. Studies show r...

Retention of the native aortic valve when performing aortic root surgery for aneurysmal disease has become a more common priority. We reviewed our experience in valve-sparing aortic root replacement (VSARR) to evaluate the long-term outcomes and the risk factors for reoperation. From January 1994 through June 2017, 342 patients (mean age 47.8 ± 15....

We present a novel approach to simulate deformation in aortic valve replacement scenarios with applications in operation planning and batch domain creation for large computational fluid dynamics studies of the aortic arch.
