Although a patient's age may be the only objective figure that can be used as a reference indicator in selecting the type of prosthesis in heart valve surgery, different clinical guidelines use differ...
To explore the age-associated survival-hazard functions associated with prosthesis type in aortic valve replacement (AVR) and mitral valve replacement (MVR)....
This cohort study compared the long-term outcomes associated with mechanical and biologic prostheses in AVR and MVR according to recipient's age using a nationwide administrative data from the Korean ...
AVR, MVR, or both AVR and MVR with mechanical or biologic prosthesis....
The primary end point was all-cause mortality after receiving prosthetic valves. The secondary end points were the valve-related events, including the incidence of reoperation, systemic thromboembolis...
Of the total of 24 347 patients (mean [SD] age, 62.5 [7.3] years; 11 947 [49.1%] men) included in this study, 11 993 received AVR, 8911 received MVR, and 3470 received both AVR and MVR simultaneously....
In this nationwide cohort study, the long-term survival benefit associated with mechanical prosthesis vs bioprosthesis persisted until age 65 years in AVR and age 70 years in MVR....
The novel anastomosis technique, "subannular endomyocardial implantation of valve prosthesis (SEIV)," focuses on excluding aortic annular tissue from suture line to avoid vascular inflammation in Behç...
Comparative data on the clinical outcomes of TTK Chitra mechanical heart valve prosthesis (CHVP), an indigenously developed low-cost tilting disc valve and commonly used bileaflet valve, the St. Jude ...
We conducted a retrospective follow-up study of consecutive patients undergoing mitral (MVR) and aortic valve replacement (AVR) with SJM or CHVP mechanical prostheses over a 6-year period at our insti...
Seven hundred and thirty-five patients who underwent isolated MVR (n = 510) or AVR (n = 225) were included in the study. Patients with CHVP were younger and belonged to a lower socioeconomic class. Th...
The indigenously developed, low-cost CHVP has comparable midterm clinical performance as SJM in aortic or mitral positions....
A 78-year-old male was admitted to our institute with increasing shortness of breath and decreased exercise tolerance. His increasing symptoms were not relieved with medical management. He had a compl...
Intraoperative extraction of this prosthesis proved technically challenging and a valve in valve successfully was implanted as a salvage procedure....
The procedure was successful, and the patient made a full recovery....
Open valve in valve implantation, despite technical difficulties, may be utilized as a salvage procedure....
Prosthesis-patient mismatch (PPM), first described in 1978, occurs when a prosthetic valve functions normally, but has an effective orifice area that is too small relative to the patient's body surfac...
The objective of this scoping review is to describe the postoperative outcomes and complications of patients with bicuspid aortic valve (BAV) treated with sutureless or rapid-deployment prosthesis....
The use of sutureless and rapid-deployment prostheses is generally avoided in patients with BAV due to anatomical concerns and the elevated risk of para-prosthetic leaks. Multiple studies have reporte...
A scoping review was conducted using a comprehensive search strategy in multiple databases (Medline, Embase, Cochrane Central Register of Controlled Clinical Trials) for relevant articles. All abstrac...
Of 1052 total citations, 44 underwent full text review and 13 (4 case reports, 6 retrospective analyses, and 3 prospective analyses) were included in the scoping review. Across all 13 studies, a total...
The use of sutureless and rapid deployment prostheses in patients with BAV showed comparable intraoperative and implantation success rates to patients without BAV. Postoperative complications from usi...
The aim of this study was to describe the procedural and early outcomes of patients with mechanical mitral valve prosthesis (MVP) undergoing transcatheter aortic valve replacement (TAVR) with a novel ...
TAVR in patients with prior MVP may have an increased risk of complications related to device positioning and interference between both prosthetic valves....
An observational study was conducted, including eight patients with severe symptomatic aortic stenosis and prior mechanical MVP who underwent TAVR with the novel device Allegra...
The mean age of the study population was 75 years. The mean distance between MVP and aortic annulus was 3.8 mm. Procedural success was achieved in all patients with no major intraprocedural, in-hospit...
TAVR with Allegra TAVI system in patients with prior MVP offers good procedural and clinical outcomes....
This work presents a structural computational simulation of a polymeric aortic valve prosthesis, made with a hyperelastic material (Styrene-Ethylene/Propylene-Styrene). The valve has a suture ring, th...
The development of a novel artificial heart valve with outstanding durability and safety has remained a challenge since the first mechanical heart valve entered the market 65 years ago. Recent progres...
We aimed to summarise the existing knowledge regarding antithrombotic medications following surgical aortic valve replacement (SAVR) using a biological valve prosthesis....
We performed a meta-analysis of studies that reported the results of using antithrombotic medication to prevent thromboembolic events after SAVR using a biological aortic valve prosthesis and recorded...
The search yielded eight eligible observational studies covering 6727 patients overall. The lowest 0- to 12-month mortality was observed in patients with anticoagulation (2.0%, 95% CI 0.4-9.7%) and an...
Although this meta-analysis reveals that anticoagulation therapy has a beneficial tendency in terms of mortality at 1 year after biological SAVR and suggests potential advantages in continuing anticoa...
