Transapical implantation of a novel self-expanding sutureless aortic valve prosthesis

, 2010
To date, transapical aortic valve implantation has required a balloon-expandable stented valve prosthesis. More recently, a novel self-expanding sutureless stented bovine pericardial prosthesis has been developed which allows rapid aortic valve ...

Rapidly Progressive Bilateral Infective Endocarditis Involving Prosthetic Material After Repaired Tetralogy of Fallot: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Infective endocarditis after repaired tetralogy of Fallot can rapidly progress when prosthetic material is involved. We report bilateral multivalvular endocarditis undetected by transthoracic echocardiography but identified by transesophageal echocardiography.

Culture‐Negative Septic Pulmonary Embolism Secondary to Lower‐Limb Cellulitis Following Recent Dengue Fever Complicated by Hydropneumothorax: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Secondary bacterial infection and septic pulmonary embolism should be considered in patients recovering from dengue fever who develop focal soft‐tissue infection, respiratory symptoms, or markedly elevated inflammatory markers. Characteristic radiological findings may establish the diagnosis even when blood cultures are negative and infective ...

Design criteria for the trileaflet mechanical heart valve

, 2010
碩士本研究的目的是設計出一個理想的人工心瓣。雖然人工心瓣發展已經超過半個世紀，但目前臨床上所使用的機械心瓣還是存在血栓與溶血等缺點，而生物心瓣卻有不耐用的問題。本文利用分析各種三葉片機械心瓣的專利和相關文獻，進而提出全新的改良設計。新設計的葉片與環座是完全以自由曲面所建構而成，外形平順完整而沒有突出的支架，具有圓滑的轉軸，使葉片能夠靈活地轉動。 然後以鈦合金製作實驗原型，提供實驗團隊進行體外流場實驗分析，以驗證新設計的流場性能表現與發展可行性。然後根據新設計的概念，提出美國專利申請 ...

Thrombus‐Induced Prosthetic Valve Dysfunction Demonstrating Hypo‐Attenuated Leaflet Thickening: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Hypo‐attenuated leaflet thickening (HALT) is an important and potentially underrecognized cause of late bioprosthetic valve dysfunction after surgical AVR. Multimodal imaging, including echocardiography and electrocardiogram‐gated computed tomography, is essential for diagnosis, and timely surgical or medical intervention can effectively ...

Detection of fiber structure and calcification in xenogeneic pericardium by OCT

Current Directions in Biomedical Engineering
Aortic valve (AV) stenosis is the most treated heart valve disease and the only curative treatment is the surgical AV replacement or the transcatheter prosthesis implantation.

Fungal Antimicrobial Resistance: Mechanisms, Drivers, and Global Clinical Burden

ChemFoodChem, Volume 2, Issue 3, September 2026.
ABSTRACT Fungal antimicrobial resistance (AMR) is a growing concern for world health caused by an increase in multidrug‐resistant infections, an increase in environmental reservoirs, and the ineffectiveness of current antifungal treatments. Fungal infections continue to be largely excluded from AMR initiatives while causing over 1.6 million deaths ...
