Transcatheter Aortic Valve Implantation in Dialysis Patients [PDF]

, 2012
Background/Aims: Transcatheter aortic valve implantation (TAVI) has emerged as a new therapeutic option for high-risk patients. However, dialysis patients were excluded from all previous studies.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Patient-specific image-based computer simulation for theprediction of valve morphology and calcium displacement after TAVI with the Medtronic CoreValve and the Edwards SAPIEN valve [PDF]

, 2016
AIMS: Our aim was to validate patient-specific software integrating baseline anatomy and biomechanical properties of both the aortic root and valve for the prediction of valve morphology and aortic leaflet calcium displacement after TAVI.

Endoscopic Aortic Valve Replacement

The Heart Surgery Forum, 2005
During the last 8 years, many different approaches for minimally invasive aortic valve surgery have emerged. We have developed a technique that enables total endoscopic aortic valve replacement with port access, via a small right lateral thoracotomy with only soft tissue retraction and minimally invasive aortic crossclamping. The operation is performed

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Awake Surgical Mitral Valve Repair after Transcatheter Aortic Valve Replacement

The Thoracic & Cardiovascular Surgeon Reports, 2021
Transcatheter aortic valve replacement has become a popular choice for cases with severe aortic stenosis. However, when severe mitral regurgitation is comorbid in high-risk patients with severe aortic stenosis, therapeutic options must be weighed for ...

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Surgical treatment for accidentally discovered pseudoaneurysm of the mitral-aortic intervalvular fibrosa with bicuspid aortic valve, ascending aortic aneurysm, and myocardial ischemia: a case report

The Cardiothoracic Surgeon, 2021
Background Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare complication of infective endocarditis and aortic valve replacement. Ruptured P-MAIVF and angina due to compression of the coronary arteries are severe complications
