Wearable Hyperspectral Photoplethysmography Allows Continuous Monitoring of Exercise‐Induced Hypertension

Advanced Science, EarlyView.
A wearable hyperspectral photoplethysmography (HS‐PPG) is reported for continuous blood pressure (BP) monitoring. The HS‐PPG module integrates an ultrathin double‐folded solid immersion grating microspectrometer (DFSIG‐µSPEC), achieving a high spectral resolution of 3.4 nm.

Right ventricular dysfunction predicts outcome after transcatheter mitral valve repair for primary mitral valve regurgitation

European Journal of Heart Failure, Volume 24, Issue 11, Page 2162-2171, November 2022., 2022
RVD predicts outcome after M‐TEER for PMR. CI, confidence interval; HR, hazard ratio; PMR, primary mitral regurgitation; RVD, right ventricular dysfunction. Abstract Aims Right ventricular dysfunction (RVD), as expressed by right ventricular to pulmonary artery coupling, has recently been identified as a strong outcome predictor in patients undergoing ...

Double cardiac pseudoaneurysm in a postoperative patient

Türk Kardiyoloji Derneği Arşivi, 2015
A mitral-aortic intervalvular fibrosa pseudoaneurysm is a rare complication after aortic and mitral valve replacement and aortic root replacement. A left ventricular pseudoaneurysm after mitral valve replacement is also a rare complication.

Fish Swim Bladder‐Derived ECM Hydrogels Effectively Treat Myocardial Ischemic Injury through Immunomodulation and Angiogenesis

Advanced Science, EarlyView.
A unique hydrogel based on extracellular matrix from fish swim bladder, which is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure, is developed. It emerges as a multi‐effect factor profoundly influencing inflammation regulation, angiogenesis, and myocardial metabolism.

Same-Day Discharge After Transcatheter Native Aortic and Mitral Valve-in-Valve Replacement

JACC: Case Reports, 2020
Transcatheter aortic valve replacement has become the gold standard of care in the management of patients with severe aortic stenosis and transcatheter mitral valve-in-valve replacement seems to be an attractive alternative to redo surgery. We report the

A Design-Based Model of the Aortic Valve for Fluid-Structure Interaction [PDF]

, 2020
This paper presents a new method for modeling the mechanics of the aortic valve, and simulates its interaction with blood. As much as possible, the model construction is based on first principles, but such that the model is consistent with experimental observations.

Quality of life after aortic valve repair is similar to Ross patients and superior to mechanical valve replacement: a cross-sectional study

BMC Cardiovascular Disorders, 2016
BackgroundIn patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve-sparing

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

Advanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.
