A New Semi-supervised Learning Benchmark for Classifying View and Diagnosing Aortic Stenosis from Echocardiograms [PDF]

arXiv, 2021
Semi-supervised image classification has shown substantial progress in learning from limited labeled data, but recent advances remain largely untested for clinical applications. Motivated by the urgent need to improve timely diagnosis of life-threatening heart conditions, especially aortic stenosis, we develop a benchmark dataset to assess semi ...

Computed Tomography Aortic Valve Calcium Scoring in Patients With Aortic Stenosis

Circulation Cardiovascular Imaging, 2018
Background— Computed tomography aortic valve calcium scoring (CT-AVC) holds promise for the assessment of patients with aortic stenosis (AS). We sought to establish the clinical utility of CT-AVC in an international multicenter cohort of patients ...

Transcatheter Aortic Valve Replacement (TAVR) [PDF]

, 2023
Transcatheter aortic valve replacement (TAVR) is becoming the gold standard when repairing aortic stenosis compared to surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement is minimally invasive.

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

Advanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.

The brain‐before‐heart strategy for coronary artery bypass grafting in the severely atherosclerotic aorta: A single‐institution experience

Clinical Cardiology, Volume 45, Issue 12, Page 1264-1271, December 2022., 2022
Abstract Background Severe atherosclerosis of the ascending aorta (SAA) in patients undergoing surgical revascularization by coronary artery bypass grafting (CABG) is becoming an increasing problem as more elderly patients are diagnosed with coronary artery disease.

Successful percutaneous balloon dilatation of supravalvular aortic membrane

Heart Views, 2019
Supravalvular aortic stenosis is the least common type of left ventricular outflow tract obstruction. Primary balloon dilatation of membranous supravalvular aortic stenosis was performed in a 10-year-old male child with a remarkable reduction in systolic

A remote hypertension management program clinical algorithm

Clinical Cardiology, Volume 45, Issue 12, Page 1147-1162, December 2022., 2022
Abstract Introduction Hypertension is the leading risk factor for death, affecting over one billion people worldwide, yet control rates are poor and stagnant. We developed a remote hypertension management program that leverages digitally transmitted home blood pressure (BP) measurements, algorithmic care pathways, and patient–navigator communications ...

Staging classification of aortic stenosis based on the extent of cardiac damage

European Heart Journal, 2017
Aims In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities.

Predicting progression of aortic stenosis by measuring serum calcification propensity

Clinical Cardiology, Volume 45, Issue 12, Page 1297-1302, December 2022., 2022
Abstract Background The aim of this prospective, double‐blinded study in patients with aortic sclerosis was to determine whether a new calcification propensity measure in the serum could predict disease progression. Methods We included 129 consecutive patients with aortic sclerosis as assessed during a routine clinical echocardiographic exam. Clinical,
