Paradoxical Normal‐Flow Aortic Stenosis Despite Reduced Left Ventricular Ejection Fraction: Insights From the Randomized COMPARE‐TAVI 1 Trial

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The hemodynamic profile and remodeling patterns of paradoxical low‐flow, low‐gradient aortic stenosis are well understood. However, some patients with severe aortic stenosis exhibit eccentric remodeling with enlarged left ventricular cavities,

Delayed Time to Peak Velocity Is Useful for Detecting Severe Aortic Stenosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundTime to peak velocity (TPV) is an echocardiographic variable that can be easily measured and reflects a late peaking murmur, a classic physical finding suggesting severe aortic stenosis (AS).

Cardiac Imaging for Assessing Low-Gradient Severe Aortic Stenosis

JACC: Cardiovascular Imaging, 2017
Up to 40% of patients with aortic stenosis (AS) harbor discordant Doppler-echocardiographic findings, the most common of which is the presence of a small aortic valve area (≤1.0 cm2) suggesting severe AS, but a low gradient (

Comprehending the Membrane Properties for Emulation in Organs‐on‐a‐Chip

Advanced NanoBiomed Research, EarlyView.
The advent of organ‐on‐chip models allows closer emulation of in vivo conditions, leading to effective, less costly, and specific drugs. Although a number of membrane‐based on‐chip models exist, better emulating functional models need to be devised for organ simulations.

Severe Supravalvular Aortic Stenosis Treated With Double Patch Aortoplasty: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Severe supravalvular aortic stenosis in a young patient is a rare but critical condition requiring timely diagnosis and intervention. We report a 15‐year‐old girl presenting with exertional dyspnea, chest pain, and palpitations. Echocardiography and multidetector computed tomography (MDCT) confirmed severe supravalvular aortic stenosis ...

Heyde Syndrome: A Literature Review

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aims Heyde syndrome, a triad of anemia from gastrointestinal (GI) bleeding, aortic valve stenosis, and acquired von Willebrand syndrome, primarily affects individuals over 65. Management requires a multidisciplinary approach, including medical therapy, endoscopic intervention, and valve replacement.

Cardiac Resynchronization Therapy: Reconsidering Its Essence as a Treatment for Electrical Dyssynchrony in Heart Failure

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Flow of cardiac resynchronization therapy (CRT) in heart failure management. Heart failure (HF) patients with electrical dyssynchrony are first identified through screening. If electrical dyssynchrony contributes to HF deterioration, CRT is initiated to improve electrical synchrony.

Submaximal 2‐day cardiopulmonary exercise testing to assess exercise capacity and post‐exertional symptom exacerbation in people with long COVID

Experimental Physiology, Volume 111, Issue 2, Page 435-448, 1 February 2026.
Abstract Long COVID has a complex pathology and a heterogeneous symptom profile that impacts quality of life and functional status. Post‐exertional symptom exacerbation (PESE) affects one‐third of people living with long COVID, but the physiological basis of impaired physical function remains poorly understood. Sixty‐eight people (age (mean ± SD): 50 ±

Immediate Outcomes of Aortic Valve Neocuspidization with Glutaraldehyde-treated Autologous Pericardium: a Multicenter Study

Brazilian Journal of Cardiovascular Surgery
Objective: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. Methods: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 ...

Calcification Characteristics of Low-Flow Low-Gradient Severe Aortic Stenosis in Patients Undergoing Transcatheter Aortic Valve Replacement

Cardiology Research and Practice, 2015
Low-flow low-gradient severe aortic stenosis (LFLGAS) is associated with worse outcomes. Aortic valve calcification patterns of LFLGAS as compared to non-LFLGAS have not yet been thoroughly assessed.
