Curved Bistable Origami‐Inspired Flexible Transcatheter Mitral Valve Clamping

Advanced Science, EarlyView.
A lightweight bistable curved origami dilator combines reversible deformation and high stability, offering a promising solution for minimally invasive mitral valve repair. Abstract Curved origami exhibits remarkable potential for minimally invasive medical applications owing to its unique geometric programmability and mechanical tunability. Building on

Macrophage lineages in heart valve development and disease.

Cardiovascular Research, 2020
Heterogeneous macrophage lineages are present in the aortic and mitral valves of the heart during development and disease. These populations include resident macrophages of embryonic origins and recruited monocyte-derived macrophages prevalent in disease.

Mitral Valve Reconstruction in the Patient with Heart Failure [PDF]

Heart Failure Reviews, 2001
Secondary MR is a complication of end-stage cardiomyopathy and is associated with a poor prognosis and is due to progressive mitral annular dilation and alteration in LV geometry. A vicious cycle of continuing volume overload, ventricular dilation, progression of annular dilation, increased LV wall tension and worsening MR and CHF occur.

Which Method Best Predicts Postoperative Complications: Deep Learning, Machine Learning, or Conventional Logistic Regression?

Annals of Gastroenterological Surgery, EarlyView.
Deep learning has shown promise in predicting postoperative complications, particularly when using image or time‐series data. However, on tabular clinical data such as the NCD, it often underperforms compared to conventional machine learning. Integrating multimodal data may enhance predictive accuracy and interpretability in surgical care.

Combined Aortic and Mitral Valve Stenosis in Mucopolysaccharidosis Syndrome Type I-S: A Report of a Rare Case

Journal of Tehran University Heart Center, 2021
Mucopolysaccharidosis (MPS) syndrome is an inherited metabolic disorder. In more than half of the patients with MPS syndrome, heart valve involvement is reported; however, combined aortic and mitral valve stenosis in MPS syndrome type I-S is very rare ...

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Left Ventricular Trabeculations Decrease the Wall Shear Stress and Increase the Intra-Ventricular Pressure Drop in CFD Simulations [PDF]

, 2018
The aim of the present study is to characterize the hemodynamics of left ventricular (LV) geometries to examine the impact of trabeculae and papillary muscles (PMs) on blood flow using high performance computing (HPC). Five pairs of detailed and smoothed
