Diagnosis of mitral insufficiency using impedance cardiography technique ICG

Journal of Electrical Bioimpedance, 2016
Impedance cardiography (ICG) is a non-invasive tool for assessing the hemodynamic parameters. It has been used for diagnosing several cardiovascular diseases, such as heart failure, cardio-myopathy, and valvular diseases. Particularly, the valvular heart

Open-heart transseptal transcatheter mitral valve implantation with mitral annular calcification [PDF]

Journal of Cardiology Cases, 2020
Mitral valve replacement (MVR) using a prosthesis of transcatheter aortic valve implantation for mitral annular calcification (MAC) is an alternative procedure which is very different from a conventional MVR and is safe. Acceptable results including mortality and morbidity have been reported.

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

Reconstructing Coherent Functional Landscape From Multi‐Modal Multi‐Slice Spatial Transcriptomics by a Variational Spatial Gaussian Process

Advanced Science, EarlyView.
This study introduces stVGP, a variational spatial Gaussian process framework for multi‐modal, multi‐slice spatial transcriptomics. By integrating histological and genomic data through hybrid alignment and attention‐based fusion, stVGP reconstructs coherent 3D functional landscapes.

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.
