Influence of Differential Calcification in the Descending Thoracic Aorta on Aortic Pulse Pressure

Journal of Patient-Centered Research and Reviews, 2017
Purpose: Multiple studies have shown pulse pressure (PP) to be a strong predictor of aortic calcification. However, no studies are available that correlate PP with aortic calcification at the segmental level.

Two-vessel off-pump coronary artery bypass grafting by left thoracotomy in a complex redo case [PDF]

, 2013
Introduction: The left thoracotomy approach is an alternative technique for coronary revascularization to avoid complications associated with re-sternotomy, such as injury to patent grafts, right ventricle, aorta, during re-sternotomy.

A Human Engineered Heart Tissue‐Derived Lipotoxic Diabetic Cardiomyopathy Model Revealed Early Benefits of Empagliflozin

Advanced Science, EarlyView.
This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

Optimal Extent of Lymph Node Dissection for Non‐Metastatic Colon Cancer by Tumor Location: Evaluation of the Therapeutic Value Index for Each Lymph Node Station

Annals of Gastroenterological Surgery, EarlyView.
Lymph node dissection of the main nodes along the feeding artery has a therapeutic value in early‐stage colon cancers. Meanwhile, the significance of #253 dissection for descending colon cancer requires further discussion. ABSTRACT Aims To determine the optimal extent of lymph node dissection for non‐metastatic colon cancer by tumor location based on ...

Automating the determination of wave speed using the pu-loop method [PDF]

, 2005
The PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves.

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

Advanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.
