Mitral Annulus Segmentation Using Deep Learning in 3-D Transesophageal Echocardiography.
IEEE journal of biomedical and health informatics
Dec 12, 2019
3D Transesophageal Echocardiography is an excellent tool for evaluating the mitral valve and is also well suited for guiding cardiac interventions. We introduce a fully automatic method for mitral annulus segmentation in 3D Transesophageal Echocardio...
Changes in cardiac function and hemodynamics during robot-assisted laparoscopic prostatectomy with steep head-down tilt: a prospective observational study.
BMC research notes
Jul 28, 2017
OBJECTIVE: Robot-assisted laparoscopic prostatectomy requires the patient to be placed in a steep head-down tilt. The aim of our study was to investigate changes in cardiac index and left ventricular end-diastolic volume in a steep had-down tilt. Thi...
Robotic Transcatheter Mitral Valve Replacement Using the Sapien XT in the Setting of Severe Mitral Annular Calcification.
Journal of cardiac surgery
Apr 5, 2016
We describe the use of the Sapien XT, placed in the mitral position using a totally endoscopic robotic approach in a 76-year-old man with extensive circumferential mitral calcifications and severe stenosis. The patient was at high risk for traditiona...
Marginal Space Deep Learning: Efficient Architecture for Volumetric Image Parsing.
IEEE transactions on medical imaging
Mar 7, 2016
Robust and fast solutions for anatomical object detection and segmentation support the entire clinical workflow from diagnosis, patient stratification, therapy planning, intervention and follow-up. Current state-of-the-art techniques for parsing volu...
A CNN Regression Approach for Real-Time 2D/3D Registration.
IEEE transactions on medical imaging
Jan 26, 2016
In this paper, we present a Convolutional Neural Network (CNN) regression approach to address the two major limitations of existing intensity-based 2-D/3-D registration technology: 1) slow computation and 2) small capture range. Different from optimi...
The Expanding Role of Endoscopic Robotics in Mitral Valve Surgery: 1,257 Consecutive Procedures.
The Annals of thoracic surgery
Aug 18, 2015
BACKGROUND: The role of robotic instruments in mitral valve (MV) surgery continues to evolve. The purpose of this study was to assess the safety, efficacy, and scope of MV surgery using a lateral endoscopic approach with robotics (LEAR) technique.
Design, testing and modelling of a novel robotic system for trans-oesophageal ultrasound.
The international journal of medical robotics + computer assisted surgery : MRCAS
Jul 31, 2015
BACKGROUND: Trans-oesophageal echocardiography (TOE) has been widely utilized for cardiac disease diagnosis and interventional procedure guidance. However, the TOE operator is required to manually manipulate the probe, often for long periods of time ...
Embolic Ischemic Cortical Stroke in a Young Flight Instructor with a Small Patent Foramen Ovale.
Aerospace medicine and human performance
Oct 1, 2024
BACKGROUND: Stroke in young patients is frequently associated with a patent foramen ovale (PFO). Controversy exists over whether the PFO is a cause, a risk factor, or an incidental finding. Estimating the individualized risk of stroke recurrence has ...
Deep learning networks in the segmentation of the left atrial appendage in 2D ultrasound: A comparative analysis.
Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Jul 1, 2023
Left atrial appendage (LAA) is the major source of thromboembolism in patients with non-valvular atrial fibrillation. Currently, LAA occlusion can be offered as a treatment for these patients, obstructing the LAA through a percutaneously delivered de...
