简介：

Overview

This research aims to generate 3D models of the human cardiac venous system using contrast-computed tomography scans. The models will contribute to an anatomical database for designing cardiac devices.

Key Study Components

Area of Science

• Cardiac anatomy
• Medical imaging
• Device design

Background

• The human cardiac venous system is crucial for cardiac function.
• Existing methods for assessing venous anatomy have limitations.
• 3D reconstructions can enhance understanding of cardiac structures.
• This study aims to improve anatomical mapping without patient exposure to contrast agents or radiation.

Purpose of Study

• To create accurate 3D models of the cardiac venous system.
• To develop an anatomical database for cardiac device design.
• To improve techniques for mapping cardiac anatomy.

Methods Used

• Preparation of human heart specimens in end diastolic state.
• Cannulation of the coronary sinus with a venogram balloon catheter.
• Acquisition of contrast CT images of the cardiac venous system.
• Generation of 3D models from CT scans for anatomical measurements.

Main Results

• Successful generation of detailed 3D models of the cardiac venous system.
• Ability to obtain various anatomical measurements from the models.
• Demonstration of advantages over in vivo assessment methods.
