Coronary Circulation

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Location and Orientation of the Heart

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Cardiac Catheterization III: Left Heart Catheterization

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Cardiac Catheterization II: Right Heart Catheterization

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Thoracic Aorta

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Background:

Curved planar reformation (CPR) is a common clinical technique for visualizing coronary arteries in medical images.
Accurate localization of coronary arteries is crucial for effective CPR generation.

Purpose of the Study:

To develop a fully automatic coronary artery centerline tracker to enhance the efficiency and accuracy of CPR image generation.
Introduce the COronary artery Centerline Tracker (COACT) framework.

Main Methods:

COACT integrates an ostium point finder (OPFinder) and an intersection point detector (IPDetector).
The framework utilizes a series of strategies to reconstruct the coronary artery centerline tree, starting from detected ostium points.

Main Results:

OPFinder achieved an average ostium point distance of 0.88 mm, comparable to inter-observer variability (0.85 mm).
IPDetector demonstrated an average overlap of 97.82% for intersection points, close to inter-observer agreement (98.50%).
The COACT framework achieved a 94.33% overlap for the entire coronary centerline tree, slightly below inter-observer agreement (98.39%).

Conclusions:

A fully automatic centerline tracking method for coronary CT angiography (CCTA) scans was successfully developed.
The COACT framework demonstrates satisfactory performance and is integrated into the TIMESlice medical image analysis platform.
