Transposition of the great arteries (TGA) is a congenital cardiac defect caused by an embryological discordance between the aorta and pulmonary trunk or by both atrioventricular and ventriculoarterial discordance—a condition often termed "double discordance."

The thermogravimetric data collected from a thermal reaction is compiled into a plot of mass or percentage of initial mass on the y axis versus either temperature or time on the x-axis. This plot, which is often smoothed, is referred to as a TGA curve.

2020年11月9日 · In this video, I have shown 2 methods about how to plot TGA and DSC spectra in a single graph using OriginLab software. The double X-axis is common for both ...

Transposition of the great arteries (TGA) is the most common cyanotic cardiac lesion in newborns, accounting for 5-10% of all congenital heart disease (CHD). The malformation occurs in about 20-30 per 100,000 live births and is seen more often in male babies. Without surgical correction, TGA is almost universally fatal during the first year of ...

Transposition of the great arteries (TGA) is a congenital conotruncal abnormality characterized by discordant connections between the ventricles and great arteries, with the aorta originating from the right ventricle (RV), and the pulmonary artery (PA) originating from the left ventricle (LV).

TGA because of its widespread availability and portability. Transthoracic echocardiography (TTE) with two-dimensional (2D) and Doppler echocardiography provides comprehensive anatomic and hemodynamic evaluation in the majority of patients with TGA and is usually the only modality required for preoperative eval-uation.

Thermogravimetric analysis (TGA) is a widely used thermal technique in the characterization of crystalline and amorphous pharmaceutical materials. TGA measures changes in sample mass with temperature within a controlled environment.

2025年2月5日 · TGA refers to the discordant ventriculo-arterial connection, where the aorta arises from the morphological RV, and the pulmonary artery arises from the morphological LV. The diagnosis and evaluation of both types of TGA (d-TGA and l-TGA) are covered in this chapter.

2025年1月4日 · Transposition of the great arteries (TGA), also known as transposition of the great vessels ... short axis views at the great vessels allow delineation of the spatial relationship between the great vessels and the coronary artery origins. in the most common orientation, the aorta will be anterior and slightly to the right of the pulmonary ...

2016年10月17日 · Parasternal long axis (PLAX) view is often the first view taken during echocardiography. Usually it visualizes the left ventricle, left atrium, right ventricular outflow region and aorta. Here we have a modified parasternal view to trace the great vessel arising from the left ventricle distally.
