What Causes Congenital Heart Defects?

Despite much research, in the majority of cases, Congenital Heart Defects (CHD) occur without any known cause. This is one reason the incidence has remained fairly constant at 7 to 8 cases per 1000 live births over decades, while other forms of heart disease have been declining in frequency. We know the causes of some […]

Truncus arteriosus is a rare complex birth defect of the heart in which only one artery leaves the heart, instead of the normal pattern where two great arteries – the aorta and the pulmonary artery – carry blood away from the heart. In truncus arteriosus, a single large arterial trunk […]

Single Ventricle

What is the heart defect called Single Ventricle ? While the normal heart has two ventricles, in some birth defects, one of these ventricles may be absent or poorly developed. This condition is called Single Ventricle or Univentricular heart. The ventricular structure may resemble the normal left ventricle or the normal right ventricle. Sometimes, it […]

So if you don’t, console yourself that you are in distinguished company! What is […]

The word “pulmonary” denotes “to do with the lungs”. The pulmonary valve is located between the right ventricle and the pulmonary artery. It regulates blood […]

Transposition of Great Arteries – TGA

I hope you still remember about the great arteries of the body, and the chambers of the heart from which they arise. In this article, we will discuss the condition called Transposition of the Great Arteries (TGA) in which these great vessels are inter-changed in position. Here’s what you’ll learn about: What is Transposition of […]
