As we will show, these works from the 19th and early 20th centuries reflect topics still relevant today, namely the aetiology of cardiac malformations, clinicopathologic correlations, attempts at classification, and lack of effective treatments. Attention to their content could have served to ameliorate controversies, some of them ongoing.
Aortic insufficiency (AI), also known as aortic regurgitation (AR), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.As a consequence, the cardiac muscle is forced to work harder than normal.
However, to the best of our knowledge, there is no published case report of Pentalogy of Fallot with a single coronary artery. Herein, we introduce a 22-year-old female patient diagnosed via echocardiography and cardiac catheterization preoperatively as Pentalogy of Fallot with a single coronary artery arising from the left coronary sinus.
Truncus arteriosus or Persistent truncus arteriosus This is a rare congenital cardiac anomaly, in which the aorta, the coronary arteries, and the pulmonary artery arise from a common arterial trunk (the truncus arteriosus). This single arterial trunk is positioned above the ventricular septum and has one valve (the truncal valve). The truncal.
In the malalignment type of outlet defect, there is an abnormal relationship between the atrial and ventricular septa or between individual components of the ventricular septum with overriding of atrioventricular valves. Malalignment defects are typically seen in tetralogy of Fallot, truncus arteriosus, and double-outlet right ventricle.
An atrial septal defect (ASD) is an opening in the interatrial septum, causing a left-to-right shunt and volume overload of the right atrium and right ventricle. Children are rarely symptomatic, but long-term complications after age 20 yr include pulmonary hypertension, heart failure, and atrial.
Dextrocardia should be recognized on the preprocedural chest radiograph (Fig. 27-39), particularly because its presence may affect on which side an ICD system may be placed.It is important to note the position of the stomach bubble on the chest radiograph in patients with dextrocardia. In those with situs inversus totalis, in whom the normal right-versus-left position of all organs is.
A ventricular septal defect (VSD) is an opening in the interventricular septum, causing a shunt between ventricles. Large defects result in a significant left-to-right shunt and cause dyspnea with feeding and poor growth during infancy. A loud, harsh, holosystolic murmur at the lower left sternal.

List tetralogy of Fallot (most common), transposition of the great arteries, persistent truncus arteriosus, and tricuspid atresia as the four most important forms of congenital cyanotic heart disease, and clearly explain the abnormal anatomy and physiology of each. Explain the seriousness of the right-to-left shunt, the most dreaded.
Truncus arteriosus (also known as persistent truncus arteriosus) is a rare cyanotic congential heart defect in which an infant is born with one large vessel - rather than two smaller vessels - leading from the heart. Medical Expedited Adoption organized by Paul Staley Peds See more.
Truncus arteriosus(TA) is a rare congenital heart defect with serious complications. PDA (patent ductus arteriosis) is a naturally occurring opening between the pulmonary artery and the aorta of the heart.

Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in.
Truncus arteriosus. NO. Truncus arteriosus (TRUNG-kus ahr-teer-e-O-sus) is a rare heart defect that's present at birth (congenital). If your baby has truncus arteriosus, it means that one large blood vessel leads out of the heart. Normally, there are two separate vessels coming out of the heart.

Sep 11, 2016 - Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress. It is most commonly observed in isolation but can be associated with other cardiovascular abnormalities including atrial septal defect, bicuspid aortic valve, coarctation of aorta, coronary sinus.
The goal of this statement is to review available literature and to put forth a scientific statement on the current practice of fetal cardiac medicine, including the diagnosis and management of fetal cardiovascular disease. Fetal cardiac medicine has evolved considerably over the past 2 decades.
