Insights

Levoatriocardinal vein (LACV) is a rare cardiac anomaly, often linked to left-sided obstructive lesions. This study reviews 11 cases, highlighting diagnostic echocardiographic views and clinical presentations.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Levoatriocardinal vein (LACV) is a rare congenital anomaly connecting the pulmonary venous and cardinal systems.
  • It is infrequently encountered and often associated with other cardiac defects.

Purpose of the Study:

  • To describe the morphological and clinical characteristics of LACV.
  • To outline diagnostic methods for identifying LACV.
  • To review institutional experience with LACV cases.

Main Methods:

  • Retrospective review of 11 patients diagnosed with LACV between 2010 and 2014.
  • Echocardiography was the primary diagnostic tool to confirm LACV presence and assess associated lesions.
  • Evaluation included identification of left-sided obstruction and interatrial septum integrity.

Main Results:

  • 82% of patients were diagnosed under one year of age.
  • Nine patients presented with left-sided obstruction; two had normal intracardiac anatomy.
  • Echocardiography in specific views confirmed LACV originating from the left atrium in all cases.

Conclusions:

  • LACV is extremely rare and predominantly occurs with left-sided obstructive lesions.
  • Consideration of LACV is crucial in patients with left-sided obstructions.
  • LACV can also manifest in individuals with normal intracardiac anatomy and pulmonary venous return.

Development of the Heart01:27

Development of the Heart

The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Development of Blood Vessels01:07

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Coronary Circulation01:21

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...

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
