Heart Valves01:16

Heart Valves

4.6K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Chambers of the Heart

4.5K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.
Deoxygenated blood from the body is received in the right...

Thoracic Aorta01:15

Thoracic Aorta

465
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,...

The Aorta01:14

The Aorta

780
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

Anatomy of the Heart01:27

Anatomy of the Heart

108.6K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Summary

Quadricuspid aortic valve is a rare congenital heart defect, often causing aortic regurgitation. Diagnosis is typically confirmed with echocardiography, as seen in this case report of a 52-year-old woman.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Quadricuspid aortic valve (QAV) is a rare congenital anomaly.
  • It is frequently associated with aortic regurgitation, often necessitating surgical repair.
  • QAV can coexist with other congenital heart defects, including coronary anomalies and septal defects.

Observation:

  • This report details a 52-year-old female patient.
  • The diagnosis of QAV was established during surgery.
  • Intraoperative transesophageal echocardiography was the diagnostic modality used.

Findings:

  • The patient was diagnosed with a quadricuspid aortic valve.
  • The diagnosis was confirmed using intraoperative transesophageal echocardiography.
  • This highlights the utility of intraoperative echocardiography in diagnosing rare cardiac anomalies.

Implications:

  • Accurate and timely diagnosis of QAV is crucial for appropriate management.
  • Intraoperative echocardiography plays a vital role in confirming diagnoses during cardiac procedures.
  • Understanding the spectrum of associated anomalies is important for comprehensive patient care.
