Anatomy of the Heart01:27

Anatomy of the Heart

93.3K
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.

Chambers of the Heart

10.0K
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.

Coronary Circulation01:21

Coronary Circulation

9.9K
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...

Anatomy of the Heart

6.0K
The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

1.3K
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Summary
This summary is machine-generated.

Surgical repair of double-chambered right ventricle is effective. The transatrial approach with pulmonary arteriotomy showed no complications, making it a suitable correction method for this condition, even with associated defects.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Surgery
  • Cardiac Anatomy

Background:

  • Double-chambered right ventricle is a rare congenital heart defect.
  • Surgical intervention is necessary for correction.
  • Associated cardiac anomalies are common.

Purpose of the Study:

  • To evaluate the effectiveness of two surgical approaches for double-chambered right ventricle repair.
  • To compare outcomes between longitudinal right ventriculotomy and transatrial approach with pulmonary arteriotomy.
  • To assess the long-term results of surgical correction.

Main Methods:

  • Retrospective analysis of 37 patients undergoing surgical repair between 1974 and 1993.
  • Patients divided into two groups: longitudinal right ventriculotomy (Group I) and transatrial approach with pulmonary arteriotomy (Group II).
  • Ventricular septal defects were closed with patches or sutures.

Main Results:

  • Group I (ventriculotomy) had one early death, 10 patients requiring inotropic support, and 2 reoperations for patch dehiscence.
  • Group II (transatrial approach) had no complications.
  • All 36 surviving patients were asymptomatic at long-term follow-up (6.5 +/- 3.1 years).

Conclusions:

  • The transatrial approach with pulmonary arteriotomy is a safe and effective method for correcting double-chambered right ventricle.
  • This approach is particularly suitable even when a perimembranous ventricular septal defect is present.
  • Surgical correction leads to excellent long-term outcomes.
