Insights

Double-chambered right ventricle (DCRV) is rare, diagnosed via echocardiography. Surgical treatment yields excellent results, improving symptoms and function in most patients with this congenital heart defect.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Double-chambered right ventricle (DCRV) is a rare congenital heart anomaly, accounting for 0.5% of all congenital cardiopathies.
  • Clinical presentation varies, with some patients asymptomatic and others experiencing symptoms from infancy to adulthood.

Purpose of the Study:

  • To characterize the clinical and echocardiographic features of 11 patients diagnosed with DCRV.
  • To evaluate the outcomes of surgical intervention for DCRV.

Main Methods:

  • Retrospective review of 11 DCRV patients.
  • Data collection included medical history, chest radiography, electrocardiography, and transthoracic echocardiography.

Main Results:

  • Median age was 10 years; 36.45% were asymptomatic at diagnosis.
  • Echocardiography confirmed DCRV due to a muscular band in all patients.
  • Common associated anomalies included VSD, PFO, subaortic stenosis, and Tetralogy of Fallot.
  • Seven patients underwent surgery, with 6 achieving NYHA Class I post-operatively.

Conclusions:

  • DCRV diagnosis is best achieved through echocardiography.
  • Worsening NYHA functional class is a predominant symptom, with potential for progressive obstruction.
  • Surgical treatment in this series demonstrated excellent mid-term hemodynamic and functional outcomes for 91% of patients.

Chambers of the Heart01:16

Chambers of the Heart

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.

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 tube by...
Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

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...
Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
Anatomy of the Heart01:27

Anatomy of the Heart

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.

Anatomy of the Heart

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.
