Insights

Cor triatriatum dexter (CTD) is a rare congenital heart defect. Surgical removal of the dividing membrane and right atrial reduction successfully treated a 36-year-old female patient with palpitations.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Cor triatriatum dexter (CTD) is a rare congenital cardiac anomaly.
  • It can present with diverse clinical manifestations across all age groups.
  • Understanding CTD's varied presentations is crucial for timely diagnosis and management.

Observation:

  • A 36-year-old female presented with palpitations.
  • The palpitations were attributed to a giant right atrium (RA).
  • Diagnostic evaluation confirmed the presence of Cor triatriatum dexter.

Findings:

  • Successful surgical excision of the intra-atrial membrane was performed.
  • Right atrial reduction surgery was also conducted.
  • The patient's palpitations were resolved post-operatively.

Implications:

  • This case highlights the successful surgical management of symptomatic Cor triatriatum dexter in an adult.
  • Surgical intervention can effectively alleviate symptoms associated with giant right atrium secondary to CTD.
  • Early diagnosis and surgical correction are vital for improving outcomes in patients with this rare cardiac anomaly.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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.
Deoxygenated blood from the body is received in the right...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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...

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...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
