Insights

Cor Triatriatum is a rare congenital heart anomaly. Cardiac CT effectively identifies Cor Triatriatum Sinister and Dexter, aiding in diagnosis and management of associated cardiac conditions.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Congenital Heart Disease

Background:

  • Cor Triatriatum is a rare congenital cardiac anomaly involving atrial septation.
  • Preoperative diagnosis is crucial for effective patient management.
  • This condition can manifest in the left (Cor Triatriatum Sinister - CTS) or right atrium (Cor Triatriatum Dexter - CTD).

Purpose of the Study:

  • To review imaging findings of Cor Triatriatum.
  • To classify the subtypes of Cor Triatriatum.
  • To identify associated congenital cardiac anomalies influencing patient management.

Main Methods:

  • Retrospective review of 10 Cor Triatriatum patients from EHR database.
  • Cardiac CT imaging analysis for congenital heart disease.
  • Analysis of medical records and imaging findings.

Main Results:

  • Nine patients (90%) had CTS, one (10%) had CTD.
  • CTS Type II and III were observed, with varying membrane orifice sizes.
  • Pulmonary vein dilation and common associated anomalies like ASD and VSD were noted.

Conclusions:

  • Cardiac CT provides excellent pre-operative evaluation for Cor Triatriatum.
  • CT is effective for diagnosing, classifying, and identifying associated anomalies and complications.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
