Insights

Incomplete cor triatriatum dexter (iCTD) is common during interatrial shunt closure, affecting over 5% of patients. Recognizing iCTD and venous valve remnants is crucial for procedural safety and device placement in the right atrium.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Interventional Cardiology

Background:

  • Cor triatriatum dexter (CTD) is a congenital anomaly where the right atrium is divided by a membrane.
  • Incomplete CTD (iCTD) can result from prominent venous valve remnants like the Eustachian valve (EV) or Chiari network (CN).
  • These anomalies may impact procedures like interatrial shunt closure.

Purpose of the Study:

  • To assess the incidence of EV/CN and iCTD in patients undergoing interatrial shunt transcatheter closure.
  • To evaluate the clinical and technical implications of these findings during procedures.

Main Methods:

  • Retrospective analysis of a single-center registry.
  • Inclusion of 580 consecutive patients undergoing intracardiac echocardiography-aided interatrial shunt catheter-based closure over 12 years.
  • Assessment of iCTD, EV/CN prevalence, shunt grade, right ventricle diameter, and intraprocedural complications.

Main Results:

  • iCTD was diagnosed in 5.2% of patients with Patent Foramen Ovale (PFO) and 5.6% of patients with Atrial Septal Defect (ASD).
  • Prominent EV/CN were found in 51.1% of PFO patients and 13.7% of ASD patients.
  • iCTD was associated with a higher shunt grade in PFO patients and larger right ventricle diameter in ASD patients, and linked to intraoperative complications in 45.1% of cases.

Conclusions:

  • Incomplete CTD is frequently observed during interatrial shunt closure procedures.
  • Awareness of iCTD and associated venous structures is essential for safe and effective device-based interventions in the right atrium.

Mitral Stenosis II: Clinical features and Diagnostic Tests01:23

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...

Acute Coronary Syndrome III: Diagnostic Studies

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...

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 Regurgitation II: Clinical Features and Diagnostic Tests

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
