Abstract

Insights

Pseudoaneurysm from the mitral aortic intervalvular fibrosa (P-MAIVF) is rare. Cardiac CT is definitive for diagnosing P-MAIVF, especially when transesophageal echocardiography is contraindicated.

Area of Science:

  • Cardiovascular Imaging
  • Cardiac Surgery
  • Congenital Heart Disease

Background:

  • Pseudoaneurysm arising from the mitral aortic intervalvular fibrosa (P-MAIVF) is a rare cardiac anomaly.
  • Multiple factors can contribute to the development of P-MAIVF.
  • Typically diagnosed via echocardiography and confirmed with cardiac CT.

Observation:

  • A case of congenital P-MAIVF communicating with the left atrium (LA) is presented.
  • The patient had an aberrant right subclavian artery.
  • Misdiagnosed as mitral regurgitation (MR) on transthoracic echocardiogram (TTE) due to contraindications for transesophageal echocardiogram (TEE).

Findings:

  • Cardiac CT confirmed the congenital P-MAIVF.
  • The patient had hemophilia, adding complexity to diagnosis and management.
  • Cardiac CT provided definitive anatomical assessment and diagnosis.

Implications:

  • Cardiac CT is crucial for definitive diagnosis of P-MAIVF.
  • CT is valuable for anatomical assessment and lesion confirmation.
  • CT is essential for primary diagnosis in patients with contraindications to TEE.

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...

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...

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...

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...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
