Insights

A 75-year-old woman experienced cardiac tamponade due to a ventricular aneurysm. Cardiac multislice computed tomography aided in diagnosing coronary artery disease and cardiac rupture, leading to successful surgery.

Area of Science:

  • Cardiology
  • Cardiovascular Surgery
  • Diagnostic Imaging

Background:

  • Cardiac tamponade is a life-threatening condition often caused by fluid accumulation around the heart.
  • Myocardial infarction can lead to complications such as ventricular aneurysms and cardiac rupture.
  • Early and accurate diagnosis is crucial for managing acute cardiovascular events.

Observation:

  • A 75-year-old female presented with hypotension and syncope secondary to cardiac tamponade.
  • Electrocardiography showed ST elevation, and laboratory tests revealed elevated cardiac biomarkers.
  • Cardiac catheterization identified significant coronary artery stenosis and a ventricular aneurysm.

Findings:

  • Cardiac multislice computed tomography (MSCT) suggested a ventricular pseudoaneurysm likely resulting from myocardial infarction.
  • The patient had 75% stenosis in the left anterior descending coronary artery and 99% stenosis in a diagonal branch.
  • Aneurysmectomy and coronary artery bypass graft surgery were successfully performed.

Implications:

  • Cardiac multislice computed tomography is a valuable tool for evaluating coronary artery disease and diagnosing cardiac rupture.
  • Prompt surgical intervention can effectively treat ventricular aneurysms and related complications.
  • This case highlights the importance of advanced imaging in complex cardiovascular presentations.

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...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

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...
