Insights

Conservative management of acute coronary syndrome (ACS) is possible when plaque erosion, not rupture, is identified. Intracoronary imaging is crucial for assessing ACS causes and guiding treatment decisions without stenting.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Cardiovascular Imaging

Background:

  • Percutaneous coronary intervention (PCI) with stenting is the standard treatment for acute coronary syndrome (ACS) resulting from culprit lesion stenting.
  • Plaque rupture is the predominant cause of ACS, but other pathologies like plaque erosion can also precipitate ACS.
  • Non-obstructive lesions or alternative mechanisms may allow for conservative management strategies.

Observation:

  • A case of acute coronary syndrome (ACS) was presented with symptoms suggestive of cardiac ischemia.
  • Intracoronary imaging revealed plaque erosion as the underlying pathology, with no significant obstructive coronary artery disease.
  • The patient's clinical presentation and imaging findings prompted consideration of non-invasive management.

Findings:

  • The patient was successfully managed conservatively without the need for stenting.
  • Plaque erosion was confirmed as the mechanism responsible for ACS in this case.
  • The absence of an obstructive lesion supported the decision for conservative treatment.

Implications:

  • This case underscores the critical role of intracoronary imaging in differentiating ACS etiologies.
  • Accurate assessment of underlying pathology can identify ACS cases amenable to conservative management, avoiding unnecessary stenting.
  • Integrating intracoronary imaging into ACS workup can personalize treatment strategies and potentially reduce procedural risks and healthcare costs.

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...

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...

Acute Coronary Syndrome I: Introduction01:30

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...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
