Insights

A high coronary artery calcium score from multidetector computed tomography (MDCT) can predict the need for rotational atherectomy (rotablation) during percutaneous coronary intervention (PCI). This helps in planning complex PCI procedures for calcified lesions.

Area of Science:

  • Cardiovascular Imaging
  • Interventional Cardiology
  • Medical Diagnostics

Background:

  • Rotational atherectomy (rotablation) is a technique used in percutaneous coronary intervention (PCI) for complex and calcified coronary lesions.
  • Predicting the need for rotablation is crucial for optimizing PCI outcomes.

Purpose of the Study:

  • To evaluate the utility of per-lesion coronary artery calcium score from multidetector computed tomography (MDCT) in predicting the requirement for rotablation during PCI.
  • To establish MDCT-derived calcium scoring as a predictive tool for rotablation necessity.

Main Methods:

  • Retrospective analysis of MDCT and quantitative coronary angiography (QCA) data in 116 patients undergoing first PCI for stable angina.
  • Evaluation of 168 target lesions to correlate MDCT calcium scores and lesion characteristics with rotablation use.

Main Results:

  • Patients requiring rotablation had significantly higher SYNTAX and total calcium scores.
  • Per-lesion MDCT parameters, including calcium score (≥453) and calcification arc (≥270), predicted rotablation.
  • A high per-lesion calcium score was an independent predictor of rotablation (OR 31.3, 95% CI 2.8-345), with 93% sensitivity and 88% specificity.

Conclusions:

  • MDCT-derived extent of target lesion calcification is a valuable predictor of rotablation need during PCI.
  • This simple marker of calcified plaque aids in procedural planning for complex coronary interventions.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
