Insights

Intravascular ultrasound (IVUS) offers superior coronary assessment compared to angiography, accurately measuring vessel size and plaque. Its pre-procedural use, especially for complex lesions, may optimize intervention strategies and improve patient outcomes.

Area of Science:

  • Cardiovascular imaging
  • Interventional cardiology
  • Medical device technology

Background:

  • Coronary angiography underestimates lesion severity and misses calcified plaques.
  • Intravascular ultrasound (IVUS) provides accurate vessel sizing and detailed plaque analysis.
  • Limited data exists on pre-procedural IVUS impact and its use with drug-eluting stents.

Purpose of the Study:

  • To evaluate the impact of pre-procedural IVUS on interventional strategy and clinical outcomes.
  • To highlight the utility of IVUS in complex coronary lesion assessment.
  • To advocate for increased IVUS utilization in interventional cardiology.

Main Methods:

  • Review of existing literature on IVUS in coronary interventions.
  • Analysis of clinical experience with IVUS guidance.
  • Comparison of IVUS capabilities versus standard coronary angiography.

Main Results:

  • IVUS accurately quantifies vessel dimensions and lesion severity.
  • IVUS enables detailed plaque characterization, including calcification.
  • Pre-procedural IVUS can guide intervention strategy for complex cases.

Conclusions:

  • IVUS is a valuable tool for comprehensive coronary assessment.
  • Liberal use of IVUS, particularly for complex lesions, can lead to optimal stent implantation.
  • Optimized interventional results guided by IVUS may positively impact clinical outcomes.

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Ultrasound I: Abdominal Ultrasonography

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
