Insights

Percutaneous coronary intervention (PCI) for single coronary artery (SCA) disease is challenging but achievable. With expertise and proper hardware, successful PCI outcomes are possible in these rare congenital cases.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Interventional Cardiology

Background:

  • Single coronary artery (SCA) is a rare congenital anomaly with an incidence of 0.024%–0.066%.
  • Percutaneous coronary intervention (PCI) in patients with SCA and coronary artery disease (CAD) presents significant technical challenges.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of PCI in patients with SCA and significant CAD.
  • To analyze the technical aspects and success rates of PCI procedures in this unique patient population.

Main Methods:

  • A retrospective analysis of cardiac catheterization procedures over 15 years identified 12 cases of SCA (0.084% incidence).
  • Angiographic "dot and eye" method and CT scans were used to determine coronary artery courses, classified by modified Lipton criteria.
  • PCI was performed using standard protocols for significant coronary artery stenosis.

Main Results:

  • Nine out of 12 SCA patients underwent PCI for significant CAD, with a mean age of 63.8 years.
  • Eleven successful PCI procedures were performed, including complex lesions like left main, bifurcation, chronic total occlusion, and multi-vessel disease.
  • Intravascular imaging and rotablation were utilized in select cases for complex calcified lesions.

Conclusions:

  • PCI in SCA patients is technically demanding, requiring specialized expertise and experience.
  • Careful hardware selection and technical proficiency are crucial for simplifying the procedure and achieving optimal results in SCA patients.

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...

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...
