Insights

Coronary subclavian steal syndrome is a rare complication after heart bypass surgery. This condition, caused by blocked arteries near the graft, leads to chest pain and requires diagnosis via angiography.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Interventional Cardiology

Background:

  • Coronary subclavian steal syndrome (CSSS) is a rare cause of ischemia in patients post-myocardial revascularization.
  • It results from subclavian artery stenosis or compression near the internal mammary artery (IMA) graft.

Purpose of the Study:

  • To present a clinical case of CSSS in a patient experiencing post-operative angina.
  • To highlight the diagnostic findings and implications of this rare complication.

Main Methods:

  • Case report of a patient with a history of non-ST elevation myocardial infarction and triple coronary bypass.
  • Clinical evaluation including an ischemic test and diagnostic coronary angiography.

Main Results:

  • The patient presented with effort angina post-coronary artery bypass grafting.
  • Coronary angiography identified significant stenosis in the left subclavian artery proximal to the IMA graft, confirming CSSS.

Conclusions:

  • CSSS is a critical consideration in patients with angina after coronary revascularization.
  • Early diagnosis through angiography is essential for managing this rare but significant complication.

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 V: Nursing Management

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

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...
