Summary
Coronary stent fracture, a rare complication of stenting, can cause unstable angina. Early recognition is key for prompt treatment of this potentially serious issue.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomedical Engineering
Background:
- Coronary artery stenting is a common procedure to treat coronary artery disease.
- Stent fracture is a rare but serious complication that can lead to adverse cardiac events.
- Non-specific symptoms of stent fracture can delay diagnosis and treatment.
Observation:
- A 61-year-old male presented with unstable angina.
- The patient had undergone elective percutaneous coronary intervention (PCI) for in-stent restenosis two weeks prior.
- Coronary stent fracture was identified as the cause of the patient's symptoms.
Findings:
- The case highlights a stent fracture occurring within two weeks of PCI.
- Unstable angina was the presenting symptom, directly linked to the fractured stent.
- This case underscores the potential for rapid onset of complications after stenting.
Implications:
- Physicians must maintain a high index of suspicion for stent fracture in patients with relevant history and symptoms.
- Awareness of this complication is crucial for timely diagnosis and intervention.
- Prompt recognition and management of coronary stent fracture can prevent severe cardiac events.

01:30Acute 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...
01:27Coronary 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...
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:26Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
01:28Acute Coronary Syndrome IV: Interprofessional Care
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
