Wire entanglement to retrieve a dislodged stent from the proximal right coronary artery

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Cardiovascular disease remains a leading cause of mortality worldwide.
• Diabetes mellitus and hypertension are significant risk factors for coronary artery disease.
• Non-ST-elevation myocardial infarction (NSTEMI) represents a critical manifestation of acute coronary syndrome.

Observation:

• The patient, a 70-year-old female with a history of diabetes and hypertension, presented with symptoms indicative of myocardial infarction.
• Diagnostic evaluation included coronary angiography to assess coronary artery patency.
• The angiogram identified a significant obstructive lesion in the mid-right coronary artery (RCA).

Findings:

• A critical stenosis was confirmed in the mid-RCA, severely limiting blood flow.
• Distal occlusion of the RCA was observed, indicating a complete blockage beyond the primary lesion.
• These findings are consistent with an acute thrombotic event superimposed on significant atherosclerotic disease.

Implications:

• Prompt revascularization strategies may be necessary to restore blood flow to the myocardium.
• Aggressive medical management of diabetes and hypertension is crucial for secondary prevention.
• Understanding the angiographic characteristics of RCA lesions in NSTEMI patients informs therapeutic decisions.
