Summary
Late stent thrombosis, a rare but serious complication, can cause heart attack or death. Proper dual antiplatelet therapy and technically correct Percutaneous Coronary Intervention (PCI) are crucial for prevention.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Late stent thrombosis is a severe complication following stent implantation, potentially leading to acute myocardial infarction or death.
- This case report details a patient experiencing recurrent myocardial infarction due to late stent thrombosis in previously implanted bare metal stents.
Observation:
- A 43-year-old male presented with acute ST-elevation myocardial infarction and right ventricular infarction, 18 months after initial Percutaneous Coronary Intervention (PCI) with two bare metal stents.
- Coronarography revealed right coronary artery occlusion at the site of previous stents, with thrombi identified in the stented segments and branches.
- The patient underwent repeat PCI, including guidewire recanalization, thrombus removal, and GP IIb/IIIa antagonist therapy.
Findings:
- Successful recanalization and treatment of thrombi resulted in good anterograde flow after repeat PCI.
- The patient's condition improved post-intervention, with minimal residual artery opacification defects.
Implications:
- This case underscores the critical importance of appropriate dual antiplatelet therapy post-PCI to mitigate the risk of late stent thrombosis.
- Ensuring technically sound PCI procedures, including correct stent sizing and expansion, is vital for long-term stent patency and patient outcomes.

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...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:27Peripheral Artery Disease III: Interprofessional Care
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...
01:23Peripheral Artery Disease V: Postoperative Nursing Management
During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:29Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:20Venous 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...
