Summary
This case involves a high-risk percutaneous coronary intervention to treat stent restenosis in a patient with complex coronary artery disease. The procedure addresses an unexpanded stent lodged in critical coronary arteries, aiming to relieve severe angina.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- A 64-year-old female patient presented with crescendo angina pectoris.
- She had a history of coronary artery bypass surgery and angioplasty with an unexpanded stent entrapped in the circumflex coronary artery and left main.
- Surgical intervention was deemed very high risk.
Purpose of the Study:
- To describe the management of complex stent restenosis in a challenging anatomical location.
- To evaluate the feasibility of elective percutaneous coronary intervention (PCI) in a high-risk scenario.
Main Methods:
- The patient underwent an elective percutaneous coronary intervention.
- The procedure focused on addressing stent restenosis caused by an unexpanded stent in the circumflex coronary artery and left main.
Main Results:
- Percutaneous coronary intervention was successfully performed despite the procedural complexity.
- The intervention aimed to alleviate symptoms of crescendo angina pectoris.
Conclusions:
- Elective percutaneous coronary intervention can be a viable option for complex stent restenosis in high-risk patients.
- Careful planning and execution are crucial for managing unexpanded stent entrapment in critical coronary arteries.

1.9K
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...

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...

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...

813
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...

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...

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...
