Summary
Heavily calcified coronary plaque can cause unexpected stent under-expansion during percutaneous coronary intervention. Shockwave coronary lithoplasty offers a successful treatment for this challenging scenario.
Area of Science:
- Interventional Cardiology
- Cardiovascular Research
Background:
- Calcified coronary plaque poses significant challenges in percutaneous coronary intervention (PCI).
- Stent under-expansion is a frequent complication associated with heavily calcified lesions.
Observation:
- Two cases presented with unexpected coronary stent under-expansion.
- The underlying cause was identified as heavily calcified plaque.
Findings:
- Successful treatment of stent under-expansion was achieved using shockwave coronary lithoplasty.
- This demonstrates the efficacy of lithoplasty in managing complex calcified lesions.
Implications:
- Shockwave coronary lithoplasty provides a viable solution for treating stent under-expansion caused by calcified plaque.
- This approach may improve PCI outcomes in patients with complex coronary artery disease.

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...

657
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...
