Insights

A perfusion balloon effectively treated ST-segment elevated myocardial infarction (STEMI) from very late stent thrombosis (VLST). This method maintained blood flow, allowing prolonged dilation to optimize vessel expansion without needing extra stents.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Research

Background:

  • Management strategies for ST-segment elevated myocardial infarction (STEMI) due to very late stent thrombosis (VLST) remain undefined.
  • Very late stent thrombosis (VLST) is a serious complication following percutaneous coronary intervention.

Observation:

  • This case series describes the successful revascularization of STEMI caused by VLST using a perfusion balloon.
  • The perfusion balloon (Ryusei: Kaneka Medix Corporation, Osaka, Japan) allows for sustained blood flow during prolonged balloon inflation.

Findings:

  • Extended inflation times with the perfusion balloon facilitated optimal lesion expansion.
  • This approach potentially prevents acute recoil and obviates the need for additional stenting.

Implications:

  • The use of a perfusion balloon presents a viable treatment option for STEMI secondary to VLST.
  • This technique may improve outcomes in patients experiencing this challenging clinical scenario.

Peripheral 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...

Pulmonary 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...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
