Summary
Intravascular lithotripsy (IVL) can fracture coronary calcifications but may rarely cause side branch (SB) occlusion. This case highlights the importance of pre-procedural assessment and protective wiring in high-risk lesions to prevent this complication.
Area of Science:
- Interventional Cardiology
- Cardiovascular Imaging
- Medical Device Technology
Background:
- Intravascular lithotripsy (IVL) is used to treat complex coronary artery calcifications.
- Side branch (SB) occlusion is a rare but serious complication following IVL.
- Optical coherence tomography (OCT) is crucial for assessing calcification and procedural outcomes.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
