Abstract
BACKGROUND
With the development of percutaneous coronary intervention (PCI), the number of interventional procedures without implantation, such as bioresorbable stents (BRS) and drug-coated balloons, has increased annually. Metal drug-eluting stent unloading is one of the most common clinical complications. Comparatively, BRS detachment is more concealed and harmful, but has yet to be reported in clinical research. In this study, we report a case of BRS unloading and successful rescue.
CASE SUMMARY
This is a case of a 59-year-old male with the following medical history: “Type 2 diabetes mellitus” for 2 years, maintained with metformin extended-release tablets, 1 g PO BID; “hypertension” for 20 years, with long-term use of metoprolol sustained-release tablets, 47.5 mg PO QD; “hyperlipidemia” for 20 years, without regular medication. He was admitted to the emergency department of our hospital due to intermittent chest pain lasting 18 hours, on February 20, 2022 at 15: 35. Electrocardiogram results showed sinus rhythm, ST-segment elevation in leads I and avL, and poor R-wave progression in leads V1–3. High-sensitivity troponin I level was 4.59 ng/mL, indicating an acute high lateral wall myocardial infarction. The patient’s family requested treatment with BRS, without implantation. During PCI, the BRS became unloaded but was successfully rescued. The patient was followed up for 2 years; he had no episodes of angina pectoris and was in generally good condition.
CONCLUSION
We describe a case of a 59-year-old male experienced BRS unloading and successful rescue. By analyzing images, the causes of BRS unloading and the treatment plan are discussed to provide insights for BRS release operations. We discuss preventive measures for BRS unloading.
Core Tip: Percutaneous coronary intervention plays a vital role in the treatment of coronary artery diseases. Recently, considerable attention has been given to bioresorbable stents (BRS), which can relieve coronary artery occlusions and reduce vascular stenosis. BRS can be absorbed or degraded, which helps restore vascular endothelial function and normalize systolic and diastolic functions. However, reports of clinical cases of BRS-unloading have been limited. Here, we present a case of BRS unloading and successful rescue, providing a practical treatment plan for such clinical scenarios.
