Zero-contrast IVUS-guided complex PCI in a patient with NSTE-ACS and severe renal impairment.
Catheter Cardiovasc Interv
May 2023
A 76-year-old male with severe comorbidities and multiple cardiovascular risk factors including stage IV chronic kidney disease presents with non-ST-elevation myocardial infarction. An ultra-low contrast invasive coronary angiography using the DyeVert system and iso-osmolar contrast agent revealed a multivessel disease with heavy calcifications involving the left main stem and its bifurcation requiring a complex percutaneous coronary intervention. Because of the high risk of contrast-induced acute kidney injury, a zero-contrast intervention was performed using intravascular ultrasound guidance and dedicated stenting techniques with optimal imaging, clinical, and renal outcomes.

- Percutaneous circulatory support is increasingly used in complicated coronary interventions, but large systems typically require access through the common femoral artery.
- A 64-year-old man with severe coronary artery disease and heart failure underwent successful coronary intervention using an IMPELLA 2.5L system, which was uniquely inserted through the left brachial artery due to his peripheral vascular disease.
- This case marks the first documented use of the brachial approach for the IMPELLA system in high-risk procedures, suggesting it could be a viable option when traditional access points are unavailable.
Background: Several progressively refined percutaneous devices for patent foramen ovale (PFO) closure have been recently developed. We describe our single-center experience with the new Gore septal occluder (GSO).
Methods: Between January 2012 and May 2013, all consecutive patients with a PFO and previous cerebral thromboembolic events underwent percutaneous closure with the GSO system.
Seventy-seven crude extracts from leaves and stem barks of 15 Gabonese plants used in traditional medicine were evaluated for their cytotoxic, antileishmanial and antifungal activities. Most of the extracts exhibited cytotoxic activities toward human monocytes, and most particularly the hydromethanolic 50% (v/v) fraction of Ganophyllum giganteum leaves (IC(50)=1.3 microg/ml) as well as the methanolic extracts of Polyalthia suaveolens, Dioscorea preussii, Augouardia letestui leaves and Cola lizae stem barks (IC(50)<5 microg/ml).
