Zero-contrast IVUS-guided complex PCI in a patient with NSTE-ACS and severe renal impairment.

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.

Left brachial artery: one more way to percutaneous insertion of IMPELLA 2.5L circulatory support for high-risk percutaneous coronary intervention - a case report.

Background: Percutaneous circulatory support allows the performance of coronary interventions in ever more complex anatomic and clinical situations. The large-bore systems currently available need a suitable vascular calibre to be inserted restricting percutaneous access mainly to the common femoral artery.

Case Summary: We present the case of a 64-year-old man, admitted with an acute coronary syndrome and congestive heart failure, due to triple-vessel coronary artery disease with left main involvement and left ventricular dysfunction.

Clinical Performance of the New Gore Septal Occluder in Patent Foramen Ovale Closure: A Single-Center Experience.

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.
