Potential of transcatheter aortic valve replacement to improve post-procedure renal function.

Background: Baseline comorbidities including renal dysfunction are frequently found in patients treated with transcatheter aortic valve replacement (TAVR) and may increase the risks of acute kidney injury (AKI), although some of them may actually improve renal function. We aimed to evaluate the potential of TAVR to acutely improve post-procedure renal function.

Methods: This is a prospective single-center registry of consecutive patients with severe symptomatic aortic stenosis treated by transfemoral TAVR.

Left Main Compression by a Giant Aneurysm of the Left Sinus of Valsalva: An Extremely Rare Reason for Myocardial Infarction and Cardiogenic Shock.

Aneurysms of the sinus of Valsalva are very rare and mostly located in the right coronary sinus. They might course with dyspnea, fatigue, and acute coronary syndromes. We present herein an extremely rare case report of a 61-year-old woman diagnosed with external left main coronary compression by a giant aneurysm of the left sinus of Valsalva, which was successfully managed with percutaneous coronary intervention.

Four-year clinical follow-up of the first-in-man randomized comparison of a novel sirolimus eluting stent with abluminal biodegradable polymer and ultra-thin strut cobalt-chromium alloy: the INSPIRON-I trial.

Background: The Inspiron™ sirolimus-eluting stent (SES) is a low-dose, ultra-thin-strut cobalt-chromium stent abluminally coated with biodegradable polymers (BP). Previous results from the INSPIRON-I trial, a first-in-man study, have proven the efficacy of the novel stent in reducing neointimal proliferation. The present report aims at evaluating the long-term clinical outcomes of patients enrolled into the INSPIRON-I trial (Clinical Trials Gov.
