What are the implications that two trials suggested a mortality benefit when the radial approach was used to access the arterial system during a STEMI?

Concomitant renal artery stenosis (RAS) aggravates coronary artery disease, but no reports have been published on the feasibility, safety and outcomes of concomitant percutaneous renal artery stenting in patients presenting with acute coronary syndrome (ACS) at high clinical risk of RAS. We conducted a retrospective study of 82 of these high-risk patients and found peripheral arterial disease to be the only predictive factor for RAS in multivariate analysis.

We studied the outcomes of 199 patients with multivessel coronary artery disease and STEMI complicated by shock who underwent PCI at the Cleveland Clinic between 01/01/2002-6/30/2010. We found that approximately 1 out of 4 of these patients were treated with multivessel PCI.

We conducted a study to evaluate the transcatheter paravalvular leak closure (TPVLC) aptitude to reduce manifestations of heart failure caused by aortic paravalvular leak (PVL) and found that heart failure caused by aortic PVL can be safely and efficiently treated with TPVLC using AVP II and III devices as occluders.

Acute ST elevation myocardial Infarction (STEMI) is associated with significant arrhythmia and cardiac arrest. QT prolongation can occur in the setting of ischemia or acute STEMI as a risk factor for arrhythmia. The goal of this study was to investigate QTc, QT dispersion (QTd) and T wave peak to end (TPE) times in this patient population and evaluate the effect of primary percutaneous coronary intervention (PCI) in STEMI patients on these indices.

An evaluation into predictors of recovery after balloon aortic valvuloplasty (BAV) among patients with aortic stenosis and depressed left ventricular ejection fraction (LVEF) was conducted among 151 consecutive patients (59 of whom had poor LVEF) treated in our institution by BAV.
