Balloon aortic valvuloplasty in high risk aortic stenosis patients with left ventricular ejection fractions <20%.

Objectives: To determine outcomes following balloon aortic valvuloplasty (BAV) in aortic stenosis (AS) patients with a left ventricular ejection fraction (LVEF) <20%.

Background: Severe AS patients with a LVEF <20% are excluded from United States (U.S.

Comparison of outcomes in high-risk patients>70 years of age with aortic valvuloplasty and percutaneous coronary intervention versus aortic valvuloplasty alone.

The goal of this study was to compare outcomes of combined balloon aortic valvuloplasty (BAV) plus percutaneous coronary intervention (PCI) with BAV alone in a surgically high risk, older (>70 years) population with both aortic stenosis (AS) and coronary artery disease (CAD). The medical records, coronary angiograms, and procedural reports of 100 consecutive patients who underwent BAV and coronary angiography at our institution from July 2003 to November 2006 were reviewed. Seventeen patients (mean age 86.

Feasibility of transcatheter intervention for severe aortic stenosis in patients >or=90 years of age: aortic valvuloplasty revisited.

Objectives: The goals of this study were to determine the feasibility, safety, and early outcomes of balloon aortic valvuloplasty (BAV) for severe aortic stenosis in a nonagenarian population.

Background: This very elderly population is expanding rapidly, has a high incidence of aortic stenosis, and uncommonly undergoes surgical aortic valve replacement. These patients may best be treated with a transcatheter approach due to comorbidities, surgical risk, and personal preference.

Radiation following percutaneous balloon aortic valvuloplasty to prevent restenosis (RADAR pilot trial).

Objectives: We wished to determine the feasibility and early safety of external beam radiation therapy (EBRT) used following balloon aortic valvuloplasty (BAV) to prevent restenosis.

Background: BAV for calcific aortic stenosis (AS) has been largely abandoned because of high restenosis rates, i.e.

Successful rotational atherectomy in the setting of extensive coronary dissection: a case of failed balloon angioplasty in a nondilatable calcified lesion complicated by balloon rupture and extensive dissection.

We describe a case of rotational atherectomy (RA) used in the setting of extensive coronary dissection. Unsuccessful predilitation of a heavily calcified proximal LAD stenosis resulted in balloon rupture, which produced occlusive dissection extending into the mid LAD. Limited options for this patient required that we perform RA to permit stent delivery and deployment and avoid anterior myocardial infarction.
