Complete atrioventricular block improved by balloon aortic valvuloplasty for severe aortic stenosis: Usefulness of sheathless technique in the retrograde approach

An 86-year-old man was admitted to our hospital for treatment of congestive heart failure with severe aortic stenosis and advanced atrioventricular (AV) block. Despite pharmacological therapy, he developed complete AV block and resultant acute pulmonary edema requiring temporary pacing and tracheal intubation. We urgently performed retrograde balloon aortic valvuloplasty (BAV) with a sheathless technique. The AV block disappeared soon after the procedure; this was probably attributable to the correction of relative myocardial ischemia, obtained by BAV. Thus, he successfully recovered from a critical condition.
