An 89-year-old woman with multiple comorbidities and cachexia was admitted to the hospital for refractory heart failure treatment. Echocardiogram revealed a hypertrophied left ventricle with a severe calcific aortic stenosis (pressure gradient, 60 mm Hg; mean gradient, 23 mm Hg; aortic valve area, 0.6 cm2; annulus, 20 mm) and a moderate mitral regurgitation. A percutaneous aortic balloon valvuloplasty as a bridge-to-decision strategy was proposed. Femoral pulses were absent, so we opted for a variant technique using both right and left radial access. Two Glidesheath Slender 6/7 Fr sheaths (Terumo) were placed in the radial arteries and a left venous subclavian access was used for temporary pacemaker (Figures 1A-1C). Coronary angiography and aortography were performed (Figures 1D-1F), and the baseline left ventricle to aorta peak-to-peak gradient was 55 mm Hg.
Two semicompliant CBP balloons (12-40 mm; Balt) were advanced respectively over extra-stiff guidewires at the level of the annulus and inflated at 6 atm using a kissing-balloon technique during rapid pacing without any balloons sliding, with a predicted effective balloon diameter of 20 mm (Figures 1G-1I). Two dilations were performed without complications with a final peak to peak gradient of 10 mm Hg. Electrocardiogram was unchanged from baseline, and no vascular complications occurred. The patient did well; after 1 week, she was discharged home and referred as a possible candidate of transcatheter aortic valve implantation.
