Aortic Valvuloplasty and Large-Bore Percutaneous Arterial Access

First published: 06 May 2022

Summary

Percutaneous balloon aortic valvuloplasty (BAV) is a minimally invasive structural intervention for management of symptomatic severe valvular AS which emerged in the 1980s, first used in children with congenital AS and subsequently in adults with bicuspid aortic valve disease, rheumatic heart disease, and calcific AS. In the absence of aortic valve replacement (AVR), symptomatic severe AS portends a high risk of mortality that has remained largely unchanged despite advances in medical therapy. Before the recent advent of transcatheter AVR (TAVR), only half of older adults with severe AS would ever visit a cardiothoracic surgeon, and fewer still would ultimately undergo AVR. This chapter provides a comprehensive reassessment of BAV and large-bore arterial access for adult patients with calcific AS in the era of TAVR. It discusses the optimal approach to large-bore arterial access and retrograde percutaneous transfemoral BAV, acknowledging that there exist inter-institutional and inter-operator differences in technique, preference, and style.
