Improvement in coronary microvascular dysfunction after transcatheter aortic valve implantation leading to positive fractional flow reserve and percutaneous coronary intervention: a case report
This case illustrates that transcatheter aortic valve implantation may unmask coronary ischaemia by restoring microvascular vasodilatory capacity in patients with coronary microvascular dysfunction. It also highlights the importance of reassessing coronary physiology in selected patients following transcatheter aortic valve implantation.
