“…Another recent study that compared different types of self-expanding valves showed that the 49° greater horizontal aorta was a modifying factor in the association between the type of self-expanding valve and the success of the device ( 2 ). There are case reports of valve-in-valve TAVR with complex anatomy, such as a horizontal aorta and an aortic aneurysm, that used a snare catheter to obtain satisfactory results ( 3 , 4 , 5 ). Therefore, we concluded that the snare catheter technique could be used in cases with complex aortic anatomy with aortic root angulations 48°.…”

The presence of a horizontal aorta in patients treated with transcatheter aortic valve replacement increases the difficulty of the procedure. We present 5 cases with aortic stenosis with a horizontal aorta who underwent transcatheter aortic valve replacement using a self-expanding prostheses, with the objective of describing the techniques used and obtaining success with a snare catheter. ( Level of Difficulty: Intermediate. )
