Background: Medical devices such as implant delivery systems are commonly used during minimally invasive procedures in the cardiovascular system. These devices often have lubricious polymer coatings to reduce friction between the device and blood vessels but coatings may separate and potentially cause serious injuries to patients.
Methods: Lubricious coated eSheaths for transcatheter heart valve implantation were assessed for luminal integrity at the proximal, medial and distal part.
Current guidelines favor the radial approach for coronary angiography. Therefore, specialty radial diagnostic catheters were designed to engage both coronary arteries with a single device. However, it is unclear if single catheters are superior to conventional catheters.

However, the labeling of 14 F and 16 F eSheaths denote the inner nominal diameter. Exact changes of the clinically relevant outer diameters during usage are not available.

Investigation: The advantages and pitfalls of an interventional transfemoral approach, a transapical extraction of the dislocated prosthesis or the conversion to open heart surgery have to be balanced depending on the overall situation and the specific characteristics of the patient.
Diagnosis: A transfemoral approach would be the first choice for most TAVI implanters.
