Abstract: Aspects of the disclosure relate to systems, delivery devices and method for transcatheter delivery of a cardiac implant such as a prosthetic heart valve. Systems of the disclosure are configured to support the delivery device in an inferior vena cava and/or superior vena cava to reduce the potential for damage to heart tissue during delivery of the implant as the delivery device is articulated through the vasculature.
