1. A kit for replacement of a defective heart valve, said kit comprising:
a medical device for facilitating replacement of a defective heart valve of a heart of a patient and a prosthetic valve adapted to be attached to the heart valve, said medical device comprising:
a helical structure comprising
a first loop-shaped element configured to be positioned on a first side of the heart valve oriented towards a cardiac chamber of the heart, and
a distal loop-shaped element having a diameter suited to be introduced in between heart muscle wall and chordae of the heart for circumflexing a plurality of chordae,
wherein the first loop-shaped element has a smaller diameter than the distal loop-shaped element, whereby the first loop-shaped element is arranged to reposition the chordae towards a center of the heart valve upon rotational insertion of the helical structure,
wherein the medical device comprises a connection interface for releasably attaching a delivery device at a proximal end thereof, and
wherein the prosthetic valve is arranged to be movable along the medical device into position for said attachment to the heart valve.
