The MVP seems to combine the efficacy of AMPLATZER plug with the navigability of micro-coils,
being able to reach distal targets thanks to the microcatheter delivery; the vascular flow should stop immediately if the correct MVP caliper has been choosen,
since it is a partially PTFE covered device.
Based on the reported experience,
the main advantage is related to MVP3 and MVP5 models that can be adopted for distal embolization thanks to the precise release through 0.027″ microcatheter.
The pros of the MVP are: the device is able to easily navigate in tortuous and twisted vessels thanks to the Nitinol skeleton; MVP3 and MVP5 can be released through a 0.027″ microcatheter,
allowing distal embolization in small arteries; the detachable system permits to retract and repositioning
MVP multiple times.
The cons of the MVP are: visibility of only the distal and proximal radiopaque markers; need of a sufficient straight landing zone able to receive the unconstrained length of the MVP (12 mm for MVP3 and MVP5; 16 mm for MVP7) before releasing the device; need of precise measurement of the vessel to embolize to adopt the correct MVP size and avoid device migration and unsuccessful procedures.
