TAVR Workflow · Bicuspid Sizing

A complete algorithm suite for bicuspid anatomy

A dedicated bicuspid pathway with device-matched risk algorithms and a specialized Type 0 workflow. The ABC root-rupture algorithm is peer-reviewed in Circulation: Cardiovascular Interventions (2026).

In QuanTAVI Type 0 workflow

Bicuspid sizing, made objective

QuanTAVI automates the full bicuspid measurement set from CT and applies the right sizing algorithm for each device — with a specialized Type 0 pathway for true two-leaflet anatomy.

Automated bicuspid measurements from CT
Device-matched sizing across every valve platform
Specialized Type 0 workflow with calcium analysis

The Suite

Every device, the right algorithm

Balloon-expandable · SAPIEN 3 / MyVal

ABC

Peer-reviewed root-rupture risk model with calcium-aware sizing and safety stops.

Self-expanding · Evolut / Navitor

LIRA

Raphe-level fit check that guides self-expanding valve sizing.

Self-expanding · Evolut / Navitor

CASPER

Calcium- and raphe-driven sizing adjustment for self-expanding valves.

Root geometry

BAVARD

Classifies the root — tubular, flared, or tapered — to inform the seal strategy.

Specialized workflow

Type 0 bicuspid

A dedicated pathway for true two-leaflet anatomy without a raphe — two-point cusp definition and per-leaflet calcium logic.

Real Output

One case, every platform

The same bicuspid anatomy, sized for both balloon- and self-expanding valves — device-specific decisions, side by side.
