Aug 1 (Reuters) - Healthcare firm Heartflow said on

Friday it was targeting a valuation of up to $1.32 billion in

its initial public offering in the United States.

The Mountain View, California-based company, backed by

private investment firm Bain Capital, is aiming to raise as much

as $212.5 million by offering 12.5 million shares priced between

$15 and $17 apiece.

Heartflow's listing comes more than three years after its

previous attempt to go public through a blank-check merger fell

through.

J.P.Morgan, Morgan Stanley and Piper Sandler are the lead

underwriters for the offering.

Heartflow will list on the Nasdaq under the trading symbol

"HTFL".
