\documentclass[12pt]{article}

\usepackage{pifont}

% txfonts
\DeclareSymbolFont{TXsymbolsC}{U}{txsyc}{m}{n}   
\SetSymbolFont{TXsymbolsC}{bold}{U}{txsyc}{bx}{n}
\DeclareFontSubstitution{U}{txsyc}{m}{n}
\DeclareMathSymbol{\varheartsuit}{\mathord}{TXsymbolsC}{114}

% arev
\DeclareSymbolFont{extraup}{U}{zavm}{m}{n}
\DeclareMathSymbol{\varheart}{\mathalpha}{extraup}{86} % heart

\begin{document}
\Huge
\ding{164} \ding{170} $\varheartsuit$ $\varheart$
\end{document}
