Description	We revisit the mechanism of neutrinoless double beta (0νββ) decay mediated by the exchange with the heavy Majorana neutrino N of arbitrary mass <i>m</i><sub>N</sub>, slightly mixed ~<i>U</i><sub>eN</sub> with the electron neutrino ν<sub>e</sub>. By assuming the dominance of this mechanism, we update the well-known 0νββ-decay exclusion plot in the <i>m</i><sub>N</sub>-<i>U</i><sub>eN</sub> plane taking into account recent progress in the calculation of nuclear matrix elements within quasiparticle random phase approximation and improved experimental bounds on the 0νββ-decay half-life of <sup>76</sup>Ge and <sup>136</sup>Xe. We also consider the known formula approximating the <i>m</i><sub>N</sub> dependence of the 0νββ-decay nuclear matrix element in a simple explicit form. We analyze its accuracy and specify the corresponding parameters, allowing one to easily calculate the 0νββ-decay half-life for arbitrary <i>m</i><sub>N</sub> for all the experimentally interesting isotopes without resorting to real nuclear structure calculations.
