The Tikz calc library is your friend here---the following should achieve 
what you want to achieve:

% in preamble,
\usepackage{tikz}
\usetikzlibrary{calc}

% in your tikzpicture

\draw (a.est) -- ($(b.west) + (0,1)$);

You can do all manner of relative tweaking if you wrap the calculation 
with ($ ... $)
