A mitral valve repair update: simple, intuitive and physiological techniques, using running sutures (part I).

Today's mitral valve techniques are pluralistic, and the result of variable contributions over decades. However, they are often associated with subjectivity, and inter-surgeon variability, as well as differing outcomes. Here, we propose a set of conceptual techniques, which aim to simplify and standardize mitral valve repair, of which some we have already verified in practice.
