Real-time three dimensional transesophageal echocardiography has an incremental value in delineation of paravalvular leakages

We have read with great interest the article entitled ‘The relation between location of paravalvular leakage and time to reoperation after mitral valve replacement: an observational study published in Anadolu Kardiyol Derg 2013 Sep 10. (1). The authors aimed to evaluate any potential link between location of paravalvular leakage (PVL) and time to reoperation in patients undergoing redo mitral valve surgery. Thanks to the authors for their contribution of the present study. On the other hand, we want to make essential criticisms about this study from different aspects.
