The Journal of cardiovascular surgery, Volume 60, Issue 1, 29 5 2018, Pages 111-118 Excessive leaflet tissue in mitral valve repair for isolated posterior leaflet prolapse-leaflet resection or shortening neochords? A propensity score adjusted comparison. Tomšič A, Hiemstra YL, van Brakel TJ, Versteegh MI, Ajmone Marsan N, Klautz RJ, Palmen M
Background: Chordal replacement techniques are progressively used to treat posterior mitral valve leaflet (PMVL) prolapse while leaflet resection remains commonly in use to address excessive leaflet tissue. For excessive tissue in height, shortening neochords can be used alternatively. Use of chordal replacement techniques has been suggested to result in lower diastolic transvalvular gradients, higher freedom from reoperation and improved left ventricular function. Methods: From 1/2005 to 12/201... Abstract

Interactive cardiovascular and thoracic surgery, Volume 26, Issue 4, 1 1 2018, Pages 559-565 Mitral valve repair in Barlow's disease with bileaflet prolapse: the effect of annular stabilization on functional mitral valve leaflet prolapse. Tomšic A, Hiemstra YL, Bissessar DD, van Brakel TJ, Versteegh MIM, Ajmone Marsan N, Klautz RJM, Palmen M
Objectives: Barlow's disease is the most severe form of degenerative mitral valve disease, commonly characterized by bileaflet prolapse. Abnormal mitral annular dynamics is typically present and results in functional prolapse of the mitral leaflets that may be addressed with annular stabilization alone. Methods: Between January 2001 and December 2015, 128 patients with Barlow's disease and bileaflet prolapse underwent valve repair. This included anterior mitral valve leaflet (AMVL) rep... Abstract
American journal of translational research, Volume 10, Issue 3, 15 3 2018, Pages 816-826 No indications for platelet activation in acute clinical myocardial or renal ischemia/reperfusion injury. Kortekaas KA, de Vries DK, Roest M, Reinders ME, van der Veer EP, Klautz RJ, de Groot PG, Schaapherder AF, Lindeman JH
The pathophysiology of ischemia/reperfusion (I/R) injury is complex and poorly understood. Animal studies imply platelet activation as an initiator of the inflammatory response upon reperfusion. However, it remains unclear whether and how these results translate to clinical I/R. This study evaluates putative platelet activation in the context of two forms of clinical I/R (heart valve surgery with aortic-cross clamping, n = 39 and kidney transplantation, n = 34). The technique of sequential selec... Abstract
