Objective: Spinal cord injury (SCI) with subsequent paraplegia and/or stroke after arch repair with frozen elephant trunk (FET) remain the most devastating complications. In this study, we aim to examine the impact of different cerebral perfusion strategies on the neurological outcome comparing bilateral antegrade cerebral perfusion (bACP) and trilateral antegrade cerebral perfusion (tACP).
Methods: Between 2009 and 2021, 88 patients underwent total arch replacement using a hybrid prosthesis in FET technique for acute (40.
Objectives: The aim of this study was to compare short- and longer-term outcomes of David (DV) versus Florida sleeve (FS) procedure in patients requiring valve-sparing aortic root replacement.
Methods: Between January 1996 and December 2020 285 patients received a DV procedure (median age 60 years; 26% females) and 57 patients underwent an FS procedure (median age 64 years; 19% females) in our department. Propensity score matching using patient characteristics led to 58 (DV) versus 57 (FS) patients.
Background: The aim of this study was to evaluate the longer-term results of bicuspid aortic valve (BAV) repair with or without aortic root replacement.
Methods: From 1999 to 2017, 142 patients with or without aortic root dilatation who underwent repair of a regurgitant BAV were included in the study. Ninety-four patients underwent isolated BAV repair (Group 1; median age 43 years) and 48 patients underwent valve-sparing aortic root replacement plus BAV repair (aortic valve reimplantation-Group 2; median age 48 years).
Background: Aortic valve repair (AVR) is an attractive alternative to valve replacement for the treatment of aortic valve insufficiency. Here we report on the midterm outcomes after AVR for aortic valve insufficiency with an emphasis on durability of repair.
Methods: Between 1996 and 2017, 560 consecutive patients (mean age, 57 ± 16 years) underwent various AVR procedures on tricuspid (n = 415, 74%) and bicuspid (n = 145, 26%) aortic valves.
Background: The lower patency rate of vein grafts (VG) in comparison to arterial grafts may be related to vein valves, which favor turbulences and thrombosis that lead to graft failure. The aim of this study was to determine the outcome of patients with valvulotomized VG after coronary artery bypass grafting (CABG) procedure.
Methods: From 2007 to 2014, 233 patients with a mean age of 67 ± 9 years had CABG or combined CABG and valve procedures.
Background: Many techniques for repair of bicuspid aortic valves have been described and long-term results differ considerably. The current study evaluates our institutional results using the pericardial patch augmentation technique with the aim of increasing coaptation height.
Methods: From November 2002 through April 2015, 103 consecutive patients underwent aortic valve repair using pericardial patch augmentation for incompetent bicuspid aortic valve.
Objectives: For adult patients <60 years with aortic valve disease, the Ross procedure is an attractive alternative to a prosthetic aortic valve. The Ross procedure enables surgeons to achieve a haemodynamically ideal aortic valve replacement. A potential drawback may be long-term durability, which varies considerably between series.

Methods: From 1991 to 2013, the David technique was performed in 249 consecutive patients in our department. The patient mean age was 58 ± 14 years; 71 (29%) were female and 178 (71%) male.
