Journal ArticleDOI
The innominate vein as alternative venous access for complicated implantable cardioverter defibrillator revisions.
Ivan Aleksic,Eva Kottenberg-Assenmacher,Peter Kienbaum,Andras K. Szabo,Sebastian-Patrick Sommer,Heiner Wieneke,Cagatay Yildirim,Rainer Leyh +7 more
TL;DR: The venous complications of implantable cardioverter defibrillator systems may cause significant problems when the need for system revision or upgrades arises, and such revisions require venous access close to the site of the previous ICD implantation.
Journal Article
Heart transplantation with bicaval and pulmonary venous anastomoses. A hemodynamic analysis of the first 117 patients.
Carlos Blanche,Sharon Nessim,Adrian W. Quartel,Johanna J.M. Takkenberg,Ivan Aleksic,Mabelle H. Cohen,Lawrence S.C. Czer,Alfredo Trento +7 more
TL;DR: Orthotopic heart transplantation performed with bicaval and pulmonary venous anastomoses offers improved post-transplant hemodynamics, eliminates the need for permanent pacemaker, and has improved patient survival when compared with the standard biatrial technique.
Journal Article
Anterior ischemic optic neuropathy: a complication after extracorporal circulation.
TL;DR: Preoperative risk factors, operative data, cardiopulmonary-bypass, postoperative complications and clinical symptoms are discussed together with ophthalmologic findings in order to elucidate the pathophysiology of this process.
Journal ArticleDOI
Impact of levosimendan and ischaemia-reperfusion injury on myocardial subsarcolemmal mitochondrial respiratory chain, mitochondrial membrane potential, Ca2+ cycling and ATP synthesis.
Stefanie Sommer,Marcus Leistner,Ivan Aleksic,Christoph Schimmer,K. Alhussini,Peer Kanofsky,Rainer Leyh,Sebastian-Patrick Sommer +7 more
TL;DR: Myocardial functions were analysed in a retrograde Langendorff-model followed by the analysis of subsarcolemmal mitochondrial functions and LS limited RCF at complex IV and V with ΔΨm hypopolarization suggesting a specific Ca(2+)-induced mPTP-opening susceptibility.
Journal ArticleDOI
Superior vena cava stenosis after orthotopic heart transplantation: complication of an alternative surgical technique.
TL;DR: Superior vena cava stenosis presented as a postoperative complication of orthotopic heart transplantation in a patient in whom a new surgical technique was used and required surgical repair 1 month after transplantation.
