A case report of recurrent acute myocardial infarction and cardiac arrest due to aortic dissection secondary to IgG4-related aortitis.

Occlusion of the right coronary artery is a relatively rare complication of type A aortic dissection and an example of type 2 myocardial infarction (MI) as well but when it occurs, it may have a fatal result for the patient. Aortic pseudoaneurysms are local type A dissections with a restricted extent in which the majority of the aortic wall has been breached and luminal blood is held in only by a thin rim of the remaining wall, mainly purely the adventitia. They typically occur from iatrogenic trauma by interventional procedures or previous cardiac surgery.

Atrial fibrillation in transcatheter aortic valve implantation patients: Incidence, outcome and predictors of new onset.

Background: There is controversial evidence if atrial fibrillation (AF) alters outcome after transcatheter aortic valve implantation (TAVI). TAVI itself may promote new-onset AF (NOAF).

Methods: We performed a single-center study including 398 consecutive patients undergoing TAVI.

Establishing a donation after cardiac death model in pigs.

Introduction: Due to the lack of human donors, several strategies have sought to expand the organ pool. Efforts to characterize donation after cardiac death (DCD) have included studies of cell viability, histological and immunohistochemical changes, and oxidative stress, which is known to negatively impact graft survival. A large animal model would be useful for these inquiries.

Establishing a brain-death donor model in pigs.

Introduction: An animal model that imitates human conditions might be useful not only to monitor pathomechanisms of brain death and biochemical cascades but also to investigate novel strategies to ameliorate organ quality and functionality after multiorgan donation.

Methods: Brain death was induced in 15 pigs by inserting a catheter into the intracranial space after trephination of the skull and augmenting intracranial pressure until brain stem herniation. Intracranial pressure was monitored continuously; after 60 minutes, brain death diagnostics were performed by a neurologist including electroencephalogram (EEG) and clinical examinations.

A 10min "no-touch" time - is it enough in DCD? A DCD animal study.

Donation after cardiac death (DCD) is under investigation because of the lack of human donor organs. Required times of cardiac arrest vary between 75s and 27min until the declaration of the patients' death worldwide. The aim of this study was to investigate brain death in pigs after different times of cardiac arrest with subsequent cardiopulmonary resuscitation (CPR) as a DCD paradigm.
