We conclude that patients with highly impaired left ventricular function and ischemic mitral insufficiency are at too great a risk for either valve reconstruction or replacement. Cardiac transplantation should be considered for this patient group. However, patients with ischemic mitral insufficiency and moderately impaired left ventricular function can undergo valve reconstruction or replacement with an acceptable prognosis. The goal of mitral valve reconstruction should be reducing mitral valve insufficiency to at least grade I. If this is not achieved, the prognosis after repair is worse than after valve replacement, therefore, the surgeon should replace the valve without delay.

Inadvertent emergency anticoagulation in patients with acute type A aortic dissection (ATAAD) has been sparsely reported. There are case reports bringing this potential critical incident to attention, however, little is known about the number of undetected and unreported cases. We approach this issue based on a case report of inadvertent emergency anticoagulation in ATAAD and attempt to shed light on aspects that may have contributed to the critical incident: The challenge of distinguishing an ATAAD from an acute coronary syndrome (ACS) and the potential underestimation of incidents of ATAAD. We also discuss errors and biases in medical decision making, and provide suggestions that may help raise awareness of how ATAAD can be mimicking ACS in clinical practice.

Transcatheter aortic valve implantation (TAVI) has become an established treatment option for aortic valve stenosis in patients with a high risk for conventional surgical valve replacement. A well-known complication is the development of conduction abnormalities. In the case of a new third-degree atrioventricular block, the complication can be life-threatening and permanent pacing is needed. Often these patients have a venous sheath placed in the jugular vein for the perioperative period. We report a case of inadvertent dislodgement of a permanent pacemaker lead after removal of a preoperatively placed venous sheath in a TAVI patient.
