Observational StudyEffective Dose of Landiolol, an Ultra-Short-Acting β-Blocker, to Decrease Heart Rate During On-Pump, Beating Coronary Artery Bypass Grafting.
Decreasing the heart rate (HR) using landiolol, an ultra-short-acting β-blocker, is helpful for completing a meticulous distal anastomosis during on-pump or off-pump, beating coronary artery bypass grafting (CABG) surgery. We determine the effectiveness of landiolol to decrease the HR because the most effective dose has not been established. ⋯ Landiolol maximally decreased HR just over 20% of the baseline HR. Hence, landiolol 25 μg/kg/min is likely a sufficient dose during LITA-LAD anastomosis during on-pump, beating CABG.

Venovenous Extracorporeal Membrane Oxygenation for Patients With Return of Spontaneous Circulation After Cardiac Arrest Owing to Acute Respiratory Distress Syndrome.
The primary objective of this study was to determine the survival to hospital discharge of patients who were treated with venovenous (VV) extracorporeal membrane oxygenation (ECMO) for respiratory failure after cardiac arrest. ⋯ VV ECMO may be an appropriate alternative to venoarterial ECMO in select patients with return of spontaneous circulation after cardiac arrest owing to profound respiratory failure.

Case ReportsRight Atrial Inversion Mimicking Right Atrial Mass in the Setting of Cardiac Tamponade.
A 44-year-old woman was transferred to the authors' institution in cardiogenic shock secondary to a presumed viral myocarditis and subsequently was placed on venoarterial extracorporeal membrane oxygenation. Transthoracic echocardiography revealed a large right atrial mass of unknown etiology and moderate pericardial effusion. ⋯ Intraoperative transesophageal echocardiography demonstrated cardiac tamponade with complete invagination of the right atrium. Surgical evacuation of the pericardial effusion reverted the right atrium, with no further evidence of the right atrial mass, and no mass was discovered after right atriotomy, indicating that the right atrial "mass" was likely the result of complete inversion of the right atrium in the setting of cardiac tamponade.
