Mechanical Circulatory Assistance

The University of Wisconsin group analyzed the etiology, costs, and effect on survival of unplanned readmissions after LVAD surgery.  At a median follow-up of 11 months, 68 of the 103 patients (66%) were readmitted.  The top 3 causes of readmission were GI bleeding, driveline infection, and stroke.

The Mayo Clinic reviewed its series using VA ECMO for postcardiotomy support in patients older than the age of 70 years.  Not surprisingly, only a quarter of patients were able to be discharged alive.

The authors retrospectively analyzed the causes of death and their temporal relationship to surgery for close to 500 patients undergoing LVAD implantation at their institutions.

Filmed at the 2015 STS Annual Meeting in San Diego, Michael Bolanos and Mark Slaughter discuss topics in mechanical circulatory support and heart transplantation.

This concensus statement reviews the unique physiology, insertion techniques, and clinical indications for use of percutaneous mechanical circulatory support devices.  As the options for management of different etiologies of heart failure in adult and pediatric populations expand, understanding the advantages of specific devices is vital.

The authors retrospectively analyze outcomes for patients placed on ECMO for cardiogenic shock, and separately analyze the patients depending on whether the ECMO support was for isolated acute cardiogenic shock or for acute-upon-chronic cardiogenic shock.

The Columbia University group performed this retrospective review of femoral VA ECMO at their institution from 2007-2013, and analyzed short-term outcomes based on the size of the arterial cannula.
February 5, 2015
Extracorporeal membrane oxygenation (EMCO) offers a therapeutic option for moribund patients of all ages with acute pumonary or cardiac failure.  The authors present a retrospective analysis of the largest single institution experience with ECMO support, and present their perspective on the evolving use of ECMO supported by four decades of clinical r

This study from the University of Texas Southwestern sought to analyze the effects of mechanical unloading during prolonged LVAD support on mitochondrial mass, DNA damage response (DDR), and cardiomyocyte proliferation.  Ten matched human samples of LV myocardium were analyzed before and after mechanical circulatory support.
January 17, 2015
The authors perform a meta-analysis of the limited studies available on the utility of tricuspid valve surgery in patients with significant TR at the time of LVAD implantation.  No RCTs are available on this issue; however, six observational studies were analyzed by the group.
