Mechanical circulatory assistance

March 27, 2016
Norepinephrine is often used to maintain the mean pressure during open heart surgery but it is said that it could constrict cerebral arteries, reducing cerebral blood flow. Is it true? The authors explored the association of Norepi doses and rSO2 measured using near-infrared spectroscopy.

Robert Bartlett, Emeritus Professor of Surgery at the University of Michigan Medical Center, Ann Arbor, Michigan, presents an informative talk on extracorporeal membrane oxygenation (ECMO).

As the Authors have stated: "maximal medical therapy can no longer be seen as a justifiable end‐point for refractory circulatory shock, at least in well‐resourced health settings." To frame their discussion on mechnical circulatory support (MCS) in the current era, they have provided a case vignette for options potentially available to the patient wi

This is a very interesting and provocative article that discusses Exracorporeal Cardiac Life Support (ECLS) as an adjunct to CPR. ECLS has gained in popularity with new tools and techniques, ECLS guidelines, protocols and better understanding of the importance of early initiation.

Outcomes of CABG for patients in cardiogenic shock after acute MI were evaluated using data from the STS Database.  The study group of nearly 5,500 patients comprised 1.5% of all CABG patients during the study period.  Operative mortality was 18.7%.  Mechanical circulatory support use was most common in patients with more risk factors or high clinica

Michael Acker of the University of Pennsylvania Health System, Philadelphia, gives an in-depth talk on the current state of temporary mechanical circulatory support practices in the United States.

The investigators report a novel technology to predict VAD thrombosis. This approach records and measures acustic signature characteristics. Using annalysis of spectral tracings the investigators suggest their exists an acoustic patern associated with thrombosis.

The paper evaluates de novo development of aortic insufficiency (AI) following implantation of continuous flow left ventricular assist (84 HeartMate II, 13 HeartWare, 2 VentrAssist). Preoperatively, 17 patients had mild AI, which did not change later.

The authors describe the tricks and traps of minimally invasive approach during VAD implantation, by associating mini anterior left thoracotomy in the fifth intercostal space with a mini anterior right thoracotomy in the second intercostal space, without the aid of CPB in paravertebral block regional analgesia combined with mild general anaesthesia.
