“…This is somewhat similar to the principle of TandemHeart. 7 Hence, we considered that no action was required since perfusion improved and such a shunt may have been helpful. However, not repositioning the cannula may introduce risks such as pericardial tamponade, systemic embolism, and decreased membrane lung efficiency.…”

Ultra-high pre-membrane lung oxygen saturation in a patient on veno-arterial extracorporeal membrane oxygenation

A 55-year-old man who suffered from acute myocardial infarction complicated with cardiogenic shock was administered veno-arterial extracorporeal membrane oxygenation. Ultra-high pre-membrane lung oxygen saturation of 93% was observed. Transthoracic echocardiography revealed the presence of patent foramen ovale. The four-chamber view showed that the tip of the cannula was located in the patent foramen ovale, which resulted in a left-to-right shunt. Without adjusting the position of the drainage cannula, the patient was weaned from extracorporeal membrane oxygenation at 136 hours after initiation and survived to hospital discharge.

“…All patients were supported with an ECLS circuit that utilized the TandemHeart ventricular assist device (LivaNova, London, UK), a pediatric oxygenator (Maquet Quadrox iD, Getinge, Goteborg, Sweden), and a temperature regulator (MCH 1000-i, CardioQuip, College Station, TX, USA). 4 The circuit included post oxygenator gate clamps and a recirculation limb that incorporated a hemoconcentrator/filter (Sorin DHF 0.6, LivaNova) in order to permit lower flows to smaller patients. This recirculation limb effectively reduces the flow to the patient by diverting a portion of the set output from the ventricular assist device.…”

“…In 2016, our congenital heart center adopted an ECLS system that is unique in mechanical design, deployment, and management. The ECLS circuit is designed to utilize a modified continuous-flow ventricular assist device as pioneered by Monge et al [1][2][3][4] The logistic and management philosophy utilizes a model where the bedside intensive care unit nurse functions as the ECLS specialist.…”

Extracorporeal life support (ECLS) is an essential component of a modern congenital cardiac surgery program. The circuit components and bedside management team may, however, vary among institutions. Here, we evaluate our initial experience with a modified ventricular assist device—based ECLS circuit primarily managed by the bedside nurse. We hypothesize that our outcomes are comparable to Extracorporeal Life Support Organization (ELSO) registry data. All patients who received ECLS from January 1, 2016 to December 31, 2019 at a single institution were included. Primary outcomes were survival to ECLS decannulation and discharge or transfer. Secondary outcomes included complications from ECLS. Data were compared to available ELSO registry data. Thirty‐seven patients underwent 44 ECLS runs during the study period. Forty percent of patients had single ventricle physiology. Nearly 46% of patients received ECLS as part of extracorporeal cardiopulmonary resuscitation (eCPR). Survival to ECLS decannulation (68.2%) and survival to discharge or transfer (61.4%) did not differ from overall ELSO outcomes (69.7%, P = .870 and 50.7%, P = .136), as well as survival to discharge or transfer in a comparable cohort of ELSO centers (53.1%, P = .081). Patients with complications had a lower rate of survival to discharge or transfer but this did not reach statistical significance (47.7% vs. 75.0%, P = .455). Neurologic (50.0%), hemorrhagic (45.5%), and renal complications (31.8%) were most common in this cohort. A modified ventricular assist device‐based ECLS circuit with primary management by the bedside nurse can provide comparable support in a neonatal and pediatric cardiac surgery population. Cost analyses and further delineation of the complication profile are necessary for a complete characterization of this system.
