Abstract: Venoarterial extracorporeal membrane oxygenation (VA ECMO) is an established method of short-term mechanical support for patients in cardiogenic shock, but can create left ventricular (LV) distension. This .
Peripheral cannulation for VA-ECMO results in retrograde flow to the proximal aorta and substantial increase in left ventricular (LV) afterload, often leading to increased LV end-diastolic pressure and decreased .
Left ventricular (LV) unloading is a crucial point in the management of patients with severe LV dysfunction supported by extracorporeal membrane oxygenation (ECMO). Indeed, .
In 2017, Tepper et al. evaluated 45 VA-ECMO runs with concomitant LV venting using Impella (n = 23, Impella 2.5, CP, or 5.0) or surgically implanted LV vent . Venting the Left Ventricle Rationale of LV Venting. LV overload caused by peripheral VA-ECMO is a crucial concern for LV recovery. The detrimental effect of retrograde flow in the aorta that might lead to LV dilatation, increased left atrial pressure, and pulmonary edema is prominent.
One such debate relates to the need for and the optimal timing and type of a left ventricular (LV) venting strategy to counteract the potential overloading effects on the left ventricle that can occur during VA ECMO support. Several LV unloading strategies are available and recent advances have made them easier to deploy and use. 1, 2 However .
VA-ECMO may increase LV filling pressures leading to pulmonary edema. LV venting refers to techniques or methods that reduce LV filling pressures. LV unloading refers to any intervention that reduces .lv venting ecmo Lv vent procedure PDF VA-ECMO may increase LV filling pressures leading to pulmonary edema. LV venting refers to techniques or methods that reduce LV filling pressures. LV unloading refers to any intervention that reduces .
Indirect and Direct LV Venting During VA ECMO. Indirect LV venting during VA ECMO via atrial septostomy yielded an immediate and substantial LV unloading effect, but sizing of the defect can be critical because too much unloading may result in a nonejecting LV (Figure Figure7 7 and Table Table1 1 (Row 11–14)). Indirect pulmonary .
However, studies generally conclude that earlier LA decompression may result from a rapid weaning process and reduced complication risks related to prolonged VA-ECMO support. LV decompression can be successfully provided via various percutaneous methods, such as placement of IABP , transaortic LV venting [13, 14], . Alternatively, it has been proposed to anticipate temporary LV assist-device implantation upon initiation of VA ECMO, including adequate LV venting. 66,69 In this sense, it can be considered to use a large-sized LV apical vent with a minimum of a 32-F drainage cannula. Venous drainage of the VA ECMO circuit can be accomplished by .Peripheral cannulation for VA-ECMO results in retrograde flow to the proximal aorta and substantial increase in left ventricular (LV) afterload, often leading to increased LV end-diastolic pressure and decreased stroke volume. 1 This phenomenon of LV distention can result in pulmonary edema, thrombus formation in the left heart due to stasis, and . Rao and colleagues outline 5 considerations that should be made before offering VA-ECMO to a patient: (I) the indication, (II) the cannulation strategy, (III) LV distension/venting strategy, (IV) distal limb ischemia/perfusion strategy, and (V) exit strategy. 29 Indications for initiation of VA-ECMO are listed in Box 3. VAV-ECMO may even combine the advantages of venoarterial and venovenous ECMO therapy providing potent respiratory and circulatory support at the same time. 3 Another easy and low-cost option might be the insertion of a pigtail catheter (7 or 8 Fr) into the LV and connection of the pigtail catheter to the venous ECMO cannula which . In conclusion, the present study offers a unique opportunity to ponder the current knowledge on mechanical LV unloading/venting during VA-ECMO and suggests that—also in this setting—an individualized approach privileging assessment of CS aetiology, of pre-existing chronic haemodynamic adaptations, of the interaction of the .
Nevertheless, it is increasingly common to utilize one of the “LV venting” strategies, such as an IABP or Impella, despite unclear universal benefit . The device choice is often dependent of the center's experience and the benefit of upgrading from one strategy to another remains unexplored.

The device choice is often dependent of the center's experience and the benefit of upgrading from one strategy to another remains unexplored. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory .LV distension in patients with VA-ECMO can be safely and effectively treated by the percutaneous placement of a venting cannula in the pulmonary artery trunk. More data are required to confirm the safety and . The rate of venting in our VA ECMO population consisting of more than 600 patients is less than 2%. The concomitant use of an intraaortic balloon pump (IABP) with ECMO as the easiest method to decompress the left ventricle is not part of our protocol, neither is the use of an Impella device. . The low rate of LV venting in our population is . In one study, Centofanti et al. described the combination of VA ECMO and trans-apical LV venting through a left mini-thoracotomy and connected to the venous drainage line of ECMO ; in all patients, hemodynamics improved, recovery of heart function was observed in 46% of cases and 30-day mortality was 38%. These procedures require .
What are the granular aspects of management that should be included in trial design for VA-ECMO and LV venting? Figure 11. Flow chart on VA-ECMO management according to etiology. Advertisement. Advertisement. Acknowledgments. This may be ameliorated with the addition of ventricular mechanical unloading, an LV vent, of which there are several varieties, including surgical vents in the LV apex, pulmonary artery vents, and percutaneous transvalvular vents. . A randomized trial to evaluate the safety and effectiveness of percutaneous LV venting in peripheral . Indirect LV venting during VA ECMO via atrial septostomy yielded an immediate and substantial LV unloading effect, but sizing of the defect can be critical because too much unloading may result in a nonejecting LV (Figure 7 and Table 1 (Row 11–14)). Indirect pulmonary artery venting, or direct transaortic LV venting, as well as . In adult patients requiring peripheral VA-ECMO support, the use of an LV MU strategy compared to no MU was associated with lower in-hospital and on-support mortality. Complication rates of cannula site bleeding and hemolysis were higher with MU. MU with IABP compared to pVAD had similar in-hospital mortality but lower complication .At our institution (Montefiore Medical Center, the Bronx, New York, USA), an acute shock ECMO phenotype protocol is used to categorize which patients may benefit from venting of the LV with an intra-aortic balloon pump (IABP) or percutaneous ventricular assist device (pVAD) during ECMO support . This assessment allows development of a tailored . The LV vent was inserted during ECMO cannulation, and repeat echocardiography post venting showed a reduction in LV size compared to patients who did not undergo decompression . Patients with a vent also had significantly higher 30-day survival (55% versus 25%, P=0.034), though there was no difference in mortality at 12 .lv venting ecmo 2. Is venting the same as unloading in the case of ECMO? No. Venting is not the same as unloading. Venting uses passive strategies to treat ventricular distension including techniques such as atrial septostomy. These passive techniques differ significantly from active volume and pressure unloading.Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is widely used in cardiogenic shock. It provides systemic perfusion, but left ventricular (LV) unloading is suboptimal. Using a closed-loop, real-time computer model of the human cardiovascular system, cardiogenic shock supported by periphe . When more unloading is required, Impella should be added to V-A ECMO, as increasingly reported recently [70, 71].Of all other options, Impella appears to offer the largest and most direct form of LV decompression, while providing additional active blood flow to systemic circulation at the same time .Indications for LV venting are generally . Objectives: Patients in cardiogenic shock supported with venoarterial extracorporeal membrane oxygenation (VA-ECMO) may experience severe complications from reduced left ventricular (LV) unloading and increased cardiac afterload. These effects are usually modified by adding a percutaneous direct Impella vent or surgical LV vent . Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is used as mechanical circulatory support in critical heart failure and circulatory collapse, including after cardiac surgery with cardiopulmonary bypass (CPB) and cardioplegic arrest. 1 In a poorly contracting left ventricle (LV) an increase in afterload generated by the ECMO circuit .
In case of not recommended usage of direct LV apical venting (e.g., LV apical thrombi, recent antero-apical AMI, acute myocarditis and graft failure after heart transplantation), we institutionally prefer the adoption of V-A peripheral ECMO support associated with a PA drainage, since it enables the rapid onset of extracorporeal life .
Cardiogenic shock and cardiac arrest contribute pre-dominantly to mortality in acute cardiovascular care. Here, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has emerged as an established therapeutic option for patients suffering from these life-threatening entities. VA-ECMO provides t .
