LV unloading was performed using a percutaneous transseptal left atrial cannulation via the femoral vein incorporated into the ECMO venous circuit. The early and conventional LV .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 (n = 22, trans . A well-controlled size of the atrial septal defect can be created with a specially designed percutaneous device available in different sizes and allowing permanent closure after use. 20, 21 Likewise, LV venting via atrial trans-septal cannulation has been reported, 22 while the hemodynamic effects of percutaneous venting using a cannula .sheath,6–8 transaortic pigtail LV drain,9 surgical LA/LV vent and trans-septal cannula incorporated into ECMO. 10,11 However, the experience with these is mostly limited to children. Some methods are complex and destructive. Older . trans-septal LA decompression with the Inoue balloon to date. Despite the small number of patients . This review discusses the current approaches to vent the LV during V-A ECMO, with a selection of 45 papers published between 1993 and 2016. . Trans-Septal Venting. The presence of a left-to-right shunt due to atrial communication (for example, as a result of atrial septal defects or patent foramen ovale) may positively influence the .Venoarterial Extracorporeal Membrane Oxygenation for Cardiogenic Sh RESULTS. No death related to the LV unloading procedure was detected. Reduction in pulmonary capillary wedge pressure was highest with the TALVV technique (17.2 ± 2.1 mmHg; P < 0.001) and was higher in the PBAS than in the IABP group; the difference was significant (9.6 ± 2.5 and 3.9 ± 1.3, respectively; P = 0.001).Reduction in . Venting strategies during venoarterial extracorporeal membrane oxygenation (VA-ECMO). a Active left atrial venting via percutaneously introduced left atrial venting cannula (transseptal approach), which is directly connected to the venous VA-ECMO line.b Active left atrial venting via left atrial venting cannula (transseptal .We evaluated the benefit of left ventricular (LV) unloading using a percutaneous transseptal left atrial (LA) drain catheter via femoral vein incorporated into the ECMO venous circuit. This single-center retrospective observational study analyzed clinical outcomes of the LA venting group (N = 62) wh . Afterload of the LV is an indirect measure of the mechanical forces imposed on the myocardium during systole. Cardiac mechanical load is often considered synonymous with LV wall stress, a continuous measure throughout the cardiac cycle that is proportional to intracavitary pressure of the LV and radius and inversely proportional to .

Cardiac mechanical load is often considered synonymous with LV wall stress, a continuous measure throughout the cardiac cycle that is proportional to intracavitary pressure of the LV and radius and inversely proportional to . A well-controlled size of the atrial septal defect can be created with a specially designed percutaneous device available in different sizes and allowing permanent closure after use. 20,21 Likewise, LV venting via atrial trans-septal cannulation has been reported, 22 while the hemodynamic effects of percutaneous venting using a cannula . Second, this procedure minimizes the risk of transseptal communication closure. Third, the size of the cannula can be tailored to each patient, so this procedure can be adjusted for use in smaller patients. . Brown KL, Cohen GA, Redington AN. Percutaneous left ventricular “vent” insertion for left heart decompression during .These include trans-septal puncture and insertion of left atrial drain; trans-septal balloon and blade septostomy, and percutaneous insertion of a pulmonary artery or retrograde trans-aortic catheter functioning as a vent . Trans-septal balloon and blade septostomy remains a common practice in the pediatric population, but is less commonly . However, with progressive RV failure, repositioning of the trans-septal inflow cannula into the right atrium can provide biventricular support with drainage of both the right and left heart. This necessitates the addition of an in-line oxygenator, converting the system to VA ECMO without the need for an attendant LV vent. Two strategies of mechanical LV unloading were compared: afterload reduction (IABP) and preload reduction (Impella pump, surgically implanted LV vent, catheter venting of the left atrium from the right upper pulmonary vein or via trans-septal catheters, atrial septostomy). 3.1. Left ventricle unloading and death outcome meta .

We implanted a 21-Fr TandemHeart Protek Solo trans-septal cannula into the left atrium using a trans-septal approach via the femoral vein. The cannula was connected to the venous line of the ECMO circuit. . In the case of an LV thrombus, however, this treatment is contraindicated. Surgical insertion of an LV vent is possible .trans-septal lv vent Venoarterial Extracorporeal Membrane Oxygenation for Cardiogenic ShAnother indication may include placement of transseptal left ventricular assist device systems. The distribution of procedures requiring TSP in our cohort is presented in Fig. ( 3 3 ) , indicating that the majority were performed for left-sided accessory pathways, with AF ablation coming next. Valve-in-valve (ViV) TMVR is one such therapeutic option that has emerged as a safe and reproducible alternative for patients with a degenerated bioprosthesis at high-risk for repeat surgical mitral valve replacement ( 3 ). The ring of a degenerated bioprosthesis serves as a reliable anchoring point for a transcatheter valve, thus .

Left ventricle (LV) venting (unloading) has favorable effects on myocardial remodeling and hemodynamics. The preferred approach at our institution is by adding left atrial drainage via trans-septal puncture, resulting in Bi-Atrial VV-A (BAVVA) ECMO. An advantage of BAVVA-ECMO is that it avoids the need for additional large bore arterial access.

Left thoracotomy, trans-apical insertion of a 19-21Fr cannula into LV; average venting flow 600–1800 ml/min (trans-apical LV Vent group); transfemoral insertion of a IABP (Maquet) into safe zone (IABP group); transvenous transseptal puncture and balloon dilatation (balloon septostomy group)

Similar in concept to atrial septostomy, LV decompression may also be achieved percutaneously via trans-septal placement of a LA cannula connected the venous circuit of VA-ECMO with flow regulated by a clamp if needed . Unlike an LV vent, implantation and explantation of a pVAD are percutaneous procedures. As noted above, blood flow from a . AFTERLOAD MISMATCHING during venoarterial extracorporeal membrane oxygenation (VA-ECMO) can result in left ventricular (LV) distention, which may increase patient mortality, morbidity, extracorporeal membrane oxygenation (ECMO) duration, and duration of mechanical ventilation.
