Nowadays, only a few data are available about left heart unloading in V-A ECMO support. Despite the well-known controversy, IABP remains widely used in combination with V-A ECMO. Percutaneous approaches utilizing unloading devices is becoming an increasingly used option. However, further studies are required to establish the optimal LV unloading method.

Neurologic complications in adult patients on venoarterial extracorporeal membrane oxygenation support are common and associated with poor survival. Further research should focus on better understanding and management of brain/extracorporeal membrane oxygenation interaction to avoid such catastrophic complications.

Approximately 7% of adults supported with veno-venous extracorporeal membrane oxygenation for respiratory failure had neurologic injury. Intracranial hemorrhage was the most frequent type, and survival for patients with neurologic injury was poor. Future investigations should evaluate anticoagulation management as well as brain/extracorporeal membrane oxygenation interaction to reduce these life-threatening events.

AimsWe present 5-year echocardiographic results of combined undersizing mitral ring annuloplasty (UMRA) and coronary artery bypass grafting (CABG) in chronic ischaemic mitral regurgitation (CIMR). Methods and resultsTwo hundred and fifty-one patients (aged 68.4 + 8.1, 62.5% male) undergoing combined CABG and UMRA in our Institution (Cardiac Surgery, Careggi Hospital, Florence, Italy) between September 2001 and March 2007 were prospectively enrolled in the study. Median follow up was 32.9 months [interquartile range (IQR) 17.5-51.6]. Fourteen patients with significant residual mitral regurgitation (MR) needing immediate intraoperative revision (n ¼ 3) or at discharge (n ¼ 11) were excluded from the study. Serial echocardiograms were performed in 220 survivors at baseline, discharge, and annually thereafter. Additionally, 17 patients died (2 early and 15 late deaths) and were also excluded from the study. MR remained stable at 1 year and re-increased at 3 years (P , 0.001) and 5 years (P , 0.001). Fiveyear actuarial survival was 83.2 + 4.4. Five-year freedom from re-operation for failed repair was 78.2 + 4.9%. Mean systolic and diastolic diameters decreased significantly at discharge (P ¼ 0.001 and P ¼ 0.01, respectively) and at early follow up (P ¼ 0.004 and P ¼ 0.02) but raised at 3 years (P , 0.001) and 5 years (P , 0.001). Systolic and diastolic sphericity indexes improved at discharge (P , 0.001) remained stable at 1 year but they re-increased at 3-year control (P ¼ 0.006 and P ¼ 0.03, respectively) with a late raise exceeding the pre-operative value (P , 0.001). Left ventricular reverse remodelling was observed in 44.2% of the study population with 10.3% of patients showing further left ventricular dilatation. At multivariable model, end-systolic volume 145 mL, systolic sphericity index 0.7, myocardial performance index 0.9, and wall motion score index 1.5 were predictors of recurrent MR. ConclusionOur findings emphasize the need for improved repair technique and better patient selection to identify patients with anticipated repair failure who could benefit more from valve replacement or other procedure directly addressing ventricular tethering.--

Acute fulminant myocarditis (AFM) may represent a life-threatening event, characterized by rapidly progressive cardiac compromise that ultimately leads to refractory cardiogenic shock or cardiac arrest. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides effective cardiocirculatory support in this circumstance, but few clinical series are available about early and long-term results. Data from a multicenter study group are reported which analyzed subjects affected by AFM and treated with VA-ECMO during a 5-year period
