OBJECTIVES: In severe pulmonary hypertension, diastolic dysfunction of the left ventricle causes significant morbidity and mortality after lung transplantation, which may be successfully reversed using a protocol based on perioperative veno-arterial extracorporeal membrane oxygenation (ECMO) and early extubation. Here, we present echocardiographic data and mid-term outcomes. METHODS: The records of lung transplanted patients at our institution between May 2010 and January 2016 were retrospectively reviewed...

OBJECTIVES: Left ventricular assist device (LVAD) exchange is becoming a standard surgical procedure. The exchange procedure is an opportunity to upgrade patients to a new generation pump that offers advanced reduction of adverse events or longer battery hours. METHODS: We performed an analysis of 6 consecutive patients who underwent LVAD exchange to HeartMate 3 either from a HeartWare or HeartMate (HM) II device. Minimally invasive operations were performed through a lateral thoracotomy...

The mortality rate for respiratory failure resulting from obesity hypoventilation syndrome is high if it requires ventilator management. We describe a case of severe acute respiratory failure resulting from obesity hypoventilation syndrome (BMI, 60.2 kg/m(2)) successfully treated with venovenous extracorporeal membrane oxygenation (VV-ECMO). During ECMO management, a mucus plug was removed by bronchoscopy daily and 18 L of water was removed using diuretics, resulting in weight loss of 24 kg. The patient was weaned from ECMO on day 5, extubated on day 16, and discharged on day 21...

Complications due to pump thrombus remain the weak point of mechanical circulatory support (MCS), such as the use of a left ventricular assist device (LVAD) or extracorporeal membrane oxygenation, leading to poor outcomes. Hyperspectral imaging (HSI) is an effective imaging method using a hyperspectral (HS) camera, which comprises a spectrophotometer and a charge-coupled device camera to discriminate thrombus from whole blood. Animal experiments were conducted to analyze dynamic imaging of thrombus inside a prototype of a hydrodynamically levitated centrifugal blood pump using an HSI system...

Fulminant myocarditis is a highly mortal syndrome. Meanwhile, the clinical course in surviving patients is generally self-limiting. This is a rare case of fulminant myocarditis with prolonged lymphocytic infiltration after hemodynamic recovery. A 64-year-old man was diagnosed with fulminant myocarditis and required intensive care with veno-arterial extracorporeal membrane oxygenation. Left ventricular function gradually improved but complete atrioventricular block (CAVB) persisted. Follow-up endomyocardial biopsies (EMBs) showed prolonged active infiltration of lymphocytes along with (18)F-FDG uptake in (18)F-FDG PET/CT until about 70 days after the onset...

OBJECTIVES: Whereas left-sided congenital diaphragmatic hernias (L-CDH) have been extensively studied and their prognostic parameters delineated, right-sided hernias (R-CDH) have not. Published results remain inconclusive. The aim of this study is to evaluate if proven prognostic indicators of postnatal survival in the fetus with L-CDH apply to the fetus with R-CDH. METHODS: Retrospective single-center study of R-CDH fetuses with available prenatal studies assessed for fetal lung volume by means of ultrasound-measured observed versus expected (O/E) lung area to head circumference (LHR) and magnetic resonance-calculated O/E total lung volume (TLV) in a 12-year time period...

Short-term ventricular assist devices (ST-VAD) have been effective in treating patients with refractory cardiogenic shock. Membrane oxygenators (MO) can be added to the circuit for concomitant profound refractory hypoxia. This study reports outcomes of combined therapy in this portion of patients. This is a retrospective review of 166 patients who received an ST-biventricular assist device (BiVAD) or right ventricular assist device (RVAD) for cardiogenic shock between November 2007 and November 2014. An MO was added to the RVAD for profound hypoxia refractory to maximized ventilation...

BACKGROUND: Ex vivo lung perfusion (EVLP) was primarily developed for evaluation of impaired donor lungs. The good clinical results raise the question for its possible impact on lungs meeting standard criteria. Before application of EVLP on such lungs enters routine clinical practice, it must be demonstrated whether EVLP would affect or improve outcome when used in standard donor lungs. We performed a prospective randomized trial to investigate the role of EVLP in standard lung transplantation (Tx)...

Extracorporeal membrane oxygenation has been used clinically for more than 40 years. The technique provides respiratory and/or circulatory support via venovenous and veno-arterial configurations, respectively. We review the basic physiological principles of extracorporeal membrane oxygenation systems in venovenous extracorporeal membrane oxygenation. Clinical aspects including patient selection, equipment, setup, and specific patient management are outlined. Pros and cons of the use of extracorporeal membrane oxygenation in respiratory failure are discussed...

Thrombate III is a human plasma-derived antithrombin III (AT-III) often utilized in patients on extracorporeal membrane oxygenation (ECMO) with suspected AT-III-mediated heparin resistance. It is supplied as 500-U and 1000-U vials, costing US$4.66 per unit. Literature is limited in describing the clinical value of AT-III in relation to its high cost. The primary objective was to determine conditions of use and associated cost of potentially unnecessary utilization of AT-III at The Johns Hopkins Hospital. Secondary objectives included evaluating the effect of AT-III on anticoagulation parameters and the overall cost utilized and wasted on AT-III...

Six patients suffering from acute respiratory distress syndrome with the need for extracorporeal membrane oxygenation (ECMO) therapy in deep sedation were included. Isoflurane sedation with the AnaConDa system was initiated within 24 hours after initiation of ECMO therapy and resulted in a satisfactory sedation (Richmond Agitation-Sedation Scale -4 to -5). Despite deep sedation, spontaneous breathing was possible in 6 of 6 patients. We observed a reduced need for vasopressor therapy and improved lung function (PaO2, PaCO2, delta P, and tidal volume) during isoflurane sedation...

The usual indications for extra corporeal membrane oxygenation (ECMO) are for respiratory or cardiac failure. Although continuous renal replacement therapy (CRRT) is frequently used when patients are on ECMO, the need for CRRT as the primary indication for ECMO is rare. A case of a neonate placed onto veno-venous ECMO for the use of CRRT to treat hyperammonemia from propionic acidemia is presented.

Heparin-induced thrombocytopenia (HIT) is an immune reaction usually secondary to unfractionated heparin. Anticoagulation management is critical in patients while on extracorporeal membrane oxygenation (ECMO) to prevent thromboembolism and for the optimal functioning of the circuit. We identified five patients with respiratory failure at our hospital managed with ECMO in the last 2 years that were treated for HIT. A brief clinical course and their management are discussed. We also briefly review the literature for best evidence for management of such patients...

The use of transcatheter aortic valve replacement (TAVR) as an acute treatment in severe decompensated bioprosthetic aortic valve disease is not well documented. We describe herein a unique case in which valve-in-valve (ViV) TAVR was successfully used as both an emergency salvage therapy and a bridge to definitive fourth reoperative aortic valve replacement (AVR) in a young patient with cardiogenic shock secondary to bioprosthetic aortic valve stenosis who was dependent on veno-arterial extracorporeal membrane oxygenation (VA-ECMO)...

Cardiogenic shock in the context of acute ST-elevation myocardial infarction (STEMI) remains a challenge to manage and results in significant mortality and morbidity, cardiac arrest in this setting even more so. The increase in myocardial oxygen demand and consumption with the use of inotropes is recognised as increasing mortality. Alternatives include the intra-aortic balloon pump (IABP), which has yet to be shown to improve outcomes, and extracorporeal membrane oxygenation (ECMO), which requires super-specialised techniques not widely available...

Acute myocardial infarction (AMI) can progress to cardiogenic shock and mechanical complications. When extracorporeal membrane oxygenation (ECMO) is applied to a patient with AMI with cardiogenic shock and mechanical complications, left ventricular (LV) decompression is an important recovery factor because LV dilation increases myocardial wall stress and oxygen consumption. The authors present the case of a 72-year-old man with AMI and LV dilation who developed cardiogenic shock and papillary muscle rupture and who was treated successfully by ECMO with a left atrial venting...
