Subacute groin complications related to ECMO cannulation are associated with longer hospitalizations
AbstractSubacute groin complications associated with extracorporeal membrane oxygenation (ECMO) cannulation are well recognized, yet their effects on clinical outcomes remain unknown. This single-center, retrospective study reviewed all patients receiving venoarterial ECMO from 01/2017 to 02/2020. Cohorts analyzed included transplanted patients (TPs) and non-transplanted patients (N-TPs) who did or did not develop ECMO-related subacute groin complications. Standard descriptive statistics were used for comparisons. Logistic regressions identified associated risk factors. Overall, 82/367 (22.3%) ECMO patients developed subac...

A case of severe respiratory failure due to interstitial pneumonia successfully bridged to lung transplantation from a brain-dead donor using 109-day veno-arterial extracorporeal membrane oxygenation
We present the case of a man in his thirties, diagnosed with interstitial pneumonia 6 years prior and registered for lung transplant 1 year prior due to disease progression despite treatment. Due to the patient’s worsening respiratory failure, he was transferred to our hospital for BTT by ECMO. Since long-term management was expected and pulmonary hypertension was present, veno- arterial (V-A) ECMO was conducted using the right atrial blood outflow via the right internal jugular vein and right axillary artery inflow via a vascular graft. After tracheostomy, he was managed as “Awake ECMO”. In addition, interprofess...

Osteocompatibility of Si3N4-coated carbon fiber-reinforced polyetheretherketone (CFRP) and hydroxyapatite-coated CFRP with antibiotics and antithrombotic drugs
In conclusion, the additional surface treatment of the HA-coated CFRP with VCM and PVP provided sufficient bone fixation and formation. (Source: Journal of Artificial Organs)

Interference of a ventricular assist device with magnetic navigation during insertion of Sherlock 3CG ™, a bedside peripherally inserted central catheter
AbstractRecently, the Sherlock 3CG ™ Tip Confirmation System, including a magnetic tracking system and an intracavitary electrocardiography guidance system, has been introduced for bedside peripherally inserted central catheter (PICC) insertion. Magnetic field sources interfere with the magnetic tracking system. Electromagnetic int erference of the ventricular assist device (VAD) has already been reported with various devices but not on Sherlock 3CG™. We assessed the availability of the magnetic tracking system in patients with and without a VAD during Sherlock 3CG™ insertion and evaluated the rate of optimal PICC ti...

Improvement of predicted hematocrit values after the initiation of cardiopulmonary bypass in cardiovascular surgery
This study aimed to clarify the limits of agreement (LOA) and bias of the prediction equations and investigate better the prediction equations. A retrospective study was performed on adult patients between April 2015 and December 2020. Study 1 included 158 patients, and Study 2 included 55 patients. The primary outcomes were the LOA and bias between the predicted and measured Hct values after the initiation of CPB, and two studies were conducted. In Study 1, total blood volume (TBV) was estimated, and the new blood volume index (BVI) was calculated. BVI was also evaluated for the overall value and gender differences. There...

COVID-19 ARDS in two patients with left ventricular assist device
AbstractCoronavirus disease 2019 affected millions of people and caused pneumonia, acute respiratory distress syndrome and increased mortality worldwide. Data from multicenter studies showed that concomitant chronic diseases are associated with severe coronavirus disease. Patients with left ventricular assist device (LVAD) support may also be vulnerable to the disease. Some symptoms of COVID-19 infection like dyspnea and fatigue can overlap with heart failure or LVAD dysfunction. Careful evaluation should be made to diagnose and treat these patients. In these two cases with COVID-19, here we presented the first two patient...

Risk factors of gynecological bleeding in female patients with left-ventricular assist device
AbstractWomen with implantable left-ventricular assist devices (LVADs) experience gynecological bleeding (GYN-bleeding). However, a few studies have investigated female-specific problems. Therefore, this study aimed to identify the risk factors for adverse GYN-bleeding after LVAD implantation. We retrospectively analyzed 59 women (mean age: 41 ± 15 years) with long-term implantable LVAD support (≥ 6 months) at our institution between 2005 and 2018. The history of GYN-bleeding before implantation was defined as abnormal utero-ovarian bleeding, excessive menstruation, uterine fibroids, and endometrial lesions. GY...

Impact of prosthesis-patient mismatch on late outcomes after bioprosthetic mitral valve replacement for mitral regurgitation
AbstractNegative impact of prosthesis-patient mismatch on long-term survival after valve replacement has been reported. However, the effect of prosthesis-patient mismatch after bioprosthetic mitral valve replacement has not yet been well examined. The purpose of this study was to investigate the effect of prosthesis-patient mismatch on late outcomes after bioprosthetic mitral valve replacement for mitral regurgitation. A total of 181 patients underwent bioprosthetic mitral valve replacement between April 2008 and December 2016. After excluding patients with mitral stenosis and those with incomplete data, 128 patients were ...

Coronary artery bypass grafting under sole Impella 5.0 support for patients with severely depressed left ventricular function
In this study, we would like to share our early experience with surgical coronary revascularization under the sole support of Impella 5.0, omitting the use of heart –lung machine in three cases of severe cardiac dysfunction due to complex ischemic heart disease. Effective circulatory support intraoperatively and postoperatively speaks in favor of this technique in selected patients. (Source: Journal of Artificial Organs)

Lung ultrasound for the assessment of lung recruitment in neonates with massive pneumothorax during extracorporeal membrane oxygenation: a case report
We report a case of a neonate who had severe hypoxemia with persistent pulmonary hypertension and massive pneumothorax due to meconium aspiration syndrome and was treated with ECMO. Positive pressure mechanical ventilation resulted in persistent massive air leakage from the disrupted pulmonary tissue. When ECMO was initiated, a “total lung rest” ventilation strategy was used to facilitate healing of the lung rupture and absorption of the pneumothorax. After complete absorption of the pneumothorax, lung recruitment was performed by progressively increasing the positive end-expiratory pressure under the guidance of lung ...

A three-dimensional biomodel of type A aortic dissection for endovascular interventions
AbstractThoracic endovascular aortic repair is widely used for type B aortic dissection. However, there is no favorable stent-graft for type A aortic dissection. A significant limitation for device development is the lack of an experimental model for type A aortic dissection. We developed a novel three-dimensional biomodel of type A aortic dissection for endovascular interventions. Based on Digital Imaging and Communication in Medicine data from the computed tomography image of a patient with a type A aortic dissection, a three-dimensional biomodel with a true lumen, a false lumen, and an entry tear located at the ascendin...
