Ventricular tachycardia (VT) in the setting of left ventricular assist device (LVAD) therapy has been well described. We present a case of incessant ventricular tachycardia resulting in severe right ventricular (RV) failure and subsequent left ventricular (LV) cavity obliteration, which in turn diminished the feasibility of initial attempt at VT ablation.

A 32-year-old motorcyclist who was hit by a tram subsequently presented with blunt force thoracic trauma, a pelvic fracture and a penetrating injury to the left lower extremity. Coagulopathy persisted following surgery of the leg and pelvic vascular intervention. Bedside thoracotomy was performed to treat pneumothorax and pneumopericardium. Severe hypoxemia secondary to lung failure ensued, which required venovenous extracorporeal membrane oxygenation (VV ECMO) support. On the third day after the trauma, ultra-protective mechanical ventilation was not possible due to non-existent lung compliance; thus, the ventilator was disconnected, and the T-piece was connected to the blocked tracheal tube left in the airway...

The purpose of this study was to evaluate the outcome improvements after total hip arthroplasty (THA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) in patients who underwent THA with a navigation system in our institutions. The subjects were 219 patients. All patients had adequate data to allow complete scoring of the WOMAC for a 1-year postoperative follow-up. CT-based navigation was used in all THAs. Postoperatively, no restrictions were imposed on patients' ADL. One year after surgery, the average WOMAC pain subscale score was 1...

We report a rare case of papillary muscle rupture due to myocardial infarction during left ventricular assist device support. A 69-year-old woman with cardiogenic shock due to acute myocardial infarction requiring venoarterial extracorporeal membrane oxygenation support was transferred for further surgical intervention. Six days after the event, extracorporeal membrane oxygenation was decannulated, and an extracorporeal left ventricular assist device was implanted. On postoperative day 11, she suffered from sudden onset hypoxia due to pulmonary edema...

The benefit of whole-body hypothermia in preventing ischemic injury during cardiac surgical operations is well documented. However, application of hypothermia during in vivo total artificial heart implantation has not become widespread because of limited understanding of the proper techniques and restrictions implied by constitutional and physiological characteristics specific to each animal model. Similarly, the literature on hypothermic set-up in total artificial heart implantation has also been limited. Herein we present our experience using hypothermia in bovine models implanted with the Cleveland Clinic continuous-flow total artificial heart...

Photoelectric dye-coupled polyethylene film, designated Okayama University type-retinal prosthesis or OUReP™, generates light-evoked surface electric potentials and stimulates neurons. The dye-coupled films or plain films were implanted subretinally in both eyes of 10 Royal College of Surgeons rats with hereditary retinal dystrophy at the age of 6 weeks. Visual evoked potentials in response to monocular flashing light stimuli were recorded from cranially-fixed electrodes, 4 weeks and 8 weeks after the implantation...

The number of patients with end-stage heart failure treated by a left ventricular assist device (LVAD) is dramatically increasing, because the LVAD has been widely accepted for its clinical results. According to the initiation of destination therapy, the prevalence of malignancy in patients with an LVAD is estimated to increase. In patients with LVADs, abdominal surgery for visceral malignancy is associated with technical difficulties because of the presence of an LVAD pump or the driveline which is located transversely in the preperitoneal space...

The objective of the present study is to evaluate the effect of filtration coefficient and internal filtration on dialysis fluid flow and mass transfer coefficient in dialyzers using dimensionless mass transfer correlation equations. Aqueous solution of vitamin B12 clearances were obtained for REXEED-15L as a low flux dialyzer, and APS-15EA and APS-15UA as high flux dialyzers. All the other design specifications were identical for these dialyzers except for filtration coefficient. The overall mass transfer coefficient was calculated, moreover, the exponents of Reynolds number (Re) and film mass transfer coefficient of the dialysis-side fluid (k D) for each flow rate were derived from the Wilson plot and dimensionless correlation equation...

Regional cerebral oximetry using near-infrared spectroscopy device, an INVOS 5100 C (Medtronic, Minneapolis, MN, USA), during cardiac surgery aims to avoid perioperative neurological impairment, especially during cardiopulmonary bypass. However, it is not uncommon to encounter critically low initial cerebral regional oxygen saturation or a low value unresponsive to intervention. Therefore, it is important to identify factors associated with low saturation value other than true cerebral hypoxia. We investigated the relationship between preoperative regional cerebral oxygen saturation and clinical variables during cardiac surgery...

Intraoperative allergic reactions are rare but serious events associated with increased morbidity and mortality. We report the salvage of intraoperative anaphylaxis leading to extreme hypercapnic respiratory failure by veno-venous extracorporeal membrane oxygenation (ECMO). A 38-year-old woman undergoing thyroidectomy developed intractable bronchospasm after administration of atracurium, leading to extreme hypercapnic respiratory failure (PaCO2 > 250 mmHg, pH 6.773). After the failure of conventional medical therapy and ventilatory optimization, the patient was connected to a veno-venous ECMO circuit...

Nipro-Toyobo-paracorporeal pulsatile flow VAD (Nipro VAD; Nipro, Osaka, Japan) has been used most commonly as a paracorporeal VAD (p-VAD) in Japan. There are few reports describing clinical course of post LVAD explantation and its complication. We herein present two cases of apical abscess after the explantation of the device. SSI is a main risk factor of formation of the apical abscess at the time of LVAD explantation. It is mandatory to perform sufficient debridement and closure of the layers including abdominal muscle and anterior abdominal fascia at exit sites in the explantation surgery...

Sepsis-induced cardiogenic shock in combination with severe acute respiratory failure represents a life-threatening combination that is often refractory to the conventional methods of treatment. We describe the case of a 33-year-old patient who developed acute cardiovascular collapse and ARDS secondary to superinfection of Panton-Valentine leukocidin-positive Staphylococcus aureus and H1N1 pneumonia who underwent successful combination therapy for severe sepsis-related cardiomyopathy and respiratory failure using extracorporeal membrane oxygenation and cytokine adsorption therapy...

We successfully managed a splenic injury and delayed splenic rupture in a patient with an implantable left ventricular assist device (iLVAD). A 42-year-old man with an iLVAD for idiopathic dilated cardiomyopathy was admitted to our department complaining of dizziness. Laboratory data showed severe anemia, and computed tomography demonstrated a traumatic splenic injury. Following conservative treatment, partial splenic embolization was performed. Fifteen days after the intervention, the patient went into hemorrhagic shock due to delayed splenic rupture...

To improve the efficiency of plasma perfusion on eliminating plasma paraquat (PQ), we designed continuous plasma perfusion of dual cartridges in series (CPPDCS) on Diapact Braun CRRT machine. The goals of this study were to evaluate the effective of CPPDCS on paraquat removal in patients with acute paraquat intoxication. Our results show that the PQ clearance rate of dual cartridges was significantly higher than that of single cartridge at 1st, 2nd, 3(rd), and 4th plasma perfusion. Compared with single-cartridge plasma perfusion, CPPDCS significantly reduced the frequency of cartridge replacement, shorten the time of perfusion...

We successfully controlled infection of a left ventricular assist device by performing pump exchange. A 53-year-old man was implanted with DuraHeart for ischemic cardiomyopathy as a bridge to transplantation. Two years later, he was hospitalized with the diagnosis of driveline infection. The blood cultures detected Pseudomonas aeruginosa. During the admission, he developed brain hemorrhage perhaps due to septic emboli. The chest computed tomography scan revealed a small defect inside the outflow graft of the DuraHeart, which was highly suspected of vegetation...

Platelet-rich plasma (PRP) contains a high concentration of several growth factors and contributes to soft-tissue engineering and wound healing. However, the effect of PRP on human dermal fibroblast proliferation and responses is unknown. This was investigated in the present study using PRP prepared from the whole human blood using the double-spin method. Human dermal fibroblast cultures were established from skin samples collected during plastic surgery. Platelet concentration and growth factor levels in PRP were estimated, and a cell proliferation assay was carried out after PRP treatment...

Patients supported by mechanical circulatory support have to wait for longer periods for heart transplantation in Japan. Infective events are a major complication and influence survival. Here, we present the case of a patient with an implantable left ventricular assist device for 6 months who had the complication of ruptured infective common iliac aneurysm. Graft placement with an omental flap was successfully performed via the alternative surgical approach to avoid percutaneous driveline injury. In samples of aortic specimens, 16S ribosomal DNA gene analysis identified Helicobacter cinaedi...
