Extended and Safe Support with the CentriMag® Temporary Ventricular Assist Device Implanted with Skirted-Cannula Technique.

Objectives: CentriMag® (Abbott, Pleasanton, CA, USA) is indicated for temporary circulatory support for up to 30 days. Extended support is not uncommon, and the results vary considerably. Herein, we review our experience on extended support. Methods: We retrospectively analyzed 19 patients supported with CentriMag as a bridge to recovery, long-term ventricular assist device or transplantation from September 2011 to October 2021. Results: Nineteen patients (16 men and 3 women; mean age 51.7 ± 9.2 years) had CentriMag left ventricular assist device (LVAD) implantation with the skirted-cannula technique. Twelve (63.2%), 6 (31.6%), and 1 (5.3%) patient were in INTERMACS 1, 2, and 3, respectively. The aims of support were bridge-to-decision in 3 patients (15.8%), and bridge-to-transplantation in 16 patients (84.2%). Fourteen patients were supported for longer than 30 days, while 5 patients had their CentriMag removed before 30 days. Of the 5 patients supported for less than 30 days, 3 died early after implantation due to complications of prolonged shock. The other 2 patients were successfully transplanted. Among the 14 patients supported for longer than 30 days, 1 patient died after transplantation and 13 patients survived either after transplantation or weaning off CentriMag. The overall 1-year survival rate was 73.7%. The duration of support for all patients ranged from 6 to 191 days (64 ± 61 days; median 41 days). Conclusions: The skirted cannula technique for apical cannulation in implantation of CentriMag LVAD is an easy, safe and durable technique. Immediate post-operative and long-term complications are not common. Its use over 30 days is associated with acceptable survival.

Massive Vespa basalis stings induce an envenoming syndrome.

Envenoming syndrome induced by massive Vespa basalis stings is a critical condition. Severe systemic reaction may present with hemolytic activity and rhabdomyolysis, leading diffuse alveolar hemorrhage, adult respiratory distress syndrome, coagulopathy, and multiple organs failure. In severe envenoming syndrome population, extracorporeal membrane oxygenation (ECMO) may be considered for unstable hemodynamic status. However, few studies reported ECMO in venom-induced disseminated intravascular coagulation patients. Here, we provide a case presented with pulmonary hemorrhage due to multiple Vespa basalis stings tried to rescue by veno-arterial extracorporeal membrane oxygenation. We also highlight that early recognition of venom-induced disseminated intravascular coagulation by checking coagulation profile in high risk patients may prevent from poor outcome.

Surgical repair of a left main coronary artery aneurysm.

We report the repair of a 6.5 × 5.3-cm left main coronary artery aneurysm by marsupialization of the aneurysm sac and coronary artery bypass grafting.

Clinical experience of infective endocarditis complicated by acute cerebrovascular accidents.

BACKGROUND/OBJECTIVE: To evaluate the clinical results of patients with infective endocarditis (IE) complicated by acute cerebrovascular accidents (CVAs). METHODS: A total of 44 patients with IE complicated by CVA at admission were retrospectively analyzed in a single medical institute from 2005 to 2011. At the time of admission, 18 patients were diagnosed with hemorrhagic stroke, and 26 patients were diagnosed with ischemic stroke. Fifteen patients received surgical intervention during hospitalization. RESULTS: The hospital mortality rate was 38.9% for the hemorrhagic stroke group and 42.3% for the ischemic stroke group (p = 0.821). The mortality rate was 33.3% for the surgical group and 44.8% for the nonsurgical group (p = 0.531). At 30 days of hospitalization, 45.8% of the patients experienced an adverse event (defined as death due to organ failure, restroke, cardiogenic shock, or septic shock during the treatment period), and the attrition rate was 1.5% per day. Surgery performed after the adverse events increased mortality (80.0%) compared with surgery performed on patients with no adverse events (10.0%; p = 0.017). A Cox regression analysis revealed that creatinine > 2 mg/dL, diabetes, and staphylococcal infection were the risk factors of the adverse events. CONCLUSION: Early surgical intervention for IE with ischemic stroke may prevent adverse events, particularly in patients with impaired renal function, diabetes, or staphylococcal infection. A delay in operation of > 30 days is recommended after hemorrhagic stroke.

Modified Norwood Procedure for Tricuspid Atresia, Transposition of Great Arteries, and Hypoplastic Right Arch With Complete Vascular Ring.

We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. In this technique, we applied dual arterial cannulation to avoid circulation arrest during neoaortic reconstruction, and also corrected the arch laterality during the Norwood stage I palliation procedure. Pulmonary flow was supplied by the Blalock-Taussig shunt. Postoperative imaging revealed the patent left neoaortic arch, and the vascular ring was relieved with a patent tracheobronchial tree.

Modified Warden Procedure Using the Concept of Senning Operation: Repair Without Any Patch.

Various surgical techniques have been proposed to repair a partial anomalous pulmonary venous connection to the superior vena cava, such as the single-patch, the double-patch, and the caval division (Warden) techniques. The limited growth potential of the artificial patch, stenosis of the cavoatrial channel or rerouted pulmonary vein channel, and the risk of sinus node dysfunction were possible adverse events. We here describe a modified Warden procedure without any patch in a 6-month-old infant. Using the concept of the Senning atrial switch technique, the interatrial septum and the free wall of the right atrium were used to baffle the anomalous pulmonary vein into the left atrium.
