Background The current gold standard for donor heart preservation is a three-bag-technique and storage in a cooler filled with slush ice. This technique can cause freezing injury with protein denaturation. We report our early experience with a single-use disposable device (SherpaPak™, Paragonix Technologies, MA, USA) specifically designed for sterile permanent temperature-controlled transportation of donor hearts. Methods In this case control study with 2:1 matching we identified 21 patients after heart transplantation depending on type of organ transport (standard three-bag-technique vs. SherpaPak™). The outcome after donor heart storage in the SherpaPak™ was compared with donor heart transportation with the standard technique. Results Since July 2018 seven patients (5 males; mean age 50.3±13.2years) underwent heart transplantation with the SherpaPak™ system. Cold ischemic time was longer in the SherpaPak™ group (207.7±23.3 vs. 181.6±21.9, P=0.027). SherpaPak™ kept the organ temperature at 5.1±0.8 °C, with an average outside temperature of 21.4±3.6 °C. Among all 21 transplanted patients four developed fatal early graft failure (28.6% vs. 21.4%, P=0.432). Over the first hours we noticed no difference in hemodynamic parameters, CK-MB levels or vasoactive-inotropic score. During first follow-up we noticed slightly better right heart function in the SherpaPak™ group (TAPSE 17.83±2.71 vs. 14.52±2.61 mm, P=0.020). We identified no positive blood cultures in the SherpaPak™ group within the first 30 days after heart transplantation. Conclusions The SherpaPak™ provides a constant temperature during transportation with permanent monitoring, never dropping below 4 °C. Organs transported with this novel device showed a normal perioperative function.
Background: Rapid deployment aortic valve systems may ease aortic replacement in challenging minimally invasive approaches.We report our results of a single-center observational study with the Edwards Rapid Deployment (RD) Valve System in Patients with a Right Anterior Mini-Thoracotomy Approach (RAT-AVR).Methods: From 9/2013 to 3/2015, 30 consecutive patients received RAT-AVR with the RD valve system.Hemodynamic parameters and clinical outcome were assessed perioperatively, and at hospital discharge.To evaluate the learning curve patients were divided into three groups (Group 1; No.1-10 RD-AVR, group 2; No.11-20 RD-AVR, and group 3; No.21-30 RD-AVR) according to the chronological sequence. Results:The median aortic clamp and cardiopulmonary bypass time for the entire patient cohort was 44.5 (35.0-54.3)min and 75.0 (63.8-102) min.Aortic clamp time (p=0.011)and cardiopulmonary bypass time (p=0.032)differed significantly between groups.Mortality rate was 6.7% and conversion rate was 6.7%, with no differences between groups.There was neither paravalvular leakage nor patient prosthesis mismatch.Conclusions: RAT-AVR with the RD valve system is a feasible safe and reproducible procedure.Reproducible short crossclamp-times can be achieved in a RAT-AVR setting within a short period of time, which might increase the acceptance of RAT-AVR among surgeons.
There is growing evidence from the literature that right anterior minithoracotomy aortic valve replacement (RAT-AVR) improves clinical outcome. However, increased cross clamp time is the strongest argument for surgeons not performing RAT-AVR. Rapid deployment aortic valve systems have the potential to decrease cross-clamp time and ease this procedure. We assessed clinical outcome of rapid deployment and conventional valves through RAT.
ObjectivesSecondary sclerosing cholangitis in critically ill patients is a rapidly progressing disease leading to biliary fibrosis and cirrhosis. We describe the course of sclerosing cholangitis in critically ill patients after cardiac surgery and compare this with matched patients.MethodsA retrospective search for "secondary sclerosing cholangitis" and "liver and/or hepatic failure" in all adult patients (aged 18-93 years) who underwent cardiac surgery from April 2007 to March 2016 identified 192 of 8625 patients. Of those, 12 were diagnosed with sclerosing cholangitis in critically ill patients (incidence, 0.14%). A 3:1 matching was performed. Laboratory values, pharmacologic requirements, ventilation times, mechanical circulatory support, and endoscopic retrograde cholangiopancreatography studies were extracted from the hospital database.ResultsA total of 9 men and 3 women were affected (age 71 years; range, 59.8-75.5 years). Critically ill patients with sclerosing cholangitis required vasoconstrictors and inotropes longer than control patients (norepinephrine 356.5 hours [264.5-621] vs 68 hours [15-132.5], P = .003; enoximone 177 hours [124.3-249.5] vs 48.5 hours [12-81 hours], P < .001, respectively). Critically ill patients with sclerosing cholangitis had longer intubation time (628.5 hours [377.3-883] vs 25 hours [9.8-117.5]; P < .001) and more surgical revisions (3 [2.5-6] vs 1 [0-2], P = .003) than the matching group. Bilirubin (23.3 mg/dL [14.4-32.9] vs 1 mg/dL [0.6-2.7]; P < .001), gamma-glutamyltransferase (1082.3 U/L [259.5-2265.7] vs 53.8 U/L [35.1-146]; P < .001), and alkaline phosphatase (751.5 U/L [372-1722.3] vs 80.5 U/L [53.3-122]; P < .001) were higher in critically ill patients with sclerosing cholangitis. One critically ill patient with sclerosing cholangitis underwent successful liver transplantation. A total of 11 patients sclerosing cholangitis died (92%) versus 12 patients (33%, P < .001) in the control group.ConclusionsSclerosing cholangitis in critically ill patients is a fatal complication in patients undergoing cardiac surgery who have a complicated postoperative course with prolonged vasoconstrictor, inotropic, and respiratory therapy, or who require frequent surgical revisions. Liver transplantation remains the only curative option but is often precluded by the age and critical state of patients undergoing cardiac surgery.
Current concepts for tricuspid valve surgery recommend concomitant tricuspid valve reconstruction (TVR) utilizing annuloplasty devices over simple suture annuloplasty.
Background: Applying the gender lens to risk factors and outcome after adult cardiac surgery is of major clinical interest, as the inclusion of sex and gender in research design and analysis may guarantee more comprehensive cardiovascular science and may consecutively result in a more effective surgical treatment as well as cost savings in cardiac surgery. Methods: We have reviewed classical cardiovascular risk factors (diabetes, arterial hypertension, hyperlipidemia, smoking) according to a gender-based approach. Furthermore, we have examined comorbidities such as depression, renal insufficiency, and hormonal influences in regard to gender. Gender-sensitive economic aspects have been evaluated, surgical outcome has been analyzed, and cardiovascular research has been considered from a gender perspective. Results: The influence of typical risk factors and outcome after cardiac surgery has been evaluated from a gender perspective, and the gender-specific distribution of these risk factors is reported on. The named comorbidities are listed. Economic aspects demonstrated a gender gap. Outcome after coronary and valvular surgeries as well as after heart transplantation are displayed in this regard. Results after postoperative use of intra-aortic balloon pump are shown. Gender-related aspects of clinical and biomedical cardiosurgical research are reported. Conclusions: Female gender has become an independent risk factor of survival after the majority of cardiosurgical procedures. Severely impaired left ventricular ejection fraction independently predicts survival in men, whereas age does in females.
