Abstract
New-onset systolic heart failure (HF) after liver transplantation (LT) is a significant cause of morbidity and mortality; however, its characteristics are still insufficiently delineated. HF may involve the left ventricle (LV), right ventricle (RV), or both ventricles. We explored the incidence, characteristics, etiologies, risks, involved cardiac chambers, and outcomes of HF after LT. Methods This study included 528 adult patients with preoperative LV ejection fraction ≥ 55% who underwent LT between 2016 and 2020. The primary outcome was new-onset systolic HF, defined by the presence of clinical signs, symptoms, and echocardiographic evidence of reduced LVejection fraction <50% and RV dysfunction within the first year after LT. Results Thirty-one patients (6%) developed systolic HF within a median of 9 d (1-364). Of those, 23% of patients had ischemic HF, whereas 77% had nonischemic HF. Nonischemic HF was caused by stress (11), sepsis (8), or other factors (5). Nonischemic HF was secondary to isolated LV failure in 58% of patients or RV ± LV failure in 42% of patients. Recursive partitioning identified subgroups with varying risks and uncovered interaction between variables. HF risk increased from 4.2% to 13% when epinephrine and/or norepinephrine drips were used intraoperatively (P < 0.01). When no epinephrine and/or norepinephrine were used, HF risk increased from 3.1% to 38.5% if baseline hemoglobin was <7.2 g/dL (P < 0.01). When baseline hemoglobin was ≥7.2 g/dL, HF risk increased from 0% to 5.2% when ≥3500 mL crystalloid was used intraoperatively (P < 0.01). Posttransplant first-year survival and reversibility of HF depended on the etiology (stress, sepsis, ischemia, etc) and cardiac chamber involvement (isolated LV or RV ± LV). RV dysfunction was associated with inferior recovery of cardiac function and poorer survival than nonischemic isolated LV dysfunction (50% versus 70%, respectively). Conclusions Posttransplant new-onset HF is mostly nonischemic in nature and is associated with increased morbidity and mortality.

Abstract
Portopulmonary hypertension, a type of pulmonary arterial hypertension in the setting of cirrhotic or noncirrhotic portal hypertension, is associated with elevated morbidity and mortality during and after transplantation. Uncontrolled portopulmonary hypertension may prevent or delay listing for transplant candidates, and the prognosis without treatment and ultimately transplant is extremely poor. We present a 29-year-old White woman, who had a post-liver transplant at infancy due to biliary atresia. Later on, she developed extensive portal vein thrombosis and portopulmonary hypertension and underwent a multivisceral transplant (liver, stomach, pancreaticoduodenal complex, and small and large intestine). Preoperative mean pulmonary artery pressure was <30 mm Hg with a pulmonary vascular resistance of <300 dynes.s/cm5 on oral sildenafil and intravenous epoprostenol. Intraoperatively, management required comprehensive transfusion protocols, a careful balance between correcting blood loss and preventing thrombosis. Intravenous epoprostenol, sildenafil, milrinone, and inhaled nitric oxide were used to reduce elevated mean pulmonary artery pressure and right ventricular strain associated with vascular clamping, reperfusion, and massive fluid shifts. Nitric oxide and epoprostenol use unleashed antiplatelet effects on a patient already susceptible to coagulopathy. A multimodal and multidisciplinary approach continued throughout the surgery and in the postoperative period, which led to a successful outcome.

Abstract
BACKGROUND Anesthesia practitioners are at risk for percutaneous injuries by blood-contaminated needles and sharp objects that may result in transmission of HIV and hepatitis viruses. Reporting these injuries is important for early prevention and management of blood-borne infections. We investigated the occurrence, reporting, characteristics, and outcome of contaminated percutaneous injuries (CPI) in anesthesia residents, fellows, and faculty. METHODS A cross-sectional anonymous survey electronically distributed to all 214 anesthesia practitioners at a large academic multihospital-based anesthesia practice in Florida, USA. RESULTS The overall response rate was 51% (110/214) (60% (50/83) for residents, 50% (8/16) for fellows, 45% (52/115) for anesthesia faculty). 59% (65/110) (95%CI: 50,68) of participants reported having one or more CPI during their years of anesthesia practice (residents 42% (95%CI: 29,55), fellows 50%, faculty 77% (95%CI: 66,88). Numbers of CPI per anesthesia practitioner who answered survey was 0.58 for residents, 0.75 for fellows, and 1.5 for faculty.Within the last 5 years, 35% (95%CI: 26,44) of participants had one or more CPI (39% of residents, 50% of fellows, 29% of faculty. CPI in the last 5 years in faculty older than 45 years of age was 12% (3/25) compared to 44% (12/27) in faculty younger than 45 years of age.Analyzing data from practitioners who had one CPI revealed that 70% (95%CI: 55,85) reported the incident at the time of injury (residents 85%, fellows 100%, faculty 58%). Hollow-bore needles constituted 73.5% (95%CI: 59,88) of injuries. As per participants responses, 17% (18/103) of CPIs received post-exposure prophylaxis and there were zero seroconversions. CONCLUSION Based on our study results, most anesthesia practitioners will sustain a CPI during their years of practice. Despite some improvement compared to historic figures, occurrence of CPI continues to be high and reporting of percutaneous injuries remains suboptimal among anesthesia residents. A fifth of injuries in the perioperative setting are from an infected source and require postexposure prophylaxis. Although no infections were reported due to CPI exposure in this study, findings underscore the need for more education and interventions to reduce occupational blood exposures in anesthesia practitioners and improve reporting.

Abstract
We describe herein a case of bioprosthetic valve malfunction, which closely imitates a stuck valve. Although the term "stuck" was used originally for the immovable mechanical valve leaflets, the echocardiographic manifestation of this malfunction is similar to those of a mechanical one. The clinical presentation of the stuck bioprosthesis is, however, far more benign than a stuck mechanical valve. Familiarity with this entity is important.

Abstract
OBJECTIVES We sought to determine the role of preoperative predictors, particularly ischemia, on preoperative thallium scanning (PTS) and coronary revascularization on low-level and conventional troponin elevations after major vascular surgery. BACKGROUND Postoperative cardiac troponin (cTn) elevations have recently been shown to predict both short- and long-term mortality after vascular surgery. METHODS The perioperative data, including PTS and subsequent coronary revascularization, continuous perioperative 12-lead ST-segment trend monitoring, cTn-I and/or cTn-T, and creatine kinase-MB fraction in the first three postoperative days, were prospectively collected in 501 consecutive elective major vascular procedures. RESULTS Moderate to severe inducible ischemia on PTS was associated with a 49.0% incidence of low-level (cTn-I >0.6 and/or cTn-T >0.03 ng/ml) and 22.4% conventional (cTn-I >1.5 and/or cTn-T >0.1 ng/ml) troponin elevation. In contrast, patients with preoperative coronary revascularization had 23.4% and 6.4% low-level and conventional troponin elevations, respectively, similar to patients without ischemia on PTS. By multivariate logistic regression, ischemia on PTS was the most important predictor of both low-level and conventional troponin elevations (adjusted odds ratios [ORs] 2.5 and 2.7, p = 0.02 and 0.04, respectively), whereas preoperative coronary revascularization predicted less troponin elevations (adjusted ORs 0.35 and 0.16, p = 0.045 and 0.022, respectively). Postoperative ischemia (>10 min), the more so prolonged (>30 min) ischemia was the only independent predictor of troponin elevation if added with the preoperative predictors to the multivariate analysis (ORs 15.8 and 22.8, respectively, p < 0.001). CONCLUSIONS Troponin elevations occur frequently after vascular surgery. They are strongly associated with postoperative ischemia, predicted by inducible ischemia on PTS, and reduced by preoperative coronary revascularization.

Abstract
OBJECTIVES The aim of this study was to determine the long-term prognosis with postoperative markers of myocardial ischemia and infarction. BACKGROUND Cardiac troponins (cTn) are superior to creatine kinase-MB fraction (CK-MB) in detecting perioperative myocardial infarction (PMI). However, their threshold levels signifying PMI and their long-term prognostic value are not yet determined. METHODS A cohort of 447 consecutive patients who underwent 501 major vascular procedures was prospectively studied. Perioperative continuous 12-lead electrocardiogram monitoring, cardiac troponin-I (cTn-I) and/or cardiac troponin-T (cTn-T), and CK-MB levels on the first three postoperative days, and long-term survival were determined. The association of different cutoff levels of CK-MB, troponin, and ischemia duration with long-term survival was investigated. RESULTS Between 14 (2.9%) and 107 (23.9%) of the patients sustained PMI, depending on the biochemical criteria used. Elevated postoperative CK-MB, cTn, and prolonged (>30 min) ischemia, at all cutoff levels examined, predicted long-term mortality independent of the preoperative predictors: patient's age, type of vascular surgery, previous myocardial infarction, and renal failure (Cox multivariate analysis). Both CK-MB >10% and cTn-I >1.5 ng/ml and/or cTn-T >0.1 ng/ml independently predicted a 3.75-fold and 2.06-fold increase in long-term mortality (p = 0.006 and 0.012, respectively). Similarly, both CK-MB >5% and cTn-I >0.6 ng/ml and/or cTn-T >0.03 ng/ml independently predicted a 2.15-fold and 1.89-fold increase in mortality (p = 0.018 and 0.01, respectively). Patients with both these markers elevated had a 4.19-fold increase in mortality (p < 0.001). CONCLUSIONS Postoperative CK-MB and troponin, even at low cutoff levels, are independent and complementary predictors of long-term mortality after major vascular surgery.
