Background and Objectives Stress echocardiography is the current standard for cardiac risk stratification of patients undergoing orthotopic liver transplantation (OLT). We aim to evaluate the role of dobutamine stress echocardiography (DSE) in predicting perioperative major adverse cardiac event (MACE) in patients undergoing OLT. Methods This was a single-center retrospective study including 144 OLT patients. Of 144 patients, 118 had DSE. MACE included myocardial infarction (MI), heart failure (HF), cardiovascular and all-cause death 1 year after OLT. Results Our study cohort included 118 patients. The mean age was 57.3±8.2 years (range, 25–72 years). There were 85 men and 33 women, male to female ratio being 2.6:1. Of 118, 15 (13%) had positive DSE and 103 (87%) had negative DSE. Perioperative MACE incidence was 5.9% (95% confidence interval [CI], 2.6–12.3%). In predicting MACE, DSE had sensitivity of 5.6% (95% CI, 0.2–29.4%), specificity 86% (95% CI, 77.3–91.9%), positive predictive value 6.7% (95% CI, 0.3–33.4%), and negative predictive value (NPV) 83.5% (95% CI, 74.6–89.8%). Eighteen patients had MACE in first year post OLT (15%, 95% CI, 9.5–23.3%). Adverse events included cardiogenic shock (2/18), systolic HF (2/18), non-ST-elevated MI (7/18), cardiac mortality (3/18), and all-cause mortality (7/18). The overall complication rate of DSE was 17% (20/118). Conclusions In our cohort, DSE had a low sensitivity but high NPV in predicting perioperative MACE post OLT. A similar trend was noted for DSE in predicting 1-year MACE post OLT. We reiterate the need of a better screening and risk stratification tool for OLT.

The objective of this study was to analyze the three different management modalities for isolated superior mesenteric artery (SMA) dissection. We did a comprehensive literature search and found 703 articles on the initial search, out of which 111 articles consisting of 145 patients were selected for analysis. The mean age was 55.7 years (standard deviation,9.7;33–85) and 80.6% were male. These patients were managed conservatively (41.3%), endovascularly (28.1%) or surgically (30%). The median follow-up was 10 months (interquartile range [IQR], 4–18 months), 12 months (IQR, 6–19 months) and 14 months (IQR, 6–20 months) respectively. Contrast-enhanced computed tomography (CT) was the most commonly used diagnostic tool in the conservative group (43.8%), while conventional CT scan was the most widely used in endovascular (58.1%) and surgical group (50%). 17% percent of the conservative group had SMA angiography for diagnosis, while this was less than 3% in the other groups. Of these patients, 96.7%, 97.4%, and 100.0% recovered successfully in the conservative, endovascular, and surgical groups respectively. There was no significant difference in the mortality between the three groups (Pearson χ2=0.482). This suggests a conservative and endovascular approach could be used in most patients, which can reduce costs and surgery-related morbidity and mortality. Surgical management should be reserved for cases having infarction or widespread bowel ischemia and in cases where other treatment modalities fail.
