RESUMEN
BACKGROUND: Although acute kidney injury (AKI) has been established as an independent risk factor for in-hospital mortality for patients on veno-arterial (V-A) extracorporeal membranous oxygenation (ECMO), the impact of Kidney Disease Improving Global Outcomes (KDIGO) stages of AKI has yet to be elucidated as a risk factor. METHODS: We conducted a retrospective analysis of patient outcomes based on KDIGO stages of AKI at a single institution. The analysis was a cohort of 179 patients; 66 without AKI, 19 with stage 1 AKI, 18 with stage 2 AKI, and 76 with stage 3 AKI. RESULTS: Every 1-year increase in age was associated with 4% increased odds of mortality at 30 days (95% confidence interval [CI] 1.01, 1.07; p = 0.004). The presence of AKI at any stage was associated with 59% increased odds of 30-day mortality (95% CI 0.81, 3.10; p = 0.176). The presence of stage 1 AKI was associated with a 5% decreased odds of 30-day mortality (95% CI 0.32, 2.89). The presence of stage 2 AKI (odds ratio [OR] 2.29, 95% CI 0.69, 7.55; p = 0.173) and stage 3 AKI (OR 1.68, 95% CI 0.81, 3.46; p = 0.164) was associated with increased odds of 30-day mortality. CONCLUSION: Based on our single-center study, higher KDIGO stages of AKI likely have increased odds of mortality at 30 days. Larger studies are needed to confirm these findings.

Refractory right ventricular failure has significant morbidity and mortality. Extracorporeal membrane oxygenation is indicated when medical interventions are deemed ineffective. However, it is still being determined if one configuration is better. We conducted a retrospective analysis of our institutional experience comparing the peripheral veno-pulmonary artery (V-PA) configuration versus the dual-lumen cannula with the tip in the pulmonary artery (C-PA). The analysis of a cohort of 24 patients (12 patients in each group). There was no difference in survival after hospital discharge (58.3% in the C-PA group compared to 41.7% in the V-PA group, p = 0.4). Among the C-PA group, there was a statistically significant shorter ICU length of stay (23.5 days [interquartile range {IQR} = 19-38.5] vs. 43 days [IQR = 30-50], p = 0.043) and duration of mechanical ventilation (7.5 days [IQR = 4.5-9.5] compared to (16.5 days [IQR = 9.5-22.5], p = 0.006) in the V-PA group. In the C-PA group, there were lower incidents of bleeding (33.33% vs. 83.33%, p =0.036) and combined ischemic events (0 vs. 41.67%, p = 0.037). In our single-center experience, the C-PA configuration might have a better outcome than the V-PA one. Further studies are needed to confirm our findings.

A 61-year-old male presented with a history of ischemic cardiomyopathy requiring left ventricular assist device (LVAD) implantation 9 months prior to presentation. The patient was on aspirin and warfarin as part of his LVAD management. The patient had chest pain and was found to have non-ST elevation myocardial infarction. Despite being on warfarin, a subtherapeutic international normalized ratio of 1.6 was measured on admission. Lactate dehydrogenase was 694 U/L (12-146) and high-sensitivity troponin peaked at 47,093 ng/L. Left heart catheterization revealed an extensive aortic root thrombus (AT). AT is an uncommon cause of thromboembolic events in long-term LVAD patients. Thrombotic events in LVAD patients are pump thrombosis, cerebrovascular accidents, heparin-induced thrombocytopenia, and rarely, AT. There is no well-described management of such a rare complication. In our report, we suggest a multidisciplinary approach and consideration of conservative treatment of these patients.

OBJECTIVE: Bleeding and thrombosis are common complications during Extracorporeal Membrane Oxygenation (ECMO) support for COVID-19 patients. We sought to examine the relationship between inflammatory status, coagulation effects, and observed bleeding and thrombosis in patients receiving venovenous (VV) ECMO for COVID-19 respiratory failure. STUDY DESIGN: Cross-sectional cohort study. SETTINGS: Quaternary care institution. PATIENTS: The study period from April 1, 2020, to January 1, 2021, we included all patients with confirmed COVID-19 who received VV ECMO support. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Thirty-two patients were supported with VV ECMO during the study period, and 17 patients (53%) survived to hospital discharge. The ECMO nonsurvivors mean lactate dehydrogenase (LDH) levels were markedly elevated in comparison to survivors (1046 u/L [IQR = 509, 1305] vs 489 u/L [385 658], p = 0.003). Platelet/fibrinogen dysfunction, as reflected by the low Maximum Amplitude (MA) on viscoelastic testing, was worse in nonsurvivors (65.25 mm [60.68, 67.67] vs 74.80 mm [73.10, 78.40], p = 0.01). Time-group interaction for the first seven days of ECMO support, showed significantly lower platelet count in the nonsurvivors (140 k/ul [103, 170] vs 189.5 k/ul [ 146, 315], p < 0.001) and higher D-dimer in (21 µg/mL [13, 21] vs 14 µg/mL [3, 21], p < 0.001) in comparison to the survivors. Finally, we found profound statistically significant correlations between the clinical markers of inflammation and markers of coagulation in the nonsurvivors group. The ECMO nonsurvivors experienced higher rate of bleeding (73.3% vs 35.3%, p = 0.03), digital ischemia (46.7% vs 11.8%, p = 0.02), acute renal failure (60% vs 11.8%, p = 0.01) and bloodstream infection (60% vs 23.5%, p = 0.03). CONCLUSION: The correlation between inflammation and coagulation in the nonsurvivors supported with VV ECMO could indicate dysregulated inflammatory response and worse clinical outcomes.

OBJECTIVES: Published discrepancy rates between emergency department (ED) and hospital discharge (HD) diagnoses vary widely (from 6.5 to 75.6%). The goal of this study was to determine the extent of diagnostic discrepancy and its impact on length of hospital stay (LOS), up-triage to the intensive care unit (ICU) and in-hospital mortality. METHODS: A retrospective chart review of adult patients admitted from the ED to a hospitalist service at a tertiary hospital was performed. The ED and HD diagnoses were compared and classified as concordant, discordant, or symptom diagnoses according to predefined criteria. Logistic regression analysis was conducted to examine the associations of diagnostic discordance with in-hospital mortality and up-triage to the ICU. A linear regression model was used for the length of stay. RESULTS: Of the 636 patients whose records were reviewed, 418 (217 [51.9%] women, with a mean age of 64.1 years) were included. Overall, 318 patients (76%) had concordant diagnoses, while 91 (21.77%) had discordant diagnoses. Only 9 patients (2.15%) had symptom diagnoses. A discordant diagnosis was associated with increased mortality (OR: 3.64; 95% CI: 1.026-12.91; p=0.045) and up-triage to the ICU (OR: 5.51; 95% CI: 2.43-12.5; p<0.001). The median LOS was significantly greater for patients with discordant diagnoses (7 days) than for those with concordant diagnoses (4.7 days) (p=0.004). Symptom diagnosis did not affect the mortality or ICU up-triage. CONCLUSIONS: One in five hospitalized patients had discordant HD and admission diagnoses. This diagnostic discrepancy was associated with significant impacts on patient morbidity and mortality.

Methicillin-resistant staphylococcus aureus (MRSA) pericarditis is a rare life-threatening infection. A 46-year-old female with hypertension, acquired immunodeficiency syndrome (AIDS) and recurrent neck abscesses, presented with a neck abscess and sepsis. Bloody purulent drainage from the abscess was found and antibiotics were started. Drainage was positive for MRSA. Four days after, course was complicated by acute pericarditis and pericardial tamponade; pericardial fluid was drained and was positive for MRSA. Vancomycin was continued, and aspirin and colchicine were started. Two days later, there was a recurrent pericardial fluid collection with loculation. Surgery was thought to be dangerous in the setting of CD4 count of 12. She was managed conservatively thereafter, with vancomycin, aspirin and colchicine, and was successfully discharged from the hospital.
RESUMEN
Cardiac tumors are relatively rare. Secondary cardiac tumors are by far more common than primary cardiac tumors. Cardiac involvement may occur secondary to hematogenous metastases, direct invasion, or tumor growth into the venous system and extension into the right atrium. Patients can present with a spectrum of conditions, including embolization, obstruction of ventricular outflow tracts, direct invasion of myocardium causing impaired myocardial function, invasion of surrounding tissue, interference with valvular function causing valvular regurgitation, or constitutional non-specific signs and symptoms. Imaging modalities are essential for diagnosis. Management is mostly surgical, but can include other medical strategies as well. We present a case of a 65-year-old male with hepatocellular carcinoma with direct invasion to the heart through the venous system.
RESUMEN
This is a case of a 56-year-old female who presented with inferior ST segment elevation myocardial infarction (STEMI), treated with percutaneous intervention (PCI), which was complicated by a retained guidewire extending from left circumflex artery (at location of obtuse marginal (OM) stent) through the ascending aorta, the right brachiocephalic artery and into the right axillary artery. Patient underwent cardiac CT, with maximum intensity projection image showing the course of the retained guidewire. Percutaneous retrieval was deferred due to risk of damaging the stent, and the patient initially deferred coronary artery bypass (CABG) and surgical retrieval as. She was discharged on triple therapy with Aspirin, Clopidogril and Apixaban for 3â¯months with no bleeding or thromboembolic complications on a 3-month follow up with cardiology clinic, during which rediscussion of risks and benefits of CABG and surgical retrieval or retained wire took place with the patient. Patient agreed to undergo the procedure and guidewire was retrieved surgically and CABG was done.
