Incidental Finding of a Large Right Atrial Thrombus in a Patient With Cerebral Lymphoma.

Right atrial (RA) masses are rare, challenging to diagnose, and potentially life-threatening with high mortality if untreated. We present a patient presenting with diffuse large B-cell lymphoma in the brain that was incidentally found to have a large RA mass. For a better definition of the RA mass, extensive workup using multimodality imaging including chest computed tomography, transthoracic echocardiography, transesophageal echocardiography, cardiac magnetic resonance imaging, and left heart catheterization was warranted. The imaging demonstrated a large RA mass extending through the tricuspid valve into the right ventricle and superior and inferior vena cava without a mobile component. The mass was then successfully resected, and further histology examination was performed to rule out lymphoma and rare subtypes of diffuse large B-cell lymphoma. The comprehensive workup proved the RA mass to be a calcified thrombus rather than a direct metastatic spread of lymphoma.

Predictors of 90-Day Readmission and in-Hospital Mortality in Takotsubo Cardiomyopathy: An Analysis of 28,079 Index Admissions.

BACKGROUND: Takotsubo cardiomyopathy (TC) is diagnosed in 1% to 2% of patients presenting with suspected acute coronary syndromes. Readmission patterns after TC have been less studied. Thus, we sought to perform a study to evaluate the etiologies, trends, and predictors of 90-day readmission in TC. METHODS: The Nationwide Readmissions Database (NRD), 2014, was used to select the study cohort. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code 429.83 was used to identify TC. Admissions within 90 days of index admission were considered early readmissions. Readmission etiologies were identified by an ICD-9-CM code. Hierarchical multivariate models were used to evaluate predictors of early readmission. RESULTS: A total of 28,079 patients were identified during the study period, of whom 24.3% (n = 6841) were readmitted within 90 days of discharge. In-hospital mortality during index admissions was 5.69%. The most common etiologies for readmission were cardiac (18.56%), respiratory (17.20%), and infections (13.12%). Among cardiac complications, acute heart failure was the most common etiology (7.48%). The highest number of readmissions happened on the first day after discharge (n = 125). On multivariate analysis, the age of 50-64 years, diabetes, heart failure, chronic pulmonary disease, peripheral vascular disease, anemia, and malignancy were shown to be significant predictors of readmission. Patients of female gender are less likely to be readmitted and have lower in-hospital mortality. CONCLUSIONS: Patients with TC are highly likely to be readmitted within the first month after discharge, most likely with secondary to cardiac or respiratory complications. These findings warrant close post-discharge transition to reduce morbidity and improve healthcare outcomes. SUMMARY: This analysis from the Nationwide Readmission Database outlines a detailed analysis on etiologies, trends, and predictors of 90-day readmission for patients presenting with takotsubo cardiomyopathy.
