Nonbacterial thrombotic endocarditis (NBTE) is illustrated by thrombi deposition on normal heart valves without the presence of bacteremia. It typically occurs in the setting of chronic debilitating diseases such as cancer or autoimmune disease. The pathogenesis involves an endothelial injury in the presence of a hypercoagulable state secondary to the effects of circulatory cytokines, which triggers platelet deposition. It usually forms on the upstream atrial surface of the mitral and tricuspid valves and the ventricular surface of the pulmonic and aortic valves and occurs most commonly in the fourth to eighth decades of life with no specific gender predisposition. These vegetations have a distinct morphology that varies from infective endocarditis (IE). Cerebrovascular lesions due to NBTE have a distinctive pattern of multiple, widely distributed small and large strokes on brain magnetic resonance imaging (MRI). We present a case of a 78-year-old man who was initially diagnosed as pneumonia and IE; he underwent a trans-esophageal echocardiogram (TEE), which revealed Libman-Sacks findings that have changed his diagnosis to lung cancer. We aim to highlight the characteristic TEE findings of NBTE to help clinicians search for underlying etiologies, including malignancies if NBTE is suspected.
Objective
Although the standard treatment of infective endocarditis (IE) is antimicrobial therapy, surgical intervention is required in some cases. However, the optimal timing of surgery remains unclear. Hence, we conducted a population‐based analysis using the National Inpatient Sample (NIS) database to assess the outcomes of early versus late surgery in patients with native valve IE.
Methods
We queried the NIS database for all hospitalized patients between 2006 and 2016 with a primary diagnosis of IE who had cardiac surgery. We stratified surgery as early ≤7 or late >7 days of admission. Multivariable logistic regression models were used to assess in‐hospital mortality and postoperative complications. Length of stay (LOS) and total hospital cost (HC) were evaluated using multivariable log‐normal regression models.
Results
A total of 13 056 patients (57.6% in the early group and 42.4% in the late group) were included. The in‐hospital mortality rate in the early group was 5.0% compared to 5.4% in the late intervention group (adjusted odds ratio, 1.20, 95% confidence interval [CI] 0.79‐1.81). Overall median LOS was reduced in the early group by 48.2% (95% CI, 46.5%‐49.9%, 12.4 days in the early group and 25.9 days in late group), as well as HC which was reduced in the early group by 28.3% (95% CI, 26.0%‐30.6%).
Conclusion
Among patients with native valve IE who needed cardiac surgery, the time of surgical intervention did not affect the in‐hospital mortality. However, early surgery was associated with significantly shorter LOS and lower HC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
