RESUMO
The optimal duration of anticoagulation in patients with left ventricular thrombus (LVT) is unknown. The data package herein presented contains the information used to assess the effect of duration of anticoagulation in the incidence of stroke in patients with left ventricular thrombus (LVT) in a tertiary hospital. In order to collect the required data, all transthoracic echocardiography studies at our institution from January 1st 2014 to December 31st 2021 with LVT were retrieved using dedicated software (Phillips Intellispace Cardiovascular; Koninklijke Phillips N.V., 2004-2020). Second, a dataset was designed ad hoc for this study in which the recruited data for the predefined objectives were obtained from electronic medical records. These data included clinical and demographic information including treatment choices (vitamin K antagonists [VKA] versus direct oral anticoagulants [DOAC]), duration of treatment, reason for interruption of treatment, occurrence of stroke, acute myocardial infarction, bleeding events, thrombus resolution, recurrence, and death. Retrieved data were stored in an excel sheet for analysis using the statistical package STATA (StataCorp v. 15.0, College station, TX). This methodology allows the reuse of these data for further analysis, in the context of the present study and also for future recruitment of additional patients from other institutions to increase statistical power.

The optimal duration of anticoagulation in patients with left-ventricular thrombus (LVT) is unclear. In the present study, we aimed to analyze the effect of treatment duration (≤12 months [short-term anticoagulation, (STA)] versus >12 months [long-term anticoagulation, (LTA)]) in the incidence of stroke and other secondary outcomes (acute myocardial infarction, bleeding, and mortality). Multivariate Cox regression was used to determine the association between treatment duration and stroke, adjusted for baseline embolic risk. A total of 98 cases of LVT (age 64.3 ± 12.8 years, female 18 [18%]) were identified. Sixty-one patients (62%) received LTA. Patients receiving LTA were older than those receiving STA (66.5 ± 11.6 vs 60.7 ± 13.9 years, p = 0.029), more often had atrial fibrillation (31% vs 0%, p <0.001), and had a higher CHA2DS2-VASc score (4.3 ± 1.6 vs 3.6 ± 1.6, p = 0.046). Stroke occurred in 2 and 10 patients (3% vs 27%, p <0.001), acute myocardial infarction in 2 and 3 patients (3% vs 8%, p = 0.292), bleeding in 4 and 3 patients (7% vs 8%, p = 0.773), and mortality in 12 and 7 patients (20% vs 19%, p = 0.927) in the LTA and STA groups, respectively. In multivariate analysis, after adjusting for embolic risk, LTA was associated with decreased risk of stroke at 5 years (adjusted hazard ratio 0.16; 95% confidence interval 0.03 to 0.72, p = 0.017). In conclusion, our data suggest that prolonged anticoagulation in patients with LVT may be associated with significantly lower risk of stroke.

Immune checkpoint inhibitors are associated with a myriad of autoimmune adverse events. We present a 70-year-old patient with renal-cell carcinoma treated with nivolumab/ipilimumab complicated with myocarditis and encephalitis in which gradual impairment of the His-Purkinje system progressed to complete atrioventricular block. Full recovery was achieved after treatment with corticosteroids and immunoglobulins. (Level of Difficulty: Intermediate.).
