Prosthetic heart valves and the COVID-19 pandemic era: What should we be concerned about?
Article in Journal of cardiac surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe disturbance in the international normalized ratio (INR) in patients receiving warfarin therapy is of concern. We aimed to evaluate coagulation features in hospitalized patients under warfarin treatment for prosthetic heart valves during the novel coronavirus disease 2019 (COVID-19) pneumonia pandemic.
methodsBetween 20 February and 28 March 2020, 10 patients (7 males) who were under warfarin therapy for prosthetic heart valves were hospitalized after a diagnosis of COVID-19 in Tehran Heart Center, Tehran, Iran. The clinical, paraclinical, and in-hospital outcomes were described. The patients were followed for 4 weeks.
resultsThe median age was 62 years. All the patients received antiviral treatment, either lopinavir/ritonavir or oseltamivir. The serum level of high-sensitivity C-reactive protein ranged between 0.24 and 15.24 mg/dL. Alanine aminotransaminase was normal in all the patients except for two, with levels 1.6 and 4.2 times above normal values. The INR increased in all the patients. One (10%) patient died in the hospital. No bleeding, ischemic, or thrombotic events occurred during the hospital stay and within the 4-week follow-up.
conclusionsAntiviral therapy in patients with COVID-19 with prosthetic heart valves might be an issue responsible for an uncontrolled INR. Liver injury may happen in a minority of patients. Bridging in these patients during the antiviral treatment might be required and because of significant INR fluctuations, it might be safer to prescribe antiviral treatment in an inpatient setting.
