Left ventricular mural thrombi with multisystem thrombosis in patients with COVID-19 and myocardial injury: a case series.

Background: Cardiovascular and thromboembolic complications have been reported in patients with Coronavirus disease-2019 (COVID-19)-related severe respiratory distress syndrome. Although myocarditis associated with COVID-19 pneumonia has been described, evidence of left ventricular (LV) mural thrombi with other multisystem events has not been reported.

Case Summary: We report two cases with severe COVID-19 pneumonia and myocardial injury with large LV thrombi and other multisystem thrombotic events.

Cocaine-induced coronary thrombosis: what is the optimal treatment strategy.

Arterial thrombosis and especially coronary thrombosis are known complications of cocaine abuse. We report three cases of severe life-threatening coronary arterial thrombosis manifesting as acute coronary syndromes. Thrombosis occurred predominantly in the proximal coronary tree with spontaneous distal embolization.
