Recurrent bilateral lower limb arterial embolism secondary to left ventricular thrombus in peripartum cardiomyopathy successfully treated with systemic streptokinase thrombolysis: a rare case report.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPeripartum cardiomyopathy (PPCM) is an uncommon but potentially life-threatening form of heart failure occurring toward the end of pregnancy or during the months following delivery in women without pre-existing heart disease. Left ventricular systolic dysfunction predisposes patients to intracardiac thrombus formation and systemic thromboembolic complications, which are associated with significant morbidity and mortality. CASE PRESENTATION: A 35-year-old multiparous woman presented shortly after spontaneous vaginal delivery of an intrauterine fetal demise with acute right lower-limb ischemia and heart failure. Transthoracic echocardiography demonstrated severe left ventricular systolic dysfunction (LVEF approximately 35%), severe functional mitral regurgitation, pulmonary hypertension, and a large left ventricular thrombus. She underwent urgent Fogarty embolectomy followed by therapeutic anticoagulation with unfractionated heparin and warfarin. Despite therapeutic anticoagulation (INR 2.0 and activated partial thromboplastin time approximately 90 seconds), she developed recurrent bilateral acute lower-limb ischemia five days later. Because of profound hemodynamic instability and prohibitive surgical risk, systemic streptokinase thrombolysis was administered. Repeat echocardiography performed immediately after thrombolysis demonstrated complete resolution of the left ventricular thrombus. Follow-up echocardiography one week later showed significant recovery of left ventricular systolic function (LVEF 45-50%), improvement of mitral regurgitation to mild-to-moderate, and reduction in pulmonary artery systolic pressure.
conclusionThis case highlights the importance of early recognition of thromboembolic complications in PPCM and demonstrates that systemic streptokinase thrombolysis may represent an effective life- and limb-saving therapeutic option in carefully selected patients when surgical or catheter-based interventions are not feasible.
