RESUMEN
The pulmonary valve is the least affected site for valvular papillary fibroelastoma. With increasing use of routine echocardiography and other modalities of imaging, pulmonary valve papillary fibroelastomas (PVPFE) are being recognized more frequently. PVPFE is more often an incidental diagnosis and symptomatic patients usually present with shortness of breath. Embolic phenomena and right ventricular outflow tract obstruction are the most serious complications of PVPFE. Since PVPFE is rare, the purpose of this systematic review is to address demographic characteristics, the clinical presentation, management, and outcome of this benign tumor of the pulmonary valve.

OBJECTIVE: To review efficacy of percutaneous closure of patent foramen ovale compared with medical therapy in prevention of recurrent strokes in patients with cryptogenic stroke. METHODS AND RESULTS: Electronic databases; PUBMED, EMBASE, Cochrane registry and web of knowledge were searched for relevant studies. In three randomised clinical trials involving 2303 participants, risk of the recurrent strokes (pooled HR 0.62, 95% CI=0.36-1.07, P=0.09, I(2) =10%) did not show benefit with device closure when compared with medical therapy group on meta-analysis of all three trials. However, on sensitivity analysis in trials using Amplatzer PFO occluder device, the closure of PFO was associated with significantly lower recurrent strokes (pooled HR=0.44, 95% CI=0.21-0.94, P=0.03, I(2)=0%) compared with medical therapy. CONCLUSION: The closure of PFO with Amplatzer PFO occluder device was associated with significant reduction in recurrent strokes in patients with cryptogenic stroke and patent foramen ovale. The better outcome in prevention of secondary stroke in patients with cryptogenic stroke and PFO may be associated with type of closure device used.
