Ascending venous arterialization can be applied for limb salvage to the patients who do not have a suitable arterial bed to revascularize with conventional techniques.
Background:The deterioration of left atrial and ventricular functions was demonstrated in patients with frequent ventricular extrasystole (fVES). The exact pathophysiology of left atrial dysfunction in patients with fVES is unclear. Retrograde ventriculoatrial conduction (VAC) often accompanies fVES, which may contribute to atrial dysfunction. We investigated whether atrial electromechanical delay and VAC are related to these atrial functions in patients with frequent right ventricular outflow tract (RVOT) VES and preserved ejection fraction (pEF).
Methods:This study included 21 patients with pEF (eight males, 48 ± 11 years), who had experienced more than 10 000 RVOT-VES during 24-h Holter monitoring and had undergone electrophysiological study/ablation. The study also included 20 healthy age-and sex-matched control subjects. Transthoracic echocardiography was performed on all of the subjects. Atrial conduction time was obtained by using tissue Doppler imaging. Strain analysis was performed with two-dimensional speckle tracking echocardiography.
Results:The peak atrial longitudinal strain was significantly impaired in patients with fVES (P = 0.01). In addition, although the interatrial and left atrial conduction delay times were significantly different between each group (P < 0.001, P < 0.001), the right atrial conduction delay times were similar. When patients with fVES were divided into groups depending on the existence of retrograde VAC, atrial deformation parameters and conduction delay time did not significantly differ between either group.Conclusion: Frequent RVOT-VES causes left atrial dysfunction. This information is obtained through strain analyses and recordings of left atrial conduction times in patients with pEF. Regardless, retrograde VAC is not related to atrial dysfunction.

The clinicopathologic findings of the third case of androgenic adult granulosa cell tumor in patients younger than 15 years was presented and discussed in the light of the literature. A patient complaining of secondary amenorrhea and hirsutism with elevated levels of plasma total testosterone, dehydroepiandrosterone sulfate, free androgen index and serum inhibin A, and a left ovarian septated, cystic mass was admitted to the hospital. The inhibin A level was within normal levels in the first month postoperatively. Inhibin A could be a tumor marker of utmost importance particularly in patients with androgenic or hyperestrogenic symptoms, especially in cases where benign criteria are abundant such as young age, nonincreased levels of classic tumor markers, and ultrasonographic appearance without any suspicion of malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
