For the prevention of recurrent embolic stroke, 23 elderly patients with non-valvular atrial fibrillation (NVAF) were treated with oral anticoagulants (warfarin) during a mean period of 3.8 years. Only one patient suffered recurrent embolism, and another had acute myocardial infarction. There was no cerebral haemorrhage during the treatment. In an untreated control group (from an autopsy series), recurrent embolic strokes occurred in 18 of 70 NVAF patients (26%) during a mean period of 1.3 years. Long-term anticoagulant therapy appears to be effective in the prevention of recurrent embolic stroke in elderly patients with NVAF.
A left-sided lesion of a coronary cameral fistula (CCF) is extremely rare. Surgical closure of the fistula is indicated when symptoms emerge or as a preventive strategy, while surgical approaches depend on the individual anatomical structures. In particular, a CCF forming a "fistula lake" with multiple inflow vessels is so unique that few studies have focused on the technique to close it. We report the successful management of a CCF originating from multiple coronary arteries and draining into the left ventricle via a "fistula lake" by ligation and clipping of associated communication tracts. On the postoperative coronary computed tomography angiography, the fistula lake and the small vessels entering it had all disappeared.
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.
