Our study is the second largest series of RPH following cardiac catheterization and predicts female gender, large sheath size, left groin access and low body surface area as risk factors for RPH.
Despite the use of laser technology over the last decade, there are limited data to show its procedural and clinical success in infra-popliteal disease. We hypothesized that laser-assisted balloon angioplasty (LABA) is at least similar or better in procedural and peri-procedural outcomes compared to balloon angioplasty (BA) alone, despite adverse lesion characteristics prior to intervention. Retrospective chart and angiogram review of consecutive critical limb ischemia (CLI) patients who underwent endovascular revascularization in the popliteal or infra-popliteal vessels between 2007 and 2012 with LABA or BA alone. Data from 731 patients revealed that baseline demographics were similar in the LABA (n = 398) and BA group (n = 333) with minor exceptions. More patients in the LABA group had TASC-D lesions (92.5 vs. 66.7 %; P < 0.0001) and chronic total occlusions (CTOs) in both vessel 1 (86.4 vs. 49.5 %; P < 0.0001) and vessel 2 (78.6 vs. 47.8 %; P < 0.0001). Multivariate analysis performed using logistic regression after adjusting for confounding factors showed use of LABA was associated with a 7 times greater likelihood of achieving <50 % residual disease compared to BA alone (OR 7.59, P < 0.0001), and a 5 times greater likelihood of improvement in the infra-popliteal lesion severity score than balloon angioplasty alone (OR 4.77, p < 0.0001). LABA is significantly better at achieving angiographic success and improving lesion severity score in spite of adverse lesion characteristics (more TASC-D lesions and CTOs) compared with BA alone. Our findings suggest that the use of LABA is an endovascular approach that is at least as effective and safe or better compared to BA for the treatment of CLI from complex popliteal and infra-popliteal vascular disease.
Introduction. Brugada syndrome accounts for about 4% of sudden cardiac deaths (SCD). It is characterized by an ST-segment elevation in the right precordial electrocardiogram (EKG) leads.
Case Presentation. We describe a 39-year-old healthy Caucasian man who was admitted to the intensive care unit after being cardioverted from ventricular fibrillation (VF) arrest. His past history was significant for an episode of syncope one month prior to this presentation for which he was admitted to an outlying hospital. EKG during that admission showed ST elevations in V1 and V2 leads, a pattern similar to Type 1 Brugada. A diagnosis of Brugada syndrome was missed and the patient had a cardiac arrest a month later. We discuss a short review of Brugada syndrome and emphasize the need to look for it in patients presenting with SCD and malignant arrhythmias. Conclusion. Physicians should always consider Brugada syndrome in the differential diagnosis of ST-segment elevation in anterior precordial leads of EKG and associated VT/VF. Although more than 17 years have passed since the first case was reported, increased awareness of this syndrome is needed to identify patients with EKG changes and treat them accordingly to prevent incidence of (SCD) and its deleterious complications.
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.
