Sarcoidosis is a multisystem, granulomatous disease of unknown etiology often seen in young adults, with cardiac involvement in more than one-quarter of sarcoid patients. The clinical presentation of cardiac sarcoid depends upon the location and extent of myocardium involved. Although cardiac sarcoid may produce asymmetrical septal hypertrophy, it is most commonly considered in the differential diagnosis of dilated cardiomyopathy. The hypertrophic stage of cardiac sarcoid is rarely seen. We describe a case of cardiac sarcoid in a young patient wherein a distinctive appearance of the cardiac sarcoid spectrum from "hypertrophic" stage to thinned/scarred stage, masquerading as hypertrophic cardiomyopathy followed by dilated cardiomyopathy, is demonstrated.
Background: This study explores novel preimplantation risk factors associated with gastrointestinal bleeding (GIB) after continuous-flow left ventricular assist device (CF-LVAD) implantation. CF-LVAD therapy implantation for patients with advanced heart failure is associated with a 20% to 40% incidence of GIB.Methods: This study includes patients receiving CF-LVAD at a quaternary medical center from 2006 to 2014 (n = 254). The primary endpoint was GIB within 12 months after implantation; the secondary outcome was 3-year all-cause mortality. The Student t test or the χ 2 test compared continuous or categorical variables. Competing risks analysis calculated the cumulative incidence of GIB postimplantation. Cox proportional hazards model was used for univariate/multivariate models predicting GIB.Results: Sixty-four patients had GIB, with incidence rates at 1, 3, and 12 months of 11.8%, 19.3%, and 25.2%, respectively. Endoscopy revealed no identified source of bleeding in 41%; 33% of lesions were localized in the upper gastrointestinal tract, with the bulk (39%) categorized as vascular. Patients with prior gastrointestinal abnormalities (n = 98) had a greater risk of GIB post-CF-LVAD (HR 1.85 [1.11-3.09]; P = 0.02) than those with normal gastrointestinal evaluation results (n = 45) and those without preimplantation gastrointestinal evaluation (n = 111). Baseline blood urea nitrogen, chronic obstructive pulmonary disease, and prior percutaneous coronary intervention were statistically associated with post-CF-LVAD GIB. The presence of GIB within 12 months of CF-LVAD implantation was associated with an increased risk of 3-year all-cause mortality ; P < 0.01).
Conclusions:First-year GIB is associated with increased mortality post-CF-LVAD. We advocate a closer examination of several GIB risk factors when evaluating CF-LVAD candidates.
This report describes the ability of cardiac magnetic resonance (MR) imaging to depict an unusual cardiac defect. A type of ventricular septal defect called the Gerbode defect, which results in a communication between the left ventricle and the right atrium, is presented. To the authors' knowledge, this is the first time cardiac MR imaging has been utilized to characterize this defect.
Left ventricular assist devices (LVADs) have dramatically improved short-term outcomes among patients with advanced heart failure. While neurohormonal blockade (NHB) is the cornerstone of treatment for patients with heart failure with reduced ejection fraction, its effect after LVAD placement has not been established. We reviewed medical records of 307 patients who underwent primary LVAD implantation from January 2006 to September 2015 at two institutions in the United States. Patients were followed for at least 2 years post-LVAD implantation or until explantation, heart transplantation, or death. Cox regression analysis stratifying on center was used to assess associations with mortality. Neurohormonal blockade use was treated as a time-dependent predictor. Stepwise selection indicated treatment with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs/ARBs) (hazard ratio [HR] = 0.53 [0.30–0.95], p = 0.03), age at the time of implantation (HR = 1.28 [1.05–1.56] per decade, p = 0.02), length of stay postimplantation (HR = 1.16 [1.11–1.21] per week, p < 0.01) and INTERMACS profile of 1 or 2 (HR = 1.86 [1.17–2.97], p < 0.01) were independent predictors of mortality. In this large, retrospective study, treatment with ACEIs or ARBs was an independent factor associated with decreased mortality post-LVAD placement.
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.
