Reappraisal of cardiac magnetic resonance imaging in idiopathic outflow tract arrhythmias.

INTRODUCTION: Because of prognostic and therapeutic implications, the distinction between idiopathic right ventricular (RV) outflow tract (iRVOT) and arrhythmogenic RV cardiomyopathy (ARVC) is clinically important. Over the last 2 decades multiple reports have identified RV abnormalities using CMR in patients with idiopathic VT, suggesting a link between these arrhythmias and ARVC. The purpose of this study was to assess for structural abnormalities in patients with iRVOT tachycardia using contemporary cardiac magnetic resonance (CMR) imaging. METHODS AND RESULTS: CMR was performed in 46 patients with iRVOT tachycardia and 16 normal controls, with quantitative evaluation of RV and left ventricular volumes and function, as well as assessment of myocardial fat and scar. iRVOT patients were similar to controls with respect to RV end-diastolic volumes (81 ± 19 mL/m(2) vs. 79 ± 18 mL/m(2) , P = 0.77) and RV ejection fraction (57 ± 8% vs. 59 ± 7%, P = 0.31). The prevalence of RV chamber dilation, defined using ARVC major task force criteria, was uncommon among iRVOT patients (9%) and controls (7%; P = 1.0). Regional RV wall motion abnormalities were present in 2 iRVOT patients who had concomitant RV dilation or dysfunction. CMR tissue characterization demonstrated absence of both myocardial scar and fat infiltration in all patients and controls. CONCLUSIONS: In patients with the clinical diagnosis of iRVOT tachycardia, CMR reveals RV structure, function, and myocardial tissue characteristics similar to normal controls. These findings suggest that the vast majority of patients with RVOT arrhythmias have a primary electrical disorder that is not a forme-fruste of ARVC.

"We're Onto Something Here!": Clinician Perspectives of a Pilot Program to Increase Palliative Care Access in an Urban Skilled Nursing Facility.

Many adults cycle between the hospital and skilled nursing facilities (SNFs) near the end of life. However, palliative care services, which can provide specialized support for patients with serious illness, are often limited at SNFs. The "3C's Palliative Care Program," a 5-month pilot, aimed to improve palliative care access for patients admitted to subacute rehabilitation at an SNF affiliated with an urban academic medical center. This manuscript focuses on the pilot's feasibility, acceptability based on SNF clinician feedback from interviews, and lessons learned. The 3C's Program featured primary palliative care skill coaching, virtual palliative care consultations, and continuity via referrals to home-based palliative care at discharge. Ninety percent of SNF clinicians surveyed recommended the continuation of the pilot. SNF clinicians felt the program improved their ability to identify patients for PC consultation, to understand the role and value of palliative care, and to appreciate their patients' illness trajectories. Lessons learned from this pilot suggest SNF-Palliative Care clinician relationship building and simple patient identification mechanisms for palliative care are key to the success of palliative care at SNF integration.

Sleep disorders and fatigue: special issues in the older adult with cancer.

Older adults with cancer reporting fatigue and sleep disorders often have coexisting geriatric syndromes and are at high risk of further functional decline. This review summarizes special considerations in the diagnosis and treatment of sleep disorders and fatigue when older persons with cancer present with multiple comorbidities, polypharmacy, dementia, delirium, and/or falls. Physicians caring for these older adults need to be aware of the unique diagnostic and treatment concerns in this population so that these patients can receive optimal care.
