Clinical Features and Sites of Ablation for Patients With Incessant Supraventricular Tachycardia From Concealed Nodofascicular and Nodoventricular Tachycardias.

Objectives: This study sought to describe the clinical features and sites of successful ablation for incessant nodofascicular (NF) and nodoventricular (NV) tachycardias.

Background: Incessant supraventricular tachycardias have been associated with tachycardia-induced cardiomyopathies and have been previously attributed to permanent junctional reciprocating tachycardias, atrial tachycardias, and atrioventricular nodal re-entrant tachycardias. Incessant concealed NF and NV tachycardias have not been described previously.

Metabolomic Profiling in Relation to New-Onset Atrial Fibrillation (from the Framingham Heart Study).

Previous studies have shown several metabolic biomarkers to be associated with prevalent and incident atrial fibrillation (AF), but the results have not been replicated. We investigated metabolite profiles of 2,458 European ancestry participants from the Framingham Heart Study without AF at the index examination and followed them for 10 years for new-onset AF. Amino acids, organic acids, lipids, and other plasma metabolites were profiled by liquid chromatography-tandem mass spectrometry using fasting plasma samples.

Medication adherence and heart failure.

Heart failure remains among the most prevalent and burdensome medical conditions in the United States. With increasing awareness regarding resource use and costs of care, there has been significant interest in the identification of factors that influence rates of hospitalization and readmission in individuals with heart failure. Medication adherence has been identified as one such modifiable factor.

Primary cardiac angiosarcoma: A diagnostic challenge in a young man with recurrent pericardial effusions.

Cardiac angiosarcomas are rare, rapidly progressive tumours that often present as diagnostic dilemmas resulting in delayed diagnosis. They should be considered in patients with recurrent pericardial effusions.A 33-year-old man presented for evaluation of a recurrent pericardial effusion.

Ischemic complications after endovascular abdominal aortic aneurysm repair.

Objectives: Limb and pelvic ischemia are known complications after endovascular abdominal aortic aneurysm repair (EVAR). The objective of this paper is to present our experience with the incidence, presentation, and management of such complications.

Methods: Over 9 years 311 patients with aortic aneurysms underwent EVAR.

Predictors of severe morbidity and death after elective abdominal aortic aneurysmectomy in patients with chronic obstructive pulmonary disease.

Objective: This study sought to identify risk factors associated with an unfavorable outcome after elective abdominal aortic aneurysm (AAA) repair in patients with chronic obstructive pulmonary disease (COPD).

Methods: The clinical records of 158 patients who underwent elective open AAA repair with COPD determined from preadmission International Classification of Diseases-ninth revision codes during a 12-year period at the University of Michigan were reviewed. Patients with uncomplicated outcomes (group I) were compared with those with unfavorable postoperative outcomes (group II).
