Prospective assessment of multiple cardiac papillary fibroelastomas: an echocardiographic and surgical study.
Multiple cardiac papillary fibroelastomas (PFEs) are thought to account for less than 10% of patients with PFE. We aimed at evaluating the frequency and location of multiple PFEs and the reliability of transthoracic (TTE) and transoesophageal (TEE) echocardiography in diagnosing multiple PFEs. Twenty-six consecutive patients (52±14 years, 65% males) with pathologically confirmed PFE had 21 PFEs diagnosed by TTE, 33 by TEE, and 62 at surgery. ⋯ Aortic valve was involved in 75% of patients with multiple PFEs and left ventricle in 38% of patients. The sensitivity of TTE in diagnosing any PFEs was 51.3% and 76.9% for TEE. Our study emphasizes the high frequency of multiple PFEs, the need of TEE for all presumed PFE and the need for careful assessment of left-sided endocardial surfaces, especially of the aortic valve, during PFE excision.

BNP at discharge in acute heart failure patients: is it all about volemia? A study using impedance cardiography to assess fluid and hemodynamic status.
Besides hemodynamic parameters, several other variables have been associated to B-type natriuretic peptide (BNP) levels. Limited knowledge on BNP determinants in acute heart failure (HF) can undermine the interpretation of BNP levels. ⋯ Discharge BNP levels in acute HF patients reflected volemia and disease severity. Persistently high BNP levels during hospitalization should raise the possibility of remaining congestion, which could negatively influence prognosis. The utility of BNP as prognostic marker in HF may reside on its ability to reflect multiple underlying pathophysiological disturbances.

Aminoterminal propeptide of type III procollagen (PIIINP) is associated with ascending aortic aneurysm growth rate.
Plasma levels of PIIINP a marker of extracellular matrix metabolism activity have been linked to abdominal aortic aneurysm growth rate, but its relationship with thoracic aortic aneurysm (TAA) growth has never previously been studied. ⋯ Our results suggest that it may in the future be possible to monitor TAA growth by means of PIIINP levels.

The aim of this study was to investigate preoperative clinical and echocardiographic characteristics and N-terminal pro-B type natriuretic peptide (NT-proBNP) levels as prognostic factors for regression of the left ventricular (LV) mass after valvular surgery in patients with chronic severe mitral regurgitation (MR). ⋯ A lower preoperative NT-proBNP level predicted the regression of LV mass after valvular surgery in patients with chronic severe MR. This measure could be used as a biomarker for predicting the postoperative course in such patients.

Metal-induced allergic reactions are not rare in every day practice but nickel, cobalt and chromium are the most common offenders. Other metal anions and metal alloys represent also emerging causes for hypersensitivity reaction in humans. ⋯ Newer intracoronary stents avoid nickel thus making them less allergenic. It is advisable that, before any device implantation, careful history of any metal allergy should be taken and efforts should be made for the development of new devices with better biocompatibility.
