Supravalvar aortic stenosis: clinical and hemodynamic profile, and surgical outcome.
Supravalvar aortic stenosis is the rarest of left ventricular outflow obstructions. Data on this rare entity from India are scarce. ⋯ Repair of supravalvar aortic stenosis by single sinus aortoplasty is safe and produces good results.

Usefulness of intravenous metoprolol during positive isoproterenol tilt-table test in the choice of treatment for neurocardiogenic syncope.
Isoproterenol tilt-table testing provides a diagnosis of neurocardiogenic syncope in patients with syncope or near-syncope. Although acute beta-blockade may prevent the development of syncope during isoproterenol tilt-table testing, the use of beta-blockers for chronic prophylaxis may not be effective for some patients who show a positive response to isoproterenol tilt-table testing. We evaluated whether the efficacy of intravenous metoprolol in preventing symptoms during repeated tests would be helpful in selecting patients suitable for long-term therapy. ⋯ We conclude that acute beta-blockade response to positive isoproterenol tilt-table testing is not a useful predictor for the assessment of chronic prophylaxis for neurocardiogenic syncope.

Utility of N-terminal pro-brain natriuretic peptide for the diagnosis of heart failure.
The goal of this study was to evaluate the utility of plasma N-terminal pro-brain natriuretic peptide for the diagnosis of heart failure in patients presenting with shortness of breath. ⋯ Our results suggest that N-terminal pro-brain natriuretic peptide can be reliably used for the diagnosis of heart failure in an outpatient setting, and this will improve the ability of clinicians to differentiate patients with shortness of breath due to heart failure from those with other causes of shortness of breath.
