Coronary artery spasm has been reported during adenosine stress testing. Herein, we describe a transient ST-segment elevation following adenosine therapy for supraventricular tachycardia. A 38-year-old male presented to the emergency department with palpitations. Electrocardiogram showed supraventricular tachycardia with short RP interval. Vagal maneuvers(More)
Prosthetic valve obstruction (PVO) is a rare but feared complication of mechanical valve replacement. Diagnostic evaluation should focus on differentiating prosthetic valve thrombosis (PVT) from pannus formation, as their treatment options differ. History of sub-optimal anti-coagulation and post-op time course to development of PVO are useful clinical(More)
A 21-year-old woman in the 16th week of pregnancy was admitted due to acute presentation of severe exertional dyspnea. She had undergone mitral valve replacement (MVR) with bioprosthetic valve for infective endocarditis 2 years ago. She developed congestive heart failure from mitral bioprosthetic valve stenosis due to early structural valve deterioration.(More)
Central diabetes insipidus (CDI) is characterized clinically by the presence of polyuria with the subsequent development of volume depletion and hypernatremia. In patients with dialysis-dependent end-stage renal disease (ESRD), neither of these findings can be expressed due to the absence of renal function. A 59-year-old woman with anuric ESRD of unknown(More)

BACKGROUND Prior studies have demonstrated endothelial and smooth muscle brachial artery dysfunction after transradial cardiac catheterization for diagnostic coronary angiography. The duration of this vascular dysfunction is unknown. OBJECTIVE To determine the time-course of endothelial and smooth muscle cell dysfunction in the upstream brachial artery(More)
