An interesting case of nonobstructive lower pole hydronephrosis associated with reflux and simulating a neoplasm is presented and discussed. Advanced hydronephrosis localized to one portion of a duplicated kidney in adults may simulate a renal neoplasm on intravenous pyelogram. Upper pole hydronephrosis is a well-described clinical entity and is prominent in the differential diagnosis of renal ...

Background Alterations in systolic blood flow are a characteristic finding in patients with obstructive hypertrophic cardiomyopathy (HCM). Echocardiography is the gold standard for hemodynamic assessment in HCM, but this technique is generally limited to measurement of the left ventricular outflow tract (LVOT) pressure gradient and may not provide a complete description of the hemodynamic impac...

A 76-year-old woman underwent left heart catheterization and coronary angiography for a non–ST-segment elevation myocardial infarction. A transradial approach with an Optitorque Tiger (Terumo, Somerset, New Jersey) catheter was used. Angiography was significant for only moderate nonobstructive disease in the right coronary artery. The Tiger catheter crossed the aortic valve and was used to obta...

A 71-year-old female who was diagnosed with nonobstructive hypertrophic cardiomyopathy since 1999 presented with dyspnea and severe edema on both legs. For the management of her symptom, cardiac surgery including tricuspid annuloplasty, Maze operation and right atrial reduction plasty was performed. During follow-up after cardiac surgery, a plasma α-galactosidase activity was checked for the sc...

A 22 year-old male patient was admitted with supracardiac, nonobstructive, total anomalous pulmonary venous connection and large atrial septal defect. Cardiac catheterization revealed severe pulmonary hypertension due to pulmonary overflow (Qp/Qs 6, pulmonary vascular resistance = 1.6 Woods/m(2)). Complete repair was performed through median sternotomy and cardiopulmonary bypass. The patient wa...
