Effect of motorized scooters on quality of life and cardiovascular risk.

Physical inactivity increases cardiovascular risk. The possible adverse effects of regular motorized scooter use, recently popularized for patients with physical limitations, has not been previously examined. We performed a single-center, retrospective cohort study of 102 consecutive patients who had obtained medical approval for, and subsequently received, a motorized scooter during a 6-year period.

Effusive constrictive pericarditis: 2D, 3D echocardiography and MRI imaging.

The entity of effusive constrictive pericarditis (ECP) combines clinical and echocardiographic features of pericardial effusion and constrictive pericarditis. We describe a case of ECP, of probable tuberculous etiology, with typical hemodynamic findings of pericardial constriction, which persisted after the pericardial effusion was drained. Thickening of parietal and visceral pericardium was seen on 2D and 3D echo, and on MRI.

A hyperactive pulmonary vasculature in response to chronic mitral regurgitation.

A subset of patients with mitral valve disease has a marked rise in pulmonary vascular resistance (PVR) that is disproportionate to elevations in pulmonary venous pressure. Termed a "hyperactive" pulmonary vasculature, the elevation in PVR falls promptly and dramatically in response to mitral valve replacement. We report a 55-year-old man with progressive, exertional dyspnea of several months' duration who had signs of congestive heart failure (CHF) with moderate mitral valvular regurgitation and aortic stenosis by echocardiographic interrogation.

Late "adult form" scimitar syndrome presenting with "infant form" complications.

This case report describes an 85-year-old woman with complications resulting from scimitar syndrome, anomalous drainage of the right pulmonary veins into the inferior vena cava. In addition to being the oldest reported case of this congenital anomaly, this is the first report of pulmonary vascular complications from scimitar manifested in the adult. The magnitude of the vascular shunt and advanced nature of the disease precluded surgical or percutaneous intervention in this patient.
