Diagnostic Performance of Pulmonary Capacitance at Rest and During Exercise in Idiopathic Pulmonary Arterial Hypertension.
Reliable markers of early disease are needed in pulmonary arterial hypertension (PAH). As measures of the contribution of abnormal vascular compliance to overall vascular resistance, resting and exercise pulmonary capacitance-defined as the stroke volume divided by the change in pulmonary pulse pressure-may be sensitive markers of early disease. ⋯ In idiopathic pulmonary arterial hypertension (IPAH) there is a reduction in pulmonary capacitance at baseline and left-shift of the inverse capacitance-PVR relationship with exercise. Both resting and exercise pulmonary capacitance have potential as diagnostic markers in early disease.

Observational StudyMinimally Invasive Aortic Valve Replacement Via Right Anterior Mini-Thoracotomy: Propensity Matched Initial Experience.
Aortic valve replacement by way of a right anterior mini-thoracotomy (RAMT) has shown excellent results in terms of mortality and morbidity. The aim of the present study was to compare RAMT aortic valve replacement (AVR) with conventional full sternotomy in regards to early perioperative outcomes and mortality. ⋯ Right anterior mini-thoracotomy in patients undergoing isolated aortic valve surgery is a safe approach in select patients, although associated with longer cardiopulmonary bypass times and ICU length of stay.
