Late outcomes of surgical reconstruction of peripheral pulmonary arteries.
The ideal management of peripheral pulmonary artery stenosis is still controversial. We adopted a primary surgical approach to this complex lesion with excellent early outcomes. In this study, we analyzed our late outcomes. ⋯ Late outcomes of surgical reconstruction of peripheral pulmonary arteries are excellent and durable in various pathologies (syndromic and nonsyndromic) with a significant reduction in right ventricular to aortic systolic pressure ratio, low mortality, and no reintervention.

American Association for Thoracic Surgery Summer Intern Scholarship-Over a decade of experience.
The study objective was to evaluate the experience of previous American Association for Thoracic Surgery Summer Intern Scholarship recipients. ⋯ The awardees of the American Association for Thoracic Surgery Summer Intern Scholarship come from a variety of medical schools and visited a diverse group of sponsoring institutions. The 8-week program provides valuable early exposure for medical students to cardiothoracic surgeons, the operating room, and research opportunities. This experience was highly recommended by prior recipients to medical students interested in cardiothoracic surgery.

Influence of right ventricular pressure and volume overload on right and left ventricular diastolic function.
Ventricular interdependence may account for altered ventricular mechanics in congenital heart disease. The present study aimed to identify differences in load-dependent right ventricular (RV)-left ventricular (LV) interactions in porcine models of pulmonary stenosis (PS) and pulmonary insufficiency (PI) by invasive admittance-derived hemodynamics in conjunction with noninvasive cardiovascular magnetic resonance (CMR). ⋯ The LV exhibits systolic dysfunction and noncompliance with PI. PS is associated with preserved LV systolic function and evidence of some LV diastolic dysfunction. Interventricular interactions influence LV filling and likely account for differential effects of RV pressure and volume overload on LV function.
