Observational StudyImpact of coronary total occlusion on graft failure and outcomes of coronary artery bypass grafting.
The study objective was to assess the impact of chronic total occlusion on long-term graft failure and outcomes in patients who underwent coronary artery bypass grafting. ⋯ Chronic total occlusion graft was associated with an increased risk of graft failure. Surgical technique and guideline-directed medical therapy should be noted to improve chronic total occlusion graft patency.

Multicenter StudyPulmonary homograft dysfunction after the Ross procedure using decellularized homografts-a multicenter study.
Pulmonary homograft dysfunction is a limitation after the Ross procedure. Decellularized pulmonary homografts can potentially mitigate this complication. The aim of this study was to examine the incidence, predictors, progression, and morphology of pulmonary homograft dysfunction using data from the Canadian Ross Registry. ⋯ The use of decellularized cryopreserved pulmonary homografts results in a low incidence of dysfunction and reintervention after the Ross procedure. The risk is greater in the first postoperative year. Younger age is the only independent risk factor for pulmonary homograft dysfunction.

The American College of Surgeons Surgical Risk Calculator performs well for pulmonary resection: A validation study.
The American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (NSQIP SRC) was developed to estimate the risk of postoperative morbidity and mortality within 30 days of an operation. We sought to externally evaluate the performance of the NSQIP SRC for patients undergoing pulmonary resection. ⋯ Except for readmission, renal failure, discharge to a location other than home, and sepsis, the NSQIP SRC can be used to reasonably predict postoperative complications in patients undergoing pulmonary resection.

Influence of facility volume on long-term survival of patients undergoing esophagectomy for esophageal cancer.
This study investigated the influence of facility volume on long-term survival in patients with esophageal cancer treated with esophagectomy. ⋯ Esophageal cancer patients treated with esophagectomy at higher volume facilities have significantly better long-term survival than patients treated at lower volume facilities.

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.
