Comparative StudyHypothermia and operative mortality during on-pump coronary artery bypass grafting.
Controversy surrounds the effect of hypothermia on operative mortality during cardiac surgery. The present study accessed a large clinical database of coronary artery bypass graft operations to address the issue. ⋯ Most patients receive hypothermia during on-pump coronary artery bypass grafting. Hypothermia is protective against operative mortality compared with normothermia in such patients. Moderate hypothermia does not provide additional survival benefit.

Comparative StudyClinical features of acute aortic dissection from the Registry of Aortic Dissection in China.
To establish a systematic registry of aortic dissection in China, assess the clinical features of Chinese patients with acute aortic dissection (AAD), and compare our results with the data published by the International Registry of Acute Aortic Dissection (IRAD). ⋯ The first Sino-RAD, including 15 large cardiovascular centers throughout China, was established. Our data were compared with those reported by IRAD. We found that, compared with Western populations, Chinese patients with AAD showed 6 differences, including earlier onset, more male patients, a low incidence of hypertension, a low incidence of chest pain, a high incidence of back pain, great differences in the choice of therapeutic strategies, and relatively low in-hospital mortality.

Unidirectional valved patch closure of ventricular septal defects with severe pulmonary arterial hypertension: hemodynamic outcomes.
The purpose of the present study was to study the midterm hemodynamic outcomes of unidirectional valved patch closure of ventricular septal defects (VSDs) in patients with VSD and pulmonary arterial hypertension (PAH). ⋯ Unidirectional valved patch closure of VSD is a promising technique for patients with a large VSD and severe PAH. It had a favorable effect on the immediate, early, and midterm clinical outcomes and hemodynamic parameters.

Multicenter StudyResults of type II hybrid arch repair with zone 0 stent graft deployment for complex aortic arch pathology.
To review the early results of a less invasive, single-stage hybrid arch procedure involving replacement of the ascending aorta, arch debranching, and zone 0 antegrade stent graft deployment. ⋯ This single-stage hybrid arch procedure offers an alternative approach to complex diffuse aortic pathology involving the arch. Replacement of the ascending aorta provides a safe location for zone 0 stent graft deployment, eliminating complications of proximal deployment in a native diseased aorta.

Observational StudyLeft ventricular dysfunction after mitral valve repair--the fallacy of "normal" preoperative myocardial function.
A proportion of patients experience a decrease in left ventricular (LV) ejection fraction (EF) after mitral valve repair; however, predictors and long-term consequences remain unclear. ⋯ De novo postoperative LV dysfunction is not uncommon in patients with "normal" preoperative EF undergoing mitral valve repair. LV dysfunction can persist, impairing recovery of LV size, function, and survival. The consideration of mitral repair before the onset of excessive LV dilation or pulmonary hypertension, even in those with preserved EF, seems warranted.
