BACKGROUND We reviewed our experience with congenital ruptured sinus of Valsalva aneurysms (RSVA) to determine risk factors influencing occurrence and postoperative worsening of aortic regurgitation (AR). METHODS Over an 11-year period, 210 patients (33 ± 9.7 years old) underwent surgical repair of RSVA. Aneurysm originated from the right noncoronary(More)
BACKGROUND We reviewed the experience of An Zhen and Fu Wai Hospital for congenital sinus of Valsalva aneurysm (SVA) to determine risk factors for aortic valve replacement (AVR) and postoperative progression of aortic regurgitation (AR). METHODS Over a 7-year period, 255 patients underwent surgical repair of an SVA. Aneurysms originated from the right(More)
BACKGROUND Cardiopulmonary bypass (CPB) has been shown to be associated with a systemic inflammatory response leading to postoperative organ dysfunction. Elucidating the underlying mechanisms and developing protective strategies for the pathophysiological consequences of CPB have been hampered due to the absence of a satisfactory recovery animal model. The(More)
Angiotensin-converting enzyme 2 (ACE2), an ACE homolog, hydrolyzes angiotensin II and opposes its actions, and plays a protective role in the pathogenesis of pulmonary arterial hypertension (PAH). However, the underlying mechanisms involved in the effect of ACE2 on PAH are still uncertain. In this study, we observed the effects of ACE2 activation on(More)
Two cases of asymptomatic double aortic arch with tetralogy of Fallot are reported. One presented with a non-dominant left arch and left-sided descending thoracic aorta and the other with a non-dominant left arch, a right-sided descending thoracic aorta and a patent ductus arteriosus. One-stage operation was performed and both patients were discharged free(More)
BACKGROUND An inflammatory response leading to organ dysfunction and failure continues to be a major problem after injury in many clinical conditions such as sepsis, severe burns, and trauma. It is increasingly recognized that atrial natriuretic peptide (ANP) possesses a broad range of biological activities, including effects on endothelial function and(More)
OBJECTIVES The aim of this study was to evaluate the results following surgeries for the treatment of coarctation of the aorta in Chinese paediatric patients and to compare the surgery outcomes between simple and complex coarctation procedures. METHODS Between January 2006 and December 2011, 107 consecutive paediatric patients with coarctation of the(More)
BACKGROUND Pediatric patients are susceptible to lung injury. Acute lung injury (ALI) in children often results in a high mortality. Partial liquid ventilation (PLV) has been shown to markedly improve oxygenation and reduce histologic evidence of injury in a number of lung injury models. This study aimed to examine the hypothesis that PLV would attenuate(More)
BACKGROUND/AIMS Renal ischemia/reperfusion injury (IRI) is a very common clinical event and usually leads to ischemic acute renal failure (ARF). In the present study, we investigated the protective role of vitamin C in renal function and renal arterial relaxation following ischemic injury. METHODS IRI model in mice was used. Various biochemical parameters(More)
BACKGROUND Cyanotic patients have potential growth retardation and malnutrition due to hypoxemia and other reasons. Ghrelin is a novel endogenous growth hormone secretagogue that has effects on growth and cardiovascular activities. The aim of this study was to evaluate the plasma level and myocardial expression of ghrelin and insulin-like growth factor-1(More)
