Randomized Controlled TrialA comparison of cardiac post-conditioning and remote pre-conditioning in paediatric cardiac surgery.
Remote ischaemic pre-conditioning and cardiac ischaemic post-conditioning provide myocardial protection in cardiac surgery. However, these two endogenous strategies have not been directly compared in a clinical setting. The purpose of this study was to compare the efficacy of remote ischaemic pre-conditioning and post-conditioning in providing myocardial protection to children undergoing cardiopulmonary bypass for surgical repair of ventricular septal defect. ⋯ Our study demonstrates that ischaemic post-conditioning and remote ischaemic pre-conditioning provide comparable myocardial benefit in children undergoing cold blood cardioplegic arrest.

Novel frameshift mutation in Troponin C ( TNNC1) associated with hypertrophic cardiomyopathy and sudden death.
PurposeHypertrophic cardiomyopathy is the most common cause of sudden death in young people, including trained athletes, and is caused by mutations in genes encoding proteins of the cardiac sarcomere. Mutations in the Troponin C gene (TNNC1) are a rare genetic cause of hypertrophic cardiomyopathy. We describe a novel type of mutation (c.363dupG) in Troponin C, a rare form of hypertrophic cardiomyopathy. ⋯ We report the first frameshift mutation (c.363dupG or p.Gln122AlafsX30) in Troponin C causing hypertrophic cardiomyopathy (and sudden cardiac death) in a 19-year-old male, and have demonstrated that the mutation segregates with hypertrophic cardiomyopathy within the family.

Anaesthetic and post-operative management of a modified Norwood operation for hypoplastic left heart syndrome: a retrospective series of 11 cases.
This study aimed to describe the pre-operative and operative findings, as well as the post-operative haemodynamics of patients operated on for hypoplastic left heart. The findings of patients who survived or did not survive were also compared to anticipate the risk factors for mortality. ⋯ The pre-operative, operative, and post-operative findings may be related to mortality early after the modified Norwood operation for hypoplastic left heart syndrome.
