Modified Distal Aortic Arch Occlusion During Aortic Arch Replacement.
Circulatory arrest has been identified as an independent risk factor related to postoperative mortality in patients with Stanford type A aortic dissection. This study described a modified technique for distal aortic arch occlusion that markedly shortened the circulatory arrest time. The early results are encouraging. ⋯ A modified distal aortic arch occlusion can considerably shorten the duration of circulatory arrest. Current experience suggests that this approach can serve as a feasible alternative for patients during aortic arch replacement because of its simplicity and satisfactory clinical effects.

Letter ReviewCSANZ Position Statement on COVID-19 From the Paediatric and Congenital Council✰.
At the time of writing (25 May 2020), there have been nearly 4.4 million infections and 300,000 deaths worldwide related to COVID-19, an infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Australia (currently 6,900 infections and 98 deaths) and New Zealand (1,500 infections and 21 deaths) have thus far been less affected than other regions. ⋯ The purposes of this document from the Paediatric and Congenital Council of the Cardiac Society of Australia and New Zealand (CSANZ) are to: 1) To review the mechanisms for cardiac involvement in COVID-19, specifically as they may impact patients with childhood and adult congenital heart disease (CHD); 2) To review the impact of SARS-CoV-2 infection in the paediatric population; 3) To review available data on the risks related to COVID-19 for childhood heart disease and adult CHD; 4) To provide guidance for childhood heart disease and adult CHD units in our Australasian region to re-organise services during the pandemic, so as to protect a highly specialised workforce and yet continue to provide an essential service; and 5) To review risk reduction strategies for acquiring COVID-19 for patients with childhood heart disease or adult CHD. Eleven (11) recommendations relevant to the care of children with heart disease and adults with CHD to mitigate the impact of COVID-19 are highlighted through the document.

Effect of Septal Myectomy on Obstructive Sleep Apnoea Syndrome in Patients With Hypertrophic Obstructive Cardiomyopathy.
The prevalence of obstructive sleep apnoea (OSA) is high in patients with hypertrophic cardiomyopathy. The effect of septal myectomy on OSA is not clear. This study aimed to examine the association between hypertrophic obstructive cardiomyopathy and OSA before and after septal myectomy. ⋯ The severity of OSA significantly increased 3 months after septal myectomy as determined by AHI, obstructive apnoea index, and hypopnoea index. Mean oxygen saturation and time% with SpO2 <90% during sleep before surgery were independently associated with the increase of AHI. However, the specific mechanism of such deterioration of OSA after septal myectomy needs to be determined in detail.

The Experience of Early Extubation After Paediatric Congenital Heart Surgery in a Chinese Hospital.
Early extubation has become widely adopted in cardiac surgery practices. This study aimed to present experience of early extubation after congenital heart surgery and to explore the factors that affect successful immediate postoperative extubation and early extubation. ⋯ Early extubation for children with congenital heart surgery was successful in this hospital. Patients with early extubation had a lower reintubation rate and nasal continuous positive airway pressure rate, and a shorter length of stay in the ICU and hospital. Early extubation was influenced by age, weight at surgery, preoperative pneumonia, CPB type, CPB time, deep hypothermic circulatory arrest, ultrafiltration, and STAT categories.
