Off-label uses of the Amplatzer Piccolo Occluder in children with congenital and acquired heart diseases

Aim: The Amplatzer Piccolo Occluder (APO) is approved for patent ductus arteriosus (PDA) occlusion in infants weighing >700 g but could offer versatility to treat other lesions.Methods: Retrospective review of children in whom APO was utilized for defects other than PDA between January 2022 and June 2023.Results: The APO was used in nine patients; three for ventricular septal defects, four with coronary fistulas, one for a ventricular pseudoaneurysm and one where APO deployed within a fenestration of a previously placed Amplatzer Septal Occluder. All nine patients had successful occlusions without complications.Conclusion: The APO is a versatile device that can be used to treat various small diameter lesions in children besides the PDA for which it is currently approved for.

Capacity changes in German certified chest pain units during COVID-19 outbreak response

Background

We sought to determine structure and changes in organisation and bed capacities of certified German chest pain units (CPU) in response to the emergency plan set-up as a response to the SARS-CoV-2 pandemic.

Methods and results

The study was conducted in the form of a standardised telephone interview survey in certified German CPUs. Analyses comprised the overall setting of the CPU, bed capacities, possibilities for ventilation, possible changes in organisation and resources, chest pain patient admittance, overall availability of CPUs and bail-out strategies. The response rate was 91%. Nationwide, CPU bed capacities decreased by 3% in the early phase of COVID-19 pandemic response, exhibiting differences within and between the federal states. Pre-pandemic and pandemic bed capacities stayed below 1 CPU bed per 50,000 inhabitants. 97% of CPUs were affected by internal reorganisation pandemic plans at variable extent. While we observed a decrease of CPU beds within an emergency room (ER) set-up and on intermediate care units (ICU), beds in units being separated from ER and ICU were even increased in numbers.

Conclusions

Certified German CPUs are able to maintain adequate coverage for chest pain patients in COVID-19 pandemic despite structural changes. However, at this time, it appears important to add operating procedures during pandemic outbreaks to the certification criteria of forthcoming guidelines either at the individual CPU level or more centrally steered by the German Cardiac Society or the European Society of Cardiology.
