Early Impact of the COVID-19 Pandemic on Congenital Heart Surgery Programs Across the World: Assessment by a Global Multi-Societal Consortium.

The coronavirus disease 2019 (COVID-19) pandemic currently gripping the globe is impacting the entire health care system with rapidly escalating morbidities and mortality. Although the infectious risk to the pediatric population appears low, the effects on children with congenital heart disease (CHD) remain poorly understood. The closure of congenital heart surgery programs worldwide to address the growing number of infected individuals could have an unintended impact on future health for COVID-19-negative patients with CHD. Pediatric and congenital heart surgeons, given their small numbers and close relationships, are uniquely positioned to collectively assess the impact of the pandemic on surgical practice and care of children with CHD. We present the results of an international survey sent to pediatric and congenital heart surgeons characterizing the early impact of COVID-19 on the care of patients with CHD.

The World Society for Pediatric and Congenital Heart Surgery: its mission and history.

The World Society for Pediatric and Congenital Heart Surgery (WSPCHS) was established in 2006 to assemble pediatric and congenital heart surgeons from all continents and regions of the world and their colleagues from related specialties dealing with pediatric and congenital heart disease. Since its birth, it has held a highly successful inaugural scientific meeting in 2007 in Washington, DC, and a World Summit on Pediatric and Congenital Heart Surgery Services, Education, and Cardiac Care for Children and Adults with Congenital Heart Disease in 2008 in Montreal. It currently has 549 members from 71 countries and in a short period of time has become the largest organization in the world of pediatric and congenital heart surgeons. Its brief history already seems to be a guarantee of a promising future. Projects in the areas of research, training and education, patient care, and community service will allow the Society to reach its goals. By bringing together professionals from every region of the world, the WSPCHS should play a significant role in the improvement of care for children and adults with congenital heart disease around the world.

Long-term assessment of mitral valve reconstruction with resection of the leaflets: triangular and quadrangular resection.

BACKGROUND: The procedure of quadrangular resection and suture for prolapsed posterior leaflet of the mitral valve is a reliable and reproducible method that achieves excellent long-term results. However, triangular resection and suture of a prolapsed anterior leaflet is not widely supported and different techniques have been advocated. The aim of this study was to review our experience of mitral valve repair in which resection of the anterior and/or posterior leaflets was performed. METHODS: Between October 1991 and September 2003, 105 patients with mitral regurgitation underwent mitral valve reconstruction with leaflet resection, including 55 patients with quadrangular resection of the posterior leaflet (P), 32 patients with triangular resection of the anterior leaflet (A), and 18 patients with resection of both leaflets (A+P). RESULTS: The mean follow-up period was 63.6 (1 to 139) months. Reoperation was required in 2 patients, each after resection of the anterior or posterior leaflet. The freedom from reoperation rates at 10 years in 93% +/- 5% of patients after triangular resection of the anterior leaflet, 96% +/- 3% after quadrangular resection of the posterior leaflet, and 100% after resection of both leaflets. There were no significant differences of survival or risk of reoperation among these three groups. The postoperative mitral valve area was significantly smaller than the preoperative area in all three groups, but remained large enough (A: 2.84 +/- 1.07; P: 2.6 +/- 0.87; A+P: 3.09 +/- 1.20 cm2) for adequate valve function. CONCLUSIONS: Triangular resection of a prolapsed anterior mitral leaflet is a reliable, reproducible, and durable procedure, like quadrangular resection of a prolapsed posterior leaflet.
