“…The application of radiofrequency energy for valvar perforation in selected cases of PA and IVS has been employed with good results 3940. The same technology has also been used for vessel recanalisation or trans-septal access to the left atrium in infants 4142. Because of late referrals in South America, PVS is commonly found in adolescents and adults with large pulmonary valve annulus.…”

Congenital heart diseases are one of the most common structural defects present at birth, with an approximate incidence of 8 per 1000 live births. As most countries in South America have a high birth rate, they are a significant public health concern. This paper provides a brief overview of the burden of congenital heart disease in South America, focusing on its local prevalence, facilities for treatment and outcomes after medical, surgical or catheter intervention for the most common diseases.

“…Stent implantation to treat long-standing isolation of a pulmonary artery in older children has been described [18,19]. In our patient, balloon expandable coronary stents were chosen because of their flexibility and low profile, rendering delivery easier and with less-associated risk of thrombosis when crossing the right AD when stenting the pulmonary artery confluence.…”

We present a case of a newborn infant with double inlet left ventricle, pulmonary atresia, confluent pulmonary arteries, and bilateral arterial ducts (AD), to discuss the therapeutic alternatives offered by interventional catheterization techniques in this anatomic arrangement. The infant initially underwent stenting of the right AD to stabilize pulmonary blood flow off of prostaglandin infusion. Three weeks later, she developed left pulmonary artery isolation upon closure of the left arterial duct. An additional stent was placed in the pulmonary artery confluence, restoring blood flow to the left lung and significantly improving her oxygen saturations. At 6 months of age she underwent her first surgical procedure, a successful bidirectional cavopulmonary anastomosis with removal of the left pulmonary artery stent and patch enlargement of the pulmonary artery confluence. She continues to do well in clinical follow-up at 16 months of age.

“…Pediatric patients with chronically occluded 27 or atretic 28 pulmonary arteries have been successfully recanalized following electrosurgical traversal, as has an iatrogenic endograft occlusion of the right pulmonary artery during transcatheter pulmonary valve replacement. 29 Aorto-ostial coronary artery occlusions are challenging due to a lack of antegrade options.…”

Transcatheter electrosurgery describes the ability to cut and traverse tissue, at a distance, without an open surgical field and is possible using either purpose-built or off-the-shelf devices. Tissue traversal requires focused delivery of radiofrequency energy to a guidewire tip. Initially employed to cross atretic pulmonary valves, tissue traversal has enabled transcaval aortic access, recanalization of arterial and venous occlusions, transseptal access, and many other techniques. To cut tissue, the selectively denuded inner curvature of a kinked guidewire (the Flying-V) or a single-loop snare is energized during traction. Adjunctive techniques may complement or enable contemporary transcatheter procedures, whereas myocardial slicing or excision of ectopic masses may offer definitive therapy. In this contemporary review we discuss the principles of transcatheter electrosurgery, and through exemplary clinical applications highlight the range of therapeutic options offered by this versatile family of procedures.
