Pediatric cardiac interventions: Innovations from India

Dear Sir, It was an enlightening and heartening experience to read through the article on Indian contributions to the field of pediatric interventions[1] published in the July 2024–August 2024 issue of the journal. It must have been a daunting task to collate the entire gamut of innovative interventional contributions from the country and the authors must be congratulated for their comprehensive yet lucid composition of the list. I would like to suggest a few more noteworthy contributions that might merit addition to the already exhaustive list. The first two, although not directly interventional innovations, are innovative additions to the imaging armamentarium that facilitate easy intervention in challenging subsets. Description of the double inversion technique for coronary angiography in situs inversus dextrocardia.[2] Although its utility is more in adults, it has revolutionized the way fluoroscopic images of coronary angiograms are acquired in this instance and paved a way for easy interpretation facilitating interventional therapy in these adults[3] who may be considered as a part of the grown-up congenital heart disease (despite having structurally normal hearts) once they develop coronary artery disease Description of the right anterior oblique (RAO) view for profiling a patent ductus arteriosus that is not visualized well in lateral projection.[4] The utility of this paper is immense as RAO projection has now become the standard second preferred go-to projection of choice once lateral projection is found noncontributory facilitating profiling and crossing the duct during device closure in otherwise elusive ducti, especially in adults and elderly Although the atrial flow regulator device was predominantly designed abroad, since it’s primary design was by an Indian[5] and since the first large study documenting its utility was from an Indian center,[6] probably it should also be a part of the list.
