Key result
Coronary microcatheter aligns a perforating guidewire to achieve central pulmonary valve perforation in PA-IVS.
Why the study?
Procedural failures and complications are common in percutaneous perforation of atretic pulmonary valve in PA-IVS, and the created orifice is often eccentric.
Does the use of a coronary microcatheter improve alignment for central perforation of the atretic pulmonary valve in patients with PA-IVS?

Does the use of a coronary microcatheter improve alignment for central perforation of the atretic pulmonary valve in patients with PA-IVS?
Using a coronary microcatheter may facilitate central, rather than eccentric, perforation of the atretic pulmonary valve during percutaneous interventions for PA-IVS.
May facilitate central perforation in PA-IVS interventions; leaves open safety and efficacy in larger series.
Percutaneous perforation of pulmonary valve, using 0.014" guidewires meant for coronary artery chronic total occlusion (CTO), is increasingly being performed for select cases of pulmonary atresia with intact ventricular septum (PA-IVS). Despite growing experience, procedural failures and complications are not uncommon. Even in infants treated successfully, the orifice created in the atretic pulmonary valve is eccentric. In this report, we present usefulness of coronary microcatheter in alignment of perforating coronary guidewire to the center of atretic pulmonary valve resulting in central perforation.

Juneja et al. (2017) conducted a case report in Pulmonary atresia with intact ventricular septum (PA-IVS). Coronary microcatheter was evaluated on Central perforation of atretic pulmonary valve. A coronary microcatheter successfully aligned a perforating coronary guidewire to the center of an atretic pulmonary valve, resulting in central perforation in a patient with PA-IVS.
