Long-term follow-up results of lung perfusion studies after transcatheter closure of patent ductus arteriosus.
This study presents the long-term follow-up of patients who developed left lung perfusion (LLP) abnormalities following patent ductus arteriosus (PDA) closure with various device types. ⋯ The LLP abnormalities seen after PDA closure with various devices eventually improve to normal in the majority of patients during long-term follow-up. Patients whose PDA length is shorter than its diameter are at risk of developing LLP abnormalities that persist long-term.

In medical literature, few cases of Rasmussen's aneurysm have been reported until now, and to the best of our knowledge, there has been no description of a case of Rasmussen's aneurysm in childhood. The child described in the case report had a restrictive cardiomyopathy, complicated by pulmonary hypertension, in association with miliary tuberculosis.

Use of a pressure guidewire to assess pulmonary artery band adequacy in the hybrid stage I procedure for high-risk neonates with hypoplastic left heart syndrome and variants.
The hybrid stage I procedure is an alternative palliative strategy for patients with hypoplastic left heart syndrome who traditionally have undergone the Norwood operation. At our institution, the hybrid stage I procedure is employed only for patients with high operative risk. Our objective was to describe our use of a pressure guidewire during the hybrid stage I procedure to assess quantitatively pulmonary artery band adequacy. ⋯ This novel use of a pressure guidewire to assess quantitatively pulmonary artery band adequacy at the time of placement is feasible, safe and may decrease the need for reoperation for pulmonary artery band adjustment.

Predictors of left ventricular remodeling after aortic valve replacement in pediatric patients with isolated aortic regurgitation.
To identify the risk factors that could predict postoperative outcome after aortic valve replacement in pediatric patients with isolated aortic regurgitation (AR). ⋯ In children with AR, preoperative LV dysfunction and extreme LV dilation (>4 SD) are significant predictors of incomplete LV remodeling or persistent LV dysfunction.

Dexmedetomidine: therapeutic use for the termination of reentrant supraventricular tachycardia.
The current drug of choice for reentrant supraventricular tachycardia (SVT) is adenosine followed by verapamil or diltiazem. Although limitations and significant adverse events have been encountered over the years, an alternative effective and safe agent has not been available. Dexmedetomidine has recently been shown to have potential antiarrhythmic effects, and here we describe our experience in the acute termination of reentrant SVT. ⋯ Dexmedetomidine appears to have novel antiarrhythmic properties for the acute termination of reentrant SVT. Although adenosine is very effective, dexmedetomidine may prove to possess a more favorable therapeutic profile with increased effectiveness and fewer side effects.
