We performed a second puncture of the extracardiac conduit in an 11-year-old Fontan patient to assess the patency of the stent previously deployed in the left pulmonary vein. For the first puncture, a mechanical Brockenbrough needle was selected to puncture the Gore-Tex conduit, an electrical insulator. For the second puncture, the location of that previous hole was detected as an indentation covered with atrial tissue, which is an electrical conductor. The second puncture was performed safely using a radiofrequency transseptal needle.

Isoproterenol Infusion

A chronically implanted inflatable balloon was used to produce distension of a left pulmonary vein at its junction with the left atrium in trained conscious dogs. Balloon inflation caused a fall in the amounts of water drunk in response to injection of isoproterenol, infusion of hypertonic NaCl, or overnight water deprivation. There was also a significant increase in heart rate, but arterial, central venous, and left atrial pressures were unaltered. Blockade of the left vagosympathetic nerve prevented the inhibitory action of distension of a pulmonary vein on water intake in response to injection of isoproterenol. In experiments where the balloon was left inflated for 24 h, distension also caused a fall in the spontaneous daily water intake, whereas food intake was unaffected. Despite the fall in water intake, urine flow increased so that the dog went into negative fluid balance. In conclusion, distension of a pulmonary vein at its junction with the left atrium causes reduction in both spontaneous and induced water intake, and this inhibition is not secondary to circulatory changes or fluid retention by the kidney. The action of the receptors concerned may complement the actions of the same or similar receptors on renal function whose effects have been observed previously in acute experiments in anesthetized animals and here for the first time in conscious animals.

A 38-year-old female with tricuspid atresia and normally related great arteries, initially palliated with Björk modified Fontan, and ultimately converted to extracardiac conduit Fontan, with a history of ventricular tachycardia and hepatitis C virus (HCV) treated with sofosbuvir/ledipasvir, was referred to our center for consideration of combined heart and liver transplantation. The patient’s blood group was O with panel reactive antibodies of 52%. She consented to consideration of HCV-positive donors. Fifteen days later, an HCV-positive donor was identified, and she underwent heart transplantation with pulmonary artery reconstruction performed jointly by adult and pediatric transplant surgeons. To our knowledge, this the first time an HCV-positive donor heart has been to transplant an adult with congenital heart disease.

Pulmonary arteriovenous fistula is a rare disease. To the best of our knowledge, prenatal diagnosis of a fistula between the left pulmonary artery and the left pulmonary vein has not been described in the medical literature. We report a case of the prenatal diagnosis of a left pulmonary artery-to-pulmonary vein fistula, followed by successful neonatal surgical repair.

Abstract Introduction Catheter ablation of perimitral flutter can be challenging, owing to difficult anatomy. The most commonly applied procedure is the creation of a mitral isthmus line (between the lower left pulmonary vein and the mitral anulus) or an anteroseptal line (between the upper right pulmonary vein and the anterior mitral anulus). Purpose Our study aimed to compare the short and long term efficacy of two different ablation methods. Methods In our retrospective study 45 consecutive patients diagnosed with perimitral flutter were included between 2009 and 2018. Results Radiofrequency ablation was performed in 48 cases in 31 patients (mitral isthmus line (n = 25, 52.1%); anteroseptal line (n = 23, 47.9%)). Arrhythmia-termination and sinus rhythm restoration could be achieved in 64.6% of the cases (mitral isthmus line: 16/25 (64.0%), anteroseptal line: 15/23 (65.2%). Comparing two different techniques, there was no significant difference (p = 0.85) in acute success rates. During 24.3 months of follow-up period, in 60.0% of the patients no recurrence occurred. The arrhythmia recurred in 6 cases (40.0%) after anteroseptal line ablation, and in 8 cases (53.3%) after mitral isthmus line ablation. No difference was found in the long term efficiency of two  different ablation techniques (p = 0.211). Conclusion In our retrospective study we found no significant difference in the short and long term efficiency of two different therapeutic approaches to perimitral atrial flutter.
