RESUMEN
Atrio-esophageal fistula (AEF) is a rare (0.02-0.1%) complication of radiofrequency ablation for atrial fibrillation and is associated with high mortality. It typically presents between 2 and 6 weeks after catheter ablation. AEF was reported to be the second complication as cause of death after radiofrequency ablation with a mortality rate of 71%. Common clinical features of AEF include dysphagia, nausea, heartburn, hematemesis or melena, high fever, sepsis, pericardial or pleural effusions, mediastinitis, seizures, and stroke. Once the diagnosis of AEF is made, early surgical repair is mandatory. Herein, we report a case of a AEF treated surgically without extracorporeal circulation.

Left Ventricular Assist Devices (LVADs) represent an important therapeutic option in the management of advanced heart failure. We report a case of 74 years-old male with a Jarvik 2000® (Jarvik Heart, New York, USA) LVAD who presented with an infection of the LVAD driveline due to methicillin-resistant Staphylococcus aureus (MRSA) that was treated with dalbavancin as chronic antimicrobial suppression therapy without adverse events and maintaining a good quality of life for more than 37 weeks. Dalbavancin could represent a valid option for the treatment of LVAD infections because of its efficacy, pharmacokinetic/pharmacodynamic proprieties, safety and tolerability.

BACKGROUND: Right ventricular failure (RVF) is a severe event that increases perioperative mortality after left ventricle assist device (LVAD) implantation. Right ventricular (RV) function is particularly affected by the LVAD speed by altering RV preload and afterload as well as the position of the interventricular septum. However, there are no studies focusing on the relationship between pump speed optimization and risk factors for the development of late RVF. METHODS: Between 2015 and 2019, 50 patients received LVAD implantation at San Camillo Hospital in Rome. Of these, 38 who underwent pump speed optimization were included. Post-optimization hemodynamic data were collected. We assessed a new Hemodynamic Index (HI), calculated as follows: HI = MAP × PCWP CVP × RPM set RPM max , to determine the risk of late RVF, which was defined as the requirement for rehospitalization and inotropic support. RESULTS: Ten patients had late RVF after LVAD implantation. Five patients required diuretic therapy and speed optimization. Three patients required inotropic support with adrenaline 0.05 µg/kg/min. Two patients needed prolonged continuous venovenous hemofiltration and high dose inotropic support. Multivariate analysis revealed that a low HI (odds ratio 11.5, 95% confidence interval, 1.85-65.5, p [.003]) was an independent risk factor for late RVF after LVAD implantation. CONCLUSION: We demonstrated a low HI being a significant risk factor for the development of RVF after LVAD implantation. We suggest implementing HI as a decision support tool for goal-direct optimization of the device aiming to reduce the burden of late-onset RVF during the follow-up.

Coronary artery bypass grafting has long been the standard of care for patients with left main coronary artery (LMCA) disease. Lately, percutaneous coronary intervention (PCI) has become a suitable alternative for these patients, but the procedure may be challenging. We describe 2 cases of LMCA PCI failure requiring surgical intervention. (Level of Difficulty: Advanced.).
