The aim of this study was to analyze results of stenting atrioseptostomy in patients with pulmonary arterial hypertension and a different level of risk for one-year mortality that is not well described. Patients that underwent atrioseptostomy with stenting were retrospectively divided in two groups: “intermediate” (n = 55) or “high” risk (n = 13), according to the 2015 ESC/ESR guideline. Results of atrioseptostomy were assessed during hospital period and at follow-up. Patients from “intermediate” risk group demonstrated lower mortality rate (10/55, vs. 6/13) during the course of the study period, as well as higher freedom from lung transplantation or Potts shunt. At discharge, patients of both groups presented improvement in functional class and mobility. Patients from “intermediate” risk group showed longer 6-min walking distance, and lower levels of brain natriuretic peptide. At the latest follow-up, stable position and full patency of stents with right-to-left or bidirectional shunt at atrial level and absence of syncope was confirmed in patients of both groups. Patients from the “intermediate” risk group demonstrated higher functional class, better performance of walking test, and lower levels of brain natriuretic peptide. Stenting atrioseptostomy reliably secured interatrial communication and improved clinical condition in patients with idiopathic pulmonary arterial hypertension. Mid-term results were better in “intermediate” risk group.

We present an original surgical approach--posterolateral thoracotomy--for hybrid stage I procedure. This is a review of prospectively collected data on patients treated for hypoplastic left heart syndrome (HLHS) using a hybrid approach (n=33) between December 2007 and March 2010. The hybrid approach includes pulmonary artery bands, a ductal stent through posterolateral thoracotomy access. Overall survival was 88.5%. Our original surgical approach in hybrid stage I on patients treated for HLHS can yield acceptable intermediate results that are comparable with a traditional Norwood strategy. Potential advantages of the lateral thoracotomy in the hybrid approach include the avoidance of median sternotomy, minimal postoperative pericardial adhesions, better access to patent ductus arteriosus (PDA) stenting, the possibility of visual and manual control of the stent position, and short operative time.

Transcatheter valve replacement is now widely used to treat high-risk patients. This approach is also expanding to the tricuspid valve, mostly for "valve-invalve" and "valve-in-ring" implantations. Rapid pacing during transcatheter valve implantation is used to reduce cardiac output and minimize the risk of valve dislodgement. Rapid pacing is usually done using the patient's permanent pacemaker or a temporary pacing electrode that is usually introduced retrogradely into the left ventricle or coronary sinus. Here, we describe the use of the tricuspid valve-in-valve implantation super-stiff guidewire for rapid pacing during implantation of the valve. This approach may obviate the need for ancillary steps that may increase procedure time, X-ray exposure, and risk of complications.
