“…The echo nding consistent with severely restrictive RV physiology is the presence of antegrade ow into the PAs during diastole [12][13][14]. Due to the inability of the RV to ll during diastole, the RV acts as a passive channel, which can be easily detected by the presence of antegrade ow into the PAs during late diastole at echo.…”

Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect, includes a broad spectrum of RVOTO and multiple variants with surgical interventions and postoperative management tailored to each patient. In our study, we compared the morbidity and mortality rates of our two different surgical approaches according to the surgical criteria that have changed in the last 26 years. Material and Method:Total correction surgery was performed on 967 patients with tetralogy of Fallot by the same surgical team in our clinic. The patients were divided into 2 groups, 340 in Group 1 and 627 in Group 2, according to preoperative criteria. Demographic data of the patients, preoperative evaluation methods, additional pathologies of the patients in the preoperative period, palliative operations performed before total correction and early postoperative complications were evaluated. Results: A significant difference was observed in the mortality and morbidity outcomes of the 2 groups compared. Since the number of patients < 1 year was higher in Group 2 compared to Group 1, less palliative surgery was performed before total correction. Our patients in Group 2 had a lower incidence of postoperative complications, low cardiac output, and arrhythmia. Conclusion: Correction of the pathology at an early age in symptomatic patients with a diagnosis of Tetralogy of Fallot positively affects the prognosis of the patient. In addition, early diagnosis and treatment in all patients with or without symptoms have a significant impact on the prognosis of complications that may occur in the postoperative period. We believe that one of the biggest factors in surgical success is an experienced surgical team that has worked together for many years.

“…How to define ESP from the pressure curve remains a challenge when using single-beat methods to estimate Ees. This problem applies especially to the RV due to the more triangular shape of the RV PV loop (Redington 2014). In this study, we used RV SP as a surrogate of RV ESP.…”

ObjectivePressure-volume loop analysis, traditionally performed by invasive pressure and volume measurements, is the optimal method for assessing ventricular function, while cardiac magnetic resonance (CMR) imaging is the gold standard for ventricular volume estimation. The aim of this study was to investigate the agreement between the assessment of end-systolic elastance (Ees) assessed with combined CMR and simultaneous pressure catheter measurements compared with admittance catheters in a porcine model. ApproachSeven healthy pigs underwent admittance-based pressure-volume loop evaluation followed by a second assessment with CMR during simultaneous pressure measurements. Main resultsAdmittance overestimated end-diastolic volume for both the left ventricle (LV) and the right ventricle (RV) compared with CMR. Further, there was an underestimation of RV end-systolic volume with admittance. For the RV, however, Ees was systematically higher when assessed with CMR plus simultaneous pressure measurements compared with admittance whereas there was no systematic difference in Ees but large differences between admittance and CMR-based methods for the LV.Significance LV and RV Ees can be obtained from both admittance and CMR based techniques. There were discrepancies in volume estimates between admittance and CMR based methods, especially for the RV. RV Ees was higher when estimated by CMR with simultaneous pressure measurements compared with admittance.
