Objective: We sought to identifyrepaired tetralogy of Fallot (rTOF) patients at high-risk of death and malignant ventricular arrhythmia (VA). Background: To date there is no robust risk stratification scheme to predict outcomes in adults with rTOF. Methods: Consecutive patients were prospectively recruited for late gadolinium enhancement cardiovascular magnetic resonance (LGE CMR) to define right and left ventricular (RV,LV) fibrosisin addition to proven risk markers. Results: The primary end-point was all-cause mortality. Of the 550 patients, (median age 32 years, 56% male), 27 died (mean follow-up 6.4 (±5.8); total 3512 years). Mortality was independently predicted by RVLGE extent, presence of LVLGE, RV ejection fraction (EF) ≤47%, LVEF ≤55%, B-type natriuretic peptide (BNP) ≥127ng/L, peak exercise oxygen uptake (V02) ≤17ml/kg/min, prior sustained atrial arrhythmia and age ≥50 years. The weighted scores for each of the above independent predictors differentiated a high-risk sub-group patients with a 4.4%, annual risk of mortality (AUC 0.87,P<0.001). The secondary end-point (VA), a composite of life-threatening sustained ventricular tachycardia/resuscitated ventricular fibrillation/sudden cardiac death occurred in 29. Weighted scores that included several predictors of mortality and RV outflow tractakinetic length ≥55mm and RVsystolic pressure ≥47mm Hg identified high-risk patients with a 3.7%, annual risk ofVA (AUC 0.79,P<0.001) RVLGE was heavily weighted in both risk scores due to its strong relative prognostic value. Conclusion: We present ascore integrating multiple appropriately weighted risk factors to identify the sub-group of rTOF patients that are at highannual risk of death who may benefit from targeted therapy.

BackgroundIn-hospital mortality is a rare, yet feared complication following cardiac surgery in adult congenital heart disease (ACHD). A risk score, developed and validated in ACHD, can be helpful to optimize risk assessment.ObjectivesTo assess the performance of EuroSCORE II components and procedure-related Adult Congenital Heart Surgery (ACHS) score, identify additional risk factors, and develop a novel risk score for predicting in-hospital mortality after ACHD surgery.MethodsWe assessed perioperative survival in patients >16 years undergoing congenital heart surgery in a large tertiary center between 2003 and 2019. A risk variable derived PErioperative ACHd (PEACH) score was calculated for each patient. Internal and external validation of the model was undertaken, including testing in a validation cohort of patients operated in a second European ACHD center. ResultsThe development cohort comprised 1782 procedures performed during the study period. Re-sternotomy was undertaken in 897(50.3%). There were 31(1.7%) in-hospital deaths. The PErioperative ACHd (PEACH) score showed excellent discrimination ability (AUC 0.88, 95%CI:0.83-0.94), and performed better than the ACHS score in our population (ACHS AUC 0.69, 95%CI:0.6-0.78, p=0.0003). A simple 3-tiered risk stratification was formed: PEACH score 0 (in-hospital mortality 0.2%), 1-2 (3.6%), ≥3 (17.2%). In a validation cohort of 975 procedures, the PEACH score retained its discriminative ability (AUC 0.75, 95%CI:0.72-0.77) and was well calibrated (Hosmer Lemishow 2 goodness-of-fit p=0.55). There was agreement in expected and observed perioperative mortality between cohorts.ConclusionsThe PEACH score is a simple, novel peri-operative risk score developed and validated specifically for ACHD patients undergoing cardiac surgery.

Surkova E, Segura T, Dimopoulos K, Bispo D, Flick C, West C, Babu-Narayan SV, Senior R, Gatzoulis MA, Li Wet al., 2021, Systolic dysfunction of the subpulmonary left ventricle is associated with the severity of heart failure in patients with a systemic right ventricle, International Journal of Cardiology, Vol: 324, Pages: 66-71, ISSN: 0167-5273

BACKGROUND: The study aimed to assess the relation between echocardiographic parameters of subpulmonary left ventricular (LV) size and function, and the severity of heart failure in patients with a systemic right ventricle (SRV). METHODS AND RESULTS: A total of 157 patients (89 post Mustard/Senning operations, 68 with congenitally corrected transposition of great arteries [ccTGA]) were included. The size and function of the SRV and subpulmonary LV were assessed on the most recent echocardiographic exam. Clinical data were collected from the electronic records. The majority (133, 84.7%) were in NYHA functional class 1-2. Median BNP concentration was 79.5[38.3-173.3] ng/l, and 100 (63.7%) patients were receiving heart failure therapy. Both LV and SRV fractional area change (FAC) differed significantly between patients with NYHA class 1-2 vs 3-4 (48[41.5-52.8]% vs 34[28.6-38.6]%, p < 0.0001 and 29.5[23-35]% vs 22[20-27]%, p < 0.0001, respectively), but LV FAC had a higher discriminative power for functional class >2 than SRV FAC (AUC 0.90, p < 0.0001 vs 0.79; p < 0.0001, respectively). A LV FAC cut-off value <39.2% had the highest accuracy in identifying patients with NYHA class 3-4 (sensitivity 83% and specificity 88%). In multivariable logistic regression analysis, LV FAC and SRV FAC independently associated to NYHA class 3-4 (OR 0.80 [95%CI 0.72-0.88], p < 0.0001 and OR 0.85 [95%CI 0.76-0.96], p = 0.007, respectively). CONCLUSIONS: Subpulmonary LV systolic dysfunction is associated with NYHA functional class 3-4 in patients with ccTGA or after Mustard or Senning operation. Careful evaluation of the subpulmonary LV should be a part of the routine assessment of patients with a SRV.

Background - Adults with repaired tetralogy of Fallot (rTOF) die prematurely from ventricular tachycardia (VT) and sudden cardiac death. Inducible VT predicts mortality. Ventricular scar, the key substrate for VT, can be non-invasively defined with late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) but whether this relates to inducible VT is unknown.Methods - Sixty-nine consecutive rTOF patients (43 male, mean 40{plus minus}15 years) clinically scheduled for invasive programmed VT-stimulation were prospectively recruited for prior 3D LGE CMR. Ventricular LGE was segmented and merged with reconstructed cardiac chambers and LGE volume measured.Results - VT was induced in 22(31%) patients. Univariable predictors of inducible VT included increased RV LGE (OR 1.15;p=0.001 per cm3), increased non-apical vent LV LGE (OR 1.09;p=0.008 per cm3), older age (OR 1.6;p=0.01 per decile), QRS duration ≥180ms (OR 3.5;p=0.02), history of non-sustained VT (OR 3.5; p=0.02) and previous clinical sustained VT (OR 12.8;p=0.003); only prior sustained VT (OR 8.02;p=0.02) remained independent in bivariable analyses after controlling for RV LGE volume (OR 1.14;p=0.003). An RV LGE volume of 25cm3 had 72% sensitivity and 81% specificity for predicting inducible VT (AUC 0.81;p<0.001). At the extreme cutoffs for 'ruling-out' and 'ruling-in' inducible VT, RV LGE >10cm3 was 100% sensitive and >36cm3 was 100% specific for predicting inducible VT.Conclusions - 3D LGE CMR-defined scar burden is independently associated with inducible VT and may help refine patient selection for programmed VT-stimulation when applied to an at least intermediate clinical risk cohort.

IntroductionArrhythmia contributes significantly to morbidity and mortality of patients with congenital heart disease (CHD) or cardiomyopathy (CMP). It also has the potential to worsen symptoms and is particularly detrimental to patients with advanced heart failure awaiting cardiac transplantation. We report our experience using catheter ablation to treat recurrent arrhythmia in patients with CHD or CMP considered for transplantation.MethodsFive consecutive patients (3 female, mean age 47.8 ± 12.8 years) with complex CHD or CMP (tricuspid atresia, mitral atresia, double inlet left ventricle, arrhythmogenic right ventricular cardiomyopathy, left ventricular non-compaction) presented with either atrial (n = 3) or ventricular (n = 2) arrhythmias. All ablations were guided by three-dimensional (3D) electro-anatomical mapping, plus remote magnetic navigation in 3 patients.ResultsPatients underwent a median of 2 ablation procedures for a total number of 26 tachycardias. None of the 5 patients experienced further arrhythmia at a median of 939 days (range 4–1375) from their last ablation. During a median follow up of 31 months (range 1–70), three patients underwent successful transplantation at 1375, 1062 and 321 days following their last ablation. One patient with a Fontan circulation died from hepatic cancer and one from end-stage heart failure despite urgent transplant listing.ConclusionsCatheter ablation is feasible in complex cardiac patients considered for heart transplantation and should be offered for rhythm management and patient optimization until a suitable donor is found.

Background: There are limited data regarding cardiac resynchronization therapy (CRT) in adult congenital heart disease (ACHD). We aimed to assess early and late outcomes of CRT amongst patients with ACHD.Methods: We retrospectively studied ACHD patients receiving CRT (2004-2017). Clinical and echocardiographic data were analyzed at baseline, early (1.8±0.8 years) and late (4.7±0.8 years) follow-up after CRT.Results: Fifty-four ACHD patients (median age 46 years, range 18-73 years, 74% male) had CRT (biventricular paced >90%) and were followed for 5.7±3.0 years. Compared to baseline, CRT was associated with significant improvement at early follow-up in NYHA functional class, QRS duration and cardiothoracic ratio (P<0.05 for all); improvement in NYHA class was sustained at late follow-up.Amongst patients with a systemic left ventricle (LV; n=39), there was significant increase in LV ejection fraction (LVEF) and reduction in LV end-systolic volume at early and late follow up (P<0.05 for both). For patients with a systemic right ventricle (RV; n=15), there was a significant early but not late reduction in systemic RV basal and longitudinal diameters.Eleven patients died and 2 had heart transplantation unrelated to systemic ventricular morphology. Thirty-five (65%) patients responded positively to CRT but only baseline QRS duration was predictive of a positive response.Conclusions: CRT results in sustained improvement in functional class, systemic LV size and function. Patients with a systemic LV and prolonged QRS duration, independent of QRS morphology, were most likely to respond to CRT.

Aims: To investigate the utility of novel deep learning (DL) algorithms in recognizing transposition of the great arteries (TGA) after atrial switch procedure or congenitally corrected TGA (ccTGA) based on routine transthoracic echocardiograms. In addition, the ability of DL algorithms for delineation and segmentation of the systemic ventricle was evaluated. Methods and results: In total, 132 patients (92 TGA and atrial switch and 40 with ccTGA; 60% male, age 38.3 ± 12.1 years) and 67 normal controls (57% male, age 48.5 ± 17.9 years) with routine transthoracic examinations were included. Convolutional neural networks were trained to classify patients by underlying diagnosis and a U-Net design was used to automatically segment the systemic ventricle. Convolutional networks were build based on over 100 000 frames of an apical four-chamber or parasternal short-axis view to detect underlying diagnoses. The DL algorithm had an overall accuracy of 98.0% in detecting the correct diagnosis. The U-Net architecture model correctly identified the systemic ventricle in all individuals and achieved a high performance in segmenting the systemic right or left ventricle (Dice metric between 0.79 and 0.88 depending on diagnosis) when compared with human experts. Conclusion: Our study demonstrates the potential of machine learning algorithms, trained on routine echocardiographic datasets to detect underlying diagnosis in complex congenital heart disease. Automated delineation of the ventricular area was also feasible. These methods may in future allow for the longitudinal, objective, and automated assessment of ventricular function.
