OBJECTIVE
Moderate to severe mitral regurgitation (MR) and tricuspid regurgitation (TR) are present in approximately 20-60% of patients undergoing transcatheter aortic valve implantation (TAVI). This study aims to evaluate the impact of TAVI on MR and TR, pulmonary hypertension, and reverse cardiac remodeling in these patients. Methods: Out of 240 patients who underwent TAVI, 79 who met the inclusion and exclusion criteria were analyzed.
RESULTS
In our study, 46.8% (n = 37) of the patients were male. Nineteen (24.1%) patients died within two years. Before TAVI, 34 (43%) patients had moderate-to-severe MR, which decreased to 18 (22.7%) after the procedure (P < 0.05). Similarly, the number of patients with moderate-to-severe TR decreased from 26 (32.9%) before TAVI to 12 (15%) after the procedure (P < 0.05). Of the patients, 50.6% (n = 40) did not require hospitalization after the procedure, while 25 were hospitalized once, 12 twice, and 2 three times. The mean systolic pulmonary artery pressure (sPAP) values of the patients decreased from 44.30 ± 14.42 mmHg before the procedure to 39.09 ± 11.77 mmHg after the procedure (Z=-3.506, P < 0.001). No correlation was found between changes in MR and TR grades after TAVI and mortality or hospitalization during follow-up. Furthermore, there was no statistically significant difference in tricuspid annular plane systolic excursion (TAPSE), free wall annular S' velocity, left atrial volume (LAV), or LAV index (LAVI) before and after TAVI. Conclusion: There was a significant decrease in moderate-to-severe MR and TR after TAVI; however, this did not impact hospitalization or mortality rates. Additionally, no significant differences were observed in right ventricular systolic function or in LAV and LAVI before and after TAVI.

BACKGROUND
Many patients with repaired tetralogy of Fallot require pulmonary valve replacement (PVR) due to significant pulmonary regurgitation (PR). Transcatheter PVR (TPVR) is an equally effective and less invasive alternative to surgical PVR but many native right ventricular outflow tracts (RVOTs) are too large for TPVR at time of referral. Understanding the rate of growth of the RVOT may help optimize timing of referral. This study aims to examine the longitudinal growth of the native RVOT over time in repaired tetralogy of Fallot (TOF).
METHODS
A retrospective review of serial cardiac MRI cardiovascular magnetic resonance (CMR) data from 121 patients with repaired TOF and a native RVOT (median age at first CMR 14.7 years, average interval between the first and last CMR of 8.1 years) was performed to measure serial changes in RVOT diameter, cross-sectional area, perimeter-derived diameter, and length.
RESULTS
All parameters of RVOT size continued to grow with increasing age but growth was more rapid in the decade after TOF repair (for minimum systolic diameter, mean increase of 5.7 mm per 10 years up to year 12, subsequently 2.3 mm per 10 years). The RVOT was larger with a transannular patch and in patients without pulmonary stenosis (p < 0.001 for both), but this was not associated with rate of growth. More rapid RVOT enlargement was noted in patients with larger right ventricular end-diastolic volume (RVEDV), higher PR fraction, and greater rates of increases in RVEDV and PR (p < 0.001 for all) CONCLUSIONS: in patients with repaired TOF, using serial CMR data, we found that RVOT size increased progressively at all ages, but the rate was more rapid in the first decade after repair. More rapid RVOT enlargement was noted in patients with a larger RV, more PR, and greater rates of increases in RV size and PR severity. These results may be important in considering timing of referral for transcatheter pulmonary valves, in planning transcatheter and surgical valve replacement, and in designing future valves for the native RVOT.

Association of endomyocardial fibrosis and minor myocarditis sequelae with intracardiac thrombus and Ebstein like valvulopathy in a patient with Behçet disease: a case report.
BACKGROUND
Cardiac complications occur in 1-6% of cases of Behçet disease (BD) with intracardiac thrombus being the most frequent complication. Endomyocardial fibrosis, less common and occasionally associated with intracardiac thrombus, is reported in <20 case reports of BD, among which, three cases are described to mimic Ebstein disease based on echocardiography. We present the first case in the literature of a 34-year-old man with BD diagnosed with multiple cardiovascular complications, highlighting the challenging diagnosis and treatment of this pathology, especially regarding anticoagulation therapy.
CASE SUMMARY
A 34-year-old man, diagnosed with BD, presented to the Emergency Room with haemoptysis. Computed tomography study of the thorax diagnosed pulmonary arterial aneurysm with multiple arterial thrombi, associated with multiple intracardiac thrombi in the right ventricle and atrium. The echocardiography confirmed the presence of voluminous thrombi in the right ventricle and atrium and showed hypertrabeculation of the right ventricle and a high insertion of the posterior leaflet of the tricuspid valve inducing a moderate tricuspid insufficiency compatible with an Ebstein disease. The cardiac MRI later revealed right ventricular fibrosis consistent with endomyocardial fibrosis and sequelae of myocarditis, also described as BD rare cardiac manifestations. The patient had a favourable outcome under anticoagulant treatment and immunosuppressive drugs.
DISCUSSION
The association of multiple cardiovascular complications can occur in a single patient with BD. The endomyocardial fibrosis in the right heart chambers acting as a substrate for thrombus formation and subsequent pulmonary embolism; fibrosis extending to the tricuspid valve inducing an Ebstein-like morphology.

BACKGROUND
Patients with repaired Tetralogy of Fallot (rTOF) often develop pulmonary regurgitation (PR) and right ventricle (RV) dysfunction, experiencing increased mortality and morbidity rates in adulthood. Pulmonary valve replacement (PVR) timing to address PR is controversial. Cardiac Magnetic Resonance (CMR) is the gold standard for morpho-functional evaluation of complex cardiopathies. This study aims to identify CMR parameters predictive of adverse outcomes to help defining the best therapeutic management of rTOF patients.
METHODS
130 rTOF patients who underwent CMR (2006-2019) were enrolled in this retrospective single-center study. CMR, clinical, ECG and exercise data were analyzed. Univariate and multivariate analyses identified clinical and CMR parameters predictive of adverse outcomes both individually (e.g., death, arrhythmias, heart failure (HF), pharmacological therapy, QRS ≥ 160ms) and as composite outcome.
RESULTS
Univariate analysis confirmed RV volumes and RV ejection fraction corrected for PR as adverse outcome predictors and identified interesting correlations: pulmonary artery bifurcation geometry and abnormal interventricular septum (IVS) motion with arrhythmias (p < .001; p = .037), HF (p = .049; p = .005), composite outcome (p = .039; p = .009); right atrium (RA) dimensions with the composite outcome and the outcomes individually (p < .001). The best predictive models by multivariate analysis included sex (male), RV and RA dilation for QRS ≥ 160ms, time form repair to CMR, age at TOF repair and IVS fibrosis for pharmacological therapy.
CONCLUSIONS
Besides RV volumes, new adverse prognostic factors could guide rTOF therapeutic management: pulmonary arteries morphology, abnormal IVS motion, RV dysfunction, RA dilation. Perspective multicentric evaluation is needed to specify their effective role.

BACKGROUND
Despite numerous advantages of the Ross procedure, it presents a risk of late autograft and right ventricular outflow tract conduit failure. This study aimed to analyze the outcomes of autograft dysfunction reoperations using autograft-sparing and root replacement techniques.
METHODS
Between 2015 and 2023, 49 patients underwent redo root surgery in our institution. Autograft valve-sparing procedures (VSP) were performed in 20 cases and the Bentall procedure (BP) in 29 patients. The short and long-term clinical outcomes along with echocardiographic results of VSP and BP were investigated.
RESULTS
Overall early mortality rate was 2.0% with no significant difference between the groups. Severe autograft valve insufficiency at the time of redo (OR 4.07, = 0.03) and patient age (OR 1.07, = 0.04) were associated with a valve replacement procedure instead of VSP. The median follow-up duration was 34 months. No late deaths occurred in either group. Freedom from VSP failure and aortic prosthesis dysfunction were 93.8% and 94.1% in the VSP and BP groups, respectively. No reoperations were necessary in either group.
CONCLUSION
Redo aortic root surgery can be safely performed in patients with autograft failure. Both root replacement and autograft valve-sparing procedures demonstrated acceptable results at mid-term follow-up. Early redo surgery pre-empting severe aortic insufficiency increases the likelihood of preservation of the dilated autograft valve.

Review
In the latest ESC/EACTS Guidelines for the Management of Valvular Heart Disease, right ventricular dilatation and dysfunction, severe pulmonary hypertension and tricuspid annulus dilatation were reported to be the most important parameters to consider in patient selection for tricuspid valve interventions. Indeed, comprehensive right ventricular assessment is crucial in patients with severe tricuspid regurgitation who may benefit from transcatheter or surgical procedures. However, the only guideline parameter considered for intervention has been tricuspid annular dilatation in the presence of at least mild to moderate tricuspid regurgitation, with no other right ventricular markers used in the decision-making process for invasive treatment. Notably, challenges in the assessment of right ventricular function may limit establishing thresholds for defining right ventricular dysfunction. The aim of this review is to summarize current evidence on the prognostic significance of right ventricular function in patients with tricuspid regurgitation undergoing percutaneous or surgical interventions.

Review
There is conclusive evidence for relief of pulmonary valve obstruction immediately after balloon pulmonary valvuloplasty (BPV) and at follow-up. Development of infundibular obstruction is seen in more severe PS cases and in older subjects. Reappearance of PS was observed in approximately 10 % of patients following BPV. The reasons for recurrence were found to be balloon/annulus ratio less than 1.2 and immediate post-BPV pulmonary valve peak gradients greater than 30 mmHg. Recurrent stenosis is successfully addressed by repeating BPV with lager balloons than used initially. Long-term results revealed continue relief of obstruction, but with development of pulmonary insufficiency, some patients requiring replacement of the pulmonary valve. It was concluded that BPV is the treatment of choice in the management valvar PS and that balloon/annuls ratio used for BPV should be lowered to 1.2 to 1.25. It was also suggested that strategies should be developed to prevent/reduce pulmonary insufficiency at long-term follow-up.

BACKGROUND
Robust data on changes in pulmonary valve replacement (PVR) procedural volume and predictors of bioprosthetic pulmonary valve (BPV) durability in patients with tetralogy of Fallot (TOF) are scarce.
OBJECTIVES
This study sought to assess temporal trends in PVR procedural volume and BPV durability in a nationwide, retrospective TOF cohort.
METHODS
Data were obtained from patient records. Robust linear regression was used to assess temporal trends in PVR procedural volume. Piecewise exponential additive mixed models were used to estimate BPV durability, defined as the time from implantation to redo PVR with death as a competing risk, and to assess risk factors for reduced durability.
RESULTS
In total, 546 PVR were performed in 384 patients from 1976 to 2021. The annual number of PVR increased from 0.4 to 6.0 per million population (P < 0.001). In the last decade, the transcatheter PVR volume increased by 20% annually (P < 0.001), whereas the surgical PVR volume did not change significantly. The median BPV durability was 17 years (Q1: 10-Q3: 10 years-not applicable). There was no significant difference in the durability of different BPV after adjustment for confounders. Age at PVR (HR: 0.78 per 10 years from <1 year; 95% CI: 0.63-0.96; P = 0.02) and true inner valve diameter (9-17 mm vs 18-22 mm HR: 0.40; 95% CI: 0.22-0.73; P = 0.003 and 18-22 mm vs 23-30 mm HR: 0.59; 95% CI: 0.25-1.39; P = 0.23) were associated with reduced BPV durability in multivariate models.
CONCLUSIONS
The PVR procedural volume has increased over time, with a greater increment in transcatheter than surgical PVR during the last decade. Younger patient age at PVR and a smaller true inner valve diameter predicted reduced BPV durability.

BACKGROUND
Dilated cardiomyopathy (DCM) is a rare disease that causes heart failure due to malfunction of the heart muscle characterized by left ventricular dilation and poor systolic function. Genetic screening leads to advantages in early diagnosis and prognostic assessment of patients with suspected inherited cardiomyopathies. Here, we report a case of neonatal dilated cardiomyopathy due to a mutation of the gene, which has not been published in neonatal dilated cardiomyopathy before.
CASE PRESENTATION
The patient was a 22-day-old newborn boy with poor ability to respond to stimuli, presenting with shortness of breath over 11 days. He presented with irregular fever, tachypnea, difficulty in ventilator withdrawal, and mild edema of both lower limbs, and III/6SM could be heard in the precardiac area. He presented repeated weaning difficulties during hospitalization with intractable low EF heart insufficiency. Doppler echocardiography showed refractory low ejection fraction, cardiac enlargement, cardiac insufficiency, mild pulmonary hypertension, and mitral and tricuspid insufficiency with mild valve regurgitation. Whole-exome sequencing showed a mutation in the gene, c. 544G>A (p.Glu182Lys). Thus, he was diagnosed with neonatal DCM. There was no mutation in the parents, the child died 2 weeks after discharge.
CONCLUSIONS
mutation is a novel likely pathogenic mechanism of neonatal dilated cardiomyopathy. Therefore, systematic use of diagnostic tools, advanced risk models, and a deeper understanding of the mechanism are required to reduce morbidity and mortality in this disease.

INTRODUCTION
Acute mitral regurgitation (MR) due to papillary muscle rupture (PMR) is a rare but lethal mechanical complication of acute myocardial infarction (MI). The treatment of patients with post-MI PMR, especially those with cardiogenic shock, presents great challenges due to the high surgical risk.
PATIENT CONCERNS
We report an 80-year-old woman with a history of hypertension and diabetes mellitus, presented with chest pain. Despite an early percutaneous coronary intervention and transfer to the intensive care unit, her general condition and hemodynamic parameters continued to deteriorate rapidly.
DIAGNOSIS
Evidenced by electrocardiogram, echocardiogram and coronary angiography, the patient was diagnosed with acute lateral and posterior ST-segment elevation MI, cardiogenic shock, PMR, severe MR, and pulmonary edema.
INTERVENTIONS
The patient received percutaneous mitral valve repair with MitraClip (Abbott Vascular, Santa Clara, CA, USA) supported by extracorporeal membranous oxygenation and intra-aortic balloon pump.
OUTCOMES
The patient was discharged with relief of heart failure symptoms, reduced MR, and recovery of cardiac function, remaining in a stable condition in New York Heart Association class I after 15-month outpatient follow up.
CONCLUSION
Transcatheter edge-to-edge repair with MitraClip can serve as a viable alternative to surgery in reducing MR in post-MI PMR patients at high surgical risk.
