Abstract
BACKGROUND Pulmonary hypertension (PH) and secondary mitral regurgitation (MR) are associated with adverse outcomes after mitral transcatheter edge-to-edge repair. We aim to study the prognostic value of invasively measured right ventricular afterload in patients undergoing mitral transcatheter edge-to-edge repair. METHODS AND RESULTS We identified patients who underwent right heart catheterization ≤1 month before transcatheter edge-to-edge repair. The end points were all-cause mortality and a composite of mortality and heart failure hospitalization at 2 years. Using the receiver operating characteristic curve-derived threshold of 0.6 for pulmonary effective arterial elastance ([Ea], pulmonary artery systolic pressure/stroke volume), patients were stratified into 3 profiles based on PH severity (low elastance [HE]: Ea <0.6/mean pulmonary artery pressure (mPAP)) <35; High Elastance with No/Mild PH (HE-): Ea ≥0.6/mPAP <35; and HE with Moderate/Severe PH (HE+): Ea ≥0.6/mPAP ≥35) and MR pathogenesis (Primary MR [PMR])/low elastance, PMR/HE, and secondary MR). The association between this classification and clinical outcomes was examined using Cox regression. Among 114 patients included, 50.9% had PMR. Mean±SD age was 74.7±10.6 years. Patients with Ea ≥0.6 were more likely to have diabetes, atrial fibrillation, New York Heart Association III/IV status, and secondary MR (all P<0.05). Overall, 2-year cumulative survival was 71.1% and was lower in patients with secondary MR and mPAP ≥35. Compared with patients with low elastance, cumulative 2-year event-free survival was significantly lower in HE- and HE+ patients (85.5% versus 50.4% versus 41.0%, respectively, P=0.001). Also, cumulative 2-year event-free survival was significantly higher in patients with PMR/low elastance when compared with PMR/HE and patients with secondary mitral regurgitation (85.5% versus 55.5% versus 46.1%, respectively, P=0.005). CONCLUSIONS Assessment of the preprocedural cardiopulmonary profile based on mPAP, MR pathogenesis, and Ea guides patient selection by identifying hemodynamic features that indicate likely benefit from mitral-transcatheter edge-to-edge repair in PH or lack thereof.

Abstract
BACKGROUND Prior studies investigating the impact of residual mitral regurgitation (MR), tricuspid regurgitation (TR), and elevated predischarge transmitral mean pressure gradient (TMPG) on outcomes after mitral transcatheter edge-to-edge repair (TEER) have assessed each parameter in isolation. We sought to examine the prognostic value of combining predischarge MR, TR, and TMPG to study long-term outcomes after TEER. METHODS AND RESULTS We reviewed the records of 291 patients who underwent successful mitral TEER at our institution between March 2014 and June 2022. Using well-established outcomes-related cutoffs for predischarge MR (≥moderate), TR (≥moderate), and TMPG (≥5 mm Hg), 3 echo profiles were developed based on the number of risk factors present (optimal: 0 risk factors, mixed: 1 risk factor, poor: ≥2 risk factors). Discrimination of the profiles for predicting the primary composite end point of all-cause mortality and heart failure hospitalization at 2 years was examined using Cox regression. Overall, mean age was 76.7±10.6 years, 43.3% were women, and 53% had primary MR. Two-year event-free survival was 61%. Predischarge TR≥moderate, MR≥moderate, and TMPG≥5 mm Hg were risk factors associated with the primary end point. Compared with the optimal profile, there was an incremental risk in 2-year event-rate with each worsening profile (optimal as reference; mixed profile: hazard ratio (HR), 2.87 [95% CI, 1.71-5.17], P<0.001; poor profile: HR, 3.76 [95% CI, 1.84-6.53], P<0.001). Echocardiographic profile was statistically associated with the 2-year mortality end point (optimal as reference; mixed profile: HR, 3.55 [95% CI, 1.81-5.96], P<0.001; poor profile: HR, 3.39 [95% CI, 2.56-7.33], P=0.02). CONCLUSIONS The echocardiographic profile integrating predischarge TR, MR, and TMPG presents a novel prognostic stratification tool for patients undergoing mitral TEER.

Abstract
Data on the use of intracardiac echocardiography (ICE) guidance in mitral transcatheter edge-to-edge repair (mTEER) procedure is limited to case reports and small case series. Our study aims to assess the feasibility, safety, utilization patterns, and clinical outcomes of mTEER procedure with ICE guidance using a nationally representative real-world cohort of patients. This study used the National Inpatient Sample database from quarter 4 of 2015 to 2020. We used a propensity-matched analysis and adjusted odds ratios for in-hospital outcomes/complications. A P value of < 0.05 was considered significant. A total of 38,770 weighted cases of mTEER were identified. Of the included patients 665 patients underwent ICE-guided mTEER while 38,105 had TEE-guided mTEER. There were no differences in the in-hospital mortality between both groups (2.5% vs 3.0%, P = 0.58). Adjusted odds of in-hospital mortality (aOR 0.83, 95%CI [0.42-1.64]) were not significantly different. There were no differences in periprocedural complications including cardiac (aOR 0.85, 95%CI [0.54-1.35]), bleeding (aOR 1.45, 95%CI [0.93-2.33]), respiratory (aOR 0.88, 95%CI [0.61-1.25]), and renal (aOR 0.89, 95%CI [0.66-1.20]) complications between patients undergoing ICE-guided vs TEE-guided mTEER. There was no difference in GI complications between both groups (aOR 1.11, 95%CI [0.46-2.70]). The adjusted length of stay was less among ICE-guided mTEER (median: 1 vs 2, P < 0.01) with lower inflation-adjusted costs of hospitalization ($35,513 vs $47,067, P < 0.01). ICE-guided mTEER is safe when compared with TEE guided mTEER with no significant differences in in-hospital mortality, cardiac, bleeding, respiratory, and renal complications.

Abstract
The aim of this study is to analyze the relationship between QRS duration after pulmonary valve replacement (PVR) and ventricular arrhythmias (VA) in patients with repaired tetralogy of Fallot (ToF). ToF patients may face complications such as heart failure and VA after primary repair, often mitigated by PVR. Prior studies have shown a decrease in QRS duration and right ventricular (RV) size following PVR. It remains unclear whether a lack of QRS duration reduction identifies patients at risk of VA. We retrospectively identified adult patients with repaired ToF who underwent surgical or transcatheter PVR. EKG data (pre-PVR, 30 days to 1-year post-PVR, and closest to CMR) was collected. The primary endpoint was sustained ventricular tachycardia (VT), ICD shock for sustained VT, or inducible VT on EP study. 85 patients were included (median follow-up 3.6 years; median age 34 years; 51% females). The primary outcome was noted in 8 patients. Mean QRS duration decreased by 5 ms following PVR (p = 0.0001). Increased age at PVR, QRS ≥ 180 ms post-PVR, no reduction in QRS after PVR, and a history of VT were associated with higher risk of the primary endpoint. The change in QRS was linearly correlated with the change in RVEDVi (R = 0.66). Adults with repaired ToF experience a reduction in QRS duration post-PVR that correlates with the change of the RV size. Patients with QRS ≥ 180 ms post-PVR, no reduction in QRS, increased age at repair, and a history of VT are at risk for recurrent VT and warrant closer monitoring/ICD consideration.

Abstract
Background The clinical significance of mitral annular calcification (MAC) in patients undergoing mitral transcatheter edge-to-edge repair is not well understood. There is limited evidence regarding the feasibility, durability of repair, and the prognostic value of MAC in this population. We sought to examine the prognostic value of MAC, its severity, and its impact on procedural success and durability of mitral transcatheter edge-to-edge repair. Methods and Results We reviewed the records of 280 patients with moderate-severe or severe mitral regurgitation who underwent mitral transcatheter edge-to-edge repair with MitraClip from March 2014 to March 2022. The primary end point was cumulative survival at 1 year. Independent factors associated with the primary end point were identified using multivariable Cox regression. Among 280 patients included in the final analysis, 249 had none/mild MAC, and 31 had moderate/severe MAC. Median follow-up was 23.1 months (interquartile range: 11.1-40.4). Procedural success was comparable in the MAC and non-MAC groups (92.6% versus 91.4%, P=0.79) with similar rates of residual mitral regurgitation ≤2 at 1 year (86.7% versus 93.2%, P=0.55). Moderate/severe MAC was associated with less improvement in New York Heart Association III/IV at 30 days when compared with none/mild MAC (45.8% versus 14.3%, P=0.001). The moderate/severe MAC group had lower cumulative 1-year survival (56.8% versus 80.0%, hazard ratio [HR], 1.98 [95% CI, 1.27-3.10], P=0.002). Moderate/severe MAC and Society of Thoracic Surgeons predicted risk of mortality for mitral valve repair were independently associated with the primary end point (HR, 2.20 [1.10-4.41], P=0.02; and HR, 1.014 [1.006-1.078], P=0.02, respectively). Conclusions Mitral TEER is a safe and feasible intervention in selected patients with significant MAC and associated with similar mitral regurgitation reduction at 1 year compared with patients with none/mild MAC. Patients with moderate/severe MAC had a high 1-year mortality and less improvement in their symptoms after TEER.

Abstract
Patients who underwent transcatheter edge-to-edge repair (TEER) or transcatheter mitral valve replacement (TMVR) have a transeptal access created by an iatrogenic atrial septal defect (ASD) which leads to significant complications requiring closure. Given limited data, we used the National Inpatient Sample between 2015 and 2020 to evaluate the clinical outcomes of percutaneous closure of ASD (PC-ASD) in TEER/TMVR hospitalizations. A total of 44,065 eligible weighted hospitalizations with either TEER (n = 39,625, 89.9%) or TMVR (n = 4,440, 10.1%) with a higher rate of PC-ASD in the TMVR group (10.7% vs 2.0%, p <0.01). The TEER with PC-ASD group were more likely to experience acute heart failure and right ventricular failure and had longer hospital stays but there was no difference in in-hospital mortality compared with the no PC-ASD group. In the TMVR group, there was no difference in the odds of acute heart failure, right ventricular failure, cardiogenic shock, or acute hypoxic respiratory failure, but the odds of mechanical circulatory support, in-hospital mortality, and length of stay were significantly higher in patients with PC-ASD in the TMVR group. In conclusion, rates of percutaneous closure of ASD after TEER were lower than after TMVR and associated with worse in-hospital mortality in TMVR but not in TEER. Further prospective clinical trials are needed to identify patients who would benefit from the closure of iatrogenic ASD.

Abstract
Thirty four-year-old male with history of D-transposition of the great arteries (D-TGA) who underwent Mustard operation at 14 months of age presented in cardiogenic shock secondary to severe systemic right ventricular failure. Catheterization revealed significantly increased pulmonary pressures. Due to the patient's inotrope dependence and prohibitive pulmonary hypertension, he underwent implantation of a Heart Ware HVAD® for systemic RV support. Within 4 months of continuous flow ventricular assist device (VAD) implantation complete normalization of pulmonary vascular resistance (PVR) was achieved. He ultimately underwent orthotopic heart transplantation with favorable outcomes. This is the second report of complete normalization of PVR following VAD implantation into a systemic RV in <4 months. We conducted a thorough literature review to identify Mustard patients that received systemic RV VAD as a bridge to a successful heart transplantation. In this article, we summarize the outcomes and focus on pulmonary hypertension reversibility following VAD implant.

Abstract
The role of lipocalin 2 (LCN2) in pulmonary hypertension (PH) in pediatric patients with congenital heart disease (CHD) remains unclear. We sought to investigate whether LCN2 could be a potential biomarker for PH in pediatric patients who underwent surgery for CHD. From December 2018 to February 2020, patients undergoing surgical repair for congenital defects with and without PH were identified. Healthy children without CHD and PH served as controls. A mean pulmonary artery pressure (mPAP) >20 mmHg was used as the definition of PH. Blood samples and echocardiograms were obtained in all patients and right heart catheterization was performed in 79 patients. Multivariable logistic regression analysis was used to determine potential predictors for PH. Among 102 patients, the median age was 10 [Interquartile range (IQR) 7.0-13] months, and 37.5% were female. Compared to non-PH patients and controls, PH patients showed elevated levels of LCN2 (P < 0.001). In addition, LCN2 levels positively correlated with the invasive haemodynamic indices of PH. In univariate regression, LCN2 (odds ratio = 2.69 [1.06-5.31], P < 0.001), N-Terminal pro Brain Natriuretic Peptide (NT-proBNP) (OR = 1.91 [1.21-7.56], P = 0.03) and high-sensitive troponin T (hsTnT) (OR = 1.36 [1.01-3.57], P = 0.01) were associated with PH; however, only LCN2 (OR = 1.68 [1.04-4.52], P = 0.03) was significantly associated with PH on multivariate analysis. In conclusion, children with PH had increased LCN2 expression. LCN2 levels positively correlated with invasive indices of PH. These results indicate LCN2 could be a useful biomarker for prediction of PH in pediatric CHD cases.

Abstract
Thirty-eight-year-old male presented for evaluation of abdominal swelling, lower extremity edema and dyspnea on exertion. Extensive work-up in search of the culprit etiology revealed the presence of an Anomalous Right Upper Pulmonary Venous Return (ARUPVR) into the Superior Vena Cava (SVC). During the attempted repair, the pericardium was found to be thickened and constrictive. Only one other case of co-existent partial anomalous pulmonary venous return and constrictive pericarditis (CP) has been reported. The patient underwent a warden procedure with pericardial stripping with good outcomes at 45 days post-operatively. Thus, the presence of severe heart failure symptoms in the setting of ARUPVR should prompt further investigations. Also, further cases are needed to help guide management in these patients.

Abstract
Negative stress echocardiography (NSE) is associated with low cardiovascular morbidity and overall mortality. We aimed to determine the clinical and echocardiographic predictors of overall and cardiovascular outcomes following NSE. Patients who underwent SE between 2013 and 2017 were reviewed. Patients with a history of solid organ transplant or being evaluated for transplant, history of end-stage renal or liver disease, and positive SE were excluded. NSE results were divided into negative diagnostic if patient reached target heart rate (THR) and had no wall motion abnormality (WMA) at rest or stress; negative non-diagnostic if patient had no WMA but did not reach THR or if image quality was non-diagnostic; and abnormal non-ischemic if patient had a resting WMA not worsened at stress along with a personal history of coronary artery disease (CAD). New CAD lesion at 1 year was defined as ≥ 50% stenosis on cardiac catheterization. Of 4119 patients with SE, 2575 were included. All-cause mortality rate was 1.1%/year and CAD rate was 3.1%/year. Predictors of all-cause mortality were age, male gender, history of smoking and being selected for dobutamine SE. Predictors of a new CAD lesion at 1 year were male gender, diabetes, personal history of CAD and abnormal non-ischemic SE. We identified clinical and echocardiographic characteristics in a subset of NSE patients who are at higher risk for subsequent adverse events. These characteristics should be accounted for during the clinical interpretation of SE, and patients found at increased risk for morbidity and mortality warrant continued follow-up.
