RESUMEN
BACKGROUND AND AIMS: For patients with symptomatic, severe tricuspid regurgitation (TR), early results of transcatheter tricuspid valve (TV) intervention studies have shown significant improvements in functional status and quality of life associated with right-heart reverse remodelling. Longer-term follow-up is needed to confirm sustained improvements in these outcomes. METHODS: The prospective, single-arm, multicentre TRISCEND study enrolled 176 patients to evaluate the safety and performance of transcatheter TV replacement in patients with ≥moderate, symptomatic TR despite medical therapy. Major adverse events, reduction in TR grade and haemodynamic outcomes by echocardiography, and clinical, functional, and quality-of-life parameters are reported to one year. RESULTS: Enrolled patients were 71.0% female, mean age 78.7 years, 88.0% ≥ severe TR, and 75.4% New York Heart Association classes III-IV. Tricuspid regurgitation was reduced to ≤mild in 97.6% (P < .001), with increases in stroke volume (10.5 ± 16.8â mL, P < .001) and cardiac output (0.6 ± 1.2â L/min, P < .001). New York Heart Association class I or II was achieved in 93.3% (P < .001), Kansas City Cardiomyopathy Questionnaire score increased by 25.7 points (P < .001), and six-minute walk distance increased by 56.2â m (P < .001). All-cause mortality was 9.1%, and 10.2% of patients were hospitalized for heart failure. CONCLUSIONS: In an elderly, highly comorbid population with ≥moderate TR, patients receiving transfemoral EVOQUE transcatheter TV replacement had sustained TR reduction, significant increases in stroke volume and cardiac output, and high survival and low hospitalization rates with improved clinical, functional, and quality-of-life outcomes to one year.

BACKGROUND: Residual shunt is observed in up to 25% of patients after patent foramen ovale (PFO) closure, but its long-term influence on stroke recurrence currently is unknown. OBJECTIVE: To investigate the association of residual shunt after PFO closure with the incidence of recurrent stroke and transient ischemic attack (TIA). DESIGN: Prospective cohort study comparing stroke or TIA recurrence in patients with and without residual shunt after PFO closure. SETTING: Single hospital center. PARTICIPANTS: 1078 consecutive patients (mean age, 49.3 years) with PFO-attributable cryptogenic stroke who were undergoing percutaneous PFO closure were followed for up to 11 years. MEASUREMENTS: Residual shunt was evaluated by transthoracic echocardiography with saline contrast. Primary outcome was a composite of the first recurrent ischemic stroke or TIA after PFO closure. RESULTS: Compared with complete closure, the presence of residual shunt after PFO closure was associated with an increased incidence of recurrent stroke or TIA: 2.32 versus 0.75 events per 100 patient-years (hazard ratio [HR], 3.05 [95% CI, 1.65 to 5.62]; P < 0.001). This result remained robust after adjustment for important covariates, namely age; study period; device; presence of atrial septal aneurysm, hypertension, hyperlipidemia, diabetes, hypercoagulability, or hypermobile septum; and medication use (HR, 3.01 [CI, 1.59 to 5.69]; P < 0.001). Further stratification based on shunt size revealed that moderate or large residual shunts were associated with a higher risk for stroke or TIA recurrence (HR, 4.50 [CI, 2.20 to 9.20]; P < 0.001); the result for small residual shunts was indeterminate (HR, 2.02 [CI, 0.87 to 4.69]; P = 0.102). LIMITATION: Nonrandomized study with potential unmeasured confounding. CONCLUSION: Among patients undergoing PFO closure to prevent future stroke, the presence of residual shunt, particularly a moderate or large residual shunt, was associated with an increased risk for stroke or TIA recurrence.

We report a case of acute aorto-right ventricular fistula following transcatheter bicuspid aortic valve replacement and subsequent percutaneous closure. The diagnosis and treatment of this rare complication is illustrated through multi-modality imaging. We hypothesize that the patient's heavily calcified bicuspid aortic valve anatomy led to asymmetric deployment of the transcatheter aortic valve replacement (TAVR) prosthesis, traumatizing the right sinus of Valsalva at the distal edge of the TAVR stent and ultimately fistulized to the right ventricle. The patient acutely decompensated with heart failure five days after TAVR and underwent emergent intervention. The aorto-right ventricular fistula was closed using an 18-mm septal occluder device with marked clinical recovery. Transcatheter closure is a viable treatment option for acute aorto-right ventricular fistula. © 2016 Wiley Periodicals, Inc.

This case report discusses a 42-year-old male with dextro-transposition of the great arteries (D-TGA) status post Mustard repair and sick sinus syndrome status post dual-chamber pacemaker implant, who developed symptomatic superior vena cava (SVC) baffle stenosis. He was treated with a combined pacemaker extraction and subsequent SVC baffle stenting. The case highlights the complexities of treating SVC baffle stenosis in the presence of cardiac implantable devices and demonstrates the efficacy of this combined approach. Furthermore, the authors delve into the intricacies of D-TGA, its surgical history, and the long-term complications associated with atrial switch procedures.

RESUMEN
BACKGROUND: Mitral valve transcatheter edge-to-edge repair is safe and effective in treating degenerative mitral regurgitation (DMR) patients at prohibitive surgical risk, but outcomes in complex mitral valve anatomy patients vary. OBJECTIVES: The PASCAL IID registry assessed safety, echocardiographic, and clinical outcomes with the PASCAL system in prohibitive risk patients with significant symptomatic DMR and complex mitral valve anatomy. METHODS: Patients in the prospective, multicenter, single-arm registry had 3+ or 4+ DMR, were at prohibitive surgical risk, presented with complex anatomic features based on the MitraClip instructions for use, and were deemed suitable for the PASCAL system by a central screening committee. Enrolled patients were treated with the PASCAL system. Safety, effectiveness, and functional and quality-of-life outcomes were assessed. Study oversight also included an echocardiographic core laboratory and clinical events committee. RESULTS: The study enrolled 98 patients (37.2% ≥2 independent significant jets, 15.0% severe bileaflet/multi scallop prolapse, 13.3% mitral valve orifice area <4.0 cm2, and 10.6% large flail gap and/or large flail width). The implant success rate was 92.9%. The 30-day composite major adverse event rate was 11.2%. At 6 months, 92.4% patients achieved MR ≤2+ and 56.1% achieved MR ≤1+ (P < 0.001 vs baseline). The Kaplan-Meier estimates for survival, freedom from major adverse events, and heart failure hospitalization at 6 months were 93.7%, 85.6%, and 92.6%, respectively. Patients experienced significant symptomatic improvement compared with baseline (P < 0.001). CONCLUSIONS: The outcomes of the PASCAL IID registry establish the PASCAL system as a useful therapy for prohibitive surgical risk DMR patients with complex mitral valve anatomy.

BACKGROUND: Favorable 6-month outcomes from the CLASP IID Registry (Edwards PASCAL transcatheter valve repair system pivotal clinical trial) demonstrated that mitral valve transcatheter edge-to-edge repair with the PASCAL transcatheter valve repair system is safe and beneficial for treating prohibitive surgical risk degenerative mitral regurgitation (DMR) patients with complex mitral valve anatomy. OBJECTIVES: The authors sought to assess 1-year safety, echocardiographic and clinical outcomes from the CLASP IID Registry. METHODS: Patients with 3+ or 4+ DMR who were at prohibitive surgical risk, had complex mitral valve anatomy based on the MitraClip Instructions for Use, and deemed suitable for treatment with the PASCAL system were enrolled prospectively. Safety, clinical, echocardiographic, functional, and quality-of-life outcomes were assessed at 1 year. Study oversight included a central screening committee, echocardiographic core laboratory, and clinical events committee. RESULTS: Ninety-eight patients were enrolled. One-year Kaplan-Meier (KM) estimates of freedom from composite major adverse events, all-cause mortality, and heart failure hospitalization were 83.5%, 89.3%, and 91.5%, respectively. Significant mitral regurgitation (MR) reduction was achieved at 1 year (P < 0.001 vs baseline) including 93.2% at MR ≤2+ and 57.6% at MR ≤1+ with improvements in related echocardiographic measures. NYHA functional class and Kansas City Cardiomyopathy Questionnaire score also improved significantly (P < 0.001 vs baseline). CONCLUSIONS: At 1 year, treatment with the PASCAL system demonstrated safety and significant MR reduction, with continued improvement in clinical, echocardiographic, functional, and quality-of-life outcomes, illustrating the value of the PASCAL system in the treatment of prohibitive surgical risk patients with 3+ or 4+ DMR and complex mitral valve anatomy.

BACKGROUND: The CLASP IID (Edwards PASCAL TrAnScatheter Valve RePair System Pivotal Clinical) trial is the first randomized controlled trial comparing the PASCAL system and the MitraClip system in prohibitive risk patients with significant symptomatic degenerative mitral regurgitation (DMR). OBJECTIVES: The study sought to report primary and secondary endpoints and 1-year outcomes for the full cohort of the CLASP IID trial. METHODS: Prohibitive-risk patients with 3+/4+ DMR were randomized 2:1 (PASCAL:MitraClip). One-year assessments included secondary effectiveness endpoints (mitral regurgitation [MR] ≤2+ and MR ≤1+), and clinical, echocardiographic, functional, and quality-of-life outcomes. Primary safety (30-day composite major adverse events [MAE]) and effectiveness (6-month MR ≤2+) endpoints were assessed for the full cohort. RESULTS: Three hundred patients were randomized (PASCAL: n = 204; MitraClip: n = 96). At 1 year, differences in survival, freedom from heart failure hospitalization, and MAE were nonsignificant (P > 0.05 for all). Noninferiority of the PASCAL system compared with the MitraClip system persisted for the primary endpoints in the full cohort (For PASCAL vs MitraClip, the 30-day MAE rates were 4.6% vs 5.4% with a rate difference of -0.8% and 95% upper confidence bound of 4.6%. The 6-month MR≤2+ rates were 97.9% vs 95.7% with a rate difference of 2.2% and 95% lower confidence bound (LCB) of -2.5%, for, respectively). Noninferiority was met for the secondary effectiveness endpoints at 1 year (MR≤2+ rates for PASCAL vs MitraClip were 95.8% vs 93.8% with a rate difference of 2.1% and 95% LCB of -4.1%. The MR≤1+ rates were 77.1% vs 71.3% with a rate difference of 5.8% and 95% LCB of -5.3%, respectively). Significant improvements in functional classification and quality of life were sustained in both groups (P <0.05 for all vs baseline). CONCLUSIONS: The CLASP IID trial full cohort met primary and secondary noninferiority endpoints, and at 1 year, the PASCAL system demonstrated high survival, significant MR reduction, and sustained improvements in functional and quality-of-life outcomes. Results affirm the PASCAL system as a beneficial therapy for prohibitive-surgical-risk patients with significant symptomatic DMR.
RESUMEN
Background: Although surgical repair was the traditional first-line treatment for native coarctation of the aorta (CoA), balloon angioplasty (BA) and stenting are now increasingly being performed. We aimed to determine the practice patterns and acute outcomes of transcatheter interventions for native coarctation in the largest multicenter registry for congenital catheterization. Methods: CoA interventions from the IMPACT (IMproving Pediatric and Adult Congenital Treatment) National Cardiovascular Data Registry were analyzed. The procedure choice and acute outcomes were compared among patients with no prior interventions on the aortic isthmus (native CoA). Procedural success was defined as no major adverse events (MAEs) and a final peak gradient of <20 mm Hg and optimal outcome as no MAEs and a final gradient of <10 mm Hg. Results: Over the 8-year study period, 5928 CoA procedures were performed, of which 1187 were performed in patients with native CoA. In this group, stenting was performed in more then half of children aged >1 year and >90% of those aged >8 years. Procedural success was achieved in >90% of stenting procedures but in only 69% of BAs. Stent implantation was associated with a higher likelihood of optimal gradient (<10 mm Hg) after adjustment for age and baseline characteristics. MAEs were most common in children aged <1 year (14%), occurred in 2% to 2.5% of those aged 1 to 18 years and in 6.6% of adults (P < .001), and were more likely after BA than after stenting (odds ratio, 0.5; 95% CI, 0.28-0.9; unadjusted P = .02). Conclusions: Catheter interventions for native coarctation are performed safely in older children and adults, with a high degree of immediate procedural success, particularly with stenting.
RESUMEN
BACKGROUND: Severe symptomatic degenerative mitral regurgitation (DMR) has a poor prognosis in the absence of treatment, and new transcatheter options are emerging. OBJECTIVES: The CLASP IID (Edwards PASCAL Transcatheter Valve Repair System Pivotal Clinical Trial) randomized trial (NCT03706833) is the first to evaluate the safety and effectiveness of the PASCAL system compared with the MitraClip system in patients with significant symptomatic DMR. This report presents the primary safety and effectiveness endpoints for the trial. METHODS: Patients with 3+ or 4+ DMR at prohibitive surgical risk were assessed by a central screening committee and randomized 2:1 (PASCAL:MitraClip). Study oversight also included an echocardiography core laboratory and a clinical events committee. The primary safety endpoint was the composite major adverse event rate at 30 days. The primary effectiveness endpoint was the proportion of patients with mitral regurgitation (MR) ≤2+ at 6 months. RESULTS: A prespecified interim analysis in 180 patients demonstrated noninferiority of the PASCAL system vs the MitraClip system for the primary safety and effectiveness endpoints of major adverse event rate (3.4% vs 4.8%) and MR ≤2+ (96.5% vs 96.8%), respectively. Functional and quality-of-life outcomes significantly improved in both groups (P < 0.05). The proportion of patients with MR ≤1+ was durable in the PASCAL group from discharge to 6 months (PASCAL, 87.2% and 83.7% [P = 0.317 vs discharge]; MitraClip, 88.5% and 71.2% [P = 0.003 vs discharge]). CONCLUSIONS: The CLASP IID trial demonstrated safety and effectiveness of the PASCAL system and met noninferiority endpoints, expanding transcatheter treatment options for prohibitive surgical risk patients with significant symptomatic DMR.

OBJECTIVE: To analyze the differences in anatomical, clinical and echocardiographic characteristics of women and men undergoing PMV and to evaluate the relationship between sex, PMV success, and immediate and long-term clinical outcome. BACKGROUND: Rheumatic mitral stenosis (MS) is predominantly a disease of middle-aged women. Percutaneous mitral valvuloplasty (PMV) has become the standard of care for suitable patients. However little is known about the relationship between sex, PMV success, and procedural outcome. METHODS AND RESULTS: We evaluated measures of procedural success and clinical outcome in consecutive patients (839 women and 176 men) who underwent PMV. Despite a lower baseline echocardiographic score (7.47 ± 2.15 vs. 8.02 ± 2.18, P = 0.002), women were less likely to achieve PMV success (69% vs. 83%, adjusted OR 0.44, 95% CI 0.27-0.74, P = 0.002), and had a smaller post-procedural MV area (1.86 ± 0.7 vs. 2.07 ± 0.7 cm(2), P < 0.001). Overall procedural and in-hospital complication rates did not differ significantly between women and men. However, women were significantly more likely to develop severe MR immediately post PMV (adjusted OR 2.41, 95% CI 1.0-5.83, P = 0.05) and to undergo MV surgery (adjusted HR 1.54, 95% CI 1.03-2.3, P = 0.037) after a median follow-up of 3.1 years. CONCLUSIONS: Compared to men, women with rheumatic MS who undergo PMV are less likely to have a successful outcome and more likely to require MV surgery on long-term follow-up despite more favorable baseline MV anatomy.

OBJECTIVE: To determine the influence of patent foramen ovale (PFO) closure on circulatory biomarkers. METHODS: Consecutive patients with PFO-related stroke were prospectively enrolled and followed with serial sampling of cardiac atrial and venous blood pre- and post-PFO closure over time. Candidate biomarkers were identified by mass spectrometry in a discovery cohort first, and lead candidates were validated in an independent cohort. RESULTS: Patients with PFO-related stroke (n = 254) were recruited and followed up to 4 years (median 2.01; interquartile range 0.77-2.54). Metabolite profiling in the discovery cohort (n = 12) identified homocysteine as the most significantly decreased factor in intracardiac plasma after PFO closure (false discovery rate 0.001). This was confirmed in a validation cohort (n = 181), where intracardiac total homocysteine (tHcy) was immediately reduced in patients with complete closure, but not in those with residual shunting, suggesting association of PFO shunting with tHcy elevation (ß 0.115; 95% confidence interval [CI] 0.047-0.183; p = 0.001). tHcy reduction was more dramatic in left atrium than right (p < 0.001), suggesting clearance through pulmonary circulation. Long-term effect of PFO closure was also monitored and compared to medical treatment alone (n = 61). Complete PFO closure resulted in long-term tHcy reduction in peripheral blood, whereas medical therapy alone showed no effect (ß -0.208; 95% CI -0.375â¼-0.058; p = 0.007). Residual shunting was again independently associated with persistently elevated tHcy (ß 0.184; 95% CI 0.051-0.316; p = 0.007). CONCLUSIONS: PFO shunting may contribute to circulatory tHcy elevation, which is renormalized by PFO closure. PFO is not just a door for clots, but may itself enhance clot formation and injure neurovasculature by clot-independent mechanisms. Biomarkers such as tHcy can potentially serve as cost-effective measures of residual shunting and neurovascular risk for PFO stroke.

OBJECTIVES: The aim of this study was to investigate the effect of management on the risk for recurrent events among patients with cryptogenic ischemic stroke or transient ischemic attack. BACKGROUND: The combination of patent foramen ovale (PFO) and hypercoagulability may greatly increase the risk for paradoxical embolism. However, previous randomized controlled trials evaluating the efficacy of PFO closure excluded these potential high-risk patients. METHODS: Patients diagnosed with PFO attributable cryptogenic embolism were prospectively, without randomization, recruited from January 2005 to March 2018. The relationship between thrombophilia and recurrent events was evaluated in overall patients. Multivariate Cox regression was conducted to assess the relative risk for recurrence in PFO closure and medical therapy groups. RESULTS: A total of 591 patients with cryptogenic embolism with PFO were identified. The median duration of follow-up was 53 months, and thrombophilia significantly increased the risk for recurrent events (hazard ratio [HR]: 1.85; 95% confidence interval [CI]: 1.09 to 3.16; p = 0.024). PFO closure was superior to medical therapy in overall patients (HR: 0.16; 95% CI: 0.09 to 0.30; p < 0.001). Of the 134 patients (22.7%) with thrombophilia, there was a difference in the risk for recurrence events between the PFO closure (6 of 89) and medical therapy (15 of 45) groups (HR: 0.25; 95% CI: 0.08 to 0.74; p = 0.012). There was no potential heterogeneity in the further subgroup analysis. CONCLUSIONS: Patients with cryptogenic stroke with PFO and hypercoagulable state had increased risk for recurrent stroke or transient ischemic attack. PFO closure provided a lower risk for recurrent events compared with medical therapy alone.

Native heart endomyocardial biopsy (NH-EMB) is an infrequently performed procedure. The objective of this study is to describe utilization trends, indications, and complications associated with NH-EMB in the United States and compare them with transplanted heart endomyocardial biopsy (TH-EMB). Using the Healthcare Cost and Utilization Project National Inpatient Sample database, we identified 71,105 adult patients undergoing EMB in the inpatient setting in participating hospitals from 2002 to 2014. A total of 20,770 (29%) were performed on NHs (mean age 52.2 ± 15.3, 61% men). Approximately half of patients were white and mean Charlson co-morbidity index was 1.97 ± 1.6. Common indications for NH-EMB included a suspected primary cardiomyopathy (disorder confined to the myocardium), heart failure without cardiogenic shock, and acute myocarditis. Less common indications included heart failure with cardiogenic shock, unexplained heart failure with ventricular tachycardia or high-degree atrioventricular block, and cardiac neoplasms. Complications included pericardial effusion (3.8%), third-degree atrioventricular block (2.7%), vascular complications (1.9%), and deep venous thrombosis (3.5%), in others. Predictors of complications included presence of a cardiac malignant neoplasm, use of hemodynamic support, heart failure with ventricular tachyarrhythmias, and female gender. Compared with NH-EMB, TH-EMB was associated with lower rates of pericardial effusion, third-degree atrioventricular block, ventricular tachyarrhythmias requiring cardioversion, and higher rates of deep venous thrombosis, infections, and pneumothorax. NH-EMB utilization is low in the United States and constitutes less than 1/3 of all EMBs performed.

PURPOSE OF REVIEW: The goal of this review is to discuss the effects of Impella (Abiomed, Danvers, MA), to support in the hemodynamics of patients with severe aortic stenosis, and to explore the clinical scenarios in which the use of Impella may be beneficial in this setting. RECENT FINDINGS: The management of patients with severe aortic stenosis who go on to develop left ventricular failure and cardiogenic shock remains an important clinical challenge associated with increased morbidity and mortality. Once considered a relative contraindication, the use of Impella in severe aortic stenosis has now been proven feasible and demonstrated promising results in selected high-risk patients. The use of Impella to provide hemodynamic support maybe considered in patients with aortic stenosis in cardiogenic shock or those with severe left ventricular dysfunction and CAD who require high-risk PCI and or balloon aortic valvuloplasty. Impella is also an attractive option in selected cases of hemodynamic collapse during TAVR.
RESUMEN
BACKGROUND: Ventricular septal defect is a lethal complication after an acute myocardial infarction, which has become infrequent with the advent of reperfusion strategies; however, it remains a major contributor to mortality. METHODS: We identified patients using the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes from the Nationwide Inpatient Sample between the years 2001 and 2013. A multivariate hierarchical logistic regression model was used to identify significant predictors of in-hospital mortality. RESULTS: We identified 3,373,206 ST-elevation myocardial infarctions, out of which 10,012 (0.3%) were complicated with ventricular septal defects. Most of the patients (60%) were older than 65 years, male (55%), and white (63%). Inferior (49.7%) and anterior (41.1%) myocardial infarctions were more commonly implicated with the development of ventricular septal defects. The median (interquartile range) hospitalization length was 7 (3.0-13.5) days. Only 7.65% of patients underwent some intervention, with 7% surgical and 0.65% minimally invasive. Mechanical support devices were used in 36.5% of patients, with intra-aortic balloon pump (96%) being the most common. In-hospital mortality remained high at 30.5% (downward trending from 41.6% in 2001 to 23.3% in 2013). Age, cardiogenic shock, and in-hospital cardiac arrest were statistically significant predictors of in-hospital mortality. The utilization of corrective procedures significantly declined. The use of mechanical support devices and performing a corrective procedure were associated with higher mortality, length of stay, and cost. CONCLUSIONS: Ventricular septal defects after acute myocardial infarctions remain associated with significantly high mortality rates. Highly specialized regional centers with individual expertise in the management of septal ruptures are required to improve outcomes of these patients.
