RESUMEN
Nowadays, the long-life management of patients with aortic stenosis has emerged as one of the most debated issues. Transcatheter aortic valve replacement is more frequently performed in younger patients with lower surgical risk, and also the number of valve-in-valve (ViV) procedures has increased in the last few years. However, coronary obstruction is the most dreadful complication related to this procedure. To prevent coronary obstruction in the context of transcatheter aortic ViV implantation, the BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) technique was developed. Although effective, BASILICA is complex and time-consuming. Hence, simpler, reproducible, and faster strategies are desirable. Here we present a promising simplified BASILICA technique employing an Armada Balloon to perform the leaflet laceration.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is a rare but potentially lethal complication. Main mechanisms are sinus insufficiency or sinus sequestration with well-described risk factors. We present two cases of acute right coronary artery occlusion during TAVI with a self-expanding valve in the absence of classical risk factors and propose a novel mechanism.

We present the first documented case of a successful closure of a transcatheter aortic valve replacement (TAVR)-induced Gerbode defect using a valve-in-valve approach. A 90-year-old female with severe aortic stenosis underwent TAVR. Following post-dilatation, the patient experienced hemodynamic deterioration and collapse due to tamponade and sub-annular rupture leading to hemodynamic deterioration and the development of a Gerbode defect with communication between the left ventricle and right atrium. Hemodynamic stabilization was achieved through pericardiocentesis, followed by the low implantation of a second valve, effectively sealing the rupture. This case showcases a valuable alternative for managing rare challenging complications during TAVR procedures.

The Harmony™ Transcatheter Pulmonary Valve (Medtronic) was recently approved by the Food and Drug Administration for transcatheter pulmonary valve replacement in native right ventricular outflow tracts. Despite this milestone, some patients have main pulmonary arteries that are severely dilated and continue to require surgical pulmonary valve replacement. The hybrid approach combines surgical creation of a landing zone, transcatheter valve deployment, and suture stabilization of the implanted valve. In this case series, we report the first use of a hybrid approach for Harmony™ transcatheter pulmonary valve replacement. Two cases are reported with varying approaches for surgical creation of a landing zone followed by successful placement of a Harmony™ valve.

Aortic regurgitation (AR) is associated with morbidity and premature mortality. Surgical aortic valve replacement is not an option for many patients due to an adverse surgical risk profile, whilst transcatheter aortic valve implantation with most available prostheses has demonstrated suboptimal implantation success and outcomes. The JenaValve Trilogy™ system provides an attractive solution for such patients as it utilizes clips that directly attach onto the native valve leaflets to anchor. Initially designed for transapical delivery, the current transfemoral delivery system is under investigation in the United States and approved for aortic stenosis and regurgitation in Europe. We present an expert review on the technical aspects of the Trilogy system, provide a guide for implantation, discuss the available evidence for the technology and provide illustrative case examples.
RESUMEN
Transcatheter aortic valve implantation (TAVI) is recommended for a growing range of patients with severe aortic stenosis in the European Society of Cardiology and European Association for Cardio-Thoracic Surgery (ESC/EACTS) 2021 Guidelines update. However, guideline implementation programs are needed to ensure the application of clinical recommendations which will favorably influence disease outcomes. An Expert Council was convened to identify whether cardiology services across Europe are set up to address the growing needs of patients with severe aortic stenosis for increased access to TAVI by identifying the key challenges faced in growing TAVI programs and mapping associated solutions. Wide variation exists across Europe in terms of TAVI availability and capacity to deliver the increased demand for TAVI in different countries. The recommendations of this Expert Council focus on the short-to-medium-term aspects where the most immediate, actionable impact can be achieved. The focus on improving procedural efficiency and optimizing the patient pathway via clinical practice and patient management demonstrates how to mitigate the current major issues of shortfall in catheterization laboratory, workforce, and bed capacity. Procedural efficiencies may be achieved through steps including streamlined patient assessment, the benchmarking of standards for minimalist procedures, standardized approaches around patient monitoring and conduction issues, and the implementation of nurse specialists and dedicated TAVI coordinators to manage organization, logistics, and early mobilization. Increased collaboration with wider stakeholders within institutions will support successful TAVI uptake and improve patient and economic outcomes. Further, increased education, collaboration, and partnership between cardiology centers will facilitate sharing of expertise and best clinical practice.

OBJECTIVE: The objective of this study was to evaluate the incidence of and risk factors associated with cardiogenic shock (CS) following surgery versus transcatheter tricuspid valve intervention (TTVI) for tricuspid regurgitation (TR). BACKGROUND: Surgical therapy for TR is associated with high rates of CS. Postprocedural shock has not been studied following TTVI. METHODS: We performed a single-center retrospective analysis of isolated tricuspid valve (TV) surgery or TTVI for TR. The primary outcome was postprocedural class D or E CS according to Society for Cardiovascular Angiography and Interventions (SCAI) CS classification scheme, and secondary outcome was in-hospital mortality. Multivariable logistic regression modeling was performed for primary and secondary outcomes. Support vector machine analysis was performed for sensitivity analysis. RESULTS: From 2008 to 2020, a total of 122 patients underwent isolated TV surgery (n = 58, 14 TV repair, and 44 TV replacement) or TTVI (n = 64, 36 TV repair, and 28 TV replacement). Surgical patients were significantly younger than TTVI patients (67.5 vs. 80 years, p < 0.0001). Multivariable modeling revealed an association between the primary outcome and surgery (odds ratio [OR]: 8.75, 95% confidence interval [CI]: 2.83, 27.03, p = 0.0002), as well as baseline central venous pressure (CVP, OR: 1.12, 95% CI: 1.02, 1.22, p = 0.016). Additionally, class DE CS was independently associated with in-hospital mortality (OR: 5.21, 1.35, 20.09, p = 0.016). CVP and surgery were found to have highest importance indices in support vector machine analysis. CONCLUSION: In patients undergoing TV intervention for TR, surgery versus TTVI and elevated CVP are associated with advanced postprocedural CS. Patients developing advanced CS are at increased risk of in-hospital mortality.

Prosthetic valve endocarditis (PVE) following transcatheter aortic valve replacement (TAVR) in low surgical risk patients is uncommon, occurring in 11 of 396 patients (2.8%) in the study by Medranda et al., but associated with high morbidity (6 of 11 with embolic strokes [55%]) and mortality (2 of 11 [18%]). As TAVR volumes increase, especially in low surgical risk patients, whose long-term outcomes are generally excellent, PVE will become an increasingly important concern. Future research is needed to identify optimal strategies for prevention, diagnosis, and treatment of PVE associated with TAVR.

Despite advances in transcatheter aortic valve replacement (TAVR) technology, periprocedural stroke remains a complication of TAVR procedures. The TriGUARD 3 device is designed to be positioned in the aortic arch to deflect debris away from the brachiocephalic, left common carotid, and left subclavian arteries during TAVR. The United States Food and Drug Administration (FDA) assembled the Circulatory System Devices Panel to review safety and effectiveness data for the TriGUARD 3 device. Because of the coronavirus disease 2019 pandemic, this meeting was held virtually. In this manuscript, we summarize the data presented by both the sponsor and FDA, as well as the panel discussion.

OBJECTIVES: To investigate the efficacy and safety of larger valve sizing beyond the commercially recommended annular range in transcatheter aortic valve replacement (TAVR) with balloon-expandable transcatheter heart valve (THVs). BACKGROUND: The clinical implications of larger balloon-expandable THV implantation with underfilling are poorly evaluated. METHODS: This retrospective study included 692 consecutive patients who underwent TAVR with SAPIEN3. A total of 271 patients who underwent SAPIEN 3 implantation were analyzed based on three border zones (Zone 1: 300-345 mm2 , 23 vs. 20 mm; Zone 2: 400-430 mm2 , 26 vs. 23 mm; Zone 3: 500-546 mm2 , 29 vs. 26 mm). The primary endpoint was the effective orifice area (EOA) assessed by echocardiography at 1 year, and secondary endpoints were a 30-day mortality rate, procedural complications during TAVR, and a composite of death from any cause and heart failure requiring rehospitalization at 1 year. RESULTS: At 1-year follow-up, the EOA in the larger valve groups was greater than that in the recommended valve group in each zone (Zone 1: 1.45 ± 0.03 vs. 1.06 ± 0.06 cm2 , p < 0.001; Zone 2: 1.83 ± 0.05 vs. 1.41 ± 0.05 cm2 , p < 0.001; Zone 3: 1.93 ± 0.07 vs. 1.69 ± 0.07 cm2 , p = 0.02). No significant difference in the secondary endpoint was observed in any of the zones. CONCLUSIONS: Implantation of the out-of-range larger SAPIEN 3 THVs with underfilling was associated with greater EOA at the 1-year follow-up and feasible in the selected patients.

Crossover balloon occlusion technique (CBOT) has been proposed to ensure adequate closure of the arterial access used for transcatheter aortic valve replacement (TAVR). However, the CBOT performed through the contralateral femoral artery could be challenging in cases of excessively tortuous and calcified vessels or in the presence of narrow iliac carina angles. We describe a novel technique to facilitate the advancement the peripheral balloon through the contralateral femoral artery up to the target iliofemoral system in order to facilitate access site hemostasis. The present "locking and drugging" technique takes advantages from two mechanical aspects: (a) the locking of the 0.018â³ wire between the vessel wall and the TAVR delivery system or the dedicated sheath, which facilitate the crossover of the balloon in the contralateral iliofemoral system, preventing its prolapse into the aorta at the carina level and (b) the dragging of the balloon advanced into the contralateral iliofemoral system during the retrieve of the TAVR delivery system or the dedicated sheath.

BACKGROUND: During COVID-19 pandemic in Spain, elective procedures were canceled or postponed, mainly due to health care systems overwhelming. OBJECTIVE: The objective of this study was to evaluate the consequences of interrupting invasive procedures in patients with chronic cardiac diseases due to the COVID-19 outbreak in Spain. METHODS: The study population is comprised of 2,158 patients that were pending on elective cardiac invasive procedures in 37 hospitals in Spain on the 14th of March 2020, when a state of alarm and subsequent lockdown was declared in Spain due to the COVID-19 pandemic. These patients were followed-up until April 31th. RESULTS: Out of the 2,158 patients, 36 (1.7%) died. Mortality was significantly higher in patients pending on structural procedures (4.5% vs. 0.8%, respectively; p < .001), in those >80 year-old (5.1% vs. 0.7%, p < .001), and in presence of diabetes (2.7% vs. 0.9%, p = .001), hypertension (2.0% vs. 0.6%, p = .014), hypercholesterolemia (2.0% vs. 0.9%, p = .026) [Correction added on December 23, 2020, after first online publication: as per Dr. Moreno's request changes in p-values were made after original publication in Abstract.], chronic renal failure (6.0% vs. 1.2%, p < .001), NYHA > II (3.8% vs. 1.2%, p = .001), and CCS > II (4.2% vs. 1.4%, p = .013), whereas was it was significantly lower in smokers (0.5% vs. 1.9%, p = .013). Multivariable analysis identified age > 80, diabetes, renal failure and CCS > II as independent predictors for mortality. CONCLUSION: Mortality at 45 days during COVID-19 outbreak in patients with chronic cardiovascular diseases included in a waiting list due to cancellation of invasive elective procedures was 1.7%. Some clinical characteristics may be of help in patient selection for being promptly treated when similar situations happen in the future.

OBJECTIVES: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) are associated with adverse outcomes in severe aortic stenosis (AS) patients. Our aim was to evaluate the association between ≥moderate TR and RV dysfunction on long-term mortality following transcatheter aortic valve replacement (TAVR). METHODS: A retrospective analysis of the Israeli multicenter TAVR registry among 4,344 consecutive patients, with all-cause mortality as the main outcome measure. RESULTS: Echocardiographic assessment of TR grade and RV dysfunction was available for 3,733 and 1,850 patients, of whom ≥moderate TR and RV dysfunction was noted for 478(13%) and 78(4%), respectively. The mean follow-up time was 2.9 ± 2.3 years. In univariate models, ≥Moderate TR and ≥moderate RV dysfunction were associated with increased long-term mortality (HR 1.45, 95% CI 1.24-1.69, p < .001 and HR 1.73, 95% CI 1.21-2.47, p = 0.003, respectively). These finding did not remained significant after adjusting to echocardiographic parameters. A subset of patients with no improvement in RV function had the highest long-term mortality risk (HR 3.3, 95% CI 1.95-5.7, p < .001). CONCLUSION: When adjusted to multiple echocardiographic characteristics baseline ≥Moderate TR and ≥moderate RV dysfunction were not associated with long-term mortality following TAVR. Persistent RV dysfunction following TAVR was associated with the highest risk for mortality.

OBJECTIVES: To compare the incidence of permanent pacemaker implantation (PPI) with the CoreValve and Evolut R prostheses, to evaluate the implantation depth with both types of prostheses, and to study factors predicting the need for PPI. BACKGROUND: The Evolut R CoreValve can be recaptured and repositioned during deployment, allowing a more precise implantation. METHODS: A total of 208 patients treated with CoreValve and 137 patients treated with Evolut R were analyzed. The depth of the prosthesis in the LVOT was measured by angiography in the annular perpendicular view projection after deploymen in all patients. RESULTS: Baseline conduction abnormalities were comparable between the groups (85/208, 40.9% vs. 53/137, 38.7%; p = 0.69). The mean prosthesis depth was 10.3 ± 8.6 mm in the CoreValve group and 5.5 ± 2.7 mm in the Evolut R group; p < 0.0001. Conduction disturbances after valve implantation were more frequent with the CoreValve (new-onset left bundle branch block: 93, 44.7% vs. 16, 11.7%; p < 0.05, first-degree atrioventricular block: 23, 11.1% vs. 5, 3.6%; p < 0.05). In addition, the incidence of PPI was significantly lower with Evolut R (45, 21.6% vs. 15, 10.9%; p = 0.01). The predictors of the need for PPI were the mean depth of the prosthesis (OR: 1.13, 95% CI: 1.06-1.21; p < 0.0001) and prior right bundle branch block (OR 10.22, 95% CI: 4.62-22.63; p < 0.0001). CONCLUSIONS: The recapturable capability of the Evolut R system allowed for higher and precise valve implantation. This fact had an impact on the reduction in the need for PPI.

BACKGROUND: Vascular complications during transcatheter aortic valve replacement (TAVR) still pose a significant concern regarding procedural safety. Designated closure devices for large-bore vascular access are needed. METHODS: Patients undergoing TAVR were prospectively enrolled into the study. The InSeal vascular closure device (VCD) achieves hemostasis by utilizing a crescent-shaped nitinol scaffold covered by a biodegradable membrane, which is delivered at the arterial puncture site. The coprimary endpoints were predefined as hemostasis within 15 min following vessel access site closure and after activated clotting time falls below 200 s and the rate of related major vascular adverse events in first month. RESULTS: A total of 50 patients were prospectively enrolled into the study, with an average age of 80.8 ± 7.4 years and 62% males. Hemostasis with the Inseal VCD was achieved in 94% of the patients with average time-to-hemostasis of 51 ± 97 s. The rates of in-hospital vascular complications were 12% mostly driven by minor vascular complications (10%). Femoral artery stents were used in three patients due to failed hemostasis. CONCLUSIONS: Initial clinical experience indicates that a novel, nitinol-based, large-bore vascular closure device is safe and effective in achieving hemostasis after TAVR.

BACKGROUND: There is conflicting data as to whether diastolic dysfunction (DD) affects the prognosis of patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). METHODS: Consecutive patients undergoing TAVR underwent assessment of DD with preoperative echocardiography and NT-pro BNP. Long-term survival was ascertained every 6 months by clinic visits or phone. DD was graded according to the new American Society of Echocardiography recommendations. Health status was assessed at baseline and 30 days post-procedure using the KCCQ-12 questionnaire. Long-term survival was displayed using Kaplan-Meier curves according to NT-pro BNP levels and DD grades. RESULTS: We included 222 patients, mean age 78 (±8) years, median STS score 4 (interquartile range = 3-7), median follow-up time 385 days (IQR = 180-640). DD was absent in 25, Grade I in 13, Grade II in 74, Grade III in 24, and indeterminate in 86 patients. Advanced (Grades II-III) DD was associated with higher pre-procedural NT-pro BNP levels (p < .001), worse quality of life (p < .001) but similar surgical risk (p = .43). Advanced and indeterminate DD were associated with increased long-term mortality (25-28% vs. 5%, p = .02) and elevated NT-pro BNP levels (26.4% vs. 9.8%, p = .05). Improvements in quality of life measures were seen in all DD groups (median change in KCCQ score no or Grade I DD:14 [3-21] vs. Grades II-III DD: 15 [16-26; p = .37]). CONCLUSION: Preoperative NT-pro BNP levels and echocardiographic indices of indeterminate or advanced DD are associated with increased long-term mortality after TAVR but similar improvements in quality of life.

AIMS: To evaluate outcomes of transfemoral transcatheter aortic valve implantation (TF-TAVI) using three different new-generation devices. BACKGROUND: Although new generation transcatheter aortic valves (TAVs) have demonstrated to improve procedural outcomes, to date few head-to-head comparisons are available among these devices. METHODS: This is a single center, retrospective study. From September 2014 to February 2018, 389 patients underwent elective TF-TAVI for native, severe aortic stenosis using a new-generation transcatheter aortic valve (TAV) with a preprocedural multi-detector computed tomography assessment. Among these, 346 patients received an Edwards SAPIEN 3 (n = 134), Medtronic Evolut R (n = 111), or Boston ACURATE neo (n = 101) prosthesis. Differences in baseline clinical characteristics between groups were accounted using the propensity score weighting method. RESULTS: The mean age for the entire study cohort was 81.4 ± 5.2 years while the Society of Thoracic Surgery predicted risk of mortality was 4.0 ± 2.5%. After propensity score weighting adjustment, TAVs did not differently impact on 30-day all-cause and cardiovascular mortality. Evolut R device showed an increased risk of permanent pacemaker implantation (PPI) after the procedure (8.3% for SAPIEN 3 vs. 16.7% for Evolut R vs. 2.1% for ACURATE neo, p < .05). At 30 days, patients treated with SAPIEN 3 valve showed a higher mean transvalvular gradient (9.7 ± 7.5 mmHg vs. 6.1 ± 2.4 mmHg vs. 8.4 ± 3.5 mmHg for SAPIEN 3, Evolut R, and ACURATE neo, respectively, p < .01) and a lower rate of more-than-trace paravalvular regurgitation (PVR) (18.8 vs. 47.9 vs. 45.8%, for SAPIEN 3, Evolut R, and ACURATE neo, respectively, p < .01). At 1 year, SAPIEN 3, Evolut R, and ACURATE neo TAVs showed excellent and comparable outcomes with no difference in terms of freedom from major adverse cardiovascular and cerebrovascular event (MACCE) (plog-rank = 0.534). CONCLUSIONS: TAVI using new-generation prostheses was associated with high device success (97.0% vs. 92.8% vs. 95.0% for SAPIEN 3, Evolut R and ACURATE neo, respectively) and low complications rates up to 1 year. Evolut R valve was associated with a higher rate of PPI whereas SAPIEN 3 valve was associated with a higher mean transvalvular gradient and lower rate of more-than-trace PVR. At 1-year, MACCE rates were similar among the three groups.

OBJECTIVES: To evaluate the clinical utility and feasibility of a hybrid technique for obtaining vascular hemostasis by combining a suture- and a collagen-mediated system after transfemoral transcatheter aortic valve implantation (TF TAVI) in a real-world setting. METHODS: In 75 consecutive TF TAVI procedures, we investigated a hybrid closing method to achieve hemostasis at the large bore puncture site using a combination of one presuture closure system (ProGlide) and one collagen-mediated system (Angio-Seal). Vascular complications at puncture site were recorded until discharge. RESULTS: Successful hemostasis by the hybrid technique was achieved in 74 out of 75 patients, and the method was well tolerated by all patients. In 73 patients, (97.3%) neither puncture site related complications nor serious early or late bleedings were observed during a median hospital stay of 2 days postprocedure. CONCLUSION: This single-center registry study indicates that a percutaneous hybrid closure technique is safe and efficacious in closing large bore arteriotomies. It is an easy and reliable technique that may contribute to simplifying TAVI procedures. STUDY REGISTRATION: The data was collected from an internal quality control registry on treatment of patients with valvular heart disease with or without coronary artery disease, No 2014/17280, Oslo University Hospital, Ullevål.
