Project description:Transcatheter aortic valve implantation (TAVI) within failed bioprosthetic surgical aortic valves (valve-in-valve TAVI) has become an established procedure, currently approved for patients deemed at high risk for repeat aortic valve intervention. Although less invasive than surgical reoperation, challenges of valve-in-valve treatment include higher rates of malposition, prosthesis-patient mismatch and coronary obstruction. Thus, optimal patient selection and preprocedural planning is of the utmost importance to minimise the risk of these complications. In this review article we provide a fully illustrated overview of the most significant periprocedural operative considerations for valve-in-valve TAVI.

Project description:BackgroundAortic regurgitation (AR) is a condition associated with significant morbidity and mortality, particularly in severe cases. The J-Valve system, next-generation transcatheter heart valve, may overcome the procedural challenges associated with treating pure AR. This study reported the outcome of use of the J-Valve for treatment of AR.MethodsThis study observed 47 patients undergoing transcatheter aortic valve implantation (TAVI) with the J-Valve system. Diagnostic evaluation included transthoracic echocardiography and multislice computed tomography to assess AR severity and anatomic characteristics essential for TAVI. Follow-up evaluations were conducted at various intervals postoperation to evaluate outcomes.ResultsThe patients had a mean age of 73.0 ± 9.0 years and a median ejection fraction of 58.0% (interquartile range, 45.0%-64.0%). The median European System for Cardiac Operative Risk Evaluation (EuroSCORE II) was 3.0% (interquartile range, 2.0%-6.7%). The procedural success rate was 100%, with no need for a second valve implantation or conversion to sternotomy. Short-term outcomes showed significant improvements in the New York Heart Association functional classification (P < 0.001), the left ventricular ejection fraction (P = 0.009), and the left ventricular end-diastolic diameter (P < 0.001). A singular case of valve migration and severe perivalvular leakage due to Behçet's disease prompted a revised approach incorporating immunomodulation therapy.ConclusionsTAVI with the J-Valve system presents a viable alternative for managing severe AR, demonstrating high procedural success and substantial clinical improvement. However, the case of valve migration due to Behçet's disease highlights the need for careful preoperative screening and consideration of autoimmune disorders in differential diagnoses.

Project description:BackgroundValve-in-valve transcatheter aortic valve implantation (TAVI) has emerged as a competent alternative for the treatment of degenerated bioprosthetic valves after surgical aortic valve replacement, or during TAVI procedure as a bailout option. Herein, we report a rare case of a self-expandable Medtronic Evolut R valve into a failing Medtronic CoreValve, with the use of modern pre-TAVI imaging screening, suggesting the proper procedural design steps for so complicated implantations.Case summaryA frail 78-year-old woman with a degenerated Medtronic Core Valve 26 mm bioprosthesis, implanted in 2011 due to severe aortic stenosis, was referred to our hospital due to worsening dyspnoea New York Heart Association III. The screening echocardiography documented severe aortic stenosis, while the classical risk scores were in favour of repeated TAVI (EuroSCORE II 5.67%). Computed tomography measurements and three-dimensional (3D) printing model were of great help for the proper valve selection (Medtronic Evolut R 26 mm), while the use of cerebral protection device (Claret Sentinel) was considered as a necessary part of the procedure. The simultaneous use of fluoroscopy and transoesophageal echocardiogram led to optimal haemodynamic result, confirmed by the discharge echocardiogram, with a significant clinical improvement during the first month follow-up.DiscussionThe main periprocedural concerns remain valve malpositioning, coronary artery obstruction, and high remaining transvalvular gradients. The multimodality pre-TAVI imaging screening may be helpful for precise procedural design. Despite the limited use of 3D models, it is necessary to adopt such tissue-mimicking phantoms to increase the possibility of optimal procedural result.

Project description:Off-pump transapical aortic valve implantation (TA-TAVI) through mini-thoracotomy was first performed in Vancouver, Canada in October 2005. The objective of this manuscript is to describe the Vancouver experience with 178 TA-TAVI cases in symptomatic severe aortic stenosis (AS) since 2005.Baseline characteristics and in-hospital outcomes were calculated for the overall cohort. To compare pre-procedure and post-procedure echocardiographic measurements, one way analysis of variance was utilized, followed by Tukey's HSD. In-hospital outcomes were compared between early and late cohorts using Z-test and chi-squared test as appropriate. Kaplan-Meier analysis was used to generate 3-year survival curves. The Log-rank test was used to compare survival between low-risk and high-risk groups, based on STS score.Between October 2005-March 2012, TA-TAVI was performed in 178 patients. Mean age was 80.5±8.6 years. Congestive heart failure and renal failure were more common in the late cohort, while previous myocardial infarction was more common in the early cohort (P<0.05). Eleven patients (6.2%) had significant intra-operative complications, including death (1.7%), conversion to CPB (3.9%), and valve embolization (1.1%). In-hospital survival was 87.9%. Mean length of hospital stay was 12.2±17.1 days. In-hospital incidence of stroke was 3.4%. Bleeding (20.2% vs. 4.7%) and vascular (14.6% vs. 3.5%) complications were more common in the early cohort. Echocardiography demonstrated a significant increase in aortic valve area and decrease in mean transvalvular gradient post-procedure. These improvements were maintained throughout the 3-year follow-up period. Overall survival was 72.1% at 6 months, 67.7% at 12 months, 55.5% at 24 months, and 47.3% at 36 months. Repeated Kaplan-Meier analysis for the 2 groups stratified by STS score, demonstrated improved survival in the low-risk group (Log-rank P=0.039).Among patients with symptomatic severe AS at high risk for conventional AVR, TA-TAVI is a reasonable therapeutic option with acceptable risk. Long-term survival appears to be superior in lower-risk patients.

Project description:A 67-year-old male patient who had undergone double valve replacement 11 years before presented with severe dyspnea to our department. The bioprosthetic aortic and mitral valves have failed. Because of the high risk of redo surgery. We perform a simultaneous transapical transcatheter valve-in-valve replacement of degenerated aortic and mitral bioprosthetic valves with limited radiopaque landmarks using the second-generation self-expanding J-valve. The post-operative course was stable and the patient was discharged on post-operative day eight.

Project description:Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients with severe aortic valve stenosis. Given the burden of valvular heart disease in the general population and the increasing numbers of patients who have had previous valve operations, we are now seeing a growing number of high-risk patients presenting with prosthetic valve stenosis, who are not potential surgical candidates. For this high-risk subset transcatheter valve delivery may be the only option. Here, we present an inoperable patient with severe, prosthetic valve aortic and mitral stenosis who was successfully treated with a trans catheter based approach, with a valve-in-valve implantation procedure of both aortic and mitral valves.

Project description:Background: Valve-in-Valve transcatheter aortic valve implantation (ViV-TAVI) is a growing alternative for redo-surgery in patients with degenerated surgical valves. To our knowledge, data are lacking on the determinants on ViV-TAVI procedural success in patients with degenerated surgical valves. Methods: All consecutive patients undergoing ViV-TAVI for degenerated surgical valves at the Cleveland Clinic were analyzed. Data were extracted from our patient registry on baseline patient characteristics, echocardiographic parameters, and procedural details. To identify possible predictors of ViV-TAVI procedural success, we employed a multivariate logistic regression model. Results: A total of 186 patients who underwent ViV-TAVI were analyzed, with procedural success (VARC-2 device success and absence of periprocedural MACCE) reported in 165 (88.7%) patients. Patients with successful ViV-TAVI were significantly younger and had more frequent utilization of the transfemoral access than those with failed procedure. Other baseline and procedural characteristics were comparable between both groups. In terms of echocardiographic parameters, the procedural success group had a significantly lower AV peak pressure gradient (62.1 ± 24.7 vs. 74.1 ± 34.6 mmHg; p = 0.04) and lower incidence of moderate-to-severe aortic regurgitation [AR] (30.4 vs. 55%; p = 0.04). However, no significant differences between both groups were noted in terms of AV mean pressure gradient and left ventricular measurements. In multivariate analysis, lower AV peak pressure gradient (OR = 0.97, 95% CI: 0.95-0.99) and absence of moderate-to-severe AR (OR = 0.65, 95% CI: 0.44-0.95) at baseline emerged as independent predictors of ViV-TAVI procedural success. Conclusion: Valve-in-Valve TAVI for degenerated surgical valves is a feasible approach with high success rates, especially in those with lower AV peak pressure gradient and absence of moderate-to-severe AR. Studies with larger sample size and longer follow-up are required to further characterize the predictors of ViV-TAVI success and other clinical outcomes.

Project description:It has been reported that PECS II block can alleviate postoperative pain following transapical transcatheter aortic valve implantation (TA-TAVI). However, the effectiveness of continuous PECS II block with catheterization has not yet been reported on the postoperative pain in patients undergoing TA-TAVI. We experienced two cases of TA-TAVI who received PECS II block with catheterization to manage postoperative pain. In the first case, a bolus injection for intraoperative pain and subsequent catheterization were performed before the implantation. However, the patient developed severe pain postoperatively in spite of the continuous block due to displacement of the catheter. In the second case, a bolus injection and the catheterization for the continuous block were performed before and after the implantation, respectively, which provided high-quality pain control. Continuous PECS II block may be useful to control perioperative pain associated with TA-TAVI. The insertion of the catheter after the implantation could be useful to avoid its displacement during the surgery.
