OBJECTIVES:Transfemoral (TF) access for transcatheter aortic valve replacement (TAVR) may be challenging in patients with peripheral arterial disease (PAD). Alternative access through intra- and extrathoracic approaches can be performed. Recently, a facilitated TF access strategy, which involves the use of intravascular lithotripsy to optimize the iliofemoral arteries prior to TAVR, has been utilized. The aim of this study was to evaluate early outcomes of facilitated TF access compared to alternative access in patients with severe PAD. METHODS:Patients with severe PAD who underwent TAVR from 2021 to 2023 were included in the study and were divided into 2 groups: facilitated and alternative access. The primary endpoint was a composite of mortality, stroke, and vascular complications. Mortality was evaluated in-hospital and at 1-month follow-up. RESULTS:Of 150 TAVR patients with severe PAD, 24 underwent facilitated access. Baseline characteristics including age, Society of Thoracic Surgeons score, and mean gradients were similar between the 2 groups. The most common alternative access was transsubclavian, followed by transcarotid. Primary outcomes were numerically higher in the alternative access group (14% vs 8%); however, this did not reach statistical significance (P = .49). General anesthesia use and postoperative length of stay were higher in the alternative access group. Postoperative and 1-month mortalities were similar between the 2 groups. CONCLUSIONS:Although the primary endpoint did not reach statistical significance, the numerical trend toward better outcomes in the facilitated TAVR group indicates a potential advantage. Large-scale prospective studies are required to determine the appropriate access strategy for TAVR in patients with severe PAD.
A 79-year-old man with a failed 25-mm CE Magna Ease 3300 surgical prosthesis and of high re-operative surgical risk (STS 8%) presented with dyspnea, NYHA III. Cardiac computed tomography angiography revealed anatomy that was high risk for coronary occlusion with a short right coronary artery height of 6 mm and a valve-to-coronary distance of 2 mm.
BackgroundHemostasis for transfemoral transcatheter aortic valve replacement (TAVR) is typically achieved using a suture-mediated vascular closure device (VCD) prior to large bore sheath insertion (preclosure technique). Recently, the addition of a hybrid closure technique using a preclose technique with the addition of a collagen-plug VCD after sheath removal in cases of failed hemostasis has been utilized.MethodsData were collected from the Northwell TAVR registry, including 3 high volume TAVR centers. We evaluated a preclose strategy with suture-mediated vascular closure alone (“legacy strategy”) and standard bailout techniques versus a contemporary hybrid strategy of suture-mediated closure with collagen-mediated closure bailout. The primary end point was major or minor vascular complications as defined by the VARC3 criteria.ResultsA total of 1327 patients were included, of which 791 patients underwent TAVR with suture-mediated closure alone and 536 with contemporary strategy. The primary end point (major or minor vascular complication) was lower in the contemporary strategy (5.44% vs 1.31%; P < .001). Both minor (3.92% vs 1.12%; P = .002) and major (1.14% vs 0.19%; P = .0196) vascular complications were reduced and the total length of stay was less in the contemporary strategy (median of 3 days vs 2 days; P < .0001). Using multivariate analysis, we observed that vascular management strategy significantly improved the composite primary outcome when adjusted for sheath size, peripheral artery disease, carotid disease, and site of procedure. In the contemporary group, bailout collagen-plug VCD with an Angioseal (Abbott Vascular Devices) was used in 68 patients (12.69%) and bailout MANTA (Teleflex) was required in 4 patients (0.75%). There were no major or minor vascular complications among the patients who received bailout collagen-plug VCD.ConclusionsA contemporary hybrid strategy of suture-mediated closure with collagen-mediated closure bailout reduces the risk of vascular complications among patients undergoing transfemoral TAVR.
BackgroundMitral annular calcification (MAC) has been an exclusion for many of the earlier pivotal trials that were instrumental in gaining device approval and indications for mitral transcatheter edge-to-edge repair (M-TEER).AimsTo evaluate the impact of MAC on the procedural durability and success of newer generation MitraClip (R) systems (G3 and G4 systems).MethodsData were collected from Northwell TEER registry. Patients that underwent M-TEER with third or fourth generation MitraClip device were included. Patients were divided into -MAC (none-mild) and +MAC (moderate-severe) groups. Procedural success was defined as <= grade 2 + mitral regurgitation (MR) postprocedure, and durability was defined as <= grade 2 + MR retention at 1 month and 1 year. Univariate analysis compared outcomes between groups.ResultsOf 260 M-TEER patients, 160 were -MAC and 100 were +MAC. Procedural success was comparable; however, there were three patients who required conversion to cardiac surgery during the index hospitalization in the +MAC group versus none in the -MAC group (though this was not statistically significant). At 1-month follow-up, there were no significant differences in MR severity. At 1-year follow-up, +MAC had higher moderate-severe MR (22.1% vs. 7.5%; p = 0.002) and higher mean transmitral gradients (5.3 vs. 4.0 mmHg; p = 0.001) with no differences in mortality, New York Heart Association functional class or ejection fraction.ConclusionIn selective patients with high burden of MAC, contemporary M-TEER is safe, and procedural success is similar to patients with none-mild MAC. However, a loss of procedural durability was seen in +MAC group at 1-year follow-up. Further studies with longer follow-ups are required to assess newer mTEER devices and their potential clinical implications in patients with a high burden of MAC.
