Abstract
BACKGROUND Previous reports suggest septal hypertrophy with an interventricular septum depth (IVSD) ≥ 14 mm may adversely affect outcomes after transcatheter aortic valve implantation (TAVI) due to suboptimal valve placement, valve migration, or residual increased LVOT pressure gradients. AIMS This analysis investigates the impact of interventricular septal hypertrophy on acute outcomes after TAVI. METHODS Between 2009 and 2021, 1033 consecutive patients (55.8% male, 80.5 ± 6.7 years, EuroSCORE II 6.3 ± 6.5%) with documented IVSD underwent TAVI at our center and were included for analysis. Baseline, periprocedural, and 30-day outcome parameters of patients with normal IVSD (< 14 mm; group 1) and increased IVSD (≥ 14 mm; group 2) were compared. Data were retrospectively analyzed according to updated Valve Academic Research Consortium-3 (VARC-3) definitions. Comparison of outcome parameters was adjusted for baseline differences between groups using logistic and linear regression analyses. RESULTS Of 1033 patients, 585 and 448 patients were allocated to groups 1 and 2, respectively. There was no significant difference between groups regarding transfemoral access rate (82.6% (n = 478) vs. 86.0% (n = 381), p = 0.157). Postprocedural mean transvalvular pressure gradient was significantly increased in group 2 (group 1, 7.8 ± 4.1 mmHg, vs. group 2, 8.9 ± 4.9 mmHg, p = 0.046). Despite this finding, there was no significant difference between groups regarding the rates of VARC-3 adjudicated composite endpoint device success (90.0% (n = 522) vs. 87.6% (n = 388), p = 0.538) or technical success (92.6% (n = 542) vs. 92.6% (n = 415), p = 0.639). Moreover, the groups showed no significant differences regarding the rates of paravalvular leakage ≥ moderate (3.1% (n = 14) vs. 2.6% (n = 9), p = 0.993), postprocedural permanent pacemaker implantation (13.4% (n = 77) vs. 13.8% (n = 61), p = 0.778), or 30-day mortality (5.1% (n = 30) vs. 4.5% (n = 20), p = 0.758). CONCLUSION Although transvalvular mean pressure gradients were significantly higher in patients with increased IVSD after TAVI, acute outcomes were comparable between groups suggesting no early impact of adverse hemodynamics due to elevated IVSD. However, how these differences in hemodynamic findings may affect mid- and long-term outcomes, especially in terms of valve durability, needs to be evaluated in further investigations.

Acute Hemodynamic Compromise After Transcatheter Aortic Valve Replacement Due to Dynamic Left Ventricle Obstruction: A Systematic Review. Am J Cardiol 2024; 214:125-135. [PMID: 38103763 DOI: 10.1016/j.amjcard.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/08/2023] [Accepted: 12/09/2023] [Indexed: 12/19/2023]
Abstract
Acute hemodynamic compromise after transcatheter aortic valve replacement (TAVR) because of dynamic left ventricle (LV) obstruction (LVO), also known as suicide LV, is an infrequent but severe complication of TAVR that is poorly defined in previous studies. Understanding this complication is essential for its prompt diagnosis and optimal treatment. We conducted a systematic literature review using PubMed, Embase, Web of Science, and Medline databases for studies describing acute hemodynamic compromise after TAVR because of dynamic LVO or suicide LV. Each study was reviewed by 2 authors individually for eligibility, and a third author resolved disagreements. From a total of 506 studies, 25 publications were considered for the final analysis. The majority of patients with this condition were women demonstrating a hypertrophic septum, a small ventricle, and hyperdynamic contractility on pre-TAVR echocardiographic assessment. An intraventricular gradient before TAVR was found in half of the cases. Acute hemodynamic compromise after TAVR because of dynamic LVO manifested mainly as significant hypotension and occurred most often immediately after valve deployment. The LV outflow tract was the most common site of obstruction. Advanced therapies were required in nearly 65% of the cases. In conclusion, acute hemodynamic compromise after TAVR because of dynamic LVO occurred almost invariably in women. Echocardiography before TAVR may offer essential information to anticipate this complication. LV outflow tract obstruction appears to carry the highest risk of developing this phenomenon. Advanced therapies should be promptly considered as a bailout strategy in patients with hemodynamic collapse refractory to medical therapy.
