ABSTRACT

Background: The treatment of choice for patients with severe symptomatic pure native aortic valve regurgitation (PNAVR) is surgical aortic valve replacement (SAVR). However, not all patients are candidates for surgery because of comorbidities or are deemed high risk for surgery. In such cases, transcatheter aortic valve replacement (TAVR) has proved to be better than medical treatment. Case summary: A 78-year-old male with a history of ankylosing spondylitis was admitted with New York Heart Association III heart failure. The echocardiogram showed severe aortic regurgitation and a left ventricular ejection fraction of 52%. Because of high surgical risk and being refractory to medical RX, he was accepted for TAVR. The tomography of anatomical characteristics reported the absence of calcium and dilation of the aortic ring and aortic root. During the TAVR procedure, the patient experienced valve migration, but it was autonomously repositioned in the aortic annulus. As a rescue measure, a second valve was placed. Here, we present a case of valve migration to the left ventricle treated with a valve-in-valve procedure without the need for surgical treatment. Discussion: The absence of annulus calcification in PNAVR increases the risk of post-TAVR paravalvular leak and device embolization. Valve migration generally requires valve recovery and conversion to SAVR.

ABSTRACT

OBJECTIVE: To compare outcomes of patients undergoing valve-in-valve transcatheter aortic valve replacement (ViV TAVR) versus redo surgical aortic valve replacement (SAVR). METHODS: This was a retrospective study using institutional databases of transcatheter (2013-2022) and surgical (2011-2022) aortic valve replacements. Patients who underwent ViV TAVR were compared with patients who underwent redo isolated SAVR. Clinical and echocardiographic outcomes were analyzed. Kaplan-Meier survival estimation and Cox regression were performed. Cumulative incidence functions were generated for heart failure readmissions. RESULTS: A total of 4200 TAVRs and 2306 isolated SAVRs were performed. Of these, there were 198 patients who underwent ViV TAVR and 147 patients who underwent redo SAVR. Operative mortality was 2% in each group, but observed to expected operative mortality in the redo SAVR group was higher than in the ViV TAVR group (1.2 vs 0.32). Those who underwent redo SAVR were more likely to require transfusions and reoperation for bleeding, to have new-onset renal failure requiring dialysis, and to require a permanent pacemaker postoperatively than those in the ViV group. Mean gradient was significantly lower in the redo SAVR group than in the ViV group at 30 days and 1 year. Kaplan-Meier survival estimates at 1 year were comparable, and on multivariable Cox regression, ViV TAVR was not significantly associated with an increased hazard of death compared with redo SAVR (hazard ratio, 1.39; 95% CI, 0.65-2.99; P = .40). Competing-risk cumulative incidence estimates for heart-failure readmissions were higher in the ViV cohort. CONCLUSIONS: ViV TAVR and redo SAVR were associated with comparable mortality. Patients who underwent redo SAVR had lower postoperative mean gradients and greater freedom from heart failure readmissions, but they also had more postoperative complications than the VIV group, despite their lower baseline risk profiles.

ABSTRACT

Severe tricuspid commitment is no longer understood as merely a marker of disease but is now widely thought of as a significant contributor to cardiac morbidity and mortality. However, isolated tricuspid valve surgery remains rare and to this day continues to be associated with the highest surgical risk among all valve procedures and high operative mortality rates, especially in reoperations. Therefore, the development of tricuspid transcatheter procedures is as necessary as it was for the other valves a couple of years ago. Recently, multiple percutaneous therapies have been developed for the management of severe tricuspid disease, initially only repair and more recently replacement, thus creating a new branch for the management of patients who have already undergone surgery and who present with dysfunctional bioprostheses. The purpose of this review and report is to demonstrate current and possible future challenges, and to show that the valve-in-valve procedure of the tricuspid valve is feasible and safe, and now can be performed in all its range, in the smallest to the largest sizes of presentation, without incurring the untoward risks of conventional surgery.

ABSTRACT

Background: Bioprosthetic heart valve has limited durability and lower long-term performance especially in rheumatic heart disease (RHD) patients that are often subject to multiple redo operations. Minimally invasive procedures, such as transcatheter valve-in-valve (ViV) implantation, may offer an attractive alternative, although data is lacking. The aim of this study was to evaluate the baseline characteristics and clinical outcomes in rheumatic vs. non-rheumatic patients undergoing ViV procedures for severe bioprosthetic valve dysfunction. Methods: Single center, prospective study, including consecutive patients undergoing transcatheter ViV implantation in aortic, mitral and tricuspid position, from May 2015 to September 2020. RHD was defined according to clinical history, previous echocardiographic and surgical findings. Results: Among 106 patients included, 69 had rheumatic etiology and 37 were non-rheumatic. Rheumatic patients had higher incidence of female sex (73.9 vs. 43.2%, respectively; p = 0.004), atrial fibrillation (82.6 vs. 45.9%, respectively; p < 0.001), and 2 or more prior surgeries (68.1 vs. 32.4%, respectively; p = 0.001). Although, device success was similar between groups (75.4 vs. 89.2% in rheumatic vs. non-rheumatic, respectively; p = 0.148), there was a trend toward higher 30-day mortality rates in the rheumatic patients (21.7 vs. 5.4%, respectively; p = 0.057). Still, at median follow-up of 20.7 [5.1-30.4] months, cumulative mortality was similar between both groups (p = 0.779). Conclusion: Transcatheter ViV implantation is an acceptable alternative to redo operations in the treatment of patients with RHD and severe bioprosthetic valve dysfunction. Despite similar device success rates, rheumatic patients present higher 30-day mortality rates with good mid-term clinical outcomes. Future studies with a larger number of patients and follow-up are still warranted, to firmly conclude on the role transcatheter ViV procedures in the RHD population.

La disfunción valvular protésica es cada vez más frecuente debido al envejecimiento de la población portadora de bioprótesis y se presenta como un desafío en el momento de su diagnóstico, valoración y tratamiento. Aplicar un enfoque imagenológico multimodal es fundamental para su manejo. Respecto al tratamiento, surge como nueva alternativa un procedimiento mínimamente invasivo de sustitución valvular percutánea, denominado valve in valve, principalmente en pacientes con riesgo quirúrgico elevado. Presentamos uno de los primeros casos locales de implante percutáneo de prótesis mitral transeptal dentro de una bioprótesis mitral quirúrgica disfuncionante.


Prosthetic valve dysfunction is increasingly common due to the aging of the bioprosthesis-bearing population, and it presents a challenge at the time of diagnosis, evaluation, and treatment. A multimodal imaging approach is essential for its management. In relation to treatment, a minimally invasive percutaneous valve replacement procedure called valve in valve arises as a new alternative, mainly in patients with high surgical risk. We present one of first local cases of percutaneous implantation of a transseptal mitral prosthesis within a dysfunctional surgical mitral bioprosthesis.

ABSTRACT

OBJECTIVES: Concomitant valvular heart valve disease is a frequent finding, with higher morbidity and mortality among patients undergoing redo surgical procedures. Our goal was to report our initial experience with combined transcatheter Inovare bioprosthesis implants for severe valve dysfunction. METHODS: Among 300 transcatheter procedures, a total of 6 patients had concurrent simultaneous transcatheter bioprosthesis implants for severe mitral bioprosthesis failure (valve-in-valve), with a second valve procedure that included native aortic (n = 2) or degenerated bioprostheses in the aortic position (n = 4). During the procedures, all patients were treated with a balloon-expandable Inovare transcatheter valve, using the transapical approach. RESULTS: Patients were highly symptomatic [New York Heart Association (NYHA) functional class IV: 100%], with a mean age of 62 ± 5 years, yielding a mean European System for Cardiac Operative Risk II (EuroSCORE II) of 24.0 ± 10.1%. There was a mean of 1.6 ± 0.4 prior valve operations/patient, with a median time from prior mitral bioprosthesis surgery of 13.0 (9.2-20.0) years. Device success was 100% according to the Mitral Valve Academic Research Consortium and the Valve Academic Research Consortium-2 criteria. During the hospital stay, only 1 patient required dialysis, and the median intensive care unit and hospital lengths of stay were 5.0 (3.2-6.7) days and 16.0 (12.2-21.2) days, respectively. No deaths occurred at 30 days; at a median follow-up of 287 (194-437) days, 1 patient died of a non-cardiac cause and the rest of patients were in NYHA functional class I or II, with normofunctioning bioprostheses. CONCLUSIONS: Transcatheter double valve interventions using the Inovare bioprosthesis in this initial series were shown to be a reasonable alternative to redo surgical operations. The short- and mid-term clinical and echocardiographic outcomes demonstrate promising results, although future studies with a larger number of patients and longer follow-up are warranted.

ABSTRACT

OBJECTIVES: Our goal was to analyse the initial results of the first 50 transapical transcatheter mitral valve-in-valve procedures performed in a single Latin American centre. METHODS: A prospective, single centre, database analysis was conducted to evaluate immediate, 30-day and 1-year postoperative results of 50 consecutive patients who had a transcatheter mitral valve-in-valve procedure from May 2015 to June 2018. All patients were operated on in a hybrid operating room and received a balloon-expandable valve via the transapical approach. Preoperative and postoperative characteristics were analysed and compared between the first 25 and the second 25 patients to evaluate the impact of the learning curve. Twenty patients had a follow-up examination at 1 year. RESULTS: There was a 98% device success rate. The patients had a mean age of 64.8 years; 72% were women; 80% were in New York Heart Association functional class ≥III preoperatively; and 36% of the procedures were urgent. The mean Society of Thoracic Surgeons scores and EuroSCORE II were 8.3% and 12.4%, respectively. Patients had a median of 2 previous operations; valve durability was 12.1 years; and 64% mitral valve disease of rheumatic fever aetiology. Echocardiography showed decreases in the maximum and mean mitral gradients from 23.5 to 14.6 and 11.5 to 6.4 mmHg postoperatively; the overall mean hospitalization period was 15 days. The overall mortality rate at 30 days was 14%, with 1 intraprocedural death. Further subanalyses between the first and the second half of the cases showed a drop in the mortality rate from 20% to 8% (P < 0.01). CONCLUSION: The transcatheter mitral valve-in-valve procedure was shown to be a safe and effective procedure to treat bioprosthetic dysfunction, with potential benefits in patients with rheumatic disease.

ABSTRACT

Coronary obstruction is a rare but life-threatening complication in patients undergoing transcatheter aortic valve replacement (TAVR). Aortic valve-in-valve (VIV) procedures to treat failed surgical bioprosthesis is associated with ~6-fold higher risk for coronary obstruction in certain situations. The primary mechanism consists in the occlusion of the coronary ostium by the dislodged leaflet from the bioprosthesis after deployment of the transcatheter heart valve (THV), which most commonly occurs during the index procedure, but in up to 1/3 of cases a delayed presentation ensues. The clinical presentation consists of severe hypotension and ECG changes in most of the patients, with very high mortality rates. Therefore, pre-procedural multi-slice computed tomography is crucial for identifying high-risk features, such as low coronary heights, shallow sinuses of Valsalva, and short virtual THV to coronary ostial distance (VTC). Also, some models of surgical bioprosthesis present an increased risk for this dreadful complication. Preemptive protective strategies with coronary wiring, with or without placement of an undeployed stent, could mitigate the risks associated with this complication in high-risk patients, even though studies are lacking. This review aims to take a clinical perspective on the challenges in avoiding this complication during VIV procedures.

ABSTRACT

La disfunción de las bioprótesis quirúrgicas frecuentemente ocurre en pacientes añosos, con severas comorbilidades, lo que implica un riesgo elevado frente a una nueva cirugía valvular. El implante de válvulas transcatéter dentro de bioprótesis disfuncionantes o procedimiento valve in valve (VIV), ha sido desarrollado como una nueva alternativa terapéutica para este tipo de situación. Los procedimientos VIV deben ser considerados para pacientes con disfunción protésica severa sintomática con alto riesgo quirúrgico, luego de un exhaustivo análisis individualizado por un grupo de expertos o heart team. La selección y evaluación previa de los pacientes son fundamentales para el éxito del procedimiento. La evidencia respalda más fuertemente este tipo de intervención en posición aórtica que en posición mitral. En esta revisión analizamos brevemente las indicaciones, la evaluación previa de los pacientes, los aspectos relevantes del procedimiento y sus complicaciones eventuales, con especial énfasis en el procedimiento VIV mitral, que ha sido motivo de dos recientes reportes de casos en esta revista.

Bioprosthetic surgical valve dysfunction occurs frequently in elderly patients with severe comorbidities, which implies a high surgical risk in case of redo valve surgery. Transcatheter valve implantation within a surgical bioprosthesis, so-called valve in valve procedure (VIV), has been developed as new treatment option for this situation. VIV procedures should be considered in patients with severely symptomatic prosthetic valve dysfunction with high surgical risk, after careful heart team evaluation. Patient selection and pre-procedural evaluation are mainstay for procedural success. Current evidence has stronger support for VIV procedure in aortic than in mitral position. In this review, we briefly analyze VIV procedure indications, patient evaluation, as well as relevant aspects of the procedure itself and its most frequent complications. Special emphasis will be given for VIV in mitral position which has been the focus of two recent case reports in this journal.

ABSTRACT

Transcatheter aortic valve replacement (TAVR) has emerged as an accepted indication for non-operable patients with severe symptomatic native aortic valve stenosis (AS) and as a reasonable alternative for high-risk surgical AS patients. Nonetheless, the safety and efficacy of performing TAVR in several other potential indications are yet unclear. In the present manuscript the authors review the current evidence supporting TAVR for other potential indications than the typical high-risk/non-operable AS patients, providing updated results of the main clinical trials and registries exploring these particular indications. Finally, the authors provide practical recommendations for TAVR in each of these conditions.
