Incidental detection of malignancy during preprocedural workup for transcatheter aortic valve implantation: A longitudinal cohort study

Clinical Outcomes and Prognostic Implications of TAVR in Patients With Active Cancer: A Meta-Analysis

BACKGROUND

Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) for high-risk patients with severe aortic stenosis (AS). However, the clinical outcomes and prognostic implications of TAVR in patients with active cancer remain uncertain. This meta-analysis evaluates procedural success, complications, and survival outcomes of TAVR in patients with and without active cancer.

METHODS

A comprehensive literature search was conducted across PubMed, Scopus, and Web of Science databases. Statistical analysis was performed using a random-effects model. Statistical analyses were conducted using STATA version 18.0.

RESULTS

The results of the meta-analysis showed no significant difference in in-hospital mortality between cancer and non-cancer patients (OR = 1.17; 95% CI: 0.83, 1.65; p = 0.27). Similarly, 30-day mortality did not differ between the two groups (OR = 0.93; 95% CI: 0.72, 1.19; p = 0.49). However, 1-year mortality was significantly higher in cancer patients (OR = 1.93; 95% CI: 1.45, 2.56; p < 0.01). Two-year mortality was also higher in cancer patients (OR = 2.65; 95% CI: 1.79, 3.93; p < 0.01). No significant differences were observed in major bleeding, acute kidney injury, stroke, or permanent pacemaker implantation between the groups.

CONCLUSION

While TAVR offers comparable in-hospital and short-term survival outcomes for cancer and non-cancer patients, long-term mortality is significantly higher in those with active cancer. These findings suggest that TAVR is a viable option for cancer patients with severe AS but requires careful long-term prognostic considerations. Further studies are needed to optimize management strategies for this complex population.

Myocardial analysis from routine 4D cardiac-CT to predict reverse remodeling and clinical outcomes after transcatheter aortic valve implantation

PURPOSE

Our study aimed to determine whether 4D cardiac computed tomography (4DCCT) based quantitative myocardial analysis may improve risk stratification and can predict reverse remodeling (RRM) and mortality after transcatheter aortic valve implantation (TAVI).

METHODS

Consecutive patients undergoing clinically indicated 4DCCT prior to TAVI were prospectively enrolled. 4DCCT-derived left- (LV) and right ventricular (RV), and left atrial (LA) dimensions, mass, ejection fraction (EF) and myocardial strain were evaluated to predict RRM and survival. RRM was defined by either relative increase in LVEF by 5% or relative decline in LV end diastolic diameter (LVEDD) by 5% assessed by transthoracic echocardiography prior TAVI, at discharge, and at 12-month follow-up compared to baseline prior to TAVI.

RESULTS

Among 608 patients included in this study (55 % males, age 81 ± 6.6 years), RRM was observed in 279 (54 %) of 519 patients at discharge and in 218 (48 %) of 453 patients at 12-month echocardiography. While no CCT based measurements predicted RRM at discharge, CCT based LV mass index and LVEF independently predicted RRM at 12-month (ORadj = 1.012; 95 %CI:1.001-1.024; p = 0.046 and ORadj = 0.969; 95 %CI:0.943-0.996; p = 0.024, respectively). The most pronounced changes in LVEF and LVEDD were observed in patients with impaired LV function at baseline. In multivariable analysis age (HRadj = 1.037; 95 %CI:1.005-1.070; p = 0.022) and CCT-based LVEF (HRadj = 0.972; 95 %CI:0.945-0.999; p = 0.048) and LAEF (HRadj = 0.982; 95 %CI:0.968-0.996; p = 0.011) independently predicted survival.

CONCLUSION

Comprehensive myocardial functional information derived from routine 4DCCT in patients with severe aortic stenosis undergoing TAVI could predict reverse remodeling and clinical outcomes at 12-month following TAVI.
