Cardio-mechanical parameters were evaluated non-invasively using a modified single-beat method. After the exclusion of nine patients requiring intravenous catecholamine infusion, the study cohort comprised 49 consecutive patients (25 men; mean age: 81 ± 9 years) with successful mitral TEER. ARD in LV function was defined as a decrease in LV ejection fraction (LVEF) of ≥5 points following the procedure by TTE, which was reported in 18 patients.

A study by Zach et al. (2024) demonstrated the feasibility of this technique in 64% of patients, offering a viable alternative when 3D echocardiography is unavailable or non-diagnostic. The study found no significant correlation between lead position and TR severity, suggesting that other factors may contribute to TR development. While the subcostal en face view holds significant promise, limitations such as poor image quality in patients with obesity, abdominal pathologies, or multiple leads, as well as the need for experience to maximize success rates, must be addressed. Future prospective studies are needed to validate the clinical benefits of the subcostal en face view during CIED implantation, including its impact on procedural duration and TR prevention.
