ABSTRACT
BACKGROUND:
In patients with symptomatic mitral PVL, successful transcatheter reduction of the PVL to less than mild is associated with significant improvement in short- and midterm survival.OBJECTIVES:
In this study, we present our single-centre, same operators' experience on percutaneous paravalvular leak closure with techniques and outcomes.METHODS:
In this retrospective observational designed study, we retrieved hospital records of patients with a surgical history of mechanical or biological prosthetic valve replacement and who subsequently underwent transcatheter mitral paravalvular leak closure (TMPLC). All procedures were performed by the same operators.RESULTS:
A total of 45 patients with 58 PVDs underwent TMPLC using 60 devices. All patients had moderate or severe mitral paravalvular regurgitation associated with symptomatic HF (15.6%), clinically significant haemolytic anaemia (57.8%) or both (26.7%). The technical success rate was 91.4%, with 53 defects successfully occluded. The clinical success rate was 75.6%. Among the clinical success parameters, the preprocedural median ejection fraction increased from 45% (35-55) to 50% (40-55) (p = .04). Mitral gradients decreased from max/mean 18/8 mmHg to max/mean 16/7 mmHg; p = .02). Haemoglobin levels increased from 9.9 (8.5-11.1) to 11.1 (3-13); p = .003. LDH levels decreased from 875 (556-1125) to 435 (314-579); p <.001. All-cause 30-day and in-hospital mortality rates were the same at 8.9%.CONCLUSION:
This single-centre study with a limited number of patients confirmed that TMPLC is a safe and effective procedure to improve symptoms and severity of PVL.
