ABSTRACT
Objective:
To investigate the feasibility and efficacy of percutaneous closure of paravalvuar leak (PVL) in patients after heart valve replacement surgery using Amplatzer vascular plug â ¢ (AVP â ¢).Methods:
In this retrospective study, consecutive PVL patients after heart valve replacement surgery receiving percutaneous closure with AVP â ¢ in Beijing Anzhen hospital between March 2017 and October 2018 (n=21) were enrolled.The preoperative and intraoperative data and short-and mid-term outcome results were analyzed.Results:
Theage of patients in this cohort was (54.9±11.7) years, and there were 12 (57.1%) male patients. There were 8 patients (38.1%) post mitral valve replacement, 4 patients (19.0%) post aortic valve replacement and 9 patients (42.9%) post double valves replacements.There were 14 cases (66.7%) of mitral valve PVL,6 cases (28.6%) of aortic valve PVL, and 1 case (4.8%) of double valves PVL.Successful device deployment was accomplished in 18 defects from 17 PVL patients. Technical successful rate of mitral valve PVL closure and aortic valve PVL closure was 12/15 and 6/7,respectively. One patient received surgical repair due to procedure-induced femoral pseudoaneurysm.There were 17 cases of severe PVL and 1 case of moderate PVL before procedure, and there were 2 cases of moderate PVL, 6 cases mild PVL, and PVL disappeared in 10 cases after procedure (P<0.01 vs. pre-procedure). The follow-up time was (8.3±4.7) months. There were 10 cases (58.8%) of New York Heart Association (NYHA) function grade â ¢ and 7 cases (41.2%) of NYHA function grade â £ before procedure, and there were 12 cases of NYHA function grade â (70.6%) and 5 cases (29.4%) of NYHA function grade â ¡ post procedure (P<0.01). Post procedure, there was no displacement of the occluder and heart valve movement was not affected,and there was no new hemolysis or hemolysis worsening.Conclusion:
Percutaneous closure of PVL in patients after heart valve replacement surgery with AVP â ¢ is feasible, and associated with favorable short-and mid-term clinical outcomes.Key words
