ABSTRACT
AIMS:
Percutaneous mitral annuloplasty (PMA) represents a new treatment option for secondary mitral regurgitation (SMR) being associated with higher morbidity and mortality. The present study was aimed to evaluate whether or not acute effects on SMR severity can quantitatively be assessed after PMA. METHODS ANDRESULTS:
PMA was performed in 30 patients (mean age 76 ± 9; 37% males) with moderate (n = 14) or severe (n = 16) SMR. Vena contracta (VC), left ventricular (LV) velocity-time-integral ratio (VTIMV/LVOT ), effective regurgitant orifice area (EROA) by two-dimensional proximal isovelocity surface area (PISA), regurgitant volume (RVolPISA ) and regurgitant fraction (RFPISA ) by PISA, RVolvolume and RFvolume by LV volume analyses, and parameters describing LV morphology, function, and cardiac performance were assessed by transthoracic echocardiography prior to and after PMA. According to RFPISA /RFvolume , 14 patients showed mild, 15 moderate, and 1 severe SMR after PMA. Mean RF, RVol, EROA, VC, and VTIMV/LVOT were lower directly after PMA (RFPISA 49% ± 11 vs. 34% ± 13, P < 0.001; RFvolume 46% ± 10 vs. 34% ± 13, P < 0.001; RVolPISA 33 mL ± 13 vs. 25 mL ± 12, P < 0.001; RVolvolume 28 mL ± 17 vs. 20 mL ± 14, P < 0.05; EROAPISA 0.24 cm2 ± 0.1 vs. 0.19 cm2 ± 0.1, P < 0.05; VC 5.2 ± 0.1 vs. 4.1 ± 0.2, P < 0.001; VTIMV/LVOT 1.9 ± 0.4 vs. 1.6 ± 0.5, P < 0.05). Parameters of LV morphology, function, and cardiac performance did not change directly after PMA.CONCLUSIONS:
PMA leads to a reduction of MR severity in >80% of SMR patients. Acute effects of PMA can quantitatively be assessed by transthoracic echocardiography.Palavras-chave
