Functional assessment of mitral regurgitation by transthoracic echocardiography using standardized imaging planes diagnostic accuracy and outcome implications.

摘要: OBJECTIVES We sought to assess the value of transthoracic echocardiography (TTE) using standardized imaging planes for functional analysis mitral regurgitation (MR) as well postoperative outcome implications. BACKGROUND The feasibility valve repair is based on assessment MR, mainly by transesophageal (TEE). Considering recent advances in TTE imaging, incremental TEE this setting needs be re-examined. METHODS Consecutive patients (n = 279; 181 men; median age 68 years [quartiles, 61 74]) who underwent surgery MR were enrolled prospectively two tertiary care centers. accuracy (harmonic imaging) versus was evaluated against surgical findings. RESULTS Valve 237 patients, 85%) or replacement 42) predicted accurately 97% cases; added significant information only patients. In subgroup degenerative 190), agreement with findings localization prolapsed segments 91% (kappa, 0.81) and 93% 0.85) without (p 0.40). Patients single prolapse middle posterior scallop (P2) had a better compared non-P2 lesions 0.008). Furthermore, an independent predictor long-term mortality (odds ratio 5.7, 95% confidence interval 1.97 16.4, p 0.001). CONCLUSIONS experienced hands, can predict repairability has strong influence outcome. Thus, most cases preoperative not mandatory, provided intraoperative performed.
