Abstract Background This study was conducted to assess the accuracy of harmonic imaging 2D-transthoracic echocardiography (2D-TTE) segmental analysis compared to surgical findings, in degenerative mitral regurgitation (MR).Methods Seventy-seven consecutive patients with severe degenerative MR were prospectively enrolled.Preoperative 2D-TTE with precise localization of prolapsing or flailing scallops/segments was performed.All patients underwent mitral valve surgical repair.Surgical reports (SR), including valve description, were Rear Camera Cable used as references for comparisons.

A postoperative control 2D-TTE was performed.Results Out of 462 scallops/segments studied, surgical inspection identified 102 prolapses or flails (22%), 92 of which had previously been detected by 2D-TTE (90.2% sensitivity, 100% specificity).Agreement between preoperative 2D-TTE segmental analysis and SR was 97.8% (k = 0.

93; p Conclusions 2D-TTE, performed by an experienced echo-lab, has very good diagnostic accuracy in localizing the scallops/segments involved in degenerative MR, particularly for MASTICA CHIOS the middle ones (P2-A2), which represent almost the totality of prolapses.More invasive, time consuming and expensive exams should be reserved to selected cases.
