Aims: Increased medial mitral annulus early diastolic velocity (e′) plays an important role in the echocardiographic diagnosis of constrictive pericarditis (CP) and mitral e′ velocity is also a marker of underlying myocardial disease. We assessed the prognostic implication of mitral e′ for long-term mortality after pericardiectomy in patients with CP. Methods and results: We studied 104 surgically confirmed CP patients who underwent echocardiography and cardiac catheterization within 7 days between 2005 and 2013. Patients were classified as primary CP (n = 45) or mixed CP (n = 59) based on the clinical history of concomitant myocardial disease. On multivariable analysis, medial e′ velocity and mean pulmonary artery pressure were independently associated with long-term mortality post-pericardiectomy. There were significant differences in survival rates among the groups divided by cut-off values of 9.0 cm/s and 29 mmHg for medial e′ and mean pulmonary artery pressure, respectively (both P < 0.001). Ninety-two patients (88.5%) had elevated pulmonary artery wedge pressure (PAWP) (≥15 mmHg); there was no significant correlation between medial E/e′ and PAWP (r = 0.002, P = 0.998). However, despite the similar PAWP between primary CP and mixed CP groups (21.6 ± 5.4 vs. 21.2 ± 5.8, P = 0.774), all primary CP individuals with elevated PAWP had medial E/e′ <15 as opposed to 34 patients (57.6%) in the mixed CP group (P < 0.001). Conclusion: Increased mitral e′ velocity is associated with better outcomes in patients with CP. A paradoxical distribution of the relationship between E/e′ and PAWP is present in these patients but there is no direct inverse correlation between them.
