Objectives: There are few studies evaluating serial changes in tissue Doppler imaging parameters in acute pulmonary thromboembolism. We aimed to compare these changes in male and female patients separately.

Methods: Between September 2010 and September 2011, 41 of 64 hemodynamically stable acute patients with pulmonary thromboembolism were included in the study. Twenty-two healthy individuals served as a control group.

Results: Compared to the control group, the acute pulmonary thromboembolism group had a lower tricuspid annular plane systolic excursion, basal peak systolic velocity of the tricuspid valvular annulus, right ventricular (RV) peak systolic strain, and RV peak systolic strain rate and a higher RV diameter, peak systolic pulmonary artery pressure, and RV myocardial performance index (P < .05). Values for these parameters were not different between men and women in the patient group. In men, compared to admission, predischarge echocardiography showed significant improvement in the tricuspid annular plane systolic excursion (mean ± SD, 16.08 ± 4.33 versus 19.29 ± 3.74 mm; P = .002), basal tricuspid annular peak systolic velocity (10.11 ± 3.66 versus 11.66 ± 3.38 cm/s; P = .007), and peak systolic strain (-13.00% ± 14.99% versus -23.20% ± 10.23%; P = .001), whereas in women, predischarge and 3-month follow-up echocardiography showed marked improvement in the tricuspid annular plane systolic excursion (17.50 ± 4.88 versus 19.79 ± 5.58 mm; P = .021) and peak systolic strain (-15.70% ± 13.52% versus -21.01% ± 10.57%, respectively; P= .045). Female patients did not show improvement in these parameters during hospitalization.

Conclusions: Patterns of changes in the RV function over time during a 3-month follow-up might differ between male and female patients with acute pulmonary thromboembolism, and the recovery process could be slower in women. Moreover, the midventricular peak systolic strain might be useful for serial evaluation of the recovery process.

Late diagnosis of large left ventricular pseudoaneurysm after mitral valve replacement and coronary artery bypass surgery by real-time three-dimensional echocardiography.

J Tehran Heart Cent 2012 Nov 30;7(4):188-90. Epub 2012 Nov 30.

One of the most serious complications of mitral valve replacement is left ventricular rupture and pseudoaneurysm formation, which is rare but potentially lethal. We herein present a late type of post mitral valve replacement and coronary artery bypass surgery pseudoaneurysm in a 74-year-old female, who was admitted to our hospital with a recent history of exertional dyspnea. She had the above-mentioned operation 10 months before. The diagnosis was made via two-dimensional and real-time three-dimensional transthoracic echocardiography. The prosthetic mitral valve was removed, and the large orifice of the pseudoaneurysm was closed by surgery. At one year's follow-up, the patient was in good condition.
