Tetralogy Of Fallot Repair

ABSTRACT Introduction Incidence of right ventricular (RV) dysfunction in early postoperative period after Tetralogy of Fallot (TOF) repair ranges from 28 to 63%. Echocardiography is the first-line tool for the assessment of RV function in early postoperative period. As speckle tracking echocardiography (STE) has emerged as a new promising tool for assessing myocardial performance and is independent of geometric assumptions and angle dependence, it is more sensitive for detecting changes in myocardial performance than conventional echocardiographic parameters of RV function. The current study demonstrates echocardiographic parameters assessed by conventional two-dimensional (2D) echocardiography and STE in patients before and after TOF repair. Materials and methods Fifty-nine consecutive patients planned for complete intracardiac repair for TOF were enrolled in this prospective cohort study. The 2D echocardiography and STE were performed a day prior to TOF repair, in the early postoperative period between days 3 and 7 and after discharge at 3 months. Results The median age of patients was 6 years, with 57.6% males (34/59). Baseline hemoglobin and room air oxygen saturation were 17.7 ± 3.7 gm% and 79.4% ± 8% respectively. Two patients did not survive the procedure (3.4%). Right ventricular longitudinal peak systolic strain (RV LPSS) in early postoperative period was significantly decreased in all segments of both septal and lateral wall. However, RV LPSS assessed at midterm follow-up at 3 months postoperatively significantly improved in all segments of RV compared with assessment done in the early postoperative period, and was significantly better than preoperative values in all three segments of the septal wall. Conclusion Our study shows that the use of 2D strain or speckle tracking is a feasible and easy-to-implement technique for the evaluation of RV function after TOF repair.

Abstract. Background: The purpose of this observational study is to report the six-month clinical outcomes with a new multiple stent delivery system in patients with femoro-popliteal lesions. Patients and methods: The LOCOMOTIVE study is an observational multicentre study with a primary endpoint target lesion revascularization (TLR) rate at six months. Femoro-popliteal lesions were prepared with uncoated and/or paclitaxel-coated peripheral balloon catheters. When flow limiting dissections, elastic recoil or recoil due to calcification required stenting, up to six short stents per delivery device, each 13 mm in length, were implanted. Sonographic follow-ups and clinical assessments were scheduled at six months. Results: For this first analysis, a total of 75 patients 72.9 ± 9.2 years of age were enrolled. The majority of the 176 individually treated lesions were in the superficial femoral artery (76.2 %, 134/176) whereas the rate of TASC C/D amounted to 51.1 % (90/176). The total lesion length was 14.5 ± 9.0 cm with reference vessel diameters of 5.6 ± 0.7 mm. Overall 47 ± 18 % of lesion lengths could be saved from stenting. At six months, the patency was 90.7 % (68/75) and all-cause TLR rates were 5.3 % (4/75) in the overall cohort. Conclusions: The first clinical experience at six months suggests that the MSDS strategy was safe and effective to treat femoro-popliteal lesions of considerable length (14.5 ± 9.0 cm). Almost half of the lesion length could be saved from stenting while patency was high and TLR rates were acceptably low.
