ABSTRACT
BACKGROUND:
Covered stent correction of sinus venosus ASDs (SVASD) is a relatively new technique. Challenges include anchoring a sufficiently long stent in a nonstenotic superior vena cava (SVC) and expanding the stent at the wider SVC-RA junction without obstructing the anomalous right upper pulmonary vein (RUPV). The 10-zig covered Cheatham-platinum (CCP) stent has the advantage of being available in lengths of 5-11 cm and dilatable to 34 mm in diameter.METHODS:
An international registry reviewed the outcomes of 10-zig CCP stents in 75 patients aged 11.4-75.9 years (median 45.4) from March 2016. Additional stents were used to anchor the stent in the SVC or close residual shunts in 33/75. An additional stent was placed in 4/5 (80%) with 5/5.5 cm CCPs, 18/29 (62%) with 6 cm CCPs, 5/18 (28%) with 7 cm CCPs, 5/22 (23%) with 7.5/8 cm CCPs and 0/1 with an 11 cm CCP. A "protective" balloon catheter was inflated in the RUPV in 17.RESULTS:
Early stent embolization in two patients required surgical removal and defect repair and tamponade was drained in one patient. The CT at 3 months showed occlusion of the RUPV in one patient. Follow up is from 2 months to 5.1 years (median 1.8 years). QPQS has reduced from 2.5 ± 0.5 to 1.2 ± 0.36 (p < .001) and RVEDVi from 149.1 ± 35.4 to 95.6 ± 21.43 ml/m2 (p < .001).CONCLUSIONS:
Ten-zig CCPs of 7-8 cm appear to provide reliable SVASD closure with a low requirement for additional stents. Careful selection of patients and meticulous attention to detail is required to avoid complications.Palavras-chave
