A 52-year-old woman with atrial fibrillation, thrombocytopenia, and severe gastrointestinal bleeding while on several anticoagulants was referred for left atrial appendage closure. A year earlier, pulmonary vein ablation had been attempted but femoral access proved impossible due to a previously undetected congenital interruption of the inferior vena cava (figure 1A; asterisk). A right transjugular procedure was planned under general anesthesia and guided by transesophageal echocardiography and computed tomography-fluoroscopy fusion imaging (video 1 of the supplementary data). The left atrial appendage had a windsock morphology, with a mean diameter of 20 mm at the landing zone and 30 mm at the ostium (figure 1B,C). Consequently, a 24 mm x 30 mm LAmbre LAA Occluder system (LifeTech Scientific, China) was used, because its secure anchorage and closure mainly through the disk could facilitate the procedure. Transseptal puncture was performed using an SL1 sheath and a BRK-1 XS needle (Abbott, United States) by pre-shaping a secondary curve, followed by the insertion of a SafeSept guidewire (Pressure Products, United States) specifically designed for greater accuracy of transseptal puncture (figure 2A,B; the asterisk indicates the posterior and mid-puncture. Ao, aorta; LAA, left atrial appendage; SVC, superior vena cava). The device was implanted through a 10-Fr... |
