ABSTRACT
INTRODUCTION:
Transseptal puncture (TSP) is routinely performed for left heart intervention, but it can sometimes be complex and life-threatening. This study introduced a safe and effective method to facilitate TSP for left atrial access. METHODS ANDRESULTS:
A total of 200 patients (190 with atrial fibrillation, 10 with a left accessory pathway) were prospectively analyzed. In the guidewire group, TSP was performed using a SWARTZ sheath and a Brockenbrough needle with a 0.014-inch coronary guidewire instead of an inner stylet. The needle tip position was confirmed by pushing the guidewire into the left superior pulmonary vein after initial puncture in 100 patients. In the contrast group, TSP was performed in 100 patients using standard devices by injecting contrast to confirm needle-tip position. Left atrial access was achieved successfully in all patients in the two groups without serious complications. The guidewire group showed a higher first-pass rate for left atrial access compared with the contrast group (81.1% vs. 75% p < .001, respectively).CONCLUSION:
Coronary guidewire TSP is safe and is associated with a high success rate, and it is thus a useful alternative to conventional TSP. This method is useful for patients with septal aneurysms and contrast allergies.Palavras-chave
