Pericardial tamponade occurred 3 days after the catheter closure of an atrial septal defect (ASD) using Amplatzer Septal Occluder (St. Jude Medical, St. Paul, MN, USA). Before the closure, two-dimensional and real-time three-dimensional transesophageal echocardiography demonstrated a deficient aortic rim and atrial septal malalignment. Perforation of the right atrium toward the non-coronary sinus of the aortic root was confirmed at the emergent surgery. Cardiac erosion is one of the most catastrophic complications in ASD patients undergoing catheter closure with Amplatzer Septal Occluder. Hence, several risk factors for this complication are discussed and identified. Oversized device deployment and a deficient aortic rim are accepted factors potentially causing cardiac erosion. Besides, atrial septal malalignment, which is a morphological characteristic of ASD, may be a novel risk factor for cardiac erosion. <Learning objective: Cardiac erosion is a potentially lethal complication when catheter closure of atrial septal defects using Amplatzer Septal Occluder (St. Jude Medical, St. Paul, MN, USA) is provided to the patients. However, mechanisms of this complication remain to be completely elucidated. Atrial septal malalignment may be one of the novel risk factors for this catastrophic complication.>.

Although numerous studies have shown an association between a patent foramen ovale (PFO) and cryptogenic cerebrovascular accidents (CVA), there has been no definitive control study that demonstrated the benefit of percutaneous device closure of a PFO compared to medical therapy in patients with CVA. Additionally, few clinical data exist for Japanese patients in this field. We demonstrate the initial experiences in catheter closure of a PFO as secondary prevention of CVA in Japan. Catheter closure of a PFO was attempted in 7 patients who were diagnosed with cryptogenic CVA. Mean age at the procedure was 54 ± 19 years. The presence of spontaneous interatrial right-to-left shunts was demonstrated by transesophageal contrast echocardiography without Valsalva maneuver in all of the patients. Amplatzer Cribriform device (n = 4) or Amplatzer PFO Occluder (n = 3) was used for the procedure and was successfully deployed. Device-related complications were not observed at the time of the procedure or during the follow-up period (mean period of 16 ± 9 months). Catheter closure of a PFO could be safely performed with Amplatzer Cribriform or Amplatzer PFO Occluder. This procedure may contribute to prevention of recurrent cryptogenic CVA in Japanese patients.

症例は62歳、男性。早朝の苦悶様呼吸に続く呼吸停止疑いのため近医受診し、Brugada症候群疑いにて当院紹介入院。心電図では完全右脚ブロックを合併することもありBrugada型心電図との診断が容易ではなかった。電気生理学的検査時、ピルジカイニド1mg/kgを投与したが、やはり明瞭なBrugada型波形が得られないため、完全右脚ブロックの状態を是正する目的で右室心尖部より単発早期刺激を加えた。すると刺激間隔の短縮に伴いcoved型そしてsaddleback型の比較的明瞭なBrugada型心電図を得ることができた。完全右脚ブロックを伴いBrugada型心電図の診断が困難であったが右室心尖部単発早期断激によりBrugada型心電図が明瞭化され、また、相対的な右室伝導遅延の改善に伴いcoved型からsaddleback型に心電図が変化したBrugada症候群の1例を経験したので報告する。(著者抄録)

OBJECTIVES: To evaluate the efficacy and safety of transcatheter closure of atrial septal defects (ASD) in patients over 70 years of age. BACKGROUND: Transcatheter closure of ASD is an established procedure in children and young adults, but the benefits of this procedure in geriatric patients are still unclear. METHODS: Between 2005 and 2010, 430 patients with ASD underwent transcatheter closure in our hospital. Among those patients, 30 consecutive patients older than 70 years of age were prospectively evaluated. RESULTS: Mean age at procedure was 75.8 ± 3.8 years (range: 70-85 years). Mean Qp/Qs was 2.4 ± 0.7 and mean ASD diameter was 20.3 ± 6.4 mm. Nine patients (30%) had a history of hospitalization due to heart failure. ASD closure was successfully performed in 28 patients (93%) without significant complications. During the follow-up period (mean period of 19.1 ± 11.3 months), New York Heart Association (NYHA) functional class was significantly improved in 20 patients (74%). Significant improvements of plasma BNP level, resting heart rate, and systolic pulmonary artery pressure were also observed. Improvement of tricuspid regurgitation was observed in 11 of 17 patients with moderate or severe regurgitation during the follow-up period. Conversely, worsening of mitral regurgitation was observed in 10 of the 27 patients. CONCLUSION: Transcatheter closure of ASD in geriatric patients can be performed safely. This procedure contributes to significant improvement of symptoms and positive cardiac remodeling. Long-term follow-up is mandatory, especially for patients with mitral regurgitation.
