Complete heart block frequently requires emergency pacing to restore systemic perfusion. We report the case of a 3-yr-old girl undergoing interventional atrial septal defect closure who suffered from transient complete heart block with circulatory arrest. Transthoracic mechanical pacing for more than 3 min provided temporary support, sustaining an adequate cardiac output until sinus rhythm resumed.
BACKGROUND: Transcatheter coil closure (TCC) is safe and effective for most patients with PDA, but coil associated complications may occasionally be encountered. For occlusion of minimal PDA (<1 mm), we employed a closure protocol with guidewire and catheter manipulation. METHODS: Between April 2000 and September 2004, 38 patients with a minimal PDA were classified into two groups according to the occlusion method at our institution. Group A consisted of 11 patients (age range 0.7 to 3.5 years; mean age 1.6 years) who underwent guidewire and catheter manipulation. Group B consisted of 27 patients (age range 0.5 to 2.7 years; mean age 1.3 years) who underwent TCC of PDA. RESULTS: In group A (a PDA 0.4-0.9 mm), 9 (82%) patients had successful closure, and two (18%) patients failed the manipulation. No patient had complications during the procedure or follow-up. In group B (a PDA 0.5-0.9 mm), 26 (96%) patients had successful closure and 1 (4%) patient failed the attempt at TCC. No adverse events of coil closure was found during follow-up. Compared to the patients in group B, those in group A differed significantly in terms of procedure time. There were no significant differences in age, sex, body weight, PDA size, fluoroscopy time, success rate, and complication rate. CONCLUSIONS: Our results indicate that the manipulation is safe and effective for patients with minimal PDA. The manipulation technique can be tried before TCC in patients with minimal PDA.
AIMS: The purpose of this registry is to collect data on trends in interventional cardiology within Europe. Special interest focuses on relative increases and ratios in newer revascularization approaches and its distribution in different regions in Europe. METHODS AND RESULTS: Questionnaires distributed to delegates of the national societies of cardiology represented in the European Society of Cardiology to be completed by local institutions and operators yielded that 1637148 angiograms and 525983 coronary angioplasty (PTCAs) were performed in 2000. This is an increase of 15% and 23%, respectively, compared with 1999, particularly due to increases in eastern European countries. The population-adjusted PTCA rate rose from 714 procedures per 10(6) inhabitants in 1999 to approximately 800 procedures per 10(6) inhabitants in the year 2000. Coronary stenting increased by 26% to about 395000 stented cases in 2000. Complication rates remained unchanged, the need for emergency coronary artery bypass grafting (CABG) further decreased to 0.2% per percutaneous intervention. CONCLUSION: Interventional cardiology in Europe is still expanding, mainly due to rapid growth in countries with lower socioeconomical levels. Most central European countries reported only minor increases in procedures performed. Coronary stenting remains the only noteworthy adjunctive or alternative strategy to balloon angioplasty.
