A 38-year-old woman underwent atriopulmonary Fontan surgery at age 18 years and subsequently successfully delivered a girl by cesarean section at age 34. Her condition later deteriorated due to atrial tachyarrhythmia and progressed to New York Heart Association (NYHA) class IV heart failure. Her treatment, at age 36, comprised total cavopulmonary connection conversion, direct right atrial ablation with bipolar radiofrequency devices, the creation of an atrial septal defect, and placement of a dual-chamber permanent pacemaker. Three years after the conversion, her condition has improved to NYHA class I. [ABSTRACT FROM AUTHOR]

During implantation of a pacemaker into a 15-year-old male (height: 155 cm, weight: 65 kg) suffering from complete atrioventricular block, it was difficult to exteriorize the myocardium by approaching from below the xiphoid process so an operative field was obtained by using a heart stabilizer. A myocardial electrode was fixed after confirming stable circulatory dynamics with no arrhythmia and good R wave amplitude and pacing thresholds. As the heart stabilizer is now a vital device for off-pump coronary artery bypass (OPCAB), we consider that it will also become a useful device for procedures other than OPCAB in the field of cardiac surgery.
