Abstract
A 31-year-old woman with a surgically corrected double outlet right ventricle and recurrent narrow QRS complex tachycardia was admitted to our hospital. The patient was scheduled for electrophysiology study. Coherent mapping identified the critical isthmus as a slow conduction area within posterolateral intercaval scar tissue. A continuous line of ablation was applied resulting in termination of the atrial tachycardia at the site of the critical isthmus from coherent mapping. Thus, coherent mapping facilitates complex ablation procedures and improves efficacy and efficiency.

Abstract
Abstract
Introduction
Cardiac arrhythmias are regulary seen in patients following orthotopic heart transplantation (OHT). So far, there is no data available about the prevalence in a large cohort.
Methods
We retrospectively screened our database for subjects with OHT who received inpatient or outpatient treatment in our center between January 2000 and December 2018. All these patients were carefully reviewed with special attention to rhythm disturbances after successful transplantation.
Results
We identified a total number of 1890 subjects with history of OHT being treated in our center during the pre-defined time-period. The prevalence of supraventricular tachycardias was as follows: atrial fibrillation/atypical flutter and atrial ectopy 10%, AV-node-re-entry tachycardia 3%, typical atrial flutter 2% and higher degree AV-Block or Sick-Sinus-Syndrom (SSS) was 6%. Sustained ventricular tachycardia or ventricular premature contractions were present in 2%. Regarding the patients with arrhythmias, 13% received catheter ablation for arrhythmias, thereof 53% an atrial ablation (24% left atrial ablation), the remainder received a ventricular ablation.
Conclusion
In this very large cohort and following a long observational time, there was a higher incidence of atrial arrhythmias in patients following OHT as reported in healthy subjects with an emphasis on atrial fibrillation and flutter. This data gives a valuable background information on morbidity following OHT.

Abstract
We report on the magnetic properties of monovacancy defects in neutron-irradiated graphite, probed by 13C nuclear magnetic resonance spectroscopy. The bulk paramagnetism of the defect moments is revealed by the temperature dependence of the NMR frequency shift and spectral linewidth, both of which follow a Curie behavior, in agreement with measurements of the macroscopic magnetization. Compared to pristine graphite, the fluctuating hyperfine fields generated by the defect moments lead to an enhancement of the 13C nuclear spin-lattice relaxation rate [Formula: see text] by about two orders of magnitude. With an applied magnetic field of 7.1 T, the temperature dependence of [Formula: see text] below about 10 K can well be described by a thermally activated form, [Formula: see text], yielding a singular Zeeman energy of ([Formula: see text]) meV, in excellent agreement with the sole presence of polarized, non-interacting defect moments.
