“…13,14 In the study by van Langenhove et al an underestimation of 20% point was observed for LVEF in comparison with LVA. However, in their study this was explained by an underestimation of EDV by EEM (69.1 ml vs. 125.9 ml), while there was far less difference in ESV.…”

“…Al-though there have been many studies focusing on the differentiation between viable and non-viable myocardium, to date only a few studies focusing on the diagnostic accuracy of EEM for assessment of global LV function have been published. 13,14 Therefore, we sought to investigate the diagnostic accuracy of EEM in a cohort of post-STEMI patients undergoing routine cardiac catheterisation.…”

Background. Little is known about the diagnostic accuracy of global LV function assessment by electromechanical endocardial mapping (EEM). The aim of the present study was to determine the relationship between global left ventricular (LV) function measured by EEM and biplane left ventricular contrast angiography (LVA) after ST-elevation myocardial infarction (STEMI).Methods. Thirty-seven patients underwent LVA and EEM during routine coronary angiography four months after primary percutaneous intervention for STEMI. Global LV function parameters were available from both techniques in all patients. LVA was regarded as reference standard.Results. All procedures were carried out without adverse events. Average age was 55+/-10 years and 84% were male. EEM showed an overestimation of end-diastolic volume (EDV) and end-systolic volume (ESV) of 6.5 ml and 25.5 ml, respectively. Correlation (r) was 0.84 (p<0.001) for EDV and 0.74 (p<0.001) for ESV. Average left ventricular ejection fraction (LVEF) measured by EEM was 17.2% point (+/-11.3% point) lower compared with LVA (r=0.69, p<0.001).Conclusion. Although global functional parameters by EEM correlated well with LVA, the relatively large differences in terms of absolute values for ventricular volumes and LVEF render the two techniques non-interchangeable for global LV-function-data.

“…The mapping procedure is based on dragging the catheter along the endocardium and sequentially acquiring the location of the tip and local electrograms while in stable contact with the endocardium. The 3-D maps are constructed by combining and integrating the information from the intracardiac electrograms with the respective endocardial locations (Grothues et al 2006).…”

Common-type atrial flutter (AFL) is a type of atrial tachyarrhythmia with counterclockwise rotation around the tricuspid annulus within the right atrium (RA). It was recently reported that the electrogram voltage reduction observed in the RA was involved in the development of AFL. However, the relationship between the low voltage areas and conduction velocity during AFL has not been fully described. In this study, patients with AFL (n = 17) and without AFL (n = 4) were examined using an electro-anatomical mapping system. The patients with AFL were divided into 2 groups; AFL group (n = 8) and coronary sinus ostium (CSO) group (n = 9). The AFL group was defined as exhibiting the maintenance of AFL and the CSO group sinus rhythm before the catheter ablation. The electrogram voltages of each area in the RA (septum, and posterior and lateral walls), conduction velocity during AFL and transverse and longitudinal conduction velocities were evaluated. In the septum, the mean electrogram voltage was significantly lower in the AFL and CSO groups than in the group without AFL. Moreover, the conduction velocity during AFL was significantly slower in the septum, and both the septal transverse and longitudinal conduction velocities were significantly slower in the AFL and CSO groups than in the group without AFL. In conclusion, these findings suggest that both the slower conduction velocities and lower voltage in the RA septum may be involved in the development of AFL. Thus, ablation of the RA septum may represent a therapeutic approach of AFL. atrial flutter; atrial septum; catheter ablation; conduction velocity; bipolar voltage. Tohoku

Volume measurement by CARTO™ compared with cardiac magnetic resonance

Abstract: Although CMR and CARTO showed a good correlation in the measurement of RVEDV and LVEDV in a group of heart failure patients, the clinical interchangeability of the two methods may be questioned.
