TL;DR: QFR had good correlation and agreement with FFR and high diagnostic performance in the evaluation of intermediate coronary stenosis, suggesting that QFR may be an alternative tool for estimating myocardial ischemia.

TL;DR: QFR including onsite analysis demonstrated a good correlation with iFR and a diagnostic performance comparable to that of iFR in consecutive patients with intermediate coronary stenosis, suggesting its potential as a rapidly derived index for evaluating myocardial ischaemia in clinical settings.

TL;DR: In this paper, the authors described a rare case of left ventricular (LV) free wall perforation by an RV lead and the management of this complication and considered that some features of the lead (SelectSecure 3830-69, Medtronic) may be related to this complication.

TL;DR: A 78-year-old woman with a past history of breast cancer was referred to a hospital for further examination of multiple cardiac tumors, and all 4 tumors were myxomas, although the patient did not meet the diagnostic criteria of the Carney complex.

TL;DR: The electrophysiological study disclosed the coexistence of focal AT originating from coronary sinus (CS) with slow-fast AVNRT, and found that atrial pacing never provoked slow- fast AVN RT with isoproterenol infusion whereas ventricular pacing did, which depends on the physiological characteristic of the dual AV nodal pathway.
