Objectives: This study aimed to assess discordance between results of instantaneous wave-free ratio (iFR), fractional flow reserve (FFR), and intravascular ultrasound (IVUS) in intermediate left main coronary (LM) lesions, and its impact on clinical decision making and outcome.
Methods: We enrolled 250 patients with a 40%-80% LM stenosis in a prospective, multicenter registry. These patients underwent both iFR and FFR measurements.
Clinical validation of a 13-lead electrocardiogram derived from a self-applicable 3-lead recording for diagnosis of myocardial supply ischaemia and common non-ischaemic electrocardiogram abnormalities at rest.

Article Synopsis
- This study compares the diagnostic accuracy of a standard 12-lead ECG with a new 13-lead ECG using a device called RELF, which includes an additional lead designed to improve detection of ischemia.
- The research included 110 patients and 30 healthy subjects, with the findings showing that the 13-lead ECG achieved a higher accuracy of 77.4% for detecting myocardial ischemia compared to 76.8% for the standard 12-lead ECG.
- The RELF device is highlighted as a simple, self-applicable means of obtaining more effective diagnostic results for myocardial ischemia, demonstrating significant advantages over the traditional ECG method.
Background Dual axis rotational coronary angiography (DARCA) reduces radiation exposure during coronary angiography on older x-ray systems. The purpose of the current study is to quantify patient and staff radiation exposure using DARCA on a modality already equipped with dose-reducing technology. Additionally, we assessed applicability of 1 dose area product to effective dose conversion factor for both DARCA and conventional coronary angiography (CCA) procedures.

However, the time of ECG evaluation remains controversial. We aimed to compare the time course and dynamics of new onset ECG changes according to valve design in balloon- (BEV) and self-expandable (SEV) TAVR.

This multicenter study explored the feasibility and safety of His bundle pacing (HBP) in TAVR patients with a pacemaker indication to correct a TAVR-induced left bundle branch block (LBBB).
Methods: Patients qualifying for a permanent pacemaker implant after TAVR were planned for HBP implant.
