Mortality in STEMI Patients With Cardiogenic Shock: Results From a Nationwide PCI Registry and Focus on Left Main PCI.

Background: The study aims to assess real-life short- and long-term outcomes of patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS). Outcome after left main (LM) PCI is of particular interest.

Methods: Procedural, 30-day, and >30-day mortality rates were assessed in 2744 CS-STEMI patients enrolled between 2012 and 2019 in a nationwide registry involving 49 centers.

Evaluation of a no-reference image quality metric for projection X-ray imaging using a 3D printed patient-specific phantom.

Purpose: Feasability of a no-reference image quality metric was assessed on patient-like images using a patient-specific phantom simulating a frame of a coronary angiogram.

Methods: One background and one contrast-filled frame of a coronary angiogram, acquired using a clinical imaging protocol, were selected from a Philips Integris Allura FD (Philips Healthcare, Best, The Netherlands). The background frame's pixels were extruded to a thickness proportional to their grey value.

Practice and long-term outcome of unprotected left main PCI: real-world data from a nationwide registry.

Background: Percutaneous coronary intervention (PCI) is increasingly performed in significant left main (LM) lesions. Left untreated, the prognosis is poor, but PCI and coronary bypass surgery (CABG) behold risks as well. Additional long-term outcome data might guide future treatment decisions.

Combining Optimized Image Processing With Dual Axis Rotational Angiography: Toward Low-Dose Invasive Coronary Angiography.

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.

Percutaneous transcatheter closure of an aorto-cardiac fistula in a six-year-old Warmblood mare with atrial fibrillation.

This report describes a rare case of an aorto-cardiac fistula in a six-year-old French Warmblood mare presented with atrial fibrillation, decreased performance, ventral oedema, bounding arterial pulsation and pathological jugular venous pulse. A 2.7-cm-diameter fistula connected the right aortic sinus of Valsalva to the right atrium.
