Use of the Ostial Flash balloon in aorto-ostial chronic total occlusion percutaneous coronary intervention.

Background: The use of the Ostial Flash balloon (Ostial Corporation) has received limited study in aorto-ostial chronic total occlusion (CTO) percutaneous coronary artery intervention (PCI).

Methods: The authors evaluated the outcomes of Ostial Flash balloon use in a large CTO-PCI registry (PROGRESS-CTO, NCT02061436).

Results: The Ostial Flash balloon was used in 54 of 907 aorto-ostial CTO PCIs in 905 patients (6.

Association of Proximal Vessel Tortuosity with Technical Success and Clinical Outcomes: Analysis From the Progress-CTO Registry.

Background: Proximal vessel tortuosity can hinder wiring and equipment delivery during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Aims: We sought to examine the association of proximal vessel tortuosity with the short and long-term outcomes of patients undergoing CTO PCI.

Methods: We examined the association of proximal vessel tortuosity with clinical outcomes in patients who underwent CTO PCI at 50 US and non-US centers between 2012 and 2024.

Gynecology and obstetrics patients' attitudes towards body privacy: A cross-sectional-descriptive study.

Objective: It is extremely important for healthcare professionals to protect patients' privacy during diagnosis and treatment processes related to gynecology and obstetrics and to warn them in case patients' privacy is violated. This study was aimed at determining attitudes of female patients having obstetrics examination towards privacy and raising their awareness of privacy.

Methods: This cross-sectional-descriptive study was conducted with 410 patients who presented to the gynecology and obstetrics outpatient clinic of a university hospital.

Atomic Layer Deposition for Stable InP-Based On-Chip Quantum Dot microLEDs: Hybrid Quantum Dot Pockets.

Recent advances in synthesis techniques yield InP-based QDs with optical properties comparable to those of benchmark Cd-based QDs, making InP-based QDs viable alternatives to toxic Cd-based QDs for applications such as quantum dot LEDs (QLEDs). However, QLEDs typically suffer from a loss of luminescence over time due to exposure of the QDs to ambient air. To avoid this, state-of-the-art hybrid barrier layers are explored consisting of alternating organic/inorganic layers.

Intravascular Lithotripsy Versus Rotational Atherectomy in Coronary Chronic Total Occlusions: Analysis from the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention Registry.

There are limited comparative data on the use of plaque modification devices during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We compared intravascular lithotripsy (IVL) with rotational atherectomy (RA) for lesion preparation in patients who underwent CTO PCI across 50 US and non-US centers from 2019 to 2024. Of 15,690 patients who underwent CTO PCI during the study period, 436 (2.
