Background: Decreasing the amount of iodinated contrast is an important safety aspect of percutaneous coronary interventions (PCI), particularly in patients with a high risk of contrast-induced acute kidney injury (CI-AKI). Dynamic Coronary Roadmap (DCR) is a PCI navigation support tool projecting a motion-compensated virtual coronary roadmap overlay on fluoroscopy, potentially limiting the need for contrast during PCI.
Aims: This study investigates the contrast-sparing potential of DCR in PCI, compared to standard angiographic guidance.
• Hypertrophic cardiomyopathy is a common genetic heart disease. • Patients can have variable clinical manifestations and severity of disease. • Manifestations include LVOT obstruction and MR.

However, bail-out stenting may be necessary in cases of suboptimal angioplasty. This study investigated the outcomes of femoropopliteal disease treated with DCB with/without bail-out stenting.

Experts have advocated for a collaborative 2-operator approach to support intraprocedural decision-making for these complex interventions. The impact of a second operator on patient and procedural outcomes is unknown.

This has in turn affected the training experience of cardiology fellows, including diminished procedure numbers and a narrow breadth of cases as they approach the end of their training before joining independent practice. It has also taken a toll on the emotional well-being of fellows as they see their colleagues, loved ones, patients or even themselves struggling with COVID-19, with some succumbing to it.

While dissections are known to affect patency and reintervention after balloon angioplasty, the association between dissections and major adverse limb event (MALE) after drug-coated balloon (DCB) angioplasty remains uncertain. Thus, the postangioplasty dissection and bailout stenting patterns were investigated.

Objective: To develop and validate a scoring system that can adequately predict successful anterograde crossing of infrapopliteal CTOs.
Amiodarone is a one of the most commonly used antiarrhythmic drug with efficacy in both supraventricular and ventricular tachycardia. Hepatic, pulmonary, and thyroid adverse effect profiles of this drug are well described and mandate a close follow-up. We report a case of amiodarone-related hyponatremia, which is one of the rarest side effects associated with this medication and our case was unlike other previous case reports because severity of symptoms required hemodialysis for correction of hyponatremia despite trying dose reduction strategy.

Method: Polysomnography (PSG) and actigraph measures as well as assessments of subjective sleep parameters were examined in children before and after treatment with either LDX or placebo in a randomized, double-blind, single-center, parallel-group study.
Results: There was no statistically significant increase in the primary endpoint of latency to persistent sleep (LPS) for the LDX-treated group compared to the placebo group.
