[When orbital exceeds its limits!].

High calcified PCI are challenging because immediate and follow-up results are not optimal. We recommend using a specific preparation of these lesions, especially using atherectomy which can itself provide complications. We illustrate our comments with a clinical case where we have decided to treat a long-calcified lesion from left main to distal left artery descending with a specific preparation according orbital atherectomy.

Sodium Chloride Physiological Saline Solution Versus Water Preparations Injectable in the Use of Shockwave Intravascular Lithotripsy: A Single-Center Experience.

Background: Shockwave intravascular lithotripsy (IVL) coronary system is a very useful new technology for severely calcified coronary artery plaques before percutaneous coronary intervention (PCI). The device uses a semi-compliant low-pressure balloon, integrated into a sterile catheter, to deliver by vaporizing fluid an expanding bubble that generates high-pressure ultrasonic energy by waves that create multiplane longitudinal micro-macro fractures in calcified plaques, which facilitate optimal stent placement and expansion, and luminal gain.

Methods: The use of Shockwave IVL coronary system in our cardiac catheterization laboratory (Cath lab) at the "Clinique Saint-Hilaire" in Rouen, France, started in March 2019, with 42 procedures performed since this date: two patients in 2019, two patients in 2020, seven patients in 2021, 23 patients in 2022, and eight patients since the beginning of 2023.

A direct wire pacing device for transcatheter heart valve and coronary interventions: a first-in-human, multicentre study of the Electroducer Sleeve.

Background: Transcatheter aortic valve implantation (TAVI) and complex percutaneous coronary interventions (PCI) may require cardiac pacing during device delivery, generally requiring the insertion of a temporary pacing lead via an additional venous access site. The purpose-built Electroducer Sleeve device provides direct wire pacing without the need for a temporary venous pacemaker.

Aims: This study assessed the safety of temporary cardiac pacing using the novel sleeve device during PCI.

Impact of Sex on Clinical Outcomes in Patients undergoing Complex Percutaneous Coronary Angioplasty (from the e-ULTIMASTER Study).

Female gender has been shown to be associated with worse clinical outcomes after percutaneous coronary intervention (PCI). However, the impact of gender on the clinical outcomes of complex PCI is still poorly understood. This study examined the differences in patient and coronary lesion characteristics and longer-term clinical outcomes in male and female patients who underwent complex PCI.

[Imaging and radial approach].

Radial approach allows in a large majority of cases to perform endovascular imaging. If we can assess anatomical variations with angiography, echography approach begins a mandatory tool to do the puncture safely, but also allows to identify anatomical variations and complications.

Prognosis of PCI in AMI setting in the elderly population: Outcomes from the multicenter prospective e-ULTIMASTER registry.

Background: Elderly patients with ST-elevation myocardial infarction (STEMI) who undergo percutaneous coronary intervention (PCI) are usually excluded from major trials.

Hyopthesis: This study sought to assess 1-year clinical outcomes following PCI with a drug-eluting stent in patients older than 80 years old with STEMI.

Methods: The large all-comer, multicontinental e-ULTIMASTER registry included 7507 patients with STEMI who underwent PCI using the Ultimaster stent.

Mid-term outcome of de novo lesions vs. in stent restenosis treated by intravascular lithotripsy procedures: Insights from the French Shock Initiative.

Background: Intravascular lithotripsy (IVL) is a promising new technology for disrupting de-novo calcified coronary lesions (DNL) before percutaneous coronary intervention (PCI). We assessed 12-month outcomes of IVL in patients undergoing PCI for DNL or intra stent restenosis (ISR) lesions related to device underexpansion.

Methods: Prospective analysis of patients in the multicentre all-comers French Shock Initiative IVL registry.

Best Practice in Intravascular Lithotripsy.

Intravascular lithotripsy (IVL) is a novel approach to lesion preparation of severely calcified plaques in coronary and peripheral vessels. Lithotripsy is delivered by vaporising fluid to create an expanding bubble that generates sonic pressure waves that interact with arterial calcification. Available data indicate that IVL leads to increased vessel compliance before stent implantation with high efficacy and an excellent safety profile.

Direct Wire Pacing for Challenging Left Main Stenting: An Old Technique Revived.

During stent positioning after predilating with a non-compliant balloon, we observed major motion of our device in the left main coronary artery. Under those conditions, accurate stent placement was uncertain. To remedy this situation, we decided to perform a rapid direct wire pacing with a good final angiographic result.

[Why and how do I use the orbitalatherectomy ?].

Severe coronary artery calcification, too often underestimated, increases the complexity of percutaneous coronary interventions. Atherectomy is one of preferred approach for the preparation of calcified lesions before stent placement. Orbital atherectomy (OA) is a new method that has proven to be safe and effective in the preparation of calcium plaques (ORBIT I and ORBIT II studies).

[Infection and TAVI].

Since trans-catheter valve implantation (TAVI) has emerged for severe symptomatic aortic stenosis treatment, infective endocarditis (IE) appears as a rare but severe complication. Like surgical aortic valve remplacement infective endocarditis (SAVR-IE), TAVI-IE has a noxious impact on morbidity and mortality. Compared to SAVR-IE, TAVI-IE present some similarities as well as differences.

[Radial artery occlusion ofter coronarography: is it really a problem?].

The use of transradial access for cardiac procedures has increased worldwide over the past two decades. Despite the many advantages this technique offers, there remains some concern that radial artery occlusion, a potential complication of radial cannulation, might lead to significant ischemic sequelae in the hand. This paper reviews the major causes, its possible consequences and the strategies for its prevention and treatment.
