Enhanced Efficiency of Sequential Cutting Balloon Angioplasty in Calcified Coronary Artery Disease: The RODIN-CUT Technique.

Background: Heavily calcified coronary artery disease presents significant challenges in percutaneous coronary intervention (PCI), often requiring advanced techniques to achieve optimal outcomes. Cutting balloons (CB) have shown potential for plaque modification; however, their effectiveness is limited without standardized protocols.

Aims: This study introduces the RODIN-CUT technique, a novel approach utilizing sequential CB inflations with real-time intravascular ultrasound (IVUS) guidance.

Comprehensive Overview of Retrograde-Antegrade Connection Techniques Without Externalization in Chronic Total Occlusion PCI: The Portal Techniques.

Background: Advancing the retrograde microcatheter (MC) into the antegrade guide catheter during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can be challenging or impossible, preventing guidewire externalization.

Objectives: To detail and evaluate all the techniques focused on wiring to achieve intubation of the distal tip of a microcatheter, balloon, or stent with an antegrade or retrograde guidewire, aiming to reduce complications by minimizing tension on fragile collaterals during externalization and enabling rapid antegrade conversion in various clinical scenarios.

Methods: We describe the two main techniques, tip-in and rendezvous, and their derivatives such a facilitated tip-in, manual MC-tip modification, tip-in the balloon, tip-in the stent, deep dive rendezvous, catch-it and antegrade microcatheter probing.

Distal solution for an (un)conventional radial artery complication: a case report.

Background: The European Society of Cardiology guidelines recommend transradial access (TRA) for coronary angiography due to its advantages, including lower mortality and bleeding complications. Arterial pseudoaneurysms are rare but challenging complications of TRA, occurring in 0.009%-0.

Intravascular Ultrasound Assessment of Distal Trans-Radial Access in Patients Undergoing Percutaneous Coronary Intervention.

Background: Distal trans-radial access (dTRA) for percutaneous coronary interventions (PCI) is increasingly gaining attention due to its potential to mitigate radial artery occlusion (RAO). However, a comprehensive understanding of the mechanical impact of the devices on the radial artery (RA) wall remains limited. Using a complete intravascular ultrasound (IVUS) evaluation of the RA, including also the vascular access site, we aimed to evaluate all the consequences related to the catheterization on the RA wall, starting from the vascular access, comparing conventional sheath and sheathless approaches.

Surgical treatment of small-sized S3 arterio-venous malformations with neo-adjuvant and adjuvant bleomycin.

Arteriovenous Malformations are complex and challenging entities, and their treatment is often tailored on the patient. Interstitial sclerosing treatment with bleomycin is promising especially in cases where the aesthetical and/or functional burden of surgical intervention would be impactful as in the S3 AVM according to the SECg classification. We treated 15 patients presenting small (<10cm3) S3 arterio-venous malformations with 3 + 3 sessions of 15.

Extraperitoneal lateral pelvic sidewall excision: a novel rectal-sparing approach for lateral locally recurrent rectal cancer.

A rare case report of Erdheim-Chester disease with pericardial effusion, conduction abnormalities, and atrial infiltration.

Background: Erdheim-Chester disease (ECD) is a rare multisystem disorder that primarily affects adults. It is characterized by the excessive production and accumulation of histiocytes, a type of white blood cell, within multiple tissues and organs, including the cardiovascular system. The infiltration of histiocytes can cause a range of cardiovascular symptoms, including pericardial effusion, myocardial infiltration, and heart failure, among others.

Successful treatment by recross IVUS-guided reentry in coronary total occlusion: STRIVE-CTO.

Complex coronary total occlusion (CTO) lesions percutaneous treatment, especially in contexts where traditional antegrade strategies have failed and retrograde approaches are unsuitable, due to lack of interventional collaterals or high risk of complications, presents a considerable challenge for interventional cardiologists. Antegrade dissection reentry has historically offered a bailout strategy in cases with unsuccessful antegrade wire escalation. Nevertheless, the technique-whether employing dual-lumen microcatheters or dedicated reentry devices, such as Stingray-encounters several limitations, particularly when the delivery of the system is not possible, or extraplaque large hematomas, which complicates reentry.

Retrograde balloon hemostasis.

Despite improvements in current devices and techniques for complex chronic total occlusion (CTO) percutaneous coronary intervention (PCI), procedural complications, including coronary perforation, still occur and could be life-threatening. A patient with a history of multivessel coronary artery disease and a CTO of the right coronary artery (RCA) underwent successful retrograde crossing of an RCA CTO. After wiring the CTO body and lesion dilatation, a drug-eluting stent was implanted in the distal RCA toward the posterior descending artery.

ShOckwave ballooN or Atherectomy with Rotablation in calcified coronary artery lesions: Design and rationale of the SONAR trial.

Background: The percutaneous treatment of calcified coronary lesions remains challenging and is associated with worse clinical outcomes. In addition, coronary artery calcification is associated with more frequent peri-procedural myocardial infarction.

Study Design And Objectives: The ShOckwave ballooN or Atherectomy with Rotablation in calcified coronary artery lesions (SONAR) study is an investigator-initiated, prospective, randomized, international, multicenter, open label trial (NCT05208749) comparing a lesion preparation strategy with either shockwave intravascular lithotripsy (IVL) or rotational atherectomy (RA) before drug-eluting stent implantation in 170 patients with moderate to severe calcified coronary lesions.

Superior rectal artery preservation to reduce anastomotic leak rates in familial adenomatous polyposis patients treated with total colectomy and ileorectal anastomosis.

Background: Total colectomy with ileorectal anastomosis (TC/IRA) is one of the prophylactic surgical options in patients with familial adenomatous polyposis (FAP). This study investigated the effectiveness of superior rectal artery (SRA) preservation during TC/IRA in reducing anastomotic leakage (AL).

Methods: This retrospective study was based on prospectively collected data (01/2000 - 12/2022) at the National Cancer Institute, Milan, Italy.

SUOH 03 Guidewire for the Management of Coronary Artery Dissection: Insights from a Multicenter Registry.

Background: In the setting of coronary artery dissection, both spontaneous and iatrogenic, fixing the intimal tear, usually with stent implantation, can be extremely challenging if the distal wire position has been lost. Common complications are mainly related to the inadvertent subintimal tracking of the guidewire while attempting to gain the distal true lumen.

Aims: To report the registry results of using the SUOH 0.

Retrograde CTO-PCI Using an Internal Thoracic Bypass Graft Segment in a Patient with Acute Inferior ST-Elevation Myocardial Infarction and Cardiogenic Shock.

Background: Percutaneous coronary intervention (PCI) of the "culprit" artery is the recommended mechanical reperfusion strategy in the setting of ST-segment elevation myocardial infarction (STEMI). As PCI of bypass grafts may be associated with higher risks and lower procedural success rates, in patients with a history of previous coronary artery surgery, PCI directed at revascularization of the native vessels should be considered, but this may be difficult in the setting of a chronically occluded artery.

Case Presentation: A patient with a history of multivessel coronary artery disease and a chronic total occlusion (CTO) of the right coronary artery (RCA) requiring arterial bypass surgery, presented with an acute inferior STEMI and cardiogenic shock.

RailTracking: A Novel Technique to Overcome Difficult Anatomy During Transradial Approach.

Objective: We aim to investigate the safety and efficacy of a new technique, "RailTracking," in the management of challenging transradial routes during percutaneous coronary interventions (PCI).

Background: The transradial access (TRA) currently represents the access site of choice in PCI, but complex anatomy could lead to complications and access-site crossover. The assisted-tracking techniques described in the past (such as balloon-assisted tracking and pigtail-assisted tracking) are based on the concept of a "guiding tapered tip" to improve trackability.
