Resistant coronary lesions remain a challenge for modern angioplasty. Classical approaches include high-pressure inflations, prolonged inflations, or balloon oversizing. More recently, new technologies like rotablator, atherectomy, or laser have been proposed as adjunct to balloon angioplasty for the treatment of these specific lesions. However, all these technologies remain more difficult to handle, costly, and they do not offer long-term benefit over conventional methods. Therefore, a simple device such as the cutting balloon catheter which has been developed from a standard over the wire balloon catheter, may prove to be useful in resistant coronary lesions. We present our single center experience using the new cutting balloon catheter in six resistant lesions.

Drug-Coated Balloon-Based Treatment of Left Main True Bifurcation Lesion.
Catheter Cardiovasc Interv

Department of Internal Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Gangnam-gu, South Korea.
Background: There is a paucity of data regarding drug-coated balloon (DCB) treatment in the context of left main (LM) true bifurcation lesions.
Aims: The aim of this study was to evaluate the safety and efficacy of DCB-based treatment for unprotected LM true bifurcation lesions.
Methods: A total of 39 patients with LM true bifurcation lesion (Medina: 1,1,1/0,1,1/1,0,1) who were successfully treated with DCB alone or in combination with drug-eluting stent (DES) were retrospectively enrolled into the DCB-based group.
Severe aortic valve stenosis poses a significant risk for the aging population, often escalating from mild symptoms to life-threatening heart failure and sudden death. Without timely intervention, this condition can lead to disastrous outcomes. The advent of transcatheter aortic valve implantation (TAVI) has gained popularity, emerging as an effective alternative for managing severe aortic stenosis (AS) in high-risk patients experiencing deterioration of previously implanted bioprosthetic surgical aortic valves (SAV), which introduces complex challenges such as device compatibility and anatomical considerations.

Interventional Radiology (IR) can be a crucial player in managing placenta accrete spectrum disorder (PAS), offering minimally invasive angiographic techniques that can prevent or control hemorrhage and preserve fertility. These include prophylactic balloon occlusion of the aorta or iliac arteries, preoperative catheter placement in the iliac or uterine arteries for subsequent embolization, or pre-emptive arterial embolization preceding hysterotomy and delivery. This review provides obstetricians with an overview of IR's role in the management of PAS by describing specific endovascular techniques; existing outcomes data; and considerations for protocol development, preoperative planning, and intraoperative dynamics for when IR assists with PAS cases.

Background: Bioresorbable scaffolds (BRS) were developed to overcome limitations related to late stent failures of drug-eluting stents, but lumen reductions over time after implantation of BRS have been reported. This study aimed to investigate if lesion preparation with a scoring balloon compared with a standard noncompliant balloon minimizes lumen reduction after implantation of a Magmaris BRS assessed with optical coherence tomography and intravascular ultrasound.
Methods: Eighty-two patients with stable angina were randomized in a ratio of 1:1 to lesion preparation with a scoring balloon versus a standard noncompliant balloon before implantation of a Magmaris BRS.
Long-Term Bioprosthetic Valve Durability After Transcatheter Aortic Valve Replacement With Supra-Annular Self-Expanding Versus Intra-Annular Balloon-Expandable Valves in Patients With a Small Aortic Annulus.
Catheter Cardiovasc Interv

Department of Cardiovascular Medicine, Osaka University Graduate School of Medicine, Osaka, Japan.
Background: The long-term valve durability of supra-annular self-expanding valves (SEV) and intra-annular balloon-expandable valves (BEV) in patients with small aortic annuli remains unexplored.
Aims: This study aimed to determine the long-term bioprosthetic valve durability with SEV versus BEV in patients with small aortic annuli.
Methods: This retrospective study included patients with severe aortic stenosis (AS) and an aortic annulus area of 430 mm or less who underwent transcatheter aortic valve replacement using SEV and BEV between October 2009 and December 2022.
