The prognostic value of exercise stress test after complex left main (LM) coronary artery bifurcation (LM) stenting has been poorly investigated. To partially fill this gap in knowledge, we retrospectively analyzed the procedural and medical data of consecutive patients referred to our center for complex LM bifurcation disease between January 2008 and May 2018 who were treated using either single- or dual-stenting techniques. The prognostic impact of an exercise stress test, performed 6 months after the coronary intervention, was evaluated in 502 patients (316 males, mean age 70.

Background: Data about the long-term performance of new-generation ultrathin-strut drug-eluting stents (DES) in challenging coronary lesions, such as left main (LM), bifurcation, and chronic total occlusion (CTO) lesions are scant.
Methods: The international multicenter retrospective observational ULTRA study included consecutive patients treated from September 2016 to August 2021 with ultrathin-strut (<70 µm) DES in challenging de novo lesions. Primary endpoint was target lesion failure (TLF): composite of cardiac death, target-lesion revascularization (TLR), target-vessel myocardial infarction (TVMI), or definite stent thrombosis (ST).

Introduction: Over the last 5 years, the armamentarium of the interventional cardiologist dealing with percutaneous closure of patent foramen ovale (PFO) has been enriched by some novel devices and further improvements of existing ones that have or promise to increase the safety and effective closure rate of PFO patients.
Areas Covered: This review presents and discusses recent advancements in device design and composition from both technical and clinical perspectives.
Expert Opinion: Device technology is continuously evolving.
Objectives: To assess the impact of conventional transcatheter heart valve (THV) commissural alignment techniques on THV/coronary overlap and coronary access (CA) after transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV).
Background: Specific Evolut Pro/Pro + and Acurate Neo2 THV orientations are associated with reduced neo-commissural overlap with coronary ostia in tricuspid aortic anatomy. Whether standard orientation techniques are effective also in the setting of BAV anatomy has not been studied.

Among the angiographic views used to evaluate left coronary system, the so-called "spider view" represents one of the most iconic, in particular for its ability to evaluate the Left Main stem (LM) and/or to guide percutaneous coronary interventions (PCIs) on LM bifurcation disease. Unfortunately, the use of such view is graved by a high X-ray exposure for both the operator and the patient. To overcome these limitations, we described an alternative coronary angiographic view, called "reverse spider" which is able to give more information about LM body and bifurcation disease with less X-ray exposure for the operator.

Technique: We performed, in a multidisciplinary team-work approach, an emergent ISF to correct the displacement of a physician-modified thoracic endograft released in the ascending aorta to correct a large anastomotic pseudoaneurysm in a patient who underwent ascending aorta replacement and subsequent LVAD implantation. We used a trans-septal needle device inserted through a direct access to the right carotid artery and performed an ISF to restore the patency of the outflow ostium of the LVAD.
Background: The impact of transcatheter aortic valve replacement (TAVR) leaflet design on long-term device performance is still unknown. This study sought to compare the clinical and hemodynamic outcomes of intra- (IA) versus supra-annular (SA) TAVR designs up-to 10-years following implantation.
Methods: Consecutive patients with at least 5-years follow-up following TAVR for severe symptomatic aortic stenosis from June 2007 to December 2016 were included.
Acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) is a life-threatening condition frequently encountered in patients with multivessel coronary artery disease (CAD). Despite prompt revascularization, in particular, percutaneous coronary intervention (PCI), and therapeutic and technological advances, the mortality rate for patients with CS related to AMI remains unacceptably high. Differently form a hemodynamically stable setting, a culprit lesion-only (CLO) revascularization strategy is currently suggested for AMI-CS patients, based on the results of recent randomized evidence burdened by several limitations and conflicting results from non-randomized studies.

We aimed to assess the features and predictors of access-site vascular complications in an unselected trans-femoral transcatheter aortic valve replacement (TF-TAVR) population.
Methods: Patients undergoing large bore arteriotomy closure with 18F MANTA VCD following TF-TAVR at a large tertiary care center from September 2019 to January 2021 were prospectively analyzed.
Background: Coronary access (CA) after transcatheter aortic valve replacement (TAVR) with supra-annular transcatheter heart valves (THV) can be challenging. Specific Evolut R/Pro and Acurate Neo THVs orientations are associated with reduced neo-commissure overlap with coronary ostia, while SAPIEN 3 THV cannot be oriented. With the ALIGN-ACCESS study (TAVR With Commissural Alignment Followed by Coronary Access), we investigated the impact of commissural alignment on the feasibility of CA after TAVR.

Observational data show that, in SCAD patients, both percutaneous coronary intervention and coronary artery bypass grafting seem to be hampered by higher technical complexity, lower success rates, and worse outcomes. As spontaneous healing is a common occurrence, expert consensus advices medical management of the acute phase, when feasible.

Recent Findings: Absorb BVS was burdened by intrinsic structural limitations which resulted in augmented rates of device thrombosis and clinical adverse events compared to current-generation metallic stent. Nevertheless, new generation devices with novel design and materials are in development.

To overcome the not negligible metallic drug-eluting stents adverse events rate, the polymeric or metallic bioresorbable scaffolds were designed to provide early drug delivery and mechanical support followed by complete resorption. However, the long-term evidence, focusing on the leading Absorb BVS technology, showed higher events compared with drug-eluting stents. This review discusses the lights and shadows of the current bioresorbable scaffolds according to their mechanical properties and biodegradation profile and suggests possible perspective on these technologies.

However, the displaced leaflets of the first THV will create a risk plane (RP) under which the passage of a coronary catheter will be impossible. The aim of our study was to evaluate the potential risk of impaired coronary access (CA) after TAVR-in-TAVR.

Background: Incidence of coronary access (CA) after transcatheter aortic valve replacement (TAVR) at long-term follow-up remains unknown. CA and percutaneous coronary intervention (PCI) after TAVR might present technical challenges, particularly with supra-annular devices.
Methods: Patients undergoing CA after being treated with TAVR at our institution were included in the study.
