ISR vs De Novo Lesion Treatment During OCT-Guided PCI: Insights From the LightLab Initiative.

Background: Long-term outcomes after percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) are poor, yet limited granular procedural data exist evaluating lesion assessment, vessel treatment, and acute procedural outcomes.

Methods: The LightLab Initiative was a multicenter, prospective, observational study with contemporaneous procedural data collection during PCI procedures. Data were collected during PCIs performed by 48 interventional cardiologists at 17 US hospitals (2019-2021).

Transfemoral Transcatheter Mitral Valve Implantation With a Dedicated Device in a Rheumatic Mitral Stenosis Patient.

A 65-year-old obese woman with rheumatic heart disease and restrictive lung disease presented with decompensated heart failure. Evaluation demonstrated severely thickened mitral valve leaflets, severe mitral stenosis, and moderate mitral regurgitation. She underwent successful transfemoral transseptal transcatheter mitral valve replacement with a dedicated valve resulting in improved functional status.

Improving efficiency and operator proficiency during percutaneous coronary interventions utilizing a standardized optical coherence tomography workflow.

Objectives: This study was designed to compare efficiency and quality metrics between percutaneous coronary intervention (PCI) procedures using optical coherence tomography (OCT) guided by a variable workflow versus a standardized workflow in a real-world population.

Background: The LightLab (LL) Initiative was designed to evaluate the impact of a standardized OCT workflow during PCI to address barriers to adoption.

Methods: The LL Initiative was a multicenter, prospective, observational study.

One-Year Results of the Portico Transcatheter Aortic Heart Valve Using the Next-Generation FlexNav Delivery System.

Background: The FlexNav delivery system (DS) features a hydrophilic coating, stability layer, and integrated sheath to facilitate valve deployment in vessel diameters ≥5.0 mm.

Methods: Data were pooled from 2 concurrent prospective, multicenter, premarket studies (PORTICO IDE [n = 147] and FlexNav EU CE Mark [n = 46]) to evaluate the safety and efficacy of the FlexNav DS to deliver the Portico valve in the Global FlexNav study.

Duration of Dual Antiplatelet Therapy for Patients at High Bleeding Risk Undergoing PCI.

Background: The optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) among patients at high bleeding risk (HBR) is unknown.

Objectives: The purpose of this analysis was to compare 1 vs 3 months of DAPT in HBR patients undergoing drug-eluting stent implantation.

Methods: The XIENCE Short DAPT program comprised 3 prospective, multicenter, single-arm studies of HBR patients treated with a short DAPT course followed by aspirin monotherapy after PCI with a cobalt-chromium everolimus-eluting stent.

3- or 1-Month DAPT in Patients at High Bleeding Risk Undergoing Everolimus-Eluting Stent Implantation.

Objectives: The aim of this study was to evaluate 2 abbreviated dual-antiplatelet therapy (DAPT) regimens in patients at high bleeding risk (HBR) undergoing percutaneous coronary intervention (PCI).

Background: Current-generation drug-eluting stents are preferred over bare-metal stents for HBR patients, but their optimal DAPT management remains unknown.

Methods: The XIENCE Short DAPT program included 3 prospective, multicenter, single-arm studies enrolling HBR patients who underwent successful PCI with a cobalt-chromium everolimus-eluting stent.

Safety Profile of an Intra-Annular Self-Expanding Transcatheter Aortic Valve and Next-Generation Low-Profile Delivery System.

Objectives: The aim of this study was to characterize the safety profile of an intra-annular self-expanding valve with a next-generation low-profile delivery system (DS).

Background: Key design modifications to the FlexNav DS include the addition of a hydrophilic-coated, integrated sheath and stability layer to facilitate gradual, controlled deployment in vessels with diameter ≥5 mm.

Methods: Patients were pooled from 2 concurrent prospective, multicenter, single-arm studies (FlexNav DS arm of PORTICO IDE [Portico Re-Sheathable Transcatheter Aortic Valve System U.

Design and rationale of the XIENCE short DAPT clinical program: An assessment of the safety of 3-month and 1-month DAPT in patients at high bleeding risk undergoing PCI with an everolimus-eluting stent.

Dual antiplatelet therapy (DAPT) is key for the prevention of recurrent ischemic events after percutaneous coronary intervention (PCI); however, it increases the risk of bleeding complications. While new generation drug-eluting stents have been shown superior to bare-metal stents after a short DAPT course, the optimal DAPT duration in patients at high bleeding risk (HBR) remains to be determined. TRIAL DESIGN: The XIENCE Short DAPT program consists of three prospective, single-arm studies (XIENCE 90, XIENCE 28 Global and XIENCE 28 USA) investigating 3- or 1-month DAPT durations in HBR patients undergoing PCI with the XIENCE stent.

The State of the Absorb Bioresorbable Scaffold: Consensus From an Expert Panel.

Significant progress has been made in the percutaneous coronary intervention technique from the days of balloon angioplasty to modern-day metallic drug-eluting stents (DES). Although metallic stents solve a temporary problem of acute recoil following balloon angioplasty, they leave behind a permanent problem implicated in very late events (in addition to neoatherosclerosis). BRS were developed as a potential solution to this permanent problem, but the promise of these devices has been tempered by clinical trials showing increased risk of safety outcomes, both early and late.

Contemporary diagnosis of carotid fibromuscular dysplasia: role of power Doppler and a review of other diagnostic modalities.

Fibromuscular dysplasia (FMD) is a nonatheromatous, noninflammatory arteriopathy with segmental involvement of medium-sized arteries in multiple vascular beds. It most commonly involves the renal and carotid arteries. The etiology is unknown, although various hormonal and mechanical factors have been suggested.

Unexplained hemopericardium as a presenting feature of primary cardiac angiosarcoma: a case report and a review of the diagnostic dilemma.

This report describes a patient diagnosed with a cardiac angiosarcoma. The patient presented with cardiac tamponade. A pericardiocentesis revealed a bloody effusion, but cytology was nondiagnostic and a chest computed tomography showed only mediastinal lymphadenopathy.
