Cardiovascular Revascularization Medicine : Including Molecular Interventions

BACKGROUND: Coronary functional testing to formally diagnose coronary microvascular dysfunction (CMD) reduces cardiovascular events and alleviates angina. This study aims to investigate the extensive and complex journey that patients with CMD undergo, from the onset of chest pain to eventual diagnosis. METHODS: Data from the Coronary Microvascular Disease Registry (CMDR) were analyzed, including information on the date of first documentation of chest pain, number of non-invasive and invasive tests the patient underwent, emergency department visits, and hospitalizations...

BACKGROUND: Coronary microvascular dysfunction (CMD) is a prevalent condition among patients with cardiovascular risk factors, leading to a reduced quality of life and an increased risk of major adverse cardiovascular events. Novel invasive techniques have emerged to more accurately diagnose CMD. However, CMD's natural history remains poorly understood due to limited data. To address this knowledge gap, the Coronary Microvascular Disease Registry (CMDR) was established with the primary aim of standardizing comprehensive coronary functional testing and understanding of CMD...

BACKGROUND: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. METHODS: Analysis of primary and secondary endpoints at two years of follow-up was prespecified in the study protocol...

BACKGROUND: Limited data are available regarding myocardial injury and its risk factors in percutaneous coronary interventions (PCI) of severe calcified lesions using orbital atherectomy (OA). METHODS: Patients who underwent OA at our institution were retrospectively enrolled into the present registry. High-sensitive Troponin I (hsTroponin I), EKG and echocardiography were used to assess myocardial injury after the procedure. RESULTS: A total of 27 patients between who underwent OA between January 2022 and June 2023 were included...

INTRODUCTION: Mitral valve stenosis (MS) can be concomitantly present in patients undergoing Transcatheter Aortic Valve Implantation (TAVI). Some studies have reported up to one-fifth of patients who underwent TAVI also have MS. The relationship between mitral stenosis and TAVI has led to concerns regarding increased adverse cardiac outcomes during and after the procedure. METHODS: The Nationwide Readmission Database (NRD 2016-2019) was utilized to identify TAVI patients with MS with ICD-10-CM codes...

BACKGROUND: There has been an evolution in the disease severity and complexity of patients presenting to the cardiac intensive care unit (CICU). There are limited data evaluating the role of palliative care in contemporary CICU practice. METHODS: PubMed Central, CINAHL, EMBASE, Medline, Cochrane Library, Scopus, and Web of Science databases were evaluated for studies on palliative care in adults (≥18 years) admitted with acute cardiovascular conditions - acute myocardial infarction, cardiogenic shock, cardiac arrest, advanced heart failure, post-cardiac surgery, spontaneous coronary artery dissection, Takotsubo cardiomyopathy, and pulmonary embolism - admitted to the CICU, coronary care unit or cardiovascular intensive care unit from 1/1/2000 to 8/8/2022...

BACKGROUND: The role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) who subsequently undergo transcatheter aortic valve replacement (TAVR) remains uncertain. Therefore, we conducted this study to assess the association of PCI before TAVR with mortality and cardiovascular outcomes. METHODS: We used the TriNetX database (Jan 2012 - Aug 2022) and grouped patients into PCI (3 months or less) before TAVR and no PCI...

BACKGROUND: Studies comparing transcatheter and surgical aortic valve replacement (TAVR and SAVR) for patients with trileaflet aortic stenosis (AS) have found similar or larger effective orifice area (EOA) for TAVR prostheses. To our knowledge, no studies have compared EOA in patients undergoing TAVR versus SAVR for bicuspid AS. METHODS: We retrospectively compared prosthetic valvular sizing and predicted EOA for patients with bicuspid AS undergoing TAVR or SAVR at our institution between January 1, 2016, and December 31, 2021...

Transcatheter heart valve (THV) procedures require careful planning and consideration to prevent coronary artery obstruction (CAO), which poses a significant and potentially life-threatening condition, especially in patients undergoing valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR). Despite identifying predictors of CAO and utilization of computed tomography and inputting THV features, a significant uncertainty remains in predicting CAO. The ShortCut™ device (Pi-Cardia, Rehovot, Israel) was purposefully designed to modify the leaflets in patients undergoing TAVR, especially prior to ViV procedures, to overcome the risk for CAO...

OBJECTIVES: This study evaluated the efficacy of a novel comprehensive shield designed to minimize radiation exposure (RE) to Physicians performing coronary and structural heart procedures. BACKGROUND: The Protego™ radiation shielding system (Image Diagnostics Inc., Fitchburg, Ma) is designed to provide comprehensive protection from RE and has been State certified sufficient to allow operators to perform procedures without orthopedically burdensome lead aprons...

AIM: This study aims to assess the direct impact of bifurcation angle (BA) on immediate procedural outcomes and patient prognosis post-Nano-Crush stenting for coronary bifurcation lesions. METHODS: A retrospective analysis was conducted for all consecutive patients treated with the Nano-Crush technique across two high-volume interventional centers from January 2020 to October 2022. PRIMARY ENDPOINT: comparison of target lesion failure rate in two cohorts based on bifurcation angle (<70° vs...
