Cardiovascular Revascularization Medicine : Including Molecular Interventions

Coronary artery bypass (CABG) has evolved over the decades, supported by scientific evidence from robust studies. The downgrade of the recommendation for CABG in patients with multivessel coronary artery disease proposed by the 2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization and the 2023 ACC/AHA Chronic Coronary Disease Guidelines has brought this discussion to the fore, with prestigious cardiothoracic surgery societies such as AATS and STS not supporting these recommendations. The purpose of this article is to broaden this discussion in light of published studies...

BACKGROUND/OBJECTIVES: Recent trends indicate a rise in the incidence of critical limb ischemia (CLI) among younger adults. This study examines trends in CLI hospitalization and outcomes among young adults with peripheral arterial disease (PAD) in the United States. METHODS: Adult hospitalizations (18-40 years) for PAD/CLI were analyzed from the 2016-2020 nationwide inpatient sample database using ICD-10 codes. Rates were reported per 1000 PAD or 100,000 cardiovascular disease admissions...

BACKGROUND: Catheter-based renal sympathetic denervation (RDN) reduced blood pressure (BP) in multiple randomized sham-controlled trials of patients with uncontrolled hypertension (HTN). We tested proof-of-concept for a more selective treatment strategy, exclusively targeting these areas to improve the efficiency of the procedure. METHODS: The SPYRAL DYSTAL Pilot study was designed to mirror the SPYRAL HTN-OFF MED Pivotal study, enabling comparison with a propensity score adjusted active-control group...

BACKGROUND: The next generation supra-annular, self-expanding Evolut FX transcatheter aortic valve (TAV) system was designed to improve catheter deliverability, provide stable and symmetric valve deployment, and assess commissural alignment during the procedure. The impact of these modifications has not been clinically evaluated. METHODS: Procedural information was collected by survey in 2 Stages: Stage I comprised 23 centers with extensive experience with Evolut TAV systems, and Stage II comprised an additional 46 centers with a broad range of balloon- and self-expanding system experience...

BACKGROUND: The impact of new-onset left bundle branch block (N-LBBB) developing after Transcatheter Aortic Valve Replacement (TAVR) on cardiac function and mechanical dyssynchrony is not well defined. METHODS: We retrospectively screened all patients who underwent TAVR in our centre between Oct 2018 and Sept 2021 (n = 409). We identified 38 patients with N-LBBB post-operatively (of which 28 were persistent and 10 were transient), and 17 patients with chronic pre-existent LBBB (C-LBBB)...

INTRODUCTION: Pacemaker (PPM) implantation is indicated for conduction abnormalities which can develop post-transcatheter aortic valve replacement (TAVR). However, whether post-TAVR PPM risk is associated with the geographical location of the hospital and socioeconomic status of the patient is not well established. Our goal was to explore geographical and socioeconomic disparities in post-TAVR PPM implantation. METHODS: A retrospective cohort analysis was conducted using the National Inpatient Sample 2016-2020 with respective ICD-10 codes for TAVR and PPM implantation...

INTRODUCTION: In patients undergoing transcatheter aortic valve replacement (TAVR), cerebral embolic protection devices (CEPD) are used to possibly diminish the risk of periprocedural stroke. Trends and outcomes of CEPD usage in TAVR are not well characterized. METHODS: National readmission databases (NRD) 2017-2019 was used to identify hospital admissions for TAVR using ICD-10 codes, with versus without Sentinel CEPD. Primary outcomes of the study were in-hospital and 30-day stroke...

BACKGROUND: In the 2021 Transcatheter Valve Therapy (TVT) registry, 8.9 % of patients underwent TAVR via access sites other than the femoral artery. Transthoracic approaches may be contraindicated in some patients and may be associated with poorer outcomes. Therefore other alternative access routes are increasingly being performed. We conducted a systematic review of the literature on transcarotid transcatheter aortic valve replacement (TC-TAVR) and meta-analysis comparing outcomes of TC-TAVR and other access routes...

BACKGROUND: The outcomes after mitral valve transcatheter edge-to-edge repair (M-TEER) for the patients with severe mitral regurgitation (MR) in hemodynamically unstable conditions, such as cardiogenic shock, still remain unclear. We aimed to integrate previous publications regarding M-TEER indicated for life-threatening conditions and indirectly particularly compared the short-term outcomes thereof, with that of other treatments. METHODS: We systematically searched the PubMed, Cochrane, and MEDLINE databases for studies from inception to June 2023, regarding M-TEER in patients with hemodynamic instability and severe MR...

INTRODUCTION: Despite the growing adoption of transcatheter aortic valve replacement (TAVR), there remains a lack of clinical data evaluating procedural safety and discharge practices. AIMS: This study aims to investigate if there have been improvements in postoperative clinical outcomes following TAVR. METHODS: In this large-scale, retrospective cohort study, patients who underwent TAVR as an inpatient were identified from 2016 to 2020 using the National Readmissions Database...

BACKGROUND: Patients with dementia are at increased risk for adverse events following valvular surgery. Outcomes after mitral transcatheter edge-to-edge repair (TEER) for mitral regurgitation in this vulnerable population are not well understood. METHODS: We queried the National Inpatient Sample database for all hospitalizations for mitral TEER between 2016 and 2019. Patients with a validated diagnosis code for dementia were identified by ICD-10 codes and compared to a matched cohort of non-dementia patients using multivariable regression analysis...

BACKGROUND/PURPOSE: Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) increases morbidity and mortality. Our study aimed to investigate the role of baseline N-terminal pro B-type natriuretic peptide (NT-proBNP) as a predictor of AKI following TAVI. METHODS: All consecutive TAVI patients were included in the analysis, except patients with dialysis and those with a GFR < 15 ml/min/1.73 m2 at baseline. Rates of AKI after TAVI were assessed according to the updated valve academic research consortium definitions using AKIN classification in three stages...

BACKGROUND: Atrial fibrillation (AF) and pericardial effusion are notable complications following coronary artery bypass grafting (CABG), contributing to increased morbidity and healthcare costs. Posterior pericardiotomy has been proposed to mitigate these complications. This systematic review and meta-analysis aim to evaluate the efficacy of posterior pericardiotomy in reducing postoperative AF and pericardial effusion in isolated CABG patients. MATERIALS AND METHODS: A comprehensive literature search, adhering to PRISMA guidelines, was conducted across PubMed, MEDLINE via Ovid, Embase, Scopus, the Central Register of Controlled Trials (CENTRAL), and ClinicalTrials...

PURPOSE: The aim of this study was to determine if postprocedural peripheral fractional flow reserve (pFFR) is associated with patency one year after drug-coated balloon (DCB) angioplasty for femoropopliteal (FP) lesions. MATERIALS AND METHODS: Forty-five consecutive patients having 49 de novo FP lesions were enrolled in this prospective, observational study conducted from April 2022 to Aug 2023. The pFFR was measured under hyperemic conditions after the administration of 30 mg of papaverine...

BACKGROUND: Candidates for transcatheter aortic valve replacement (TAVR) occasionally have a "borderline-size" aortic annulus between 2 transcatheter heart valve sizes, based on the manufacturer's sizing chart. Data on TAVR outcomes in such patients are limited. METHODS: We retrospectively reviewed 1816 patients who underwent transfemoral-TAVR with balloon-expandable valve (BEV) at our institution between 2016 and 2020. We divided patients into borderline and non-borderline groups based on computed tomography-derived annular measurements and compared outcomes...
