Nationwide trends of balloon pulmonary angioplasty and pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension (2012-2019).

Chronic thromboembolic pulmonary hypertension (CTEPH) is a sequela of a pulmonary embolus that occurs in approximately 1%-3% of patients. Pulmonary thromboendoarterectomy (PTE) can be a curative procedure, but balloon pulmonary angioplasty (BPA) has emerged as an option for poor surgical candidates. We used the National Inpatient Sample to query patients who underwent PTE or BPA between 2012 and 2019 with CTEPH.

Patent Foramen Ovale Closure in Older Patients With Stroke: Patient Selection for Trial Feasibility.

Background And Objectives: Whether patent foramen ovale (PFO) closure benefits older patients with PFO and cryptogenic stroke is unknown because randomized controlled trials (RCTs) have predominantly enrolled patients younger than 60 years of age. Our objective was to estimate anticipated effects of PFO closure in older patients to predict the numbers needed to plan an RCT.

Methods: Effectiveness estimates are derived from major observational studies (Risk of Paradoxical Embolism [RoPE] Study and Oxford Vascular Study, together referred to as the "RoPE-Ox" database) and all 6 major RCTs (Systematic, Collaborative, PFO Closure Evaluation [SCOPE] Consortium).

Feasibility and Safety of Impella-Assisted High-Risk PCI Before TAVR in Patients With Severe Aortic Stenosis.

Background: There are limited data on the feasibility of Impella-assisted percutaneous coronary intervention (PCI) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR).

Methods: To assess the feasibility of the Impella-assisted PCI in patients with severe symptomatic AS, we retrospectively reviewed the medical records to identify patients who were electively admitted for Impella-assisted PCI with a subsequent TAVR at Weill Cornell Medical Center from 2016 to 2021.

Results: During the study period, 15 patients were identified to be eligible for the study, but the Impella failed to cross the aortic valve in 1 patient despite a concomitant balloon aortic valvuloplasty requiring a switch to an intra-aortic balloon pump to assist PCI.

SCAI/HRS expert consensus statement on transcatheter left atrial appendage closure.

Exclusion of the left atrial appendage to reduce thromboembolic risk related to atrial fibrillation was first performed surgically in 1949. Over the past 2 decades, the field of transcatheter endovascular left atrial appendage closure (LAAC) has rapidly expanded, with a myriad of devices approved or in clinical development. The number of LAAC procedures performed in the United States and worldwide has increased exponentially since the Food and Drug Administration approval of the WATCHMAN (Boston Scientific) device in 2015.

Transcatheter Left Ventricular Restoration in Patients With Heart Failure.

Background: Left ventricular (LV) volume reshaping reduces myocardial wall stress and may induce reverse remodeling in patients with heart failure with reduced ejection fraction. The AccuCinch Transcatheter Left Ventricular Restoration system consists of a series of anchors connected by a cable implanted along the LV base that is cinched to the basal free wall radius. We evaluated the echocardiographic and clinical outcomes following transcatheter left ventricular restoration.

Association of Atrial Septal Aneurysm and Shunt Size With Stroke Recurrence and Benefit From Patent Foramen Ovale Closure.

Importance: The Patent Foramen Ovale (PFO)-Associated Stroke Causal Likelihood classification system combines information regarding noncardiac patient features (vascular risk factors, infarct topography) and PFO features (shunt size and presence of atrial septal aneurysm [ASA]) to classify patients into 3 validated categories of responsiveness to treatment with PFO closure. However, the distinctive associations of shunt size and ASA, alone and in combination, have not been completely delineated.

Objective: To evaluate the association of PFO closure with stroke recurrence according to shunt size and/or the presence of an ASA.

Racial Disparities in Access to High-Volume Mitral Valve Transcatheter Edge-to-Edge Repair Centers.

Background: Severe mitral regurgitation is a progressive disease associated with high morbidity and mortality, and frequent readmissions for heart failure. Surgical mitral valve repair or replacement has been the gold-standard treatment; however, advances in transcatheter edge-to-edge repair (TEER) have provided alternatives for high-risk surgical patients. There are no data on racial disparities in access to high-volume TEER centers.

Treatment of severe acute mitral regurgitation following thoracoabdominal aortic aneurysm repair.

An asymptomatic 63-year-old male with chronic type B aortic dissection underwent repair of an expanding 6.1 cm extent I thoracoabdominal aortic aneurysm. His postoperative course was complicated by respiratory failure from severe acute mitral regurgitation likely due to papillary muscle rupture, which was corrected with transcatheter MitraClip edge-to-edge repair.

Best Practice Recommendations for Optimizing Care in Structural Heart Programs: Planning Efficient and Resource Leveraging Systems (PEARLS).

The COVID19 pandemic brought unprecedented disruption to healthcare. Staggering morbidity, mortality, and economic losses prompted the review and refinement of care for structural heart disease (SHD). To mitigate negative impacts in the face of crisis or capacity constraints, this paper offers best practice recommendations for Planning Efficient and Resource Leveraging Systems (PEARLS) in structural heart programs.

Impact of inferior vena cava entry characteristics on tricuspid annular access during transcatheter interventions.

Objectives: The purpose of this study was to characterize the anatomic relationship between the inferior vena cava (IVC) and tricuspid annulus (TA) and its potential impact on the performance of transcatheter TV interventions.

Background: Transcatheter tricuspid valve (TV) interventions are emerging as a therapeutic alternative for the treatment of severe, symptomatic tricuspid regurgitation (TR). Progression of TR is associated with right heart dilatation.

The impact of pulmonary hypertension on outcomes of transcatheter mitral valve replacement in mitral annular calcification.

Objectives: To assess the impact of pulmonary hypertension (PH) on outcomes of patients with severe mitral annular calcification (MAC) undergoing transcatheter mitral valve replacement (TMVR).

Background: PH is associated with poor outcomes after mitral valve surgery. Whether the presence of PH in patients with MAC undergoing (TMVR) is associated with poor outcomes, is unknown.

Heterogeneity of Treatment Effects in an Analysis of Pooled Individual Patient Data From Randomized Trials of Device Closure of Patent Foramen Ovale After Stroke.

Importance: Patent foramen ovale (PFO)-associated strokes comprise approximately 10% of ischemic strokes in adults aged 18 to 60 years. While device closure decreases stroke recurrence risk overall, the best treatment for any individual is often unclear.

Objective: To evaluate heterogeneity of treatment effect of PFO closure on stroke recurrence based on previously developed scoring systems.

Relative Impact of Surgical Mitral Repair and MitraClip on Annular Remodeling-A Potential Mechanism for Therapeutic Response to Mitral Repair for Degenerative Mitral Regurgitation.

Objectives: Three-dimensional transesophageal echocardiography (TEE) is widely used to guide decision-making for mitral repair. The relative impact of surgical mitral valve repair (MVr) and MitraClip on annular remodeling is unknown. The aim was to determine the impact of both mitral repair strategies on annular geometry, including the primary outcome of annular circumference and area.

Functional Connectivity of the Developing Mouse Cortex.

Cross-sectional studies have established a variety of structural, synaptic, and cell physiological changes corresponding to critical periods in cortical development. However, the emergence of functional connectivity (FC) in development has not been fully characterized, and hemodynamic-based measures are vulnerable to any neurovascular coupling changes occurring in parallel. We therefore used optical fluorescence imaging to trace longitudinal calcium FC in the awake, resting-state mouse cortex at 5 developmental timepoints beginning at postnatal day 15 (P15) and ending in early adulthood at P60.
