Most hospitalized patients with significant tricuspid regurgitation have advanced disease preventing transcatheter tricuspid valve intervention.

Background: More than moderate tricuspid regurgitation (TR) is associated with high mortality. Surgical tricuspid valve repair and replacements are rarely performed due to high operative mortality risk, mainly attributed to late presentation. Novel transcatheter tricuspid valve intervention (TTVI) devices are being developed as an alternative to surgery.

Referral for Cardiac Amyloidosis in Patients Who Underwent Transcatheter Aortic Valve Replacement: Results of the Quality Outcome Project.

Background Transthyretin cardiac amyloidosis (ATTR) is an important comorbidity present in severe aortic stenosis (AS). The purpose of this study was to raise awareness of ATTR in patients who underwent transcatheter aortic valve replacement (TAVR) for severe AS among healthcare providers and patients. Methodology We reviewed 197 consecutive TAVR cases performed from 2019 to 2020.

Association of Migraine Headache With Depression, Anxiety, and Stress in the Population of Makkah City, Saudi Arabia: A Cross-Sectional Study.

Introduction Migraine is characterized by persistent headaches and a wide range of symptoms, such as nausea, vomiting, and photophobia. The chance of developing a chronic migraine might be increased by lifestyle variables like obesity, stress, and excessive medication use. According to previous studies in Saudi Arabia, migraines are more common there than they are globally.

Comparison of American and European Guidelines for the Management of Patients With Valvular Heart Disease.

This review compares the recommendations of the recent 2020 American College of Cardiology (ACC)/American Heart Association (AHA) and 2021 European Society of Cardiology (ESC)/European Association for Cardio-Thoracic Surgery (EACTS) guidelines on the management of patients with valvular heart disease (VHD). ACC/AHA and ESC/EACTS guidelines are both the updated versions of previous 2017 documents. Both guidelines fundamentally agree on the extended indications of percutaneous valve interventions, the optimal use of imaging modalities other than 2D echocardiography, the importance of a multidisciplinary Heart Team as well as active patient participation in clinical decision making, more widespread use of NOACs and earlier intervention with lower left ventricular dilatation thresholds to decrease long-term mortality.

Implementation of 3D Printing in Medical Care for Preoperative Planning of Complex Ventricular Septal Defect.

Three-dimensional (3D) modeling and printing in medicine have emerged to encompass every aspect of medical applications. This ranges from education, illustration, and treatment, as well as patient care whether for purposes of diagnosis or treatment and surgical planning. In the past few decades, these novel tools have shown promising utility to help radiologists and the medical team to improve quality of patient care and outcomes via 3D printing application and utilization.

2021. The year in review. Structural heart interventions.

Since the beginning of 2020, the corona virus (COVID-19) pandemic redefined in many ways the practice of cardiology, research and cardiology conferences. Virtual conferences replaced most major in-person venues. The number of "elective" structural heart interventions declined and clinical research endured major setbacks in regards to academic and industry-sponsored clinical trials.

Three-dimensional cardiac print assisted percutaneous closure of left ventricular pseudoaneurysm in patient with Behçet's disease.

Spontaneous left ventricular pseudoaneurysms are very rare and can have catastrophic consequences if unrecognized. A case of combined spontaneous left ventricular aneurysm and pseudoaneurysm in Behcet's disease (BD) has been reported. The case emphasizes advanced techniques for percutaneous closure of the defects with the use of an ex-vivo three-dimensional cardiac printed model as a tool to facilitate the procedure.

Management of Iatrogenic Atrial Septal Defects in the Era of Large-Bore Transcatheter Mitral Valve Therapies.

Several case reports described acute and subacute decompensations that were reversed after percutaneous interatrial septal defect (ASD) closure. At least 30% of patients post MitraClip will continue to have a persistent ASD at 1 year. Few retrospective studies described various echocardiographic associations with persistent ASD but there is no conclusive evidence that it is the cause of a poor outcome.

eXaSkin: A novel high-density bolus for 6MV X-rays radiotherapy.

Purpose: To evaluate eXaSkin, a novel high-density bolus alternative to commercial tissue-equivalent Superflab, for 6MV photon-beam radiotherapy.

Materials And Methods: We delivered a 10 × 10 cm open field at 90° and head-and-neck clinical plan, generated with the volumetric modulated arc therapy (VMAT) technique, to an anthropomorphic phantom in three scenarios: with no bolus on the phantom's surface, with Superflab, and with eXaSkin. In each scenario, we measured dose to a central planning target volume (PTV) in the nasopharynx region with an ionization chamber, and we measured dose to the skin, at three different positions within the vicinity of a neck lymph node PTV, with MOSkin™, a semiconductor dosimeter.

Quality assurance of VMAT on flattened and flattening filter-free accelerators using a high spatial resolution detector.

Purpose: This study investigated the use of high spatial resolution solid-state detectors (DUO and Octa) combined with an inclinometer for machine-based quality assurance (QA) of Volumetric Modulated Arc Therapy (VMAT) with flattened and flattening filter-free beams.

Method: The proposed system was inserted in the accessory tray of the gantry head of a Varian 21iX Clinac and a Truebeam linear accelerator. Mutual dependence of the dose rate (DR) and gantry speed (GS) was assessed using the standard Varian customer acceptance plan (CAP).

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.

Infection with the Lyme disease pathogen suppresses innate immunity in mice with diet-induced obesity.

Obesity is a major global public health concern. Immune responses implicated in obesity also control certain infections. We investigated the effects of high-fat diet-induced obesity (DIO) on infection with the Lyme disease bacterium Borrelia burgdorferi in mice.

When should fractional flow reserve be performed to assess the significance of borderline coronary artery lesions: Derivation of a simplified scoring system.

Objectives: To derive a simplified scoring system (SSS) that can assist in selecting patients who would benefit from the application of fractional flow reserve (FFR).

Background: Angiographers base decisions to perform FFR on their interpretation of % diameter stenosis (DS), which is subject to variability. Recent studies have shown that the amount of myocardium at jeopardy is an important factor in determining the degree of hemodynamic compromise.

Combined coagulation-flocculation and sequencing batch reactor with phosphorus adjustment for the treatment of high-strength landfill leachate: experimental kinetics and chemical oxygen demand fractionation.

Unlabelled: The treatability of high-strength landfill leachate is challenging and relatively limited. This study examines the feasibility of treating high-strength landfill leachate (chemical oxygen demand [COD]: 7,760-11,770 mg/L, biochemical oxygen demand [BOD5]: 2,760-3,569 mg/L, total nitrogen [TN] = 980-1,160 mg/L) using a sequencing batch reactor (SBR) preceded by a coagulation-flocculation process with phosphorus nutritional balance under various mixing and aeration patterns. Simulations were also conducted to define kinetic parameters and COD fractionation.

The management of thrombotic lesions in the cardiac catheterization laboratory.

Plaque rupture with superimposed thrombosis is the major mechanism of acute coronary syndromes. Although angiography underestimates the presence of thrombi, their detection is a poor prognostic indicator which is proportional to their size. Although emergent percutaneous coronary intervention (PCI) in the setting of ST elevation myocardial infarction (STEMI) and early PCI in the setting of unstable angina and non-STEMI were shown to be preferred strategies, the presence of angiographic thrombosis by virtue of causing micro and macro embolization can reduce the benefit of the intervention.

Renal dysfunction in heart failure is due to congestion but not low output.

Background: Renal dysfunction in heart failure is thought to be due to poor perfusion of the kidney.

Hypothesis: We tested the hypothesis that passive congestion is more important than poor perfusion.

Methods: We retrospectively studied the data on 178 patients who underwent right heart catheterization for evaluation of heart failure and had serum creatinine (Cr) measured on the same day.

Limitations of embolic protection in saphenous vein graft intervention: insights from 202 consecutive patients.

Between January 2003 and September 2006, a total of 2,541 patients had percutaneous coronary intervention (PCI). Of these, 202 (226 grafts) had at least one saphenous vein graft (SVG) intervention. Adjunctive distal embolic protection (DEP) devices were attempted in 123 SVGs (54.

Structure/function relationships in dyes for solar energy conversion: a two-atom change in dye structure and the mechanism for its effect on cell voltage.

Recombination between injected electrons and iodine limits the photovoltage in dye-sensitized solar cells (DSSCs). We have recently suggested that many new dye molecules, intended to improve DSSCs, can accelerate this reaction, negating the expected improvement (J. Am.
