The Benefit of Percutaneous Coronary Intervention Before Transcatheter Aortic Valve Replacement: A Multicenter Retrospective Outcome-Based Study.

There is inadequate evidence regarding the role of percutaneous coronary intervention (PCI) in patients who underwent transcatheter aortic valve replacement (TAVR). The current American Heart Association/American College of Cardiology guidelines are limited to class 2A recommendations for pre-TAVR revascularization in the setting of hemodynamically significant left main (LM), proximal left anterior descending (pLAD), or extensive bifurcation disease regardless of angina status. We performed a multicenter, retrospective, observational study assessing the benefit of PCI in patients with coronary artery disease who underwent transfemoral TAVR for severe symptomatic aortic stenosis.

Intermediate Follow-Up of Balloon-Expandable Versus Self-Expanding Transcatheter Aortic Valve Implantation in Patients With Small Aortic Annuli.

The clinical impact of prosthesis-patient mismatch (PPM) in patients with small aortic annuli who underwent transcatheter aortic valve (AV) implantation with either balloon-expandable (BE) or self-expanding (SE) valves remains controversial. We assessed in-hospital and intermediate clinical outcomes in 573 patients with transfemoral transcatheter AV implantation with a small AV annulus, defined as an AV annulus area ≤430 mm. A total of 337 patients treated with a 23-mm BE valve (SAPIEN 3, Ultra) were compared with 236 patients treated with a 26-mm SE valve (Evolut series).

Impact of Ticagrelor Versus Clopidogrel on Bleeding Outcomes of Isolated Coronary Artery Bypass Grafting.

Background: Increased bleeding risks have been documented in patients exposed to P2Y inhibitors within 5 days of coronary artery bypass surgery (CABG). This study aimed to determine the relative CABG bleeding risks of clopidogrel versus ticagrelor exposure and the proper time course of ticagrelor discontinuation prior to surgery.

Methods: Clinical outcomes were assessed in 2075 isolated CABG patients, including 375 who had received P2Y inhibitors within 5 days of surgery (155 clopidogrel, 213 ticagrelor, 7 prasugrel).

The utility of radiographic assessment of the internal mammary arteries in chest wall irradiated patients.

Purpose: The internal mammary arteries (IMA's) are historically recognized to be protected against atherosclerosis. Whether chest wall-irradiation for breast cancer leads to significant IMA damage remains unclear. The utility of computed tomography (CT) and mammography to detect radiation-induced damage to the IMA's and its branches is not known.

Outcomes of Transcatheter Aortic Valve Replacement in Patients Treated With Systemic Steroids.

Background: Chronic steroid therapy is associated with higher vascular complication rates in patients undergoing transcatheter aortic valve replacement (TAVR). The effect of corticosteroids on aortic annular complications has not been directly assessed in this population.

Methods: A retrospective analysis of 1095 patients undergoing transfemoral TAVR was performed.

The impact of asthma on in-hospital outcomes of COVID-19 patients.

Background: The objective of this study is to describe the recent trends and in-hospital outcomes with percutaneous pulmonic valve implantation (PPVI) and surgical pulmonic valve replacement (SPVR) in adult hospitals in the US after the availability of both the Melody valve (Medtronic Inc., Minneapolis, Minnesota) and the Sapien XT valve (Edwards Lifesciences, Irvine, CA).

Methods: We queried the National Inpatient Sample database (NIS) from January 2016 to December 2017 to identify hospitalizations for PPVI and SPVR.

The absence of evidence is not the evidence of absence: A case report on the challenges in diagnosing ostial left main stenosis.

Because left main (LM) coronary artery stenosis is known to have higher mortality and morbidity compared to lesions in other territories, an early diagnosis and management are crucial to prevent worse outcomes. Due to limitations of coronary angiography (CA), the diagnosis of ostial LM stenosis solely based on CA may result in underdiagnosis of such lesions. Therefore, additional testing is often needed either by pressure wire or intravascular ultrasound (IVUS) to make appropriate diagnosis.

Cushing syndrome cardiomyopathy: an unusual manifestation of small-cell lung cancer.

Cushing syndrome is a rare cause of dilated cardiomyopathy and heart failure with reduced ejection fraction. Cases describing this association are scarce. We describe a patient presenting with acute heart failure, new cardiomyopathy, refractory hypokalaemia, severe hyperglycaemia, and uncontrolled hypertension who was found to have hypercortisolism secondary to an ectopic adrenocorticotropic hormone-secreting primary lung neoplasm.

Comparison of Benefit of Transcatheter Aortic Valve Implantation in Patients With Low Gradient Versus High Gradient Aortic Stenosis and Left Ventricular Dysfunction.

Patients with low gradient severe aortic stenosis (LG-AS) often exhibit significant limitations in functional status and quality of life. We aimed to evaluate the clinical effect of transcatheter aortic valve implantation (TAVI) on LG-AS patients compared to those with high transvalvular gradients and similar left ventricular dysfunction. Retrospective analysis of records for all patients with a left ventricular ejection fraction <50% who underwent TAVI at our institution was performed.

NOAC-Based Sual Therapy Versus Warfarin-Based Triple Therapy After Percutaneous Coronary Intervention or Acute Coronary Syndrome in Patients With Atrial Fibrillation: A Systematic Review and Meta-Analysis.

Background: Several randomized clinical trials (RCTs) have compared the use of dual therapy (DT), or one of the non-vitamin K antagonist oral anticoagulants (NOAC) with a P2Y12 agent, versus triple therapy (TT), consisting of a vitamin-K antagonist (VKA) along with dual antiplatelet therapy, in patients with concomitant atrial fibrillation after percutaneous coronary intervention (PCI) or acute coronary syndrome (ACS). We performed a meta-analysis and systematic review of RCTs to evaluate the safety and efficacy of NOAC-based DT in such patients.

Methods: The major efficacy outcome was major adverse cardiovascular and cerebrovascular events (MACCE), defined as a composite of mortality, myocardial infarction, stroke, stent thrombosis (ST), and urgent revascularization.

Evaluation of YouTube as a reliable source for patient education on aortic valve stenosis.

Background: Aortic stenosis (AS) is a prevalent disease in the elderly population and has been a public health concern for decades. YouTube is currently being used for obtaining healthcare related information. We evaluated the quality of information about AS on YouTube for patient education.

Comparative Outcomes of Balloon-Expandable S3 Versus Self-Expanding Evolut Bioprostheses for Transcatheter Aortic Valve Implantation.

To date, comparisons between the balloon-expandable Edwards Sapien S3 (S3) versus the self-expanding Evolut R or PRO (Evolut) valves have been limited with respect to procedural outcomes. We aim to compare the safety, efficacy, and procedural efficiency of the S3 versus the Medtronic Evolut bioprostheses in patients who underwent transcatheter aortic valve implantation for severe aortic stenosis. Retrospective analysis was performed of all consecutive transcatheter aortic valve implantation procedures performed through the transfemoral approach with either S3 or Evolut at our hospital between September 2015 and January 2019.

Background: Previous reports described successful use of transcarotid and transsubclavian approaches for the performance of transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis who cannot be treated with transfemoral access. The purpose of the present study was to compare these two alternative approaches with respect to safety, efficacy, and procedural efficiency.

Methods: A retrospective analysis of all TAVR procedures performed through either a transcarotid or a transsubclavian approach at a single tertiary care medical center between January 2016 and October 2018 was performed.

Propensity Matched Analysis Comparing Conscious Sedation Versus General Anesthesia in Transcatheter Aortic Valve Implantation.

Conscious sedation (CS) has been increasingly utilized in transcatheter aortic valve implantation (TAVI). We aim to compare safety, efficacy, efficiency, and direct cost outcomes of patients who underwent TAVI with general anesthesia (GA) to those with CS. Records for all adult patients undergoing transfemoral TAVI at our institution between February 2012 and September 2018 were retrospectively screened.

Mesalamine-induced Myocarditis in a Young Athlete: Can He Run Again?

Mesalamine is often used in the treatment of inflammatory bowel disease (IBD). Mesalamine-induced cardiotoxicity has been reported in the literature and is a rare entity. The mechanism of cardiotoxicity remains unclear, however, it is believed to be due to a humoral-mediated hypersensitivity reaction.

Elevated end-diastolic wall stress after acute myocardial infarction predicts adverse cardiovascular outcomes and longer hospital length of stay.

Background: Acute myocardial infarction (MI) leads to ventricular remodeling in response to oxygen demand. Such changes include left ventricular (LV) dilatation and increased myocardial wall stress. Prior studies showed that wall stress is a vital parameter of cardiac remodeling.

A Partial Anomalous Pulmonary Venous Connection in a Severely Symptomatic Patient, Is Surgery Always Recommended?

Partial anomalous pulmonary venous connection (PAPVC) is a rare cardiac anomaly occurring when a pulmonary vein drains into the right atrium, coronary sinus or a systemic vein creating a left-to-right shunt. Symptoms develop from right-sided fluid overload and pulmonary vascular disease. We report a rare case of a severely symptomatic patient with an incidentally discovered PAPVC in the setting of underlying severe pulmonary hypertension from multifactorial severe restrictive lung disease.

Automation, machine learning, and artificial intelligence in echocardiography: A brave new world.

Automation, machine learning, and artificial intelligence (AI) are changing the landscape of echocardiography providing complimentary tools to physicians to enhance patient care. Multiple vendor software programs have incorporated automation to improve accuracy and efficiency of manual tracings. Automation with longitudinal strain and 3D echocardiography has shown great accuracy and reproducibility allowing the incorporation of these techniques into daily workflow.

The Therapeutic Potential of Blocking Galectin-3 Expression in Acute Myocardial Infarction and Mitigating Inflammation of Infarct Region: A Clinical Outcome-Based Translational Study.

Introduction: Increased galectin-3 is associated with ischemic cardiomyopathy, although its role in early remodeling post-myocardial infarction (MI) has not been fully elucidated. There are no data demonstrating that blocking galectin-3 expression would have an impact on the heart and that its relationship to remodeling is not simply an epiphenomenon. The direct association between galectin-3 and myocardial inflammation, dysfunction, and adverse cardiovascular outcomes post-MI was examined using clinical and translational studies.

The use of cardiac-CT alone to exclude left atrial thrombus before atrial fibrillation ablation: Efficiency, safety, and cost analysis.

Background: Atrial fibrillation (AF) is a growing financial burden on the healthcare system. Cardiac computed tomographic angiography (CCTA) is needed for pulmonary vein mapping before AF ablation (AFA). CCTA has shown to be an alternative to transesophageal echocardiogram (TEE) to rule out left atrial appendage thrombus (LAAT) pre-AFA.
