Transcatheter Repair of Tricuspid Valve Regurgitation: A Systematic Review.

Clinically significant severe tricuspid regurgitation (TR) is a common untreated pathology associated with increased mortality. Even though surgical valve replacement has been the mainstay option, transcatheter intervention is a novel and potentially effective tool. To the best of our knowledge, this is the first systematic review that assessed and compared clinical and echocardiographic outcomes of coaptation and annuloplasty devices in patients with clinically significant TR.

Cerebral embolic protection for stroke prevention during transcatheter aortic valve replacement.

Introduction: Cerebral Embolic Protection Device (CEPD) captures emboli during Transcatheter Aortic Valve Replacement (TAVR). With recently published pivotal trials and multiple cohort studies reporting new data, there is a need to re-calibrate available statistical evidence.

Methods: A systematic literature search was conducted across databases from inception till February 2023.

Atrial Fibrillation Ablation-induced Pulmonary Venous Occlusion Requiring Pneumonectomy.

A 71-year-old woman with a history of atrial fibrillation underwent a catheter-based ablation procedure. Months later, she presented with dyspnea and a left-sided pleural effusion. Diagnostic evaluation revealed left-sided pulmonary venous occlusion, with essentially absent left lung perfusion.

Early Usage of Extracorporeal Membrane Oxygenation in the Absence of Invasive Mechanical Ventilation to Treat COVID-19-related Hypoxemic Respiratory Failure.

A subset of patients with coronavirus disease 2019 (COVID-19) develop profound respiratory failure and are treated via invasive mechanical ventilation (IMV). Of these, a smaller subset has severe gas exchange abnormalities that are refractory to maximal levels of IMV support. Extracorporeal membrane oxygenation (ECMO) has been used successfully in these circumstances.

Trans-ventricular catheter device-based closure of postmyocardial infarction ventricular septal defect following coronary artery bypass grafting: A staged hybrid approach.

A 66-year-old woman with a history of hypertension, ischemic stroke, and rheumatoid arthritis presented to the hospital with severe angina pectoris and dyspnea and was diagnosed with myocardial infarction (MI). Coronary angiography revealed multisystem coronary artery occlusive disease. Due to refractory myocardial ischemia/evolving MI, emergency coronary artery bypass grafting (CABG) was undertaken.

Clinically Important Misclassification of Aortic Valve Stenosis Severity Using Non-Invasive Techniques: Simultaneous Echocardiography and Cardiac Catheterization During Transcatheter Aortic Valve Implantation in Awake Patients.

Background: Suitability for transcatheter aortic valve (AV) implantation (TAVI) is determined by using transthoracic echocardiography (TTE), although left-sided cardiac catheterization (LCC) provides directly measured pressure data. TAVI in awake patients permits simultaneous comparison of TTE and LCC under physiologically relevant left ventricular loading conditions. We hypothesized that clinically important discrepancies between TTE and LCC would be identified.

Advanced Pulmonary and Cardiac Support of COVID-19 Patients: Emerging Recommendations From ASAIO-A "Living Working Document".

The severe acute respiratory syndrome (SARS)-CoV-2 is an emerging viral pathogen responsible for the global coronavirus disease 2019 (COVID)-19 pandemic resulting in significant human morbidity and mortality. Based on preliminary clinical reports, hypoxic respiratory failure complicated by acute respiratory distress syndrome is the leading cause of death. Further, septic shock, late-onset cardiac dysfunction, and multiorgan system failure are also described as contributors to overall mortality.

Direct Transcatheter Valve Deployment via Sternotomy for Complex Aortic Valve Reoperation.

Reoperative aortic valve replacement is associated with increased morbidity. Valve-in-valve transcatheter aortic valve replacement offers a less invasive alternative to traditional reoperation. However, cases of valve failure after valve-in-valve transcatheter aortic valve replacement represent a complex surgical challenge.

Balloon-expandable transcatheter aortic valve replacement outcomes by procedure location: Catheterization laboratory versus operating room.

Background: The impact of procedure location on clinical outcomes after TAVR remains unclear. We aimed to compare short-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) in the catheterization laboratory (CATH) versus surgical operating room (OR).

Methods: A retrospective review of 63,581 trans-femoral TAVR patients using balloon-expandable valves from 2015 to 2018 were captured utilizing the TVT Registry.

Bioprosthetic valve fracture: Technical insights from a multicenter study.

Objective: Valve-in-valve transcatheter aortic valve replacement (VIV TAVR) can result in high residual gradients that are associated with increased mortality. Bioprosthetic valve fracture (BVF) has been shown to improve residual gradients following VIV TAVR; however, factors influencing the results of BVF have not been studied.

Methods: BVF was performed in 75 patients at 21 centers.

Regional, Artery-Specific Thresholds of Quantitative Myocardial Perfusion by PET Associated with Reduced Myocardial Infarction and Death After Revascularization in Stable Coronary Artery Disease.

Because randomized coronary revascularization trials in stable coronary artery disease (CAD) have shown no reduced myocardial infarction (MI) or mortality, the threshold of quantitative myocardial perfusion severity was analyzed for association with reduced death, MI, or stroke after revascularization within 90 d after PET. In a prospective long-term cohort of stable CAD, regional, artery-specific, quantitative myocardial perfusion by PET, coronary revascularization within 90 d after PET, and all-cause death, MI, and stroke (DMS) at 9-y follow-up (mean ± SD, 3.0 ± 2.

Surgical pulmonary embolectomy and catheter-based therapies for acute pulmonary embolism: A contemporary systematic review.

Objectives: Mortality in acute pulmonary embolism (PE) is believed to be principally due to the subgroup of PEs that are massive. Systemic thrombolysis is the therapeutic mainstay for acute massive PE, despite evidence suggesting limited survival benefits. Both catheter-based therapies (CBT) and surgical pulmonary embolectomy (SE) are well-accepted alternatives to treat acute PE.

Cardiac sarcoidosis presenting as arrhythmogenic right ventricular cardiomyopathy/dysplasia with ventricular aneurysms: a case report.

A 70-year old Caucasian man with recurrent ventricular tachycardia and progressive biventricular failure attributed to arrhythmogenic right ventricular cardiomyopathy/dysplasia was evaluated for heart transplantation. Cardiac ventriculography revealed an abnormal left ventricle with five saccular aneurysms. Heart transplantation was performed.

"Bringing on the light" in a complex clinical scenario: Optical coherence tomography-guided discontinuation of antiplatelet therapy in cancer patients with coronary artery disease (PROTECT-OCT registry).

Background: Cancer patients with recently placed drug-eluting stents (DESs) often require premature dual antiplatelet therapy (DAPT) discontinuation for cancer-related procedures. Optical coherence tomography (OCT) can identify risk factors for stent thrombosis such as stent malapposition, incomplete strut coverage and in-stent restenosis and may help guide discontinuation of DAPT.

Methods: We conducted a single-center prospective study in cancer patients with recently placed (1-12 months) DES who required premature DAPT discontinuation.

Valve-in-Valve Transcatheter Aortic Valve Implantation: A Novel Approach to Treat Paravalvular Leak.

Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure.

Intra-Pericardial Use of Recombinant Factor VIIa in a Patient With Acute Hemorrhagic Pericardial Effusion Following Transcutaneous Aortic Valve Replacement-A Case Report.

Perioperative bleeding can be a serious life-threatening complication in adult patients undergoing cardiac surgery, given the older age and additional comorbidities present in this patient population. The standard treatment options include transfusion of blood components and surgical re-exploration. We report the first case of an elderly female patient treated with local administration of recombinant factor VIIa (rFVIIa) for intractable hemorrhagic pericardial effusion, which developed following a transcutaneous aortic valve replacement (TAVR) procedure for severe aortic stenosis.
