EDITORIAL
Dhaval R Parekh, Zvonimir Krajcer
Recurrent coarctation postoperative Norwood is poorly tolerated in single ventricle patients. Although transcatheter balloon angioplasty is considered first line, it often leads to inadequate or non-durable relief of obstruction. Transcatheter stent implantation provides excellent relief of obstruction but necessitates staged redilation to account for somatic growth in children. Stent technology, delivery systems, and procedural techniques will need to evolve to obviate reported adverse events mainly due to patient size...

OBJECTIVE: Trans-catheter (TC) pulmonary valve replacement (PVR) has become common practice for patients with right ventricular outflow tract obstruction (RVOTO) and/or pulmonic insufficiency (PI). Our aim was to compare PVR and right ventricular (RV) function of patients who received TC vs surgical PVR. DESIGN: Retrospective review of echocardiograms obtained at three time points: before, immediately after PVR, and most recent. PATIENTS: Sixty-two patients (median age 19 years, median follow-up 25 months) following TC (N = 32) or surgical (N = 30) PVR at Yale-New Haven Hospital were included...

Chronic oral anticoagulation therapy is the standard therapy for preventing thromboembolic events in patients with atrial fibrillation. However, oral anticoagulation has been associated with an increased risk of bleeding events, and despite the improvements linked to the introduction of direct oral anticoagulants, more than one third of atrial fibrillation patients still remain untreated. Over the past decade, percutaneous left atrial appendage closure has emerged as a valid alternative to anticoagulation therapy for the prevention of stroke/systemic embolism in patients with atrial fibrillation...

OBJECTIVE: It is intuitive to suggest that knowledge of the variation in the anatomy of the aortic root may influence the outcomes of transcatheter implantation of the aortic valve (TAVI). We have now assessed such variation. METHODS: We used 26 specimens of normal hearts and 78 CT data sets of adults with a mean age of 64±15 years to measure the dimensions of the membranous septum and to assess any influence played by rotation of the aortic root, inferring the relationship to the atrioventricular conduction axis...

BACKGROUND: Acute Kidney Injury (AKI) is a frequent complication after a Transcatheter Aortic Valve Implantation (TAVI). Biomarkers such as urinary G1 cell cycle arrest proteins (TIMP-2 and IGFBP7) and sonographic evaluation (Doppler Renal Resistive Index (RRI)) have been advocated to predict AKI at an early stage after a TAVI-procedure. The primary aim was to determine the predictive value of these markers to detect AKI after a TAVI-procedure at an early phase. PATIENTS AND METHODS: In a prospective observational study, 62 consecutive patients were scheduled for a TAVI...

Transcatheter prosthetic valves are heralding a new era in interventional cardiology and affording real therapeutic options to categories of patients currently medically disqualified, namely the elderly and higher risk individuals. An increasing variety of novel artificial valve designs and delivery systems are being tested preclinically. Cardiologists and surgeons are generally well-equipped to assess deliverability and function; however, methods for pathological evaluation of animals enrolled in transcatheter valve implant testing are scant, often vague, and far from consensual...

RATIONALE: The occurrence of bleeding and hematoma from bone metastasis of hepatocellular carcinoma (HCC) is extremely rare. PATIENT CONCERNS: We present a case of scapular metastasis of HCC in a 69-year-old man who presented with acute bleeding and hematoma. DIAGNOSES: Chest computed tomography showed a large hematoma within the right pectoral muscle of the right upper chest and an exophytic metastatic mass in the right scapula with bony destruction, which caused the intramuscular hematoma...

OBJECTIVE: To evaluate the feasibility, safety, and efficacy of a novel Cocoon Duct Occluder device for the transcatheter closure (TCC) of large patent ductus arteriosus (PDA). METHODS: In this prospective, non-randomized study, consecutive patients with large PDA (narrowest diameter: ≥3.5/4.0 mm in symptomatic/asymptomatic patients, respectively), who underwent TCC with Cocoon Duct Occluder at our institute between November, 2012 and June, 2016 were examined...

PURPOSE: To determine the time point at which thrombocytopenia after TAVI procedure is an indicator of the worst prognosis, with special consideration of perioperative platelet and coagulation activation as its potential causes. METHODS: Thirty two patients (mean age 78.5±7.9years, 62% females) qualified for TAVI procedure were prospectively evaluated. Platelet counts were assessed at baseline and for the next three postoperative (POD) days. Platelet activation was evaluated by P-selectin (PS, serum, ELISA) and platelet factor 4 (PF-4, CTAD plasma), and blood coagulation activation by prothrombin fragments 1+2 (F1+2, plasma, ELISA)...

Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

Pulmonary arteriovenous malformations (PAVMs) are atypical vascular structures involving a direct connection between the pulmonary arterial and venous circulations. While PAVMs are a relatively uncommon disorder, unmanaged cases are at risk for the development of serious complications including embolization and infection. Since their first description in 1897, PAVMs have been identified and treated in a variety of ways. Advancements in diagnostic methods and operative techniques have allowed for more effective treatment of the disease...

Background -In non-randomized, open-label studies, a transcatheter interatrial shunt device (IASD, Corvia Medical) was associated with lower pulmonary capillary wedge pressure (PCWP), less symptoms, and greater quality of life and exercise capacity in patients with heart failure (HF) and mid-range or preserved ejection fraction (EF ≥ 40%). We conducted the first randomized, sham-controlled trial to evaluate the IASD in HF with EF ≥ 40%. Methods -REDUCE LAP-HF I was a phase 2, randomized, parallel-group, blinded multicenter trial in patients with New York Heart Association (NYHA) class III or ambulatory class IV HF, EF ≥ 40%, exercise PCWP ≥ 25 mmHg, and PCWP-right atrial pressure gradient ≥ 5 mmHg...

BACKGROUND: Diabetes mellitus (DM) adversely affects morbidity and mortality for cardiovascular diseases and procedures. Data evaluating the outcomes of transcatheter aortic valve replacement (TAVR) in diabetic patients are limited by small sample size and contradictory results. We aimed to establish the magnitude of risk and the incremental influence of insulin dependency by examining short- and long-term adverse outcomes according to DM status and therapy in the world's largest TAVR registry...

BACKGROUND / PURPOSE: The Lotus valve (Boston Scientific, Natick, MA, USA) is a contemporary transcatheter aortic valve implantation (TAVI) device that is fully repositionable and retrievable to aid implantation and optimise procedural results. The ability to implant the device without routine pre-dilatation is another possible advantage reducing associated risks and procedure times. The aim of this study is to report procedural and 30-day outcomes following TAVI in a consecutive patient group presenting with severe symptomatic aortic stenosis with the Lotus valve system without routine pre-dilatation...
