An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled...

AIMS: Percutaneous left atrial appendage (LAA) occlusion is occasionally incomplete, with residual permeability of the LAA on cardiac computed tomography. The cause for this is unclear. Our objective was to determine if residual permeability was related to incomplete endothelialization. METHODS: A total of 35 consecutive patients contraindicated for anticoagulant therapy admitted for LAA occlusion were included; 12 patients received a Watchman device (Boston Scientific) and 23 patients received an Amplatzer Cardiac Plug (St...

Although nonstructural dysfunction of a bioprosthesis caused by pannus formation or native valve attachment has been well described, structural valve deterioration( SVD) caused by calcification or tear of a bioprosthesis, especially a bovine pericardial valve, is very rare in the tricuspid position. We report a case of redo tricuspid valve surgery for SVD 14 years after tricuspid valve replacement( TVR) using a Carpentier-Edwards Perimount (CEP) pericardial valve. A 71-year-old woman was referred to our hospital because of exertional dyspnea and pre-syncope...

In August 2017, the first major recall for cybersecurity vulnerabilities in pacemakers capable of remote connectivity was released that impacted 465,000 United States patients.1,2 The FDA approved a firmware update designed by the manufacturer of the devices as a remediation (Abbott , formally St. Jude Medical). The recall was in response to the public disclosure of vulnerability by an investment firm and produced in a lab environment that could allow an unauthorized party in close proximity to a patient to impact the performance of the device or modify device settings via radio frequency communication...

BACKGROUND:  Transcatheter heart valve (THV) as valve-in-ring is increasingly used in the mitral position. Semi-rigid rings may serve as a more appropriate scaffold for proper anchoring of a THV as they may change from their oval to a round shape thereby fitting to the implanted THV. METHODS:  One rigid and five semi-rigid rings of four manufacturers, Edwards Physio I and II, Sorin 3D Memo, Medtronic Simulus, and St. Jude Medical (SJM) Saddle and SJM Sequin, with sizes 28 to 36 mm and Edwards Sapien III THV 23, 26, and 29 mm were used...

BACKGROUND: Optimal management of advisory implantable cardioverter defibrillator (ICD) leads has not been established. Several studies were reported concerning the lead extraction of advisory ICD leads, but the implant duration of those studies was short. We estimated the efficacy of lead extractions of advisory ICD leads with a relatively longer duration in Japanese patients. METHODS: We retrospectively analyzed 28 patients who underwent a lead extraction at Kokura Memorial Hospital and Tokyo Medical and Dental University Hospital [Fidelis (Medtronic, Minneapolis, MN, USA): n=19, Riata (St...

PURPOSE: The electrical coupling index (ECI) (Abbott, USA) is a marker of tissue contact and ablation depth developed particularly for atrial fibrillation treatment. We sought to evaluate if these measures can be also a marker of lesion efficacy during cavotricuspid isthmus (CTI) ablation for typical right atrial flutter. METHODS: We assessed the ECI values in patients undergoing typical right atrial flutter point-by-point ablation guided by the Ensite Velocity Contact™ (St...

Left ventricular assist device (LVAD) therapy has emerged as an increasingly vital facet of the treatment algorithm for advanced heart failure. Growing experience with LVAD support has led to substantial improvements in outcomes, with 1-year survival rates approaching that of cardiac transplantation. These therapeutic refinements have engendered growing interests in the potential for expanding the clinical indications for LVAD therapy to patients with less advanced heart failure. The primary obstacles to this evolution of care center largely on the prevention and/or management of the adverse events associated with LVAD therapy along with patient preference...

BACKGROUND: The unrest in Syria has resulted in an escalating refugee crisis. The postwar lack of health care infrastructure in Iraq has also resulted in Iraqis seeking health care in neighboring countries. Pediatric cancer is largely curable, although its treatment is expensive and complex. Strategies to implement pediatric cancer care with curative intent in these vulnerable populations are lacking. METHODS: To assess the feasibility of a collaborative approach for the provision of care to displaced children with cancer, this study reviewed the experience of the authors over the past 6 years in Lebanon, the country with the highest number of refugees per capita in the world...
