Implantation of left ventricular assist devices (LVADS) in older patients appears to be an attractive option in the wake of donor shortage and increasing incidence and prevalence of end stage heart failure. Since the inception of the artificial heart program half a century ago tremendous progress in research and development has led to utilization of more sophisticated devices. VADs have therefore emerged as a successful therapy for extending life with meaningful quality. Areas covered: This review will address the use of LVADS as a bridge to transplantation, destination therapy and comparison of LVAD therapy with alternate list heart transplantation in the elderly population...

Approximately one-third of patients with infective endocarditis require surgical treatment, but the ideal procedure that prevents infection ensures long durability and maintains quality of life remains unclear. A 21-year-old man who was diagnosed with aortic active infective endocarditis was referred to our hospital for surgical treatment. Echocardiography showed bicuspid aortic valve, severe aortic regurgitation, a large vegetation, and a paravalvular abscess. We planned to perform elective surgical treatment after antibiotic therapy; however, progression to heart failure required urgent operation...

Herein, we report on a family with Carney complex. Four members of the family underwent a total of 11 open heart operations as well as 9 other operations to treat extrathoracic masses. All the family members met at least 2 major clinical criteria and 1 supplemental criterion. We analyzed their genomic loci, including the protein kinase A regulatory subunit 1 gene. The results revealed no specific mutations, except for a common single nucleotide polymorphism. This case series of Carney complex emphasizes the importance of close longitudinal follow-up because of the high rate of tumor recurrence irrespective of the site...

BACKGROUND: Survival after cardiac surgery of patients formerly affected by lymphoma has not been well defined. METHODS: Forty-five consecutive patients having prior Hodgkin's (HL patients, n=26) or non-Hodgkin's lymphoma (non-HL patients, n=19) underwent on-pump cardiac surgery at the authors' institution (2001-2016). Ischaemic, valvular, and ischaemic plus valvular heart disease were present in 14, 13, and 18 patients, respectively. Concomitant aortic disease was treated in three cases...

Implantable left ventricular assist device (LVAD) therapy is an established treatment for advanced heart failure. LVADs are usually implanted using intra-operative anticoagulation with or without cardiopulmonary bypass. We describe an anticoagulant-free off-pump LVAD implant technique to circumvent potential complications associated with conventional approaches. This technique is safe and is probably the least invasive surgical approach for LVAD implantation.

Survival for hypoplastic left heart syndrome patients following the Norwood procedure is 71-90%. Mortality in patients with Turner's syndrome and hypoplastic left heart syndrome after conventional palliation (Norwood operation) has been reported as high as 80%. This questions the approach of traditional staged palliation. Here, we report a patient with hypoplastic left heart syndrome and Turner's syndrome bridged to orthotopic heart transplantation following a hybrid procedure.

Rev-erb α, known as nuclear receptor 1D1 (NR1D1), regulates circadian rhythm, modulates glucose and lipid metabolism, and inflammatory response. However, little is known about the effect of Rev-erb agonist on the progression of myocardial infarction (MI) and heart failure. To investigate it, wild-type male mice underwent sham-operation or permanent ligation of the left anterior descending coronary artery to create MI model. Rev-erb agonist SR9009 (100 mg/kg/day) or vehicle was intraperitoneally administered...

BACKGROUND: A recent comprehensive report on healthcare quality in Italy published by the Organization of Economic Co-operation and Development (OECD) recommended that regular monitoring of quality of primary care by means of compliance with standards of care for chronic diseases is performed. A previous ecological study demonstrated that compliance with standards of care could be reliably estimated on regional level using administrative databases. This study compares estimates based on administrative data with estimates based on GP records for the same persons, to understand whether ecological fallacy played a role in the results of the previous study...

As transcatheter aortic valve implantation (TAVI) requires multidisciplinary collaboration, operators and the entire heart team must overcome a steep learning curve. A web-based screening and traditional on-site proctoring system were developed for the introduction of TAVI in Japan. To assess the learning curve involved with the introduction of TAVI under the supervision of a novel proctoring system. We divided 749 consecutive patients enrolled in the OCEAN-TAVI study between October 2013 and August 2015 into the trans-femoral (TF, n = 608) and transapical (TA, n = 141) approach groups to compare outcomes in patients who underwent TAVI during the early proctoring period (proctoring group) and after the procedures began to be performed independently (independent group)...

REVIEW
Erin A Fender, Chad J Zack, Rick A Nishimura
Isolated tricuspid regurgitation (TR) can be caused by primary valvular abnormalities such as flail leaflet or secondary annular dilation as is seen in atrial fibrillation, pulmonary hypertension and left heart disease. There is an increasing recognition of a subgroup of patients with isolated TR in the absence of other associated cardiac abnormalities. Left untreated isolated TR significantly worsens survival. Stand-alone surgery for isolated TR is rarely performed due to an average operative mortality of 8%-10% and a paucity of data demonstrating improved survival...

Aims: The detection of increased left ventricular (LV) chamber stiffness may play an important role in assessing cardiac patients with potential but not overt heart failure. A non-invasive method to estimate it is not established. We investigated whether the echocardiographic backward/forward flow volume ratio from the left atrium (LA) during atrial contraction reflects the LV chamber stiffness. Methods and results: We studied 62 patients who underwent cardiac catheterization and measured their left ventricular end-diastolic pressure (LVEDP) and pressure increase during atrial contraction (ΔPa) from the LV pressure waveform...

Primary cardiac lymphoma (PCL) is one of the rarest tumors of the heart. The most common type is diffuse, large B-cell lymphoma. Most often, the right atrium and the right ventricle are involved, and if not diagnosed and treated in time, it can be fatal. In this case, a female patient underwent an urgent operation for a large, infiltrative, right atrial mass. Extensive resection of the lateral walls of both atria and the interatrial septum as well as reconstruction were performed successfully. The pathological evaluation suggested PCL...
