Neutrophil-to-lymphocyte ratio predicts heart failure readmissions and outcomes in patients undergoing transcatheter aortic valve replacement.
CONCLUSION: NLR predicts all-cause mortality, MACE, and HF hospitalization 1 year after TAVR. NLR with TAVR risk score improved predictability for MACE. Further studies for prognostication using NLR are warranted. PMID: 30595282 [PubMed - in process]

Prosthesis-patient mismatch after transcatheter aortic valve replacement: prevalence and medium term prognostic impact
AbstractProsthesis-patient mismatch (PPM) occurs when the effective orifice area of the prosthesis is too small in relation to the patient's body surface area. There are few data available on the frequency and prognostic impact of PPM after transcatheter aortic valve implantation (TAVI). Our aim was to determine the prevalence of PPM and to investigate its association with medium-term clinical course of patients undergoing TAVI. We included 185 patients undergoing TAVI (79 ± 5 years, 49% male, 98% CoreValve) between April-2008 and December-2014. The effective orifice area (EOA) was determined by transthoracic echocardiogr...

Incidence and in-hospital Safety Outcomes of Patients undergoing Percutaneous Mitral Valve Edge-to-Edge Repair Using MitraClip ® - 5 year German national patient sample including 13,575 implants.
CONCLUSIONS: MitraClip® implantations increased markedly 5.4-fold between 2011 and 2015, with a constant in-hospital mortality and MACCE rate. Our data indicate that edge-to-edge mitral valve repair in MitraClip® technique has acceptable in-hospital safety outcomes in a real world scenario. PMID: 30666965 [PubMed - as supplied by publisher]

Short-Term and Long-Term Outcomes of Patients Undergoing Urgent Transcatheter Aortic Valve Replacement Under a Minimalist Strategy.
CONCLUSIONS: Urgent minimalist TAVR can be safely performed with favorable in-hospital outcomes, while increased 30-day and 1-year mortality rates suggest the importance of appropriate diagnosis and timely treatment of severe aortic stenosis. PMID: 30700628 [PubMed - in process]

Scientists discover new type of immune cells that are essential for forming heart valves
UCLA researchers have identified for the first time the origin of an immune cell that plays a critical role in the formation of healthy heart valves. The findings could pave the way for new treatments for heart valve disorders, which can be caused by congenital defects, aging or disease.Their study, led by Dr. Atsushi “Austin” Nakano, a UCLA associate professor of molecular, cell and developmental biology and member of theEli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, was published in the journal Developmental Cell.Building on previous research by Nakano, which showed that the embr...

Commentary: Mitral repair in symptom-free patients with normal ventricles: Becoming the new normal?
We have all been there. A young, vigorous woman referred to you with severe asymptomatic mitral regurgitation is in your office to discuss surgical repair. You proceed to describe the incision you are going to make somewhere on her chest; the 1% to 2% risk of bleeding, stroke, infection, heart failure, and death; the fact that she may end up with a prosthetic mitral valve requiring lifelong anticoagulation; and the fact that she is going to have to miss a month or more of her Pilates classes because the American College of Cardiology and American Heart Association Task Force on Practice Guidelines (ACC/AHA) says that it is...

Current status and future perspective of structural heart disease intervention.
Abstract Valvular heart diseases are one of the most frequent causes for heart failure. Degenerative diseases of the aortic and mitral valve as well as a dysfunctional tricuspid valve disease result in a worse clinical outcome if severe. Minimal-invasive, surgical and/or catheter-based structural heart disease (SHD) interventions have recently seen a dramatic increase. Transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is a disruptive technology, and next generation devices and careful patient selection will minimize limitations of TAVI such as paravalvular leak, conductance disturbance...

Prognostic value of left atrial strain in patients with moderate asymptomatic mitral regurgitation
AbstractFor patients with asymptomatic mitral regurgitation (MR), the criteria identifying the groups at higher-risk and their clinical outcome are still uncertain. Therefore, in these patients, optimal time of surgery remains controversial. The purpose of this study was to compare left atrial (LA) strain to other echocardiographic left ventricular (LV) and LA parameters for the prediction of cardiovascular outcomes in patients with moderate asymptomatic MR. We enrolled 395 patients with primary degenerative moderate asymptomatic MR. Exclusion criteria were: history of atrial fibrillation, myocardial infarction, heart fail...

Outcome Of Patients Undergoing Transcatheter Implantation Of Aortic Valve With Previous Mitral Valve Prosthesis (OPTIMAL STUDY)
ConclusionsTAVR in patients with a previous mitral prosthesis appears safe and feasible, with good hemodynamic results at 30-day and at longer term follow-up.

Determinants of long-term outcome of repaired pulmonary valve stenosis
ConclusionsGood long-term outcome can be expected after PVS repair, but complications and the need for reintervention may appear. Older age and the presence of cyanosis at PVS repair emerged as predictors of cardiovascular complications and identified a population that may merit stricter control.ResumenIntroducción y objetivosAunque la estenosis de la válvula pulmonar (EVP) se considera una cardiopatía congénita de bajo riesgo, se ha descrito la aparición de complicaciones y necesidad de reintervenir durante el seguimiento. Los objetivos del estudio fueron evaluar los resultados a largo plazo de la EVP reparada e iden...

Sex-Based Differences in Outcomes After Mitral Valve Surgery for Severe Ischemic Mitral Regurgitation: From the Cardiothoracic Surgical Trials Network
ConclusionsWomen with SIMR displayed different echocardiographic features and experienced higher mortality and worse QOL after MV surgery than men. There were no significant differences in the degree of reverse LV remodeling between sexes.

Left Atrial Thrombus Formation in a Patient With Severe Non-rheumatic Mitral Stenosis After Mitral Valve Repair Receiving Dual Antiplatelet Therapy: A Clinical Challenge
A 60-YEAR-OLD, 88-kg, 165-cm woman presented to a community hospital with heart failure 5 years after mitral valve repair for mitral regurgitation. The patient previously suffered an ischemic stroke and was currently treated with dual antiplatelet therapy. Transesophageal echocardiography revealed severe mitral stenosis with a mean transmitral gradient of 10 mmHg and thickening of the posterior left atrial wall. The patient was then transferred to the authors ’ institution for mitral valve replacement.

Common Post Cardiothoracic Surgery Arrhythmias
Cardiac arrhythmias are common after cardiac surgery and have profound sequelae. Bradycardias are typically transient and have reversible causes; however, persistent atrioventricular block is an indicator for permanent pacemaker implantation after valvular surgery. Transcatheter aortic valve surgery is associated with even higher rates of permanent pacemaker implantation. Atrial fibrillation, the most common postoperative arrhythmia, is associated with ischemic stroke, myocardial infarction, congestive heart failure, and short-term mortality. Ventricular arrhythmias have extremely high in-hospital mortality, as well as lon...

Transcatheter and Surgical Aortic Valve Replacement in Patients with Recent Acute Heart Failure
