Impact of Forward Stroke Volume Response on Clinical and Structural Outcomes After Percutaneous Mitral Valve Repair With MitraClip Structural Heart Disease
Conclusions— FSV increase after MitraClip implantation was associated with more favorable clinical and anatomic outcomes. Severity and pathogenesis of mitral regurgitation and pre-MitraClip FSV predicted postprocedural FSV response.

What Makes New Ischemic Lesions Symptomatic after Aortic Valve Replacement?
Acute cerebral infarctions on diffusion-weighted magnetic resonance imaging (MRI) are common after cardiothoracic surgery. However, most are asymptomatic and we aimed to identify features associated with clinical stroke symptoms.

Impact of low stroke volume on mortality in patients with severe aortic stenosis and preserved left ventricular ejection fraction
ConclusionLow flow defined as SVi  <  30 mL/m2 or SV  <  55 mL is an important outcome predictor in severe AS with preserved LVEF under medical and surgical management. Further studies are needed to prospectively test these values for risk stratification and decision making.

Thrombectomy and reconstruction of the left vertebral artery after total arch replacement: never give up on postoperative stroke
AbstractThe patient was a 64-year-old man who had aortic regurgitation, ischemic heart disease, a transverse aortic aneurysm, and an abdominal-common iliac aneurysm. Concomitant operations including aortic valve replacement, coronary artery bypass grafting, and total aortic arch replacement with elephant trunk technique were performed successfully. The patient developed postoperative cardiac tamponade on the 5th postoperative day, resulting in bulbar palsy due to occlusion of the dominant left vertebral artery. Thrombectomy of the vertebral artery with reconstruction by a saphenous vein was performed. The patient ’s neur...

Inter- and Intra-site Variability of Mortality and Stroke for Sites Performing both Surgical and Transcatheter Aortic Valve Replacement for Aortic Valve Stenosis in Intermediate-risk Patients
Multi-site procedure-based randomized trials may be confounded by performance variability and variability among sites. Therefore, we studied variability in mortality and stroke after patients were randomized to surgical (SAVR) or transcatheter aortic valve replacement (TAVR) in PARTNER-2A.

Early Stroke After TAVR in US Practice
This cohort study uses registry data to describe trends and incidence of 30-day stroke among patients who had undergone transcatheter aortic valve replacement (TAVR) in the first 5 years the procedure ’s use in US clinical practice.

Perioperative changes of the slope in the preload recruitable stroke work relationship by a single-beat technique after mitral valve surgery in functional mitral regurgitation with non-ischemic dilated cardiomyopathy
ConclusionsThe change of slope was dependent on surgical procedures. In functional mitral regurgitation, the slope may be a more sensitive parameter in reflecting the left ventricular contractile function than the left ventricular ejection fraction.

Inter- and intrasite variability of mortality and stroke for sites performing both surgical and transcatheter aortic valve replacement for aortic valve stenosis in intermediate-risk patients
Multisite procedure-based randomized trials may be confounded by performance variability and variability among sites. Therefore, we studied variability in mortality and stroke after patients were randomized to surgical (SAVR) or transcatheter aortic valve replacement (TAVR) in the Placement of Aortic Transcatheter Valves-2A (PARTNER-2A) randomized trial.

Flow, Reflected by Stroke Volume Index, is a Risk Marker in High Gradient Aortic Stenosis Patients Undergoing Transcatheter Aortic Valve Replacement
ConclusionsSVi can further characterise patients with HG-AS and may help to identify those who are at increased risk following TAVR.

Research Articles Ventricular stroke work and vascular impedance refine the characterization of patients with aortic stenosis
Aortic stenosis (AS) management is classically guided by symptoms and valvular metrics. However, the natural history of AS is dictated by coupling of the left ventricle, aortic valve, and vascular system. We investigated whether metrics of ventricular and vascular state add to the appreciation of AS state above valve gradient alone. Seventy patients with severe symptomatic AS were prospectively followed from baseline to 30 days after transcatheter aortic valve replacement (TAVR). Quality of life (QOL) was assessed using the Kansas City Cardiomyopathy Questionnaire. Left ventricular stroke work (SWLV) and vascular impedance...

Flow, Reflected by Stroke Volume Index, Is a Risk Marker in High-Gradient Aortic Stenosis Patients Undergoing Transcatheter Aortic Valve Replacement
ConclusionsSVi can further characterize patients with HG-AS and may help to identify those who are at increased risk after TAVR.RésuméContexteDes outils sont nécessaires pour dépister les patients exposés à un risque accru à la suite d’un remplacement valvulaire aortique par cathéter (RVAC). Le volume systolique indexé (VSI) est une mesure échocardiographique utilisée dans les cas de sténose aortique à faible gradient. Nous avons vérifié si un faible VSI était un marqueur de risque accru chez les patients présentant une sténose aortique à gradient élevé et avons évalué comment la relation entre le ...

Minimally Invasive Placement of the Impella Assist Device is Associated with Low Stroke Risk
Cardiogenic shock is associated with high mortality rate and mechanical circulatory devices are critical in its treatment. The Impella device is a microaxial left ventricular assist device (LVAD) that is inserted through the aortic valve into left ventricular apex. The purpose of the study is to determine the incidence of stroke with the Impella device when it is placed through a minimally invasive approach.

Meta-Analysis of 5-Year Risk of All-Cause Death or Stroke After Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement
Transcatheter aortic valve implantation (TAVI) is an established alternative to surgical aortic valve replacement (SAVR) for patients with severe symptomatic aortic stenosis.1,2 Its indication has expanded from high-risk to include a low surgical risk younger population. Although the short-term results of TAVI and SAVR in patients with intermediate or high surgical risk are similar,1,2 outcomes beyond short-term periods remain unclear. Recently, the results of 5-year follow-up of the Surgical Replacement and Transcatheter Aortic Valve Implantation (SURTAVI) trial has been reported, which showed a similar rate of the compos...
