Red Cell Distribution Width as a Prognostic Marker in Patients Undergoing Valve Surgery.
CONCLUSIONS: An elevated RDW is associated with a worse outcome following valve surgery. The predictive ability of the RDW, when assessed by the area under the ROC curve, improved the predictive ability of the EuroSCORE II calculator. PMID: 30207123 [PubMed - in process]

Cardioembolic Stroke from an Atrial Myxoma in a Pediatric Patient: A Case Report and Review of the Literature.
Authors: Aldajani AA, Mudhry MA, Mir A, Albaradie RS Abstract Cardioembolic stroke is an uncommon phenomenon in pediatric patients. Although the heart is the usual source of the condition, cardiac myxomas are still considered to be a rare cause in children. The case is presented of a 13-year-old, right-handed Saudi boy who showed right-sided weakness for 30 h prior to hospital admission that involved the face, arm, and leg, with slurred speech. The patient had been discharged previously from a local hospital, without active management. An examination showed decreased strength on the right side, with hyperreflexia a...

INR Control of Patients with Mechanical Heart Valve on Long-Term Warfarin Therapy
ConclusionsDespite a majority of patients having <60% TTR, there were low incidences of bleeding and stroke events in this center. There were no factors found to be associated with INR control in this study.

Transfemoral Implantation of the Acurate neo for the Treatment of Aortic Regurgitation.
CONCLUSIONS: In a selected patient population, transfemoral TAVR using the Acurate neo transcatheter heart valve was successful in treating aortic regurgitation, significantly reduced left ventricular dimensions, and improved clinical symptoms. PMID: 30012890 [PubMed - as supplied by publisher]

A Review of Alternative Access for Transcatheter Aortic Valve Replacement
AbstractWith the advent of transcatheter aortic valve replacement (TAVR), appropriately selected intermediate-, high-, and extreme-risk patients with severe aortic stenosis (AS) are now offered a less invasive option compared to conventional surgery. In contemporary practice, TAVR is performed predominantly via a transfemoral arterial approach, whereby a transcatheter heart valve (THV) is delivered in a retrograde fashion through the iliofemoral arterial system and thoraco-abdominal aorta, into the native aortic valve annulus. While the majority of patients possess suitable anatomy for transfemoral arterial access, there i...

Non-vitamin K antagonist oral anticoagulants in atrial fibrillation patients with bioprosthetic valves.
Authors: Andrade JG, Meseguer E, Didier R, Dussault C, Weitz JI Abstract INTRODUCTION: The non-vitamin K antagonist oral anticoagulants (NOACs), which include dabigatran, apixaban, edoxaban and rivaroxaban, are preferred over vitamin K antagonists for stoke prevention in most patients with non-valvular atrial fibrillation. The NOACs are contraindicated in atrial fibrillation patients with rheumatic mitral stenosis or mechanical heart valves. There is evidence that bioprosthetic heart valves are less thrombogenic than mechanical heart valves, but it is unknown whether the risk of thromboembolism in atrial fibrillati...

Propensity Score Matched Analysis of Mechanical vs. Bioprosthetic Valve Replacement in Patients With Previous Stroke.
CONCLUSIONS: In patients with previous stroke, bioprosthetic valves had a lower incidence of complications connected to major bleeding than did the mechanical valves. Survival and stroke recurrence rates, however, did not differ between the 2 groups. We recommend bioprosthetic valves for patients >60 years or who have a history of GI bleeding.

Pulmonary Hypertension as a Possible Cause of Paradoxical Low-Flow, Low-Gradient Aortic Stenosis.
Authors: Watanabe Y, Higashi H, Inoue K, Aono J, Okura T, Higaki J, Ikeda S Abstract Paradoxical low-flow, low-gradient aortic stenosis (LFLG AS) is recognized as a subtype of aortic stenosis. A small left ventricular (LV) cavity with marked LV concentric remodeling leads to a reduced stroke volume in this condition. The case is reported of a paradoxical LFLG AS patient who was undergoing treatment for pulmonary hypertension (PH) and interstitial pneumonia associated with scleroderma. Echocardiography demonstrated enlargement of the right ventricle and a diminished LV cavity. Moreover, the aortic valve opening was ...

Impact of Heart Rate on Flow Measurements in Aortic Regurgitation.
CONCLUSIONS: An increased heart rate leads to a decreased RV. The RF is more stable and may therefore be preferable for severity grading in AR. PMID: 29762918 [PubMed - in process]

Outcomes with a latest generation self-expandable, intra-annular, re-sheathable transcatheter heart valve system: analysis of patients with impaired left ventricular function and determinants for pacemaker implantation
ConclusionsThe Portico valve demonstrates a satisfying safety outcome, especially for patients with impaired LV function. Results of the CE-mark trial were confirmed, except for higher PPM rates. PPM rates are in accordance with other reports on this TAVI platform.

‘Ten Commandments’ of the EHRA Guide for the Use of NOACs in AF
Non-vitamin K antagonist oral anticoagulants (NOACs) are an alternative for vitamin K antagonists (VKAs) to prevent stroke in patients with atrial fibrillation (AF), and have emerged as the preferred choice, particularly in patients newly started on anticoagulation. Both physicians and patients are becoming more accustomed to the use of these drugs in clinical practice. However, many unresolved questions on how to optimally use these agents in specific clinical situations remain. In 2013, the first “EHRA Practical Guide” was published to provide practical guidance for situations; an update was published in 2015. Below ...

Comparative analysis of balloon- versus mechanically-expandable transcatheter heart valves considering landing zone calcification.
CONCLUSION: Both THVs yield comparable procedural and clinical outcomes except for a higher PPI rate with the Lotus valve, which is independent from the extent of landing zone calcification. The extent of landing zone calcification is associated with an increased risk for PVL for both THV, but is significantly reduced with the Lotus valve.

Transcatheter Aortic Valve Implantation in High-Risk/Inoperable Patients: Repositionable versus Non-Repositionable Self-Expanding Valve.
CONCLUSIONS: In comparison to last-generation CVS, the repositionable ERS is safe and effective in HRI patients. Similar rates of PM use were noted for each group. together with a favorable hemodynamic performance and fewer vascular complications. PMID: 29302939 [PubMed - in process]

Long-Term Results of Aortic Root Surgery in Marfan Syndrome Patients: A Single-Center Experience.
CONCLUSIONS: The Bentall and David operations are both associated with satisfactory long-term results in MFS patients. The low rate of valve prosthesis-related complications suggested that the Bentall operation would continue to be a standard surgical treatment. The reimplantation technique, adopted for less-dilated aortas, provides satisfactory freedom from reoperation. Careful attention should be paid to the reimplantation technique in patients affected by a serious familiar genetic phenotype. PMID: 29302938 [PubMed - in process]
