Spontaneous Spinal Epidural Hematoma in an Adult Patient with Complex Congenital Heart Disease
We report the case of a 27-year-old man who developed sudden upper back pain with no specific precipitant. Five days later, he visited our emergency department complaining of weakness in both lower limbs and dysuria. He had a history of intracardiac repair and a Blalock-Park procedure for an interrupted aortic arch and ventricular septal defect in infancy. Additionally, he had undergone an aortic root dilatation and aortic valve replacement at the age of 10 because of progression of aortic and supra-aortic stenosis and had received chronic anticoagulation and antiplatelet therapy with warfarin and aspirin, respectively. An...

Surgical vs transfemoral aortic valve replacement in low ‐risk patients: An updated meta‐analysis of trial and registry data
ConclusionsEarly mortality is higher in SAVR while rates of PVL and PPMI are substantially higher in TAVR. There is no significant advantage with TAVR for overall survival, cardiovascular death, stroke, MI, and re ‐intervention rates.

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...

Survival and Stroke Similar for TAVR and SAVR at 5 Years Survival and Stroke Similar for TAVR and SAVR at 5 Years

Assistive technology using regurgitation fraction and fractional-order integration to assess pulmonary valve insufficiency for pre-surgery decision making and post-surgery outcome evaluation
This study proposes an assistive technology to quantify regurgitation using the regurgitation fraction (RF) and heart pump efficiency (HPE). In signal preprocessing stage, the detrending and zero-crossing processes are used to remove the unwanted flow fluctuations and identify the end-systolic and end-diastolic periods per each cardiac cycle. The fractional-order integrations are employed to calculate the stroke volume (SV) and regurgitation volume (RV). Then, the regurgitation flow can be quantified that indicates the high correlation with HPE. For a mimicking pulmonary circulation loop system, the proposed screening mode...

Aortic valve repair in the paediatric population: insights from a 38-year single-centre experience CONGENITAL
CONCLUSIONS In our experience, AV repair in the paediatric population provides excellent results in terms of both overall survival and valve-related reoperation. It obviates the need for chronic anticoagulation and in most cases delays the time at which more complex surgery such as the Ross procedure should be undertaken.

Direct oral anticoagulant use in nonvalvular atrial fibrillation with valvular heart disease: a systematic review
In conclusion, subanalyses of DOAC landmark AF trials revealed that dabigatran, rivaroxaban, and apixaban may be safely used in AF patients with certain types of VHD: aortic stenosis, aortic regurgitation, and mitral regurgitation. More evidence is needed before routinely recommending these agents for patients with bioprosthetic valves or mild mitral stenosis. Patients with moderate to severe mitral stenosis or mechanical valves should continue to receive warfarin, as these patients were excluded from all landmark AF trials.
