Authors: Erbel R Abstract The progress in cardiology during the last 50 years can best be studied by looking at the diagnostics and treatment of patients with aortic valve stenosis. Previously, the clinical examination, electrocardiography (ECG) and chest X‑ray were used before heart catheterization, which included a transseptal puncture to complete the indications for surgery in young patients. Nowadays, echocardiography, often combined with a dobutamine stress test, is the primary diagnostic tool to which computed tomography for quantification of valve calcification and cardiac magnetic resonance...

Conclusion: These findings indicate that AS is associated with a high prevalence of SBI, and that the CHA2DS2-VASc score and eGFR are useful for risk stratification.Cerebrovasc Dis Extra 2020;10:116 –123

Authors: Brito D, Goykhman I, Lo KB, Alhamshari Y, Peñalver JL, Aguilar F, Quintero E, Kalla A, Friend E, Pressman GS Abstract Aortic stenosis (AS) is common and increasing in prevalence as the population ages. Using computed tomography (CT) to quantify aortic valve calcification (AVC) it has been reported that men have greater degrees of calcification than women among subjects with severe AS. These data, however, were derived in largely Caucasian populations and have not been verified in non-Caucasian subjects. This retrospective study identified 137 patients with severe AS who underwent valve replacement a...

ConclusionPreoperative MDCT in patients undergoing SAVR is a useful tool for lifetime management, particularly in patients with tricuspid AS. Decisions for surgical management may change based on MDCT's ability to predict intraoperative SAVR size and determine which patients may be high ‐risk candidates for future ViV TAVR due to coronary artery obstruction.

A 71-year-old Jehovah ’s witness woman with a past medical history significant for diabetes mellitus, hypertension, breast cancer, aortic stenosis, and coronary artery disease underwent three-vessel coronary artery bypass graft (CABG) and surgical aortic valve replacement (SAVR) with a 19 mm Sorin Mitroflow (Sorin Grou p, CO, USA) (True internal diameter 15.4 mm). Severe patient prosthesis mismatch (PPM) (EOAi: 0.30 cm2/m2) was diagnosed shortly after surgery with post-operative mean gradients of 40 mmHg by echocardiography.

This study compared mean differences and correlations for AVA by planimetric (2-dimensional transesophageal echocardiography [2D TEE], 3-dimensional transesophageal echocardiography [3D TEE], 3-dimensional transthoracic echocardiography [3D TTE], multi-detector computed tomography [MDCT], and magnetic resonance imaging [MRI]) with hemodynamic methods (2D TTE and catheterization) using pairwise meta-analysis.

Purpose: Identify a measurable parameter from test bolus of computed tomography angiography that can differentiate aortic stenosis patients with normal systolic function from those with heart failure and reduced ejection fraction (HFrEF). Materials and Methods: This retrospective study included patients (undergoing evaluation for transcatheter aortic valve replacement) who had retrospective electrocardiogram-gated cardiac computed tomography angiography using test bolus. The measured variables were time to peak contrast enhancement in the pulmonary artery (PAtime), in the ascending (AsAotime) and descending aorta (DsA...

Assessment of right ventricular (RV) systolic function in patients with significant secondary tricuspid regurgitation (STR) remains challenging. In patients with severe aortic stenosis treated with transcatheter aortic valve implantation (TAVI), STR and RV enlargement have been associated with poor outcomes. In these patients, speckle tracking echocardiography (STE) may detect RV systolic dysfunction better than three-dimensional (3D) RV ejection fraction (EF). The purpose of this study was to investigate the prevalence of RV dysfunction when assessed with STE in patients with significant STR ( ≥3+) as compared to patie...

AbstractObjectivesAortic valve calcification (AVC) determined by computed tomography has emerged as a complementary measure of aortic stenosis (AS) severity and as a predictor of adverse events. Thus, AVC can guide further treatment decisions in patients with low-gradient AS (LG-AS). We compared the symptomatic and prognostic outcome of patients with low vs. high AVC after transcatheter aortic valve implantation (TAVI).MethodsPatients with an aortic valve area index ≤ 0.6 cm2/m2 and a mean pressure gradient (MPG)
