New Tool to Guide Transcatheter Aortic Valve Replacement

Key points:

Although all patients underwent valve placement in the proper anatomical location, moderate paravalvular leakage (PVL) occurred in four patients, and a second valve was required in two patients, resulting in a device success of 96.3%.
New PPMI within 30 days was required in 11 patients (6.7%), all because of complete atrioventricular block; patients with baseline right bundle branch block (RBBB) had a higher incidence of new PPMI than did those without RBBB (23.8% vs 4.2%; P < .001).
Patients whose device was implanted inside the MS had a significantly lower incidence of new PPMI (overall 2.1% vs 13.4%; P = .005); this finding was consistent in patients with baseline RBBB (6.7% vs 66.7%; P = .004) or without RBBB (1.2% vs 8.2%; P = .041).
By 30 days, there was one death, which occurred as a result of bleeding in a patient with liver cirrhosis after a successful TAVR procedure; four patients experienced disabling strokes, and vascular complications developed in 16 patients.

Prenatal Exercise Cuts Common Pregnancy Complications Moderate-intensity physical activity during pregnancy is known to be safe for the mother and foetus, but does it reduce the risk for medical complications? A new up-to-date review summarises the data, including seven meta-analyses, which establishes that prenatal exercise prevents hypertension disorders in pregnancy (HDP), including gestational diabetes mellitus (GDM). These are the most common medical complications of pregnancy, affecting up to 15% of pregnant women.

Heart Failure, Not Stroke, Most Common Complication of A-Fib The lifetime risk of atrial fibrillation (AF) increased from 2000 to 2022 from one in four to one in three, a Danish population-based study of temporal trends found.

Incremental value of machine learning for risk prediction in tetralogy of Fallot Machine learning (ML) can facilitate prediction of major adverse cardiovascular events (MACEs) in repaired tetralogy of Fallot (rTOF). We sought to determine the incremental value of ML above expert clinical judgement for risk prediction in rTOF.

Can Treating Depression Mitigate CVD Risk? Depression is linked to a significantly increased risk for cardiovascular disease (CVD), particularly in women, new data from a large retrospective cohort study show. Researchers suggest that screening and treating patients for depression may lead to a decreased incidence of CVD.

Gout Increases the Risk for a Wide Range of Cardiovascular Diseases People with gout are 58% more likely to develop cardiovascular disease (CVD), according to a new analysis. This increased risk was observed across 12 different cardiovascular conditions, including heart failure, arrhythmias, and valve diseases.
