Propensity-matched comparison of balloon-expandable and self-expanding valves for transcatheter aortic valve replacement in a Chinese population.

Background: Balloon-expandable valves (BEV) and self-expanding valves (SEV) for transcatheter aortic valve replacement (TAVR) have shown promising results in Western populations. Herein, we comparatively evaluated their hemodynamics and early clinical outcomes in a Chinese population.

Methods: One hundred seventy-eight patients with symptomatic aortic stenosis who had undergone transfemoral TAVR using SEV (n=153; Venus-A, 97; VitaFlow, 56) or BEV (n=25; Sapien3) from September 2020 to April 2021 were retrospectively enrolled, and 25 pairs were propensity-score matched for 10 baseline variables.

Profile and outcomes of patients with mediastinal hematoma after cardiac catheterization: A retrospective analysis.

Objective: To provide a comprehensive introduction of mediastinal hematoma.

Background: Mediastinal hematoma is a rare complication that is usually not considered in the differential diagnosis of chest pain after cardiac catheterization.

Methods: From January 1, 2006, to December 31, 2013, at Fuwai Hospital, 126,265 patients underwent coronary angiography (CAG); 121,215 of them underwent CAG via the radial artery.

Abnormalities of myocardial perfusion and glucose metabolism in patients with isolated left ventricular non-compaction.

Background: The prevalence of myocardial perfusion and glucose metabolic abnormalities and their significance in patients with isolated left ventricular non-compaction (ILVNC) have not been well investigated.

Methods: Seventeen ILVNC patients who underwent cardiac magnetic resonance (CMR) and (99m)Tc-sestamibi SPECT/fluorine-18 deoxyglucose ((18)F-FDG) PET imaging were included. Left ventricular non-compaction, regional wall motion abnormalities, left ventricular ejection fraction (LVEF), and delayed enhancement (DE) were estimated using CMR.
