Objectives: Evaluation of pulmonary capillary wedge pressure (PCWP) through right heart catheterization can indirectly provide an estimation of the filling pressure of the left ventricle. Echocardiography can estimate left ventricular compliance using mitral annular tissue Doppler imaging (TDI). The E/e' ratio refers to the correlation between the peak mitral inflow (E-wave) velocity and early diastolic tissue Doppler mitral annular velocity (e'). The main purpose of this systematic review was to establish the correlation between echocardiographic E/e' ratio and PCWP. The correlation between E/e' and left ventricular end-diastolic pressure (LVEDP) was evaluated as a secondary objective.

Design: A systematic review and meta-analysis of observational studies was conducted. The search was based on Medline (PubMed), Scopus, and Web of Science.

Setting: Intensive care unit or cardiac intensive care unit.

Participants: Adult patients.

Interventions: Any study comparing the left ventricular filling pressure obtained by cardiac catheterization (reference) and echocardiographic evaluation, in particular TDI analysis (intervention), were included.

Measurements And Main Results: The pooled analysis included 94 studies from the initially identified 7,304 records. The correlation was 0.48 (95% CI 0.42-0.54, Q = 420.52, I = 84.8%) for PCWP and 0.50 (95% CI 0.38-0.60, Q = 210.91, I = 89.1%) for LVEDP.

Conclusions: The E/e' ratio moderately correlated with PCWP/LVEDP. The correlation was stable irrespective of the sites where e' was measured, but each site has its own limitations for specific patient subpopulations. The correlation was weak in patients with heart failure with a preserved ejection fraction.

Intravascular Sympathetic Stimulation to Facilitate Catheter Ablation of Premature Ventricular Complexes.

Importance: Infrequent intraprocedural premature ventricular complexes (PVCs) limit the efficacy of catheter ablation. Intravascular stimulation of sympathetic nerves via vertebral veins (VVs) has been used to activate cardiac sympathetic tone and may promote PVCs.

Objective: To characterize the ability of direct electrical sympathetic stimulation via VVs to induce PVCs at the time of catheter ablation.

The 2020 American Heart Association Guidelines advise not to perform mitral valve replacement (MVR) during septal myectomy (SM) to alleviate outflow obstruction. This study aims to review outcomes after concomitant mitral valve (MV) intervention versus SM alone. We conducted a comprehensive literature search across Embase, PubMed, and Scopus.

We present a case of an 82-year-old woman who developed sustained heart failure with left ventricular dyssynchrony after the modified Bentall procedure. Persistent circulatory instability and complete atrioventricular block suggested coronary artery stenosis. Multidetector computed tomography revealed stenosis of the grafted portion of the coronary artery.
