Comprehensive Dynamic 3-Dimensional Analysis of the Tricuspid Valve in Functional Tricuspid Regurgitation: Implications for Prophylactic Tricuspid Valve Intervention.

Objectives: To track and measure changes in the tricuspid annulus (TA) using 3-dimensional (3D) echocardiography during a complete cardiac cycle in patients with functional tricuspid regurgitation (TR) compared to patients without TR, and to compare tricuspid annular plane systolic excursion (TAPSE) derived from 2-dimensional (2D) and 3D coordinates as a measure of right ventricular (RV) function to the standard method of 2D fractional area change (FAC).

Design: Intraoperative 3D echocardiography data were collected prospectively, followed by postprocessing software analysis to track and reconstruct changes throughout the cardiac cycle.

Setting: Data were collected from 108 patients undergoing left-sided heart surgery at 2 large academic centers-Beth Israel Deaconess Medical Center in Boston, MA and Rhode Island Hospital, Providence, RI-between November 2018 and April 2020.

Hypercapnia during transcatheter aortic valve replacement under monitored anaesthesia care: a retrospective cohort study.

Background: Acute intraoperative hypercapnia and respiratory acidosis, which can occur during monitored anaesthesia care (MAC), pose significant cardiopulmonary risks for patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). The goal of the present study is to assess the incidence, risk factors and impact of intraoperative hypercapnia during MAC for patients undergoing transfemoral TAVR.

Methods: Data was collected retrospectively from the electronic medical record of 201 consecutive patients with available intraoperative arterial blood gas (ABG) data who underwent percutaneous transfemoral TAVR with MAC using propofol and dexmedetomidine.

Serum Levels of Bupivacaine After Bilateral Ultrasound-Guided Deep Parasternal Intercostal Plane Block in Cardiac Surgery with Median Sternotomy.

Objective: To evaluate systemic levels of bupivacaine after bilateral ultrasound-guided deep parasternal intercostal plan (PIP) block in cardiac surgical patients undergoing median sternotomy.

Design: Prospective, observational study SETTING: Single institution; academic university hospital PARTICIPANTS: Twenty-eight adult patients undergoing cardiac surgery with median sternotomy received a PIP block with 2.5 mg/kg bupivacaine with or without dexamethasone and dexmedetomidine.

Hemodynamic Monitoring In The Cardiac Surgical Patient: Comparison of Three Arterial Catheters.

Objective: Systemic systolic (SAP) and mean (MAP) arterial pressure monitoring is the cornerstone in hemodynamic management of the cardiac surgical patient, and the radial artery is the most common site of catheter placement. The present study compared 3 different arterial line procedures. It is hypothesized that a 20-G 12.
