Imaging was performed according to the recommendations using a standard cardiac ultrasound machine (Cx50 xMATRIX, Phillips Healthcare, Germany with the X7-2t probe and the S5-1 ultrasound probe for additional transthoracic measurements). Serial imaging was performed before, 4 and 6 h after trauma by an experienced investigator for echocardiography in pigs. The ejection fraction (EF) was calculated as EF (%) = (EDV–ESV) 1/EDV × 100 (EDV = end-diastolic volume; ESV = end-systolic volume). Further, blood pressure curves were measured continuously over 6 h. Thereby, following parameters were determined: heart rate (HR) in beats per minute (bpm), systolic, diastolic blood pressure, and mean arterial pressure (MAP) in mmHg at trauma as well as 1, 2, 3, 4, and 6 h after trauma.
X7 2t probe
Manufactured by Philips
Sourced in Germany
The X7-2t probe is a medical imaging device manufactured by Philips. It is a transducer probe that can be used with compatible Philips ultrasound systems to capture images of the body's internal structures. The probe operates at a frequency range of 2 to 7 MHz and is designed for a variety of clinical applications. The specific details and intended use of the X7-2t probe are not included in this response.

The presence of PFO was defined as (1) confirmation of PFO using TEE or (2) catheter crossing the IAS into the left atrium. TEE was performed on iE33 using the X7-2t probe (Philips Medical System) under local anesthesia. A microbubble test was performed to confirm the right-to-left shunt via PFO at rest and under spontaneous Valsalva maneuver several times. The PFO using TEE was confirmed by the presence of a separation between the septum primum and the septum secundum or by microbubbles crossing from the right atrium into the left atrium through the IAS.
Crossing of catheters into the IAS was attempted in all participants before septal puncture during the AF ablation procedure. A decapolar deflectable electrode catheter (EPstar Snake; Japan Lifeline, Japan, Tokyo) was used for PFO crossing under the guidance of fluoroscopy and intracardiac echocardiography.

Each patient underwent standard transthoracic echocardiography followed by multiplane 2D and real-time 3D-TEE before and 6 months after the catheter ablation. All measurements in AF were conducted in a single beat after serial beats with average R-R interval. Transthoracic echocardiography was performed using IE33, CX50 and EPIQ7 (Philips Medical Systems, Andover, MA), with an X-5 probe. TEE was performed using CX50 and EPIQ7 (Philips Medical Systems), with an X7-2t probe for 2D and real-time 3D images. The 2D and 3D datasets were digitally stored and transferred to the computers for offline analysis.

Transesophageal Echocardiography for Valve Hemodynamics

Transesophageal echocardiography (TEE) was performed to evaluate replacement valve hemodynamic performance at surgery and in a blinded format on the day of explant (6 months postimplantation). Measurements were obtained both at sedated baseline and at a maximum cardiac output achieved via dobutamine administration. 19, 20 Two-dimensional images for dimensions (Figure E1) and Doppler-derived hemodynamic measurements were captured digitally (X7-2T probe; Philips, Amsterdam, The Netherlands). Pressure gradients were calculated by a modified Bernoulli equation.
Valve regurgitation was evaluated by color flow Doppler and graded as none (0, no regurgitant jet), trace (1þ, regurgitant jet limited to immediate valve vicinity), mild (2þ, regurgitant jet limited to RVOT), moderate (3þ, regurgitant jet extending into right ventricular cavity), or severe (4þ, regurgitant jet extended to tricuspid valve). A 6-Fr catheter was advanced via the femoral vein to the heart chambers for simultaneous pressure measurements (PX272 transducer; Edwards Lifesciences, Irvine, Calif).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
