Multi-Plane Transesophageal Echocardiography (MPTEE Mini)

Multi-Plane Transesophageal Echocardiography (MPTEE Mini)

PRIMARY CLINICAL & DIAGNTOSIC USES

1. Miniaturized Transesophageal Echocardiography for Cardiac Assessment

• Primary Use: Provides high-resolution transesophageal echocardiography using a miniaturized, multiplane probe designed for patients where standard TEE probes may be contraindicated or difficult to place. The smaller probe diameter allows for insertion in patients with esophageal strictures, smaller body habitus, or those requiring prolonged monitoring.

• How it helps: For the cardiologist, echocardiographer, and cardiac intensivist, the MPTEE Mini offers advanced cardiac imaging capabilities in a smaller form factor—enabling detailed assessment of cardiac structure, valvular function, and hemodynamics in patients who may not tolerate standard-sized probes. For the patient with complex cardiac conditions or anatomical limitations, the miniaturized probe provides access to critical diagnostic information that might otherwise be unavailable.

2. Prolonged Hemodynamic Monitoring in Critical Care

• Primary Use: Designed for extended monitoring in intensive care settings, the probe can remain in place for up to 72 hours, providing continuous assessment of cardiac function, volume status, and response to therapeutic interventions in critically ill patients.

• How it helps: For the intensivist and critical care team, the MPTEE Mini enables continuous, real-time assessment of cardiac function without repeated probe insertion—tracking left and right ventricular function, assessing volume status, and guiding fluid resuscitation and vasopressor therapy. For the critically ill patient with hemodynamic instability, this continuous monitoring allows for precise, targeted interventions that improve outcomes.

3. Diagnosis of Right Ventricular Failure

• Primary Use: Provides detailed imaging of the right ventricle, which is often poorly visualized with transthoracic echocardiography. The miniaturized probe enables accurate diagnosis of right ventricular dysfunction, a critical determinant of outcomes in cardiac surgery, pulmonary hypertension, and shock states.

• How it helps: For the cardiac anesthesiologist and intensivist, the MPTEE Mini provides the imaging quality needed to accurately assess right ventricular size, function, and pressure overload—guiding management of right ventricular failure that might otherwise go undetected. For the patient with pulmonary hypertension, post-cardiotomy shock, or acute right ventricular failure, accurate diagnosis enables timely intervention that can be life-saving.

4. Pediatric and Congenital Heart Disease Applications

• Primary Use: The miniaturized design is particularly valuable for imaging in infants and children, where standard TEE probes may be too large. The probe provides high-quality imaging for assessment of congenital heart defects, post-surgical repair evaluation, and intraoperative guidance.

• How it helps: For the pediatric cardiologist and congenital heart surgeon, the MPTEE Mini provides the imaging quality needed to assess complex congenital anatomy in smaller patients—guiding surgical repair, evaluating post-operative results, and monitoring hemodynamics. For the infant or child with congenital heart disease, the smaller probe size means access to transesophageal imaging that might otherwise be unsafe or impossible.

5. Intraoperative Guidance for Cardiac Surgery

• Primary Use: Used during cardiac surgical procedures to assess the adequacy of surgical repair, evaluate valve function, and guide de-airing before weaning from cardiopulmonary bypass. The miniaturized probe allows for continuous monitoring without interference with the surgical field.

• How it helps: For the cardiac surgeon and anesthesiologist, the MPTEE Mini provides real-time feedback during cardiac surgery—confirming valve repair adequacy, assessing ventricular function after bypass, and detecting residual lesions before chest closure. For the patient undergoing cardiac surgery, intraoperative echocardiography ensures that surgical repairs are optimal before leaving the operating room, reducing the need for reoperation.

SECONDARY & SUPPORTIVE USES

1. Transcatheter Structural Heart Interventions: Used to guide transcatheter aortic valve replacement, mitral valve repair, left atrial appendage closure, and other structural heart procedures where high-quality imaging is essential.

2. Hemodynamic Assessment in Shock: Provides continuous assessment of cardiac function, volume status, and response to vasoactive medications in patients with cardiogenic, distributive, or hypovolemic shock.

3. Detection of Endocarditis Complications: Identifies vegetations, abscesses, and valvular perforations in patients with suspected infective endocarditis where transthoracic imaging is inconclusive.

4. Assessment of Prosthetic Valve Function: Evaluates prosthetic valve function, detects obstruction, regurgitation, or paravalvular leak in patients with mechanical or bioprosthetic valves.

5. Congenital Heart Disease Monitoring: Used for serial assessment of patients with congenital heart disease throughout their lifespan, particularly when transthoracic windows are inadequate.

6. Research Applications: Used in clinical research protocols investigating hemodynamics, ventricular function, and response to novel therapies in critically ill populations.
