Intraoperative TEE

Aniketh Vijay B, Vikrant Vijan, Navin Mathew
Aneurysms of the sinus of Valsalva are very uncommon, with an incidence ranging from 0.1 to 3.5% of all congenital heart defects. Very few cases have been reported in the literature that presented with involvement of two or more sinuses. We report a case of 27-year-old male with a history of exertional breathlessness of one-month duration. After complete evaluation using transesophageal echocardiography (TEE) and multiple detector computed tomography (MDCT) scanning, the patient was diagnosed to have large congenital unruptured sinus of Valsalva aneurysms involving both left and right coronary sinuses with extension into the interventricular septum...

Anesthesia for orthotopic liver transplantation (OLT) is challenging for any anesthesiologist as the patients undergoing this procedure are among the most critically ill. Adding to the underlying complexity of OLT management is the rare complication of an intracardiac thrombus (ICT). Intracardiac thrombi can present following liver allograft reperfusion resulting in high morbidity and mortality. Currently there is no consensus treatment for ICT, and the gold standard for diagnosis is intraoperative transesophageal echocardiography (TEE); these 2 factors lead to a dangerous amalgam of the difficulty in diagnosing and treating the disease...

PURPOSE: Transthoracic (TTE) and transesophageal echocardiograms (TEE) are considered accurate in detecting the presence of left ventricular (LV) thrombus. A persistent LV thrombus poses risks of pump thrombosis and stroke in LVAD recipients. The relationship between preoperative echocardiography and intraoperative findings at LVAD implantation has not previously been studied. METHODS: A retrospective review examined all patients undergoing LVAD placement or exchange from October 2011 to March 2014...

BACKGROUND: Elimination of the left atrial appendage (LAA) attempts to reduce stroke in patients with atrial fibrillation (AF). A retrospective review suggests that various surgical techniques are often unsuccessful and may leave a stump or gap. In a pilot study, we prospectively evaluated 3 surgical techniques with long-term follow up to define effectiveness. METHODS: At a single institution, 28 patients undergoing concomitant AF surgery were randomized prospectively into 1 of 3 techniques of LAA elimination: internal suture ligation (IL), external stapled excision (StEx), and surgical excision (SxEx)...

BACKGROUND: Abdominal complications being rare but results in high mortality, commonly due to splanchnic organ hypoperfusion during the perioperative period of cardiac surgery. There are no feasible methods to monitor intraoperative superior mesenteric artery blood flow (SMABF). Hence, the aim of this study was to evaluate the feasibility and to measure SMABF using transesophageal echocardiography (TEE) during cardiac surgery under hypothermic cardiopulmonary bypass (CPB). METHODOLOGY: Thirty-five patients undergoing elective cardiac surgery under CPB were enrolled...

A 41-year-old man with sudden onset of chest oppression and downslope ST depression was diagnosed as having type A aortic dissection with angina pectoris and aortic regurgitation. Intraoperative transesophageal echocardiogram (TEE) showed intimal flap inverting into the left ventricle through the aortic valve. This case was rare in that transient myocardial ischemia was induced not by dissection of the aortic root reaching the coronary ostia but by back-and-forth movement of the intimal flap, covering the coronary ostia and interrupting the coronary artery flow...

Recent publications provided controversial results indicating that perioperative heparin bridging anticoagulation (HBA) increased the bleeding risk without decreasing the thromboembolic risk in patients undergoing minor surgery. To investigate if this is also the case in high-risk patients undergoing major abdominal malignancy surgery, we retrospectively collected data of 3268 patients over a 10-year period. After the interruption of preoperative antithrombotic agents, HBA was initiated with a prophylactic-dose of unfractionated heparin in 133 patients (HBA group), and 62 patients did not receive HBA (non-HBA group)...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly causing aortic regurgitation usually in the fifth to sixth decade of life. Earlier, the diagnosis was mostly during postmortem or intraoperative, but now with the advent of better imaging techniques such as transthoracic echocardiography, transesophageal echocardiography (TEE), and cardiac magnetic resonance imaging, more cases are being diagnosed in asymptomatic patients. We present a case of a 39-year-old male who was found to have QAV, with the help of TEE, while undergoing evaluation for a diastolic murmur...

Budd-Chiari syndrome (BCS) is a congestive hepatopathy caused by hepatic venous outflow obstruction. Torsion of the remnant liver after extended right hepatectomy is a potential cause of acute BCS, and it can lead to acute liver failure or death. We present a case of intraoperative transesophageal echocardiographic (TEE) diagnosis of acute BCS after extended right hepatectomy. TEE allowed timely detection of acute BCS and consequent inferior vena cava obstruction and decreased right atrial filling as the cause of sudden life-threatening hemodynamic collapse unresponsive to intravascular volume therapy and inotropic support...
