can balloon aortic valvuloplasty help determine appropriate transcatheter aortic valve size
Jacc-cardiovascular Interventions, 2008Co-Authors: Vasilis C Babaliaros, Stamatios Lerakis, Vinod H Thourani, David Liff, Edward P. Chen, Jason H Rogers, Ryan A Brown, Robert A Guyton, Arthur E Stillman, Paolo RaggiAbstract:Objectives We sought to study the potential role of balloon aortic valvuloplasty (BAV) in sizing the aortic annulus in patients before transcatheter heart valve (THV) implantation. Background Despite clinicians9 growing experience with THV procedures, the best method of annulus sizing remains unclear. Methods Twenty-three patients with aortic stenosis (l1.0 cm2) who were undergoing surgical valve replacement were enrolled. Pre-operative echocardiographic measurements of the annulus and computed tomography measurements of valve calcium were made. Intraoperatively, a valvuloplasty balloon of known size and inflatable pressure was inserted into the aortic valve and inflated. The development of intraballoon pressure in addition to the nominal inflation pressure (AIBP) reflected the apposition of balloon and valve. Surgical annulus was measured by cylindrical sizers. Results In patients with tricuspid valves, AIBP was generated in 11 of 12 patients when the balloon diameter was greater than the surgically measured annulus, regardless of leaflet calcification (2 of 10 patients when balloon ≤ surgical annulus). In bicuspid valves, high AIBP (∼1 atm) was encountered with balloons that were within 1 mm of annulus size, and leaflet dehiscence occurred with larger balloons (n = 2 patients). Annulus size was underestimated by transthoracic Echocardiogram and Transesophageal Echocardiogram compared with surgery (p l 0.001): transthoracic Echocardiogram = 21.5 ± 1.8 mm, Transesophageal Echocardiogram = 22.0 ± 1.6 mm and surgical = 23.2 ± 1.9 mm (range 20 to 27 mm, mode 22 mm). Conclusions These data suggest that measuring AIBP during balloon aortic valvuloplasty in tricuspid valves is an important adjunctive measurement of the aortic annulus and may help in determining the appropriate THV size.

esophageal dissection complicating Transesophageal Echocardiogram the lesson to be learned do not force the issue
Journal of The American Society of Echocardiography, 2006Co-Authors: Mikhael F Elchami, Randy Martin, Stamatios LerakisAbstract:Transesophageal Echocardiogram is a very safe procedure, however, it is not devoid of complications. We report a case of esophageal dissection complicating Transesophageal Echocardiogram in a 52-year-old man who was treated conservatively. Moreover, we review briefly the complications of Transesophageal Echocardiogram.

Intracoronary Stent Visualized on Transesophageal Echocardiogram In a Case of Coronary Dissection Complicated by Aortic Dissection
Journal of The American Society of Echocardiography, 2006Co-Authors: Khan Pohlel, Takeshi Arita, Stamatios Lerakis, Randolph P. MartinAbstract:We present a case of a patient presenting with a myocardial infarction with subsequent coronary intervention resulting in a coronary dissection complicated by an aortic dissection. The coronary dissection was treated with coronary stents. Transesophageal Echocardiogram visualized the intracoronary stent within the intimal flap of the aortic dissection. The aortic dissection was successfully managed conservatively.

Transesophageal Echocardiogram to guide valve in valve transcatheter aortic valve replacement of a failed medtronic freestyle aortic prosthesis
Cardiovascular Revascularization Medicine, 2021Co-Authors: Ahmed Elzanaty, Mohammed Mahmood, Mohamed Mhanna, Salik Nazir, John Letcher, Kellie Yenrick, Erica Boonie, Kasi P RamanathanAbstract:Valve-in-valve transcatheter aortic valve replacement (ViV TAVR) is an appealing alternative to surgical intervention on failed aortic prosthesis with comparable safety and efficacy. ViV TAVR has proven to be a technical challenge in stentless bioprosthetic aortic valves like free style aortic valve prosthesis. In this case series of two patients we report the utility of Transesophageal Echocardiogram guidance to help visualize surgical annulus and TAVR deployment.

total coronary vein left atrial drainage
Circulation, 2009Co-Authors: Gonzalo Pizarro, Javier G Castillo, Juan Gaztanaga, Mario J GarciaAbstract:An asymptomatic 54-year-old man with severe mitral regurgitation caused by prolapse and pulmonary hypertension was referred for mitral valve surgery. The resting ECG (Figure 1) and chest radiograph (Figure 2) were unremarkable. A Transesophageal Echocardiogram showed a degenerated mitral valve with rupture of chordae tendineae and leaflet prolapse causing severe mitral regurgitation (Figure 3). Figure 1. Resting ECG. Sinus tachycardia and otherwise unremarkable findings. Figure 2. Posteroanterior and lateral chest radiograph. Normal cardiac contours and normal pulmonary vasculature and parenchyma. A vertebral prosthesis is noted. Figure 3. Preoperative Transesophageal Echocardiogram. Doppler image showing a wide and eccentric jet of mitral regurgitation. Preoperative computed tomographic coronary angiography demonstrated normal coronary arteries; however, all cardiac veins were found to drain into the left …

pulmonary vein thrombosis and peripheral embolization
Chest, 1996Co-Authors: Mario J Garcia, Leonardo Rodriguez, Pieter VandervoortAbstract:A 78-year-old woman was admitted to the hospital with bilateral femoral arterial occlusion. Her medical history disclosed atrial fibrillation and a left thoracoplasty performed 50 years earlier for treatment of tuberculosis. A Transesophageal Echocardiogram demonstrated intraluminal thrombus in a left pulmonary vein. The patient recovered after thromboembolectomy. This case documents another uncommon cause of cardiac thromboembolism in which a Transesophageal Echocardiogram was essential to make the diagnosis.
