Selected Abstracts of the TEEPGI 2014 Workshop

Mitral valve perforation is most commonly due to infective endocarditis. Iatrogenic mitral valve perforation following aortic valve replacement has not been described previously. A 57 years male patient presented with complaints of progressive dyspnea on exertion and occasional palpitations. A preoperative diagnosis of severe aortic stenosis, sclerodegenerative aortic valve with normal left ventricle function was made on transthoracic echocardiography. A coronary angiogram showed single vessel disease involving proximal left anterior descending artery causing 80% stenosis. The patient was planned for aortic valve replacement (AVR) and CABG. Pre bypass TEE showed bicuspid aortic valve, thick, calcified, severe aortic stenosis and normal left ventricle systolic function. Mitral valve was morphologically normal with mild central mitral regurgitation jet. Patient underwent CABG and AVR under cardiopulmonary bypass support. Post CPB TEE examination showed 2 jets of mitral regurgitation in midesophageal aortic long-axis view (Fig. 1). There was a mild central MR jet and an additional mild MR jet from the body of anterior mitral leaflet. Transgastric short axis view showed turbulence in the region of A1 scallop of anterior mitral leaflet. We present the intraoperative TEE images of the patient with a discussion on the role of TEE in detection of mitral valve perforation and surgical decision making.
