Left Ventricular Outflow Tract Obstruction after Ross-Konno Operation
INTRODUCTION: SAM (systolic anterior motion) is defined as the dynamic motion of the anterior mitral valve leaflet to the left ventricular outflow tract (LVOT) during systole. In this study, we present a case which we encountered with significant left ventricular outflow tract obstruction (LVOTO) related to SAM and developed after Ross-Konno operation. METHOD: A 4-month, 6.2 kg girl underwent b...
متن کاملUse of the Konno procedure in an 80-year-old woman with aortic stenosis, a narrow left ventricular outflow tract, and a small aortic annulus.
This report describes a technique for repairing an aortic stenosis in an elderly patient with a small aortic annulus and a narrow left ventricular outflow tract. Preoperative echocardiography in an 80-year-old woman showed severe aortic stenosis with a narrow outflow tract: the aortic valve area was 0.48 cm(2), the aortic annular diameter was 14 mm, and the left ventricular outflow tract diamet...
متن کاملLeft Ventricular Outflow Tract Tachycardias
Left ventricular outflow tract tachycardia (LVOT-VT) is an uncommon type of idiopathic left ventricular tachycardia (ILVT) thought to be due to cyclic adenosine mono phosphate (cAMP) mediated triggered activity. The arrhythmia can be terminated pharmacologically with calcium channel blockers or beta-blockers [1]. LVOT-VT can arise above or below the coronary cusps and the former variety can als...
متن کاملLeft Ventricular Outflow Tract Obstruction
Patients with hypertrophic cardiomyopathy (i.e., asymmetric septal hypertrophy) may show obstruction to left ventricular outflow under basal conditions or with provocative maneuvers. The presence of dynamic left ventricular outflow tract obstruction in patients with concentric ventricular wall thickening (but without abnormalities of the aortic valve) has been less well appreciated. Clinical an...
متن کاملFibroelastomas of the left ventricular outflow tract
A 70-year-old woman with a longstanding history of a heart murmur, presented with severe shortness of breath and ankle swelling. Her past medical history includes a left mastectomy for breast cancer and Parkinson’s disease. A systolic, a diastolic murmur and bi-basal pulmonary crackles were heard on auscultation. ECG revealed an incomplete right bundle branch block with ST depression in leads V...
