Project description:Transposition of great arteries (TGA) can be associated with left ventricle outflow tract (LVOT) obstruction. In the presence of ventricular septal defect (VSD), septal leaflet of tricuspid valve may prolapse through perimembranous VSD or rarely tricuspid valve tissue may override to produce LVOT obstruction. Occasionally, this may be mistaken for vegetation due to associated pulmonary valve endocarditis. We report a case of d-TGA with presumptive pulmonary valve endocarditis and LVOT obstruction that was found to be due to tricuspid valve straddling on transesophageal echocardiography, resulting in change in the surgical plan and thus avoiding catastrophe.
Project description:Physical examination is becoming a lost art. We describe a case of a patient who was referred to us with an initial diagnosis of ventricular septal defect. Discordance between imaging findings and the physical examination led to a diagnosis of an accessory left ventricle, a rare but benign congenital cardiac condition. (Level of Difficulty: Beginner.).
Project description:We report a 47-year-old man who presented with right-sided heart failure. Transthoracic echocardiography revealed a tunnel-shaped communication (ventricular septal defect) between the left ventricle and the right ventricle with a significant left-to-right shunt. The VSD is connected to the lateral wall of the right ventricle by a large tunnel.
Project description:A 63-year-old man presented with generalized fatigue, chills, malaise, dyspnea, intermittent fevers, and 50-pound weight loss of 4 months' duration. Blood cultures were positive for pan-sensitive Streptococcus anginosus. Transesophageal echocardiography showed an 11 mm × 3 mm mobile mass attached to the mitral valve, a 16 mm × 16 mm mobile mass attached to the pulmonary valve, and a small membranous ventricular septal defect. The patient received 12 weeks of intravenous (IV) antibiotics with eventual resolution of the masses. Multi-valve endocarditis involving both the left and right chambers is rarely reported without prior history of IV drug use or infective endocarditis. Our case emphasizes the importance of careful assessment for ventricular septal defects or extra-cardiac shunts in individuals who present with simultaneous right and left-sided endocarditis.
