Aortic dissection limited to one sinus of Valsalva has been described exclusively as an iatrogenic complication during catheterization interventions. This life-threatening subtype had a very small area of dissection, when coronary ostia are frequently involved. We report a 43-year-old man with dissection limited to left sinus of Valsalva, involving the left main coronary artery and causing non-ST-myocardial infarction, including severe reversible ST-depression, maximum of 9 mm in V5 lead. Dissection was suggested by cineangiography, transesophageal echocardiogram, and contrast-enhanced multidetector computed tomography. Surgical treatment was successful. There were not any associated diseases in the sinuses of Valsalsa, aortic valve or coronary arteries. Unlike previous reported cases of aortic dissection with such limited localization, the present case was spontaneous, and not iatrogenic.

This is to demonstrate a new 2D-ultrasonographic technique which enabled clear resolution of deformed valves, visualization of venous reflux and quantitation of valve incompetence. In a 59-year-old Japanese female patient, ultrasonography was done using Aplio, Toshiba Medical Systems Co., Japan, equipped with 8 MHz linear probe capable of differential tissue harmonic imaging to diagnose the cause of her leg edema. Venous ultrasonography using this device at the popliteal venous valve in this patient demonstrated clear view of deformed venous valve and valve separation at one end of valvular agger while the other part of the valve is closed. Color Doppler failed to show venous reflux due to its low velocity. However, the appearance and disappearance of a thrombus-like echo could be imaged using 2D-ultrasonography. In addition, we were able to demonstrate the time-course change of valve opening and closing, and quantitate the valve incompetence using M-mode ultrasonography.

A 57-year-old man presented with triple valve infective endocarditis. There were vegetations on the tricuspid, mitral, and aortic valve. He had multiple complications such as pulmonary abscess, severe anaemia, and congestive heart failure. His general condition was extremely poor. Intensive medical therapy, such as blood transfusion, mechanical ventilation, and inotropic support, allowed him to tolerate surgery. Triple valve replacement was successfully performed without major complication. Vegetation cultures grew Streptococcus bovis and Enterecoccus faecalis. At 1 year follow-up, the patient is alive in NYHA functional class I.

Atropine added to exercise stress testing in patients who cannot achieve their 80% age-related HR is a safe, well-tolerated, and feasible method for MPS.
