A 15-year-old girl was admitted for repair of partially unroofed coronary sinus syndrome. A preoperative echocardiographic study disclosed the dilated coronary sinus and a draining blood flow into the right atrium from both the left atrium and the end of the coronary sinus. At surgery, the distal portion of the coronary sinus roof was found to be absent. The defect was repaired through the coro...

A 72-year-old patient with a history of nonobstructive hypertrophic cardiomyopathy type III and atrial fibrillation of several years’ duration presented to the emergency department with dyspnea at rest (New York Heart Association functional class IV). The patient had been using metoprolol, digoxin, furosemide, and warfarin and had a history of significant variations in the International Normali...

The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...

We report a rare case of sinus of Valsalva aneurysm of left aortic sinus, which was bulging into left atrium (LA) distorting mitral valve and rupture into the left ventricle with severe aortic regurgitation in a 25 years old male patient. Due to the rupture, both aortic and mitral valves were irreparable and required a double valve replacement along with the closure of the neck of the aneurysma...

Pacemaker lead malpositioning with subsequent cardiac tamponade is a rare, but serious adverse event. We herein report a case of pacemaker lead malpositioning in a 76-year old female caucasian patient. The lead was malpositioned into the roof of the left atrium after perforation of the superior vena cava, resulting in cardiac tamponade. After fast surgical revision and an uneventful post-operat...

This study investigates people's preconceptions of green roofs and their visual preference for different green roof design alternatives in relation to behavioral, social and demographical variables. The investigation was performed as a visual preference study using digital images created to represent eight different alternatives: gravel roof, extensive green roof with Sedums not in flower, exte...

This paper describes the potential of Radarsat-1 fine beam intensity SAR images in urban mapping and change detection. The main objective was to determine the possibility of building detection e.g. as a function of height, orientation, roof material and roof type in the Helsinki metropolitan region. Altogether 22235 buildings were used to estimate the effect of height, and then 14270 buildings ...

Results Redo open-heart surgery was performed, using femoral cannulation, mild hypothermia at 28°C, and circulatory arrest during 4 minutes, just to open and inspect the aorta. A big cavity acting as the aortic root, with irregular contour was observed. The floor of the cavity was the aortic prosthesis, the roof the beginning of true aortic root including both coronary ostia and the walls were ...
