Estimation of the orifice area is of major importance in the timing of valve dilation or surgery in patients with mitral stenosis. Determination of the area has traditionally been accomplished at cardiac catheterization by the Gorlin equation. The va

Percutaneous transluminal balloon valvuloplasty was attempted in 92 adult patients with severe calcific aortic stenosis. The mean age was 75 ± 11 years (range 38 to 91) and 35 patients were more than 80 years old. Most of the patients were severely

A new, simple and reliable model of atrial flutter utilizing postpericardiotomy pericarditis was developed in the dog. Using a sterile technique, the pericardium was opened by way of a right thoracotomy, Teflon-coated, stainless steel wire electrodes

The development of a perivalvular abscess as a complication of infective endocarditis adds appreciably to the expected morbidity and mortality of patients, but such abscesses are seldom recognized by available noninvasive techniques. Therefore, two-d

Pulsed Doppler echocardiography has been used previously to demonstrate marked changes in transvalvular blood flow velocities during cardiac tamponade in laboratory animals and a small number of patients. To further assess the respiratory changes in

During the 35 month period ending December 1987, 30 children, aged 14 days to 13 years, underwent balloon angioplasty of unoperated aortic coarctation with resultant reduction in coarctation gradient from 43.6 ± 20.4 to 9.5 ± 7.6 mm Hg (p < 0.001).

To identify the correlates of a second restenosis after repeat percutaneous coronary angioplasty, the records of 384 patients with single vessel disease who underwent repeat angioplasty for restenosis complicating a first elective angioplasty were ex

Both Palmaz-Schatz stents (PSS) and directional atherectomy (DCA) are reported to be suitable for treating restenotic lesions and claim to decrease subsequent restenosis. The purpose of this study was to compare in hospital outcome and follow-up (FU)

No-reflow phenomenon after angioplasty or atherectomy may result in important ischemic complications. No-reflow phenomenon is related to distal embolization of microparticulate material and/or spasm in the microcirculation. Maximal vasodilatation of

We investigated the effect of modifying total biphasic shock duration (SDur) in 7 anesthesized pigs while keeping pulse 1/pulse 2 duration ratio constant (60%/40%; pulse 1 = first part, pulse 2 = second part of biphasic shock). Different SDurs of 10.
