INTRODUCTION AND AIMS The long-term results after surgical repair of rheumatic mitral valve remain controversial in literature. Our aim was to determine the predictive factors which impact the long-term results after isolated rheumatic mitral valve repair and to evaluate the effect of those factors on reoperation and late mortality. METHODS One hundred and four patients with rheumatic valve d...
Objective: To identify perioperative clinical predictors of permanent pacemaker implantation following aortic valve replacement. Design and patients: Prospective cohort study on 276 patients submitted for aortic valve replacement: 267 patients (mean (SD) age, 57.5 (14) years) with no conduction disturbances, and nine patients (67.7 (5) years) with severe conduction disturbances requiring perman...
A 69-year-old woman with a history of surgical mitral valve repair for severe mitral regurgitation 12 years prior presented with a 6-month history of dyspnea on exertion (NYHA functional class II), exercise intolerance, and swelling of her abdomen and lower limbs. On jugular venous examination, giant systolic pulsations with prominent V-waves, known as the Lancisi sign or C-V waves, were noted ...
Pulmonary arterial early diastolic waves (V waves) were investigated in patients and experimental animals with mitral regurgitation. V waves exceeding systolic pressure in the pulmonary artery were recorded in the main pulmonary artery with micromanometer catheters both in patients and animals, eliminating the possibility of catheter artifact. In experimental animals, aortic closure preceded pu...
BACKGROUND The bicaval technique for orthotopic heart transplantation decreases the incidence of tricuspid valve regurgitation when compared with the standard biatrial technique. This study was designed to study the effects of prophylactic tricuspid valve annuloplasty during bicaval orthotopic heart transplantation on survival, renal function, and amount of tricuspid valve regurgitation. METH...
Aims Rheumatic valve diseases are most common etiological valve diseases in developing countries. Urotensin II is cardiovascular autacoid/hormone and may be associated with patients of heart valve diseases. The present study was to measure plasma urotensin II concentrations in patients with left-sided rheumatic valve diseases such as mitral regurgitation (MR) and aortic regurgitation (AR), and ...
Experimental coronary occlusions were carried out in 12 closed-chest dogs to investigate the functional anatomic characteristics of the mitral valve complex during acute myocardial ischemia. Two-dimensional echocardiography was used to assess left ventricular function, the mitral valve complex, and left atrial size. Presence of mitral regurgitation was assessed by left ventricular contrast echo...
A 75 year old man with long-standing rheumatic mitral stenosis who refused surgical intervention was treated with percutaneous balloon valvuloplasty. Prevalvuloplasty evaluation revealed a heavily calcified mitral valve, a mean transvalvular gradient of 18 mm Hg, a Fick cardiac index of 1.7 liters/min per m2, a mitral valve area of 0.6 cm2 and 1 + mitral regurgitation. After transeptal catheter...
A49-year-old man was referred because of an acute myocardial infarction. He had undergone aortic and mitral valve replacements for endocarditis in 1984 (Figure 1). In the early 1990s, the mitral valve had developed a paravalvular leak that was not regarded as consequential. A right-sided mass was noted on the chest roentgenogram, however, that was interpreted as a pericardial “cyst.” The patien...
Developments in endovascular therapies have made stenting a common practice the treatment of peripheral vascular diseases, including venous disorders such as May-Thurner syndrome. The placement stent system carries risk migration which although small occurs with 3% incidence rate and can be life-threatening given pulmonary infarction, tricuspid regurgitation, right-sided heart failure. Herein w...
