Submitral left ventricular aneurysm is a rare cardiac pathology. Etiology remains still mysterious, but it is believed to be due to a congenital defect of the fibrous layer of the atrioventricular junction. Surgical closure of aneurysm rim is the therapy of choice, despite the diversity of surgical approaches and techniques. ...

AIMS: Left ventricular remodelling leads to functional mitral regurgitation resulting from annular dilatation, leaflet tethering, tenting, and decreased leaflet coaptation. Mitral valve annuloplasty restores valve competency, improving the patient's functional status and ventricular function. This study was designed to evaluate the mechanisms underlying mitral valve competency after the implantation of ...

Today, mitral valve replacement is performed under cardioplegic arrest with cross-clamping of the ascending aorta. In the case reported here, mitral valve replacement was performed with an on-pump beating heart technique without cross-clamping the aorta because of diffuse adhesion around the tube graft. A 36-year-old man had undergone a Bentall ...

We successfully operated on a patient with a rare complication of left ventricular outflow tract obstruction after mitral valve replacement. In a 57-year-old woman with previous mitral valve replacement, transthoracic echocardiography showed left ventricular outflow tract obstruction as a result of anterior displacement of the mitral prosthesis and local thickening ...

Although sarcomas are the most frequent primary malignant tumor of the heart, they very rarely involve only the left heart valves. A 72-year-old woman was diagnosed with a severe mitral valve disease and referred for cardiac surgery. Preoperative transthoracic echocardiography revealed a cardiac mass involving the mitral and aortic valves. ...

Surgical treatment of patients with congestive heart failure (CHF) has steadily advanced from rescue procedures such as aneurysmectomy, rupture repair, ventricular assist devices (VADs), and transplantation to procedures that can prevent or delay the progression of cardiac dysfunction and failure. The latter include operations such as coronary artery bypass grafting ...

Sub-valvular apparatus preservation after mitral valve replacement is not a new concept, yet to date there has been no quantification of its clinical effectiveness as a procedure and no consensus as to which surgical preservation technique should be adopted to achieve the best immediate and midterm clinical outcomes. This systematic ...

Accessory mitral valve is a rare congenital abnormality and an unusual cause of subvalvular obstruction of the left ventricular outflow tract. Accessory mitral valves are usually detected in children due to symptomatic obstruction; isolated nonobstructive accessory mitral valve is rarely seen in adults. We describe the echocardiographic diagnosis of accessory ...

Ischemic iatrogenic lesions can complicate surgical procedures on the mitral valve. One of the causative mechanisms is direct injury to or distortion of the circumflex coronary artery. The risk of damaging the circumflex coronary artery depends mainly upon the proximity of that vessel to the posterior segment of the mitral ...

Improved quantitative understanding of in vivo leaflet geometry in ischemic mitral regurgitation (IMR) is needed to improve reparative techniques, yet few data are available due to current imaging limitations. Using marker technology we tested the hypotheses that IMR (1) occurs chiefly during early systole; (2) affects primarily the valve region ...

Noncompaction of ventricular myocardium is a unique congenital cardiomyopathy with its own clinical presentation and course. It is more frequently associated with complications of congestive heart failure, thromboembolism and malignant ventricular arrhythmias; however, concomitance of valvular pathologies or infective endocarditis with noncompaction of ventricular myocardium has seldom been reported. We ...

Ischemic mitral regurgitation results from a variable combination of annular dilatation and remodeling of the subvalvular apparatus. Current surgical techniques effectively treat annular dilatation, but methods for addressing subvalvular remodeling have not been standardized. An effective technique for determining the extent of subvalvular remodeling could improve surgical results by identifying ...
