OBJECTIVES This study examined: 1) the impact of myectomy on postoperative mitral regurgitation (MR) and 2) the association between the severity of MR and the left ventricular outflow tract (LVOT) gradient. BACKGROUND For patients with hypertrophic obstructive cardiomyopathy (HOCM) and MR, controversy exists as to whether myectomy alone is sufficient in eliminating MR. Furthermore, the relati...

Severe bioprosthetic mitral valve calcification is a significant problem in cardiovascular surgery. Unfortunately, clinical markers did not demonstrate efficacy in prediction of severe bioprosthetic mitral valve calcification. Here, we examined whether a genomics-based approach is efficient in predicting the risk of severe bioprosthetic mitral valve calcification. A total of 124 consecutive Rus...

Prosthetic aortic valve and conduit dehiscence with periconduit cavity and ascending aortic aneurysm is an uncommon complication of aortic root surgery. It is usually recognizable at echocardiography due to an abnormal position of the prosthetic valve and conduit in relation to the native aortic annulus in conjunction with an abnormal echolucent periconduit space that fills with color flow. Mit...

To determine the echocardiographic and Doppler characteristics of mitral regurgitation associated with a flail mitral valve, precordial and transesophageal echocardiography with pulsed wave and Doppler color flow mapping was performed in 17 patients with a flail mitral valve leaflet due to ruptured chordae tendineae (Group I) and 22 patients with moderate or severe mitral regurgitation due to o...

BACKGROUND To report early and long-term outcomes of patients undergoing minimally invasive mitral valve surgery (MIMVS) through right mini-thoracotomy (RT) over a 10-year period. METHODS From September 2003 to December 2013, a total of 1604 consecutive patients underwent MIMVS through RT. RESULTS The mean age was 63 ± 13 years, 770 (48 %) patients were female and 218 (13.6 %) had previous ...

Sutureless aortic valve replacement (AVR) was developed as an alternative treatment option to conventional open-heart surgery and transcatheter aortic valve implantation for "gray zone" patients. The need for concurrent mitral valve surgery is generally viewed as a contraindication to sutureless AVR. The purpose of this brief paper is to report our experiences with sutureless valves in patients...

Objective: Microwave ablation in conjunction with open heart surgery is effective in restoring sinus rhythm (SR) in patients with atrial fibrillation (AF). In patients assigned for isolated mitral valve surgery no prospective randomized trial has reported its efficacy. Methods: 70 patients with longlasting AF where included from 5 different centres. They were randomly assigned to mitral valve s...

Left atrial thrombus in the presence of diseased mitral valve and atrial fibrillation is a well known entity. But it is very rare to occur in the presence of normal mitral valve apparatus. We report the case of a 36 year old female who presented with left atrial ball valve thrombus and normal mitral valve apparatus and underwent surgery. This patient with gangrene of right lower limb came for c...

Exposure of the mitral valve is of critical importance in mitral valve surgery. The mitral valve is located near the interatrial groove. As we accumulated experience and learned from embryology, we found that a more central left atriotomy was advantageous, and was made possible by interatrial groove dissection using an ultrasonic scalpel. This crucial finding prompted us to report the technique.

From Cutler’s first attempt to treat the mitral valve by inserting a tenotomy knife through the left ventricle, to Carpentier’s introduction of several repair techniques and a functional classification for assessing mitral valve lesions, the history of mitral valve treatment is exciting. Mitral diseases may be degenerative, ischaemic, infective or rheumatic, with or without superimposed impaire...
