2.Minimally Invasive Mitral Valve Surgery.
Hanyang Medical Reviews 2007;27(2):49-56
In general, cardiac surgery has been performed via median sternotomy. During the past decade, improvement in endoscopic equipments and operative techniques have resulted in development of the minimally invasive cardiac operation using small incisions. Today minimally invasive mitral valve surgery has become standard practice for many surgeons and robotic systems are gaining wider adoption.

4.Study on heart lesions of mitral valve disease with indicated transesophagel heart ultrasonic surgery
Journal of Practical Medicine 2005;0(12):11-14
Research and compare diagnosis capacity heart injures in mitra valve disease by transthoracic and transesophageal echocardiography. The research was carried by …..and interrupt method with desciptive, analytic and comparetive steps on 56 patients at Bach mai hospital from 10/2003 to 3/2004. The result showed that: transesophageal echocardiography is an explorative method with high accuracy. Evaluation for valve injure condition and organize under valve of transesophageal heart echocardiography method is more accurate than transthoracic echocardiography.

A 27 year-old female presented with dyspnea on exertion, and was diagnosed using transthoracic and transesophageal echocardiography as congenital double-orifice mitral valve and mitral valve prolapse resulting in severe mitral regurgitation. This finding was confirmed by open heart surgery, and her mitral valve was successfully repaired with lateral commissural repair and ring annuloplasty using da Vinci system. We report this case with review of literature.

OBJECTIVETo analyze the clinical, echocardiographic features and therapy efficacy of patients with ruptured mitral chordae tendineae.
METHODSClinical data, echocardiographic and pathological results from 292 hospitalized patients with ruptured mitral chordae tendineae were retrospectively analyzed.
RESULTSThere were 99 cases (33.9%) with rupture of anterior leaflet and 180 cases (61.6%) with rupture of posterior leaflet, 13 cases (4.5%) with both anterior and posterior leaflet ruptures. Partial rupture of mitral chordae tendineae was found in 266 cases (91.1%) and total rupture in 26 cases (8.9%). Two hundred and fourteen cases (73.3%) were primary chordal rupture and 78 (26.7%) were secondary chordal rupture (P < 0.05). Primary chordal rupture was mostly due to mucus degeneration of the mitral valve, mostly presented as posterior leaflet rupture in aged male patients. Secondary chordal rupture was mostly caused by infective endocarditis, coronary heart disease, congenital heart disease and rheumatic heart diseases. Patients with secondary chordal rupture cases were significantly younger than patients with primary chordal rupture and there were significantly more anterior leaflet rupture than posterior leaflet rupture. One hundred and thirty patients received mitral valve reconstruction operation and another 110 underwent mitral valve replacement therapy and discharged complication free. The remaining 52 cases received medication therapy and discharged with improved symptoms (12 with mild chordal rupture without operation indication, 17 cases contraindicated to operative therapy, 7 cases transferred to other hospitals and 16 patients refused operation therapy).
CONCLUSIONSThe incidence of posterior leaflet rupture is higher than that of anterior leaflet rupture. Rupture of both anterior and posterior leaflet is rare and there are more primary chordal ruptures than secondary chordal ruptures based on our patient cohort. Mitral valve reconstruction operation and mitral valve replacement therapy are effective operative therapy options for the treatment of mitral chordal ruptures in indicated patients.

9.Surgery for obstructive hypertrophic cardiomyopathy: challenge and future.
Chinese Journal of Surgery 2023;61(3):181-186
After more than 60 years of development, with the deepening of the pathophysiological understanding of obstructive hypertrophic cardiomyopathy, the extent and resection thickness of myectomy have increased significantly. Myectomy combined with the correction of anomalies of the mitral valve apparatus has become the standard treatment of obstructive hypertrophic cardiomyopathy. Only a few centers worldwide can routinely perform it due to the difficulty. Because of the advances of new drugs and interventional therapy, the development of surgical treatment faces many challenges. At the same time, generations of cardiovascular surgeons are constantly trying to promote septal myectomy, including developing devices and the surgical field, as well as improving surgical planning by advanced technology. At present, the superior long-term efficacy of septal myectomy has been confirmed. It is necessary to work together to promote the treatment of hypertrophic obstructive cardiomyopathy, so as to guard people's health.

10.Evaluation of correlation between pulmonary arterial pressure and left atrial pressure in patients with mitral stenosid and comparison the results before and after operation for close valve spliting
Journal of Practical Medicine 2002;435(11):11-13
23 patients with mitral stenosid with or without mild mitral open, ages of 23-50 (male: 10) received an operation. As the results of direct measurement of pulmonary arterial pressure and left atrial pressure in an operation have shown that the pulmonary arterial pressure was direct correlated before and after operation(r= 0.572 before operation; r=0.65 after operation).These parameters were reduced significantly and rapidly after operation when comparing with these before operation.
