Mitral valve plasty

A 3-month-old Shetland sheepdog presented with a loud ejection murmur and exercise intolerance. Echocardiography revealed an accessory mitral valve leaflet, characterised by a valve-like structure separate from the mitral valve seen in the subaortic region of the ventricular septum. The left ventricular outflow tract was partially obstructed with a pressure gradient of 12 mmHg. Accessory mitral valve leaflet resection and mitral valvuloplasty were performed during open-heart surgery. Histology performed on the membrane-like structures were indicative of fibrous connective tissues...

Objectives: Mitral valve repair for extensive commissural prolapse is complex; several methods have been reported with variable results. To restore the leaflet area, we introduced an innovative and effective method rather than a simple folding technique through reconstructing a neocommissure with a "collar-like" plasty technique. Methods: From 2016 to 2021, 62 patients with mitral valve extensive commissural prolapse that received the "collar-like" plasty technique were included...

Cerebral cavernous malformations (CCMs) are blood vessel malformations, often untreated if asymptomatic. However, upon cardiac surgery with cardiopulmonary bypass, cerebral edema/hemorrhage may occur. We successful performed mitral valve plasty for a case of severe mitral regurgitation with multiple CCMs. Preoperative head magnetic resonance imaging and strict perioperative management are important.

INTRODUCTION: Myxomatous mitral valve degeneration (MMVD) is an acquired heart disease which sometimes result in pulmonary oedema and left atrial rupture. In previous reports, left atrial rupture has been non-surgically controlled and its prognosis investigated. There is, however, no report concerning surgically treated left atrial rupture with mitral valvuloplasty and follow-up results. OBJECTIVES: This report aimed to develop a surgical strategy for a case of left atrial rupture caused by MMVD...

INTRODUCTION: cardiac valvular diseases (CVDs) are the major cause of cardiovascular morbidity and mortality globally, with predominance of rheumatic heart disease (RHD) in developing countries. Congenital heart defects (CHD) diagnoses are delayed due to socioeconomic factors. This study aims to evaluate the post-operative surgical outcomes of CHD and valvular RHD. METHODS: this study is conducted with 50 patients from Chad, operated on between 2003 and 2012. Post-operative outcomes are evaluated from 2010 to 2012...

In patients with obstructive hypertrophic cardiomyopathy, left ventricular outflow tract (LVOT) obstruction can be created by the hypertrophic interventricular septum (IVS) as well as systolic anterior motion (SAM) of the anterior mitral leaflet (AML). Sufficient septal myectomy is a fundamental surgical technique to treat LVOT obstruction, however, direct surgical management for SAM is another key aspect. Besides the hypertrophic IVS, mitral valve, subvalvular apparatus, and papillary muscle may play important role for SAM and several surgical techniques have been proposed to treat SAM in literature...

Background and Objective: The prevalence of hypertrophic cardiomyopathy (HCM) is estimated to be 1 in 200 to 500 individuals, with systolic anterior motion (SAM) of the mitral valve (MV) and left ventricular outflow tract (LVOT) obstruction present in 60% to 70%. In this narrative review, we aim to elucidate the pathophysiology of SAM-septal contact and LVOT obstruction in HCM by presenting a detailed review on the anatomy of the MV apparatus in HCM, examining the various existing theories pertaining to the SAM phenomenon as supported by cardiac imaging, and providing a critical assessment of management strategies for SAM in HCM...

In Japan, the medical fee revision in April 2018 allowed insurance coverage for robot-assisted cardiac surgery for mitral and tricuspid valve plasty. We started robot-assisted mitral valve plasty by da Vinci system in June 2019. The artificial chordae reconstruction by the loop method, which has been our basic surgical technique so far, has also been adopted in robot-assisted cardiac surgery. The author has performed three dimensional( 3D) endoscopic minimally invasive cardiac surgery( MICS), but now focuses on robot-assisted cardiac surgery because of the delicate procedure and good operability...

Objective: To compare the efficacy of off-pump coronary artery bypass grafting (CABG) or CABG plus mitral valve plasty (MVP) in patients with coronary heart disease complicated with moderate ischemic mitral insufficiency. Methods: The clinical data of 1 050 patients with coronary heart disease complicated with moderate ischemic mitral insufficiency who underwent surgical procedures from January 2009 to December 2020 were analyzed retrospectively. There were 733 males and 317 females, aging (63.3±9.0) years (range: 31 to 83 years)...

Background: Surgical ventricular reconstruction (SVR) has been used to control adverse ventricular remodeling and improve cardiac function in ischemic cardiomyopathy. The purpose of this systematic review and meta-analysis was to collect and analyze all available evidence on the utilization and efficacy of SVR. Methods: An electronic database search was performed to identify all retrospective and prospective studies on SVR for ischemic cardiomyopathy in the English literature from 2000 through 2020...

OBJECTIVES: We present our 25-year experience with valve-sparing aortic root replacement using a straight tube graft (David-I). METHODS: From 1993 to 2019, 677 patients (median age, 56.0 years; range, 42-65) underwent the David-I procedure with a straight tube graft. A total of 24 different surgeons performed these operations. Marfan syndrome was present in 111 patients (16.4%), and bicuspid aortic valve was present in 71 patients (10.5%). Aortic root aneurysm was present in 544 patients (80...

This case report presents a pediatric patient with an aortic root abscess caused by group A β-hemolytic Streptococcus. After aggressive debridement of infected tissue, the continuity between the left ventricular outflow tract and aorta was reconstructed with autologous pericardium, and the aortic valve was replaced with a mechanical prosthesis using the Konno procedure with concomitant mitral valve plasty. We believe that radical resection of the abscess is an effective way to eradicate such a life-threatening infection...

A 21-year-old female patient referred to our institute had been suffering from severe mitral valve regurgitation due to a rare anomaly: a typical cleft at the posterior mitral leaflet and the other partial one at the anterior leaflet. We successfully fixed the mitral valve using the robot-assisted totally endoscopic technique which could perform suture closure of both leaflets and annuloplasty. This communication is the first report of the robotic and totally endoscopic procedure which could treat this rare mitral anomaly...

We experienced 3 cases of port-access robot-assisted totally endoscopic technique for mitral valve repair and concomitant coronary artery bypass. The right internal mammary artery was harvested, mitral valve was fixed, and the right internal mammary artery to right coronary artery anastomosis was carried out on the arrested heart. The use of cardiac arrest and a V-shaped hook technique facilitated the coronary anastomosis and the da Vinci Firefly test (Intuitive Surgical Inc., Sunnyvale, CA) could confirm patency of the graft...

Objective: In the current study, we present our mid-term experience with modified edge-to-edge repair technique through a transventricular and transaortic route in patients requiring left ventricular remodeling or aortic root/valve surgery. Methods: From December 2006 through April 2015, 49 high-risk patients (median age: 69 years; median European System for Cardiac Operative Risk Evaluation II: 11.4 [6.54-14.9]) underwent transventricular (N = 7; 14%) or transaortic (N = 42; 86%) edge-to-edge mitral valve repair...

An 81-year-old female underwent mitral valve plasty and tricuspid annuloplasty using an artificial annulus for mitral valve insufficiency and secondary tricuspid valve insufficiency at our hospital. Echocardiography 5 months later showed no abnormal finding. Eight months after the operation, however, a pedunculated and highly mobile mass in the right atrium was found, and the patient was admitted to our hospital. Its shape was really uncommon, and it was difficult to differentiate between a thrombus and a tumor...

Infective endocarditis (IE) due to Proteus mirabilis is rare. Given that cases of IE complicated with a left ventricular pseudoaneurysm (LVP) caused by P. mirabilis have not been reported thus far, here we report a case of IE complicated with an LVP caused by P. mirabilis . An 83-year-old woman was admitted to our hospital for urinary tract infection, and P. mirabilis was detected in blood cultures. Transesophageal echocardiography and electrocardiogram-gated computed tomography revealed mitral regurgitation and a mass protruding from the mitral annulus on the dorsal side...

OBJECTIVES: The aim of this study was to evaluate the surgical outcome of patients suffering from native aortic valve (NVE) or prosthetic aortic valve endocarditis (PVE) treated with the EDWARDS INTUITY Elite rapid-deployment valve prosthesis. METHODS: Between February 2019 and June 2020, 25 patients suffering from NVE (n = 9; 36%) and PVE (n = 16; 64%) of the aortic valve received an INTUITY valve at our institution. Preoperative, operative and follow-up data were collected...

BACKGROUND: Surgical therapy of infective endocarditis (IE) involving aortic valves and mitral valves is widespread. However, there are few reports concerning patients with culture-negative endocarditis complicated by the appearance of comorbid valvular perforation and abscess. Therefore, real-time surveillance of changes in cardiac structure and function is critical for timely surgical management, especially in patients who do not respond to medical therapy. CASE SUMMARY: Here, we report an atypical case in a 9-mo-old infant without congenital heart disease but with symptoms of intermittent fever and macular rashes...

The case was a 32-year-old man. Blalock-Taussig shunt was performed at five months-old for tetralogy of Fallot, and intracardiac repair was performed at four years-old. He was admitted with a diagnosis of infective endocarditis. Preoperative echocardiography showed vegetations on the mitral valve and severe mitral regurgitation. Severe right heart pressure load findings, pulmonary valve stenosis and regurgitation, and residual ventricular septal defect were also observed. The surgery included mitral valve repair, reconstruction of the right ventricular outflow tract, pulmonary valve replacement, and closure of the ventricular septal defect...
