The use of artificial polytetrafluoroethylene (PTFE) chordae has been widely adopted in the setting of mitral valve repair. In this tutorial, we present a modified technique for neochordae placement using a semi-rigid complete ring, with a chordal sizing system. This ring was introduced with the aim of standardizing neo-chordae implantation and we introduce a modification of the implantation technique in the presence of myxomatous leaflets.

Mitral valve repair is becoming an increasingly frequent surgery for patients with mitral valve regurgitation. Iatrogenic coronary artery injury and ischemic myocardial compromise have been previously reported in the literature as a rare but serious complication of surgical mitral valve repair. This potentially life-threatening complication should be considered and quickly recognized during perioperative mitral valve repair or replacement to prevent morbidity and mortality. To increase awareness and to prevent this complication from being missed in the future, we present a case report of iatrogenic left circumflex artery dynamic occlusion and subsequent myocardial infarction from mitral valve annuloplasty resulting in severe peri-operative heart failure and death...

BACKGROUND: The patho-etiology of mitral regurgitation (MR) has been suggested as a mediator of outcomes following mitral valve (MV) operations, particularly in ischemic functional mitral regurgitation (IMR). This study examined the independent association of MV etiology with mortality. METHODS: Using the Society of Thoracic Surgeons Database, all patients undergoing mitral valve replacement or repair from 2011-2014 were assessed. Patients who underwent concomitant surgical ablation, septal defect closure, tricuspid valve repair, or coronary artery bypass grafting were included...

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term "cardiac surgery". This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier...

BACKGROUND: Cardiac surgery for myelodysplastic syndrome (MDS) patients is challenging because anemia and neutropenia develop as a result of the syndrome, leading to infection and bleeding tendency during surgery. We report the case of minimally invasive mitral valve repair via a right mini-thoracotomy and perioperative use of granulocyte colony-stimulating factor (G-CSF) in a patient with MDS. CASE PRESENTATION: A 77-year-old man with myelodysplastic syndrome (MDS) was referred for surgical treatment for mitral valve regurgitation and underwent a minimally invasive mitral valve repair via a right mini-thoracotomy (MICS mitral procedure)...

PURPOSE OF REVIEW: Analyze the current state of the art and the future perspectives of mitral interventions in clinical setting. RECENT FINDINGS: A systematic and critical review of the new mitral percutaneous therapies and imaging technologies is the basis to adopt the right treatment for each patient according to specific valve dysfunction and clinical presentation, waiting for definitive guidelines. While surgical mitral repair will remain the gold standard for low-risk healthy patients with degenerative mitral regurgitation (DMR), transcatheter mitral valve repair is becoming first line therapy in high risk patients with functional mitral regurgitation (FMR)...

Functional ischemic mitral regurgitation is strongly associated with poor outcomes in patient with coronary artery disease. The best management for mitral regurgitation at the time of coronary revascularization remains controversial. We report, a case of 58 years-old men admitted to GKNM hospital, Coimbatore, Tamil Nadu, India with chest pain and respiratory distress for last 6 hours during my fellowship training in that hospital. ECG showed acute antero-septal MI. The transthoracic echocardiogram revealed severe left ventricular dysfunction with moderate mitral regurgitation...

A 36-year-old pregnant woman with a history of rheumatic heart disease and prior aortic valve replacement and mitral valve repair presented to an outside hospital with severe aortic stenosis. The patient had a cardiac arrest upon labor induction and underwent a transcatheter aortic valve replacement (TAVR), which dislodged two days later. Five months later, the patient underwent removal of the dislodged TAVR and a Ross procedure at the authors' institution. The patient was stable upon discharge, with minimal aortic and pulmonary regurgitation...

The case is described of a successful MitraClip procedure performed on an 88-year-old patient with severe mitral regurgitation (MR), five years after she had undergone mitral valve repair using the Alfieri surgical procedure. It is suggested that the MitraClip procedure is an option in patients with severe MR persisting after the Alfieri procedure. Video 1: Transesophageal echocardiography before the MitraClip procedure. Severe mitral regurgitation with preserved left ventricular systolic function. The main regurgitant jet originates from the medial commissure...

A 79-year-old woman with a history of ischemic dilated cardiomyopathy, severely depressed left ventricular ejection fraction and significant mitral regurgitation (MR) was admitted to the authors´ institution for percutaneous mitral valve repair. Transesophageal echocardiography (TEE) revealed the presence of a posterior mitral cleft at the P2 level, causing a trileaflet mitral valve that contributed significantly to the regurgitant jet. The procedure was performed under general anesthesia and guided by real-time three-dimensional TEE...

BACKGROUND: Myxomatous mitral valve disease (MMVD) is one of the most prevalent valvular heart diseases, while back pain, neck pain and upper-extremity numbness are some of the most common complaints in outpatient settings. Decreased thoracic kyphosis (straight back) is a known cause of hastening back or neck problems, radiculopathy, or even myelopathy. The study aim was to examine the relationship between MMVD, straight back, and the need for cervical fusion. METHODS: In this single-center retrospective study, patients who underwent mitral valve repair or replacement due to MMVD (cases) based on age, gender and body mass index (BMI), were matched with patients who underwent coronary artery bypass grafting (CABG) surgery and had no history of mitral valve disease (controls)...

BACKGROUND: Segmental analysis of diseased mitral valves is important to predict a successful surgical valve repair. An assessment was made of the comparative accuracy of intraoperative three-dimensional (3D) and two-dimensional (2D) transesophageal echocardiography (TEE) in the evaluation of mitral valve lesions when compared with intraoperative surgical segmental analysis. METHODS: A total of 42 consecutive patients (12 females, 30 males; mean age 70.5 ± 14 years) with severe mitral valve regurgitation due to degenerative disease and who underwent mitral valve repair was enrolled in the study...

OBJECTIVES: With the emergence of transcatheter mitral valve-in-valve/ring replacement for deteriorated bioprostheses or failed repair, comparative clinical benchmarks for surgical repeat mitral valve replacement (re-MVR) are needed. We present in-hospital and survival outcomes of a 24-year experience with re-MVR. METHODS: From January 1992 to June 2015, 520 adult patients underwent re-MVR; 273 had undergone prior mitral valve repair (pMVP) and 247 had undergone prior MVR (pMVR)...

Limited data exist on the occurrence of acute kidney injury (AKI) associated with percutaneous mitral valve repair (PMVR). The objectives of the present study were (1) to assess the prevalence of AKI after MitraClip (Abbott Vascular, Santa Clara, California) implantation, (2) to analyze the predictive factors of AKI, and (3) to evaluate the prognostic value of AKI after PMVR with a view to optimizing the management of high-risk patients. A total of 206 patients (serum creatinine [SCr] 1.3 ± 0.6 mg/dl, estimated glomerular filtration rate 55 ± 24 ml/min) who underwent PMVR were included...

Background: Anderson-Fabry disease is an X-linked inherited disease, which manifests in a different manner depending on gender and genotype. Making a working diagnosis of Anderson-Fabry disease is difficult because of several reasons: (a) that it is a multiorgan disease with wide variety of phenotypes, (b) different timelines of presentation, (c) gender differences, and (d) possible coexistence with other comorbidities. Late-onset/cardiac type of presentation with minimal involvement of other organs can additionally make diagnosis difficult...

A 47-year-old woman with a history of radiation enteritis and implantation of a central venous port was admitted to our intensive care unit(ICU) suffering from high fever. She was diagnosed with active infective endocarditis due to catheter-related blood stream infection. Although echocardiography showed a large vegetation on the mitral valve, surgical therapy was postponed for 5 weeks because of intracranial hemorrhage infarction. On the 3rd day after mitral valve repair, she developed consciousness disturbance and computed tomography(CT) revealed acute subdural hematoma of the posterior cranial fossa...

A rare case of mitral stenosis after mitral valve repair for non-rheumatic mitral regurgitation is presented. An 81-year-old woman who had undergone mitral valve repair using an annuloplasty ring 12 years earlier, was referred to our hospital because of dyspnea during exertion. As echocardiography revealed severe mitral stenosis, and redo surgery was carried out. During the surgery, fibrous tissue covered the annuloplasty ring and extended onto both leaflets of the mitral valve, which narrowed its orifice, by rendering the leaflets stiff and immobile...

BACKGROUND: Septal myectomy has been the mainstay of the surgical treatment of obstructive hypertrophic cardiomyopathy (HCM), however recently there is growing appreciation for associated mitral valve abnormalities that contribute to left ventricular outflow tract (LVOT) obstruction. In this study, we describe our experience with combined papillary muscle realignment (PMR) and septal myectomy for the treatment of obstructive HCM. METHODS: We identified 44 patients undergoing surgery for obstructive HCM whose anatomy was amenable to combined PMR and septal myectomy at our institution over a 20-month period...
