Jong Hun Kim, Kyung Hwa Kim, Jong Bum Choi, Ja Hong Kuh
Letter to the Editor We read with great interest the report by Inoue et al. (Cusp-level chordal shortening for non-rheumatic mitralanterior leaflet prolapse in a patient with persistent atrial fibrillation. J Heart Valve Dis 2015;24:586-589) that described their mitral valve repair technique for anterior leaflet prolapse (ALP) and perioperative adaptive servo-ventilation (ASV) therapy for preventing the recurrence of atrial fibrillation after the maze procedure. Latent recurrence of atrial fibrillation after the maze procedure is caused by many factors...

Letter to the Editor Patients with a mechanical heart prosthesis require lifelong anticoagulation to prevent valve thrombosis that could lead to deleterious complications or even death. LMWH protocols have proven feasible and safe in most mechanical prosthesis bearers requiring an interruption of oral anticoagulation because of surgery. However, some patient populations have not been included in trials and might behave differently. To this end, we would like to present the case of a 56-year-old man with mechanical aortic prosthesis treated with bevacizumab...

A novel method is described for artificial chordae replacement with expanded polytetrafluoroethylene suture in mitral valve repair procedures. The technique does not involve knots over or beneath the free edge of the mitral valve leaflets. Artificial chords suspend the exact free margin of leaflets as if it were a continuation of the free margin, such that the smooth zone of the coapting area can be preserved. This technique is simple, reproducible, and applicable to both anterior and posterior leaflets. Moreover, the length of the artificial chords can be adjusted rapidly and accurately at the first attempt...

The case is presented of a non-infectious anterior mitral valve leaflet diverticulum, which appeared as symptomatic mitral stenosis. Unlike previous reports, there was no histological myxomatous degeneration of the valve. To the authors' knowledge, this is the first time a mitral valve diverticulum resulting in severe mitral stenosis has been reported in the literature.

The case is presented of a 72-year-old male patient suffering from active infective aortic prosthetic endocarditis two months after emergency surgery with aortic valve implantation, and who underwent aortic arch reconstruction using a Dacron patch, due to the spontaneous post-procedural migration of a transcatheter-implanted aortic valve. The heart team considered transcatheter valve implantation (TAVI) due to the increased operative risk demonstrated by a EuroSCORE II of 10.9%, including chronic obstructive pulmonary disease (GOLD 3), cirrhosis (Child-B), esophageal varicose stage 2, chronic renal failure stage 3, and reduced left ventricular ejection fraction...

A 59-year-old male with a history of mitral valve replacement several years previously was admitted to the authors' institution with symptoms of advanced heart failure. Echocardiography showed a severe paravalvular dehiscence and surgery was discouraged due to high perioperative risk. A first transcatheter leak closure was unsuccessful despite the correct deployment of various occluding devices. A second percutaneous attempt was carried out with implantation of three Amplatzer Vascular Plug® III devices (five occluders were positioned in total within the oblong defect), leading to a mild residual leakage...

Coronary artery stenosis is a potentially life-threatening complication after heart valve surgery. The details are presented of a patient with unobstructed coronary arteries, who underwent routine aortic valve replacement and developed dissection of the right coronary artery (RCA) on the third postoperative day, and occlusion of the left anterior descending (LAD) artery one month after surgery. This complication required prompt clinical recognition and diagnosis by repeat coronary angiography, and a rapid intervention with coronary artery bypass grafting or with angioplasty and stenting...

Rodney De Palma, Nawsad Saleh, Andreas Ruck, Magnus Settergren
Percutaneous valve implantation is a recognized therapy for calcific aortic stenosis in those patients who are inoperable or at high surgical risk. The transfemoral approach is the most frequently used method for device delivery, but a tortuous calcific aorta and the inflexibility of large-caliber endovascular equipment can impede progress or even cause the procedure to be abandoned. Herein, the use of a technique employing a snare to safely overcome device obstruction in the aortic arch of an elderly female patient is described...

Transcatheter aortic valve implantation (TAVI) is an emerging treatment for high-risk patients with aortic stenosis. Aortic regurgitation is considered to be a relative contraindication for transcatheter procedures, as a non-calcified aortic annulus poses the risk of an insufficient anchoring of the transcatheter aortic valve prosthesis. Herein is described the case of a patient who suffered from recurrent aortic valve regurgitation after valve-sparing repair, and which was successfully treated by the transcatheter implantation of an Edwards SAPIEN 3™ prosthesis...

BACKGROUND: Despite being usually clinically silent, paravalvular leak can present with congestive heart failure (CHF) or haemolytic anemia. Here, the case is reported of a paravalvular leak presenting with CHF, complicated by new-onset severe hemolytic anemia after percutaneous closure with a large ventricular septal duct (VSD) occlude device. METHODS: A 57-year-old patient presented with infectious endocarditis of a native mitral valve with major mitral regurgitation and was submitted for mitral valvuloplasty...

Transcatheter aortic valve replacement (TAVR) is used for the treatment of aortic stenosis (AS). Besides major bleeding, conduction blocks, stroke or atrial fibrillation, complications include cardiac perforation with possible left-to-right-shunts. Herein is reported the sixth case of a left-to-right shunt in an 87-year-old man who underwent TAVR using a 29 mm Edwards SAPIEN S3 prosthesis to treat AS. Soon after the procedure, a small channel evolving from the right coronary cusp could be detected on echocardiography...

BACKGROUND: The study aim was to evaluate the outcomes of minimally invasive valve surgery, performed via a right anterior thoracotomy approach, in patients with a history of multiple (more than two) prior cardiac surgeries. METHODS: A retrospective review was conducted of all minimally invasive valve operations performed in patients with a prior history of two or more cardiac surgeries, including coronary artery bypass grafting (CABG) and/or valve surgery, at the authors' institution between January 2008 and November 2014...

Jong Hun Kim, Tae Youn Kim, Jong Bum Choi, Ja Hong Kuh
In adult patients who have undergone mitral annuloplasty with a rigid ring at a young age, the mitral valve may ultimately deform and demonstrate insufficient growth because the valve annulus is fixed to the ring. Mitral valve re-repair, following this scenario, was performed for mitral stenoinsufficiency in a 26-year-old female patient who had undergone mitral annuloplasty with a rigid ring at the age of five years. The valve re-repair procedure consisted of decalcification and stripping of the anterior leaflet and annulus, posterior leaflet augmentation using an elliptical autologous pericardial patch, and a posterior strip annuloplasty sparing the anterior annulus and commissures...

BACKGROUND: Functional mitral regurgitation (FMR) is common in patients with advanced heart failure and impaired left ventricular function. The study aim was to examine functional and hemodynamic effects at three months after MitraClip® implantation in high-risk surgical patients with FMR. METHODS: A group of 93 patients was rejected for surgical treatment by heart-team decisions due to an inacceptable risk for conventional mitral valve surgery. Between October 2011 and May 2015, 89 of these patients (96%) were treated successfully with MitraClip implantation...

Mitral valve diseases (MVD)s, comprising congenital and acquired forms, are characterized by a diverse etiology, pathophysiology, prevalence, and incidence. In industrialized countries, the acquired forms represent 2.5% of all cardiovascular diseases, with a marked augmentation after the age of 65 years. In addition, all forms of MVDs (i.e., degenerative forms) have a difficult clinical management. The major challenge is 'the early diagnosis', and echocardiographic analysis has been shown inappropriate for diagnosing MVD in moderate forms...

Left ventricular pseudoaneurysm (LVPA) after mitral valve replacement (MVR) is a rare condition. The diagnosis of LVPA may be difficult, and for accurate diagnosis, two-dimensional (2D) transthoracic echocardiography (TTE) should be used in combination with other imaging modalities such as multiple detector computed tomography (MDCT) and three-dimensional (3D) TTE. Herein is presented a late type of post-MVR pseudoaneurysm in a 72-year-old female who was admitted to the authors' emergency department with complaints of dyspnea...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

BACKGROUND: The study aim was to evaluate the long-term clinical outcomes of the modified Bentall procedure (MBP) with a mechanical conduit. METHODS: Between 1993 and 2014, a total of 249 patients (mean age 62 ± 12 years; range: 25-87 years) underwent a MBP at the authors' institution. The main indication was annuloaortic ectasia in 102 patients (41%), followed by acute aortic dissection in 82 patients (33%); moderate to severe aortic regurgitation was present in 79% of cases...

BACKGROUND: The management of graft infection following ascending aortic replacement (AAR) and/or aortic valve replacement (AVR) with destruction of the root remains a challenge. Besides technical issues, the choice of graft material is controversial. The study aim was to investigate the initial results of aortic root replacement (ARR) as redo-surgery for infection using the xenopericardial all-biologic conduit (BioIntegral) as an alternative to a homograft or prosthetic material. METHODS: Between February 2013 and January 2015, a total of 18 consecutive patients (16 males, two females; mean age 61 ± 14 years) were reoperated on for infection at a mean of 55 ± 61 months (range: 3 to 219 months) following previous AVR (n = 6), supracoronary aortic replacement (SAR, n = 2), AVR + SAR (n = 1), root replacement (n = 7), and root reconstruction (n = 2)...

A 70-year-old woman with a history of aortic valve replacement and coronary artery bypass grafting (CABG) was transferred to the authors' hospital for further management of a three-month fever of unknown origin. Computed tomography showed a huge mass in the ascending aorta with pseudoaneurysm. Blood β-D-glucan levels were significantly high, and blood culture showed the growth of Candida albicans. The fungus ball was excised surgically, together with aortic root replacement and CABG, followed by six-month postoperative anti-fungal therapy...
