Patient with aortic valvular disease have increased left ventricular work and greater myocardial oxygen demand, which may aggravate the effect of concomitant coronary artery disease. Thus in patient who repair aortic valve replacement, concomitant aortocoronary bypass surgery is often performed when angiographically significant coronary artery disease is present. This approach is supported by reports that revascularization does not increase operative risk when associated coronary artery disease is present and significantly reduce the occurrence of late sudden death. Recently we have experienced one case of aortic valve replacement concomitant with aorta-coronary bypass surgery. The patient was 56 year-old male and admitted with complaint of anterior chest pain especially during his exercise. He was diagnosed as aortic valve stenosis and regurgitation [GIII] with proximal right main coronary artery occlusion We performed aortic valve replacement with aorta coronary bypass surgery by use of saphenous vein. Post operative course was uneventful and chest pain was relieved. Post operative coronary angiogram disclosed good patency of grafted vessel.

We experienced a case of ruptured aneurysm of the sinus of Valsalva, and this resulted in simultaneous aortic and tricuspid valve endocarditis through a shunt. The echocardiography showed a ruptured sinus of Valsalva aneurysm to the right atrium with a shunt. The aortic non-coronary cusp was fibro-thickened with vegetation. Vegetations of the septal leaflet and the anterior leaflet of the tricuspid valve were also found. The blood culture grew Enterococcus garllinarum. We replaced both tricuspid and aortic valve with successful surgical result.

We report the case of a patient with mitral regurgitation complicated by type B dissection and Marfan syndrome (MFS) who was managed successfully with minimally invasive mitral valve repair. Without type A aortic dissection or aortic root dilation, MFS patients may develop mitral valve regurgitation, as in this case, and need valve surgery to improve their symptoms and long-term survival. However, it is not clear that a full sternotomy and prophylactic aortic surgery are necessary. Although retrograde perfusion to the dissected aorta is controversial, our approach minimizes the risk of future anticipated aortic surgery in MFS patients.

A 11 year-old girl with quadricuspid aortic avlve associated with regurgitation left superior vena cava and chromosomal anomaly is presented. The quadricuspid valve was unexpectedly found during operation for aortic valve replacement. The aortic valve consisted of 4 equal-sized cusps and retrospective review of the aortogram revealed the aortic valve to have 4 cusps also. To the best of our knowledge, this combination of anomalies has not been reported in Korea previously.

Background: The continuous suture (CS) technique has several advantages as a method for simple, fast, and secure aortic valve replacement (AVR). We used a simple CS technique without the use of a pledget for AVR and evaluated the surgical outcomes. Materials and Methods: Between October 2007 and 2012, 123 patients with aortic valve disease underwent AVR alone (n=28) or with other concomitant cardiac procedures (n=95), such as mitral, tricuspid, or aortic surgery. The patients were divided into two groups: the interrupted suture (IS) group (n=47), in which the conventional IS technique was used, and the CS group (n=76), in which the simple CS technique was used. Results: There were two hospital deaths (1.6%), which were not related to the suture technique. There were no significant differences in cardiopulmonary bypass time or aortic cross-clamp time between the two groups for AVR alone or AVR with concomitant cardiac procedures. In the IS group, two patients had prosthetic endocarditis and one patient experienced significant perivalvular leak. These patients underwent reoperations. In the CS group, there were no complications related to the surgery. Postoperatively, the two groups had similar aortic valve gradients. Conclusion: The simple CS method is useful and secure for AVR in patients with aortic valve disease, and it may minimize surgical complications, as neither pledgets nor braided sutures are used.

Extensive mitral annulus calcifications are considered a contraindication for valve surgery. We describe the case of a 76-year-old female with severe mitral and aortic stenosis associated with extensive calcifications of the heart. The patient underwent an open mitroaortic valve replacement using transcatheter aortic valve implantation with an Edwards SAPIEN XT valve (Edwards Lifesciences Corp., Irvine, CA, USA) in the mitral position. The aortic valve was replaced using a stentless valve prosthesis (LivaNova S OLO; LivaNova PLC, London, UK). Postoperative echocardiography showed that the prosthetic valve was in the correct position and there were no paravalvular leaks. A bailout open transcatheter valve implantation can be considered a safe and effective option in selected cases with an extensively calcified mitral valve.

Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder that is characterized by aggressive arterial and aortic disease, often involving the formation of aortic aneurysms. We describe the cases of two children with LDS who were diagnosed with aortic root aneurysms and successfully treated by valve-sparing aortic root replacement (VSRR) with a Valsalva graft. VSRR is a safe and suitable operation for children that avoids prosthetic valve replacement.

We compared between prosthetic aortic valve size and aortic annulus size in supravalvular aortic cineangiogram in 30` RAO view postoperatively. Retrospectively, supraaortic cineangiogram of 27 patients among the patients underwent aortic valve replacement only or double valve replacement from April, 1986 to January, 1987 was examined and measured the aortic annulus size. In comparing the two values, the cases within 1mm is 22, and the cases within 2mm is 25, correlation coefficient yield r = 0.92. In two cases, the difference between two values is within 3mm We concluded that to prevent the complication from mismatching the prosthetic aortic valve size to patient`s annulus size [e.g. left ventricular failure, hemolysis, limited exercise tolerance], prediction of the prosthetic valve size preoperatively by use of cineangiogram is useful.

Although it is attractive, a limitation of aortic valve (AV) replacement (AVR) through a mini-thoracotomy approach (mini-AVR) is the limited exposure of the AV. Here, we present a simple exposure technique named "suspending commissural sutures" for a more efficient mini-AVR. The technique involves making 3 half-depth stitches with 1-0 silk at each of the commissures, which are anchored to each corresponding pericardial surface. These stitches are tightened up so that the aortic root is axially expanded and is pulled upward. The technique of suspending commissural stitches seems to offer reasonable exposure of the AV in mini-AVR, and shows excellent early surgical outcomes.

We present 2 cases of patients who underwent surgical repair and replacement of an injured aortic valve that was secondary to nonpenetrating trauma. Primary repair was undertaken on an 18-year old boy, but he had persistent moderate aortic regurgitation for five years after surgery. Another 64-year old man was treated successfully with surgical replacement of the aortic valve via employing a prosthetic mechanical valve. Attempts at valvuloplasty for the treatment of traumatic aortic valve injury have not been uniformly successful, and prosthetic valve replacement is recommended for repair, except for highly selected cases.
