Purpose: The purpose of this study was to develop an informational leaflet on emergency care and to explore effects of facilitative nurse-patient interaction behavior using an informational leaflet on patient satisfaction with nurse-patient interaction behavior, patient anxiety, and patient satisfaction with use of emergency care. Methods: This study was a quasi-experimental study that applied a nonequivalent control-group posttest-only design. The participants were 81 patients who visited the emergency department of a hospital in Korea; the experimental group (n=40) received facilitative nurse-patient interaction behavior using an informational leaflet, and the control group (n=41) received care under routine protocols without an information leaflet. The effects of the two groups were analyzed using an independent t-test with SPSS computer program. Results: Patient satisfaction with nurse-patient interaction behavior and use of emergency care in the experimental group were significantly higher than in the control group. Patient anxiety related to using emergency care in the experimental group was significantly lower than the control group. Conclusion: Therefore, facilitative nurse-patient interaction behavior using an informational leaflet to the patient may be useful interventions that are easily implemented by nurses in emergency settings.

Objective: This study aimed to explore the readability and comprehensibility of the drug information on a patient leaflet for the senior by employing performance-based user-testing. Methods: We included 36 elderly (65 years old or older) as the senior group (intervention group) and 36 adults (40~59 years old) as the adult group (control). We developed a questionnaire to test if participants could access to drug information. After completing a questionnaire, the participant was interviewed about their understanding over the patient leaflet. We performed t-test, ${\chi}^2$-test or Fisher's exact test to examine differences between two groups in primary outcomes. Results: The senior were less likely able to find information (78%) than the adult (91%); they were much less likely able to understand information (42%) than the adult (69%). While we found differences between the ability of finding and understanding drug information in both groups, the senior group had greater difficulties in understanding all kinds of drug information. They had significant difficulties to remember information after reading the patient leaflet and frequently failed to find proper information even though they were allowed to access freely to the leaflet during interviewing. Conclusion: To secure safe and effective use of drugs for the senior, it is necessary to develop drug leaflets for the senior.

Fracture of prosthetic valve leaflets in the absence of traumatic injury is very rare. Leaflet fracture can cause acute pulmonary edema and cardiogenic shock and is potentially life-threatening, requiring emergency surgery. Thus, a leaflet fracture must be diagnosed quickly and accurately. We present the case of a 46-year-old man with CarboMedics prosthetic aortic and mitral valve replacements implanted 24 years previously. The patient presented at our emergency department with abrupt dyspnea and fever. We diagnosed severe mitral valve regurgitation with anterior leaflet fracture. The patient underwent venoarterial extracorporeal membrane oxygenation and delayed mitral valve replacement. The foreign body was removed step by step because the diagnosis was missed. Two pieces of broken leaflets were found in the left common iliac artery and left external iliac artery. The patient was treated successfully and remains asymptomatic 1 year following surgery.

From January 1962 to March 1987, 97 patients underwent operation for mitral valve disease. Of these patients, 61 [62.9%] required mitral valve replacement. Thirty-six patients [37.1%] had mitral valve repair. The mean age was 26.9*11.6 years [range 5 months to 48 years]. There were 32 [88.9%] cases of rheumatic valve disease, 4 [11.1%] cases of congenital mitral valve disease. Valve dysfunction was classified into three types: type I [normal leaflet motion], 6 patients; type II [prolapsed leaflet], 1 patient; type III [restricted leaflet motion], 29 patients. Twenty-nine patients [80.6%] had pure or predominant stenosis and 7[19.4%] had pure regurgitation. No patient was in NYHA functional class I. Three patients [16.7%] were in functional class II, 15[83.3%] were in functional class II. The techniques used included closed mitral commissurotomy [16 patients], open mitral commissurotomy [13 patients], localized Wooler type annuloplasty [4 patients], suture repair of leaflet defect [3 patients], chordal shortening [1 patient], Carpentier ring annuloplasty [1 patient], and fenestration of fused chordae [1 patient]. There were two perioperative deaths [5.6%], related to left ventricular failure and reoperation. The survivors were followed up for 94 patient-years [mean 4.68*5.54 years]. One late death [1.1*1.1% per patient-year] occurred and was valve related. Reoperation was required in 3 patients, of whom 2 were deaths. There was 1 case [1.1*1.1% per patient-year] of thromboembolism. No patient received anticoagulant after operation. At 10 year, 92*7.4% of the patients were still alive. The actuarial survival rate of patients free of valve-related complication was 79*6.4% at 6 years, 27*12.1% at 11 years. After surgery, 18 patients [88.9%] were in NYHA functional class I or II.

We report a case of leaflet embolization of central leaflet fracture a 31mm mitral Edw-ards-Duromedics prosthesis. A leaflet was fractured to two segments, a larger one embolized to right common iliac artery and a smaller one to left femoral artery, respectively. Patient was reoperated with 29mm mitral Carbomedics prosthesis and incidentally found of smaller segment in left femoral artery at cannulation site. The embolectomy was done 15 days after cardiac operation through midline abdominal incision, Leaflet escape of a mitral Edward-Duromedics prosthesis is a rare, potentially curable mode of valve failure. After mechanical valve replacement, unexplained heart failure and acute pulmonary edema, mechanical valve failure should be suspected. Correct interpretation of clinical signs, symptoms and fluroscopy should allow early diagnosis of leaflet escape and prompt surgical therapy.

Recently, the penetration rate of Magnetic Resonance Imaging (MRI) is higher than the average among OECD member countries, and the number of MRI scans is increasing. However, MRI scans take longer than other medical devices, and patient movement must be minimized. Therefore, patient discomfort always follows. When the examination is performed in the discomfort of the patient, it is difficult to perform an accurate examination, and it is difficult to obtain an image of diagnostic value. So, in the past, the patient was asked to read the written guide for the risk and cooperation of MRI, but it was composed of technical terms and difficult-to-understand sentences, so it was difficult to understand. The purpose of this study is to supplement these problems and increase the understanding of MRI scans to help acquire images of diagnostic value. In addition, it is intended to evaluate the excellence of leaflet education by evaluating the understanding and satisfaction of patients. As shown in the results of this study, understanding and satisfaction scores were higher after education than before leaflet education, and it was found that there was a difference in understanding according to academic background. However, there was no difference in the number of MRI scans. That is, there was no difference in the number of inspections due to leaflet education. In the future, leaflet education will be widely used for MRI examination, and it is necessary to study the qualitative evaluation of images after leaflet education in the future.

Purpose: This study was conducted to investigate how information using leaflet will affect anxiety of inpatients undergoing endoscopic examination. Methods: Non-equivalent control group with a pre-post test design was used. Subjects were selected from inpatients of D hospital in B city for endoscopic examination from May 1 to July 31, 2009. Forty subjects were assigned to either control or experimental group. The Leaflet developed by authors was used as an educational material. Johnson's visual analogue scale, blood pressure, and pulse were used to measure anxiety. Results: The experimental group informed with the leaflet showed less subjective anxiety than control group without the leaflet (p=.008). Experimental group informed with the leaflet showed less objective anxiety measured by systolic blood pressure, diastolic blood pressure, and heart rate than control group without the leaflet (p=.004, .014, and .009, respectively). Conclusion: Giving information using leaflet to the patient before endoscopy may be applicable as a nursing intervention to reduce anxiety. Further studies are needed to generalize the results of this study.

A cleft in the anterior mitral valve leaflet is commonly associated with atrioventricular septal defects, but may occur as an isolated phenomenon. The cleft mitral valve can cause regurgitation, and surgical treatment of the cleft leaflet should conserve the existing valve if possible. But if satisfactory hemodynamic security cannot be obtained with a reconstructive procedure, the valve should be replaced. We present one case of an isolated cleft in the anterior mitral valve leaflet. The patient showed marked mitral regurgitation in the preoperative left ventriculogram. We managed him successfully by interrupted suture repair of the cleft, and he was discharged uneventfully.

Background: Although aortic valve repair can reduce prosthesis-related complications, rheumatic aortic regurgitation (AR) caused by leaflet restriction is a significant risk factor for recurrent AR. In this study, we evaluated the long-term results of the leaflet extension technique for rheumatic AR. Methods: Between 1995 and 2016, 33 patients underwent aortic valve repair using the leaflet extension technique with autologous pericardium for rheumatic pure AR. Twenty patients had severe AR and 9 had combined moderate or greater mitral regurgitation. Their mean age was $32.2{\pm}13.9$ years. The mean follow-up duration was $18.3{\pm}5.8$ years. Results: There were no cases of operative mortality, but postoperative complications occurred in 5 patients. Overall survival at 10 and 20 years was 93.5% and 87.1%, respectively. There were no thromboembolic cerebrovascular events, but 4 late deaths occurred, as well as a bleeding event in 1 patient who was taking warfarin. Twelve patients underwent aortic valve reoperation. The mean interval to reoperation was $13.1{\pm}6.1$ years. Freedom from reoperation at 10 and 20 years was 96.7% and 66.6%, respectively. Conclusion: The long-term results of the leaflet extension technique showed acceptable durability and a low incidence of thromboembolic events and bleeding. The leaflet extension technique may be a good option for young patients with rheumatic AR.

Sliding annuloplasty has been used for mitral valve repair in conjunction with posterior leaflet quadrangular resection to avoid systolic anterior motion of the anterior leaflet of the mitral valve. Herein, we report on a case of successful mitral valve repair with using the annular plication technique to facilitate sliding annuloplasty and extensive quadrangular resection was also done for treating a Marfan's syndrome patient who had an extremely redundant leaflet and a severely dilated annulus.
