BACKGROUND/AIMS: There is a controversy about the availability of invasive treatment for esophageal/gastric varices in patients with Child-Pugh class C (CP-C) end-stage liver cirrhosis (LC). We have evaluated the validity of invasive treatment with CP-C end-stage LC patients. METHODS: The study enrolled 51 patients with CP-C end-stage LC who had undergone invasive treatment. The treatment modalities included endoscopic variceal ligation in 22 patients, endoscopic injection sclerotherapy in 17 patients, and balloon-occluded retrograde transvenous obliteration (BRTO) in 12 patients. We have investigated the overall survival (OS) rates and risk factors that contributed to death within one year after treatment. RESULTS: The OS rate in all patients at one, three, and five years was 72.6%, 30.2%, and 15.1%, respectively. The OS rate in patients who received endoscopic treatment and the BRTO group at one, three, and five years was 67.6%, 28.2% and 14.1% and 90.0%, 36.0% and 18.0%, respectively. The average of Child-Pugh scores (CPS) from before treatment to one month after variceal treatment significantly improved from 10.53 to 10.02 (P=0.003). Three significant factors that contributed to death within one year after treatment included the presence of bleeding varices, high CPS (≥11), and high serum total bilirubin levels (≥4.0 mg/dL). CONCLUSIONS: The study demonstrated that patients with a CPS of up to 10 and less than 4.0 mg/dL of serum total bilirubin levels may not have a negative impact on prognosis after invasive treatment for esophageal/gastric varices despite their CP-C end-stage LC.

A 71-year-old female, who had diabetes mellitus and chronic renal failure on dialysis, had undergone mitral valve repair and tricuspid valve annuloplasty. Five months after the operation, she suffered from infectious endocarditis and underwent mitral valve replacement. Postoperatively, a total fluid volume of 300 to 600 ml/day was drained from the pericardial tube, and its appearance became milky after the start of oral intake of food. She was diagnosed with chylomediastinum. Despite fasting and total parenteral nutrition for 2 weeks and subcutaneous octreotide administration, the volume of fluid drainage was not reduced. Therefore, we planned lymphangiography treatment with Lipiodol on postoperative day 37. On operation, under local anesthesia, the left inguinal lymph node was punctured under ultrasound guidance, and Lipiodol was injected at a rate of 12 ml/h for 1h. On the next day, the volume of fluid drainage was reduced, and the pericardial tube could be removed 9 days after lymphangiography.

The patient is a 39-year-old-man who had rheumatic heart disease and had undergone mitral and aortic valve replacements with mechanical St. Jude prostheses as well as tricuspid valve repair and a MAZE procedure 17 years previously. He was admitted with ventricular tachycardia (VT) and an implantable cardioverter-defibrillator (ICD) was implanted. Four months later, he was admitted again with VT, and attempts to manage the VT with drugs were not successful. We performed electro-anatomical mapping and ablation for VT by re-median sternotomy. His postoperative course was uneventful. At 15 months after surgery, no recurrence of VT was recognized.

A 76-year-old female was admitted with complaints of dyspnea on exertion and lower leg edema. She had undergone an aortic valve replacement thirty-nine years before and a redo aortic valve replacement and mitral valve replacement twenty-eight years before. She also had hemolytic anemia with jaundice. Echocardiography showed severe paravalvular leakage in the aortic and mitral valves, and a blood flow in the aortic annulus that flows from the aortic side into the left atrium. We diagnosed heart failure and hemolytic anemia due to paravalvular leakage and decided to perform a double-valve replacement for the third time. On operation, after removing the aortic valve through aortotomy, aorto- mitral fibrous continuity was extensively calcified and perforated, and its strength was not enough to sew the prosthetic valve to it. Therefore, we decided to perform the Commando procedure. Aortotomy was extended between the noncoronary aortic sinus and the left coronary aortic sinus until it reached the dome of the left atrium. After the prosthetic mitral valve was excised, annuloplasty of the posterior mitral annulus was performed using a bovine pericardial patch, and the new prosthesis mitral valve was implanted. The anterior part of the annulus corresponding to the aorto-mitral fibrous continuity was reconstructed by sewing the base of a two-tongued triangular bovine pericardial patch to the sewing cuff of the mitral prosthesis. After closing the left atrial ceiling with the posterior patch, the aortic prosthesis was secured to the aortic annulus and the pericardial patch. The anterior patch was used to close the right side of the aortotomy. The postoperative course was uneventful, and postoperative echocardiography revealed no paravalvular leakage.

Objective: The placebo effect can enhance the response to treatment, even in the absence of pharmacological ingredients. One possible factor explaining the likelihood of the placebo effect in individuals is genetic polymorphisms in neurotransmitters. This study focused on gene polymorphisms in the catechol-O-methyltransferase (COMT) as an interindividual variable of the placebo effect.Design・Methods: All 120 participants were explained the effects of caffeine, including its ability to ameliorate drowsiness and increase concentration, and then given a placebo (lactose). The onset of the placebo effect was measured in terms of the degree of caffeine-reduced sleepiness using subjective indices of the Stanford Sleepiness Scale (SSS) and a feeling of drowsiness-Visual Analogue Scale (VAS). The mechanism of the placebo effect was objectively examined in terms of changes in cerebral blood flow in the prefrontal cortex of the brain. In addition, we investigated participants’ susceptibility to the placebo effect by examining genetic polymorphisms in COMT.Results: After taking the drug, sleepiness on the SSS and VAS was significantly improved (p＜0.001), although there was no change in prefrontal cortex activity. Among the 120 participants, 63 had a Val/Val-type polymorphism in COMT (52.5%), 45 had a Val/Met-type (37.5%), and 12 had a Met/Met-type (10.0%). There were no significant differences among COMT gene polymorphisms in the subjective measures of SSS and VAS. However, there was a tendency for the cerebral blood flow changes to be larger in the left hemisphere of the brain in individuals with the Met/Met type.Conclusion: There seems to be a relationship between prefrontal cortex activity and genetic polymorphisms. In particular, there may be a correlation between the expression of a placebo effect and COMT gene polymorphisms.

Mitral valve surgeries for cases with mitral annular calcification (MAC) are challenging because of the operative complications. For a case of MS with MAC, we achieved mitral valve plasty by ultrasonic decalcification alone. An 82-year-old male with edema and dyspnea was diagnosed with AS and MS with MAC. MAC was so severe that MVR was challenging. There were calcifications at the anterior commissure and the anterior mitral leaflet (AML), and removal of them was expected to improve the valve function. Therefore, anterior commissurotomy and ultrasonic decalcification of the anterior commissural annulus was performed using cavitron ultrasonic surgical aspiration (CUSA). Following the resection of the aortic valve, we carried out decalcification of the AML through the aortic valve orifice. After AVR, a trans-esophageal echocardiogram showed MS was ameliorated. Two years after surgery, recurrence of MS was not recognized. Some mitral cases with MAC can be treated by only decalcification to avoid risky valve replacement.
