ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Favipiravir is a promising treatment candidate for managing coronavirus disease 2019 (COVID-19). Warfarin has many drug interactions, but no interactions with favipiravir have been reported. CASE SUMMARY: Our patient was taking warfarin for deep vein thrombosis. The international normalized ratio (INR) was stable (1.65 to 2.0); however, it increased to 4.63 after administering favipiravir. The patient had no other factors justifying this change. WHAT IS NEW AND CONCLUSION: Favipiravir and warfarin might have previously unidentified drug interactions that elevated the INR. Therefore, INR must be closely monitored when they are concomitantly administered in COVID-19 patients.

ABSTRACT

The frozen elephant trunk (FET) procedure enables easier replacement of the entire aortic arch because it does not require reaching the distal part of the left subclavian artery (LSCA). However, it requires additional management for reconstruction of the LSCA, which is associated with bleeding events. However, the fenestrated FET technique confers a risk of endoleakage from the fenestration site. We report our unique novel technique in which the proximal side of the hybrid stent graft is cut into V-shape around the subclavian artery and sutured continuously around the orifice of the subclavian artery during aortic stump fixation.

ABSTRACT

Uterine leiomyosarcoma is a malignant soft tissue tumor resembling uterine fibroma clinically and is difficult to diagnose preoperatively. Since metastatic cardiac tumors are very rare and asymptomatic, most cardiac metastases are detected at autopsy after death due to other diseases. A 49-year-old woman presented with menorrhagia and anemia, and a uterine tumor. Total hysterectomy was performed for the uterine tumor. Histopathological examination revealed the tumor to be a leiomyosarcoma. Postoperative computed tomography showed multiple lung metastases and a metastatic cardiac tumor. The cardiac tumor, which was located within and almost entirely occluded the right ventricle, was 49 × 26 mm. To prevent sudden death, cardiac tumorectomy was performed semi-emergently. Chemotherapy was initiated in the early postoperative period, and the patient currently maintains a complete response. Cases with lung and cardiac metastases rarely undergo surgical resection of metastatic tumors. However, emergent surgical resection of cardiac metastatic tumors should be considered to prevent sudden death.

ABSTRACT

OBJECTIVE: We previously reported a unique technique called "less invasive quick replacement (LIQR)" for treating type A acute aortic dissection with moderate hypothermic arrest (28 °C). This study examines the modified LIQR using mild hypothermic arrest (30 °C) with partial retrograde cerebral perfusion (RCP). METHODS: 187 patients were divided into 2 groups: group L consisted of 130 patients underwent LIQR without any cerebral perfusion; group M consisted of 57 patients who were treated with modified LIQR. In modified LIQR, circulatory arrest was commenced under the 30 °C for open distal aortic stamp fixation. RCP was used during final half anastomosis of the prosthesis and then rapid re-warming was initiated. RESULTS: The incidence of additional valve or coronary surgeries was significantly higher in group M (28.1%) than in group L (9.2%). The average rectal temperature was significantly higher in group M (29.5 °C) than in group L (27.4 °C). The durations of brain ischemia (M 7.7 min; L 18.6 min), cardiopulmonary bypass (M 82.0 min; L 93.3 min), and overall operation (M 145.2 min; L 154.2 min) were significantly shorter in group M. The incidence of postoperative brain damage was 6 patients (4.6%) in group L, but none in group M. The hospital mortality rate was 3 patients in group L (2.3%). All group M patients were discharged from the hospital without any complications. CONCLUSION: Modified LIQR is safe and effective. It makes the surgery much quicker and is a less invasive procedure. The surgical outcome was also favorable.

ABSTRACT

OBJECTIVE: We assessed the efficacy of distal limited open stenting procedure in octogenarians with distal aortic arch aneurysm. METHODS: During the last 5 years, 24 patients underwent distal limited open stenting. Mean patient age was 81.6 ± 2.5 years, ranging from 80 to 90 years. The hemicircumference of the anterior surface of the arch around the left common carotid artery was obliquely incised, and a J-Graft Open Stent (Japan Lifeline Co, Ltd, Tokyo, Japan) was inserted into the descending aorta. During open stenting, circulatory arrest was induced at a rectal temperature of 28°C without any cerebral perfusion. As soon as the proximal side of the stent graft and aortic incision were concomitantly sutured, rapid rewarming was initiated through heated blood perfusion. RESULTS: The durations of circulatory arrest, aortic crossclamping, cardiopulmonary bypass, the overall operation, postoperative mechanical ventilation, and hospital stay were 17.0 minutes, 27.8 minutes, 106.1 minutes, 167.6 minutes, 11.0 hours, and 13.9 days, respectively. The in-hospital mortality was 0%. There were no incidences of brain damage, renal failure, or respiratory failure. At the time of this study, 21 patients were doing well and visiting the outpatient clinic, and 19 scored more than 20 points on the Mini-Mental State Examination, indicating no development of dementia. The actuarial survival at 5 years was 82.4%. CONCLUSIONS: This unique technique is safe and effective. It is a very attractive procedure that can contribute to maintaining a good long-term quality of life for octogenarians with distal aortic arch aneurysm.

ABSTRACT

A 79-year-old man underwent bifurcated graft replacement for abdominal aortic aneurysm, but the graft was totally occluded owing to an acute type B aortic dissection. We could not have access to the root for performing endovascular stenting for dissecting aneurysm. Furthermore, it was difficult to remove the aneurysm via a left thoracotomy because it was impossible to perfuse the lower body with blood from the femoral artery and also a left axillary arterial cannulation was unusable. Herein, we report a patient who was successfully treated with open surgical aortic stenting for an enlarged ulcer-like projection complicated by a type B aortic dissection.

ABSTRACT

PURPOSE: We investigated the effectiveness of active renin-angiotensin-aldosterone system (RAAS) control with human atrial natriuretic peptide (hANP) and an angiotensin II receptor blocker (ARB) in patients with chronic kidney disease (CKD) undergoing coronary artery bypass grafting (CABG). METHODS: A total of 286 consecutive patients with CKD undergoing CABG were divided into three groups: Group C (n = 50) receiving placebo, the hANP group (n = 60) receiving hANP, and the active RAAS control therapy (ARC) group (n = 56) receiving hANP plus an ARB. Renal function, brain natriuretic peptide (BNP) and RAAS parameters were analyzed. RESULTS: After 1 year, renal function parameters were better in the hANP and ARC groups compared with group C, and the dialysis rate was significantly lower (group C: 12%, hANP group: 1.7%, ARC group: 1.8%, p = 0.018) in the hANP and ARC groups. BNP levels were significantly lower in the hANP and ARC groups compared with group C (p = 0.001). There was also a significant difference of aldosterone among the groups (p = 0.023), as well as a significant difference between group C and the ARC group (p = 0.017). CONCLUSIONS: The present study showed that active RAAS control preserved renal function in patients with CKD undergoing CABG. The improved early postoperative outcome with RAAS control may lead to long-term inhibition of cardiovascular events.

ABSTRACT

OBJECTIVE: We assessed the efficacy of limited proximal arch replacement for type A acute aortic dissection (AAD) with critical complications. METHODS: Sixty-four patients with average age of 64.5 ± 13.0 years, who were intubated prior to arriving at hospital due to cardiopulmonary arrest, cardiac tamponade, or vital organ mal-perfusion, were divided into two groups: group PA consisted of 52 patients undergoing proximal arch repair with mild hypothermic circulatory arrest; group TA consisted of 12 patients who underwent total arch replacement with moderate hypothermia and selective cerebral perfusion. RESULTS: The intimal tear on the distal side of the left subclavian artery was not excised in 11 patients (21.2 %) of group PA. The intimal tear was excised in all patients in group TA. The durations of cerebral protection (PA, 18.7; TA, 70.3 min), cardiopulmonary bypass (PA, 121.5; TA, 206 min), and overall operation (PA, 181.8; TA, 403.8 min) were significantly shorter in group PA. The incidence of postoperative brain damage was significantly lower in group PA (9.6 %) than in group TA (33.3 %). The mortality rate was significantly lower in group PA (5.8 %) than in group TA (58.3 %). Distal arch to descending aortic replacement was required in four patients of group PA during follow-up period. There were no complications or mortality during the reoperation. The actuarial survival rate at 10 years was significantly better in group PA (66.5 %) than in group TA (25 %). CONCLUSION: Limited proximal arch repair is suitable for high-risk patients with AAD, despite no excision of the intimal tear.

ABSTRACT

OBJECTIVES: Open stent grafting for extended aortic repair has been widely carried out around their world. We reported the effectiveness of a new device as an open stent graft for extended aortic repair. METHODS: A new device was used as an open stent graft in this study. The graft part of the device has a woven structure made of Nitinol wire, a superelastic/shape-memory alloy. The subjects of this study were patients aged 20-84 with aneurysms (n = 38) or aortic dissection (n = 22) in the thoracic aorta, including the distal aortic arch and the proximal descending aorta. This study was a multicentre, non-blinded study. The follow-up period was 36 months. RESULTS: Three subjects (5.0%) died during hospitalization due to multiorgan failure. Spinal cord injury (SCI) was observed in 4 subjects (6.7%): paraplegia in 1 and paraparesis in 3 subjects. The 3-year survival rate was 76.7% overall: 68.4% for the subjects diagnosed as having aortic aneurysms (the aortic aneurysm group) and 90.9% for those having aortic dissection (the aortic dissection group). For the aortic aneurysm group, thrombus formation in the aortic aneurysm was observed in 97% of the patients 6 months after operation, and in 100% 12 months after operation. Meanwhile, for the aortic dissection group, with regard to the false lumen of aortic dissection, thrombus formation was observed in 94% of the patients 6 months after operation, in 94% 12 months after operation and in 100% 24 months after operation. Expansion of the aortic aneurysm sac was observed in 2 subjects (6.1%). Among these 2 subjects, endoleak was observed in 1 subject, which was improved by additional thoracic endovascular aortic repair. CONCLUSIONS: The safety and effectiveness of this investigational device was verified over a period up to 36 months after operation. A long-term follow-up would be necessary to further verify the effectiveness of the device in the future.

ABSTRACT

A new device of aortic stent graft made in Japan has been available since July 2014. Here, we describe a novel, unique surgical technique named "less invasive quick open stenting" at a rectal temperature of 28°C without any cerebral perfusion for treating distal arch aneurysms. All 12 patients were discharged from the intensive care unit within 24 hours after surgery without any complications. This technique aids in the exclusion of atherosclerotic plaques on the aortic wall and shortens the duration of circulatory arrest; moreover, it represents a very attractive option to prevent recurrent nerve injury.

ABSTRACT

We assessed the midterm outcomes of 2 types of open surgical repair for type B dissecting aortic aneurysm (BDA). During the last 4 years, 86 patients with BDA (mean age, 68.5 ± 9.8 years; range: 41-87 years) underwent open repair. The average duration between the dissection onset and surgery was 51.5 ± 31.3 months. If the BDA was of open type with patent false lumen or the aneurysm extended for a long segment, descending or thoracoabdominal aortic repair was performed with left thoracotomy. If the BDA was of the closed type with thrombosed false lumen and the aneurysm was located around the distal arch, open stent implantation was performed with our unique technique using circulatory arrest with a rectal temperature of 28 °C without any cerebral perfusion. Left thoracotomy was performed in 68 patients. The durations of aortic clamping and cardiopulmonary bypass were 65.2 ± 16.9 and 78.5 ± 34.6 minutes, respectively. Open stent implantation was performed in 18 patients. The durations of circulatory arrest and cardiopulmonary bypass were 19.1 ± 5.1 and 86.2 ± 17.8 minutes, respectively. In the present study, 4 patients (4.7%) required reexploration for bleeding and 1 patient (1.2%) had a stroke, but none suffered paraplegia. The hospital mortality rate was 1.2% (1 patient), resulting from retrograde type A dissection. The actuarial aortic event-free survival rate, including operative death, was 96.4% at 3 years. Both open surgical procedures for BDA were relatively safe, with favorable early and midterm outcomes, and may be superior for avoiding neurologic complications.

ABSTRACT

OBJECTIVES: The US Food and Drug Administration has suggested that proton pump inhibitors (PPIs) increase the international normalized ratio (INR) when used concomitantly with warfarin (WF) because of being metabolized by cytochrome P450 2C19 (CYP2C19). We assessed whether CYP2C19 genotypes and type of PPI accentuated the drug interaction. METHODS AND RESULTS: The study group was 82 patients who needed WF after surgery and had their CYP2C19 genotypes analyzed in advance. We randomly divided them into two groups: group I (n = 41) included patients who had lansoprazole 15 mg/day and group II (n = 41) included patients who had rabeprazole 10 mg/day. The dose of WF was controlled by the doctor in charge as a target INR of 1.6 to 2.6 during the 2 months after surgery. The maximum INR was significantly higher in group I (3.36 ± 0.98) than in group II (2.29 ± 0.55, p < 0.0001). The incidence of over-INR (> 3.5) was significantly higher in group I (15 cases) than in group II (2 cases, p = 0.0001). Several bleeding events complicated 10 patients in group I, but none in group II (p = 0.015). Logistic regression analysis revealed that over-INR (odds ratio [OR] 3.58, 95% confidence interval [CI]: 3.48-368.25, p < 0.0001), and pair of lansoprazole and CYP2C19 intermediate metabolizer (OR 2.39, 95% CI: 1.108-29.491, p = 0.0009) were independent predictors of bleeding events. CONCLUSION: If a patient has had the intermediate metabolizer CYP2C19 genotype and concomitant use of WF and a PPI after open heart surgery, lansoprazole intensifies the effects of WF and is associated with bleeding events.

ABSTRACT

AIM: This subanalysis aimed to clarify whether intensive lipid-lowering therapy with statins slows the progression of atherosclerosis in Japanese subjects under treatment for primary prevention of cardiovascular disease. METHODS: This was a subanalysis of the Justification for Atherosclerosis Regression Treatment (JART) Study. We compared the efficacy of intensive lipid-lowering therapy and conventional therapy with respect to changes in the mean intima-media thickness (IMT) and serum lipid levels. We also evaluated changes in the mean IMT over 24 months of treatment and assessed the relationship between these changes and reductions in the LDL-C levels using a post-hoc analysis. RESULTS: Intensive lipid-lowering therapy with rosuvastatin was associated with significantly smaller changes in the mean IMT and a greater reduction in the serum lipid levels in comparison to conventional therapy with pravastatin. The average net change in the mean IMT was 0.010 mm (n=121) at 12 months and -0.004 mm (n=56) at 24 months. A decrease in LDL-C was found to be associated with a smaller change in the mean IMT (p=0.0009; Jonckheere-Terpstra trend test). A greater reduction in serum LDL-C was found to be associated with a smaller change in the mean IMT. Similar associations were observed for the serum TC and non-HDL-C levels and LDL-C/HDL-C ratio. There were no notable differences in the incidence of serious adverse events among the LDL-C quartiles. CONCLUSIONS: Lowering the LDL-C level with intensive lipid-lowering therapy is associated with reduced changes in the IMT among Japanese subjects at moderate to high risk under treatment for primary prevention. Subjects suitable for primary prevention may receive cardiovascular benefits from intensive lipid-lowering therapy, in association with significantly slower IMT progression than that observed with conventional therapy.

ABSTRACT

Carotid intima-media thickness (IMT), a measure of atherosclerosis, is modulated by multiple risk factors. Accordingly, comprehensive control of risk factors is indispensable for management of atherosclerosis. In this study, as a posthoc analysis of the JART Study we planned two analyses. In the main analysis, we evaluated the effect of intensive lipid-lowering therapy with rosuvastatin on carotid IMT in high-risk patients. We also evaluated efficacy in the presence or absence of each risk factor using the full analysis population in the JART Study. Patients with low-density lipoprotein cholesterol (LDL-C) ≥ 140 mg/dL and max-IMT ≥ 1.1 mm were randomized to rosuvastatin or pravastatin therapy for 12 months. Dosages were allowed to increase to 10 mg/day and 20 mg/day to achieve LDL-goals (aggressive goals for rosuvastatin group and guideline goals for pravastatin group). For the main analysis, we assessed 200 high-risk patients (105 in the rosuvastatin group), as category III or secondary prevention according to the Japan Atherosclerosis Society guideline 2007, whereas we assessed 289 patients in the other analysis. Rosuvastatin significantly slowed the percentage change in mean-IMT at 12 months compared with pravastatin (1.40 ± 10.03% versus 6.43 ± 13.77%, P = 0.005). LDL-C was reduced by 48.1% in the rosuvastatin group and 27.9% in the pravastatin group. The rate of achieving the LDL-C goal was significantly greater in the rosuvastatin group compared with the pravastatin group (P < 0.001). Rosuvastatin slowed the change in mean-IMT in the presence of every risk factor. Thus, intensive lipid-lowering therapy reduced progression of carotid IMT in high-risk patients.

ABSTRACT

A 64-year-old man underwent a descending aortic replacement for a chronic type B dissecting aneurysm with left thoracotomy. The patient was weaned from the mechanical ventilator immediately after surgery without any neurological complications. However, on the second post-operative day, he suddenly suffered from cardiopulmonary arrest when talking with his family. Despite 6 hours of cardiopulmonary resuscitation, the patient died. The postmortem examination revealed a 1000 mL blood volume and huge hematoma in the pericardium owing to a retrograde type A dissection, which descended from an intimal laceration between the common carotid and left subclavian arteries that corresponded with aortic cross clamping. We here report a rare case of iatrogenic retrograde type A dissection caused by surgical clamping on the aortic arch 2 days post-surgery.

ABSTRACT

A 59-year-old female underwent surgery for a primary malignant pericardial mesothelioma. She presented with progressive dyspnea, and several imaging studies demonstrated a 65 × 22 mm tumor in the aortopulmonary window, accompanied by massive pericardial effusion. The tumor was successfully excised with clean surgical margins under cardiopulmonary bypass, followed by patch reconstruction of the pulmonary artery, and was diagnosed as an epithelioid type of malignant pericardial mesothelioma. The patient tolerated the operation and subsequent adjuvant chemotherapy without any complications. She remained alive and asymptomatic for almost 3 years after surgery, despite the fact that the median survival of this disease is 6-10 months. This patient is the second longest postoperative survivor of this extremely rare, aggressive neoplasm.

ABSTRACT

OBJECTIVE: The management strategy for type A acute aortic dissection (AAD) with intramural hematoma (IMH) remains controversial. The aim of this study was to compare the outcomes of emergency surgery and medical treatment for patients with acute type A IMH. METHODS: One hundred seventy-one patients with acute type A IMH, whose average age was 69.4 years (range, 39-90 years) were divided into 3 groups: groups I and II consisted of 74 and 33 patients undergoing emergency surgery for complicated and uncomplicated type A IMH, respectively, and group III comprised 66 patients who were treated conservatively. We compared the 3 groups in terms of mortality and morbidity. RESULTS: In group I, postoperative hospital mortality was 5.4% (4 patients). In group II, all patients survived without any complications after surgery. On the other hand, in group III, 5 patients underwent emergency surgery within 7 days after onset owing to newly developed cardiac tamponade and 17 (25.8%) patients died in the hospital, which was a significantly higher rate than those in groups I and II. Furthermore, although the group III patients survived, 5 patients required mechanical ventilation owing to heart failure or pneumonia, and 4 patients had a stroke during the hospital stay. There was no difference in actuarial survivals at 10 years, which were 64.2% in group I, 64.9% in group II, and 68.7% in group III. CONCLUSIONS: Emergency surgery for patients with type A IMH showed favorable mortality rates because most of the patients were in hemodynamically stable condition preoperatively. On the other hand, several patients died suddenly during medical care. Emergency surgical treatment may provide a better outcome than medical treatment at the time of onset, even for patients with type A IMH.

ABSTRACT

PURPOSE: We assessed the incidence of coronary artery disease (CAD) during hospitalization after emergency surgery for a type A acute aortic dissection. METHODS: A total of 123 patients underwent multi-slice computed tomography (MSCT) scans during an early stage after surgery. The patients were divided into two groups: group I consisted of 14 patients (11.4%) who had coronary artery stenosis of more than 75% on MSCT, and group II consisted of 109 patients (88.6%) who had no coronary lesions. RESULTS: The prevalence of diabetes, dyslipidemia and a smoking history was significantly higher in group I. Although the serum low-density lipoprotein cholesterol levels were similar, the high-density lipoprotein cholesterol (HDL) level was significantly lower in group I (36.4 ± 7.9 mg/dl) than in group II (49.6 ± 13.5 mg/dl, P = 0.0005). The maximum carotid intima-media thickness (IMT) was significantly thicker in group I (1.17 ± 0.37 mm) compared to group II (0.96 ± 0.33 mm, P = 0.0297). The logistic regression analysis detected that a carotid IMT over 1.1 mm (odds ratio 4.35, P = 0.0371) and HDL less than 40 mg/dl (odds ratio 3.90, P = 0.0482) were predictors for CAD. CONCLUSIONS: CAD screening should be recommended for patients with aortic dissection who have several atherosclerosis risk factors, even after emergency surgery.

ABSTRACT

BACKGROUND: Febuxostat has been reported to have a stronger effect on hyperuricemia than allopurinol. METHODS AND RESULTS: Cardiac surgery patients with hyperuricemia (n=141) were randomized to a febuxostat group or an allopurinol group. The study was single-blind, so the treatment was not known by the investigators. The primary endpoint was serum uric acid (UA) level. Secondary endpoints included serum creatinine, urinary albumin, cystatin-C, oxidized low-density lipoprotein (LDL), eicosapentaenoic acid/arachidonic acid ratio, total cholesterol, triglycerides, LDL, high-density lipoprotein, high-sensitivity C-reactive protein, blood pressure, heart rate, pulse wave velocity (PWV), ejection fraction, left ventricular mass index (LVMI), and adverse reactions. UA level was significantly lower in the febuxostat group than the allopurinol group from 1 month of treatment onward. Serum creatinine, urinary albumin, cystatin-C and oxidized LDL were also significantly lower in the febuxostat group. There were no significant changes in systolic blood pressure, PWV, and LVMI in the allopurinol group, but these parameters all had a significant decrease in the febuxostat group. CONCLUSIONS: Febuxostat was effective for high-risk cardiac surgery patients with hyperuricemia because it reduced UA more markedly than allopurinol. Febuxostat also had a renoprotective effect, inhibited oxidative stress, showed anti-atherogenic activity, reduced blood pressure, and decreased PWV and LVMI.

ABSTRACT

BACKGROUND: Recently, it was reported from the Justification for Atherosclerosis Regression Treatment (JART) Study that intensive therapy with rosuvastatin significantly slowed progression of carotid intima-media thickness (IMT) compared with conventional therapy with pravastatin at 12 months. To assess the long-term efficacy of intensive therapy, the present extension study was conducted. METHODS AND RESULTS: Subjects in the intensive therapy group of the JART Study were asked to participate in the extension study and to continue rosuvastatin treatment. A total of 113 subjects were enrolled into the extension study and were included in the analysis. At 24 months, the mean daily dose of rosuvastatin (±SD) was 7.9±2.9 mg. Mean change in mean IMT was -0.005 mm (range, -0.024 to 0.015 mm) at 24 months (P=0.633, compared with baseline). Rosuvastatin lowered low-density lipoprotein cholesterol (mean±SD) by 46.4±13.8% and elevated high-density lipoprotein cholesterol (mean±SD) by 8.9±24.0% at 24 months compared with baseline. Gray scale median was measured in 25 subjects. It increased by 16.93±33.12 (mean±SD) % at 12 months and by 22.50±52.83% at 24 months from baseline (P=0.017, P=0.044, respectively). CONCLUSIONS: Two-year treatment with rosuvastatin inhibited progression of carotid IMT. Rosuvastatin also improved the plaque composition, and this qualitative change occurred relatively early after starting therapy.
