Case report: Successful treatment of malignant pericardial effusion with pericardiocentesis, concurrent anti-inflammatory therapy and cancer therapy.

Despite significant advancements in systemic anticancer therapies, cardiac tamponade remains a serious and potentially life-threatening complication in metastatic breast cancer (MBC). However, there is a paucity of comprehensive research investigating alternative management approaches, such as pericardiocentesis and anti-inflammatory therapy (AIT), to effectively address cardiac tamponade and mitigate the risk of heart failure arising from constrictive physiology (CP) in patients with MBC when traditional systemic anticancer drugs fail to yield favorable outcomes. Herein, we describe two cases of MBC with cardiac tamponade that occurred despite the administration of effective systemic anticancer drugs. In each case, pericardial effusion was detected in a patient who was undergoing palliative anticancer therapy for human epidermal growth factor receptor 2 (HER2)-positive MBC. The patients in these cases were successfully treated with pericardiocentesis and AIT (prednisolone and colchicine) for subsequent CP without substitution with their systemic anticancer drugs. Cardiac tamponade and CP are regarded as signs of advanced cancer and are associated with a worse clinical outcome in general; however, they can still be treated with an effective anticancer drug, pericardiocentesis, and management of CP by cardiooncology specialists.

Prediction of cardiac events following concurrent chemoradiation therapy for non-small-cell lung cancer using FDG PET.

OBJECTIVE: No imaging biomarkers are available for the prediction of cardiac events following concurrent chemoradiation therapy (CCRT) for non-small-cell lung cancer (NSCLC). We evaluated whether F-18 fluorodeoxyglucose positron emission tomography (FDG PET) early after CCRT, in addition to cardiac dosimetry, could predict late cardiac events in NSCLC. METHODS: We retrospectively enrolled 133 consecutive patients with locally advanced, unresectable stage III NSCLC, who underwent FDG PET early after CCRT and survived at least 6 months. The primary endpoint was cardiac event ≥ grade 2 according to the Common Terminology Criteria for Adverse Events (version 5.0). Myocardial FDG uptake was measured and its association with the risk of cardiac events was evaluated. RESULTS: FDG PET was performed after a median interval of 11 days of completing CCRT. Overall, 42 (32%) patients experienced cardiac events during a median follow-up of 45 months. The mean heart dose, maximum left ventricular (LV) standardized uptake value (SUV), changes in maximum and mean LV SUV, right ventricular uptake, tumor stage, white blood cell count, and diabetes were associated with cardiac events in univariable analysis. In multivariable analysis, maximum LV SUV (cutoff > 12.84; hazard ratio [95% confidence interval] = 2.140 [1.140-4.016]; p = 0.018) was an independent predictor of cardiac events along with the mean heart dose (> 11.1 Gy; 3.646 [1.792-7.417]; p < 0.001) and tumor stage (IIIB; 1.986 [1.056-3.734]; p = 0.033). It remained predictive of cardiac events in those with higher mean heart dose but not in those with lower mean heart dose. CONCLUSIONS: Early FDG PET after CCRT for NSCLC could aid in predicting late cardiac events, especially in patients with higher mean heart dose.

Characteristics and Clinical Outcomes of Cancer Patients who Developed Constrictive Physiology After Pericardiocentesis.

BACKGROUND AND OBJECTIVES: This study aimed to identify the characteristics and clinical outcomes of cancer patients who developed constrictive physiology (CP) after percutaneous pericardiocentesis. METHODS: One-hundred thirty-three cancer patients who underwent pericardiocentesis were divided into 2 groups according to follow-up echocardiography (CP vs. non-CP). The clinical history, imaging findings, and laboratory results, and overall survival were compared. RESULTS: CP developed in 49 (36.8%) patients after pericardiocentesis. The CP group had a more frequent history of radiation therapy. Pericardial enhancement and malignant masses abutting the pericardium were more frequently observed in the CP group. Fever and ST segment elevation were more frequent in the CP group, with higher C-reactive protein levels (6.6±4.3mg/dL vs. 3.3±2.5mg/dL, p<0.001). Pericardial fluid leukocytes counts were significantly higher, and positive cytology was more frequent in the CP group. In baseline echocardiography before pericardiocentesis, medial e' velocity was significantly higher in the CP group (8.6±2.1cm/s vs. 6.5±2.3cm/s, p<0.001), and respirophasic ventricular septal shift, prominent expiratory hepatic venous flow reversal, pericardial adhesion, and loculated pericardial fluid were also more frequent. The risk of all-cause death was significantly high in the CP group (hazard ratio, 1.53; 95% confidence interval,1.10-2.13; p=0.005). CONCLUSIONS: CP frequently develops after pericardiocentesis, and it is associated with poor survival in cancer patients. Several clinical signs, imaging, and laboratory findings suggestive of pericardial inflammation and/or direct malignant pericardial invasion are frequently observed and could be used as predictors of CP development.

Clinical impact of echocardiography-defined pulmonary hypertension on the clinical outcome in patients with multiple myeloma.

Pulmonary hypertension (PH) is a complication of multiple myeloma (MM); however, the clinical outcomes and prognosis are relatively not well known. We aimed to investigate the risk factors of transthoracic echocardiography-defined PH and its impact on the clinical outcome in patients with MM.A retrospective study was performed using data from the Chonnam National University Hwasun Hospital database for patients who underwent transthoracic echocardiography (TTE) within 1 month of the MM diagnosis between January 2007 and December 2017. PH was defined as an estimated right ventricular systolic pressure (RVSP) > 40 mmHg. A total of 390 patients were included. TTE-defined PH was observed in 107 patients (27%). During the follow-up period (median, 688 days), all-cause death was noted for 134 patients (34.4%). In the Kaplan-Meier survival analysis, the cumulative overall survival and cardiovascular death-free survival rates were significantly lower in the PH group than in the non-PH group (P < .001). In the propensity score-matched population, RVSP > 40 mmHg on TTE and history of congestive heart failure (CHF) were identified as the significant independent predictors of all-cause and cardiovascular death.This study reports that the prevalence of TTE-defined PH is higher in patients with MM than in the general population. Moreover, TTE-defined PH and a history of CHF are the independent prognostic factors for all-cause and cardiovascular death in patients with MM. These results highlight the risk of associated cardiovascular disease in patients with MM and emphasize the importance of management strategies that prevent the deterioration of cardiac function.

Left atrial longitudinal strain as a predictor of Cancer therapeutics-related cardiac dysfunction in patients with breast Cancer.

BACKGROUND: We investigated the usefulness of the left atrial (LA) strain measurement on the prediction of upcoming cancer therapeutics-related cardiac dysfunction (CTRCD) after trastuzumab therapy in patients with breast cancer who did not develop CTRCD after chemotherapy. METHODS: A total of 72 females with breast cancer who did not develop CTRCD after chemotherapy and underwent additional trastuzumab therapy were divided into CTRCD (n = 13) and no CTRCD group (n = 59). Echocardiographic measurements including left ventricular global longitudinal strain (LVGLS) and peak atrial longitudinal strain (PALS) decline were compared. RESULTS: CTRCD was identified in 13 patients (18.1%) after additional trastuzumab therapy. Baseline echocardiographic findings were not different. After the completion of chemotherapy, conventional echocardiographic parameters were not different, but PALS decline (15.0 ± 4.7 vs. 8.9 ± 3.2%, p < 0.001) and LVGLS decline (10.5 ± 1.3 vs. 9.1 ± 1.1%, p = 0.002) were significantly greater in CTRCD than in no CTRCD group. PALS decline at the time of chemotherapy completion could predict future CTRCD after trastuzumab therapy with better sensitivity and specificity (cutoff value 11.79%, sensitivity 76.9% and specificity 81.4%) than LVGLS decline (cutoff value 9.9%, sensitivity 69.2% and specificity 78.0%). CONCLUSIONS: PALS or LVGLS decline developed before developing overt CTRCD after chemotherapy for breast cancer, and PALS decline showed better sensitivity and specificity in predicting future CTRCD than LVGLS decline. Serial measurement of PALS can be used as a useful parameter in the prediction of future CTRCD.

Impacts of non-recovery of trastuzumab-induced cardiomyopathy on clinical outcomes in patients with breast cancer.

OBJECTIVES: The impacts of non-recovery of trastuzumab-induced left ventricular dysfunction (LVD) on clinical outcomes in breast cancer have been poorly studied. We investigated the predictors of LV-functional non-recovery and its impacts on clinical outcomes in breast cancer patients with trastuzumab-induced LVD. METHODS AND RESULTS: A total of 243 patients with trastuzumab-induced LVD were divided into the recovered LVD group (n = 195) and non-recovered LVD group (n = 48). Major adverse clinical events (MACEs) including death, symptomatic heart failure (HF), and HF hospitalization (HHF) were compared. Hemoglobin and albumin levels were significantly lower in non-recovered LVD than in recovered LVD group. Non-recovered LVD group showed significantly larger LV end-diastolic and systolic dimension, higher pulmonary artery systolic pressure, lower LV ejection fraction (EF), and decreased global longitudinal strain than in recovered LVD group. Decreased LVEF, enlarged LV size, pulmonary hypertension, and anemia were independent predictors of LV-functional non-recovery. During 45.9 ± 23.5 months of follow-up, MACEs were developed in 32 patients: 15 deaths, 28 symptomatic HF, and 22 HHF. In Kaplan-Meier survival analysis, MACE free survival was significantly lower in non-recovered LVD group than in recovered LVD group (log rank p = 0.002). CONCLUSION: LV-functional non-recovery was not uncommon in breast cancer patients with trastuzumab-induced cardiomyopathy, and non-recovered LVD was significantly associated with MACEs. Decreased LVEF, enlarged LV size, pulmonary hypertension, and anemia were independent predictors of LV-functional non-recovery. Careful monitoring for MACEs and intensive medical management should be considered in trastuzumab-induced cardiomyopathy with these characteristics.

University athletes and changes in cardiac geometry: insight from the 2015 Gwangju Summer Universiade.

AIMS: There is a paucity of data regarding the changes of cardiac geometry in highly trained international and multiracial university athletes. We aimed to investigate the incidence of structural cardiac abnormalities and changes of cardiac geometry in highly trained university athletes. METHODS AND RESULTS: Comprehensive echocardiographic studies were performed in 1185 university athletes through the Check-up Your Heart Program during the 2015 Gwangju Summer Universiade. Participants were divided into two groups: normal vs. abnormal left ventricular (LV) geometry (concentric remodelling, concentric hypertrophy, or eccentric hypertrophy). Structural heart diseases associated with sudden cardiac death were not identified, but minor structural cardiac abnormalities were common in university athletes. One hundred and fifty-six athletes (13.2%) had abnormal LV geometry; concentric remodelling (n = 73, 6.2%), concentric hypertrophy (n = 25, 2.1%), and eccentric hypertrophy (n = 58, 4.9%). Abnormal LV geometry was significantly more common in athletes of African descent and in endurance, mixed, or power disciplines. In multivariate logistic regression analysis, athletes of African descent [odds ratio (OR) 2.16, 95% confidence interval (CI) 1.34-3.46; P = 0.001], endurance disciplines (OR 1.79, 95% CI 1.26-2.54; P = 0.001), and training time (OR 1.01, 95% CI 1.00-1.02; P = 0.045) were independent predictors of abnormal LV geometry. CONCLUSION: A large scale cardiovascular screening programme of the 2015 Summer Universiade demonstrated that abnormal LV geometry is not uncommon (13.2%) and concentric remodelling is the most common pattern of LV geometric change in young trained university athletes. Race, type of sport, and training time are significant predictors of abnormal LV geometry. Structural cardiac abnormalities are common in university athletes even though they are minor abnormalities.

Cardiac tamponade after radiofrequency ablation for hepatocellular carcinoma: Case report and literature review.

RATIONALE: Radiofrequency ablation (RFA) is a safe and effective local treatment modality with a low complication rate and is commonly used to treat hepatocellular carcinoma (HCC). The clinical outcome of RFA may be closely related to the location, size, and shape of index tumors, and major complications, including hemorrhage, liver abscess, infarction, visceral organ perforation, hemothorax, pneumothorax, tumoral seeding, and hepatic failure. Cardiac tamponade is a rare and serious life-threatening complication associated with RFA. To date, a review of the medical literature reported 5 cases of cardiac tamponade after RFA for HCC. Herein, we report another case of cardiac tamponade after RFA for HCC in a 56-year-old man. PATIENT CONCERNS: He had suffered from liver cirrhosis due to alcohol abuse. He had chronic obstructive pulmonary disease. Magnetic resonance imaging showed a 3.0-cm exophytic subcapsular HCC in segment IVa of left hepatic lobe. As the patient was at high risk for surgery because of poor lung function, RFA was selected as the treatment of choice. The index tumor was located in the vicinity of the diaphragm and colon. During RFA procedure, thermal injury to the adjacent diaphragm and colon was minimized by introducing artificial ascites. Bleeding or tumoral seeding was prevented by ablating the electrode track during electrode retraction. DIAGNOSIS: Two hours after RFA, the patient presented with dyspnea, chest discomfort, and low blood pressure (80/60 mm Hg), suggesting cardiac tamponade. Immediate follow-up contrast-enhanced computed tomography image depicted the slightly high attenuated hemopericardium. Transthoracic echocardiography (TTE) showed a moderate amount of pericardial effusion with tamponade and a large hematoma. INTERVENTIONS: Under fluoroscopy and portable echocardiography guidance, a cardiologist immediately inserted a 7-French pigtail catheter into the pericardial space and collected more than 200 cc of bloody pericardial fluid. OUTCOMES: After pericardiocentesis, the patient's symptoms and hemodynamic status were dramatically improved. Follow-up TTE showed scanty amount of pericardial effusion and the drainage catheter was removed. The patient was discharged. LESSONS: When treating HCC in the left lobe (especially segments II and IVa), attention should be paid to cardiac tamponade. The early diagnosis and immediate treatment of cardiac tamponade may increase the chance of cure.

Complete atrioventricular block as an initial manifestation of recurred oral cavity cancer: a case report.

BACKGROUND: Intracardiac invasion of head and neck cancer is extremely rare. Here, we report a case of recurred oral cavity cancer presenting with complete atrioventricular (AV) block caused by cardiac metastasis. CASE PRESENTATION: A 70-year-old male presented with dizziness for 2 days. He had a history of oral cavity cancer a year ago, and the tumor was treated by surgical excision after induction chemotherapy and concurrent chemoradiation therapy. Electrocardiography showed complete AV block with ventricular escape rate of 43 beats per minute. Cardiac imaging revealed about 4.0 × 2.0 cm-sized mass invading interventricular septum and AV nodes and protruding into the right ventricle. Magenetic resonance imaging of head and neck demonstrated recurred mass in oral cavity and maxillary sinus. Fluorodeoxyglucose-positron emission tomography showed hypermetabolic lesion in both oral cavity and the heart around interventricular septum and atrioventricular node indicating recurred oral cavity cancer with cardiac metastasis. Permament pacemaker of DDD type was implanted for the symptomatic complete AV block, and palliative chemotherapy was initiated. CONCLUSION: The present case demonstrated that oral cavity cancer can metastasize to the heart, and complete AV block may be an initial manifestation of the recurrence of extracardiac cancer with intracardiac invasion.

Masked inherited primary arrhythmia syndromes in sudden cardiac death patients accompanied by coronary vasospasm.

BACKGROUND/AIMS: Coronary vasospasms are one of the important causes of sudden cardiac death (SCD). Provocation of coronary vasospasms can be useful, though some results may lead to false positives, with patients potentially experiencing recurrent SCD despite appropriate medical treatments. We hypothesized that it is not coronary vasospasms but inherited primary arrhythmia syndromes (IPAS) that underlie the development of SCD. METHODS: We analyzed 74 consecutive patients (3.8%) who survived out-of-hospital cardiac arrest among 1,986 patients who had angiographically proven coronary vasospasms. Electrical abnormalities were evaluated in serial follow-up electrocardiograms (ECGs) during and after the index event for a 3.9 years median follow-up. Major clinical events were defined as the composite of death and recurrent SCD events. RESULTS: Forty five patients (60.8%) displayed electrocardiographic abnormalities suggesting IPAS: Brugada type patterns in six (8.2%), arrhythmogenic right ventricular dysplasia patterns in three (4.1%), long QT syndrome pattern in one (2.2%), and early repolarization in 38 (51.4%). Patients having major clinical events showed more frequent Brugada type patterns, early repolarization, and more diffuse multivessel coronary vasospasms. Brugada type pattern ECGs (adjusted hazard ratio [HR], 4.22; 95% confidence interval [CI], 1.16 to 15.99; p = 0.034), and early repolarization (HR, 2.97; 95% CI, 1.09 to 8.10; p = 0.034) were ultimately associated with an increased risk of mortality. CONCLUSIONS: Even though a number of aborted SCD survivors have coronary vasospasms, some also have IPAS, which has the potential to cause SCD. Therefore, meticulous evaluations and follow-ups for IPAS are required in those patients.

Clinical Characteristics and Outcomes of Acute ST-Segment Elevation Myocardial Infarction in Younger Korean Adults.

BACKGROUND AND OBJECTIVES: This study aims to investigate the clinical features, angiographic findings, and outcomes of younger Korean ST-segment elevation myocardial infarction (STEMI) patients. SUBJECTS AND METHODS: We analyzed major adverse cardiac events (MACE) in the Korea Acute Myocardial Infarction Registry from November 2005 to October 2010. The registered patients were divided into two groups; young age group (<65 years) and old age group (≥65 years). RESULTS: The young age group included 5281 patients (age, 53±7.8 years), and the old age group included 4896 patients (age, 74.3±6.5 years). Male gender, smoking, family history, dyslipidemia, and metabolic syndrome were more frequently observed in the young age group than in the old age group (89.5% vs. 59.3%, p<0.001; 77.3% vs. 47.2%, p<0.001; 11% vs. 4.6%, p<0.001; 11.2% vs. 7.7%, p<0.001; 67.6% vs. 62.9%, p<0.001). Most of the young Korean adults with STEMI complained of typical chest pain (89.8%), and they had a shorter symptom-to-door time (12±53.2 hours vs. 17.3±132 hours, p=0.010). The young age group showed a favorable prognosis, which was represented by the MACE, compared with the old age group at one month (1.8% vs. 2.8%, p=0.028), six months (6.8% vs. 8.2%, p<0.001), and twelve months (10.1% vs. 11.9%, p=0.025). However, there was no significant difference in the adjusted MACE rate at one month {hazard ratio (HR) 0.95, 95% confidence interval (CI) 0.60-1.51, p=0.828} and twelve months (HR 0.86, 95% CI 0.68-1.10, p=0.233). CONCLUSION: Younger Korean adults with STEMI have clinical outcomes similar to old aged patients, and therefore, they should be treated intensively like the elderly patients.

Totally occluded grafted right internal mammary artery to anomalously originated right coronary artery.

An anomalous aortic origin of a coronary artery is rare and surgical intervention is recommended when the patient is symptomatic. We performed coronary artery bypass graft surgery in a 21-year-old male patient with a right coronary artery anomalously originating from the left coronary sinus. The artery was significantly stenosed by external compression between the aorta and the pulmonary artery. However, the graft became occluded 1 year after the operation. In such cases, the dynamic nature of the stenosis can cause relatively intact antegrade competitive flow from the native coronary artery and lead to an occlusion of the grafted artery. Methods for evaluating flow rates or intraluminal pressures of native arteries could be helpful in decision-making in similar cases.
