Abstract Objective: Transthoracic echocardiography (TTE) is generally recognized as the top choice for detecting myocardial and cardiac cavity lesions. Sonographers mostly focus on myocardial, cardiac cavity and cardiac hemodynamics, whereas the abnormal extra-cardiac lesions are always unrecognized. The aim of this study was to investigate the ultrasonic image features in abnormal extra-cardiac lesions and the value of TTE in the detection of extra-cardiac lesions.Methods: 49 cases of abnormal extra-cardiac lesion detected by TTE from January 2014 to December 2019 were collected, which were confirmed by pathology. The two-dimensional ultrasonic characteristics and the relationships with the cardiac and great vessels were summarized on the basis of multi-view by TTE. All patients were also performed by computed tomography (CT). Results: In 49 patients with abnormal extra-cardiac lesions, 37 malignant cases and 12 benign cases were included. There were 41 cases (41/49,86.67%) of mediastinal lesions and 8 cases (8/49,16.33% ) of lung lesions. The maximum diameter ranged from 3.2cm to 13.66cm, and the median diameter was about 7.4cm, among which 29 cases (29/49,59.18%) were larger than 5cm. 4 cases (4/49, 4.08%) of cystic anechoic lesions were pericardial cyst. 2 cases (2/49, 4.08%) of cystic-solid echogenic lesions were teratoma. The remaining 45 cases (45/49, 91.84%) presented as solid hypoechoic or heterogeneous masses. 6 cases compressed the heart and 21 cases encroached on the heart and vessels. Diagnosis coincidence rates of TTE and CT were respectively 77.55% and 93.88%, with a statistical difference (p =0.012).Conclusion: Although the diagnostic coincidence rate of TTE is slightly lower than that of CT, TTE has certain diagnostic value for extra-cardiac lesions.

Abstract Purpose Patients with a functionally univentricular heart represent one of the most common severe cardiac lesions with a prevalence of 3 per 10,000 live births. Hemodynamics of the singular ventricle is a major research topic in cardiology and there exists a relationship between fluid dynamical features and cardiac behavior in health and disease. The aim of the present work was to compare intraventricular flow in single right ventricle (SRV) patients and subjects with healthy left hearts (LV) through patient-specific CFD simulations. Methods Three-dimensional real-time echocardiographic images were obtained for five SRV patients and two healthy subjects and CFD simulations with a moving mesh methodology were performed. Intraventricular vortex formation and vortex formation time (VFT) as well as the turbulent kinetic energy (TKE) and ventricular washout were evaluated. Results The results show significantly lower values for the VFT and the TKE in SRV patients compared with healthy LV subjects. Furthermore, vortex formation does not progress to the apex in SRV patients. These findings were confirmed by a significantly lower washout in SRV patients. Conclusions The study pinpoints the intriguing role of intraventricular flows to characterize performance of SRVs that goes beyond standard clinical metrics such as ejection fraction.

An anomalous left hepatic venous (LHV) connection is an extremely rare cardiac malformation, and left hepatic venous route abnormalities not associated with other cardiac lesions do not require surgical treatment because they are physiologically benign. However, when venous route abnormalities exist with associated cardiac lesions, the conduct of the cardiac surgical repair must accommodate the abnormal venous anatomy, especially in total cavopulmonary connection patients. Herein, we present a rare case of a 7-year-old Chinese boy about 1 year post bilateral superior vena cava pulmonary anastomosis who presented with severe cyanosis and was referred to our department. However, the patient showed an unexpected gradual decrease in blood oxygen saturation to 60–70% after the extracardiac total cavopulmonary connection (ETCPC) operation. Emergency echocardiography and computed tomography confirmed that the LHV entered the right atrium. Subsequently, the patient undergone completion of a staged TCPC with intra-atrial tunnel technique. This illustrative report highlights the essence of improving the preoperative accurate diagnosis to avoid unplanned reoperation in China, especially for the remote rural areas of eastern countries where the level of health care and services is relatively backward. Failure to identify anomalous LHV connection, in this case, will delay effective treatment past the optimal treatment time.

The role of SARS-CoV-2 as a direct cause in the cardiac lesions in patients with severe COVID-19 remains to be established. Our objective is to report the pathological findings in cardiac samples of 30 patients who died after a prolonged hospital stay due to Sars-Cov-2 infection. We performed macroscopic, histological and immunohistochemical analysis of the hearts of 30 patients; and detected Sars-Cov-2 RNA by RT-PCR in the cardiac tissue samples. The median age of our cohort was 69.5 years and 76.6% were male. The median time between symptoms onset and death was 36.5 days. The main comorbidities were arterial hypertension (13 patients, 43.3%), dyslipidemia (11 patients, 36.7%), cardiovascular conditions (8 patients, 26.7%), and obesity (8 patients, 26.7%). Cardiovascular conditions included ischemic cardiopathy in 4 patients (13.3%), hypertrophic cardiomyopathy in 2 patients (6.7%) and valve replacement and chronic heart failure in one patient each (3.3%). At autopsy, the most frequent histopathological findings were coronary artery atherosclerosis (8 patients, 26.7%), left ventricular hypertrophy (4 patients, 13.3%), chronic epicardial inflammation (3 patients, 10%) and adipose metaplasia (2 patients, 6.7%). Two patients showed focal myocarditis, one due to invasive aspergillosis. One additional patient showed senile amyloidosis. Sars-Cov-2 RNA was detected in the heart of only one out of 30 patients, who had the shortest disease evolution of the series (9 days). However, no relevant cardiac histological alterations were identified. In present series, cardiac pathology was only modest in most patients with severe COVID-19. At present, the contribution of a direct effect of SARS-CoV-2 on cardiac lesions remains to be established.

Cardiac lesions are responsible for approximately 60-70% of sudden deaths. Histopathological examination of heart on autopsy plays an essential role in determining the cause of death.The present study was conducted to analyse histopathological spectrum of various cardiac lesions in autopsy specimens.This retrospective randomized study was conducted in the Department of Pathology, Pt. B. D. Sharma, PGIMS, Rohtak, Haryana. A total of 1152 autopsies were analysed, irrespective of cause of death. Among them heart was included in 1062 autopsies, out of which 62 were autolysed. Hence, 1000 specimen of whole heart were included in our study. A detailed gross and microscopic examination was done and histopathological findings were correlated clinically.Atherosclerosis was the most common cardiac lesion seen in 610 out of 1000 autopsied heart (61%), followed by ischaemic heart disease in 346 cases (34.6%). 27 cases had pericarditis, 23 cases revealed myocardial hypertrophy, 16 cases showed myocarditis, 11 cases had ventricular haemorrhage, 8 cases revealed changes of electrocution, 7 cases had tuberculosis, 6 cases had calcification of valve and 4 cases had metastasis from carcinoma. One case each of infective endocarditis, rheumatic heart disease and aortitis were also noted. The cause of death was not identified in 304 cases. Left anterior descending artery was most frequently involved vessels (35.02%) followed by left circumflex artery (33.41%) then right coronary artery (31.57%). Out of three major vessels 16.24% had single vessel involvement whereas 32.14% & 51.62% cases had two vessels and three vessels involvement respectively. Ischemic heart disease with coronary artery atherosclerosis was found to be the leading cause of death with triple vessel disease as the most common pattern of involvement.

With the number of patients living with congenital heart disease steadily increasing, relevant training in anesthesia care for these patients is becoming ever more important. Written by experts in the field, this highly illustrated book succinctly reviews the pathophysiology of congenital cardiac lesions along with important anesthetic implications for each. Case scenarios cover patients of wide-ranging ages, with a focus on care in non-cardiac operating room settings, including the general operating room, cardiac catheterization laboratory and radiology. Divided into sections corresponding to the anatomic classification of each cardiac lesion, the book includes keywords for easy cross-referencing. Several lesions have multiple scenarios presented in order to allow readers to learn how to discern more critically ill patients. The stepwise approach to understanding complex lesions provides a readily accessible guide for all anesthesia providers who care for patients with congenital heart disease. The book is also a useful tool for intraoperative teaching.

Background To evaluate the efficacy and safety of ascending aortoiliac bypass surgery for one-stage repair of adult coarctation of the aorta (CoA) and concomitant cardiac disease. Methods From March 2012 to October 2018, 51 consecutive CoA patients were treated with ascending aorta to bilateral iliac artery bypass concomitant with and cardiac surgerical procedures performed for a variety of reasons. A Y-shaped graft was used for the bypass procedure. We evaluated early outcomes, including postoperative death, systolic blood pressure and differences between upper and lower limb blood pressure. Results The average age was 41 years and 64.7% of patients were men. Simultaneous cardiac procedures included aortic valve replacement, ventricular septal defect repair, Bentall procedures and Wheat procedures. No deaths occurred in the early postoperative period. Three patients had delayed healing at the site of the abdominal lower quadrant incisions. The average systolic pressure in the upper limb and the average difference between the upper- and lower-limb blood pressure decreased significantly after surgery (162.7 ± 13.4 mmHg vs 128.4 ± 6.7 mmHg, P = .000; 69.6 ± 15.6 mmHg vs 8.7 ± 7.6 mmHg, P = .000, respectively); The systolic blood pressure in the lower limb increased after bypass surgery (93.1 ± 6.2 mmHg vs 119.6 ± 7.7 mmHg, P = .000). The follow-up rate was 100%, with an average follow-up time of 61 months. Six patients (11.8%) had graft stenosis or occlusion. Three patients (5.9%) underwent endovascular embolectomy. Conclusions In our small series, ascending aortoiliac bypass for one-stage repair of CoA with concomitant cardiac lesions appears safe and efficacious in effectively reduceing differences between upper and lower limb systolic blood pressure. Further study with larger sample size and longer follow-up is needed.

Abstract Background: Although rare, coronary artery anomalies can have significant clinical implications. Total anomalous origin of the coronary arteries from the pulmonary artery (TCAPA) represents a rare subtype of coronary artery anomaly for which little is known. The aim of this review was to characterise the presentation, utilised diagnostic modalities, associated cardiac lesions, and treatment strategies in patients with TCAPA. Methods: A systematic review was performed for cases of TCAPA using PubMed, Embase, and Web of Science. Keywords searched included “total anomalous origin of the coronary arteries from the pulmonary artery,” “single ostium anomalous coronary artery from the pulmonary artery,” and “anomalous origin of both coronary arteries from the pulmonary artery.” Results: Fifty-seven cases of TCAPA were identified in 50 manuscripts. Fifty-eight per cent of patients were male and the median age at presentation was 10 days (mean 1.71 ± 6.6 years, range 0 days–39 years). Most patients were symptomatic at the time of presentation; cyanosis (n = 22) and respiratory distress (n = 14) were the most common symptoms. Cases were most commonly diagnosed at autopsy (n = 26, 45.6%), but operative intervention was pursued in 22 cases (45.6%); aortic re-implantation (n = 14) and a Takeuchi-type repair (n = 7) were the most common routes of repair. Conclusions: The clinical presentation of patients with TCAPA was found to be variable, likely related to the presence of associated cardiac lesions. TCAPA should be considered in patients with suspected anomalous origin of the left coronary artery from the pulmonary artery for the serious consequences that can occur if not promptly corrected.
