Introduction: Sinus of Valsalva aneurysm (SOVA), a rare cardiac malformation, is usually congenital and rarely acquired and most commonly occurring in the right coronary sinus. The clinical presentation of patients with SOVA varies. It is usually asymptomatic when it has not ruptured, and when it compresses neighboring structures or ruptures, it can lead to heart failure or shock, at which point urgent surgical intervention is usually required. Rupture of the sinus of Valsalva aneurysm (RSOVA) during pregnancy is really hard to come by, especially if the clinical presentations resemble that of an acute myocardial infarction. This report describes a pregnant woman with severe chest pain and hypotension with aVR and V1 ST-segment elevation due to RSOVA., Patient Concerns: Effects of RSOVA on the fetus, disease survival, and prognosis., Diagnosis: RSOVA., Interventions: Open SOVA repair., Outcomes: The patient's blood pressure returned to normal range and clinical symptoms disappeared after the surgery. After 3 months of follow-up, the patient was hemodynamically stable without chest discomfort, and an echocardiogram showed a normal aortic sinus., Conclusion: Progressive aneurysm dilatation or rupture has a poor prognosis. A thorough history and physical examination are fundamental, with echocardiography being the initial diagnostic tool of choice, and other ancillary tests (e.g., computed tomography) being used to complement and confirm the diagnosis. Surgery remains the current treatment of choice for patients with RSOVA, while the continuation of pregnancy in pregnant patients with RSOVA remains a case-by-case measure., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Purpose To investigate the association between the anomalous aortic origin of the right coronary artery (R-AAOCA) from the left coronary sinus with interarterial course (IAC) found at coronary CT angiography and sudden cardiac death using a large data set from five university hospitals. Materials and Methods From a total of 89 314 CCTA scans (January 2009 to December 2016) that were retrospectively collected, 316 patients with R-AAOCA from the left sinus with IAC were retrospectively collected. After excluding patients with less than 2 years of follow-up, patients who had already undergone cardiovascular surgery or intervention, and patients with arrhythmia or heart failure before undergoing coronary CT angiography, 224 patients were analyzed. Follow-up was terminated upon the occurrence of major adverse cardiovascular events (MACE). Logistic regression was used to identify clinical and radiologic information as independent predictors of MACE. Results The period prevalence of R-AAOCA from the left sinus with IAC was 0.354%. The mean age was 62.03 years, with a male-to-female ratio of 182:134. During follow-up, 19 of 224 patients (8.5%) experienced MACE, but none had sudden cardiac death. Of these cases, only seven (3.13%) were suspected of being due to R-AAOCA from the left sinus with IAC and all of them had unstable angina. Coronary artery disease was significantly associated with MACE ( P < .001), while no significant correlation was observed with radiologic features. Conclusion Sudden cardiac death was not associated with R-AAOCA from the left sinus with IAC found at coronary CT angiography. The occurrence of MACE was low, with coronary artery disease being the sole significant predictor of a patient's prognosis.

Guidewire loss is a rare complication of central venous catheterization. A 65-year-old male was hospitalized in a high-dependency unit for exacerbation of chronic obstructive pulmonary disease, pneumonia, erythrocytosis, and clinical signs of heart failure. Upon admission, after an unsuccessful right jugular approach, a left jugular central venous catheter was placed. The next day, chest radiography revealed the catheter located in the left parasternal region, with suspected retention of the guidewire, visually confirmed by the presence of its proximal end inside the catheter. The left parasternal location of the catheter and the typical projection of the guidewire in the coronary sinus, later confirmed by echocardiography, raised suspicion of a persistent left superior vena cava (PLSVC). Agitated saline injected into the left antecubital vein confirmed bubble entry from the coronary sinus into the right atrium. After clamping the guidewire, the catheter was carefully retrieved along with the guidewire without any complications. This is the first reported case of guidewire retention in PLSVC and coronary sinus. It underscores the potential causes of guidewire loss and advocates preventive measures to avoid this potentially fatal complication., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2024 Palić et al.)

Unroofed coronary sinus syndrome is a rare congenital cardiac anomaly, involving some anatomical variations. Approximately 60% of patients with unroofed coronary sinus syndrome have a concomitant atrial septal defect, which is termed unroofed coronary sinus atrial septal defect (CSASD). The precise detection of these abnormalities has been usually difficult with conventional echocardiography, mostly due to its small and complex structures. Herein, we report a case with unroofed coronary sinus atrial septal defect, in which preoperative contrast-enhanced computed tomography (CT) was useful in the operative decision making. We successfully repaired the defective roof of the coronary sinus with a bovine patch, while eliminating the inter-atrial shunt. The patient's postoperative course was uneventful with no residual shunt.

Background: Right coronary artery (RCA) fistulized to the coronary sinus is rare condition in adult cardiac anomalies, and the management and operative indication are controversial., Case Presentation: We describe the case of a 45-year female patient who presented with exertional dyspnea, accompanied by intermitted lower limbs and facial edema. She was diagnosed with severe tricuspid regurgitation second to a severely dilated RCA fistulized to the coronary sinus. After multidisciplinary discussion, she underwent surgery through routine medium sternotomy, the right atrium was opened under cardiopulmonary bypass. The coronary arteriovenous fistula from the distal portion of RC to a severely enlarged coronary sinus was found. Trans-coronary sinus closure of the fistula was performed with continuous stitching and a tricuspid ring annuloplasty was done. The patient recovered uneventful post operation., Conclusion: According to current literatures, surgical treatment was adopted for this case, instead of endovascular intervention. The optimal approach for these cases should consider the heart's anatomical characteristics. But we need to be aware of the occurrence of myocardial infarction and tricuspid regurgitation in the early and late stage after operation., (© 2022. The Author(s).)

Coronary artery fistula draining into the coronary sinus is a rare vascular malformation, and its diagnosis and clinical manifestations usually occur late. We describe the case of a 72-year-old female patient with dyspnea on exertion (New York Heart Association Class III) associated with palpitations. The transthoracic echocardiogram showed significant tricuspid insufficiency. Cardiac catheterization showed aneurysm of the circumflex coronary artery and fistula of this artery draining into the coronary sinus. The patient underwent fistula ligation and tricuspid valve repair, with excellent surgical results.

Background: Anomalous aortic origin of the left coronary artery (AAOCLA) with an extended transseptal course behind the right ventricular outflow tract (RVOT) is a rare variant that poses challenges not addressed by current surgical techniques. We utilized a novel transconal approach in 7 consecutive patients., Methods: A retrospective review was made of a prospectively collected database for consecutive patients undergoing transconal unroofing of transseptal AAOLCA. Surgical repair entails transection of the RVOT, unroofing the septal course of the AAOLCA, followed by RVOT extension with a rectangular strip of autologous pericardium. Preoperative characteristics, operative details, and postoperative course were abstracted., Results: All 7 patients identified were symptomatic. Median age was 48 years (range, 12 to 62). The AAOLCA with transseptal course was confirmed by computed tomography angiography. Three patients had provocative testing demonstrating anterolateral ischemia. Four patients underwent cardiac catheterization with intravascular ultrasound and indexed fractional flow reserve, confirming flow-limiting lesion. Importantly, 3 patients had negative provocative noninvasive testing for ischemia. Median postoperative hospital length of stay was 6 days (range, 4 to 12). No mortality or major complications occurred during a median follow-up of 0.75 years. Postoperative evaluation demonstrated anatomically patent unroofed AAOLCA with improved indexed fractional flow reserve compared with preoperative (0.59 ± 0.16 vs 0.90 ± 0.03, P = .05)., Conclusions: Complete unroofing of AAOLCA with transseptal course repaired with posterior extension of RVOT is an effective technique with excellent early outcome. Multimodality provocative testing is critical to evaluate these lesions as individual studies may be misleading. Intravascular ultrasound with indexed fractional flow reserve is clinically useful to confirm the hemodynamic significance of specific lesions., (Copyright © 2021 The Society of Thoracic Surgeons.

Background: An isolated coronary sinus (CS) atrial septal defect (ASD) is defined as a CS unroofed in the terminal portion without a persistent left superior vena cava or other anomalies. This defect is rare and part of the wide spectrum of unroofed CS syndrome (URCS). Recently, several reports have described this finding. The database of New Tokyo Hospital was searched to determine the incidence of this defect. Additionally, to raise awareness of this condition, the findings from five patients with CS ASD who underwent surgical repair at New Tokyo Hospital are discussed., Case Presentation: The patients were three women and two men with an age range of 63-77 years. All patients underwent transthoracic echocardiography and computed tomography, and one underwent magnetic resonance imaging. In two patients, the defect was found unexpectedly intraoperatively; left-to-right shunting was apparent in the other three patients preoperatively. The pulmonary-to-systemic blood flow ratio ranged from 1.42 to 3.1 following cardiac catheterization, and oxygen saturation step-up was seen on the right side of the heart. Valvular regurgitation was seen in 4/5 patients with different combinations and degrees of mitral, tricuspid, and aortic valve involvement. Right atrial and ventricular dilation were seen in 4/5 patients; three patients had left atrial dilation. Three patients experienced atrial fibrillation, and one of these also experienced paroxysmal ventricular contractions. All patients underwent surgical repair, and some underwent multiple procedures. One patient who had previously undergone kidney transplantation died approximately 1 year postoperatively; the remaining four patients are currently experiencing good activities of daily living without symptoms., Conclusions: CS ASD (Kirklin and Barratt-Boyes type IV URCS) comprised 1.3% of adult congenital heart surgeries and 0.07% of adult open-heart surgeries at New Tokyo Hospital from 1999 to 2019. At New Tokyo Hospital, cardiac surgery is performed mainly for patients with acquired cardiac disease, and CS ASD is rare. Early diagnosis is important, as well as early surgical repair in symptomatic patients, especially those with blood access shunts, which may overload the heart. The case of a poor prognosis in this series is noteworthy, as similar cases have not been reported previously.

Background: Ductus venosus (DV) abnormalities may be associated with intracardiac or extracardiac deformities, chromosomal anomalies, and/or congestive heart failure. Aberrant DV connecting with the coronary sinus (CS) is rare and the prenatal diagnosis presents challenges for most examiners., Case Presentation: A 35-year-old pregnant woman, gravida 2, para 1, was referred to our center at 27 gestational weeks for a full evaluation of fetal cardiac anomalies. Transverse scans indicated normal cardiac anatomy except for a dilated CS; we then scanned sagittal planes to clarify the reasons for the CS dilatation. High-definition flow imaging (HDFI) together with radiant flow (R-flow) imaging was used to delineate the aberrant DV returning to the CS, enabling the diagnosis. Three-dimensional (3D) technology was also used to obtain color-rendered images showing the spatial relationships of the vessels involved, thus confirming the two-dimensional (2D) diagnosis. Chromosomal analysis revealed a normal karyotype. The neonate appeared healthy and the echocardiogram showed a normal cardiac anatomy except for a dilated CS with the DV closed and imperceptible., Conclusions: The aberrant course of the DV returning to the CS was clearly demonstrable by traditional 2D echocardiography using HDFI and the R-flow technique. We deem it helpful to trace the inflow of the dilated CS to make the differential diagnosis. The 3D modality might also provide additional spatial information on the associated vessels and thereby assist in prenatal diagnosis.

Background: Most reported cases of right anomalous coronary artery from the opposite sinus (R-ACAOS) have benign clinical outcomes. However, patients with left ACAOS (L-ACAOS) and some of the patients with R-ACAOS are more at risk for arrhythmias and sudden cardiac death, which remains a major concern. Here we report the prevalence and anatomical features of ACAOS patients. Moreover, we explore the high-risk morphological signs and evaluate their mid-term prognostic value in R-ACAOS patients without surgical intervention., Methods: Data from coronary computed tomography angiography (CTA) of 30,593 patients, pertaining to a single center over 5 consecutive years, were retrospectively analyzed. The image analysis included stenosis severity ranking and high-risk anatomy evaluation, based on the commercially available image post-processing software OsirX. Patients with R-ACAOS and without evidence of coronary atherosclerosis (CAD) were followed-up, with recording of the cardiovascular clinical events. Cox regression analysis was performed to identify the potential anatomical risk factors of cardiovascular clinical events for non-CAD R-ACAOS patients, using R project., Results: The prevalence of ACAOS in the study population was 0.69% (211/30593). Significant differences were found between patients with mild (< 50%) and severe (> 50%) stenosis, in terms of height-to-weight ratio (HW ratio), take-off angle, and proximal stenosis length. A total of 54 cardiovascular clinical events were observed among 108 non-CAD R-ACAOS patients and an average follow-up of 27.8 ± 18.7 months. Among those patients' anatomical features, stenosis severity was the main risk factor for cardiovascular clinical events during the mid-term follow-up, with a risk ratio of 4.14 (95% CI: 1.78 to 9.63, P < 0.001)., Conclusions: Among patients referred to coronary CTA, the overall incidence of ACAOS was 0.69%. For patients with R-ACAOS, severe stenosis was the independent risk factor of adverse clinical events in the mid-term follow-up, and positive clinical intervention might be needed to help them avoid the malignant clinical events.

Hypothyroidism is rarely included in the differential diagnosis for fetal sinus bradycardia. We report an infant with congenital hypothyroidism caused by ectopic thyroid tissue, who showed antenatal bradycardia. The baseline fetal heart rate was 100-110 bpm at 30 weeks of gestation, and fetal echocardiography revealed sinus bradycardia but no cardiac anomalies. Maternal thyroid function was normal (thyroid-stimulating hormone [TSH] 2.03 μIU/ml, free T3 2.65 pg/ml, and free T4 0.99 ng/dl) when measured at 31 weeks of gestation. Her serum anti SS-A and SS-B antibodies, anti-thyroglobulin, and microsomal antibodies were negative. A male infant without cardiac anomalies was delivered at 35 weeks and 4 days of gestation and admitted for prematurity and respiratory distress syndrome. The infant's heart rate was 70-110 bpm (normal: 120-160 bpm) on admission. On 8 days of age, thyroid function tests revealed that the infant had severe hypothyroidism (TSH 903.3 μIU/ml, free T3 1.05 pg/ml, and free T4 0.26 ng/dl). The prolonged jaundice assumed to be due to hypothyroidism. Oral levothyroxine sodium hydrate (10 μg/kg/day) was immediately started on day 8. After the treatment, the heart rate was gradually increased to 130-140 bpm as the infant's thyroid function was improved (TSH 79.8 μIU/ml, free T3 2.95 pg/dl, and free T4 1.66 ng/dl on day 22). The infant was diagnosed ectopic thyroid tissue because of the high thyroglobulin level (85.9 μg/l). In conclusion, congenital hypothyroidism should be included in the differential diagnosis in cases of fetal bradycardia without cardiac anomalies or maternal autoimmune diseases.

Coronary artery anomalies are usually an incidental finding on coronary angiogram. Most of them are benign, although few of them are malignant which may cause sudden cardiac death. A 64-year-old diabetic, hypertensive man underwent coronary angiography for evaluation of exertional dyspnoea, and angina which revealed an anomalous left main coronary artery (LMCA) arising from right coronary sinus which was unduly long (79 mm) but free from any disease. To the best of our knowledge after extensive search in literature, this is the longest LMCA to be ever reported. The patient was managed conservatively., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019. No commercial re-use. See rights and permissions.

Coronary artery fistula is a rare congenital cardiac anomaly. We report a 34-year-old woman who presented with a recurrent large pericardial effusion during pregnancy. She was found to have a right coronary artery to coronary sinus fistula. The coronary sinus was severely dilated due to coronary sinus ostial stenosis. Primary surgical closure of coronary artery fistula was performed with resection of coronary sinus ostial stenosis., (Copyright © 2019 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Left superior vena cava draining into the left atrium in the absence of coronary sinus is an anomaly that can appear in heterotaxy syndrome and unroofed coronary sinus syndrome. Regardless of the origin of these syndromes, biventricular repair can be done through rerouting by intracardiac procedures or through disconnection-reconnection of the left superior vena cava to the right atrium or right superior vena cava by extracardiac procedures. Different techniques can be used for this purpose, each of which has its own advantages and limitations. Therefore, appropriate selection is necessary to obtain the best results for each patient, and many factors, such as patient anatomy, age, associated cardiomyopathies, etc., have to be considered. In this review, we focus on heterotaxy and unroofed coronary sinus syndromes, associated cardiomyopathies, the state-of-the-art in their surgical treatment and our results in a sample of 10 patients. Our experience highlights the importance of accurate diagnosis and specific selection of surgical technique for the management of biventricular repair in patients with left superior vena cava draining into the left atrium in the absence of coronary sinus., (Copyright © 2018.

Objectives: Variations in coronary anatomy are common and may relate to the position of the coronary ostium relative to the aortic sinus, the angle of coronary take-off, or the course of the coronary arterial branches. Several classification systems have been proposed. However, they all lack a simple rationale that is applicable irrespective of the relative position of the great arteries, as well as in bicuspid aortic valves. We present a modification of a relatively simple system introduced in the early 1980s, designated the "Leiden Convention.", Methods: The first step of the Leiden Convention is that the clinician takes position in the nonfacing sinus of the aorta looking toward the pulmonary orifice. The right-hand facing sinus is sinus 1, and the left-hand facing sinus is sinus 2. The coronary branches arising from sinus 1 are annotated proceeding in a counterclockwise fashion toward sinus 2. "Usual" (normal) coronary anatomy would be 1R-2LCx. Given their clinical relevance, single sinus coronary arteries are discussed separately., Results: This system was originally designed and highly applicable in hearts with an altered great artery relationship, such as in the variable and complicated patterns seen in transposition of the great arteries and double outlet right ventricle. The modified system also can be used in cases with normally related great arteries, cases with single sinus coronary arteries, and cases with bicuspid aortic valves., Conclusions: The modified Leiden Convention is not a strict classification but a simple coronary coding system that is broadly applicable., (Copyright © 2018 The American Association for Thoracic Surgery.

Background: Intramural anomalous aortic origin of a coronary artery (AAOCA) is associated with an increased risk of sudden cardiac death. This is amenable to surgical coronary unroofing, but outcomes studies are lacking., Objective: To perform a comprehensive review of our institutional experience with pediatric patients with AAOCA who underwent surgical repair with unroofing of the intramural segment, focusing on preoperative and postoperative course and testing as well as intraoperative findings., Methods: A retrospective cohort study was conducted to evaluate patients with AAOCA status post-coronary unroofing at Children's Hospital of Wisconsin. Data extraction included symptoms, preoperative and postoperative imaging and testing, surgical findings, and postoperative clinical course., Results: From January 1999 to December 12, 2015, 63 patients underwent unroofing at a median age of 13 years (0.5-18 years). The majority underwent unroofing of an intramural right coronary (79%); 21% had an intramural left AAOCA. Symptoms suggestive of possible ischemia were present in about 50%. Additional structural cardiac anomalies were present in 33%. Transthoracic echocardiography was diagnostic in 60 of 63 (95%) and correlated with surgical findings in all cases. There was no surgical mortality associated with the unroofing, and no additional coronary reinterventions were performed. The median duration of postoperative follow-up was 3.1 years (7 days to 13.6 years). Symptoms either persisted or developed in 46% postoperatively. Postoperative exercise stress testing, stress echocardiography, and cardiac magnetic resonance imaging were performed in 76%, 8%, and 20%, respectively, of the cohort. None identified findings consistent with reversible coronary ischemia. Three patients had sudden cardiac arrest (1 death) after surgery without an identified residual coronary abnormality., Conclusions: Transthoracic echocardiography, with carefully designed coronary imaging protocols, can be diagnostic in accurately identifying intramural AAOCA in pediatric patients. Unroofing can be performed safely with no early morbidity, but symptoms can persist (including rare life-threatening events) without evidence of ischemia by postoperative provocative testing., (Copyright © 2017 The American Association for Thoracic Surgery.

A 54-year-old woman with a history of multiple cardiac surgeries suffered from hypoxemia caused by a right-to-left intra-cardiac shunt due to coronary sinus (CS) anomaly with persistent left superior vena cava (PLSVC). Both the contrast echocardiography and enhanced computed tomography (CT) provided conclusive diagnosis of this rare congenital anomaly, which was overlooked for a long time. However, an important diagnostic clue was left-arm injection of the contrast media. In the present case, previously performed enhanced CT with its routine manner, i.e., contrast through the right arm, missed this anomaly. It is crucial to note that the unusual type of unroofed CS with PLSVC, presenting with an entirely right-to-left intra-cardiac shunt, cannot be delineated on an enhanced routine chest CT if the contrast media is injected through the right arm.

We herein report a case of atrial tachycardia (AT) originating from the dilated coronary sinus (CS) connected to a persistent left superior vena cava. The earliest activation site of AT was localized at the superior CS ostium, identified using a novel ultra-rapid high-density mapping system (Rhythmia™). Successful ablation was performed at the corresponding position. This report demonstrated the utility of an ultra-rapid high-density mapping system in identifying arrhythmogenic foci in adult cases of congenital heart disease.

The anomalous origin of the right coronary artery from the left coronary sinus is a rare congenital disorder and can often result in sudden death upon initial presentation. We report a 19-year-old male patient who was referred to the Sultan Qaboos University Hospital, Muscat, Oman, in 2015 with multiple episodes of exertional angina. He was diagnosed as having an anomalous right coronary artery arising from the left coronary sinus following an intraoperative transesophageal echocardiogram. An unroofing ostioplasty of the anomalous right coronary artery was successful. Details of the surgical management of this anomaly are discussed.

Aims: Anomalous origin of a coronary artery from the opposite sinus (ACAOS) has been associated with adverse cardiac events in the young. It remains unknown whether this holds true for middle-aged patients with uncorrected ACAOS as well. We assessed the outcome in middle-aged patients with newly diagnosed ACAOS by coronary computed tomography angiography (CCTA) compared with a matched cohort., Methods and Results: We retrospectively identified 68 consecutive patients with ACAOS documented by CCTA. ACAOS with a course of the anomalous vessel between the aorta and pulmonary artery were classified as interarterial course (IAC). Each patient with ACAOS was matched to two controls without ACAOS. Major adverse cardiac events (i.e. myocardial infarction, revascularization and cardiac death) were recorded for all patients and controls. Two (3%) patients were lost to follow-up. Thus, 66 patients with ACAOS were included in the final analysis and matched with 132 controls. Mean age of patients was 56 ± 11 years, 73% were male and the mean follow-up was 49 months. Forty (65%) patients were classified as having ACAOS with IAC. The annual event rate of ACAOS vs. controls was 4.9 and 4.8%, the hazard ratio (HR) 0.94 (0.39-2.28, P = 0.89). The annual event rate of ACAOS with IAC compared with their matched controls was 5.2 and 4.3%, and the HR 1.01 (95% CI 0.39-2.58, P = 0.99)., Conclusions: In middle-aged individuals with newly diagnosed ACAOS mid-term outcome is not statistically different to a matched control cohort without coronary artery anomalies, regardless of whether ACAOS with or without IAC variants are present., (Published on behalf of the European Society of Cardiology.

Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-year-old male cadaver whose cause of death was determined as non-cardiac. The heart was examined and we found a PLSVC draining into the coronary sinus. The right superior vena cava was present with a small-diameter ostium. An anomalous pulmonary vein pattern was observed; there was a common trunk to the left superior and left inferior pulmonary veins (diameter 17.8 mm) and an additional middle right pulmonary vein (diameter 2.7 mm) with two classic right pulmonary veins. The PLSVC draining into the coronary sinus had led to its enlargement, which could have altered the cardiac haemodynamics by significantly reducing the size of the left atrium and impeding its outflow via the mitral valve.

Background: Congenital anomalies of the venous system are rare, involve the inferior vena cava (IVC), a persistent left superior vena cava (PLSVC), and the left hepatic vein (LHV), and can make cardiac diagnostic and therapeutic procedures difficult., Case Presentation: We present a 67-year-old woman without heterotaxy syndrome associated with interruption of the left IVC that continued with the hemiazygos vein system, a PLSVC, and an anomalous LHV draining the into coronary sinus (CS). The venous anomalies caused a CS aneurysm. The anomalies were demonstrated by echocardiography and the diagnosis was established by contrast-enhanced computed tomography. Three days later, a coronary artery bypass graft was performed, which confirmed the diagnosis. Half a month after surgery, the pain had been relieved and the patient was discharged from the hospital., Conclusion: Echocardiography is a useful modality to diagnose and assess anomalies of the CS, including CS aneurysms. Congenital anomalies of the venous system in this case were all due to embryonic development abnormalities. Contrast-enhanced computed tomography provides a more comprehensive view of the entire course of abnormal veins.

We report a rare causal association between obstructed supracardiac totally anomalous pulmonary venous drainage and coronary sinus ostial atresia. Our 12-week-old patient developed venous myocardial infarction secondary to coronary venous hypertension because her sole route of coronary venous drainage was obstructed. She recovered after the obstruction was relieved by balloon dilation. Surgical repair then included anastomosis of the pulmonary venous confluence to the left atrium, ligation of the vertical vein, and unroofing of the coronary sinus. Coronary sinus ostial atresia is rarely diagnosed before autopsy.

Coronary sinus atrial septal defect is a rare congenital cardiac anomaly in adults. Patients with this anomaly are generally treated using conventional sternotomy or thoracotomy incisions. However, robotic surgery can be a feasible alternative in this anomaly. We report an adult patient, who presented with coronary sinus atrial septal defect. A totally endoscopic robotic repair was successfully done through a right atriotomy approach in this patient., (© The Author 2016.
