A 65-year-old male presented with chest pain that occurred after alcohol drinking at the early morning hours and relieved after taking sublingual nitroglycerin. Coronary angiography revealed a malformed left main coronary artery (LMCA) originating from the right sinus of Valsalva with 10%–20% stenosis and 80% vasospasm. Coronary artery spasm (CAS) in the LMCA is extremely rare but can present with catastrophic features. CAS is more frequently observed in atherosclerotic segments of coronary arteries, and multidetector computed tomography is preferred for assessing the degree of atherosclerosis in cases of LMCA spasm. Anomalous origin of coronary arteries (AOCA) is also rare but can lead to severe symptoms. Although surgical intervention is generally recommended for symptomatic patients, while management of asymptomatic cases remains a topic of ongoing research and debated. In this case, there was concern that the patient’s symptoms might be attributable to AOCA or CAS, medical management was selected over surgical intervention, given the presentation consistent with typical angina due to spasm.

Background: and Objective: We aimed to investigate long-term clinical and echocardiographic outcomes, including tricuspid valve durability, annular growth, and left ventricular reverse remodeling, after modified cone reconstruction in patients with Ebstein’s anomaly. Methods: This was a retrospective analysis of all pediatric patients who underwent modified cone reconstruction for Ebstein’s anomaly at a single tertiary center between January 2005 and June 2021. Results: A total of 14 pediatric patients underwent modified cone reconstruction for Ebstein’s anomaly; the median age was 5.8 years (range, 0.01–16.6). There were three patients (21.4%) with Carpentier type B, ten patients with Carpentier type C (71.4%), and one patient with Carpentier type D (7.1%). There was no early or late mortality, arrhythmia, or readmission for heart failure at a 10-year follow-up. There were no cases of more than mild tricuspid stenosis or more than moderate tricuspid regurgitation during the study period, except for one patient with severe tricuspid regurgitation who underwent reoperation. The z value for tricuspid valve annular size significantly decreased immediately after the operation (2.46 vs. −1.15, p<0.001).However, from 1 year to 7 years after surgery, the z values were maintained between −1 and +1.Left ventricular end-systolic volume, end-diastolic volume, and stroke volume increased after surgery and remained elevated until seven years postoperatively. Conclusions Ebstein’s anomaly in children can be repaired by modified cone reconstruction with low mortality and morbidity, good tricuspid valve durability, and annular growth relative to somatic growth.

Partial anomalous pulmonary venous return (PAPVR) is a rare congenital cardiac anomaly that can be difficult to detect and often remains undiagnosed. PAPVR is diagnosed using non-invasive imaging techniques such as echocardiography, CT, and MRI. Image data are reviewed on a 2-dimensional (D) monitor, which may not facilitate a good understanding of the complex 3D heart structure. In recent years, 3D printing technology, which allows the creation of physical cardiac models using source image datasets obtained from cardiac CT or MRI, has been increasingly used in the medical field. We report a case involving a 3D-printed model of PAPVR with a biatrial connection. This model demonstrated separate drainages of the right upper and middle pulmonary veins into the lower superior vena cava (SVC) and the junction between the SVC and the right atrium, respectively, with biatrial communication through the right middle pulmonary vein.

A 59-year-old man presented for possible durable ventricular assist device (VAD) implantation. He had previously been diagnosed with congenitally corrected transposition of the great arteries, a ventricular septal defect, an atrial septal defect, pulmonary valve stenosis, and aortic valve regurgitation. In the previous 22 years, he had undergone palliative cardiac surgery 3 times. VAD implantation as a bridge to transplantation was planned. Owing to severe adhesions, mesocardia, a left ascending aorta, and moderate aortic regurgitation, we performed VAD implantation and aortic valve closure via a dual left thoracotomy and partial sternotomy.

Here we present a rare case of pulmonary arterial thrombosis associated with a ductus arteriosus aneurysm that caused severe pulmonary stenosis. A 5-day-old newborn was admitted to our hospital for the evaluation of an intracardiac mass-like lesion found after the detection of a cardiac murmur. Echocardiography and heart computed tomography revealed a mass-like lesion measuring 8.1 mm in diameter across the distal main pulmonary artery to the proximal left pulmonary artery resulting in localized severe stenosis of the left pulmonary artery. Left pulmonary artery angioplasty for surgical resection of the thrombus revealed that the mass was adherent to the proximal part of the left pulmonary artery anterior wall and extended to the ductus arteriosus. Histological examination of the mass showed an old thrombus with dystrophic calcification. Five months after surgery, follow-up echocardiography showed that the left pulmonary artery peak pressure gradient had decreased but the proximal left pulmonary artery stenosis remained. Cardiac catheterization and balloon angioplasty suc cessfully relieved the pulmonary stenosis.

BACKGROUND: This study aimed to determine the effect of a multidisciplinary approach on the birth rate of fetuses with prenatally diagnosed congenital heart diseases (CHDs). METHODS: Among the fetuses of 724 gravidas who underwent fetal echocardiography in Samsung Medical Center from January 2013 to June 2017, 463 fetuses with normal cardiac structure, arrhythmia or simple left-to-right shunt were excluded, and the remaining 261 were included in the study. The subjects were subdivided into groups based on whether they were consulted multidisciplinarily, that is, consulted simultaneously by pediatric cardiologists, obstetricians and pediatric cardiac surgeons or not. They were also categorized based on the initial fetal echocardiogram results. RESULTS: Among the fetuses in the multidisciplinary group, 64.5% of the fetuses were given birth to, and the proportion was not different from that in the non-multidisciplinary group (68.6%, P = 0.48). The delivery rate in the multidisciplinary consultation group were 69.2% in the transposition of the great arteries group, 63.6% in the tetralogy of Fallot group, 68.8% in the pulmonary atresia or interrupted aortic arch group, 62.5% in the coarctation of aorta group, 60.0% in the atrioventricular septal defect group, 70.0% in the functional single ventricle group, and 55.6% in the hypoplastic left heart syndrome group; there were no significant differences between the 10 echocardiogram groups. However, when the subjects were categorized into Fontan repair group and biventricular repair group, the Fontan repair group showed a significant increase in the likelihood of delivery when a multidisciplinary approach was taken (P = 0.035). CONCLUSION: When a fetus was diagnosed with a CHD where Fontan repair should be considered, a multidisciplinary approach resulted in increased possibility of delivery.

This case report concerns a young patient with an extremely rare combination of d-transposition of the great arteries (d-TGA) and anomalous origin of the right subclavian artery. In our patient, the right subclavian artery originated from the pulmonary artery, which is why he did not show reversed differential cyanosis. We conclude that the presence of an aortic arch anomaly should be considered in patients with d-TGA who do not present with reversed differential cyanosis. A further imaging work-up, including computed tomography or magnetic resonance imaging, might be helpful.

BACKGROUND AND OBJECTIVES: The aims of this study were to determine the early and late outcomes of anatomic repair of congenitally corrected transposition of the great arteries (ccTGA) and to evaluate effectiveness of the hemi-Mustard procedure. SUBJECTS AND METHODS: We conducted a retrospective, single-center study of patients who underwent anatomic repair for ccTGA between July 1996 and December 2013. Sixteen patients were included in the study. The median age at the time of the operation was 3.5 years (range: 0.5-29.7), and the median body weight was 13.3 kg (range: 5.8-54). The median follow-up duration was 7.7 years (range: 0.2-17.4). RESULTS: Atrial switch was achieved using the Mustard procedure in 12 patients (hemi-Mustard procedure in 11) or the Senning procedure in four patients. The ventriculoarterial procedure was performed using the Rastelli procedure in 11 patients and arterial switch in five patients. Six patients underwent tricuspid valvuloplasty. The survival rate was 93.8±6.1%. The rate of freedom from reoperation at 5 years was 92.3±7.4% in the Rastelli group. All patients except one were New York Heart Association class I. All patients except one had mild tricuspid regurgitation. CONCLUSION: Anatomic repair can be performed with a low risk of in-hospital mortality. The hemi-Mustard strategy for selected patients is one solution for reducing early mortality and morbidity, and long-term complications such as venous pathway stenosis or sinus node dysfunction.

BACKGROUND AND OBJECTIVES: We investigated the effectiveness of balloon dilatation of homograft conduits in the pulmonary position in delaying surgical replacement. SUBJECTS AND METHODS: We reviewed the medical records of patients who underwent balloon dilatation of their homograft in the pulmonary position from 2001 to 2015. The pressure gradient and ratio of right ventricular pressure were measured before and after the procedure. The primary goal of this study was to evaluate the parameters associated with the interval to next surgical or catheter intervention. RESULTS: Twenty-eight balloon dilations were performed in 26 patients. The median ages of patients with homograft insertion and balloon dilatation were 20.3 months and 4.5 years, respectively. The origins of the homografts were the aorta (53.6%), pulmonary artery (32.1%), and femoral vein (14.3%). The median interval after conduit implantation was 26.7 months. The mean ratio of balloon to graft size was 0.87. The pressure gradient through the homograft and the ratio of right ventricle to aorta pressure were significantly improved after balloon dilatation (p<0.001). There were no adverse events during the procedure with the exception of one case of balloon rupture. The median interval to next intervention was 12.9 months. The median interval of freedom from re-intervention was 16.6 months. Cox proportional hazards analysis revealed that the interval of freedom from re-intervention differed only according to origin of the homograft (p=0.032), with the pulmonary artery having the longest interval of freedom from re-intervention (p=0.043). CONCLUSION: Balloon dilatation of homografts in the pulmonary position can be safely performed, and homografts of the pulmonary artery are associated with a longer interval to re-intervention.
