Congenital heart defects are associated with various extracardiac malformations. Among them, association of congenital upper-limb malformations is common and frequently referred as heart–hand syndrome. Thumb malformations are most frequent among upper-limb malformations. The most common among them is Holt–Oram syndrome which consists of atrial septal defect with absent radius or thumb anomalies. Patent ductus arteriosus (PDA) with hand anomalies are quite rare. The authors present a peculiar hand deformity with PDA in a 2-month-old infant. The right hand revealed oligodactyly with syndactyly of the thumb and forefinger, the absence of carpal bones, few metacarpals, and phalangeal components.

| Introduction|| |
Heart–hand syndromes (HHS) refer to congenital heart defects with upper-limb malformations., There are several types of HHS, but the most common among them is Holt–Oram syndrome which consists of atrial septal defect with absent radius or thumb anomalies. Patent ductus arteriosus (PDA) is commonly associated with bicuspid aortic valve. In Char syndrome, PDA is associated with short or absent fifth finger and distinct facial features. The authors report PDA with peculiar hand anomaly with missing many components of hand and digits.
| Case Report|| |
A 2-month-old infant who came for immunization was found to have oligodactyly and syndactyly of the thumb and forefinger on the right side [Figure 1]. The digits on other three limbs were normal. X-ray of the right hand revealed the absence of carpal bones, few metacarpals, and components of phalanx [Figure 2]. Ash leaf macule measuring 2 cm × 3 cm was present around the umbilicus. Clinical examination did not reveal any other anomaly. His weight was 4315 g (between 3rd and 15th centiles), length was 54 cm (<3rd centile), and head circumference was 37.5 cm (between mean and −2 SD). The pulse was 150/min and bounding type. The respiratory rate was 40/min. The cardiovascular system examination revealed normal apical impulse and continuous murmur at the left infraclavicular area. Per abdominal examination revealed hepatomegaly of 3 cm. Another system examination was normal. Complete blood count and serum creatinine were normal. Chest radiograph was normal. There were no vertebral anomalies. Echocardiography revealed normal cardiac segmental anomaly, moderate PDA measuring 4 mm with left-to-right flow. The peak gradient was 25 mmHg. Biventricular structure, size, and systolic function were normal. Electrocardiography was normal. Ultrasonography of the abdomen and renal scan were normal. Exome sequencing or chromosomal microarray could not be done in view of financial constraints.

He was born to a 28-year-old woman at 37 weeks by elective cesarean section with a birth weight of 2475 g. Maternal history revealed four prior abortions between 5 and 12 weeks. The recurrent pregnancy loss (RPL) workup showed a normal anti-Mullerian hormone level. Coagulation profile was normal. Couple karyotyping done was normal. Anti-beta-2-glycoprotein IgM was positive. The mother received enoxaparin and aspirin antenatally. The baby was started on furosemide drops, and hand reconstruction was planned by a hand surgeon.
| Discussion|| |
A group of rare diseases that manifest with both heart and limb deformities are called HHS., They are classified into at least six distinct types. Type 1 is commonly known as Holt–Oram syndrome. It is the most prevalent form of HHS. It is an autosomal dominant disorder with absent radius on both sides, atrial septal defect, and a first-degree heart block. HHS type 2 is known as Berk–Tabatznik syndrome. The syndrome includes short stature, congenital optic atrophy, brachytelephalangy, and hypoplasia of distal phalanges. HHS type 3 is described as Spanish type. The syndrome consists of cardiac conduction defects and brachydactyly. HHS, Slovenian type, is characterized by unique brachydactyly with mild hand involvement and severe foot involvement. Cardiomyopathy and sudden cardiac death may be the associated features. Brachydactyly-long thumb syndrome is known to have symmetric brachydactyly with long thumbs. There may be associated cardiac conduction defects. PDA-bicuspid aortic valve syndrome is a distinct syndrome with brachydactyly and metacarpal hypoplasia of the fifth finger. It resembles Char syndrome which consists of PDA, fifth finger middle phalangeal hypoplasia, and minor facial anomalies. The present case had PDA with peculiar hand involvement on only one side. There was no facial feature.
The hand anomalies have also been classified into five categories: (I) failure of formation of parts, (II) failure of differentiation of parts, (III) duplication, (IV) overgrowth, (V) undergrowth, and (VI) congenital constriction band syndrome.
In the present case, the mother underwent workup for RPL and was found to be positive for anti-beta-2-glycoprotein IgM antibodies. This could be the probable cause for RPL., It is, however, difficult to establish the link between hand anomalies with anti-beta-2-glycoprotein antibodies in the mother. There was no family history of hand anomalies. The present case represents the extended spectrum of HHS.
