“…We observed variations in the shape of FOv as oval being most common in 40 (80.0%), circular in 8 (16.0%), and elliptical in 2 specimens (4.0%) ( Fig. 5 ), which were similar to findings of Joshi et al [ 22 ]. The average transverse diameter of FOv observed in our study was 24.21 mm (range, 12–26 mm) and the average vertical diameter was 26.84 mm (range, 14–28 mm).…”

“…Studies say that these fibrous networks may be formed due to incomplete overlap and atrophy of various embryological components of the interatrial septum. Similar fibrous bands were observed in one heart specimen in a study [ 22 ] and 7.4% cases (out of 135 heart specimens) in another study on interatrial septum [ 29 ]. This network of fibrous bands may interfere during transseptal catheter insertion.…”

“…The average transverse diameter of FOv observed in our study was 24.21 mm (range, 12–26 mm) and the average vertical diameter was 26.84 mm (range, 14–28 mm). Whereas the dimensions observed by Kydd et al [ 23 ] were anteroposterior 17 mm and supero-inferior 19.4 mm and other authors observed the average transverse diameter to be 14.53 mm and average vertical diameter to be 12.60 mm [ 22 ].…”

“…The limbus was prominent all around the margin in 14%, anterosuperior in 12%, anterior, superior, and inferior in 26 heart specimens (52%). In a study by Joshi et al [ 22 ], the limbus was raised all-round in 92% cases and flat in 4% cases. Naqvi et al describe the formation of limbus FOv in their article that during the 7th week of development remodeling occurs in the atrial roof between the septum primum and the superior cava [ 24 ].…”

Atrial septal defect (ASD) is the 5th common congenital abnormality at birth. Secundum atrial defect and patent foramen ovale (PFO) are the most common atrial septal defects. In this setting, the anatomical functional characterization of the interatrial septum seems to be of paramount importance not only for device selection but also for therapeutic intervention. This study was carried out to evaluate the morphometric parameters of fossa ovale (FOv) in the human adult cadaveric hearts. For this study, 50 normal cadaveric human hearts available in the department of Anatomy over the period of 3 years were used where size, position, shape, nature of the FOv was noted. The size of the fossa was measured and prominence, location, and extent of the limbus fossa ovalis were observed. The probe patency of foramen ovale (FO) was confirmed. In most specimens, the fossa was oval (80%), the average transverse diameter was 24.21 mm, and the vertical diameter 26.84 mm. In 84% rim was raised. In 56% of cases, the fossa was present at the middle of the interatrial septum. The patency of foramen was observed in 3%. The findings of the present study provide pertinent information on the morphology of the FOv, which may be useful for device selection in treating ASDs and PFO. This would definitely help the clinicians in a deeper understanding of the region as very few cadaveric studies are available in the literature at present.

“…The middle cardiac vein, draining a part of the left and right ventricle, runs via the subsinuosal interventricular groove and enters the coronary sinus near its ostium, or drains directly into the right atrium (Figure 1). 14,15 The oval fossa is the oval depression in the interatrial septum, seen from the right atrium 17 . The limbus is defined as the muscular ridge around the oval fossa, of which the dorsocranial part is most pronounced (Figure 2).…”

Background: Arrhythmias are common in horses, but catheter-based minimally invasive electrophysiological studies and therapeutic interventions have been poorly explored in equine medicine, partly due to the lack of detailed anatomical knowledge of the equine heart.Objectives: To describe the dimensions and anatomical features of some electrophysiologically important landmarks of the right atrium in detail and assess their correlation with bodyweight and aortic diameter. Study design: Ex vivo cadaveric study.Methods: Twenty-one hearts of Warmblood horses, subjected to euthanasia for noncardiovascular reasons, were examined post-mortem. The dimensions and anatomical features of the coronary sinus, the great cardiac vein and the oval fossa were recorded. Spearman's Rho correlation coefficients were calculated for correlations between the quantitative parameters and bodyweight and aortic diameter.Results: Median dimensions for coronary sinus, great cardiac vein and oval fossa were obtained. A Thebesian valve, partially covering the ostium of the coronary sinus, was present in 9 of the 21 hearts. A median of 6.5 (range 4-9) valves were present in the great cardiac vein. Several parameters, among which the dimensions of the oval fossa and the length of the great cardiac vein, were significantly positively correlated with bodyweight and aortic diameter.Main limitations: Measurements do not consider the dynamic changes during the cardiac cycle as measurements were performed ex vivo. All specimens were retrieved from Warmblood horses, therefore measurements might not apply to other breeds. Conclusions:This study delivers a detailed description of important right atrial-related structures, necessary for the development of minimally invasive intracardiac procedures in horses. Adequate imaging techniques will have to be explored in order to guide these procedures.

BackgroundThe development of new trans‐septal transcatheter interventions for patients with structural heart disease necessitates a precise and comprehensive understanding of the anatomy of the interatrial septum (IAS). The scarcity of gross anatomical studies has triggered our interest in exploring the morphometry and morphology of IAS.AimsTo study the morphology, morphometry and variations of the interatrial septum in autopsied human hearts.MethodsThe study was conducted on 97 autopsied fresh human hearts, in which we observed the position and shape of fossa ovalis (FOv), along with prominence of the limbus and its location. The diameter of FOv, thickness of its floor, redundancy and any variation in the IAS were noted.ResultsIn most cases (72.9%), the FOv was situated toward the inferior vena cava and was oval shaped (69.8%), with mean horizontal and vertical diameters of 17.21 ± 4.11 mm and 12.74 ± 3.78 mm, respectively. The limbus was prominent in 72.2% specimens, most commonly prominent all around (36.6%), followed by antero‐superior (28.2%), antero‐inferior (16.9%) and anterior (8.5%) prominence. The mean thickness of the floor of FOv was 0.71 ± 0.98 mm, and redundancy was observed in 47% of samples. Probe patency was seen only in 10.3% specimens. The right surface of the IAS showed more variations (71.1%) compared to the left (44.3%), in form of recesses, atrial septal pouches, fibrous strands, retinacular‐type fibrous networks and combination of more than one type.ConclusionVariations in the location of FOv, the prominence of limbus and the common occurrence of anatomical variants of the IAS mandate the preprocedural imaging of the region to reduce the failure rate and complications.
