It is characterized by a single arterial trunk that forms the outlet for both HEART VENTRICLES and gives rise to the systemic, pulmonary, and coronary arteries. It is always accompanied by a ventricular septal defect.Truncus Arteriosus: The arterial trunk arising from the fetal heart. During development, it divides into AORTA and the PULMONARY ARTERY.Foramen Ovale: An opening in the wall between the right and the left upper chambers (HEART ATRIA) of a fetal heart. Oval foramen normally closes soon after birth; when it fails to close the condition is called PATENT OVAL FORAMEN.Heart Valves: Flaps of tissue that prevent regurgitation of BLOOD from the HEART VENTRICLES to the HEART ATRIA or from the PULMONARY ARTERIES or AORTA to the ventricles.Copyright: It is a form of protection provided by law.

Morphological basis for the study of the interatrial septum in the human fetus. (1/81)

OBJECTIVE: To describe morphological features of the interatrial septum in normal fetuses, especially foramen ovale (FO) and septum primum (SP), in order to compare septum primum excursion with foramen ovale diameter. METHODS: Septum primum excursion (SPE) toward the left atrium (LA) and foramen ovale diameter (FOD) were measured in the hearts of ten formaldehyde-fixed human fetuses ranging from 28 to 36 weeks of gestation. Histological sections were obtained from the foramen ovale (FO), septum primum (SP), septum secundum (SS), left atrium (LA), and right atrium (RA). RESULTS: FOD and SPE measurements were the following: FOD 3.1-3.5 mm and SPE 2.8-3.1 mm in three fetuses with presumed gestational age (GA) of 28 weeks; FOD 3.3-3.5 mm, and SP excursion 4.0-5.0 mm in four fetuses with presumed GA of 34 weeks, plus FOD 3.3-4.5 mm and SPE 6.0-9.0 in three fetuses with presumed GA of 36 weeks. Cardiac muscular fibers were identified in both the septum primum and secundum. CONCLUSION: Based on its muscular components, it may be suggested that SP is active in character, influencing blood flow through the FO, SP mobility, and its excursion into the LA.  (+info)

Migraineurs with patent foramen ovale have larger right-to-left shunt despite similar atrial septal characteristics. (2/81)

The objective of the study was to assess differences in proportion of large right-to-left shunt (RLS) and atrial septal characteristics between migraineurs and non-migraineurs referred for transcatheter closure of patent foramen ovale (PF0). This retrospective study took place in a large metropolitan medical centre. The patients were migraineurs with aura (n=52), migraineurs without aura (n=19) and non-migraineurs (n=149). RLS was evaluated before closure using bilateral power m-mode transcranial Doppler at rest and after calibrated, sustained Valsalva manoeuvre, and graded with a validated 0-5 scale. Intracardiac echocardiography was used to assess atrial septal characteristics. Migraineurs had a higher proportion of large RLS (Grade IV or V) than nonmigraineurs at rest and after calibrated Valsalva (rest, p=0.04; Valsalva, p=0.01). Atrial septal characteristics were similar between groups. Migraine is associated with larger RLS at rest and strain; however migraine status does not predict PFO characteristics.  (+info)

Completely endoscopic removal of a dislocated Amplatzer atrial septal defect closure device. (3/81)

Surgical treatment of residual shunts after transcatheter occlusion of atrial septal defect or patent foramen ovale is reported in approximately one to two percent of these percutaneous interventions. Minimally invasive surgery on the atrial septum is getting more and more common but little data is available on Amplatzer device explantation through limited access. No completely endoscopic device removal has been described previously. We report a case of a 57-year-old woman in whom an Amplatzer device was removed in a robotic totally endoscopic fashion through ports only using the daVinci telemanipulation system.  (+info)

The structure and components of the atrial chambers. (4/81)

We discuss the implications of accurate knowledge of the human atrial chambers for those seeking to model atrial structure, and correlate the muscular activity with electrical signals. We stress first the importance of describing atrial components in attitudinally appropriate fashion, a feature sadly ignored by generations of morphologists. When considered relative to the body, the right atrium is positioned anteriorly relative to its alleged left-sided counterpart. We then described how each atrium possesses a venous component, an appendage, a vestibule, these parts being supported by the body of the atrium, and how the two chambers are separated by the septum. We extend this information by describing the detailed structure of each atrium, and then emphasise that it is only the floor of the oval fossa, and its antero-inferior rim, that are true septal structures. The so-called 'septum secundum' is the superior interatrial fold. Emphasis is then given to the muscular connections between the atriums, these unions obviously underscoring the potential for interatrial conduction. We then continue by discussing the structure of the atrial walls, which vary markedly in their thickness. It is the alignment of the myocytes within these walls that determines the velocity of conduction through them. In this setting, we also discuss the morphological features that distinguish between working myocytes and the myocytes of the conduction system, stressing the importance of rules established almost 100 years ago.  (+info)

Septal atrial pacing for the prevention of atrial fibrillation. (5/81)

AIMS: Atrial fibrillation (AF) produces significant morbidity and mortality. The current method of permanent pacing of the right atrium (RA) may cause delayed interatrial conduction and predispose to AF. We hypothesized that atrial septal pacing would reduce AF compared with high RA pacing. METHODS AND RESULTS: The patients were randomized into two groups. After randomization, patients received a dual-chamber rate-responsive device capable of mode-switching with advanced telemetry features. Devices were programmed in a standardized manner. To be eligible, the patients were required to have a conventional indication for a permanent pacemaker and recurrent paroxysmal AF. Group 1 was paced from high RA and Group 2 was paced from the atrial septum. Analysis of 43 patients who have completed 6 months of follow-up and 22 patients who completed 12 months of follow-up showed no significant differences in the number of mode-switching episodes or in AF burden between groups (P = NS by Mann-Whitney) although there was a trend for less AF with septal pacing. There were no differences in thresholds, sensing, or lead impedance. Lead parameters remained stable over time and there were no displacements of the electrodes after implantation. No patient experienced lead-related complications. A significant variability in AF burden was noted in this patient population. CONCLUSIONS: Implantation of an atrial-active fixation lead on the atrial septum is safe and feasible. However, this study showed no significant difference between septal pacing and high atrial pacing, using the endpoints of AF duration and number of AF episodes.  (+info)

Results TTE at 1 month showed persistent iASD in 57% (1M-iASD). Mean LA pressure after clip was significantly higher in patients with 1M-iASD than patients without 1M-iASD (17±6 mm Hg vs 15±5 mm Hg, p=0.01). Among patients with 1M-iASD, 24 patients (35%) had persistent iASD at 12 months (12M-iASD). Mean LA pressure after clip was significantly higher in patients with 12M-iASD than patients without 12M-iASD (19±6 mm Hg vs 16±6 mm Hg, p=0.04). Patients with 12M-iASD did not significantly differ from patients without 12M-iASD in terms of right heart enlargement, estimated systolic pulmonary artery pressure, New York Heart Association functional class and brain natriuretic peptide at 12 months. Logistic regression analysis, however, showed that mean LA pressure after clip was significantly associated with persistent iASD at 12 months in patients with 1M-iASD even after adjustment for cardiac index after clip and the prevalence of mitral regurgitation ≥3+ at 12 months (OR 1.10 per 1 mm Hg, 95% ...

Is it time for urologists to begin to rethink the radical cystectomy and begin to explore trimodality therapy? Maybe - maybe not - it depends on who you ask. Lets go over a few things first, though, before we jump right in.. (TMT) Trimodality Therapy is not some radical new line of treatment. The "Tri" stands for three "modalities" of treatment: chemotherapy, radiotherapy, and surgery. And again, while nothing new, the treatments used in combination to fight bladder cancer are a course of treatment that allows the patient to keep their bladder rather than have it removed.. (RC) Radical Cystectomy is typically the removal of the entire bladder, lymph nodes in proximity to the bladder, part of the urethra, and any organ tissue in proximity that does or could have cancerous cells.. For women, it can - but not always - entail uterus, ovaries, fallopian tubes, and part of the vagina being removed.. For men, it can - but not always - entail prostate, seminal vesicles, part of the vas deferens being ...

The echocardiographic features of congenital left ventricular inflow obstruction are described in six patients. The echocardiograms in two patients with cor triatriatum were distinguished by normal mitral valve motion and an abnormal echo within the left atrium. In two patients with supravalvar mitral ring, in addition to abnormal mitral valve motion, an abnormal echo, presumably originating from the obstructive membrane, was located between the anterior and posterior mitral leaflets. In two cases of parachute mitral valve, mitral valve motion was abnormal. In one of these cases there were multiple mitral valve echoes similar to those found in supravalvar mitral ring. The echocardiographic identification of an obstructive membrane within the left atrium is difficult because of the occurrence of artifacts. However, membranes may be identified if careful scanning techniques are employed in patients in whom left ventricular inflow obstruction is suspected. The echocardiogram is useful in detecting ...
Aneurysms of the interatrial septum are rare. They have been associated with complications such as embolic phenomena and atrioventricular orifice obstruction. We describe two patients, one adult and one child, with atrial septal aneurysms that were diagnosed by real-time, two-dimensional echocardiography. Atrial septal aneurysms appeared as thin, localized outpouchings of the atrial septum that protruded into the right atrium and showed marked variations in their contour and size during the cardiac cycle. They could be differentiated from other intra-atrial structures such as tumor mass, large eustachian valve and intra-atrial baffle by their relatively low reflectance, relationship to the atrial septum, considerable alterations in their outline during the cardiac cycle and characteristic patterns during peripheral venous contrast echocardiography. ...

Cardiac Catheterization in Children What is a cardiac catheterization? Cardiac catheterization is a specialized procedure in which a long, flexible tube (catheter) is inserted into a vein and guided into the heart, allowing a close look at the structures inside. It may also be performed for the following reasons: to obtain diagnostic information, such as pressures and oxygen saturations in various parts of the heart to obtain cardiac tissue samples for biopsy to open the atrial septum in congenital (pre...
Our work here has been most fascinating. We are trying the use of left heart bypass for acute left heart failure. It is much simpler than trying to use an oxygenator too, and I have learned to put a cannula down the jugular, on man or the dog, with relative ease, through the atrial septum, and into the left atrium for the purpose. Angiocardiograms with dogs have shown that in this fashion we are able to run bypass effectively enough so that no blood at all passes into the left ventricle, and the aorta fills only in retrograde fashion from the cannula in the femoral artery. Of 10 dogs run in this fashion for 24 hours, nine are long-term survivors, and the 3 which died were lost from silly technical errors, such as burning the dog with a hot pad. Oxygen utilization studies have shown that such a measure cuts the use as measured from the coronary sinus-aorta A-V difference and sinus flow rate to about 40% of control values.

Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation. A rare case of multivesicular interatrial septum hydatid cyst with multiple pulmonary involvement in a native Italian farm labourer is reported. Clinical, radiological, serological and histological findings are described. MR imaging showed the exact anatomic location and the multivesicular nature of the cardiac cyst and was useful in planning surgical treatment. A successful outcome was achieved with a combination of pre- and post-operative albendazole therapy and a three-step surgery procedure. The patient made a rapid recovery and his post-operative period was totally uneventful. This case highlights the importance of an early multidisciplinary surgical approach and long-term chemotherapy treatment of this serious and rare
Swedish pioneered the PFO treatment, which involves using a special device - a tiny, double-umbrella apparatus - to seal a small congenital defect in the heart known as a patent foramen ovale (PFO). A PFO results from incomplete closure after birth in the atrial septum, which is a thin wall separating the upper chambers of the heart. It has been implicated as a potential cause for unexplained strokes in young adults. Repairing the defect may therefore reduce the patients future stroke risk.. Like PFO, an atrial septum defect (ASD) results from incomplete closure after birth in the wall between the left and right atria. About 7 percent of congenital heart defects fall into this category, and if the defect is large enough, oxygen-rich blood from the left atrium flows back into the right side of the heart and is pumped back to the lungs instead of to the rest of the body. This results in more work for the heart. Patients with large ASDs experience shortness of breath with physical exertion. ...

1. Last Wednesday we had an appointment for BB#2 at a pediatric cardiology private practice.. 2. He was upset at first, but this time the office and the doctor were more relaxing, there were stuffed animals and the doctor tried to calm him down, and referred to his heart beat, as a "frog" so she tried to amke it interesting for him.. 3. So finally he calmed down enough and she could do an echocardiogram and an electrocardiogram! Hurray!

He had a PDA :Failure of a childs DA (ductus arteriosus) to close after birth. So now it looks like for sure his DA has closed all by it self! Hurray!. The last doctor also said he might have a Sinus venosus atrial septal defect, which is a deficiency of the atrial septum. But during this echocardiogram this Cardiologist said his atrial septum is intact, so ALL GOOD! I was soooooo glad to ...

Its 2018 and as I get older, Im starting to veer towards the conclusion that people are becoming desensitized to gratitude. As a whole, were becoming less thankful for the things we have and were always striving to have more. I dont see goals and dreams as a bad thing but if we cant be content with the beautiful things currently in our lives, how can we be content with lovely things, that are yet to come?. Last year, my brother, a London based, commercial finance consultant, was diagnosed with an extremely rare, congenital heart defect called Cor Tritriatum. The congenital heart condition accounts for an incredibly small percentage of the population in the United States and equates to 0.1-0.4%, of infants with congenital heart diseases.. To summarize it briefly, the human heart is divided into four chambers and two of those, are the atria. The two atria are separated from one another by a fibro-muscular wall of tissue, called the atrial septum. The ventricles are the other two chambers of ...

The invention describes a system, method, and means for an MRI transseptal needle that can be visible on an MRI, can act as an antenna and receive MRI signals from surrounding subject matter to generate high-resolution images and can enable real-time active needle tracking during MRI guided transseptal puncture procedures.
A buffer overflow or overrun is a memory safety issue where a program does not properly check the boundaries of an allocated fixed-length memory buffer and writes more data than it can hold. This causes data to overflow to adjacent memory space, overwriting the information there, which often leads to crashes and exploitable conditions.

To our knowledge this is the first description of aortic root perforation by a septal occluder in a patient with Marfan syndrome. There are only a few cases that report destruction of aortic segments after placement of closure devices in patients with patent foramen ovale (PFO), patent ductus arteriosus (PDA) or ASD [4-7]. Perforation is a rare event, occurring in approximately 0.1% of all cases, indicating closure devices are generally safe. The mechanism of perforation is not well understood but it might be related to the absence or presence of the anterosuperior and posteroinferior rims of the atrial septum where the closure device is fixed in position [8, 9]. Interestingly perforations are observed uniquely in the anterosuperior wall and the adjacent aorta [10].. In patients with an altered connective tissue, the reason for dislocation of closure devices might be different. Thus far, we know that the affected protein Fibrillin in Marfan syndrome, plays a crucial role in maintaining the ...
We describe a case of 43-year-old man with transcatheter closure of atrial septal defect (ASD) with the Amplatzer Septal Occluder that was embolized to the main pulmonary artery. Echocardiography could not identify the occluder device at the interatrial septal position. Tomography confirmed its dislocation (Figure 1). Silent device dislodgement which is a rare complication in terms of being asymptomatic was managed immediately. It was removed via pulmonary arteriotomy (Figure 2A and B) and the ostium secundum ASD without inferior rim was closed by using an autologous pericardial patch on total cardiopulmonary bypass. His postoperative period was uneventful.. Key words: Device Removal; Heart Septal Defects, Atrial; Septal Occluder Device ...
TRAVERSE-LA is the first randomized comparison of an RF versus conventional needle for transseptal puncture. The RF needle significantly reduced time to transseptal LA access, resulted in less failure of the assigned needle, and produced fewer visible plastic shavings from introduction of the needle through the dilator and sheath. Procedural complications did not differ between needle groups.. Transseptal puncture for LA access is becoming more common because of the growing adaptation of catheter ablation and structural heart procedures involving left-sided access.1-7 However, the transseptal puncture procedure can be time consuming13-14 and can result in important complications.15-16 Prolonged transseptal procedures may increase total procedure times and ionizing radiation exposure to the patient and operator because of the high-intensity fluoroscopy that is often employed. Finally, personnel and electrophysiology laboratory time may become both clinically and financially relevant at the ...

Background: Targeted transseptal (TS) puncture is essential for structural heart interventions. Spatial accuracy of standard versus RF needle has not been reported. Methods: Consecutive patients undergoing structural heart interventions requiring TS puncture were studied retrospectively. A standard needle was alternated with a RF needle. Procedural success and times were recorded. Measurements based on intraprocedural transesophageal echocardiograms of the intended versus final TS crossing site were obtained. Pre-puncture ...
The present study has several limitations. First, electrograms from the region of Kochs triangle were recorded simultaneously only from two atrial sites (i.e., the His bundle recording site and the CS orifice), and simple broad anatomic terms (anterior, middle and posterior) were used to define the anatomic sites of the atrial septum. More detailed endocardial mapping over the triangle of Koch or along the tendon of Todaro (31)may have yielded more information about the exact FP and SP location. However, unlike intraoperative computerized mapping (32), fluoroscopy cannot identify precise endocardial anatomy and, therefore, the presumed FP or SP location has only been inferential, even with the use of decapolar electrode catheters-an inherent limitation to clinical electrophysiologic study. In addition, mapping restricted over the right endocardial surface can only provide limited information about the excitation of the AV node and the atrial septum, which are three-dimensional subendocardial ...

Title: Mitral Balloon Valvuloplasty: State-of-the-Art Paper. VOLUME: 2 ISSUE: 1. Author(s):Mohamed E. Fawzy. Affiliation:Consultant, Adult Cardiology,King Faisal Heart Institute (MBC-16), King Faisal Specialist Hospital&Research Center, PO Box 3354, Riyadh 11211, Saudi Arabia.. Keywords:Mitral valve, mitral stenosis, valvuloplasty. Abstract: Percutaneous mitral balloon valvuloplasty (MBV) was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, MBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS). With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined. When the reported complications of MBV are viewed in aggregate, complications occur at approximately the following rates: mortality (0% to 0.5%), cerebral accident (0.5% to 1%), mitral regurgitation (MR) requiring surgery (2% to 3%). These ...

Figure 6 3D TEE to Guide Deployment and Assess Device Position. During the procedure, "live 3D" or a "3D zoom" mode is used to observe the position of guidewires, sheaths, and devices in real time (Online Video 4). Panel A depicts a 3D image of the ASD from the right atrial side demonstrating the delivery sheath being positioned through the defect. 3D echocardiography is particularly helpful in patients with multiple ASDs to ensure placement of the delivery sheath through the bigger defect. 3D echocardiography can be potentially helpful in patients with difficult ASDs by demonstrating the alignment of the discs against the septum during deployment (Online Video 5) (7). Panel B demonstrates the deployment of the LA disc which is still attached to the deployment catheter. The LA disc is fully expanded and is seen to align well against the atrial septum. Panel C demonstrates the ASD device post-deployment; the device is well aligned against the septum and both the discs are well visualized on ...

In the standard precordial echocardiographic imaging planes, there is frequent dropout of atrial septal echoes in the region of the fossa ovalis that can be minimized by use of the subcostal imaging approach. The diagnostic sensitivity of this approach was reviewed in 154 patients (mean age 31 years, range 2 months to 74 years) with documented atrial septal defect in whom a satisfactory image of the atrial septum could be obtained.. Subcostal two-dimensional echocardiography successfully visualized 93 (89%) of the 105 ostium secundum atrial septal defects, all 32 (100%) ostium primum defects and 7 (44%) of the 16 sinus venosus defects. A defect was not visualized (false negative response) in 12 patients (11%) with an ostium secundum defect and in 9 patients (56%) with a sinus venosus defect. In three of the former and five of the latter, a two-dimensional echocardiographic contrast examination established the presence of the interatrial shunt. Twenty-four patients (16%) with clinical findings of ...

Epicardial fat is true visceral fat deposited around sub epicardial coronary vessels; it has been implicated in the development of coronary atherosclerosis. Epicardial fat has been also associated with insulin resistance. Trans thoracic echocardiography provides a reliable measurement of epicardial fat thickness. Objective: To evaluate the association between epicardial fat thickness with metabolic syndrome and anthropometric parameters of adiposity. Methods: We assessed 70 patients who underwent echocardiography; the epicardial fat thickness on the free wall of the right ventricle was measured at end-diastole from the parasternal long-axis views of 3 cardiac cycles with Aloka Alfa 6 equipment (Japan), by 2 cardiologists who were unaware of the clinical data. Metabolic syndrome was defined according with the International Diabetes Federation criteria. The association between epicardial fat thicknesses with metabolic syndrome was evaluated with the fisher exact test, whereas its correlation with body
This study was designed to achieve better understanding of (1) how carboxysome genes are regulated and expressed to yield with precise relative ratios and (2) the in vivo roles of two sets of conserved bacterial microcompartment genes, namely the three csoS1 and two csoS4 genes of H. neapolitanus , in the biogenesis and function of the carboxysome. For the first goal, a detailed transcriptional profile of carboxysomal genes in H. neapolitanus was established using absolute quantification real-time RT-PCR and transcript ends analysis. This transcriptional profile revealed that a single promoter, denoted cso promoter, was located upstream from the clustered carboxysomal genes. Transcripts of all nine carboxysomal genes were detectable but were present at different levels. In vivo activities of the cso promoter and selected internal non-coding regions within the carboxysome operon were further examined by using a promoter reporter vector and by generating a cso promoter deletion mutant.

Im on atenolol which is suppose to help with it but my dosage is so low right now due to my doctors thinking its the cause of my hair loss that it isnt helping well. When I was on the 50mg it helped alot! I drink coffee - half caf - and dont notice any difference with it. Yes it can be brought on by stress and anxiety. I have a panic disorder. If youve had your heart checked out by a cardiologist which Id recommend just to be sure, and everything is ok youll feel a little better about it when it happens. It is considered normal from what my doc has told me. If its really bothersome you could ask for a beta blocker which may help but it also lowers your blood pressure and heart rate so you have to be careful with that if yours are normal. I know what youre going through and yes it can be scary at times. Get checked out by a cardio doc. I ...
This paper presents the results of a study to evaluate the efficiency of a modified vortex separator (MVS) and an ultraviolet (UV) disinfection unit for direct treatment of combined sewer overflows (CSOs). The MVS included dissolved air and coagulant addition. The effluent from the vortex separator was disinfected continuously using UV light. Bench-scale tests were performed on CSO samples to screen various coagulants and operating pressures for dissolved air. Field tests were performed at the CSO pilot facility where simulated as well as actual storm-generated overflow events were studied.. Performance comparisons between the MVS and other CSO treatment technologies are presented. Results indicate that the MVS achieves pollutant removals superior to conventional sedimentation for the same surface loading rates, or can be hydraulically loaded several times higher than sedimentation to achieve the same results. The results also indicate that the MVS significantly improved solids concentration ...

Piercing procedure must necessarily take place in a clean, safe and professional environment and only a qualified person can perform this procedure. A place where you decide for piercing should be cleaned and disinfected needle with which you puncture the desired location must be sterile and sharp. Septum piercing healing time may vary, but is usually around 2-6 weeks.. Then follows the insertion of needle which was previously sterilized. The material used must be discarded after use and disposed of in a container intended for this type of waste. A person who has performed the piercing is obliged to give all necessary instructions, namely, how should we go to the area where the septum piercing jewelery is installed and as swiftly as possible without adverse consequences. Well check out the premises, as they must be clean and adequate. Do not perform piercing on suspicious sites. Even the person who performs the piercing must take care with cleaning prior to the procedure and must wash and ...
This defect is present in every newborn baby. It is a gap in the wall between the upper two chambers of the heart, which should close soon after birth.. Whilst a baby is in the womb, oxygen is supplied by the placenta via the umbilical cord and the babys lungs are not expanded and require only a small amount of blood for them to grow. The patent foramen ovale is one of a number of natures "short circuits" which allows blood to bypass the babys lungs whilst in the womb.. Usually the ductus arteriosus (a connection between the aorta and the lung artery) and the other "short circuits" close within a few days of birth, and the connections between the two sides of the heart no longer exist. The resistance to blood flow quickly falls with the onset of breathing and the left side pressures become greater than the right, this pushes the flap of the Patent Foramen Ovale closed and in most people it seals over.. ...

Primary cardiac tumors are very uncommon. Seventy five percent of them are benign tumors and these are mostly myxomas. The malignant cardiac tumors, the majority of which are undifferentiated sarcomas, comprise up to 25% of all cardiac tumors. A primary malignant sarcoma of the myocardium is exceedingly rare. Thus, there have been very few such cases reported in the literature. We present here a case of a 15 year old man who had complaints of orthopnea and increasing exercise intolerance over a one month period. Transthoracic echocardiography demonstrated a well demarcated huge mass with left ventricular inflow obstruction on the posterior wall of the left atrium. The patients symptoms were relieved by surgery. The histological diagnosis was an unclassified spindle cell sarcoma ...
