What is atrial dilatation

Problems in the cardiological sphere are among the most life-threatening, although this is far from all violations of the heart. Sometimes it is possible to live with vice, and a harmless arrhythmia can become a forerunner of serious pathology. Therefore, it is imperative to strictly monitor the state of the "main organ", and each diagnosis, even if it is not confirmed, should be thoroughly studied. In particular, dilatation of the atria and ventricles, which is known far less than other diseases.

Atrial Dilatation - What is it?

The word "dilation" means "expansion" or "stretching", and in relation to cardiac pathology it is used in the original sense. Dilatation of the heart implies an increase in the volume of its chambers due to the expanding walls, while their thickness does not change. This disease can not be independent - it is either a pathology, laid at the stage of fetal development, or acquired under the pressure of external / internal factors.

Should dilation be treated, and is such a disorder dangerous?

  • Firstly, it is worth noting that a person is far from always aware of this diagnosis: he has practically no particular symptoms, and possible interruptions are heart failure, arrhythmia, etc. - often associated with other cardiological problems. The diagnosis of atrial dilatation is established after an examination, and, far from always directed specifically at its detection.
  • Secondly, if the pathology is congenital, it does not lend itself to any therapy, and the only thing that can be done in such a situation is to prevent the heart from being overloaded so that, as a result of dilatation, something more serious and leading to a tragic outcome will develop.

As for the acquired dilatation, first of all it is required to determine the cause of its occurrence and to deal with its elimination.

As for the acquired dilatation, first of all it is required to determine the cause of its occurrence and to deal with its elimination: there is no sense in treating the dilatation itself. Returning the volume of the cavity to normal is possible with the elimination of the factors that determine these values. However, this does not apply to cases of chronic dilatation, in which not only the volume, but also the wall thickness, and fibrous deformity of the tissues changes. Such a process is called dilated hypertrophy and almost always needs surgical intervention. Depending on whether it is possible to remove the premise during the operation, the issue of heart transplantation is decided.

Causes of dilatation of the heart

As to the specific factors influencing the emergence and development of this disease

As to the specific factors influencing the emergence and development of this disease, it is first necessary to clarify which atrium differs from the norm in its indicators.


  • Dilatation of the left atrium usually becomes a consequence of prolonged hypertension of the great circle, generated by high physical exertion, to which the body was not adapted, i.e. testifies to the exhaustion of the resources of the heart. Accelerate the process can severe stress, as well as prolonged atrial fibrillation and flutter.
  • Dilatation of the right atrium is often triggered by small circle hypertension and is directly related to the state of the broncho-pulmonary system. It can be preceded by diseases in the chronic stage, which lead to frequent bronchial spasms (in particular, asthma), as well as pulmonary hypertension. Doctors say that infectious heart disease, heart disease or myocardial pathology can also be a cause.

It should be noted that dilatation can be established not only in relation to the atria, but also in relation to the ventricles: here the causes are stenosis and / or any myocardial pathologies.

taking into account the difference in the causes for each of the diagnoses, the method of their elimination and the very possibility of very different

Taking into account the difference in the reasons for each of the diagnoses, the method of their elimination and the possibility itself vary greatly. Dilatation of the left atrial cavity is often perceived by specialists as a disturbance that does not require anxiety, which is close to the situational nature: doctors recommend adjusting the mode of work and rest, reduce the degree of physical exertion and create the most relaxed and comfortable environment. In such a situation, the volume of the cavity often returns to its normal state independently if external factors are “turned off”.

With dilatation of the right atrium, everything is much more difficult, although some of the medical recommendations remain the same - to avoid overloading, especially in the presence of heart disease, but to strengthen the muscle and improve overall endurance. In addition, the elimination of alcohol from the diet is required (not allowed in any quantities). It will take at least half a year to adhere to the course prescribed by the doctor, and this is only if the prerequisites are not serious. If we are talking about chronic bronchial diseases, then you may need a longer therapy.

Summarizing the above, it can be argued that atrial dilatation can be both an easily solvable problem, and severe pathology flowing into dilated cardiomyopathy, thromboembolism and death. For this reason, it is highly recommended that if any symptoms of cardiac irregularities occur, it is necessary to undergo a check - both a cardiogram and an ultrasound diagnosis in order to determine their causes in time and prevent the development of a possible pathology.
