Introduction: The clinical significance of left atrial (LA) involvement and dysfunction in ATTR amyloidosis cardiomyopathy (ATTR-CM) has not been characterized. We sought to study: 1) LA pathology in heart specimens from ATTR-CM patients 2) LA stiffness and mechanics using echocardiographic speckle tracking (EST) in cardiac ATTR-CM 3) the association between parameters of atrial function and mortality. Methods: Congo red staining and immunohistochemistry was performed to assess amyloid in the atria from 5 ATTR-CM heart specimens. 2D EST was used to assess LA reservoir, conduit, contractile function and stiffness in 906 ATTR-CM patients (551 wt ATTR; 93 T60A ATTR; 241 V122I ATTR; and 21 other gene variants). Results: There was extensive ATTR amyloid infiltration in the 5 atria, with loss of normal architecture, infiltration and remodelling of vessels, capillary disruption and subendocardial fibrosis. EST demonstrated increased atrial stiffness [median (25th-75th quartile) 1.83 (1.15-2.92)] that remained independently associated with reduced survival, after adjusting for known prognostic variables (lnLA stiff: HR= 1.26, CI 1.07-1.57; p=.009). There was substantial impairment of the three phasic functional atrial components [reservoir 8.86(5.94-12.97)%; conduit 6.5(4.53-9.28)%; and contraction 4.0(2.29-6.56)%]. Atrial contractile function was absent in 21.6% of patients whose ECG showed sinus rhythm (SR)-atrial electro-mechanical dissociation (AEMD). AEMD was associated with a poorer prognosis compared to SR patients who had effective mechanical contraction (p <.0001). AEMD conferred a similar prognosis to patients in AF. Conclusions: The phenotype of ATTR-CM includes clinically significant infiltration of the atrial walls characterized by progressive loss of function and increased stiffness, a strong independent predictor of mortality. AEMD emerged as a distinctive functional phenotype identifying patients in SR with poor prognosis.

Primary Cardiac Tumors

Primary cardiac tumors are rare and approximately half of them are atrial myxomas. They rarely remain asymptomatic, especially if large. The imaging of a myxoma by contrast dye during coronary angiography is an infrequent sign, which clarifies the vascular supply of the tumor. We report herein an interesting and rare case of a left atrial myxoma hypervascularized from the right coronary artery.

Pericardial Cavity

Contrary to what the name implies, the left atrial appendage is increasingly becoming an organ of clinical importance. Its role in the pathogenesis of thromboembolism is now well established. Enlargement of the appendage due to haemodynamic disturbances or anatomic weakness increases this risk, along with the potential for arrhythmia. We report a rare case of gross enlargement of the left atrial appendage within the pericardial cavity.

Life Threatening

Cardiac tumors are generally benign. But its danger lies not in its potential malignancy, but in its location. These tumors settle inside the cardiac cavities, at the origin or mouth of the great vessels or even on the valves. This can obviously lead to life-threatening complications, either due to mechanical causes or disturbances in the electrical conduction of the heart.

Advances in imaging have resulted in more frequent reporting of primitive right atrial structures which can sometimes mimic cardiac tumors in prenatal ultrasound. Prominent crista terminalis and Chiari network are examples of these structures. We describe two cases of pregnant women referred to the fetal cardiology clinic for fetal echocardiography for right atrial masses seen on prenatal ultrasound suspicious of tuberous sclerosis. The first case subsequently diagnosed as crista terminalis and the second case as a prominent Chiari network. Postnatal ECHO confirmed the benign nature of these structures. It is important to differentiate tumors from prominent benign structures in the right atrium in fetal ECHO. The location and the similar echogenicity to the adjacent atrial tissue are clues for differentiation of these structures from atrial tumors.

Atrial Myxoma is the most common primary cardiac tumors accounting for about 50% of benign primary cardiac tumors, with the majority located in the left atrium. This is a case of large left atrial (LA) myxoma presented with features of mitral stenosis associated with moderate left ventricular failure (LVF) and mild pulmonary artery hypertension (PAH) The patient improved markedly after tumor excision.Pulse Vol.10 January-December 2017 p.29-33

Cardiac Masses

A tumor is an excessive growth of cells that results from the body’s inability to balance the growth of new cells and the destruction of old cells. Tumors can occur throughout the body and are classified as either benign or malignant. However, cardiac tumors are a rare occurrence. When present, several imaging modalities are available to illustrate their presence and characteristics. Not all cardiac masses look similar and, depending on their size and location, may pose different health risks to the patient. This case series introduces six left atrial myxomas with dissimilar appearances initially detected by transthoracic echocardiography, along with cross-correlation by transesophageal echocardiography, computed tomography, and mechanical resonance imaging.
