Intracardiac masses: Single center experience within 12 years: I-MASS Study

A Right Ventricular Mass With Intracavitary Obliteration: Tumor or Thrombus?

A 47-year-old woman was admitted to the hospital because of dyspnea for the past three months. She was previously diagnosed with pulmonary embolism. She had been operated on for a colon tumor five years ago and no residual cancer was detected on oncological follow-up. Her transthoracic echocardiographic and transesophageal echocardiographic evaluation showed a hypertrophic right ventricle occupied by a 2.7 x 4.8 cm immobile mass obliterated to the right ventricle cavity. All the non-invasive tests were consistent with thrombus prediagnosis. She underwent surgery. Mass was resected from the right ventricle as much as possible. Histopathology of surgical material revealed metastatic spindle cell adenocarcinoma. We aim to increase the awareness of the differential diagnosis of thrombus or tumor, thereby leading to appropriate management.

Management of a Right Heart Intracavitary Thrombus in Transit in a Patient With Gastric Cancer in a Resource-Limited Setting: A Case Report

A right atrial thrombus is an unusual source of imminent massive saddle pulmonary embolism (PE) . A hypercoagulable state secondary to gastric cancer (GC) can result in deep vein thrombosis (DVT) with a resultant right-sided heart thrombus in transit. Here, we present a case of a young male patient from Honduras with DVT and multiple venous thrombi extending from the external iliac veins to the suprahepatic left vein, inferior vena cava, and right atrium of the heart, secondary to a hypercoagulable state from GC, adenocarcinoma type. We describe the approach of treating a right heart intracavitary thrombus with imminent risk for saddle PE and sudden cardiac death with thrombolysis through a central venous catheter (CVC) in a resource-limited setting.

Multiple Intracardiac Masses Involving 3 Chambers of the Heart

•

A 42-year-old man presented with multiple cardiac masses.

•

Metastatic disease is far more prevalent than primary cardiac tumors.

•

Multimodality imaging aids in the diagnostic and management strategy.

•

Optimal treatment of large, chronic intracardiac thrombi needs to be refined.
