Coronary Artery-to-Pulmonary Artery Collaterals in Chronic Thromboembolic Pulmonary Hypertension

Coronary artery-to-pulmonary artery collaterals in chronic thromboembolic pulmonary hypertension.

Pulmonary artery dysfunction in chronic thromboembolic pulmonary hypertension

Background Unresolved thromboemboli in the pulmonary arteries (PA) is known to cause chronic thromboembolic pulmonary hypertension (CTEPH). However, it remains unknown if vascular dysfunction in pulmonary arteries exists in patients with CTEPH. Methods and results We enrolled 7 female patients with CTEPH in this study, who have stable pulmonary hemodynamics after balloon pulmonary angioplasty...

Drug Therapy in Patients with Chronic Thromboembolic Pulmonary Hypertension

Background: Chronic Thromboembolic Pulmonary Hypertension (CTEPH) results from the obstruction of predominantly major pulmonary vessels by organized blood clots and is one of the causes of pulmonary hypertension. The disease is still underdiagnosed and the true prevalence is not clear. The objective of this study was to determine the clinical characteristics and current management of patients w...

Severe Compression of the Left Main Coronary Artery in a Patient with Chronic Thromboembolic Pulmonary Hypertension.

Extrinsic compression of the left main coronary artery (LMCA) can occur in patients with an enlarged pulmonary artery trunk secondary to severe pulmonary hypertension (PH). This phenomenon rarely occurs in PH; moreover, few reports have shown that chronic thromboembolic PH can be a triggering factor for this syndrome. Herein, we describe a patient with extrinsic compression of the LMCA with chr...

Pulmonary hypertension secondary to coronary-to-pulmonary artery fistula.

The coronary fistula is an anomaly characterized by the communication between a coronary artery and a cardiac chamber, pulmonary artery, coronary sinus and pulmonary veins. It represents 0.2 to 0.4% of the congenital cardiopathies and 0.1% to 0.2% of the adult population submitted to coronary angiography. We report the clinical case of a 64-year-old female patient, whose anomaly was diagnosed d...
