Severe and Apparently Irreversible Pulmonary Arterial Hypertension in a Patient with Ostium Secundum Atrial Septal Defect - A Successful Case of Treat and Close Strategy.

Irreversible pulmonary arterial hypertension is considered a contraindication for surgical or percutaneous closure of atrial septal defects (ASD) due to risk of right heart failure. We present a case of 37 years-old woman who was referred to our center due to progressive worsening fatigue and high probability of pulmonary hypertension on a transthoracic echocardiogram. The diagnostic work-up revealed the presence of an ostium secundum atrial septal defect and severe pre-capillary pulmonary hypertension on right heart cathetherization (RHC).

Continuous Aspiration Mechanical Thrombectomy for the management of intermediate- and high-risk pulmonary embolism: Data from the first cohort in Portugal.

Introduction: This study describes the experience of a reference center using continuous aspiration mechanical thrombectomy for acute high- and intermediate-high-risk pulmonary embolism (PE).

Methods: Twenty-nine consecutive patients with acute central PE (48.3% high-risk PE; 82.

Safety and efficacy of balloon pulmonary angioplasty in a Portuguese pulmonary hypertension expert center.

Introduction: Balloon pulmonary angioplasty (BPA) is an alternative therapy in patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) or residual/recurrent pulmonary hypertension (PH) after surgery. The aim of this study was to assess the short-term efficacy and safety of a BPA program.

Methods: This prospective single-center study included all BPA sessions performed in CTEPH patients between 2017 and 2019.

Chronic thromboembolic pulmonary hypertension secondary to implantable cardioverter defibrillator lead thrombus in a patient with Brugada syndrome: a rare complication requiring a multidisciplinary approach.

We report the case of a 57-year-old male patient with prior syncope associated with sustained ventricular tachycardia in the setting of Brugada syndrome, who was submitted to implantation of a cardioverter defibrillator for secondary prevention. During follow-up, he presented a significant increase in lead impedance, and a transthoracic echocardiogram showed a mass attached to the lead. He was started on oral anticoagulation after infective endocarditis was excluded but nevertheless suffered repeated episodes of pulmonary embolism that led to severe chronic thromboembolic pulmonary hypertension.

Dyspnea in antiphospholipid syndrome: Beyond pulmonary embolism.

Pulmonary embolism due to primary antiphospholipid syndrome is rarely associated with chronic thromboembolic pulmonary hypertension, and therefore according to the latest guidelines on pulmonary hypertension, routine screening is not recommended. We describe a young patient with a late diagnosis of chronic thromboembolic pulmonary hypertension in the context of pulmonary embolism, primary antiphospholipid syndrome and suboptimal anticoagulation. Of note, mild cardiopulmonary symptoms were consistently misattributed to a depressive disorder because physical examination was normal, serial Doppler echocardiography failed to show pulmonary hypertension, and all other diagnostic tests were normal.

Echocardiographic assessment of right ventricular contractile reserve in patients with pulmonary hypertension.

Introduction And Aim: Right ventricular function is a major determinant of prognosis in pulmonary hypertension. The aim of this study was to assess and compare right ventricular contractile reserve in healthy subjects (controls) and in subjects with pulmonary hypertension (cases).

Methods: In this prospective study of seven cases and seven controls undergoing treadmill stress echocardiography, right ventricular S-wave velocity, tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RVFAC) and stroke volume index were assessed at rest and with exercise.
