Pulmonary endarterectomy in chronic thromboembolic pulmonary hypertension: Relationship between treated branches and outcome.

Background: In patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing pulmonary endarterectomy (PEA) it is important to minimize residual obstructions, in order to achieve low postoperative pulmonary vascular resistances and better clinical results. The aim of the study was to test the hypothesis that the greater the number of pulmonary artery branches treated at surgery, the better the hemodynamic and clinical outcome after PEA.

Methods: In 564 consecutive CTEPH patients undergoing PEA the count of the number of treated branches was performed directly on the surgical specimens.

Risk stratification in patients with residual pulmonary hypertension after pulmonary endarterectomy.

Background: Few studies addressed the issue of risk stratification in patients with residual pulmonary hypertension (PH) after pulmonary endarterectomy (PEA). This study tested the potential added value of parameters that have not been included in existing risk models.

Methods: We evaluated 546 consecutive patients with chronic thromboembolic pulmonary hypertension who underwent PEA and were followed-up for a median period of 58 months.

Radiological differences between chronic thromboembolic pulmonary disease (CTEPD) and chronic thromboembolic pulmonary hypertension (CTEPH).

Objectives: The aim of this study was to describe the radiological features of chronic thromboembolic pulmonary disease (CTEPD), not yet systematically described in the literature. Furthermore, we compared vascular scores between CTEPD and chronic thromboembolic pulmonary hypertension (CTEPH) patients, trying to explain why pulmonary hypertension does not develop at rest in CTEPD patients.

Methods: Eighty-five patients (40 CTEPD, 45 CTEPH) referred to our centre for pulmonary endarterectomy underwent dual-energy computed tomography pulmonary angiography (DE-CTPA) with iodine perfusion maps; other 6 CTEPD patients underwent single-source CTPA.

Pulmonary endarterectomy in the octogenarian population: safety and outcomes.

Aims: Aim of the study was to verify the feasibility, safety and efficacy of pulmonary endarterectomy (PEA) in octogenarian patients with chronic thromboembolic pulmonary hypertension.

Methods: We retrospectively analyzed 635 chronic thromboembolic pulmonary hypertension patients who underwent PEA at our center and were followed-up for at least 1 year. The end-points of the study were in-hospital mortality, hemodynamic results at 1 year and long-term survival.

Surgical Treatment for Pulmonary Embolization of a Right Atrial Myxoma.

We report the case of a woman with pulmonary embolism due to a cardiac mass. Echocardiography, computed tomography scan, and cardiac magnetic resonance raised the suspicion of right atrial myxoma and confirmed the presence of pulmonary embolism. The patient was sent to the University of Pavia School of Medicine, where the atrial myxoma was excised, and, using interrupted periods of circulatory arrest, extraction of the myxoma emboli from the pulmonary arteries was performed.

Minimally invasive heart-port assisted technique as standard first choice approach for left ventricle endoplasty: a ten-year single-center experience.

Background: Although the port-access technique has been shown to be an effective and safe approach for cardiac surgery procedures it has never become routine practice, and it is still limited to few and selected centers. Furthermore, such technique has rarely been applied to treat left ventricle disease. In 1999 we introduced left ventricle aneurysm repair through a left minithoracotomy using the port-access technique.

The axillary artery as an alternative site of cannulation for redo port access-assisted minimally invasive mitral valve surgery: early report of 2 cases.

The minimally invasive Heartport (HP)-assisted technique has become first choice option for mitral valve surgery in many centres.The pool of patients potentially treated using HP techniques, however, is still limited by the presence of peripheral vessel disease, expecially in the elderly population. Alternative approaches to using the HP technique safely in such a subset of patients, therefore, should be evaluated.

Should we perform heart retransplantation in early graft failure?

Cardiac retransplantation represents the gold standard treatment for a failing cardiac graft but the decision to offer the patient a second chance is often made difficult by both lack of donors and the ethical issues involved. The aim of this study was to evaluate whether retransplantation is a reasonable option in case of early graft failure. Between November 1985 and June 2008, 922 patients underwent cardiac transplantation at our Institution.

Long-term outcome after pulmonary endarterectomy.

Rationale: There are few follow-up studies on long-term cardiopulmonary function after pulmonary endarterectomy (PEA), the operation of choice for chronic thromboembolic pulmonary hypertension (CTEPH).

Objectives: To prospectively evaluate long-term outcome of patients with CTEPH treated with PEA.

Methods: Between 1994 and 2006, 157 patients (mean age 55 yr) were treated with PEA at Pavia University Hospital.

[Surgical treatment of chronic thromboembolic pulmonary hypertension with pulmonary endarterectomy].

Acute pulmonary embolism is the third most common cardiovascular disease in Italy with approximately 65 000 new cases a year. Appropriate medical therapy does not necessarily prevent evolution of acute pulmonary embolism into chronic thromboembolic pulmonary hypertension (CTEPH), which occurs in 0.1-4.
