Prognostic Implications of the Novel Pulmonary Hypertension Definition in Patients with Aortic Stenosis after Transcatheter Valve Replacement.

J Clin Med 2022 Jul 22;11(15). Epub 2022 Jul 22.

Faculty of Medicine, Department of Medicine, Geneva University, 1206 Geneva, Switzerland.

: Pulmonary hypertension (PH), traditionally defined as a mean pulmonary artery pressure (PAP) ≥ 25 mmHg, is associated with poor outcomes in patients undergoing a transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). Recently, a novel definition for PH has been proposed, placing the cut-off value of mean PAP at 20 mmHg, and introducing pulmonary vascular resistance as an exclusive indicator for the pre-capillary involvement. In light of the novel criteria, whether PH still preserves its prognostic significance remains unknown. Read More

Successful management of a bleeding complication during transaxillary transcatheter aortic-valve implantation: a case report.

Eur Heart J Case Rep 2022 Jul 5;6(7):ytac280. Epub 2022 Jul 5.

Department of Cardiology, Heart Center, Zentralklinik Bad Berka, Robert-Koch-Allee 9, 99437 Bad Berka, Germany.

Background: The axillary artery is an alternative access route for transcatheter aortic-valve implantation (TAVI) in patients who have unfavourable femoral arteries as well as comorbidities which preclude surgery. Transaxillary TAVI (TAx-TAVI), with a complete non-transfemoral approach, is a feasible and safe alternative even if complications like vascular closure device failure with bleeding occurs.

Case Summary: We describe here a simplified non-transfemoral TAx-TAVI approach in a 71-year-old patient with pulmonary oedema due to severe symptomatic aortic stenosis with a prohibitively high surgical risk (Society of Thoracic Surgeons Mortality 11. Read More

Authors:
Hayk Ghukasyan

Cureus 2022 Jul 3;14(7):e26528. Epub 2022 Jul 3.

Internal Medicine, University of Hawaii, Honolulu, USA.

Carcinoid syndrome can cause desmoplastic reactions to nearby tissues. When it involves the heart, it causes carcinoid heart disease (CHD) or Hedinger syndrome and usually involves the right-sided heart valves, causing tricuspid insufficiency and pulmonary stenosis (TIPS) and eventually leading to right-sided heart failure. The management of patients with CHD is complex, as both the systemic malignant disease and the heart involvement have to be addressed. Read More
