Pulmonary agenesis: Importance of the diagnosis

Characteristics of coronary microcirculatory function in patients with Takotsubo syndrome.
2017
Background: Takotsubo syndrome (TS) is a recently described cardiac syndrome whose pathogenesis is still unclear. We investigated the characteristics of coronary microcirculatory function in patients with TS through the analysis of the TIMI frame count (TFC) compared to normal subjects and with to subjects with microvascular angina (MA). Methods: We enrolled 71 TS patients (F:M =69:2, mean age of 65.27±9.53 years), 70 controls (F:M =34:36, mean age of 56.63±13.5 years) and 71 patients with MA, (F:M =69:2, mean age of 65.9±9.2 years). The assessment of the microcirculation was carried out through the TFC. Results: microcirculation was significantly altered in patients with TS compared with h…
Extracorporeal circulation and cardiac arrest in an awake patient: a safe approach for single lung pulmonary artery stenting?
2005
We describe the anesthetic concept and approach in a single lung patient scheduled for pulmonary artery stenting due to recurrence of a pulmonary artery sarcoma after left pneumectomy.
Successful surgery of neuroendocrine carcinoma infiltrating right ventricle and pulmonary artery.
2020
We present the clinical case of a 60-year-old woman complained of dyspnea on exertion. Echocardiogram showed a giant mass in the right ventricle (RV) with obstruction to the outflow tract. Thorax computed tomography confirmed a mass of greater than 60 mm infiltrating RV and causing severe stenosis in the pulmonary artery, with severe pericardial effusion. Cardiac surgery was performed for tumor resection and pulmonary root replacement with a biological valved conduit. Histological analysis diagnosed a poorly differentiated large-cell neuroendocrine carcinoma. The patient had no immediate postoperative complications and has completed radiotherapy at a 9-month follow-up.
Pulmonary endarterectomy in chronic thromboembolic pulmonary hypertension.
2018
Management and outcome of patients with operable chronic thromboembolic pulmonary hypertension (CTEPH) who underwent pulmonary endarterectomy (PEA) at a large German referral center were investigated.In Germany, 394 PEAs were performed in 2014 and 2015 with an in-hospital mortality rate of 5.8%. Of these, 253 patients (64.2%) were treated at the Kerckhoff Clinic, Bad Nauheim, and 237 (93.7%; median age, 62 years [interquartile range [IQR], 52-72 years]; 46.0% female) were included in the present analysis.On referral, 52 patients (22.0%) were treated with pulmonary arterial hypertension-specific drugs and 95 (40.4%) were treated with non-vitamin K-dependent oral anticoagulants, and 14 (5.9%)…
Endovascular treatment of acute bleeding complications in traumatic aortic rupture and aortobronchial fistula.
2001
Objective: Herein we report our experience in placement of endovascular stentgrafts in the descending aorta in patients with acute bleeding complications due to traumatic rupture or aortobronchial fistula. Methods: Six patients (one woman, five men, mean age 47 ^ 19 years) were treated from September 1995 to February 2000 by implantation of endovascular stentgrafts in the descending aorta. Indications included traumatic ruptures of the aortic isthmus (na 3) and aortobronchial fistulas (na 3). All procedures were performed under general anaesthesia. The implants were introduced under fluoroscopic guidance via the aorta (na 1), the iliac (na 4) or femoral (na 2) artery, respectively. Results:…

Reoperation and the centrifugal pump?
1992
Postperfusion syndrome is still a problem in long cardiac operations using extracorporeal circulation (ECC). To evaluate whether or not centrifugal blood pumping during open heart surgery is beneficial, a randomized, prospective study was undertaken of 50 consecutive patients undergoing elective coronary artery bypass grafting. The patients were divided into two groups of 25 each. In group 1 a centrifugal pump (Biomedicus) was used as arterial blood pump, while in group 2 a roller pump (Stockert) was used. The two groups did not differ significantly and the number of variables during surgery was kept low (identical perfusion set, two surgeons, minimal cardiotomy suction). The parameters stu…
Exercise ECG Testing and Stress Cardiac Magnetic Resonance for Risk Prediction in Patients With Chronic Coronary Syndrome
2021
Vasodilator stress cardiac magnetic resonance (VS-CMR) has become crucial in the workup of patients with known or suspected chronic coronary syndrome (CCS). Whether traditional exercise ECG testing (ExECG) contributes prognostic information beyond VS-CMR is unclear.We retrospectively included 288 patients with known or suspected CCS who had undergone ExECG and subsequent VS-CMR in our institution. Clinical, ExECG, and VS-CMR variables were recorded. We defined the serious adverse events (SAE) as a combined endpoint of acute coronary syndrome, admission for heart failure, or all-cause death.During a mean follow-up of 4.2 ± 2.15 yr, we registered 27 SAE (15 admissions for acute coronary syndr…
