Right heart haemodynamics after lung resection; the role of the transthoracic echo-doppler cardiography.

We analyzed 80 patients with lung resections due to lung carcinoma operated at the Clinic for Thoracic Surgery. We performed lobectomy or bilobectomy in all cases, the patients were between 50 and 70 years old and the preoperative preparing was the same. The patients were divided in 2 groups; group A -- the patients with anamnesis for myocardial infarction, arrhythmia, pulmonary hypertension or restrictive respiratory disease and group B -- patients without such a history. Echo Doppler cardiography was performed in all cases to measure the main parameters that present the heart-lung hamodynamics. We found some changes even in group B (increased RVEDV, decreased EF, increased pulmonary systolic pressure) which can be a reason for cardiac complications after this type of surgery. The echo-Doppler cardiography is a sensitive and non-invasive method to obtain all valid parameters to present heart-lung haemodynamics.

Hospital-acquired brevundimonas vesicularis septicaemia following open-heart surgery: case report and literature review.

Brevundimonas vesicularis (B. vesicularis) is a pseudomonad rarely encountered in human infection. A case of nosocomial septicaemia with this organism following open-heart surgery is presented, with a review of the literature. The isolate demonstrated resistance to ciprofloxacin and aztreonam, which has not yet been reported. Treatment with piperacillin/tazobactam resulted in full recovery. A review of the literature reveals that B. vesicularis is a virulent organism involved in serious infections such as central nervous system infection or bacteraemia, some of which are nosocomial. Meanwhile, empiric therapy for B. vesicularis infection should include a broad-spectrum antimicrobial agent until susceptibility results are known.

Perioperative complications in combined aortic valve replacement and extraanatomic ascending-descending bypass.

BACKGROUND: In adult patients, the combination of severe aortic valve stenosis and coarctation is rare. Surgical options comprise either a two-stage approach with valve replacement and subsequent repair of the coarctation or a one-stage repair involving valve replacement and insertion of an extraanatomic bypass graft from the ascending to the descending aorta. METHODS: We report the cases of 2 adult patients with this combined lesion who underwent simultaneous aortic valve replacement and transpericardial bypass of the coarctation. RESULTS: Weaning from extracorporeal circulation and restoration of spontaneous circulation required resuscitative measures. By increasing mean arterial perfusion pressure using norepinephrine, the observed hemodynamic instability could be controlled effectively. CONCLUSIONS: Changes in the hemodynamics of the thoracic vascular bed resulting in coronary malperfusion are discussed to be the major cause of heart failure and life-threatening ventricular arrhythmias seen in our patients after aortic valve replacement and insertion of an ascending-descending aorta bypass graft. Awareness of the complications described is considered important for successful management of these high-risk patients.

Late outcome of valve replacement with the Cross-Jones caged-lens prosthesis.

A 58 year old woman underwent re-replacement of a Cross-Jones caged-lens mitral prosthesis 23 years after the first operation. She represented one of the 38 patients who received 42 Cross-Jones prostheses two decades earlier. Continued adequate performance for more than two decades in five patients bears a surprising testimony to the longevity of this historic low profile prosthesis.
