BACKGROUND: Balloon aortic valvuloplasty (BAV) is a percutaneous treatment option for severe, symptomatic aortic stenosis. Due to early restenosis and failure to improve long term survival, BAV is considered a palliative measure in patients who are not suitable for open heart surgery due to increased perioperative risk. BAV can be used also as a bridge to surgical or transcatheter aortic valve implantation (TAVI) in haemodinamically unstable patients or in patients who require urgent major non-cardiac surgery. PATIENTS AND METHODS: We reported on 6 oncologic patients with severe aortic stenosis that required a major abdominal and gynaecological surgery. In 5 cases we performed BAV procedure alone; in one patient with concomitant coronary artery disease we combined BAV and percutaneous coronary intervention (PCI). RESULTS: With angioplasty and BAV we achieved a good coronary artery flow and an increase in aortic valve area without any periprocedural complications. After the successful procedure, we observed a hemodynamic and symptomatic improvement. As a consequence the operative risk for non-cardiac surgery decreased and the surgical treatment of cancer was done without complications in all the 6 cases. CONCLUSIONS: BAV can be utilized as a part of a complex therapy in severe aortic stenosis aimed to improve the quality of life, decrease the surgical risk for major non-cardiac surgery or as a bridge to surgical or transcatheter aortic valve implantation.
RESUMO
Sirolimus is a well-known, potent immunosuppressant that is widely used in solid-organ transplantation, but it is not without potential side effects. A rare but devastating adverse effect is sirolimus-associated pulmonary toxicity. We report a case of sirolimus-induced diffuse alveolar hemorrhage confirmed by bronchoscopic findings (after other possible etiologies were ruled out) and by clinical and radiographic resolution of the pulmonary signs and symptoms a few days after sirolimus administration was stopped. This case and the existing literature on this topic suggest that sirolimus-induced pulmonary toxicity should be suspected in any patient taking immunosuppressants and who develops unexplained pulmonary symptoms.
