ABSTRACT
Intravascular lithotripsy can be used as an effective therapy for lesion preparation in severely calcified lesions. The mechanism, as shown by optical coherence tomography, is calcium fractures. The aforementioned modification is performed with minimal risk of perforation, no-reflow and a low incidence of flow-limiting dissection and myocardial infarctions. Other techniques, such as cutting or scoring balloons and rotational atherectomy have also been shown to increase luminal diameter, but other complications, such as distal embolization, induced by these treatment modalities, are a source of concern. This review describes a single-center study of all-comer patients, including those with complex characteristics. This therapy is very effective, with a very low risk of complications. In this article, we characterize the mechanism of action of the intravascular lithotripsy catheter, its optical coherence tomography validation, clinical applications, and comparison with other calcium-modifying technologies, as well as future directions, which can be used to improve the technology.
ABSTRACT
Vários fatores, incluindo intervenções terapêuticas aprimoradas e tecnologias avançadas, levaram a melhores desfechos clínicos nas intervenções coronárias percutâneas complexas. No entanto, ainda podem ocorrer complicações capazes de impactar negativamente na sobrevida do paciente e nos custos de saúde. O risco dessas complicações pode ser reduzido, por meio de operadores experientes e procedimentos preventivos. Este artigo discute uma série de casos de cinco pacientes com problemas específicos relacionados aos procedimentos, como perfuração coronária, dissecções, fechamento abrupto das coronárias e fenômeno de no-reflow.
Various factors, including improved therapeutic interventions and advanced technologies, have led to better clinical outcomes for complex percutaneous coronary interventions. However, complications can still occur and have a negative impact on patient survival and healthcare costs. The risk of these complications can be reduced through experienced operators and preventative procedures. This article discusses a case series of five patients with specific periprocedural issues, such as coronary perforation, dissections, abrupt closure of the coronaries, and no-reflow phenomenon.
