Medical therapy or revascularization for patients with chronic total occlusion? A dilemma almost solved

2020

Chronic total occlusion (CTO) of the coronary arteries are relatively common, observed in approximatively 15-25% of patients with coronary artery disease undergoing coronary angiography. The right coronary artery represents the most common CTO vessel, which represents about half of the CTO cases.The CTO prevalence is much higher ( 90%) among patients with prior coronary artery bypass graft (CABG), while a CTO is found in only one tenth of patients referred for ST-elevation myocardial infarction (STEMI)

Angiographic follow-up results of a randomized study on angioplasty versus bypass surgery (GABI Trial)

1996

Although several randomized trials have been performed to compare the outcomes of percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG) in patients with multivessel disease, there is little data available on angiographic follow-up results. The present substudy of the German angioplasty versus bypass surgery investigation (GABI Trial) compares the angiographic revascularization status in these two cases 6 months after treatment. Follow-up angiograms were available in 102 CABG patients and 117 PTCA patients. Although the protocol excluded patients with total occlusion, on follow-up 6 months after treatment we found total occlusion of 94 native arterie…

Management of refractory angina: an update.

2020

Abstract Despite the use of anti-anginal drugs and/or percutaneous coronary interventions (PCI) or coronary artery bypass grafting, the proportion of patients with coronary artery disease who have daily or weekly angina ranges from 2% to 24%. Refractory angina refers to long-lasting symptoms (for >3 months) due to established reversible ischaemia, which cannot be controlled by escalating medical therapy with the use of 2nd- and 3rd-line pharmacological agents, bypass grafting, or stenting. While there is uncertain prognostic benefit, the treatment of refractory angina is important to improve the quality of life of the patients affected. This review focuses on conventional pharmacolog…

The radial artery is larger than the ulnar.

2003

The radial artery is presently widely used as a bypass graft for coronary artery reconstruction. However, the traditional opinion that the ulnar artery is the larger forearm artery has been questioned.The internal diameters of the radial and ulnar arteries were measured at the wrist in postmortem angiograms of 24 cadavers. Differences in mean values of variables between ulnar and radial arteries were analyzed using the Wilcoxon test.The mean diameter of the radial artery was 28% larger than that of the ulnar artery in the right arm (p0.001) and 26% larger in the left arm (p0.001). In the right arm the radial artery was dominant in 20 of 24 cadavers (83%), the ulnar artery in 3 of 24 (13%), …

Cirurgia coronària amb i sense circulació extracorpòria. Morbimortalitat postoperatòria i seguretat a curt i llarg terme

2016

OBJETIUS: Les malalties cardiovasculars representen el 25-40% de totes les morts a Europa i Amèrica del Nord amb una majoria causada per coronariopaties. La cirurgia de revascularització coronària amb circulació extracorpòria (CEC) segueix sent el “gold stàndard” del tractament quirúrugic d’aquesta patologia. Malgrat la millora de les tècniques i l'experiència quirúrgica, part de la morbiditat relacionada amb la cirurgia coronària és causada per la CEC i és per aquest motiu l’augment de procediments de revascularització coronària sense CEC les darreres dècades. L’ objectiu d’aquesta tesi és descriure l’experiència del nostre centre durant 20 anys (1993-2013) en la cirurgia cardiaca de revas…

Pirmreizējas sirds ritma izmaiņas pacientiem pēc atvērtās sirds operācijas

2019

Pēcoperācijas ātriju fibrilācija (POĀF) ir biežākā komplikācija pacientiem, kuriem veikta operācija uz atvērtas sirds. Kā rezultātā tā ietekmē morbiditāti, mortalitāti, kā arī palielina finansiālas izmaksas. Pētījuma mērķis ir uzzināt vai ir korelācija starp veiktiem pirms operācijas standarta izmeklējuma rezultātiem un pēcoperācijas ātriju fibrilāciju. Jo nosakot augsta riska pacientu var uzsākt preventīvu ārstēšanu. Materiāli un metodes: retrospektīvs pētījums, kur tika iekļauti pacienti, kam veikta sirds operācija ar sternotomijas pieeju, kuriem pirms operācijas bija sīnusa ritms n = 111. 39 pacienti netika iekļauti pētījumā, jo pirms operācijas bija ātriju fibrilācija vai anamnēzē ātrij…
