Abstract

Chronic atrial stretch and rheumatic inflammatory activity leads to atrial dilatation, conduction slowing, and this increases the susceptibility to atrial fibrillation (AF). The aim of this study was to examine the effects of changes in the chronic atrial stretch on atrial refractoriness in early period after percutaneous mitral balloon commissurotomy (PMBC) in patients with mitral stenosis and sinus rhythm. We evaluated the changes in pulmonary arterial pressure (PAP), left atrial (LA) pressure, right atrial (RA) pressure, mean mitral diastolic gradient and mitral valve area beside changes in atrial effective refractory periods (AERPs), AERP dispersion, intra- and interatrial conduction times after PBMC in 25 patients. The following hemodynamic parameters were decreased after PBMV mean diastolic gradient (14.5 ±2.6 - 2.8 1.3 mmHg, p

Özet

Kronik atriyal gerilme ve romatizmal enflamatuvar aktivite, atriyal dilatasyon ve kardiyak iletimde yavaşlamaya bağlı olarak atriyal fibrilasyona (AF) duyarlılığı artırır. Bu çalışmanın amacı, mitral darlığı olan sinüs ritmindeki hastalarda perkutan mitral balon valvüloplasti (PMBV) sonrası erken dönemde kronik atriyal gerilmedeki değişikliğin atriyal refrakterlik üzerindeki etkilerini araştırmaktır. Çalışmaya alman 25 hastada PMBV sonrası atriyal effektif refrakter periodlar (AERP), AERP dispersiyonu ve interatriyal ileti zamanlarının yanı sıra pulmoner arter basıncı (PAB), sol atriyal (LA) basınç, sağ atriyal (RA) basınç, ortalama mitral diyastolik gradiyent ve mitral kapak alanındaki değişimler değerlendirilmiştir. PBMC sonrası ortalama diyastolik gradiyent (14.5 ±2.6 - 2.8 ±1.3 mmHg, p< 0.001), PAB (53.1 ±12.6 - 35.7+8.9 mmHg, p< 0.001), ortalama RA (6.2 ±1.0 - 4.9 ±0.4, p=0.03), ve LA basınçlarında (25.7 ±4.3 -12.5 ±2.6 mmHg, p< 0.001), ve LA çapında (6.2 ±1.0 - 4.9 ±0.4, p-0.03) belirgin azalma görülmüştür. Yüksek sağ atriyum (HRA), distal koroner sinüs (DCS), sağposterolateral (RPL) AERP'lerde artma (216.1 ±15.0- 251.1 ±17.1; 226.7 ±17.5 - 269.5 ±24.8, 207.6 ±20.4 - 259.2 ±20.7 msn) (p< 0.001) ve AERP dispersiyonu (55.2 ±5.5 - 21.5 ±4.7 msn, p
