Kan thinlung ṭhian: Circumflex Artery chungchang chiang takin i zir ang u!

Kan thinlung hian mak tak maiin hna a thawk tih i ngaihtuah ngai em? Chu thinlung te tak te chhungah chuan thisen kalna kawng pawimawh tak a awm a. Chu network-a ṭhian bik pakhat chu `Circumflex Artery` tih a ni. I doctor chuan `LCx` artery, emaw `the circ` emaw a ti thei bawk. Chuvangin, vawiin hian he `Circumflex Artery` chungchang hi chipchiar zawkin kan sawi dawn em ni?

`Circumflex Artery` tih hi eng nge ni? A awlsam zawngin i hrethiam ang u!

Okay, hetiang hian han ngaihtuah teh. Kan thinlunga thisen pe chhuaktu thisen kalna kawng lian pahnih a awm a. Anni hi veilam leh dinglam coronary arteries te an ni . Chumi hnuah chuan veilam main coronary artery (the Left Main Coronary Artery) chu branch tenau zawk pahnih ah a inthen a. Chutiang branch pakhat chu kan sawi tum circumflex artery hi a ni. Branch dang chu left anterior descending artery (LAD Artery) a ni. Doctor-te chuan hei hi thisen kalna kawng bifurcation an ti a.

Chuvangin, he `(Circumflex Artery)` hnathawh ber chu oxygenated, thisen thianghlim tak chu thinlung veilam a pumping chamber hnung leh sir lama phurh hi a ni. Tui pump-a tui phur pipe ang mai a ni.

He `Circumflex Artery` hi eng nge thleng tak tak?

Kan taksa pumpuiah thisen phurtu system kan nei a, chu chu Circulatory System kan ti a ni. He ``Circumflex Artery`` hi chu system chhunga thinlung nena inzawm thisen kalna kawng pawimawh tak a ni.

Heta thil thleng hi mi tinte taksa insiam dan azirin a inang lo deuh thei . Mahse, mi zawng zawngah chuan a hnuaia thinlung veilam hmunte hi ``Circumflex Artery`` hmangin oxygen tamna thisen a pe chhuak a ni:

• Left Atrium – Hei hi thinlung veilam chamber chunglam a ni.
• Left Ventricle – Hei hi thinlung veilam hnuai lam a chamber lian tak a ni.
• Left ventricle chhunga papillary muscle awmte.

Mi thenkhatah chuan, mahse a zawng zawngah erawh chuan he `(Circumflex Artery)` hian thinlung hmun pawimawh dangah thisen a pe chhuak thin. Chu chu `Sinoatrial Node` (`SA Node`) a ni. Mi tam zawkah chuan he hna hi dinglam main coronary artery hmanga thawk a ni. He `(SA Node)` hi thinlunga electrical conduction system-a tel a ni a, chu chuan kan heartbeat a control a ni. Doctor te pawhin thinlung ``natural pacemaker`` an ti bawk.

Chuti a nih chuan khawiah nge he `Circumflex Artery` hi a awm?

Kan thinlung veilam main coronary artery chu peng hnih ah a inthen tih kan sawi tawh a. Hetah hian he `(Circumflex Artery)` hi a intan a ni. Thinlung venhimna pawn lam layer `(Epicardium) an tih chhungah a awm a ni.` A dik tak chuan thinlung veilam sir lama chamber pahnih inkar canal te tak te hmangin a kal a ni.

`Circumflex Artery` hian branch dang a nei em?

Ni e, he `(Circumflex Artery)` hian branch te zawk a chhuah bawk. Chungte chu `Marginal Artery Branches` an ti a. Heng branch awm zat hi mi zawng zawng tan a inang vek lo. Mi thenkhat chuan `Obtuse Marginal Branches` tih chu a sir lam pan tur branch pathum chauh an nei thei. Heng hnah te te hi `Left Ventricle` pawn lam, a `Apex` lam pan chuan an kal tlangpui.

Mi tlemteah chuan he `(Circumflex Artery)` hian branch dang a nei a, chu chu `Left Posterior Ventricular – LPV Artery` tih a ni. Mahse, mi tam zawkah chuan he `(LPV Artery)` (`Posterolateral Artery` tia koh bawk) hian dinglam main coronary artery atang hian branch dang `(Circumflex Artery)` an ti a.

Coronary Arterial Dominance hi eng nge ni?

Hei hi thupui thuk deuh a ni a, mahse awlsam taka hriatthiam tum ila. Kan thinlunga middle muscle layer (`Myocardium`)-a thisen pe chhuaktu artery lian ber chu `Posterior Descending Artery` (`PDA`) a ni. Chuvangin, i coronary artery priority chu eng main artery branch nge i thinlunga he `(PDA)` ah hian thisen supply tih atanga teh a ni.

Hei hi kawng pawimawh pathum hmangin a thleng thei a ni:

• Right-dominant circulation: Hei hi mi tam zawk (100 zinga 85 vel) neih chu a ni. Hetah hian PDA hian coronary artery dinglam atanga thisen a dawng thin.
• Left-dominant circulation: Hei hi mi 10 zinga 1 vel ah a awm thin. Hetah hian PDA hi Circumflex Artery emaw LAD Artery emaw atanga thisen pek a ni.
• Codominant circulation: He natna hi mi 10 zinga 2 vel ah a awm thin. PDA hian thisen hi dinglam coronary artery leh veilam circumflex artery emaw LAD artery atanga thisen a dawng vek a ni.

In pakhata tui pe chhuaktu tui pipe lian ber angin han ngaihtuah teh. In thenkhat chuan dinglam pipe atang chauh tui an hmu a, thenkhat chuan veilam atanga tui an hmu a, thenkhat chuan a sir lehlamah tui an hmu bawk.

Kan taksaah hian `Circumflex` type artery dang a awm em?

Ni e, thinlunga ``Circumflex Artery'' bakah hian kan taksaah hian thisen kalna kawng chi dang, he hming hi a awm bawk.

• Femoral Circumflex Arteries: Hengte hi kan kawr chhunga thisen kalna kawng lian ber Femoral Artery atanga branch chhuak thuk tak pahnih an ni. Femoral Artery hian pum atanga thisen chu ke hnuai lam thlengin a phur a. A chang chuan coronary artery bypass surgery an tih lai hian doctor ten an kekawr atanga Circumflex Artery an la a, graft atan an hmang thin.
• Humeral Circumflex Arteries te chu a awm a:Chungte chu kan armpit area-a `(Axillary Artery)` hmanga then a ni. He `(Axillary Artery)` hi rilru atanga thisen phurtu a ni a, kekawrte leh kutphah thlengin a phur a ni. A bik takin kan kut chunglam ruh (`Humerus`) hi he `(Posterior Humeral Circumflex Artery)` hian thisen a pe ber a ni.

`Circumflex Artery` tibuaitu natnate chu engte nge ni?

Coronary artery dang ang bawkin circumflex artery pawh hi coronary artery disease (CAD) an tih natnain a nghawng thei bawk. Hei hi thisen kalna kawng chhungah thau (plaque) a lo awm a, chu chuan a block a ni. Tui pipe rust-in a tikhawlo ang mai a ni.

Hetianga plaque awmkhawm leh artery wall thickening hi atherosclerosis an ti a, chu chu “arteries hardening” emaw “hardening of the arteries” tihna a ni. He CAD natna hi enkawl tha a nih loh chuan natna hlauhawm tak tak , heart attack, heart failure, leh stroke te a thlen theihna a tipung a ni.

`Circumflex Artery`-a blockage awm hian eng symptoms nge a neih?

Hetianga thisen kalna kawng a zim avang hian thisen kal a tlahniam chuan rilru natna a awm thei a ni. Hei hi ``Angina'' an ti a. Hetiang ``Angina'' natna hian heart attack a thlen thei a ni. Hei hi medical emergency a nih avangin 911 ah i call nghal tur a ni.

Circumflex artery-a blockage pawh CAD-a tel a nih avangin a symptoms pawh a inang vek. Hetiang hi i tawng thei a ni:
